摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

摘要： Techniques are described for wireless communications at a user equipment (UE). One method includes determining a first cell identifier (ID) associated with a first downlink transmission in a first radio frequency spectrum band of paired radio frequency spectrum bands, determining a second cell ID associated with a second downlink transmission in a second radio frequency spectrum band of the paired radio frequency spectrum bands, and communicating based on the first cell ID and the second cell ID. In some cases, the method may include determining a cell ID associated with a downlink transmission in an uplink radio frequency spectrum band, and receiving the downlink transmission in a subframe of the uplink radio frequency spectrum band. The downlink transmission may be based on the cell ID and a format of a physical uplink shared channel (PUSCH), and may include an eight layer single-user multiple-input multiple-output (SU-MIMO) transmission.

摘要： Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.

摘要： Certain aspects of the present disclosure provide techniques for signaling quasi-coloration (QCL) information for demodulation reference signals (DM-RS) associated with multiple transmission-reception points (multi-TRP). An example method generally includes generating quasi-colocation (QCL) information indicating a first QCL assumption for a first group of demodulation reference signal (DM-RS) ports and a second QCL assumption for a second group of DM-RS ports; and transmitting the QCL information to at least one user equipment (UE) for use in processing one or more transmission associated with at least one of the first group of DM-RS ports and the second group of DM-RS ports.

摘要： Aspects of the present disclosure relate to techniques for non-codebook based UL transmission. In some cases, a UE may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

摘要： Processing relaxation for aperiodic channel state information (CSI) reference signal (CSI-RS) is discussed for networks that include full dimension multiple input, multiple output (FD-MIMO) operations. A user equipment (UE) operating in such a system monitors for the presence of aperiodic CSI-RS. When such aperiodic CSI-RS are detected, the UE may provide process relaxation in CSI reporting by transmitting aperiodic CSI reporting according to an uplink shared channel limitation, or by relaxing the processing of the aperiodic CSI reporting transmitted by the UE, or a combination of both.

摘要： Wireless communications systems and methods related to joint-carrier scheduling using a single downlink control information (DCI) signal. The user equipment (UE) receives from a base station (BS) of a first serving cell, a downlink control information (DCI) that indicates a joint-carrier scheduling scheme. Using the joint-carrier scheduling scheme in the DCI, the UE schedules first data for communication on a first shared channel associated with the first serving cell and second data for communication on a second shared channel associated with a second serving cell.
