Description

Resource configuration method, network device and computer storage medium

technical field

The present application belongs to the technical field of communication, and in particular relates to a resource allocation method, network equipment and computer storage medium.

Background technique

When the terminal device is in a discontinuous reception (Discontinuous Reception, DRX) mode, the network device at the base station side needs to instruct the terminal device to measure and report Channel State Information (CSI).

The CSI measurement resource and the reporting resource of the terminal device are configured by the network device at the base station side. At present, when the network device at the base station side configures CSI measurement resources and reporting resources for the terminal device, it often adopts the same resource configuration scheme.

However, in different DRX cycles, the state of the terminal device is quite different, and it is difficult to adapt to the differentiated terminal state in the wireless communication system by adopting a single resource allocation scheme, which may easily cause too much or too little resource allocation.

Contents of the invention

In view of this, the embodiment of the present application provides a resource allocation method, network equipment, and computer storage medium to solve the problem that it is difficult to apply a single resource allocation scheme in the prior art to the differentiated terminal states in the wireless communication system, and it is easy to cause resource Problems with too much or too little configuration.

The first aspect of the embodiments of the present application provides a resource allocation method, including:

The network device acquires a first parameter corresponding to the DRX cycle to be configured, and queries resource configuration information corresponding to the first parameter in a preset resource configuration table;

The network device sends the resource configuration information to the terminal device to instruct the terminal device to measure and report channel state information according to the resource configuration information.

It should be noted that the DRX cycle to be configured may be set according to a configuration scheme of a user. The DRX cycle to be configured may be a DRX cycle with data transmission, or may be every DRX cycle.

The type of the first parameter can be selected according to the actual situation. The preset resource configuration information table is a resource configuration table preset by the user. The preset resource configuration table records the correspondence between the first parameter and resource configuration information. The user can determine the resource configuration information corresponding to each first parameter through experimental tests, theoretical calculations, etc., so as to obtain the corresponding relationship between the first parameter and the resource configuration information, and establish a preset resource configuration table.

In a possible implementation manner of the first aspect, the first parameter is the cycle length of the DRX cycle to be configured;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device acquires the cycle length of the DRX cycle to be configured, and queries resource configuration information corresponding to the cycle length in a preset resource configuration table.

It should be noted that the longer the cycle length of the DRX cycle to be configured, the greater the possibility of data interaction between the network device and the user terminal device within the DRX cycle to be configured, and the network device should configure more CSI measurement resources and Reporting resources; the shorter the period of the DRX cycle to be configured, the less likely the data interaction between the network device and the user terminal equipment will occur in the DRX cycle to be configured, and the network device should configure fewer CSI measurement resources and reporting resources.

Therefore, the cycle length of the DRX cycle to be configured may be used as the first parameter, and resource configuration may be performed according to the cycle length of the DRX cycle to be configured.

In another possible implementation manner of the first aspect, the first parameter is a cycle type of the DRX cycle to be configured;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device obtains the cycle type of the DRX cycle to be configured, and queries resource configuration information corresponding to the cycle type in a preset resource configuration table.

It should be noted that the cycle type of the DRX cycle to be configured may include a short DRX cycle and a long DRX cycle. When the cycle type of the DRX cycle to be configured is a short DRX cycle, the possibility of data interaction between the network device and the user equipment during the DRX cycle to be configured is small, and the network device should configure fewer CSI measurement resources and reporting resources ; When the cycle type of the DRX cycle to be configured is a long DRX cycle, the data interaction between the network device and the user terminal device is more likely to occur in the DRX cycle to be configured, and the network device should configure more CSI measurement resources and report resource.

Therefore, the cycle type of the DRX cycle to be configured may be used as the first parameter, and resource configuration is performed according to the cycle type of the DRX cycle to be configured.

In another possible implementation manner of the first aspect, the first parameter is the total sleep time of the terminal device before the DRX cycle to be configured;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device obtains the total sleep time of the terminal device before the DRX cycle to be configured, and determines the sleep time interval in which the total sleep time is located;

The network device queries resource configuration information corresponding to the sleep time interval in a preset resource configuration table.

It should be noted that if the total sleep time of the terminal device before the DRX cycle to be configured is longer, the network device should configure more CSI measurement resources and reporting resources; if the total sleep time of the terminal device before the DRX cycle to be configured The shorter the time, the network device should configure fewer CSI measurement resources and reporting resources.

Therefore, the total sleep time of the terminal device before the DRX cycle to be configured can be used as the first parameter, and resource configuration is performed according to the total sleep time of the terminal device before the DRX cycle to be configured.

In another possible implementation manner of the first aspect, the first parameter is the total sleep times of the terminal device before the DRX cycle to be configured;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device acquires the total sleep times of the terminal device before the DRX cycle to be configured, and queries resource configuration information corresponding to the total sleep times in a preset resource configuration table.

It should be noted that if the total sleep times of the terminal device before the DRX cycle to be configured is greater, the network device should configure more CSI measurement resources and reporting resources; if the total sleep times of the terminal device before the DRX cycle to be configured The smaller the number of times, the network device should configure fewer CSI measurement resources and reporting resources.

Therefore, the total sleep times of the terminal device before the DRX cycle to be configured can be used as the first parameter, and resource configuration is performed according to the total sleep times of the terminal device before the DRX cycle to be configured.

