Detailed ways

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings required in the embodiments of the present invention. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort.

In order to facilitate the understanding of the embodiments of the present invention, the following contents are first described.

The unlicensed band (unlicensed band) can be used as a supplement to the licensed band (licensed band) to help operators expand the service. In order to be consistent with New Radio (NR) deployment and maximize NR-based unlicensed access as much as possible, the unlicensed frequency band can work in the 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80MHz or 100MHz) of the unlicensed frequency band can reduce the implementation complexity of the base station and UE. Since the unlicensed frequency band is shared by multiple technologies (RATs), such as WiFi, radar, LTE-LAA, etc., in some countries or regions, the unlicensed frequency band must comply with the regulations when used to ensure that all devices can be used fairly The use of this resource, such as LBT (listen beforetalk), maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT) and other rules. When the transmission node needs to send information, it needs to perform LBT first, and perform power detection (energy detection, ED) on the surrounding nodes. When the detected power is lower than a threshold, the channel is considered to be idle (idle), and the transmission node can perform send. Otherwise, it is considered that the channel is busy, and the transmission node cannot send. The transmission node may be a base station, a UE, a WiFi access point (AccessPoint, AP) and so on. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT.

Among them, the type of LBT (category) can be divided into category 1, category 2 and category4. Category1LBT means that the transmission node does not perform LBT, that is, no LBT or direct transmission (immediate transmission). Category 2LBT is one-shot LBT, that is, the transmission node performs LBT once before transmission. If the channel is empty, it will transmit, and if the channel is busy, it will not transmit. Category 4LBT is a channel monitoring mechanism based on back-off. When the transmission node detects that the channel is busy, it backs off and continues to listen until it detects that the channel is empty. Category 4LBT includes multiple priorities, and for each priority, the maximum channel occupation time is different. As shown in Table 1 and Table 2 below.

Table 1 Channel Access Priority Class (Channel Access Priority Class)

Table 2 Uplink channel access priority

Wherein, T _mcot,p in the above Table 1 represents the maximum channel occupancy time of the downlink transmission corresponding to the priority p. T _ulmcot,p in the above Table 2 represents the maximum channel occupation time of the uplink transmission corresponding to the priority p. m _p represents the coefficient corresponding to the corresponding priority p. CW _p represents the value of the contention window corresponding to the corresponding priority p. CW _min,p represents the minimum value of the contention window corresponding to the corresponding priority p. CW _max,p represents the maximum value of the contention window corresponding to the corresponding priority p.

Various types of physical random access channel (physical random access channel, PRACH) preamble format (PRACH preamble format) are defined in NR. Different formats correspond to different preamble sequence lengths, interval CP lengths, time domain lengths, etc. , adapted to different coverage ranges. Wherein, the total duration of the PRACH in various formats is different. For each PRACH preamble format, the corresponding channel access priority can be agreed upon. For each cell, the network can configure a PRACH preamble format, 64 preamble sequences, 64 preambles corresponding to different cyclic shift values, and the same or different root sequence number values.

A wireless communication system in this embodiment of the present invention includes a terminal and a network device. Wherein, the terminal can also be called terminal equipment or user equipment (UE), and the terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), Terminal-side devices such as mobile Internet devices (Mobile Internet Device, MID), wearable devices (Wearable Devices) or vehicle-mounted devices, it should be noted that the specific types of terminals are not limited in the embodiments of the present invention. The network equipment can be a base station or a core network, wherein the above-mentioned base station can be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access points, etc.), base stations may be referred to as Node B, eNode B, access point, base transceiver station (Base Transceiver Station, BTS), radio base station, radio transceiver, Basic Service Set (Basic Service Set, BSS), Extended Service Set (ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN access point, WiFi node, or some other suitable The term is not limited to specific technical terms as long as the same technical effect is achieved.

Please refer to FIG. 1. FIG. 1 is a flowchart of a resource sharing method provided by an embodiment of the present invention. The method is applied to a terminal. As shown in FIG. 1, the method includes the following steps:

Step 101: Select random access resources.

