NON-RANDOM CYCLIC SHIFT SELECTION TO AVOID CYCLIC SHIFT COLLISION FOR SIDELINK CONTROL CHANNEL

Abstract:

A user equipment (UE) transmits a first transmission comprising first sidelink control information (SCI) using a first cyclic shift, where the first SCI includes information about a second cyclic shift of second SCI for a second transmission from the UE. The UE then transmits the second transmission comprising the second SCI using the second cyclic shift. A receiving UE receives, from a second UE, a first transmission comprising first SCI having a first cyclic shift and uses information in the first SCI to determine cyclic shift information about a second cyclic shift of second SCI for a second transmission from the UE. The receiving UE may exclude the second cyclic shift from selection using the information received in the first SCI.
