Abstract: Methods, systems, and devices for wireless communications are described. To save energy at the network, synchronization signal blocks (SSBs) may be transmitted in an on-demand manner. For example, the network may transmit an SSB in response to a request for an SSB or an uplink wake-up signal (WUS) from a user equipment (UE). SSBs may be mapped to corresponding random access channel occasions (ROs) via control signaling such as radio resource control or system information. For example, the described techniques provide for rules and/or signaling that may indicate whether a network entity should monitor for, and thus whether a UE may transmit, in ROs corresponding to on-demand SSBs. In some examples, a UE may transmit a request for an on-demand SSB, receive an SSB based on the request, and selectively transmit a message to the network entity in an RO corresponding to the SSB based on reception of the SSB.

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: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to beamforming configurations of synchronization signal blocks to reduce power consumption at a user equipment (UE) and a network entity. The UE monitors for a first set of beamformed synchronization signals including a first subset of synchronization information. The UE transmits one or more beamformed wake-up signals (WUSs) based on the monitoring for the first set of beamformed synchronization signals. The UE monitors, in response to transmitting the one or more beamformed wake-up signals, for a second set of beamformed synchronization signals including a second subset of the synchronization information. Each beamformed synchronization signal of the first set of beamformed synchronization signals corresponds to multiple beamformed synchronization signals of the second set of beamformed synchronization signals.

Abstract: Disclosed is a method for wireless communication for determining the position of a wireless node. The method comprises receiving a set of reference signals from a set of at least four positioning devices, wherein the positioning devices are not arranged in a single plane. A signal propagation delay of each one of the set of reference signals is determined and a position of each one of the set of positioning devices is obtained. A convex localization problem is solved for the wireless node based at least in part on the determined signal propagation delay of each one of the set of reference signals and the position of each one of the set of positioning devices. The position of the wireless node is determined based at least in part on solving of the convex localization problem.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network-controlled repeater (NCR) node may obtain measurements related to backhaul links between the NCR node and network nodes that forward radio frequency (RF) signals through the NCR node and to an access link between the NCR node and a user equipment (UE). The end-to-end link quality between the UE and each network node may be estimated (for example, by the NCR node or a current serving cell) in accordance with the measurements and a gain and/or transmit power used to forward RF signals, and the current serving cell may use the estimated end-to-end link quality to arrive at handover decisions for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the techniques described herein may support balancing of system usage costs with performance. For example, a user equipment (UE) may transmit a usage cost message indicating usage costs associated with each unique set of operating parameters supported by the UE, including a first set of operating parameters associated with a first usage cost and a second set of operating parameters associated with a second usage cost. Each set of operating parameters may further be associated with a respective quantity of receive beams of the UE for operating according to the respective set of operating parameters. Additionally, the UE may receive an indication for the UE to operate according to the first set of operating parameters or the second set of operating parameters based on the first usage cost and the second usage cost.

Abstract: A method for wireless communication by a UE includes receiving, from a network node, a first message indicating at least a first discontinuous reception (DRX) configuration associated with a DRX cycle at the network node. The DRX cycle may be enabled or disabled in accordance with whether the first DRX configuration is in an activated state. The method also includes receiving, from the network node, a second message indicating a group of uplink (UL) transmission configurations including at least a first UL configuration associated with the activated state of the first DRX configuration and a second UL configuration associated with the deactivated state of the first DRX configuration. The method further includes transmitting, to the network node, a third message in accordance with the first UL configuration in accordance with first DRX configuration being activated or the second UL configuration in accordance with first DRX configuration being deactivated.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless devices that relay directional wireless signals). For example, aspects of the present disclosure may help enable repeaters to provide greater assistance in an access procedure, for example, by generating and sending SSBs without (or with limited) gNB involvement and monitoring for RACH-related transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may determine a set of restricted IAB-DU beams that are not to be used by the IAB-DU while a mobile termination function of the IAB node is using one or more IAB-MT beams. The determination is based on measurements related to interference caused by simultaneous operations of the IAB-DU and IAB-MT in multiplexing modes. The IAB node transmits signaling that indicates the restricted IAB-DU beams and associates the set with the IAB-MT beams. Additionally or alternatively, an IAB node can receive such signaling from a parent node, perform operations using the IAB-MT beams, and simultaneously perform operations using certain IAB-DU beams not included in the set of restricted beams. Numerous other aspects are provided.
