Abstract: Aspects described herein relate to establishing a control connection with at least a first node and a second node for receiving control information for providing a repeater function between two or more wireless nodes. Control information can be communicated over the control connection from one or more of at least the first node or the second node. The repeater can provide, based on the control information, the repeater function between the two or more wireless nodes. Other aspects relate to establishing a control connection with a first node for receiving control information for providing a repeater function for one or more upstream nodes, receiving control information over the control connection, determining a conflict in receiving the control information or a conflict within the control information for two or more upstream nodes, and providing, based on the control information and conflict, the repeater function for the one or more upstream nodes.

Abstract: Methods, systems, and devices for wireless communication are described. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) about synchronization signal (SS) beams using the same (e.g., or a similar) framework that is used for channel state information reference signal (CSI-RS) reporting. Because SSs are intended to be broadcast across a wide coverage area in a beamformed manner, the SSs represent a promising complement to existing beam management techniques. Accordingly, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SSs through a channel feedback framework.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam training with relay link are disclosed herein. An example method for wireless communication at a control node includes determining a first set of measurements associated with at least one set of beam pairs. In some examples, the at least one set of beam pairs is associated with a wireless backhaul link between a first wireless device and a relay device, a first relay access link portion between the first wireless device and the relay device, or a second relay access link portion between the relay device and at least one second wireless device. The example method also includes configuring at least one subset of beam pairs of the at least one set of beam pairs based on the first set of measurements. Additionally, the example method includes transmitting information indicating the at least one subset of beam pairs to the relay device.

Abstract: The apparatus may be a first device at a first RU (e.g., UE, base station, etc.). The first RU may be configured to receive, from a control unit, a configuration for relaying or repeating data received from a second RU to a receiving unit. The first RU may further be configured to determine whether first feedback associated with the data is received from the second RU. The first RU may also be configured to transmit second feedback to the receiving unit or the control unit, the second feedback including first information indicating at least one of the first feedback or whether the first feedback was received.

Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a base station of a wireless communications system to determine a configuration for a repeating device to forward signals to another device. In some examples, the configuration may be based on a number of repeating devices in the wireless communications system. The base station may also transmit a message for the repeating device to forward. In some examples, based on a buffering capability of the repeating device, the base station may transmit the message with a zero time offset relative to the control signaling. The repeating device may receive and process the control signaling and receive and buffer the message. In response to processing the control signaling, the repeating device may transmit the buffered message to another device. Implementing aspects of present disclosure may enable an increased efficiency of forwarding in wireless communications systems.
