For the direct communication between traditional terminal, current Sidelink BSR (Buffer State Reporting, Buffer Status Report) report mechanism as follows: network side equipment is that terminal directly configures LCG (Logical Channel Group, logic channel group) and PPPP (ProSe Per-Packet Priority, direct communication packet priority Grade) mapping relations.When terminal has Sidelink BSR to report demand, according to the LC (Logical for having data to transmission Channel, logic channel) PPPP, determine its ownership LCG, then determine the corresponding data volume of each LCG, encapsulate Sidelink BSR MAC CE (media access control layer control unit), and utilize UL nearest after Sidelink BSR triggering Grant (uplink scheduling license), is sent to network for Sidelink BSR information.
If Sidelink supports PDCP (Packet Data Convergence Protocol, packet data convergence association View) repeat function, principle is repeated according to PDCP, configures or have activated the radio bearer SLRB of the direct communication interface of repeat function The data PPPP of corresponding two logic channels is identical, then a LCG will necessarily be corresponded to, according to existing Sidelink BSR MAC CE design method, a LCG only correspond to a BS domain name, then network side scheduling sidelink money When source just can not by (such as different carrier resource) on the data dispatch of the SLRB of repeat function to different physical resources, thus It not can guarantee and obtain duplicate gain.
For Uu link, there is also similar problems, and base station is generally according to QoS (Quality of Service, quality of service) It is divided to carry out radio bearer RB and LCG, then a LCG will be also divided by carrying its corresponding difference LC for repetition, Therefore network side can not identify that a repetition carries the data volume of corresponding multiple logic channels, then network side dispatches Uu uplink It can not be by (such as different carrier resources) on the data dispatch to different physical resources for repeating carrying, to can not protect when resource Card obtains duplicate gain.
