Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

FIG. 1 is an application environment diagram of a method for switching a partial bandwidth BMP in one embodiment. As shown in FIG. 1 , the method for switching a partial bandwidth BMP provided by the embodiment of the present invention can be applied to the schematic diagram of the architecture of a wireless communication system as shown in FIG. 1 . The wireless communication system may include network equipment and terminal equipment, wherein , the network equipment may include core network equipment and base stations. The terminal device may include a mobile phone, a tablet computer, a PDA (Personal Digital Assistant, personal digital assistant), a vehicle-mounted computer, a wearable device, and the like.

The terminal device will switch the BWP according to the instructions issued by the network device. The currently configured bandwidth of the terminal device may not meet the requirements of the terminal device, resulting in increased power consumption of the terminal device, or affecting the data transmission rate. For example, at the first moment, the terminal device is downloading the game installation package file and needs a higher rate. At this time, the network device can configure a BWP with a large bandwidth for the terminal device; at the second moment, the terminal device is playing an online game, and the required traffic At this time, the network device configures a BWP with a small bandwidth for the terminal device to meet the upstream and downstream rate requirements of the game; at the third moment, the network device finds that the bandwidth where BWP1 is located has encountered a strong sudden external interference, the signal quality deteriorates sharply, and the terminal equipment cannot meet the Internet access needs. You can urgently configure a new bandwidth for the terminal equipment. When the terminal switches from the first bandwidth to the second bandwidth, there will be a BWP switching delay. The protocol stipulates that the network cannot schedule the uplink and downlink data within the BWP switching delay when scheduling across BWPs. Otherwise, the terminal can be regarded as an error condition. . For example, during the downlink process, BWP1 switches to BWP2, and the DCI of BWP1 schedules the PDSCH (Physical Downlink Shared Channel) physical downlink shared channel on BWP2, which can be divided into the following two situations:

(1) If the PDSCH block is not in the BWP switching delay and has exceeded the BWP switching delay, the terminal will receive the PDSCH block, as shown in FIG. 2 .

(2) If the PDSCH block is in the BWP switching delay and has not exceeded the BWP switching delay, the terminal ignores the PDSCH block, resulting in the need to retransmit the PDSCH block, as shown in FIG. 3 .

The base station in FIG. 1 can configure the first part of the bandwidth BWP for the terminal device. When working in the first BWP, the terminal can obtain the first BMP delay capability reported in history; based on the first BMP delay capability, the BWP switching delay capability is reduced is the second BMP delay capability, and the maximum switching delay corresponding to the second BMP delay capability is greater than the maximum switching delay corresponding to the first BMP delay capability; sending the registration information carrying the second BMP delay capability to the network end middle network equipment, so that the network equipment modifies the network delay capability corresponding to the terminal to the second BMP delay capability, thereby reducing the terminal capability and reporting it to the network, so that the network can lengthen the interval between the scheduling and switching BWP processes, In this way, data scheduling is prevented from occurring within the BWP handover delay, and the stability of the BWP handover is enhanced.

FIG. 4 is a flowchart of a method for switching a partial bandwidth BMP in one embodiment. The method for switching a partial bandwidth BMP shown in FIG. 4 can be applied to the above-mentioned terminal equipment, including:

Step 202: Obtain the first BMP delay capability reported in history.

Among them, the BMP delay capability is used to indicate the maximum handover delay that the terminal meets during BWP handover. Different BMP delay capabilities correspond to different maximum switching delays.

Specifically, the terminal generally supports a variety of different BMP delay capabilities. According to the specification of the 3GPP protocol, if the terminal supports it, BWP partial bandwidth switching can be performed based on DCI downlink control information and timer timing, and BWP switching can also be performed based on RRC (Radio Resource Control, radio resource control). To perform partial bandwidth switching of BWP based on DCI, the network directly delivers DCI to notify the terminal to switch to the target BWP. To perform partial bandwidth switching of BWP based on the timer, the terminal starts the timer and returns to the default BWP after expiration.

For BWP partial bandwidth switching based on DCI downlink control information and timer timing, the protocol specifies the switching delay that the terminal must meet as shown in the table below. The terminal can support Type1 or Type2, and notify the network when the network queries its capabilities.

NR Slot length represents the scheduling unit of the 5G (NR) network standard, BWP switch delayT _{BWPswitchDelay} (slots) represents the maximum delay allowed during BWP switching (unit is slot), type1 and type2 are the two defined modes, if the terminal supports type1 , the network will transmit according to type1, and if the terminal supports type2, the network will transmit according to type2. For example, when μ is 1 and the terminal supports type1, the network knows that the maximum switching delay of the BWP is 2ms, so the PDSCH can be scheduled after 2ms.

The terminal is configured with a supported delay capability mode when it leaves the factory. If the terminal supports a variety of different BMP delay capabilities, it can report the target BMP delay capability to the network according to the situation. If the terminal supports type1 or type2, the historically reported The first BMP delay capability may be type1 or type2.

Step 204: Reduce the BWP switching delay capability to a second BMP delay capability based on the first BMP delay capability, where the maximum switching delay corresponding to the second BMP delay capability is greater than the maximum switching delay corresponding to the first BMP delay capability .

