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： Enhanced channel state information (CSI) procedures for full dimension-multiple input, multiple output (FD-MIMO) is discussed in which a number of CSI reference signal (CSI-RS) ports configured for a user equipment (UE) is determined. In response to the CSI-RS ports including both horizontal and vertical ports, the UE may determine a first precoding matrix from a plurality of precoding matrices constructed by a Kronecker product of a horizontal precoding matrix and a vertical precoding matrix. The UE selects a predetermined number of precoding vectors out of the first precoding matrix and generates a wideband precoding matrix, based on the selected predetermined number of precoding vectors. The UE reports one or more CSI reports, wherein the CSI reports includes at least one precoding matrix indicator (PMI) for the first precoding matrix and at least an indication of the selection of the predetermined number of precoding vectors.

摘要： Enhanced channel state information (CSI) feedback is disclosed for full dimensional multiple input, multiple output (FD-MIMO) operations. In one aspect, a CSI process is defined that may be used to identify 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： 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： 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： Certain aspects of the present disclosure support demodulation reference signal (DMRS) enhancement for higher order multi-user multiple-input multiple-output (MU-MIMO) communications. An example method generally includes determining a plurality of ports of a multi-dimensional array of transmit antennas and a number of spatial multiplexed layers for transmission to a plurality of user equipments (UEs), configuring a demodulation reference signal (DMRS) pattern by multiplexing the layers or the ports in the DMRS pattern, using an orthogonal cover code (OCC) and one or more code division multiplexing (CDM) groups, and transmitting DMRS symbols based on the configured DMRS pattern using the multiplexed layers and the 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.