In another possible implementation manner of the first aspect, the first parameter is a signal type of a power saving signal corresponding to the DRX cycle to be configured;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device acquires the signal type of the power saving signal corresponding to the DRX cycle to be configured, and queries resource configuration information corresponding to the signal type in a preset resource configuration table.

It should be noted that the signal type of the power saving signal may include a wake up signal (Wake Up Signal, WUS) signal and a sleep signal (Go to Sleep Signal, GTS).

When the signal type of the power saving signal is a WUS signal, it means that the terminal device needs to perform data interaction with the network device in the DRX cycle to be configured. At this time, the network device should configure more CSI measurement resources and reporting resources; when the power saving signal When the signal type is a GTS signal, it means that the terminal device is in a dormant state during the DRX cycle to be configured and does not need to perform data interaction with the network device. At this time, the network device should configure fewer CSI measurement resources and reporting resources.

Therefore, the signal type of the power saving signal corresponding to the DRX cycle to be configured may be used as a first parameter, and resource configuration is performed according to the signal type of the power saving signal corresponding to the DRX cycle to be configured.

In another possible implementation manner of the first aspect, the first parameter is the current traffic volume of the terminal device;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device measures the current traffic volume of the terminal equipment, and determines the traffic volume interval in which the traffic volume is located;

The network device queries resource configuration information corresponding to the service volume interval in a preset resource configuration table.

It should be noted that the network device may count the traffic of the user terminal equipment during the traffic measurement period, and use it as the current traffic of the terminal equipment. The greater the current service volume of the terminal device, the more data the network device needs to interact with the terminal device in the DRX cycle to be configured, and the network device should configure more CSI measurement resources and reporting resources; the current service of the terminal device The smaller the amount, it means that in the DRX cycle to be configured, the network device needs to interact with the terminal device with less data, and the network device should configure fewer CSI measurement resources and reporting resources.

Therefore, the current traffic volume of the terminal device may be used as the first parameter, and resource allocation is performed according to the current traffic volume of the terminal device.

In another possible implementation manner of the first aspect, the first parameter is the priority identified by the quality of service level corresponding to the current service of the terminal device;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device obtains the priority of the QoS level identifier corresponding to the current service of the terminal device, and queries resource configuration information corresponding to the priority of the QoS level ID in a preset resource configuration table.

It should be noted that, for services with higher priority of QCI (QoS Class Identifier, service quality level identification), such as GBR (Guaranteed Bit Rate, guaranteed bit rate) services, more CSI measurement resources and reporting resources should be configured To ensure the service quality of the business; and for the business with a lower QCI priority, such as Non-GBR business, relatively speaking, the network device can be configured with fewer CSI measurement resources and reporting resources.

Therefore, the priority of the QoS level identifier corresponding to the current service of the terminal device may be used as the first parameter, and resource configuration is performed according to the priority of the QoS level identifier corresponding to the current service of the terminal device.

In another possible implementation manner of the first aspect, the first parameter is the distance between the terminal device and the network device;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device obtains the distance between the terminal device and the network device, and determines the distance interval in which the distance is located;

The network device queries resource configuration information corresponding to the distance interval in a preset resource configuration table.

It should be noted that, if the current terminal device is far away from the network device, it means that the terminal device may be at the cell edge. At this time, if the terminal device does not meet the trigger conditions for exiting the DRX mode, that is, the terminal device does not meet the cell handover or the terminal device is in the radio resource control connected (Radio Resource Control Connected, RRC_Connected) state because the channel environment is poor, the trigger exits the DRX mode condition, the channel quality of the terminal equipment fluctuates and the delay is very large. At this time, if the CSI measurement resources and reporting resources configured by the network device are few, the terminal device may not be able to report the Channel Quality Indication (CQI) in time to adjust the Modulation and Coding Scheme (MCS). The throughput performance will be affected to some extent.

Therefore, the distance between the terminal device and the network device may be used as the first parameter, and resource configuration is performed according to the distance between the terminal device and the network device.

In another possible implementation manner of the first aspect, the first parameter is a moving speed of the terminal device;

Correspondingly, the network device acquires the first parameter corresponding to the DRX cycle to be configured, and querying the resource configuration information corresponding to the first parameter in a preset resource configuration table includes:

The network device obtains the moving speed of the terminal device, and determines the speed interval in which the moving speed is located;

The network device queries resource configuration information corresponding to the speed range in a preset resource configuration table.

It should be noted that if the mobile speed of the terminal device is high, and the terminal device has no penalty for exiting the DRX mode, it may happen that the terminal device has left the coverage of the original network device before completing the CSI measurement. As a result, network switching failure of the terminal equipment and call drop occur. Therefore, the moving speed of the terminal device can be configured with CSI measurement resources and reporting resources. If the mobile speed of the terminal device is fast, the network device should configure more CSI measurement resources and reporting resources to instruct the terminal device to complete CSI measurement and reporting as soon as possible to reduce network handover failures and call drops; if the mobile speed of the terminal device If it is slower, relatively speaking, the network device can configure fewer CSI measurement resources and reporting resources.

Therefore, the moving speed of the terminal device may be used as the first parameter, and resource allocation is performed according to the moving speed of the terminal device.

