1. A transmitting user equipment comprising:
a receiver, which, in operation, receives, for a subsequent sidelink control (SC) period, a plurality of sidelink (SL) grants for allocating radio resources to perform a plurality of direct SL transmissions over a SL interface to one or more receiving user equipments in a communication system, before a start of the subsequent SC period, wherein:
the transmitting user equipment is configured with a maximum number of SL processes, and each of the plurality of SL grants is associated with one of the maximum number of SL processes in a one-to-one manner, and
for one of the maximum number of SL processes, a second SL grant received in subframe n for the subsequent SC period overwrites a first SL grant previously received in subframe n-X for the same subsequent SC period, wherein X is an integer value equal to or greater than the maximum number of SL processes;
circuitry, which is coupled to the receiver and which, in operation,
associates the maximum number of SL processes with the plurality of SL grants, respectively, and
allocates, for each of the maximum number of SL processes, radio resources within the subsequent SC period according to the associated SL grant; and
a transmitter, which is coupled to the circuitry and which, in operation, performs the plurality of SL transmissions including at least one sidelink control information (SCI) transmission and at least one data transmission, using the allocated radio resources.
