Abstract
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS), wherein the configuration, which is specific to the UE, identifies allocated resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions; and use the allocated resources identified in the configuration for the HARQ retransmissions. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS),
- wherein the configuration, which is specific to the UE, identifies allocated resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions;
- and
- using the allocated resources identified in the configuration for the HARQ retransmissions.
A method of wireless communication performed by a base station, comprising:
- selecting a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS) for a user equipment (UE), based at least in part on parameters associated with the UE, by allocating resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions;
- and
- transmitting the configuration to the UE.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- receive a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS),
- wherein the configuration, which is specific to the UE, identifies allocated resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions;
- and
- use the allocated resources identified in the configuration for the HARQ retransmissions.
A base station for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- select a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS) for a user equipment (UE), based at least in part on parameters associated with the UE, by allocating resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions;
- and
- transmit the configuration to the UE.
