Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a collision between a first uplink transmission and a second uplink transmission, wherein the first uplink transmission is a high priority uplink transmission and the second uplink transmission is a low priority uplink transmission; and cancel the second uplink transmission during a defined time period, wherein the defined time period has an end point based at least in part on a processing time and an offset, and a start point based at least in part on a triggering event for the first uplink transmission or a UE capability. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more overlaps between a first set of uplink transmissions on one or more master cell groups (MCGs) and a second set of uplink transmissions on one or more secondary cell groups (SCGs), wherein the first set of uplink transmissions are associated with respective first priority levels and the second set of uplink transmissions are associated with respective second priority levels; determine a power sharing configuration for the first set of uplink transmissions and the second set of uplink transmissions; and drop one or more transmissions, of at least one of the first set of uplink transmissions or the second set of uplink transmissions, based at least in part on the respective first priority levels and the respective second priority levels.

Abstract: Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a capability of the UE relating to a carrier configuration of the UE, wherein the carrier configuration relates to carriers of at least two different numerologies; and transmit information identifying the capability, wherein the information identifying the capability identifies a bandwidth or number of carriers that is supported for carriers of a first numerology and one or more scaling values associated with one or more numerologies other than the first numerology. A base station may receive information identifying a capability of a UE relating to a carrier configuration of the UE, wherein the carrier configuration relates to carriers of at least two different numerologies; and determine a configuration for communication with the UE based at least in part on the information identifying the capability. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.

Abstract: The present disclosure provides techniques configuring channel state information (CSI) reporting for certain service types, such as the ultra-reliable low latency communications (URLLC) service type. In some cases, a UE may obtain information regarding a first set of channel state information (CSI) reporting configurations for a first service type separate from a second set of CSI reporting configurations for a second service type, receive a first downlink control information (DCI) scheduling a CSI report for the first service type on at least one physical uplink shared channel (PUSCH), generate at least one CSI report for the first service type based on one of the first set of CSI reporting configurations selected based on a field in the DCI, and transmitting the CSI report for the first service type on the PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type. The UE may select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on a first priority associated with the first service type and a second priority associated with the second service type. Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.
