Abstract:
In New Radio, NR, when a SR PUCCH resource to which a triggered SR is mapped overlaps with a PUCCH carrying UCI, such as HARQ-ACK and/or CSI, an indication of the corresponding schedulingRequestID, which determines the logical channel ID with new data, is directly encoded in the UCI. That is, rather than directly transmit the relevant SR PUCCH resource(s), which indirectly identifies the SR ID, an indication of the SR ID is directly transmitted on the PUCCH transmission. The encoding of an indication of SR ID may comprise adding bits to UCI to be transmitted, for PUCCH formats 2, 3, or 4. For PUCCH format 0, encoding the indication of SR ID comprises adding an initial cyclic offset indicating the triggered SR.