In this embodiment, the random access resource is used to indicate whether the network device is allowed to share the channel occupancy time (Channel Occupancy Time, COT) of the terminal. Specifically, the random access resource is used to implicitly indicate whether to allow the network device to share the COT of the terminal.

Optionally, the process for the terminal to select random access resources may be: first, determine whether to allow the network device to share its own COT, and obtain a determination result; wherein, the determination result may be to allow the network device to share its own COT or not to allow the network device to share its own COT Share its own COT; then, select a random access resource corresponding to the determination result, where the random access resource implicitly indicates that the network device is allowed or not allowed to share the COT of the terminal. After selecting the random access resource, the terminal can perform random access according to the random access resource.

Optionally, the foregoing random access resource may include any of the following: a random access preamble (preamble), a random access opportunity (RACH occasion, RO), and the like.

In the resource sharing method of the embodiment of the present invention, the selected random access resources are used to indicate whether the network device is allowed to share the COT of the terminal, so that the terminal can implicitly indicate whether to share the COT by using different resources, so that the terminal performing random access can Share your own COT with network devices, thereby reducing the delay in sending information from network devices and improving random access efficiency.

In the embodiment of the present invention, in order to enable the selected random access resources to indicate (implicitly) allow or not allow the network device to share the COT of the terminal, the random access resources can be grouped, and different groups of resources can be selected to indicate whether Conduct COT sharing.

Optionally, when grouping the random access resources, it can be divided into two resource groups, namely the first resource group and the second resource group, respectively representing the COT that allows the network device to share the terminal and that does not allow the network device to share the terminal COT. In this way, if the random access resource belongs to the first resource group, it may indicate that the network device is allowed to share the COT of the terminal; or, if the random access resource belongs to the second resource group, it may indicate that the network device is not allowed to share the terminal. COT.

It can be understood that the "first" and "second" in the above-mentioned first resource group and second resource group are used to distinguish resource groups, and have no specific meaning. The first resource group can also be used under appropriate circumstances. It indicates that the network device is not allowed to share the COT of the terminal, and the second resource group indicates that the network device is allowed to share the COT of the terminal.

In one embodiment, taking the random access resource as preamble as an example, the preamble can be divided into two groups, namely preamble group 1 and preamble group 2, wherein preamble group 1 means that UE allows gNB to share its own COT, and preamble group 2 Indicates that the UE does not allow the gNB to share its own COT. The UE implicitly indicates whether to allow the gNB to share the UE's COT by selecting a preamble in a different group. In this way, when the gNB detects that the UE uses the preamble in preamble group 2, the gNB does not share the COT of the UE. And when the gNB detects that the UE uses the preamble in preamble group 1, the gNB can share the COT of the UE as agreed and send downlink data.

In another implementation, taking the random access resource as RO as an example, RO can be divided into two groups, namely RO Group 1 and RO Group 2, where RO Group 1 means that UE allows gNB to share its own COT, and RO Group 2 indicates that the UE does not allow the gNB to share its own COT. The UE implicitly indicates whether to allow the gNB to share the UE's COT by selecting ROs in different groups. In this way, when the gNB detects that the UE uses the RO in RO group 2, the gNB does not share the COT of the UE. And when the gNB detects that the UE uses the RO in RO group 1, the gNB can share the COT of the UE as agreed and send downlink data.

Optionally, in the case where the foregoing random access resource includes a random access preamble (preamble), different resource groups may be distinguished by any of the following:

different random access preamble (preamble) index;

different cyclic shift values;

Different root ordinals.

Optionally, the grouping manner of the above resource groups may be determined according to any of the following:

1) Predefined rules

Under this 1), the grouping method can be determined implicitly.

