Detailed Description
As described in the background art, for a newly introduced SCell BFR MAC CE, when uplink transmission is performed in a PCell, since the SCell BFR MAC CE shares PUSCH resources with an existing MAC CE and uplink data of a UE, it is necessary to group a packet in a media access layer protocol data unit (MAC PDU), and how to set a priority of the SCell BFR MAC CE is a problem to be solved.
The inventor of the application finds that the priority relationship of the SCell BFR MAC CE with other MAC CEs and logical channel data needs to be considered in advance. If the priority of the SCell BFR MAC CE is set to be at least higher than the uplink data priority, the functions of other MAC CEs may be affected or may not be applicable in some uplink data traffic scenarios, such as traffic scenarios of high-reliability low-delay communication. In addition, uplink Data has various forms, including Signaling Radio Bearer (SRB) and Data Radio Bearer (DRB), and if SCell BFR MAC CE is set to have higher priority than SRB0, Radio Resource Control (RRC) message transmission may be affected, especially during cell handover or RRC reestablishment. If different service scenarios, such as URLLC scenario, are considered, setting SCell BFR MAC CE to have higher priority than uplink data, prioritizing transmission of SCell BFR MAC CE may result in increased URLLC service delay. The priority relationship between the SCell BFR MAC CE and other MAC CEs needs to be considered, and different influences may occur in different scenarios. For example, setting SCell BFR MAC CE with higher priority than non-filled MAC CE for Buffer Status Report (BSR) in URLLC scenario results in delay of BSR message for URLLC transmission, and further increases URLLC traffic delay. Considering some special cases, the priority order of the SCell BFR MAC CE also needs to be adjusted, for example, the UE finds that the SCell carries data transmission of a logical channel, at this time, there is a BSR to report on the logical channel, and meanwhile, the SCell has a BFR MAC CE to upload. In this scenario, reporting the BSR may not enable the UE to quickly transmit data to be transmitted, and the SCell needs to be recovered first, so that the SCell BFR MAC CE needs to be preferentially transmitted.
In the technical scheme of the invention, the priority of the MAC CE recovered by the failure of the beam of the auxiliary cell can be determined, namely the priority of the MAC CE is given to the SCell BFR; for uplink data and/or MAC CE for BSR which need to be transmitted, the priority of a logic channel where the data which need to be transmitted is located is considered, and the transmission sequence of the MAC CE, the uplink data and/or the MAC CE for BSR which are recovered due to the failure of the beam of the secondary cell can be determined by comparing the multiple priorities, so that the user equipment can transmit the data according to the transmission sequence, the user equipment can report the BFR information of the SCell in the PCell in time to help the communication recovery of the SCell, meanwhile, the influence on the existing service transmission is reduced, the unnecessary control signaling overhead and data retransmission are reduced, the power consumption of the terminal is reduced, the network function can be optimized, and the influence on the existing system is minimized. In addition, the transmission sequence is determined by adopting a mode of dynamically comparing priorities, so that the report of the MAC CE for the auxiliary cell beam failure recovery is more flexible, and the requirement of a multi-service scene is met.
The technical scheme of the invention can be applied to 5G (5Generation) communication systems, 4G and 3G communication systems, and various future new communication systems such as 6G and 7G.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a method for recovering MAC CE transmission in secondary cell beam failure according to an embodiment of the present invention.
The method for transmitting the secondary cell beam failure recovery MAC CE may be used at a User Equipment (UE) side, that is, the User Equipment may perform each step of the method shown in fig. 1.
The method for recovering MAC CE transmission by secondary cell beam failure can comprise the following steps:
step S101: when the MAC CE is recovered due to the failure of reporting the beam of the auxiliary cell, determining the priority of the MAC CE recovered due to the failure of the beam of the auxiliary cell;
step S102: if uplink data and/or MAC CE for BSR which need to be transmitted exist, determining the priority of the uplink data and/or MAC CE for BSR;
step S103: comparing the priority of the MAC CE for the beam failure recovery of the secondary cell with the priority of the uplink data and/or the MAC CE for BSR to determine a transmission sequence;
step S104: and recovering the MAC CE and the uplink data and/or the MAC CE for BSR according to the transmission sequence after the auxiliary cell beam is uploaded.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.
The ue in this embodiment is a ue using Carrier Aggregation (CA), and is connected to a primary base station and a secondary base station, and the ue is located in a primary cell PCell and a secondary cell SCell.
In the specific implementation of step S101, the UE detects that the secondary cell SCell has a beam failure, and the UE in the primary cell PCell needs to report the SCell BFR MAC CE to help the secondary cell SCell perform beam recovery. The UE may now determine the priority of the SCell BFR MAC CE. For example, the priority of the SCell BFR MAC CE is K.