Specifically, when the following situations occur, the actual BWP switching delay of the terminal is relatively large, and it is easy for data scheduling to occur within the BWP switching delay.

Due to terminal software and hardware problems, the terminal cannot actually report the situation. For example, the terminal reports that it supports type 1, but cannot meet the type 1 index requirements due to device aging or other reasons. The network is configured according to the normal delay, but the terminal performance is difficult to meet. The terminal performance meets the type 1 or type 2 requirements reported by itself, but due to network problems, the network configuration does not meet the protocol requirements, so that the DCI and PDSCH scheduled across delays are very close.

When the actual handover delay caused by the above situation is relatively large, the problem can be eliminated as much as possible by gradually reducing the BMP delay capability reported by the terminal. If the terminal historically reports the first BMP delay capability, the BWP switching delay capability is reduced to the second BMP delay capability, where the maximum switching delay corresponding to the second BMP delay capability is greater than that corresponding to the first BMP delay capability Maximum switching delay. If the first BMP delay capability reported by the terminal in the history is type1, the BWP handover delay capability can be reduced to type2.

Step 206: Send the registration information carrying the second BMP delay capability to the network end, so that the network end modifies the network delay capability corresponding to the terminal to the second BMP delay capability.

Specifically, the registration process is triggered to report the updated BMP delay capability to the network, and the terminal sends a registration request (SA) registration request or TAU request (LTE) or Attach request (LTE) to the network, and expects a response from the network. Send the registration information carrying the second BMP delay capability to the network end, so that the network end modifies the network delay capability corresponding to the terminal to the second BMP delay capability, and the subsequent network end passes the updated second BMP delay capability and terminal for data exchange.

In the method for switching partial bandwidth BMPs in this embodiment, the first BMP delay capability reported in the history is obtained, and the BWP switching delay capability is reduced to the second BMP delay capability based on the first BMP delay capability. The maximum switching delay corresponding to the delay capability is greater than the maximum switching delay corresponding to the first BMP delay capability; the registration information carrying the second BMP delay capability is sent to the network end, so that the network end can compare the network delay corresponding to the terminal The capability is modified to the second BMP delay capability. By reducing the terminal BMP delay capability and reporting it to the network, the network can lengthen the interval between the scheduling and the BWP switching process, thereby preventing data scheduling from occurring within the BWP switching delay. Improves the stability of BWP switching.

In one embodiment, before step 204 , the method further includes: acquiring the number of times the uplink and downlink data are scheduled within the BWP handover delay; if the number of times is greater than a preset threshold, enter step 204 .

Specifically, the preset threshold can be customized as needed. Suppose the preset threshold is set to 3 times in 1 minute, then the actual switching delay of 3 times in 1 minute is large, and the capacity will be reduced. If only 2 times in 1 minute occur. times, then the ability will not be reduced.

In this embodiment, by setting a preset threshold, the step of reducing the BMP delay capability will be entered only when the number of uplink and downlink data scheduling within the BWP switching delay is greater than the preset threshold, so as to avoid the actual switching delay due to accidental reasons. Large and direct reduction capability improves the stability of BMP delay capability adjustment.

In one embodiment, as shown in FIG. 5 , after step 206 , the method further includes: .

Step 206A: Acquire information of the target cell to which the terminal currently belongs, and establish an association relationship between the terminal, the information of the target cell and the second BMP delay capability.

Specifically, if the reduction of the BWP handover delay capability occurs in the target cell to which it currently belongs, the terminal records the correlation between the target cell information and the reduced second BMP delay capability, thereby recording each occurrence of the The relationship between the cell with reduced BWP handover delay capability and the target BMP delay capability. If the terminal reduces the BWP handover delay capability from the first BMP delay capability to the second BMP delay capability in cell A, the association between cell A and the second BMP delay capability is recorded.

Step 206B, when it is detected that the terminal enters the cell corresponding to the target cell information from another cell, the step of sending the registration information carrying the second BMP delay capability to the network is entered.

Specifically, when it is detected that the terminal enters the cell corresponding to the target cell information from another cell again, the terminal needs to be restored to the historically recorded target BMP delay capability corresponding to the target cell. If the terminal enters cell A from another cell again and finds that the BMP delay capability corresponding to the terminal in cell A is the second BMP delay capability, it sends the registration information carrying the second BMP delay capability to the network, so that the Notify the network end that the BMP delay capability of the terminal in cell A is the second BMP delay capability. For example, the terminal itself supports type1, has not been to cell A before, but has been to cell B, and the BMP delay capability is reduced to type2. Then the next time the terminal arrives at cell A, it uses the capability of type 1; the next time it arrives at cell B, it uses the capability of type 2.

In this embodiment, the cells whose BMP delay capability has been reduced and the degree to which the capability needs to be reduced are recorded. After entering these cells again, the capability is directly reduced to the target BMP delay capability recorded in the previous association relationship, and the reduction is restored after arriving in other cells. The previous original capability makes it possible to quickly and adaptively adjust the BMP delay capability corresponding to the terminal according to the recorded relationship between the cell and the BMP delay capability, which is efficient and reliable.

