摘要： A base station may configure a user equipment (UE) with a subset of reference signal (RS) configurations among a set of RS configurations, and transmit a plurality of RSs based on the subset of RS configurations. The RS may be a demodulation RS (DMRS). The plurality of RSs may be configured to span each of the plurality of resource elements (REs) in the active bandwidth part (BWP). The UE may receive the plurality of RSs based on the subset of RS configurations and perform a spur detection based on the plurality of RSs received based on the subset of RS configurations. Each RS configuration of the set of RS configurations may be associated with at least one of the subset of RS configurations that is associated with the plurality of RSs spanning each of the plurality of REs in the active BWP.

摘要： Aspects described herein relate receiving a signal having a waveform including, within a symbol, resource elements for a physical downlink shared channel (PDSCH) and separate resource elements for multiple pilots to enable phase tracking, estimating, based on the multiple pilots, a channel response of the PDSCH, and removing, from the signal, a phase noise computed based on the channel response estimated for the PDSCH.

摘要： Certain aspects of the present disclosure provide techniques for cyclic shift selection for physical sidelink control channel retransmissions. A method that may be performed by a first user equipment (UE) includes monitoring one or more sidelink control information (SCI) transmissions from one or more second UEs. The method generally includes determining, based on the one or more SCI, whether one or more collisions occur between one or more retransmissions of the one or more SCI transmissions by the one or more second UEs and a scheduled SCI transmission by the first UE. The method generally includes selecting a cyclic shift to use for the scheduled SCI transmission by the first UE based at least on the determination.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting device may reduce a channel overhead of a peak suppression information message (PSIM) by reducing amplitude signaling of clipped peaks of a data signal. To avoid including amplitude information for each clipped peak of a time-domain data signal in a PSIM, the transmitting device may subtract a constant amplitude offset from each peak above a clipping threshold in the time-domain data signal. The transmitting device may indicate the amplitude offset in the PSIM, and a receiving device may reconstruct the data message based on the amplitude offset. In some examples, the transmitting device may indicate a peak to average power ratio (PAPR) in the PSIM, such as a PAPR of a maximum peak in the data signal. Based on the indicated PAPR, the receiving device may perform a calculation to determine the amplitude offset for reconstructing the data message.

摘要： Methods, systems, and devices for notifying puncturing of a physical downlink shared channel (PDSCH) are described. In some examples, a user equipment (UE) may receive, from a base station, a first control message identifying a set of resources used for transmissions by the base station. The UE may receive a second control message that includes an indication of a procedure used by the base station for a collision between the set of resources and a downlink channel transmitted to the first UE by the base station. In some examples, the UE may receive and decode signals on the downlink channel according to the indicated procedure.

摘要： A method of wireless communication includes transmitting, by a wireless communication device, a first Synchronization Signal Block (SSB) transmission during a first slot. The method further includes transmitting, by the wireless communication device, at least a second SSB transmission during the first slot, the second and all other optional SSB transmissions on the first slot carry the same data as the first SSB transmission. The SSB transmissions are transmitted using spatially separated beams. Other aspects and features are also claimed and described.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive pilot signaling associated with inphase and quadrature (IQ) mismatch estimation for a set of antennas of a base station. The UE may measure pilot signals for each of the set of antennas based on a pilot signal pattern of the pilot signaling, and calculate an estimation of an IQ mismatch for each antenna of the set of antennas of the base station based on measuring the pilot signals. The base station may receive, from the UE, a report including an indication of the estimation of the IQ mismatch for each antenna of the set of antennas of the base station based on the pilot signals.

摘要： Methods, systems, and devices for wireless communications are described. A first wireless device may communicate, with a second wireless device, a first set of messages of a first message type that are acknowledged according to an acknowledgement procedure. The first wireless device, the second wireless device, or both may select a first subset of messages of the first plurality of messages and a first subset of bits from each message of the first subset of messages based on the first set of messages being acknowledged and according to a sampling configuration common to both the first wireless device and the second wireless device. The first wireless device, the second wireless device, or both may generate a key using bit values of the first subset of bits from each message of the first subset of messages, encoding a message using the key, and communicate the encoded message.

摘要： A user equipment (UE) may monitor multiple beam pair links (BPLs) including a first BPL currently used by the UE to communicate with a network node (e.g., a base station), and a second BPL. The first BPL comprises a first network beam and a first UE beam, and the second BPL comprises a second network beam and a second UE beam. The UE may decide to switch beams from using the first BPL to using the second BPL based on signaling from the network node or autonomously. When the beam switch is made, the UE switches uplink (UL) transmission from over the first UE beam to over the second UE beam. After the beam switch is made, the UE transmits in the UL over the second UE beam using UL timing adjusted based on the first and second propagation delays.
