Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Constraints on a source reference signal for quasi-collocation timing reference of a positioning reference signal

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from a network entity, a configuration of one or more positioning reference signal (PRS) resources to measure during a positioning session, the one or more PRS resources having a PRS periodicity Tand a PRS occasion length L, and measures the one or more PRS resources during a measurement period, wherein the measurement period is based on a number of measurement instances of the one or more PRS resources the UE is expected to process multiplied by a periodicity parameter, wherein the periodicity parameter is based on a PRS processing window of 'T' milliseconds, the PRS periodicity T, and a measurement gap periodicity of at least one measurement gap.

Reporting granularity and measurement period for positioning reference signal (PRS) measurements

Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration, the PRS configuration including at least a PRS periodicity defining repetitions of one or more PRS resources associated with at least a first transmission-reception point (TRP), receives a measurement gap configuration including at least a measurement gap repetition period (MGRP) defining repetitions of a measurement gap, and performs one or more positioning measurements of at least the one or more PRS resources during one or more repetitions of a measurement period, the one or more repetitions of the measurement period having an effective measurement periodicity, the effective measurement periodicity based on an alignment periodicity and a time period T during which the UE can process a duration N of PRS symbols, the alignment periodicity based on the PRS periodicity and the MGRP.

Measurement period formulation for reference signal time difference (RSTD) measurements

Embodiments include methods of testing wireless devices for beam forming performance. Various aspects may include determining measurements of communication performance of the wireless device at each of a number of different angular orientations of the wireless device with respect to an antenna within a test chamber, and determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to pass/fail criteria. Further embodiments may include a wireless device testing apparatus configured to perform testing wireless devices for beam forming performance. In some embodiments, a wireless device testing apparatus may include a test chamber, an antenna within the test chamber, a rotatable positioning system within the test chamber configured to hold a wireless device and rotate the wireless device within a range of orientations with respect to the antenna, and a computing device coupled to the antenna and the rotatable positioning system.

Handling of listen before talk (LBT) failures during radio resource control (RRC) procedures is disclosed. A user equipment (UE) may be configured to monitor for consistent uplink and downlink LBT failures on a bandwidth part (BWP) configured for a target cell. When the UE determines that consistent LBT failures are occurring with respect to the BWP, the UE may determine an LBT failure state on the BWP. In response, the UE may execute a recovery procedure, which may include selecting a new BWP associated with the target cell and having configured uplink resources, performing a cell reselection procedure, or switching to idle in order to perform cell selection. The UE may then report the LBT failures according to cell identification and BWP.

Handling of listen before talk failures during radio resource control procedures

Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

Reference timing for multiple transmission and reception points in multi-radio dual connectivity

A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Tone-level interleaving and de-interleaving for broadcast or multicast communications

In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, by a user equipment (UE), an evaluation time period based on a number of a plurality of reference signals that are quasi-co-located (QCL) within one or more measurement windows; measuring, by the UE, a signal quality value of one or more of reference signals within the evaluation time period; and determining, by the UE, whether the signal quality value of one or more of reference signals within the evaluation time period crosses an evaluation threshold.

Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.