For example, taking a preamble as an example, preambles with odd numbers correspond to a resource group, indicating that COT is allowed to be shared, while preambles with even numbers correspond to another resource group, indicating that COT is not allowed to be shared; or, you can also predefine the preamble X( X is an integer greater than 0) preambles correspond to a resource group, which means that COT is allowed to be shared, and the last 64-X preambles correspond to another resource group, which means that COT is not allowed to be shared.

For another example, taking RO as an example, you can predefine that odd-numbered ROs correspond to a resource group, indicating that COT sharing is allowed, while even-numbered ROs correspond to another resource group, indicating that COT sharing is not allowed. In this way, if the gNB detects a PRACH on an odd-numbered RO, it considers that the UE's COT can be shared; or, if the gNB detects a PRACH on an even-numbered RO, it considers that the UE's COT cannot be shared.

2) Instructions for network devices

Under this 2), the grouping method can be explicitly determined.

For example, taking the preamble as an example, the network devices may respectively indicate whether the preamble set corresponding to the COT can be shared.

For another example, taking RO as an example, gNB can explicitly configure which ROs send PRACH preamble to implicitly indicate that gNB can share UE's COT, and which ROs send PRACH preamble to implicitly indicate that gNB cannot share UE's COT.

In the embodiment of the present invention, when the terminal shares its own remaining COT with the network equipment, since the terminal cannot explicitly send COT-related information to the network equipment, such as the priority class of the terminal for LBT, the COT of the terminal, etc. The remaining time (remaining COT), the end time of the COT of the terminal, etc., so the above COT related information can be indicated implicitly through the configured PRACH (Physical Random Access Channel, Physical Random Access Channel) preamble format (PRACH preamble format). Specifically, it may be agreed that each PRACH preamble format corresponds to a channel access priority (priority class value), and this priority is the highest priority allowed to be used by terminals configured with the PRACH preamble format. That is to say, for each PRACH preamble format, the protocol specifies the highest priority of channel access corresponding to it. The channel access priority selected by the terminal during random access cannot be higher than the highest channel access priority corresponding to the configured PRACH preamble format, so that the network device can obtain COT-related information.

Optionally, during random access, the terminal in the embodiment of the present invention may use the corresponding channel access priority to listen to the channel according to the configured PRACH preamble format, and when the detected channel is empty , for random access.

For example, for PRACH preamble format1 or PRACH preamble format2, the highest priority of channel access allowed by the UE is priority class 2; for other PRACH preamble formats, the highest priority of channel access allowed by the UE is priority class 1. Therefore, during random access, if the UE is configured with PRACH preamble format1 or PRACH preamble format2, the priority class that can be used is priority class2, 3 or 4; or, if it is configured with other PRACH preamble formats, it can be used The priority is priority class1, 2, 3 or 4.

Please refer to FIG. 2. FIG. 2 is a flowchart of a resource sharing method provided by an embodiment of the present invention. The method is applied to a network device. As shown in FIG. 2, the method includes the following steps:

Step 201: Determine whether to share the COT of the terminal according to the random access resources used by the terminal.

In this embodiment, the random access resource is used to indicate (implicitly) whether to allow the network device to share the COT of the terminal, and is a resource selected and used by the terminal when performing random access. When the network device detects the resource used by the terminal for random access (such as initial access), based on the content implicitly indicated by the resource, it may decide whether to share the COT of the terminal.

Optionally, the foregoing random access resource may include any of the following: a random access preamble (preamble), a random access opportunity (RO), and the like.

In the resource sharing method of the embodiment of the present invention, the network device can determine whether to share the COT of the terminal according to the resources used by the terminal for random access, so that the network device can send information based on the shared COT of the terminal, thereby reducing the cost of sending information by the network device Delay, improve random access efficiency.

In the embodiment of the present invention, in order to enable the random access resources selected by the terminal to implicitly indicate whether the network device is allowed to share the COT of the terminal, the random access resources can be grouped, and different groups of resources can be used to indicate whether to perform COT shared.

