Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a cancellation indication, to drop one or more scheduled uplink communications associated with a first one or more scheduled uplink resources, in a group-common downlink control information message of a downlink control channel communication; identify, based at least in part on the cancellation indication, a second one or more scheduled uplink resources for a particular uplink communication; and transmit the particular uplink communication using the second one or more scheduled uplink resources. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure propose methods for improving phase continuity in an uplink transmit time interval (TTI) bundle. A first method may include identifying a segment of UL subframes in the TTI bundle and maintaining substantially the same transmit power/timing/frequency when transmitting data to a node over the segment of UL subframes in the TTI bundle. Another method may include ignoring reception of downlink subframes for a duration of the TTI bundle.

Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: Aspects described herein relate to encoding uplink communications based on a coding table including determining to avoid certain portions of a coding table that may result decoding errors, or using a modified coding table, to improve decoding results. In one aspect, a network can transmit, to a device, a configuration indicating whether to use a modified coding table for encoding uplink communications.

Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration for a multiple transmission reception point (TRP) transmission, such as a non-coherent joint transmission (NCJT). A method by a base station (BS) includes providing a user equipment (UE) with a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource comprising a set of ports or port groups. The BS signals the UE to enable the UE to send a CSI report including CSI for more than one CSI-RS resource or for a CSI-RS resource comprising more than one port group and receives a CSI report from the UE.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for performing rate matching for a physical downlink shared channel (PDSCH). An example method generally includes monitoring for at least first and second downlink control information (DCI) formats for scheduling a physical downlink shared channel (PDSCH), determining a bitwidth of a rate matching indicator field of at least one of the first DCI format or the second DCI format, and performing PDSCH rate matching for a PDSCH scheduled by a DCI of the first or second DCI format based, at least in part, on the rate matching indicator field in the DCI or a format of the DCI.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: A configuration to enable a base station to schedule cross carrier scheduling of uplink and/or downlink transmissions using a DCI. The apparatus transmits, to a UE, a PDCCH including a cross carrier schedule. The PDCCH comprises DCI configured to schedule an uplink transmission or a downlink transmission. The DCI includes at least one FDRA field indicating RBs for the uplink transmission or the downlink transmission. The apparatus communicates with the UE based on the cross carrier schedule configured by the DCI.

Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration with a codebook list, for example, for non-coherent joint transmission (NCJT). A method for wireless communication that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource includes a set of ports or port groups. The UE receives a list of codebooks associated with the configuration. The UE determines at least one codebook, from the list of codebooks, to apply for one or more triggered CSI-RS resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may apply a timing adjustment for a sidelink connection with a second UE, wherein the timing adjustment causes a slot structure on the sidelink connection to align with a slot structure on an uplink connection with a base station; and transmit sidelink feedback, received via the sidelink connection, on the uplink connection based at least in part on the timing adjustment, wherein the sidelink feedback is mapped to a slot on the uplink connection, of two or more slots on the uplink connection that the sidelink feedback overlaps, based at least in part on a rule. Numerous other aspects are provided.