In addition, in the description of the present application, terms such as "first", "second", and "third" are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

The embodiments of the present application may be applied to wireless communication systems. A wireless communication system is generally composed of cells (cells), and each cell includes a base station (Base Station, BS), and the base station provides communication services for multiple terminal devices. The base station includes a baseband unit (Baseband Unit, BBU) and a remote radio unit (Remote Radio Unit, RRU). BBU and RRU can be placed in different places, for example: RRU is far away and placed in an open area away from high traffic, and BBU is placed in the central computer room. The BBU and RRU can also be placed in the same equipment room. The BBU and the RRU may also be different components under one rack.

In the embodiment of the present application, the base station is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The base station may include various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, transmission reception points (Transmission Reception Point, TRP) and so on. In systems using different radio access technologies, the names of devices with base station functions may be different. For example, in a Long Term Evolution (LTE) system, it is called an evolved NodeB (evolved NodeB, eNB or eNodeB), in the third generation (3rd Generation, 3G) system, it is called Node B (Node B, NB) and the like. For convenience of description, in all the embodiments of the present application, the above-mentioned apparatuses for providing wireless communication functions for terminal equipment are collectively referred to as network equipment.

The terminal devices involved in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems. The terminal equipment may also be called a mobile station (Mobile Station, MS) or a terminal (Terminal), and may also include a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, Personal digital assistant (Personal Digital Assistant, PDA) computer, tablet computer, wireless modem (modem), handheld device (handset), laptop computer (laptop computer), machine type communication (MachineType Communication, MTC) terminal, etc. For convenience of description, in all embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.

In the current long term evolution (Long Term Evolution, LTE) system and the fifth generation wireless access system (5thGeneration, 5G) new air interface (New Radio, NR), the physical downlink performed by the user equipment (User Equipment, UE) Control channel (Physical Downlink Control Channel, PDCCH) detection contributes a considerable proportion of UE power consumption.

The PDCCH is used to transmit information for the downlink, and the information it transmits includes public control information (such as system information, paging information, etc.) and user-specific information (downlink resource allocation instructions, uplink power control parameters, etc.).

In the actual application process, the data flow due to the packet is usually bursty. During a period of time, there is data transmission between the network device and the UE, but there may be no data transmission for a long period of time in the future. Therefore, most of the PDCCH monitoring performed by the UE does not detect any indication, and these PDCCH monitoring without any indication will cause considerable power consumption of the UE.

Based on the above situation, discontinuous reception DRX (Discontinuous Reception, DRX) technology is introduced in both LTE and 5G NR. In the DRX technology, when there is no data transmission, the power consumption of the UE can be reduced by making the UE stop detecting the PDCCH and stopping receiving the corresponding data transmission, thereby improving the battery life of the UE.

In the DRX technology, a network device at the base station side can configure a DRX cycle (DRX cycle) for a UE in a radio resource control state. As shown in FIG. 2 , the DRX cycle includes a time zone of On Duration (On Duration) and a time zone of Discontinuous Reception Time (Opportunity for DRX).

During the On Duration, the UE may detect the PDCCH and/or receive a Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH). The UE starts a timer at the start position of each DRX cycle time (that is, the time start position of OnDuration), and the time length of the timer is the time length of OnDuration. This timer can be called a duration timer (DRX -onDurationTimer), the range of DRX-onDurationTimer can be set according to the actual situation, for example, the range of DRX-onDurationTimer can be set to 1-1200ms.

As shown in Figure 3, the UE detects the PDCCH within the time range of DRX-onDurationTimer. If the UE does not detect the PDCCH within the time range of the DRX-onDurationTimer, the UE enters the sleep state after the DRX-onDurationTimer expires, thereby reducing the power consumption of the UE. If the UE detects the PDCCH within the time range of DRX-onDurationTimer, the UE will start the inactivity timer (DRX-InactivityTimer) in the DRX mechanism. If the UE continues to detect the PDCCH within the running time of the DRX-InactivityTimer, the UE will reset the inactivity timer and start counting again. If the inactivity timer is running, even if the DRX-onDurationTimer expires, the UE still needs to continue to detect the PDCCH until the DRX-InactivityTimer expires.

In the DRX mechanism, there are other timers, such as DRX downlink retransmission timer (drx-RetransmissionTimerDL) and DRX uplink retransmission timer (drx-RetransmissionTimerUL). However, the functions of these timers are irrelevant to the solutions of the embodiments of the present application, and will not be described in detail here. If any one of the above-mentioned timers (including DRX-onDurationTimer, DRX-InactivityTimer and other timers) is running, the UE will be in active time (Active Time). In the DRX mechanism, if the UE is in the Active Time, the UE needs to detect the PDCCH. It should be noted that there are other situations that may cause the UE to be in the Active Time, but are not related to the solution of the embodiment of the present application, and will not be described in detail here.

The DRX cycle, onDuration and Opportunity for DRX are all configured to the UE by the network equipment on the base station side. As shown in FIG. 4 , the DRX cycle is divided into a short DRX cycle (short DRX cycle) and a long DRX cycle (long DRX cycle). The cycle lengths of the short DRX cycle and the long DRX cycle are different, and the UE switches between DRX cycles of two different cycle lengths according to specific rules.

