Section: 5.20 Preallocated uplink grant
Content: When the preallocated uplink grant is configured by RRC, the following information is provided in ul-ConfigInfo: - Uplink Scheduling interval ul-SchedInterval, starting subframe ul-StartSubframe of the preallocated uplink grant, the uplink grant ul-Grant and the number of HARQ process for the preallocated uplink grant numberOfConfUL-Processes. When the preallocated uplink grant configuration is released by RRC, the corresponding preallocated uplink grant shall be discarded. NOTE 1: When eIMTA is configured for the SpCell, if a preallocated grant occurs in a subframe that can be reconfigured through eIMTA L1 signalling, then the UE behaviour is left unspecified. If ul-ConfigInfo is configured, the MAC entity shall: - consider sequentially that the Nth grant occurs in the subframe for which: - subframe = [N * ul-SchedInterval + ul-StartSubframe] modulo 10. For TDD, the MAC entity is configured with ul-SchedInterval shorter than 10 subframes, the Nth grant shall be ignored if it occurs in a downlink subframe or a special subframe. NOTE 2: Retransmissions for uplink transmissions using the preallocated uplink grant can continue after clearing the preallocated uplink grant.
