Abstract

The invention relates to the allocation of radio resources by a transmitting user equipment to perform a plurality of direct SL transmissions to one or more receiving user equipments. The allocation of radio resources within a SC period is restricted, for the SC period, by a maximum number of SL processes with which a transmitting user equipment is configured. A plurality of SL grants is acquired. Among the acquired SL grants a number of those SL grants is selected that have most recently been acquired before the start of the subsequent SC period. A plurality of SL processes is associated such that each of the plurality of SL process is associated with a different one of the selected number of SL grants. For each of the plurality of the SL processes, the radio resources are allocated. Each of the plurality of SL transmissions comprises at least one SCI transmission and at least one data transmission over the SL interface.