Generally speaking, when the DRX-InactivityTimer times out or receives a DRX Media Access Control Element (MediaAccess Control-Control Element, MAC-CE), if the UE is not configured with a short DRX cycle, it will directly use the long C-DRX cycle; If the short DRX cycle is configured for the UE, the UE uses the short DRX cycle and starts or restarts the short DRX cycle timer (drxShortCycleTimer). When the drxShortCycleTimer times out, the UE uses the long DRX cycle.

When the UE uses short DRX cycle or long DRX cycle, if the subframe number meets the following conditions, start DRX-onDurationTimer:

(SFN*N+sn)mod(short DRX cycle)＝(drxStartOffset)mod(short DRX cycle)(SFN*N+sn)mod(short DRX cycle)＝drxStartOffset

Among them, SFN (System Frame Number) is the system frame number, N is a positive integer, N is the number of subframes in one SFN cycle, sn (subframe number) is the subframe number, mod is a modulo function, and drxStartOffset is the cycle start sub frame number.

In the actual application process of DRX technology, due to the bursty and sparse nature of data transmission in time, even if the UE only performs PDCCH detection during the active time of DRX, there is still a considerable proportion of which no indication can be detected, and the power consumption Serious waste. Especially in the NR system, the UE will work in a larger radio frequency and baseband bandwidth, resulting in higher wasted power consumption of the UE.

Based on the above situation, a power saving signal (Power Saving Signal, PoSS) will be introduced in the NR Rel-16 technical standard to further reduce UE power consumption. Before the OnDuration of the DRX cycle, the network device on the base station side sends a PoSS to the UE to indicate whether the UE needs to wake up to perform one of operations such as monitoring PDCCH, receiving PDSCH, and performing measurement reporting in the next one or more DRX cycles or more.

PoSS can be a wake up signal (Wake Up Signal, WUS), that is, the UE needs to wake up. When PoSS is WUS, the UE behaves as previously specified by C-DRX. Alternatively, PoSS may also be a sleep signal (Go to Sleep, GTS), that is, the UE sleeps in the next C-DRX cycle without PDCCH monitoring.

For a UE that supports WUS, the network device on the base station side can send WUS in the form of Discontinuous Transmission (DTX) at the PoSS occasion (power saving signal time) before the OnDuration start position of the DRX cycle, that is, the network device on the base station side It is decided whether to send WUS on PoSS occasion according to the demand of scheduling data. The UE needs to judge whether the base station sends WUS at the PoSS occasion. As shown in Figure 5, if the UE does not detect WUS on the PoSSoccasion or the detected WUS indicates that the UE has no data scheduling within the corresponding OnDuration period, the UE can directly enter the sleep state without PDCCH monitoring. As shown in Figure 6, if the UE detects WUS on PoSSoccasion, and the detected WUS indicates that the UE has data scheduling within the corresponding OnDuration time period, the UE will wake up, and the UE can start DRX- onDurationTimer, detect PDCCH.

The blank rectangle in Figure 6 indicates the OnDuration period, and the rectangle marked with a slash indicates DRX-InactivityTimer. The UE detects WUS on the PoSS occasion, and the detected WUS indicates that the UE has data scheduling within the corresponding OnDuration period. Then the UE gradually It is woken up and starts to detect PDCCH during the OnDuration period. When the UE detects the PDCCH, it starts the DRX-InactivityTimer. After the DRX-InactivityTimer ends, the DRX-onDurationTimer has not yet ended, indicating that the OnDuration period has not yet ended, and the PDCCH continues to be monitored. After the DRX-onDurationTimer ends, the UE gradually enters the sleep state.

Similar to WUS, for a UE that supports GTS, the network device on the base station side can send the GTS in the form of DTX at the PoSS occasion before the OnDuration start position of the DRX cycle. The UE needs to determine whether the base station sends the GTS at the PoSS occasion. If the UE detects a GTS on the PoSS occasion, and the detected GTS indicates that the UE has no data scheduling within the corresponding OnDuration period, the UE will re-enter the dormant state. If the UE does not detect the GTS on the PoSSoccasion or the detected GTS indicates that the UE has data scheduling within the corresponding OnDuration period, the UE will wake up and monitor the PDCCH.

In other possible situations, the network device at the base station side may instruct the UE to enter a sleep state or stop detecting the PDCCH for a period of time through the GTS, and this time may be called a sleep duration (Sleep Duration). As shown in Figure 7, when the UE detects the PDCCH within the OnDuration period, it starts the DRX-InactivityTimer. The UE detects GTS within the duration of DRX-InactivityTimer. The GTS that includes the sleep time T indicates that the network equipment on the base station side determines that the UE does not need to schedule any data and send PDCCH to the UE within the continuous time T after receiving the GTS signal. . Therefore, after detecting and analyzing the GTS that includes the sleep time T, the UE enters the sleep state without PDCCH detection, turns off some radio frequency or baseband circuits, and wakes up after the sleep time T to detect PoSS signals or PDCCH. In this way, unnecessary power consumption of the UE can be reduced.

PoSS can be a sequence signal or a data signal. When PoSS is a data signal, PoSS can be downlink control information (Downlink Control Information, DCI), physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), media access control control unit (Media Access Control-Control-Element, MAC-CE), One of digital signals such as radio resource control (Radio Resource Control, RRC) signaling.