In an embodiment of the present invention, step S101 shown in fig. 1 may include the following steps: if the transmitted data exists in the secondary cell, determining the highest priority of the priorities of the logical channels of all the transmitted data as the priority of the MAC CE for the beam failure recovery of the secondary cell; and if the transmitted data does not exist in the secondary cell, determining the highest priority of the priorities of the logical channels of all the data to be transmitted as the priority of the beam failure recovery MAC CE of the secondary cell.
In this embodiment, the UE may traverse the priorities of all logical channels of the data being transmitted, and select the highest priority as the priority of the SCell BFR MAC CE. Or, the UE may also traverse the priorities of all logical channels with data to be transmitted, and select the highest priority as the priority of the SCell BFR MAC CE. Or, under the condition that the data being transmitted exists, selecting the highest priority in the logical channels of all the data being transmitted as the priority of the SCell BFR MAC CE; otherwise, selecting the highest priority of all the logic channels with the data to be transmitted as the priority of the SCell BFR MAC CE.
The method and the device determine the priority of the MAC CE for the auxiliary cell beam failure recovery according to the priority of the logical channel of the data being transmitted, and determine the priority of the MAC CE for the auxiliary cell beam failure recovery according to the priority of the logical channel of the data to be transmitted under the condition that the data being transmitted does not exist, so that the accuracy of determining the priority of the MAC CE for the auxiliary cell beam failure recovery is ensured.
With continued reference to fig. 1, the UE may have other data to transmit in addition to the SCell BFR MAC CE. Such as uplink data and/or MAC CE for BSR. Therefore, in step S102, for the case that there is uplink data and/or MAC CE for BSR that needs to be transmitted, the UE may determine the priority of the uplink data and/or MAC CE for BSR.
Specifically, the UE may determine the priority of the uplink data according to the priority of the logical channel for transmitting the uplink data; the UE may set the priority of the MAC CE for BSR according to the highest priority of the logical channel of the to-be-transmitted service in the cell where the data service is transmitted corresponding to the BSR in the MAC CE for BSR.
Further, in step S103, the UE may compare the sizes of the priorities of the SCell BFR MAC CE and the uplink data and/or MAC CE for BSR to determine a transmission order of the SCell BFR MAC CE and the uplink data and/or MAC CE for BSR. The higher the priority is, the earlier the ranking is, and the earlier the ranking is reported to the base station in the subsequent steps.
The transmission sequence may refer to a transmission sequence in which the UE transmits the SCell BFR MAC CE and the uplink data and/or MAC CE for BSR when reporting the SCell BFR MAC CE and the uplink data and/or MAC CE for BSR to the base station.
For example, when the SCell BFR MAC CE and the uplink data need to be transmitted simultaneously, the priority of the SCell BFR MAC CE is higher than the priority of the uplink data, and the transmission order may be the SCell BFR MAC CE and the uplink data, that is, the UE transmits the SCell BFR MAC CE first and then transmits the uplink data.
Further, in step S104, the UE may upload the uplink data and/or MAC CE for BSR and uplink data and/or MAC CE for recovery MAC CE and uplink data and/or MAC CE for BSR according to the transmission sequence.
In the embodiment of the invention, the priority of the MAC CE recovered by the beam failure of the secondary cell can be determined, namely the priority of the MAC CE is given to the SCell BFR; for uplink data and/or MAC CE for BSR which need to be transmitted, the priority of a logic channel where the data which need to be transmitted is located is considered, and the transmission sequence of the MAC CE, the uplink data and/or the MAC CE for BSR which are recovered due to the failure of the beam of the secondary cell can be determined by comparing the multiple priorities, so that the user equipment can transmit the data according to the transmission sequence, the user equipment can report the BFR information of the SCell in the PCell in time to help the communication recovery of the SCell, meanwhile, the influence on the existing service transmission is reduced, the unnecessary control signaling overhead and data retransmission are reduced, the power consumption of the terminal is reduced, the network function can be optimized, and the influence on the existing system is minimized. In addition, the transmission sequence is determined by adopting a mode of dynamically comparing priorities, so that the report of the MAC CE for the auxiliary cell beam failure recovery is more flexible, and the requirement of a multi-service scene is met.
In one non-limiting embodiment of the present invention, step S102 shown in fig. 1 may include the following steps: and determining the priority of the logical channel for transmitting the uplink data as the priority of the uplink data.
In this embodiment, the UE needs to upload uplink data and the SCell BFR MAC CE at the same time. In this case, the UE may determine the priority of the logical channel currently transmitting the uplink data as the priority of the uplink data. The uplink data may be uplink data in the PCell.
