摘要： Techniques for beam-based relay node switch. An example method of wireless communication by a first wireless node generally includes relaying wireless communications between a user equipment (UE)(120, 120a-y) and a network entity; transmitting, to one or more second wireless nodes, relay request signals via a plurality of beams(402a-d, 602a-d, 604a-b, 706a-b) at relay request signal occasions(1, 2, 3), wherein each of the relay request signals indicates a request to switch relay services of the UE(120, 120ay) from the first wireless node to the one or more second wireless nodes; and switching the relay services of the UE(120, 120a-y) to at least one of the one or more second wireless nodes.

摘要： Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

摘要： Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.

摘要： Certain aspects of the present disclosure provide techniques for a user equipment (UE) to efficiently provide feedback regarding preferred beams to a base station (BS) that transmits with different beams from different elevations. The techniques generally involve the BS transmitting first reference signals transmitted, using a plurality of elevation beams. The UE selects at least one preferred elevation beam based on the first reference signals and feeds this back to the BS. The BS transmits second reference signals using the preferred elevation beam and a plurality of azimuthal ports. The UE provides a second stage channel feedback to the base station, based on the second reference signals.

摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may support simultaneous transmissions of data on an uplink shared channel that is associated with a first cell, and control information such as uplink control information on an uplink control channel associated with a second cell. The UE may receive scheduling information that indicates a time domain overlap of scheduled transmissions associated with the uplink control channel and the uplink shared channel, and a multiplexing configuration for the UE which indicates whether the UE is to multiplex the uplink control information on the uplink control channel or whether the UE is to multiplex the uplink control information on the uplink shared channel.

摘要： Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform channel state information measurements on reference signal transmissions from a base station. The UE may identify a set of cross layer coefficients associated with a set of spatial layers based on the channel state information measurements. The UE may additionally identify a set of precoding coefficients associated with a spatial layer from the set of spatial layers. In some implementations, the set of precoding coefficients may be based on the set of cross layer coefficients. In some examples, the UE may transmit the set of cross layer coefficients and the set of precoding coefficients to the base station.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may report basis subset selection for a set of beams, where the basis vectors are used for frequency domain compression. To reduce reporting overhead, the UE may transmit two reports indicating the basis vectors. The first report may include first information for the basis vectors and is of a known payload size to both the UE and a base station, while the second report may include second information for the basis vectors and may have a payload size dependent on the first information. The base station may decode the first report and may use the decoded first information to decode the second report. Based on the first and second information, the base station may determine the reported set of basis vectors to use for frequency domain compression and may determine non-zero precoding coefficients.

摘要： Methods, systems, and devices for wireless communications are described for configuring contention-free uplink resources and contention-based uplink resources as preconfigured uplink resources (PUR) available for a user equipment (UE) to transmit one or more uplink transmissions without a specific allocation for the uplink transmission from a base station. Each of two or more UEs may be configured with separate portions of contention-free PUR that each UE may use to transmit a relatively small first uplink communication that provides an indication that the UE will transmit a relatively larger second uplink communication using contention-based PUR. The UE may transmit a buffer status report (B SR) using the contention-free PUR. The first communication may provide an indication of one or more physical layer parameters associated with the second uplink communication. The UE may transmit the second uplink communication using the indicated one or more physical layer parameters via the contention-based uplink resource.
