摘要： A user equipment (UE) may transmit, to a base station, at least one of a physical layer (L1) report of the current beam. The base station may receive the at least one of the L1 report of the current beam from the UE, and transmit at least one physical downlink control channel (PDCCH) repetition based on a first repetition option associated with the L1 report received from the UE. The UE may receive, from the base station, the PDCCH repetition based on the first repetition option associated with the L1 report received from the UE. The base station and the UE may communicate physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) scheduled by the at least one PDCCH repetition based on the first repetition option associated with the L1 report or the CSI feedback.

摘要： Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

摘要： Certain aspects of the present disclosure provide techniques for random access channel (RACH) configuration. Certain aspects are directed to a method for wireless communication by a user equipment (UE). The method generally includes: receiving, from a base station, a message comprising random access channel (RACH) configurations including a first RACH configuration indicating a first set of resources for reduced capability UEs supporting at least one first capability, a second RACH configuration indicating a second set of resources for coverage enhanced UEs supporting at least one second capability, and a third RACH configuration indicating a third set of resources for UEs supporting the at least one first capability and the at least one second capability; and transmitting a RACH message based on at least one of the RACH configurations.

摘要： Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include transmitting, to a base station, a channel state information (CSI) report associated with a beam switch. The example method may further include performing the beam switch based on the CSI report and an absence, for a period of time after transmission of the CSI report, of a downlink control information (DCI) including a transmission configuration indicator (TCI) indication.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure event associated with the UE. The UE may detect a first condition of the UE. The UE may perform one or more actions associated with beam failure recovery based at least in part on a measure of similarity between the first condition of the UE and a second condition of the UE associated with a past beam failure event. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a request for physical uplink shared channel (PUSCH) repetition associated with a radio resource control (RRC) connection request message of a random access channel (RACH) procedure. The UE may transmit at least one PUSCH repetition associated with the RRC connection request message based at least in part on the request. Numerous other aspects are described.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PUCCH/PUSCH DMRS bundling. A UE may transmit, to a network entity, a first indication of a maximum DMRS bundling duration for maintaining transmit phase coherence for transmitted DMRS. The UE may receive, from the network entity based on the first indication of the maximum DMRS bundling duration, a second indication of at least one of a DMRS bundling activation or a DMRS bundling duration. Based on the at least one of the DMRS bundling activation or the DMRS bundling duration, the UE may transmit at least one UE repetition including bundled DMRS.

摘要： Aspects of the present disclosure relate to techniques for physical uplink control channel configuration and coverage enhancement in a wireless communication network. A base station can dynamically indicate a repetition factor for an uplink control channel to improve coverage of the uplink control channel. The base station can explicitly or implicitly indicate the repetition factor using various signaling techniques. The interpretation of an indication of a repetition factor can depend on one or more parameters, for example, a physical uplink control channel (PUCCH) format, an uplink control information size, a code rate, and/or a PUCCH resource set used for the PUCCH.

摘要： Disclosed are techniques for determining tone patterns and associated overlay codes for transmission of reference signals. A tone pattern (e.g., with each tone pattern occupying a resource element in a resource block) can be determined for a reference signal for use in wireless communications between a receiving device and a transmitting device. The tone pattern can include an irregular combination of resource elements in one or more resource blocks for the reference signal. The resource elements can be shared by a plurality of antennas for communication of one or more reference signals between at least the user equipment and the base station. An overlay code may be determined for the tone pattern. Information associated with the transmission of the reference signal using the tone pattern and the overlay code may be communicated by the receiving device.

摘要： Disclosed are techniques for determining tone patterns for transmission of reference signals. One or more parameters associated with communications with a base station over a time duration, may be determined by a user equipment. The user equipment may determine, based on the one or more parameters, a tone pattern for a reference signal for use in communications with the base station over a future time duration. The user equipment may then transmit the tone pattern to the base station. The user equipment may then receive the reference signal from the base station, over the tone patterns.
