Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adjusting communication timings of beams (e.g., of beam pair links) within a beam timing advance group (TAG). In some cases, a base station may determine that transmission timing at a UE may be misaligned between multiple beams. The base station may configure a set of beams into a beam TAG, and may send a timing advance (TA) command for the beam TAG. A common timing reference value may be identified based on the TA command. UEs performing uplink transmissions may determine a TA value for the beam TAG based on the common timing reference value, and may adjust a communication timing for one or more of the beams within the beam TAG based at least in part on the common timing reference value and the timing advance value.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a scheduling request message to the base station using at least one of a resource or a waveform selected based at least in part on the selected DL beam.

Abstract: Methods, systems, and devices for wireless communications are described. a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may determine, when in communication with a plurality of other wireless nodes via a plurality of links of a network, a plurality of transmit powers for the plurality of links, wherein the plurality of transmit powers are selected to control inter-link interference or to satisfy a maximum transmit power criterion. The wireless node may transmit, using the plurality of transmit powers for the plurality of links, information, to the plurality of other wireless nodes, concurrently, based at least in part on determining the plurality of transmit powers for the plurality of links. Numerous other aspects are provided.

Abstract: Techniques are provided for power control in directional beam environments. A user equipment (UE) may determine one or more power parameters on a beam-by-beam basis. Each directional uplink transmission beam in a communication link between the UE and the base station may be independently controlled using these beam-specific power parameters. Examples of these beam-specific power parameters may include a maximum output power for a given directional uplink transmission beam and a difference between the maximum output power for the given directional uplink transmission beam and an estimated transmit power for the given directional uplink transmission beam. The UE may report one or more of these beam-specific power parameters to a base station using a beam-specific report.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines that a first external timing source timing signal is available at a first UE. The apparatus also synchronizes the first UE using the first external timing source based timing signal when the first external timing source timing signal is available. Additionally, the apparatus transmits a synchronization signal indicating that the first UE is synchronized using an external timing source timing signal.

Abstract: Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a first radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the transmitted signal at the first radio frequency via one or more scan angles or beamforming directions. Repeaters may perform heterodyning or downconverting on the received signal to reduce a frequency of the signal from the first frequency to an intermediate frequency (IF), and then band-pass filter the IF signal around a desired center frequency. The repeater may then heterodyne or upconvert the filtered IF signal back to the first frequency for the retransmission of the signal.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host device may determine a pool of preconfigured resources for discovery. The preconfigured resources are designated for one or more of: a discovery preamble, a query signal, a discovery message, and a random access preamble. The host device may transmit the discovery preamble on one or more resources designated for the discovery preamble. A client device may receive the discovery preamble and determine that the client device is interested in receiving information regarding the host device. The client device may transmit a query signal if interested. The host device may determine whether the query signal is received on a resource designated for the query signal in response to the discovery preamble. The host device may transmit a discovery message in response to receiving the query signal.

Abstract: Certain aspects of the present disclosure provide techniques for avoiding conflicts of resources assigned to one or more signals with resources assigned to Random Access Channel (RACH) in an Integrated Access and Backhaul (IAB) network. Configurations for first and second sets of signals are obtained for a first and second base station (BS) respectively. Based on the obtained configurations, a RACH configuration is determined for the first BS for performing a RACH procedure with the second BS over a wireless backhaul link, wherein one or more Physical RACH (PRACH) occasions according to the determined RACH configuration do not conflict with resources used for at least one of the first or the second set of signals. The determined RACH configuration is communicated to the second BS, wherein the second BS transmits a RACH signal to the first BS based on the determined RACH configuration.