In the current C-DRX, the UE can only perform CSI measurement and CSI reporting during the Active time in DRX. The network equipment on the base station side cannot obtain CSI information in a timely and effective manner at the start of the DRX cycle to adjust the data transmission link, thereby reducing the frequency band efficiency of the system and possibly increasing UE power consumption due to data retransmission.

A compensation time (offset duration) is usually set between PoSS occasion and OnDuration. The offset duration is used for UE to perform PoSS detection and analyze the meaning of its indication, time-frequency synchronization, channel state information (Channel State Information, CSI) measurement, beam management Wait for processing. The more processing the UE needs to perform, the longer it takes.

In order to improve the reliability of receiving data, the network equipment on the base station side can consider placing reference signals in the offset duration for CSI measurement and reporting when there is data scheduling, and trigger CSI reporting based on PoSS signals, thereby improving OnDuration and the next DRX Cycle data transmission efficiency. The above-mentioned reference signal may be a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), a demodulation reference signal (Demodulation Reference Signal, DM-RS), a time domain frequency domain tracking reference signal (Time/Frequency Tracking Signal, TRS ), synchronization signal block (Synchronization Signal Block, SSB) signal and other types of reference signals. The number of reference signals can be one or more than one.

At this time, PoSS can be used as a power saving signal to instruct the UE to wake up to send and receive data in the current DRX cycle, and can also be used as a trigger signal for CSI reporting. The network equipment on the base station side does not need a dedicated PDCCH to trigger CSI reporting, reducing network signaling overhead. In addition, CSI reporting is reported on demand, and only when the UE is woken up by PoSS to transmit and receive data, it is triggered to report CSI, so that the measurement and reporting of CSI are more effective, so that the network equipment on the base station side can obtain timely information during the active time of DRX. CSI information for data transmission.

However, when the network equipment on the base station side configures CSI measurement resources and reporting resources, it often adopts the same resource allocation scheme. A single resource allocation scheme is difficult to apply to differentiated UE states in wireless communication systems such as NR, and it is easy to cause resource allocation. too high or too low.

In view of this, the embodiment of the present application provides a resource configuration method, the network device obtains the first parameter related to the DRX cycle to be configured, the first parameter is used to represent the state of the DRX cycle to be configured, and is determined according to the first parameter Channel state measurement resource and resource reporting configuration scheme, so as to perform reasonable resource allocation according to the state of the UE, and realize a more reasonable and effective resource allocation scheme while ensuring that the UE can ensure power saving and gain, and solve the problem in the prior art It is difficult to apply a single resource allocation scheme to different UE states in a wireless communication system, and it is easy to cause the problem of too much or too little resource allocation.

Next, from the perspective of network equipment at the base station side, the resource configuration method provided by the embodiment of the present application is introduced in detail. Referring to the flowchart of the resource allocation method shown in Figure 1, the method includes:

S101. The network device acquires a first parameter corresponding to the discontinuous reception DRX cycle to be configured, and queries resource configuration information corresponding to the first parameter in a preset resource configuration table;

The DRX cycle to be configured can be set according to the user's configuration scheme. In some possible implementation manners, the DRX cycle to be configured may be a DRX cycle with data transmission. In this configuration solution, the network device can obtain the CSI information in the DRX cycle to configure the data transmission link and improve the frequency band efficiency of the system.

However, this solution only considers the DRX cycle with data scheduling, and does not consider the DRX cycle in the dormant state. The NR system transmits high-frequency information based on beams. At this time, if the report of the DRX cycle in the dormant state is ignored, the terminal device may fail to receive high-frequency signals such as PoSS signals, resulting in increased scheduling delays.

For example, DRX cycle 1 to DRX cycle 5 are five DRX cycles arranged in sequence on the time axis. In DRX cycle 1, there is data interaction between the network device and the user's terminal device, DRX cycles 2 to 4 are DRX cycles in a dormant state, and in DRX cycle 5, there is data interaction between the network device and the user's terminal device.

At this time, if only the DRX cycle with data scheduling is regarded as the DRX cycle to be configured, then only in DRX cycle 1 and DRX cycle 5, the terminal device needs to measure and report the CSI. However, since the terminal device has been dormant for 3 DRX cycles, the system state of the terminal device may change greatly during DRX cycle 5, for example, the orientation of the antenna array changes. When network devices transmit high-frequency information in the form of beams, the beams have strong directivity and narrow coverage angles. If the system status of terminal devices changes greatly and the network devices do not adjust the data transmission link, Then the network device may not be able to transmit the PoSS signal or other high-frequency signals to the terminal device, resulting in the failure of the terminal device to receive data, resulting in increased scheduling delay.

Therefore, in some other possible implementation manners, the DRX cycle to be configured may be every DRX cycle, that is, regardless of whether the network device needs to perform data interaction with the terminal device in the DRX cycle, the cycle is regarded as the DRX cycle to be configured. cycle. At this time, the network device can obtain CSI information in time even when the terminal device has experienced a long period of dormancy, so that the network device is more robust when transmitting high-frequency information based on the beam, and reduces the data scheduling delay.

