Abstract
The present disclosure relates generally to the field of wireless communications and, in particular, to techniques for issuing criteria-based retransmission grants for pending Media Access Control (MAC) Protocol Data Units (PDUs) generated and buffered in a user equipment (UE) in a wireless communication network. In particular, the UE is configured with at least one criterion for determining which of the pending MAC PDUs stored in the UE (e.g., in the HARQ buffers) could be transmitted by using radio resources of a retransmission grant issued by a network node. In other words, the UE should determine whether at least one of the pending MAC PDUs meets the at least one criterion. The at least one criterion may be signalled to the UE either in the retransmission grant or independently from the retransmission grant. If none of the pending MAC PDUs meets the at least one criterion, it is also allowed to apply the at least one criterion to a new MAC PDU, thereby making it possible to use the retransmission grant issued by the network node as a new transmission grant (provided that the new MAC PDU meets the at least one criterion). Thus, by using such a retransmission grant, it is possible to provide efficient MAC PDU recovery and resource usage.
