Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform uplink reference signal bundling for access link communications and transmit sidelink communications using time or frequency division multiplexed resources. The UE may determine to drop or to transmit a sidelink communication based on a relationship with multiple instances of an uplink reference signal that are to maintain phase continuity. The UE may drop a sidelink communication when a time duration between two instances of the uplink reference signal is less than or equal to a time threshold value, and may transmit the sidelink communication when the time duration exceeds the time threshold value. In frequency division multiplexed cases, the UE may set a transmission power for each instance of the uplink reference signal, and the sidelink communication may use a remaining amount of power.

Abstract: The present disclosure provides techniques for addressing switching times of Integrated Access and Backhaul (IAB) child nodes. For example, a parent IAB node may determine a switching time for the child IAB node to switch from transmitting on a backhaul/uplink to a parent node (with transmit power control) to transmitting on an access/downlink to a user equipment (UE) or other child IAB node. The parent IAB node may then configure the IAB child node according to the determined switching time (e.g., by scheduling the IAB child node accordingly or setting one or more timing advance parameters).

The one or more processors are also configured to generate first monaural audio output at the first audio output device based on the spatial audio data.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure relate to an in-coverage user equipment (UE) relaying broadcast messages to out-of-coverage UEs using one or more messaging techniques over a sidelink channel. The in-coverage UE may monitor for broadcast messages to relay the broadcast messages to out-of-coverage UEs. In some cases, the in-coverage UE may determine to relay broadcast messages to the out-of-coverage UEs based on one or more metrics. Additionally, the in-coverage UE may determine whether the broadcast message is to be included in a groupcast, broadcast, or unicast signaling. Based on the determination to relay broadcast messages, as well as whether the alert message is to be included in a groupcast, broadcast, or unicast signaling, the in-coverage UE may leverage sidelink communications to relay broadcast messages to the out-of-coverage UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may determine a phase noise profile and may transmit the phase noise profile to a receiving device. The receiving device may use the phase noise profile and received phase tracking reference signals to more accurately determine phase errors on a wireless channel between the two devices and compensate for the phase noise errors. In examples where the UE transmits the phase noise profile to the base station, the UE may include the phase noise profile in a measurement report or in a radio resource control (RRC) message, among other examples. In examples where the base station transmits the phase noise profile to a UE, the base station may include the phase noise profile in a broadcast message, a unicast message, or an RRC message.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station and a user equipment (UE) may use multiple transmissions associated with a random access procedure to refine a beam that is used for subsequent portions of the access procedure. A UE may transmit a random access request to the base station and, in response thereto, the base station may transmit a control channel order to the UE. The control channel order may indicate that the UE is to transmit a modified random access request to the base station. The base station may monitor for the modified random access request using different beamforming parameters in order to determine a refined beam to be used for a subsequent transmission in the random access procedure. The base station may then use the refined beam to transmit a random access response to the UE, and complete the access procedure.

Abstract: Dynamic time division duplex (TDD) is a flexible transmission technique allowing different user equipments (UEs) to operate in a downlink mode or an uplink mode depending on the instantaneous traffic load. As a result, a UE transmitting on an uplink channel may interfere with a neighboring UE receiving on a downlink channel. UEs may coordinate communication parameters to reduce cross-link interference. A UE may determine a preferred value(s) for a first communication parameter comprising a beam direction or a slot format index (SFI). The UE receives a candidate value(s) for the first communication parameter, the candidate value(s) being based on communications between a second UE and a first base station. The UE selects a first value among the preferred values based on the received candidate value(s); and initiates communications with a second base station using the first value for the first communication parameter.

Abstract: This disclosure provides methods, devices and systems for data parsing for resource unit (RU) aggregation. A wireless communication device (such as an access point (AP) or a station (STA)) may allocate a set of RUs for a receiving device in a basic service set (BSS). The set of RUs may be associated with multiple bandwidth segments of a bandwidth allocation and may be non-contiguous or contiguous. The wireless communication device may determine a data parsing and encoding scheme for a set of information bits. The data parsing may be implemented at a medium access control (MAC) layer or physical (PHY) layer and the encoding may correspond to a joint encoding or a separate encoding for each RU of the allocation. The wireless communication device may then distribute the coded bits to the set of RUs for transmission.