For example, referring to the previous example, if each DRX cycle is regarded as a DRX cycle to be configured, even in the dormant state, the network device will configure the CSI measurement resources of DRX cycle 2 to DRX cycle 4 for the terminal device, and according to The CSI fed back by the terminal device (such as Channel Quality Indication (CQI) and other information) adjusts the data transmission link. Even if the system status of the terminal device changes in DRX cycle 4, the change range is higher than that of DRX cycle 2 to DRX cycle The change range of the system state of the terminal equipment within 4 is small, and the network equipment can relatively accurately transmit high-frequency signals such as PoSS signals to the terminal equipment in DRX cycle 5, improving the transmission performance of high-frequency information and reducing data scheduling delay.

After the DRX cycle to be configured is determined, the network device may acquire a first parameter corresponding to the DRX cycle to be configured. In some possible implementation manners, the network device may configure CSI measurement resources and report resources within the DRX cycle to be configured. However, in this way, the network device cannot obtain CSI information in a timely and effective manner to adjust the data transmission link at the beginning of the DRX cycle to be configured, thereby reducing the frequency band efficiency of the system and possibly causing terminal problems due to data retransmission. Increased device power consumption.

In some other possible implementation manners, in order to improve the reliability of data reception, the network device may start the DRX cycle to be configured, that is, at the end of the previous DRX cycle of the DRX cycle to be configured (for example, the end of the previous DRX cycle offset duration) to obtain the first parameter corresponding to the DRX cycle to be configured to configure CSI measurement resources and report resources, so that the network device can obtain the CSI information in time before the start of the DRX cycle to be configured. Make adjustments to improve the frequency band efficiency of the system and reduce the power consumption of the terminal equipment.

The specific type of the first parameter can be set according to the actual situation. In some possible implementation manners, the first parameter may be the cycle length of the DRX cycle to be configured. The longer the cycle length of the DRX cycle to be configured, the greater the possibility of data interaction between the network device and the user terminal device within the DRX cycle to be configured, and the network device should configure more CSI measurement resources and reporting resources; to be configured The shorter the period of the DRX cycle, the less possibility of data interaction between the network device and the user terminal equipment in the DRX cycle to be configured, and the network device should configure fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device can obtain the cycle length corresponding to the DRX cycle to be configured by querying cycle configuration parameters (such as gNBDrxParamGroup.LongDrxcycle, gNBDrxParamGroup.ShortDrxcycle, etc.), and query in the preset resource configuration table Resource configuration information corresponding to the above cycle length.

In some other possible implementation manners, the first parameter may be a cycle type of the DRX cycle to be configured. The cycle type of the terminal device may include a short DRX cycle and a long DRX cycle. When the cycle type of the DRX cycle to be configured is a short DRX cycle, the cycle length of the short DRX cycle is short, and the possibility of data interaction between the network device and the user terminal equipment during the DRX cycle to be configured is small, and the network device should configure Fewer CSI measurement resources and reporting resources; when the cycle type of the DRX cycle to be configured is a long DRX cycle, the cycle length of the long DRX cycle is longer, and the network device interacts with the user equipment during the DRX cycle to be configured. The possibility is relatively high, and the network device should be configured with more CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may obtain the cycle type corresponding to the DRX cycle to be configured, and query resource configuration information corresponding to the above cycle type in a preset resource configuration table.

In some other possible implementation manners, the first parameter may be the total sleep time of the terminal device before the DRX cycle to be configured. If the total sleep time of the terminal device before the DRX cycle to be configured is longer, the system state of the terminal device changes more, and the network device should configure more CSI measurement resources and reporting resources; if the terminal device is in the DRX cycle to be configured The shorter the previous total sleep time, the smaller the system state change of the terminal device, and the network device should be configured with fewer CSI measurement resources and reporting resources. Therefore, before the start of the DRX cycle to be configured, the network device can obtain the total sleep time of the terminal device before the DRX cycle to be configured, and query in the preset resource configuration table according to the sleep time interval of the total sleep time. Resource configuration information corresponding to the sleep time interval above.

In some other possible implementation manners, the first parameter may be the total sleep times of the terminal device before the DRX cycle to be configured. If the terminal device has more sleep times before the DRX cycle to be configured, the system state of the terminal device changes more, and the network device should configure more CSI measurement resources and reporting resources; if the terminal device is in the DRX cycle to be configured The smaller the previous total sleep times, the smaller the system state change of the terminal device, and the network device should be configured with fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may obtain the total sleep times of the terminal device before the DRX cycle to be configured, and query resource configuration information corresponding to the total sleep times in a preset resource configuration table.

In some other possible implementation manners, the first parameter may be a signal type of a power saving signal (PoSS) that the network device is about to deliver to the terminal device. The power saving signal is used to indicate whether the terminal equipment is in the wake-up state or the sleep state in the DRX cycle to be configured. Signal types of the power saving signal may include a WUS signal and a GTS signal. When the signal type of the power saving signal is a WUS signal, it means that the terminal device needs to perform data interaction with the network device in the DRX cycle to be configured. At this time, the network device can configure more CSI measurement resources and reporting resources; when the power saving signal When the signal type is a GTS signal, it means that the terminal device is in a dormant state during the DRX cycle to be configured and does not need to perform data interaction with the network device. At this time, the network device can configure fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device can obtain the signal type of the power saving signal corresponding to the DRX cycle to be configured, and query the resource configuration corresponding to the signal type of the power saving signal in the preset resource configuration table information.

