A method and an apparatus for determining an operation mode, a device, and a storage medium are provided. The method includes: determining first information, where the first information is at least one of position information and positioning error information of a target terminal; and determining at least one first operation mode based on the first information, where the first operation mode is associated with at least one of the following: a first beam direction of a reflected signal or a refracted signal of a first device; a beamforming mode of a reflected signal or a refracted signal of a first device; and a polarization mode of a reflected signal or a refracted signal of a first device.

Disclosed is a method including determining, per transmit and receive beam pair of a plurality of beam pairs, a transmit power value based at least partly on a saturation power value of one or more analog-to-digital converters at a receiver; and transmitting, via a transmitter, a signal using the determined transmit power value and a corresponding transmit beam per transmit and receive beam pair of the plurality of beam pairs.

An electronic device may include wireless circuitry with a phased antenna array that conveys radio-frequency signals using signal beams of first and second orthogonal polarizations. The array may sweep over a set of signal beam pairs, each including a respective combination of signal beams of the first and second polarizations. The wireless circuitry may gather performance metric values for each of the polarizations and signal beam pairs. The circuitry may generate a filtered set of signal beam pairs by removing signal beam pairs having performance metric values that differ from a maximum of the wireless performance metric values by more than a threshold. The circuitry may select a signal beam pair from the filtered set having a minimum polarization imbalance. The array may concurrently convey first and second wireless data streams using the selected signal beam pair. Minimizing polarization imbalance may maximize overall data throughput for the device.

Disclosed are systems and techniques for wireless communications. In one example, an apparatus for wireless communication at a first user equipment (UE) can send a first sidelink communication to a second UE using a first beam pair of a unicast link with the second UE, wherein the first beam pair includes a first transmission beam and a first reception beam. In some aspects, the apparatus can determine a fault associated with at least one of the first transmission beam and the first reception beam.

The present disclosure relates to a wireless communication system, and specifically to a method and device therefor, the method comprising the steps of: receiving CSI-RS resource configuration information; receiving DCI indicating CSI-RS transmission; and receiving CSI-RS in one or more CSI-RS resource sets corresponding to the DCI, wherein the DCI corresponds to a CSI-RS resource set in at most one slot on the basis that subcarrier spacing (SCS) within a first range is applied to the CSI-RS transmission, the DCI corresponds to a plurality of CSI-RS resource sets in different slots on the basis that SCS within a second range is applied to the CSI-RS transmission, the first range does not overlap the second range, and the second range is wider than the first range.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a second network node, codebook information that indicates a plurality of beams associated with an oversampled transmitter network node beamforming codebook. The first network node may transmit a beam selection report that indicates at least one suggested transmission beam associated with the oversampled transmitter network node beamforming codebook, wherein the beam selection report is based at least in part on a channel estimate that is obtained without obtaining beam measurements associated with beams that are associated with the oversampled transmitter network node beamforming codebook. Numerous other aspects are described.

A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface (RIS). The AP may perform a control RAT discovery with the RIS and then a data transfer RAT discovery, during which the AP uses the control RAT to control the RIS to sweep over different RIS beams. The AP may transmit radar waveforms while concurrently sweeping over different AP beams. The AP may gather performance metric values from the radar waveforms after reflection off the RIS during the sweep. The AP may identify an optimal RIS beam that produced the best performance metric values. The AP may use the optimal RIS beam to identify the orientation of the RIS, which the AP may use to select AP and/or RIS beams for conveying wireless data between the AP and the UE via the RIS.

Systems, methods, apparatuses, and computer program products for enabling beam diversity for physical uplink shared channel (PUSCH) repetition under multi-transmission points (TRP). A method may include receiving, from a network, a configuration with at least one time offset to account for at least one delay on switching from one transmit beam to another transmit beam, wherein the configuration defines at least one rule applicable to the at least one time offset. The method may also include determining a need for the at least one time offset between consecutive repetitions based on the configuration and the use of transmit beams for the consecutive repetitions. The method may further include applying, based on the determination, the at least one time offset between the consecutive repetitions. Further, a time domain allocation of at least one repetition of the consecutive repetitions may be changed to accommodate the at least one time offset.

The present application is at least directed to an apparatus including a non-transitory memory with stored instructions for beam link pairing the apparatus to a gNB in a new radio. A processor of the apparatus, operably coupled to the non-transitory memory, executes an instruction of detecting synchronization signal blocks (SS). Another executed instruction includes receiving PRACH resource information in a master information block on a PBCH or system information block (SIB) on the secondary PBCH. Another executed instruction includes transmitting PRACH preambles through a set of uplink transmission beams in a subframe including the group of SS blocks. The PRACH preambles may be obtained from the PRACH resource information. Even another executed instruction including determining the apparatus is in a radio resource control (RRC) connected state. A further executed instruction includes measuring, while in the RRC connected state, a multiple set of channel state information reference signals (CSI-RSs) configured by the gNB. Yet a further executed instruction includes transmitting, to the gNB, a single report based on the multiple set of CSI-RSs.

A method for operating a user equipment (UE) comprises receiving configuration information about a transmission configuration indicator (TCI) state indication via a downlink control information (DCI), the configuration information including a set of TCI states and information for configuring the DCI from one of a downlink (DL) DCI (DL-DCI) and a DL-TCI-DCI, wherein the DL-DCI schedules a DL physical DL shared channel (PDSCH) assignment and the DL-TCI-DCI is a dedicated DCI for TCI state indication; receiving, based on the configuration information, the configured DCI; decoding the configured DCI to obtain a TCI state update; determining a receive beam based on the TCI state update; and applying the receive beam for a reception of a DL control or a DL data.
