Title:
APPARATUS AND METHOD OF CHANNEL ACCESS PRIORITY DETERMINATION FOR SIDELINK TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/165702
Kind Code:
A1
Abstract:
Apparatus and methods of channel access priority determination for sidelink transmission are disclosed. The method includes: providing a mapping relationship between PC5 Quality of service (QoS) Indicators (PQIs) and Channel Access Priority Classes (CAPCs), based on delay requirements of the PQIs; and in response to presence of only STCH SDUs from one or multiple SL-DRBs in a SL-MAC PDU for SL transmission to another terminal device, to determine, from the mapping relationship, a corresponding CAPC for the SL-DRB from one or more PQIs from the SL-DRB; and to determine a CAPC for the SL-MAC PDU for SL transmission to the other terminal device, based on the corresponding CAPC of the SL-DRB; in response to presence of SCCH SDUs from one or multiple SL-SRB in the SL-MAC PDU for SL transmission to the other terminal device, to determine a corresponding CPAC of the SL-SRB; and to determine the CAPC for the SL-MAC PDU for SL transmission to the other terminal device, based on at least the corresponding CAPC of the SL-SRB as determined; and in response to presence of only a SL MAC CE for SL transmission to the other terminal device, to determine a corresponding CPAC of the MAC CE; and to determine the CAPC for the SL-MAC PDU for SL transmission to the other terminal device, based on at least the corresponding CAPC of the MAC CE.