Optionally, when grouping the random access resources, it can be divided into two resource groups, namely the first resource group and the second resource group, respectively representing the COT that allows the network device to share the terminal and that does not allow the network device to share the terminal COT. The above step 201 may include:

If the random access resource belongs to the first resource group, determine to share the COT of the terminal;

Or, if the random access resource belongs to the second resource group, it is determined not to share the COT of the terminal.

Optionally, in the case of determining the COT of the shared terminal, the duration of the COT of the terminal shared by the network device may be a fixed duration, for example, the fixed duration may be stipulated by an agreement; or, determined by the maximum channel occupation time (Maximum Channel Occupancy Time) of the terminal , MCOT) decision, wherein, the sum of the COT duration of the terminal shared by the network device and the PRACH transmission duration of the terminal is less than or equal to (that is, not exceeding) the duration of the MCOT; for example, the MCOT can be stipulated by the agreement.

For example, in the Future Enhanced Licensed Assisted Access (Further enhanced Licensed Assisted Access, FeLAA) autonomous uplink (Autonomous Uplink, AUL), the COT duration of the UE that the eNB can share does not exceed 2 symbols. In NR-U, the fixed duration of the COT of the UE shared by the gNB can be stipulated in the protocol.

Optionally, in the case of being determined by the terminal MCOT, the duration of the COT of the terminal shared by the network device may be determined by the MCOT obtained according to the highest priority of channel access corresponding to the PRACH preamble format of the terminal For example, it may be determined by the minimum MCOT (minimum MCOT) obtained according to the highest priority, that is, the sum of the transmission duration of the terminal and the duration that the network device can share does not exceed the minimum MCOT duration.

Wherein, the highest priority of channel access corresponding to the above-mentioned PRACH preamble format may be stipulated by a protocol. That is, in the embodiment of the present invention, for each PRACH preamble format, the highest priority of channel access corresponding to it can be stipulated by agreement.

In one embodiment, it is assumed that the gNB configures PRACH preamble format1 for the UE, and the agreement stipulates that the highest priority of channel access corresponding to the PRACH preamble format1 is priority class 2, and the channel access priority table based on the existing uplink UL As shown in Table 2 above, the MCOT corresponding to the priority class 2 is 4ms, that is, the minimum MCOT is 4ms. At this time, even if the UE selects priority class 3 for channel access, the MCOT corresponding to the priority class 3 is 6ms, and the sum of the UE transmission duration and the UE COT duration that can be shared by the gNB is also limited to 4ms. That is, the duration of the COT of the UE shared by the gNB is determined based on 4ms, which is equal to 4ms minus the duration of the corresponding PRACH. In this way, it can be guaranteed that the sum of the UE's transmission time and the gNB's transmission time (shared by the UE) will never exceed the UE's MCOT.

In the embodiment of the present invention, when the network device shares the COT of the terminal, uplink and downlink conversion occurs in the COT of the terminal, that is, from the initial uplink transmission to downlink transmission. In order to meet the requirements of uplink and downlink conversion within the COT, the interval (gap) between the end time of the downlink transmission and the start time of the uplink transmission can be stipulated by the protocol. For example, the gap can be selected to be less than 16us, equal to 16us, or approximately equal to 25us.

Optionally, in the case of determining the COT of the shared terminal, the LBT type used by the network device in the shared COT may be any of the following: type 1, type 2.

Among them, the type 1 (category 1) is direct transmission (immediate transmission), that is, no LBT (no LBT). This type 2 (category 2) is a one-shot LBT (one-shot LBT), which can be selected as type 2 with a preset duration, such as 16us LBT or 25us LBT.

Optionally, the LBT type adopted by the foregoing network devices in the shared COT may be determined according to any of the following:

agreement;

COT implicit indication;

The PRACH preamble format is implicitly indicated.

For example, assuming that the UE is configured with PRACH preamble format1, the PRACH preamble format1 implicitly indicates that the LBT type adopted by the network device is type 1. Alternatively, assuming that the UE is configured with PRACH preamble format2, the PRACH preamble format2 implicitly indicates that the LBT type adopted by the network device is a 16us LBT.
