Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may enable a first wireless device (e.g., a parent node) to transmit a control message to a second wireless device (e.g., a child node). The control message may include a resource reservation for communication with the second wireless device. The second wireless device may receive the control message and may transmit an acknowledgment message acknowledging successful reception of the resource reservation. The first wireless device may monitor for the acknowledgment message and may communicate with the second wireless device based on whether the acknowledgment message is received. For example, if the first wireless device receives feedback acknowledging successful reception of the resource reservation at the second wireless device, the devices may communicate data in the reserved resources. Otherwise, the first wireless device may retransmit a control message if the first control message was not successfully received.

Abstract: Aspects are provided for generation and transmission of MDMRS which allow matching of nonlinear model impact or properties between DMRS and data in DFT-s-OFDM waveforms as well as CP-OFDM waveforms. A UE transmits, to a network entity, an MDMRS generated from a DMRS. The MDMRS has a PAPR distribution matching a PAPR distribution of a signal including data in an uplink channel. A target PAPR of the MDMRS is based on a modulation scheme of the data. The UE also transmits the data in the uplink channel, where the uplink channel includes a PUCCH or a PUSCH. As a result of the ability of MDMRS to match the nonlinear impact of DMRS and PUSCH or PUCCH, the network entity may compensate for any EVM that may occur as a result of PAPR reduction by a nonlinear operator of the UE, and communication performance may thereby be improved.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

Abstract: This disclosure provides systems, methods, apparatuses, and computer programs encoded on computer storage media, for wireless communication. Various aspects support beam switching and changing antenna array configurations for communicating in a near field range. In some examples, a user equipment (UE) may transmit a beam group indicator to a network entity, and the UE and the network entity may perform beam switching operations associated with switch communication beams in association with changes to a distance between the UE and the network entity. In some such examples, the beam switching may switch from using beam weights for communications in a far field range to beam weights for communications in a near field range. Additionally or alternatively, the network entity may change configurations of an antenna array used to communicate with the UE in association with changes to the distance. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, mapping information indicating, for each bandwidth part (BWP) of multiple BWPs, a mapping between a respective beam direction of multiple beam directions and the BWP. The method further includes receiving an allocation of a first BWP. The method also includes communicating, via the first BWP, one or more first messages using a first beam having a first beam direction, and receiving, from the base station, a change indicator associated with a second BWP or a second beam direction. The method includes communicating, via the second BWP, one or more second messages using a second beam having a second beam direction. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit at least a first synchronization signal block (SSB) over a first sub-band in a first spatial direction and a second SSB over a second sub-band in a second spatial direction, wherein the at least the first SSB and the second SSB are transmitted at a same time and wherein the at least the first SSB and the second SSB comprise a set of SSBs, the at least first sub-band and the second sub-band comprise a first set of sub-bands, and the at least first spatial direction and the second spatial direction comprise a first set of spatial directions. Numerous other aspects are described.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.