In some other possible implementation manners, the first parameter may be the current traffic volume of the terminal device. The network device can count the traffic of the user terminal equipment within the traffic volume measurement period (CellDrxPara.DataAmountStatTimer), and use it as the current traffic volume of the terminal equipment. In the case that the traffic volume of the terminal device is not higher than the traffic threshold value for exiting DRX mode (such as CellDrxPara.FddExitDrdThd, CellDrxPara.TddExitDrdThd), the more current traffic volume of the terminal device, it means that it is within the DRX cycle to be configured , the more data the network device needs to interact with the terminal device, the more CSI measurement resources and reporting resources the network device should configure; The less data the terminal device interacts with, the less CSI measurement resources and reporting resources should be configured on the network device. Therefore, before the start of the DRX cycle to be configured, the network device can obtain the current traffic volume of the terminal equipment, determine the traffic volume interval in which the above traffic volume is located, and query the resource corresponding to the above traffic volume interval in the preset resource configuration table configuration information.

In some other possible implementation manners, the first parameter may be a priority of a quality of service class identifier (QoS Class Identifier, QCI) corresponding to a current service of the terminal device. Generally speaking, for services with higher QCI priority, such as guaranteed bit rate (Guaranteed Bit Rate, GBR) services (QCI=5, 6, 7, 8, 9, 69, 70), more CSI measures resources and reports resources to guarantee the service quality of the business; for services with lower QCI priority, such as non-guaranteed bit rate (Non Guaranteed Bit Rate, Non-GBR) business (QCI=1,2,3,4 ,65,66), relatively speaking, network devices can be configured with fewer CSI measurement resources and reporting resources. Therefore, before the start of the DRX cycle to be configured, the network device can obtain the priority of the service quality level identifier corresponding to the current service of the terminal device, and query the resource configuration information corresponding to the above priority in the preset resource configuration table.

In some other possible implementation manners, the first parameter may be the distance between the current terminal device and the network device. If the current terminal device is far away from the network device, it indicates that the terminal device may be at the cell edge. At this time, if the terminal device does not meet the trigger conditions for exiting the DRX mode, that is, the terminal device does not meet the cell handover or the terminal device is in the radio resource control connected (Radio Resource Control Connected, RRC_Connected) state because the channel environment is poor, the trigger exits the DRX mode condition, the channel quality of the terminal equipment fluctuates and the delay is very large. At this time, if the CSI measurement resources and reporting resources configured by the network device are few, the terminal device may not be able to report the Channel Quality Indication (CQI) in time to adjust the Modulation and Coding Scheme (MCS). Throughput performance will be affected to some extent. Therefore, the network device can configure CSI measurement resources and report resources according to the distance between the terminal device and the network device. Before the start of the DRX cycle to be configured, the network device can query the location parameters (such as DistBasedHO.DistBasedHOThd) to obtain the distance between the terminal device and the network device, determine the distance interval of the above distance, and query the preset resource configuration table. Resource configuration information corresponding to the distance interval above.

In some other possible implementation manners, the first parameter may be the current moving speed of the terminal device. If the mobile speed of the terminal device is high, and the terminal device does not meet the trigger conditions for exiting the DRX mode, the terminal device may have left the coverage of the original network device before the terminal device completes the CSI measurement, resulting in the terminal device Network switching fails and calls are dropped. Therefore, the moving speed of the terminal device can be configured with CSI measurement resources and reporting resources. If the mobile speed of the terminal device is fast, the network device should configure more CSI measurement resources and reporting resources to instruct the terminal device to complete CSI measurement and reporting as soon as possible to reduce network handover failures and call drops; if the mobile speed of the terminal device If it is slower, relatively speaking, the network device can configure fewer CSI measurement resources and reporting resources. Therefore, before the start of the DRX cycle to be configured, the network device can acquire the position change information of the terminal device in the speed measurement period, and calculate the current moving speed of the terminal device according to the above position change information. After the network device obtains the current moving speed of the terminal device, it determines the speed interval in which the above moving speed is located, and queries resource configuration information corresponding to the above speed interval in a preset resource configuration table.

It should be understood that the above description about the first parameter is only a schematic example of the first parameter in this embodiment, and in other possible implementation manners, the first parameter may also be an uplink modulation and coding scheme (Modulation and Coding Scheme) , MCS) index, initial block error rate (Initial Block Error Rate, IBLER) threshold of uplink data, maximum time advance (time advanced, TA) and other parameters related to the DRX cycle to be configured. The specific type of the first parameter should be determined according to the actual situation, and the above example should not be construed as a limitation on the type of the first parameter. Moreover, in the above description, although only the case where the first parameter is a certain kind of parameter is described, the first parameter may be a certain kind of parameter, or the first parameter may be two or more kinds of parameters collection. For example, the first parameter may be the cycle type of the DRX cycle to be configured, and the network device queries the resource configuration information corresponding to the above cycle type in the preset resource configuration table; or the first parameter is the cycle type of the DRX cycle to be configured In combination with the traffic volume, the network device queries the resource configuration information corresponding to the above cycle type and the traffic volume interval in which the traffic volume is located in the preset resource configuration table.

