摘要： This disclosure provides systems, methods and apparatuses for physical uplink control channel (PUCCH) transmission for time division multiplexed uplink carriers. In one aspect, a missed PUCCH transmission occasion may be rescheduled in a next valid uplink slot, thus reducing a delay in transmitting uplink control information. In some aspects, a PUCCH transmission occasion scheduled during an invalid uplink slot on one uplink carrier can be included in a physical uplink shared channel (PUSCH) transmission on another uplink carrier having a valid uplink slot in the slot when the PUCCH transmission occasion is scheduled, thus further reducing delays in transmitting the uplink control information. In some aspects, multiple uplink carriers can have a PUCCH configuration, which allows the UE to dynamically select the uplink carrier for the PUCCH transmission (such as based on which uplink carrier has a valid uplink slot in the slot when the PUCCH is to be transmitted).

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described that support non-periodic channel state information (CSI) triggering and reporting in wireless communications. In cases where two or more CSI report requests trigger multiple CSI report transmissions in an same uplink slot, a user equipment (UE) may format at least a subset of the multiple CSI reports according to a formatting configuration for transmission of multiple CSI reports in a same uplink slot. The UE may use allocated resources in the uplink slot for each CSI report that are allocated by the base station in the corresponding CSI report request. In some cases, the UE may combine the multiple CSI reports, or parts thereof, into a combined CSI report that may be transmitted using allocated resources of one of the CSI report requests.

摘要： Wireless communication that includes transmission, reception, and configuration of a CSIRS with a configurable bandwidth is discussed. A base station/gNB may determine a number of antenna ports to be used for wireless communication. The base station/gNB may allocate a first plurality of frequency resources for the transmission of the CSIRS based on the determined number of antenna ports, and may transmit the CSIRS over the first plurality of frequency resources. A mobile device may receive the CSIRS over the first plurality of frequency resources and estimate at least one of channel quality and interference associated with the first plurality of frequency resources based on the received CSIRS.

摘要： Enhanced channel state information (CSI) feedback is disclosed for full dimensional multiple input, multiple output (FD-MIMO) operations. In one aspect, a single CSI process is defined that is configured with an azimuth and elevation CSI-reference signal (RS) ports. A user equipment (UE) will send a precoding matrix indictor (PMI) report including a precoding matrix indicator (PMI) for the azimuth ports and a PMI for the elevation ports. One of the PMIs is assigned a low rank. The base station will use the two PMIs to create a whole channel precoding matrix. In another aspect, a single CSI process is configured having a plurality of CSI-RS resources. The UE generates channel measurement information for each of the CSI-RS resources, but only sets a CSI report to the base station of a subset of the total number of resources.

摘要： Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information message scheduling a downlink transmission that comprises a zero-power reference signal for the UE to use for rate matching during the downlink transmission. The UE may receive a signal triggering transmission of an aperiodic reference signal during the downlink transmission. The UE may determine whether the UE supports search space sharing. The UE may perform, upon determining that the UE supports search space sharing, rate matching around the aperiodic reference signal.

摘要： 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.
