Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit a set of first values indicating a first estimated value at the first node and a first reliability value associated with the first estimated value, the set of first values being based at least in part on channel state information (CSI) associated with the first node and a set of user equipments (UEs). The first node may receive, from a set of second nodes, a set of second values indicating a second estimated value at the second node and a second reliability value associated with the second estimated value. The first node may transmit, to the set of second nodes, a set of third values indicating a third estimated value at the first node and a third reliability value associated with the third estimated value. Numerous other aspects are described.

In-network distributed processing for precoding and linear detection

Disclosed are techniques for wireless communication. In an aspect, a base station may determine a transmit power to be used by a downstream node or an amplification gain to be used by the downstream node when relaying or repeating messages to a target node. The base station may transmit, to the downstream node, a message intended for the target node, the message having an indicated transmit power, wherein the message intended for the target node is transmitted by the base station using an actual transmit power. In some aspects, the indicated transmit power is the transmit power to be used by the downstream node, so that when the message intended for the target node is repeated by the downstream node, the indicated transmit power of the repeated message matches the actual transmit power of the repeated message.

Measurement and power control in integrated access fronthaul networks

A relay supporting multiple relay modes is provided. The relay transmits capability information to a base station, the capability information indicating support for a first relay mode and a second relay mode. The relay determines a mode of operation, either on its own or based on an indication of a mode of operation from the base station, wherein the mode of operation comprises the first relay mode or the second relay mode. The relay communicates with at least one of the base station or another wireless device based at least in part on the determined mode of operation.

Remote unit with a configurable mode of operation

Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support power saving of wireless repeaters. Generally, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, etc.) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a slow state (e.g., according to a relatively long monitoring periodicity). Upon detection of possible UE attachment to the base station (e.g., upon detection of a random access channel (RACH) message), the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a relatively short, or more frequent, monitoring periodicity).

Power saving of smart repeaters

Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., user equipment (UE), base station) may determine a block fading pattern associated with a communication link between the first wireless device and a second wireless device, the block fading pattern including a pattern of fluctuating channel quality. The first wireless device may selectively adjust one or more communications parameters for communicating with the second wireless device over the communication link based on the determined block fading pattern. The first wireless device may then communicate with the second wireless device over the communication link based at least in part on the one or more adjusted communications parameters.

Estimation and utilization of a block fading wireless channel

Aspects relate to exchanging beam-related information for a repeater device. A network access node may configure a repeater device to transmit multiple synchronization signal blocks using different beams. The network access node may determine the number of beams that the repeater device can use for its operations. A repeater device may indicate how many beams the repeater device supports, how many antenna arrays it has, and a mapping of beam indices to antenna array indices. A repeater device may indicate which beam pairs cannot be used for simultaneous transmission and/or reception and/or which beam groups can be used for simultaneous transmission and/or reception. A network access node may determine which beam pairs the repeater device cannot use for simultaneous transmission and/or reception and/or which beam groups the repeater device can use for simultaneous transmission and/or reception based on signal measurements and/or beam configuration feedback from the repeater device.

Information for wireless communication repeater device

A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a repeater node. The apparatus may receive, at one or more first antennas of the node, a first signal via at least one first beam. The apparatus may measure, at one or more third antennas of the node, at least one of a power or a quality of at least one third beam. The at least one of the power or the quality of the at least one third beam may be measured at a same time as the first signal is received. The apparatus may forward, at one or more second antennas of the node, the first signal via at least one second beam.

Repeaters capable of simultaneous repeating operation and power detection

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive configuration information associated with configuring involvement of the repeater in an access procedure. The repeater may generate a signal associated with the access procedure based at least in part on the configuration information. The repeater may transmit the signal to a wireless communication device based at least in part on the configuration information and other information associated with the access procedure. Numerous other aspects are described.

Access procedure configuration of a millimeter wave repeater

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may identify one or more parameters for mechanical beam steering. The repeater may perform mechanical beam steering based at least in part on the one or more parameters. Numerous other aspects are provided.

Repeater mechanical beam steering

Aspects described herein relate to establishing a control connection with at least a first node for receiving control information for providing a repeater function for two or more upstream nodes, communicating control information over the control connection from at least the first node, and providing, based on the control information, the repeater function between at least a first upstream node of the two or more upstream nodes and at least one downstream node and between at least a second upstream node of the two or more upstream nodes and the at least one downstream node or at least another downstream node.

Techniques for using repeaters with multiple upstream nodes in wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may receive configuration information associated with configuring involvement of the repeater in an access procedure; receive a signal associated with the access procedure from a first wireless communication device; and forward the signal associated with the access procedure to a second wireless communication device based at least in part on the configuration information and other information, associated with the access procedure, received by the repeater. Numerous other aspects are provided.

Aspects relate to an array antenna and communication using the array antenna. In some examples, the array antenna includes a first array of antenna elements arranged according to a first circle and a second array of antenna elements arranged according to a second circle, where the first circle and the second circle are concentric circles. In some examples, the first array of antenna elements is arranged with an angular offset with respect to the second array of antenna elements. For example, a first radius associated with a first antenna element of the first array of antenna elements may be offset at an angle with respect to a second radius of a second antenna element of the second array of antenna elements.

Circular array antenna with angular offset

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater node may receive, from a control node, a configuration that indicates at least one of a time domain reconfiguration or a frequency domain reconfiguration. The repeater node may receive a first signal. The repeater node may process the first signal based at least in part on the configuration. The repeater node may generate at least one second signal based at least in part on the processed first signal. The repeater node may transmit the at least one second signal. Numerous other aspects are provided.
