Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish, with a network entity, a wireless connection that uses a set of symbols per transmission time interval (TTI) for orthogonal frequency division multiplexing (OFDM) communications, where each symbol of the set of symbols may correspond to a fast Fourier transform (FFT) window and may include a guard interval (GI) portion and a data portion within the FFT window. In some examples, the UE may receive a control message indicating at least one parameter associated with a power offset between a data signal of the set of symbols and a reference signal of the set of symbols that is associated with the data signal. As such, the UE may communicate with the network entity, the data signal, and the reference signal according to the indicated power offset using the set of symbols.

A user equipment (UE) may identify a configuration for a set of bandwidth part groups including an intra-group switching delay and an inter-group switching delay, where the intra-group switching delay is smaller than the inter-group switching delay. The UE may communicate with a base station on a first bandwidth part of a first bandwidth part group of the set of bandwidth part groups. The UE may switch to a second bandwidth part of the first bandwidth part group based at least in part on the intra-group switching delay, or the UE may switch to a third bandwidth part of a second bandwidth part group based at least in part on the inter-group switching delay.

Abstract: Methods, systems, and devices for wireless communications provide techniques for multiplexing, in a frequency domain, a synchronization signal block (SSB) and a control resource set (CORESET) to form a multiplexed block that is transmitted using a set of symbols. A base station may transmit multiple multiplexed blocks using multiple different beams with a switching gap provided between each multiplexed block that allows for switching of radio frequency (RF) components between different beams. The switching gap is longer than a duration of a cyclic prefix (CP) that is associated with each symbol of the set of symbols of each multiplexed block. Within one or more of the multiplexed blocks, an associated SSB may use a different waveform than the CORESET. The multiplexed blocks may use a common reference signal for both the SSB and CORESET.

Abstract: Aspects relate to configuration of a combined reference signal configuration including two or more reference signal configurations. Each reference signal configuration may be associated with one or more beam identifiers (IDs) is a respective communication direction. In some examples, the communication direction may be a downlink communication direction, an uplink communication direction, or a sidelink communication direction. Based on the combined reference signal configuration, reference signals associated with the two or more reference signal configurations may be communicated between devices (e.g., between a user equipment (UE) and a network entity or between two UEs). In addition, a UE may transmit a measurement report based on one or more report settings configured for the combined reference signal configuration.

Abstract: Aspects of the disclosure relate to a device initiating an update of active transmission configuration indicator (TCI) states and/or spatial relation configurations. The device measures one or more signal strengths of one or more network entity transmit beams and activates one or more TCI states/spatial relation configurations corresponding to the one or more network entity transmit beams based on the measured one or more signal strengths. The device further outputs a report indicating the one or more activated TCI states or the one or more activated spatial relation configurations. Thereafter, the device obtains, from a network entity, information indicating a network entity transmit beam corresponding to an activated TCI state or an activated spatial relation configuration and switches, based on the information, to at least one device receive beam that is associated with the indicated network entity transmit beam to communicate signals with the network entity.

Abstract: Methods, systems, and devices for wireless communications are described that support blind decoding limit adjustment techniques. A base station may configure a user equipment (UE) with one or more conditions that may trigger an adjustment to a number of blind decoding candidates that are to be monitored at the UE for a control information communication from the base station. A nominal number of blind decoding candidates may be configured at the UE, and the adjustment to the number of blind decoding candidates may reduce the number of blind decoding candidates from the nominal number, thus allowing the UE to perform blind decoding using less processing power, less time, or both. The trigger conditions may include one or more configured conditions that may support reliable communications with fewer blind decoding candidates.

Abstract: A RAN node can indicate to a UE that a compact measurement report is to be used for beam measurements in a measurement report. A compact measurement report uses beam index numbers to indicate a position in a reference set. The reference set has a listing of resource indicators for beam measurements. As such, a reported beam measurement associated with a beam index number is also associated with the resource indicator positioned in the reference set indicated by the beam index number. The beam index numbers can be transmitted using fewer bits than are used for a resource indicator. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the measurement report is transmitted as a compact measurement report.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a configuration of a common PUCCH resource set that is based on a frequency hopping pattern and includes a first set of resource blocks (RBs) of a bandwidth part (BWP) in a first group of symbols and a second set of RBs of the BWP in a second group of symbols. In some designs, the second set of RBs is offset in frequency from the first set of RBs by a fixed hopping distance. In other designs, the BWP is further associated with a second PUCCH resource set that includes a third set of RBs of the BWP that overlaps in part with the first set of RBs of the BWP in the first group of symbols, a fourth set of RBs of the BWP that overlaps in part with the second set of RBs of the BWP in the second group of symbols, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described to support guard interval (GI) configurations for multiple links. For example, a user equipment (UE) may determine a first GI duration for a first transmission reception point (TRP) and a second GI duration for a second TRP, when the UE is operating in a multi-TRP mode. The UE may determine the GI durations based on a difference in timing between signal reception from the first and second TRPs and may transmit a signal to one or both of the TRPs to indicate the GI durations. Based on the indicated GI durations, the first and second TRPs may transmit signaling to the UE that includes or implements the corresponding GI duration for each TRP. For example, the signaling may include a GI appended at the end of each symbol period that has a GI duration corresponding to the respective TRP.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.