Further, if the priority of the uplink data is higher than the priority of the secondary cell beam failure recovery MAC CE, the transmission order is determined to be that the uplink data is transmitted first and then the secondary cell beam failure recovery MAC CE is transmitted.
In this embodiment, if the priority of the uplink data is higher than the priority of the SCell BFR MAC CE, it indicates that the UE is in a scenario where the priority of the uplink service of the main base station is higher, so that the uplink data can be preferentially transmitted, the service requirement of the main base station is met, and the user experience is ensured.
On the contrary, if the priority of the uplink data is not higher than the priority of the SCell BFR MAC CE, it indicates that the UE is in a normal service scenario, so the SCell BFR MAC CE may be transmitted preferentially to recover the transmission service of the secondary cell as soon as possible.
In one non-limiting embodiment of the present invention, step S102 shown in fig. 1 may include the following steps: determining a cell where a data service corresponding to the BSR in the MAC CE for BSR is transmitted; and determining that the highest priority of the priorities of the logical channels of the services to be transmitted in the cell is the priority of the MAC CE for BSR.
In this embodiment, the UE needs to upload the MAC CE for BSR and the SCell BFR MAC CE at the same time. In this case, the UE may determine a cell where the data service to be transmitted corresponding to the BSR is located, and then determine that the highest priority of the priorities of the logical channels of the service to be transmitted in the cell is the priority of the MAC CE for BSR.
Further, if the priority of the MAC CE for BSR is higher than the priority of the secondary cell beam failure recovery MAC CE, determining that the transmission order is to transmit the MAC CE for BSR first and then transmit the secondary cell beam failure recovery MAC CE.
In this embodiment, the MAC CE for BSR carries the buffer status report, and if the priority of the MAC CE for BSR is higher than the priority of the SCell BFR MAC CE, the MAC CE for BSR needs to be transmitted preferentially, so that the base station can obtain the buffer status report as soon as possible.
On the contrary, if the priority of the MAC CE for BSR is not higher than the priority of the SCell BFR MAC CE, the SCell BFR MAC CE may be preferentially transmitted to recover the transmission service of the secondary cell as soon as possible.
In a non-limiting embodiment of the present invention, referring to fig. 2, step S103 shown in fig. 1 may include the following steps:
step S201: if the priority of the uplink data is higher than the priority of the auxiliary cell beam failure recovery MAC CE, determining the transmission sequence as that the MAC CE for BSR is transmitted first, then the uplink data is transmitted, and finally the auxiliary cell beam failure recovery MAC CE is transmitted;
step S202: if the priority of the uplink data is not higher than the priority of the MAC CE for the failure recovery of the beam of the auxiliary cell, comparing the priority of the MAC CE for BSR with the priority of the MAC CE for the failure recovery of the beam of the auxiliary cell;
step S203: if the priority of the MAC CE for BSR is higher than the priority of the MAC CE for the failure recovery of the beam of the secondary cell, determining the transmission sequence as that the MAC CE for BSR is transmitted first, then the MAC CE for the failure recovery of the beam of the secondary cell is transmitted, and finally the uplink data is transmitted;
step S204: and if the priority of the MAC CE for BSR is not higher than the priority of the MAC CE for the failure recovery of the beam of the secondary cell, determining the transmission sequence as that the MAC CE for the failure recovery of the beam of the secondary cell is transmitted first, then the MAC CE for BSR is transmitted, and finally the uplink data is transmitted.
In this embodiment, the UE needs to upload uplink data, MAC CE for BSR and SCell BFR MAC CE at the same time.
This embodiment specifically describes a comparison method of priorities of uplink data, MAC CE for BSR and SCell BFR MAC CE. For determining the priority of the uplink data, the MAC CE for BSR, and the SCell BFR MAC CE, reference may be made to the foregoing embodiments, which are not described herein again.
In specific implementation, the priority of uplink data is compared with the priority of the SCell BFR MAC CE; and under the condition that the priority of the uplink data is not higher than that of the SCell BFR MAC CE, comparing the priority of the SCell BFR MAC CE with the size of the MAC CE for BSR to finally determine the transmission sequence of the uplink data, the SCell BFR MAC CE and the MAC CE for BSR.
That is, since the position of the uplink data in the transmission order is located after the position of the MAC CE for BSR in the transmission order, it may be determined first whether the position of the uplink data in the transmission order is located before or after the position of the SCell BFR MAC CE in the transmission order, and then whether the position of the SCell BFR MAC CE in the transmission order is located before or after the position of the MAC CE for BSR in the transmission order.
