    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with a service, the configuration indicating a first set of one or more parameters for accessing the service in a multicast mode using non-access stratum (NAS)-based signaling, and a second set of one or more parameters for accessing the service in a broadcast mode within a broadcast service area. The UE may receive information associated with the service using one of the multicast mode or the broadcast mode. The UE may switch to receiving information associated with the service using the other of the multicast mode or the broadcast mode based at least in part on the first set of one or more parameters or the second set of one or more parameters. Numerous other aspects are described.

    摘要: Methods, systems, and apparatuses for use in wireless communication are disclosed. A method of communication on an unlicensed band may include detecting a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block comprising a demodulation references signal (DMRS), a synchronization signal (SS), and a PBCH payload. A SS/PBCH block index may be obtained from one of the DMRS and the PBCH payload. A cyclic rotation indicator may be obtained from the SS/PBCH block (e.g., from the DMRS, the SS, and/or the PBCH payload). A determination may be made that the cyclic rotation indicator indicates an on state and a time gap may be obtained from one of the DMRS and the PBCH payload, based on the determination. Frame timing may be determined based on the cyclic rotation indicator, the SS/PBCH block index, and the time gap.

    摘要: Support for hybrid automatic repeat request acknowledgment feedback for multiple multicast services in 5G new radio (NR) is provided. Resource allocation techniques are provided to allocate uplink control channel resource for acknowledgment of downlink multicast data transmissions associated with one or more multicast services. An apparatus, such a user equipment (UE), receives multicast data associated with one or more multicast services from a base station. The apparatus determines an uplink resource, such as a physical uplink control channel (PUCCH) resource, for transmitting multicast acknowledgement feedback, such as positive acknowledgement (ACK)/negative acknowledgement (NACK) feedback, in response to the received multicast data. The apparatus transmits the acknowledgement feedback for the one or more multicast services to the base station in the determined uplink resource.

    摘要: Disclosed are a method and device for transmitting or receiving hybrid automatic repeat and request acknowledgement (HARQ-ACK) information in a wireless communication system. A method for a terminal to transmit HARQ-ACK information in a wireless communication system according to an embodiment disclosed herein may comprise the steps of: receiving, from a network, a first multicast physical downlink shared channel (PDSCH) based on a first multicast downlink control indicator (DCI) format; receiving, from the network, a second multicast PDSCH based on a second multicast DCI format; and multiplexing first HARQ-ACK information on the first multicast PDSCH with second HARQ-ACK information on the second multicast PDSCH, and transmitting the multiplexed information to the network through a physical uplink control channel (PUCCH), wherein the second multicast DCI format is received after the first multicast DCI format is received, and the PUCCH resource is determined using the first multicast DCI format.
