Bandwidth part configurations for V2X communication
摘要
說明書
If a UE 102 is configured by higher layer parameter firstActiveDownlinkBWP-Id with a first active DL BWP and by higher layer parameter firstActiveUplinkBWP-Id a first active UL BWP on a secondary cell or on a supplementary UL carrier, the UE 102 may use the indicated DL BWP and the indicated UL BWP as the respective first active DL BWP on the secondary cell and the first active UL BWP on the secondary cell or the supplementary UL carrier.
For paired spectrum operation, a UE 102 may not expect to transmit a PUCCH with HARQ-ACK information on a PUCCH resource indicated by a DCI format 1_0 or a DCI format 1_1 if the UE 102 changes its active UL BWP on the PCell between a time of a detection of the DCI format 1_0 or the DCI format 1_1 and a time of a corresponding PUCCH transmission with HARQ-ACK information. A UE 102 may not expect to monitor PDCCH when the UE 102 performs RRM measurements over a bandwidth that is not within the active DL BWP for the UE 102.
Transmissions in multiple cells may be aggregated. Unless otherwise noted, the description in this specification applies to each of the serving cells.
Some examples of V2X services are described herein. PSSCH may be used for transmitting sidelink shared channel (SL-SCH). SL-SCH may be the V2X data. As a resource for V2X communication, a resource pool may be defined. A base station (gNB) 160 may transmit information on a configuration of one or more resource pools by system information block(s) (SIB(s)) or dedicated radio resource control (RRC) message(s). A UE 102 may select one resource pool and a resource within a resource pool that is used for PSCCH and/or PSSCH. V2X service may be operated in uplink band(s).