The resource configuration information mentioned above may include the time-frequency position of the CSI measurement reference signal, the number of the CSI measurement reference signal, the period of the CSI measurement reference signal, the time-frequency position of the CSI reporting resource, the number of the CSI reporting resource, the number of the CSI reporting resource One or more of configuration parameters such as period.

The above-mentioned CSI measurement reference signal may include a channel state information reference signal (Channel StateInformation Reference Signal, CSI-RS), a time-frequency domain tracking reference signal (Time/FrequencyTracking Signal, TRS), a demodulation reference signal (Demodulation Reference Signal, DM-RS), Synchronization Signal Block (Synchronization Signal Block, SSB) and other signals or a combination of one or more.

The CSI mentioned above may include Channel Quality Indication (CQI), Precoding Matrix Indicator (Precoding Matrix Indicator, PMI), Rank Indicator (Rank Indicator, RI), Layer Indicator (Layer Indicator, LI) One or more combinations of such signals.

The preset resource configuration table mentioned above is a resource configuration table preset by the user. The preset resource configuration table records the correspondence between the first parameter and resource configuration information. It can be understood that the user can determine the resource configuration information corresponding to each first parameter through experimental tests, theoretical calculations, etc., so as to obtain the corresponding relationship between the first parameter and the resource configuration information, and establish a preset resource configuration table.

S102. The network device sends the resource configuration information to the terminal device, so as to instruct the terminal device to measure and report channel state information according to the resource configuration information.

After the network device queries the resource configuration information corresponding to the first parameter from the preset resource configuration table, it sends the resource configuration information to the terminal device.

In some possible implementation manners, the foregoing resource configuration information may be a specific resource configuration scheme. The network device sends the specific resource allocation scheme to the terminal device.

In some other possible implementation manners, the above resource configuration information may be an index. The resource configuration information index table is stored on the terminal device. After the network device sends the index to the terminal device, the terminal device can query the specific resource configuration scheme from the resource configuration information index table according to the index.

In some other possible implementation manners, the above resource configuration information may be a combination of an index and a resource configuration information index table. After the network device sends the resource configuration information to the terminal device, the terminal device obtains the index in the resource configuration information and the resource configuration information index table, and queries the specific resource configuration scheme from the resource configuration information index table according to the above index.

In some possible implementation manners, the network device may encapsulate the above resource configuration information into a downlink signal in a physical downlink control channel (Physical Downlink Channel, PDCCH) in the form of indication bits or signaling messages, and send the downlink signal through the PDCCH to the terminal device.

The above-mentioned downlink signal may be Downlink Control Information (Downlink Control Information, DCI), Media Access Control-Control Element (Media Access Control-Control Element, MAC-CE), Radio Resource Control (Radio Resource Control, RRC) signaling, reference signal One of downlink signals such as indication information.

When the DCI message is used to carry the resource configuration information, additional indication bits may be added to the existing DCI message. The added extra bits may be used to indicate resource configuration information, and may also indicate PoSS signal type, DRX parameters and other information. Alternatively, a new DCI message may also be introduced, and the indication bits in the new DCI message may be used to indicate resource configuration information, and may also indicate PoSS signal type, DRX parameters and other information.

Take the DCI message shown in FIG. 8 as an example. The above DCI message includes N fields, and each field includes several indication bits, one kind of K indication bits. Wherein, both N and K are positive integers.

The indication bits of the above DCI message can be used to indicate resource configuration information, and can also indicate PoSS signal types (such as WUS signal, GTS signal), DRX parameters (such as cycle length of DRX cycle, OnDuration length) and other information.

比特指示资源配置信息，其中，

为上取整符号，L为资源配置信息的总类别数，

比特可以指示L中不同的资源配置信息。As shown in Figure 8, in the above DCI message, the field 3 can be used

Bits indicate resource configuration information, where,

is the upper integer symbol, L is the total number of categories of resource configuration information,

Bits can indicate different resource configuration information in L.

As shown in FIG. 9 , it is assumed that resource configuration information includes the number of CSI measurement reference signals, the period of measurement reference signals, the number of CSI reporting resources, and the period of reporting resources. At this time, the index represented by the indicated bit in field 3 of the DCI is S (0≤S≤L), then the resource configuration information represented by the indicated bit is m _S in the number of CSI measurement reference signals, and the measurement reference signal period is t _S , the number of CSI reporting resources is n _S , and the reporting resource period is p _S .

The above resource configuration information is used to instruct the terminal device to measure and report the channel state information according to the configuration information about the CSI measurement resource and the reporting resource in the resource configuration information.

As shown in FIG. 10 , after receiving the resource configuration information sent by the network device, the terminal device parses the resource configuration information to obtain configuration information about CSI measurement resources and reporting resources. The terminal device uses one or more CSI measurement reference signals to measure the channel state information according to the configuration information of the CSI measurement resources.

After the terminal device completes the measurement of the channel state information, it may perform a reporting operation according to the configuration information of the CSI reporting resource, and feed back the channel state information to the network device through the CSI reporting resource.

The terminal device can encapsulate the CSI into the uplink control information (Uplink Control Information, UCI) in the physical uplink control channel (Physical Uplink ControlChannel, PUCCH), part of the bearer information in the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), etc. .

It should be understood that the sequence numbers of the steps in the above embodiments do not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiment of the present application.
