Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) process number indication for multi-cell scheduling. In some cases, a user equipment (UE) may receive first control signaling including one or more parameters associated with a HARQ process. Additionally, the UE may receive second control signaling indicating scheduling information associated with a set of component carriers (CCs), where the scheduling information includes one or more HARQ process identifier (HPID) offsets, each associated with a respective CC. In some cases, the UE may determine an HPID associated with each CC of the set of CCs based on the one or more parameters in the first control signaling and a respective HPID offset from the one or more HPID offsets in the second control signaling.

Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives a physical downlink control channel (PDCCH) configuration associated with a first radio access technology (RAT), the PDCCH configuration for a first set of time-frequency resources including one or more control channel elements (CCEs). The UE receives a cell-specific reference signal (CRS) configuration associated with a second RAT, the CRS configuration for a second set of time-frequency resources that overlaps with at least one CCE. The UE receives a demodulation reference signal (DMRS) within a third set of time-frequency resources of a PDCCH in accordance with a DMRS configuration that is identified for the third set of time-frequency resources based on the PDCCH configuration and the CRS configuration, the third set of time-frequency resources included within the one or more CCEs of the first set of time-frequency resources exclusive of the second set of time-frequency resources.

Abstract: Aspects are provided which allow a UE to apply power-efficient UCI multiplexing rules accounting for situations in which CCs of overlapping PUCCH and PUSCH are in different carrier groups during inter-band CA to result in improved transmission performance. The UE transmits UCI in a PUCCH in a first CC in response to the PUCCH overlapping in time with a PUSCH in a second CC and the first CC being associated with a different carrier group than the second CC. Alternatively, the UE transmits UCI in the PUSCH in the second CC in response to the PUCCH overlapping in time with the PUSCH and the first CC being associated with a same carrier group as the second CC. Furthermore, the UE may apply a diversity scheme for UCI transmissions to achieve improved reliability of UCI feedback. The UE may also indicate which carrier includes UCI based on different DMRS configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive physical downlink control channel (PDCCH) configuration information indicating a set of PDCCH candidates for decoding in a PDCCH monitoring occasion and indicating a set of groupings of PDCCH candidates of the set of PDCCH candidates, wherein the set of groupings is associated with a set of prioritizations. The UE may receive, in a first bandwidth and in the PDCCH monitoring occasion associated with the set of PDCCH candidates, downlink control information (DCI) scheduling resources on a second bandwidth, wherein the DCI is decoded from the set of PDCCH candidates in accordance with the set of prioritizations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support multicast communications, which may relate to a multicast service (for example, a multimedia broadcast multicast service (MBMS)). A communications device such as a UE may transition from an inactive or idle state to a connected state to receive multicast services and provide feedback to the network. A wireless network may implement different techniques to trigger the UE to transition from the idle or inactive state into the RRC connected state to receive multicast services. For example, the UE may receive a trigger message that indicates that the one or more multicast services are available for use by the UE, and the UE may determine whether to transition to an RRC connected state to receive the multicast services based on the trigger message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message associated with scheduling uplink transmissions from the UE on a set of component carriers (CCs). The DCI message may indicate that a first uplink channel on a first CC of the set of CCs at least partially overlaps in time with a second uplink channel on a second CC of the set of CCs. The UE may multiplex, based on the first uplink channel at least partially overlapping in time with the second uplink channel, uplink control information (UCI) with an uplink data transmission on the first CC or the second CC. The UE may transmit the UCI and the uplink data transmission multiplexed on the first CC or the second CC based at least in part on the DCI message.

Abstract: Certain aspects of the present disclosure provide techniques for adjusting PDCCH processing or PDCCH DMRS processing, such as to avoid cell-specific reference signal (CRS) of long-term-revolution (LTE). For example, a UE may adjust at least one of physical downlink control channel (PDCCH) processing or PDCCH demodulation reference signal (DMRS) processing of a first radio access technology (RAT), such as LTE, based on whether one or more resource elements (REs) of a PDCCH candidate in a PDCCH monitoring occasion of the first RAT is configured as overlapping with one or more REs of a CRS of a second RAT, such as 5G new radio (NR). The UE then monitors PDCCH candidate in the PDCCH monitoring occasion based on the adjusting.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that transmission of one or more first messages, to a wireless device and via a first radio access technology (RAT), does not meet a transmission quality threshold associated with the one or more first messages, wherein the one or more first messages are time domain multiplexed with one or more second messages that are to be transmitted to the wireless device via a second RAT. The UE may adjust a prioritization of the one or more first messages or the one or more second messages to prioritize the transmission of the one or more first messages over the one or more second messages. Numerous other aspects are described.