In one embodiment, after step 206, the method further includes: obtaining timing information; if the switching duration corresponding to the timing information arrives, sending a delay capability recovery request to the network, and the delay capability recovery request carries the BMP before the delay capability switching Delay capability information, so that the network side modifies the network delay capability corresponding to the terminal to the BMP delay capability before handover.

Specifically, the switching duration corresponding to the timing information can be customized as needed, for example, it is defined as 5 hours, because the actual switching delay of the terminal may be caused by unstable factors, and it may be recovered within a certain period of time. Therefore, the effective timer is set through the timing information, and the original BWP switching delay capability of the terminal is restored after expiration, and the BMP delay capability information before the delay capability switching is carried in the delay capability recovery request to Make the network end modify the network delay capability corresponding to the terminal to the BMP delay capability before handover.

In this embodiment, through the timing information, when the handover duration corresponding to the timing information arrives, the BWP handover delay capability corresponding to the terminal can be automatically restored to the BMP delay capability before the reduction, so as to achieve an adaptive recovery capability.

In one embodiment, step 204 includes: if the first BMP delay capability is a capability of supporting BWP switching based on DCI downlink control information and timer, and is a BWP switching delay first mode capability, then the second BMP The delay capability is the capability to support switching of BWP based on DCI and timer, and is the capability of BWP switching delay second mode, the maximum switching delay corresponding to the BWP switching delay second mode capability is greater than the BWP switching delay first The maximum switching delay corresponding to the mode capability; if the first BMP delay capability is the capability to support switching BWP based on DCI and timer, and the second mode capability is the BWP switching delay, then the second BMP delay capability is disabled based on DCI and timer. The ability of timer to switch BWP.

Specifically, if the BWP handover delay capability previously reported by the terminal is type1, the BWP handover delay capability is reduced to type2, and a registration process is triggered to report the capability change to the network. Otherwise, if the BWP switching delay capability previously reported by the terminal is type 2, the BWP switching capability based on DCI and timer is disabled. That is to say, the terminal capabilities are divided into "the ability to support switching BWP based on DCI and timer, BWP switching delay capability type1", "the ability to support switching BWP based on DCI and timer, BWP switching delay capability type2", "not support Based on the three levels of DCI and timer switching BWP ability, when the actual switching delay is large, gradually try to reduce the ability to solve the problem.

It can be understood that in addition to the BWP handover based on DCI and timer, there is also a BWP handover based on RRC. The BWP handover based on RRC also requires time delay. method, up to close the RRC-based BWP handover capability, if both "RRC-based BWP handover capability" and "BWP handover based on DCI and timer" are turned off, the terminal does not support BWP handover, that is, the terminal only supports 1 BWP .

In this embodiment, by gradually trying to reduce the capability to solve the problem that the actual handover delay of the terminal is relatively large, it is possible to adaptively adjust to an appropriate handover delay capability.

In a specific embodiment, the method for switching a partial bandwidth BMP provided by the embodiment of the present application is described, including the following steps:

1. Obtain the first BMP delay capability reported in the history, and obtain the number of times the uplink and downlink data are scheduled within the BWP switching delay, and if the number of times is greater than the preset threshold, go to the next step.

2. If the first BMP delay capability is the capability of supporting BWP switching based on DCI downlink control information and timer, and is type1, then the second BMP delay capability is the capability of supporting BWP switching based on DCI and timer, and is type2. If the first BMP delay capability is the capability of supporting switching of BWPs based on DCI and timer, and is type 2, the second BMP delay capability is the capability of disabling BWP switching based on DCI and timer.

3. Send the registration information carrying the second BMP delay capability to the network end, so that the network end modifies the network delay capability corresponding to the terminal to the second BMP delay capability.

4. Acquire the information of the target cell to which the terminal currently belongs, and establish an association relationship between the terminal, the information of the target cell and the second BMP delay capability.

5. When it is detected that the terminal enters the cell corresponding to the target cell information from another cell, the step of sending the registration information carrying the second BMP delay capability to the network is performed.

6. Obtain timing information; if the switching duration corresponding to the timing information arrives, send a delay capability recovery request to the network, and the delay capability recovery request carries the BMP delay capability information before the delay capability switch, so that the network can The network delay capability corresponding to the terminal is modified to the BMP delay capability before handover.

7. When it is detected that the terminal enters other cells from the target cell, the network delay capability corresponding to the recovery terminal is the BMP delay capability before handover.

In this embodiment, by reducing the terminal capability and reporting it to the network, the network lengthens the interval between the scheduling and the BWP switching process, thereby preventing data scheduling from occurring within the BWP switching delay, and enhancing the stability of the BWP switching. And set the preconditions, and only use this scheme when the number of uplink and downlink data scheduling within the BWP handover delay exceeds a preset threshold within a period of time, and includes a recording function to record the cells with problems and the degree of capacity reduction. After entering the cell, the capability is directly reduced to this level, and the original capability is restored after arriving in other cells, and a valid timer is also set to restore the original capability after expiration, so that the terminal can dynamically adjust the BMP delay capability according to various situations.
