Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a network node, one or more semi-persistent scheduling (SPS) configurations that configure multiple SPS occasions. The mobile station may receive, from the network node, a retransmission of a data packet in an unused SPS occasion, of the multiple SPS occasions. Numerous other aspects are described.
Claims17
A mobile station for wireless communication, comprising:
- one or more memories;
- and
- one or more processors that, based at least in part on information stored in the one or more memories, are configured to:
- receive, from a network node, one or more semi-persistent scheduling (SPS) configurations that configure multiple SPS occasions;
- receive, from the network node, a retransmission of a data packet in a skipped SPS occasion of the multiple SPS occasions;
- and
- receive, from the network node and in the skipped SPS occasion, downlink control information (DCI) piggybacked on the retransmission to indicate that the data packet is being retransmitted in the skipped SPS occasion.

- and
- receive, from the network node, a retransmission of a data packet in a skipped SPS occasion of the multiple SPS occasions,
- wherein a cyclic redundancy check of the data packet is scrambled with a scrambling sequence, the scrambling sequence indicating that the data packet is a retransmission of a previously transmitted data packet.
