摘要： Certain aspects of the present disclosure provide techniques for identifying measurement occasions (MOs) to monitor and refrain from monitoring for a repetition of a downlink channel. An example method generally includes determining that, within a monitoring occasion (MO) duration associated with decoding a number of physical downlink control channel (PDCCH) repetitions, the UE should refrain from monitoring at least one MO associated with a first control resource set (CORESET), wherein the MO duration comprises multiple MOs in which the UE is to monitor for repeated PDCCH candidates; refraining from monitoring a first subset of MOs in the MO duration, based on the determination; and monitoring a second subset of MOs within the MO duration.

摘要： Certain aspects of the present disclosure provide techniques for channel state information (CSI) for multiple transmission reception point (mTRP) scenarios. The techniques may provide for dynamic interference measurement for mTRP CSI. A method that may be performed by a user equipment (UE) includes receiving a CSI reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs) and a plurality of resources for interference measurement (IMRs). The method includes determining an indicator based on an association between one or more CMRs and one or more IMRs. A codepoint of the indicator is associated with an IMR or a set of IMRs by an order of the IMRs or the set of IMRs in the configuration, and is associated with a CMR, a CMR pair, or a part of the ports of a CMR. The method generally includes performing CSI measurement based on the association.

摘要： In an aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group for a preamble is associated with a downlink receive capability of the UE. In another aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group is associated with a group-specific RA-RNTI that is used to scramble an associated DCI communication. In another aspect, UEs performing a RACH procedure with a BS via different sets of ROs may monitor the same GC-DCI scrambled with a common RA-RNTI. In another aspect, a UE and BS perform a 2-Step RACH procedure whereby a Msg-A payload includes information indicative of a downlink receive capability level associated with the UE.

摘要： Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive an indication of an uplink transmission timing pattern configuration for transmitting uplink transmissions on a first carrier. The UE may identify to use both the first carrier and a second carrier during a single uplink transmission mode, where the UE may transition between sending the uplink transmissions on the first and second carriers. The UE may also determine, based on the uplink transmission timing pattern configuration, a timing of uplink carrier switching periods for retuning between transmissions on the first carrier and on the second carrier. As a result, the UE may transmit, during the single uplink transmission mode, on both the first carrier and the second carrier in accordance with the uplink transmission timing pattern configuration for the first carrier and the uplink carrier switching periods.

摘要： Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving, from a base station, one or more random access channel (RACH) configurations. The RACH configurations may allocate resources for a contention-based RACH procedure for accessing a wireless network. Based on the RACH configurations, the UE may determine a set of random access occasions for an association period. From the set of random access occasions, the UE may map one or more indices of a plurality of synchronization signal blocks to one or more random access occasions. Using the one or more random access occasions, the UE may transmit a random access sequence, including one or more repetitions of the random access sequence to the base station to access the wireless network.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may identify a collision between a data transmission and a demodulation reference signal (DMRS) transmission in a full-duplex time-frequency resource. The BS may transmit, to a wireless communication device, an indication of a time-frequency mapping for a zero-power DMRS (ZP-DMRS) in the full-duplex time-frequency resource. The time-frequency mapping for the ZP-DMRS, and a time-frequency mapping in the full-duplex time-frequency resource for the DMRS transmission, may be a same time-frequency mapping. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.
