Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may monitor for transmissions from multiple base stations. For example, a wireless repeater may communicate with a first base station and forward transmissions from the first base station to various user equipment (UEs). Such transmissions may include transmitting synchronization signal blocks (SSBs) for the first base station. The first base station may instruct the wireless repeater to monitor for SSBs from other base stations, where the wireless repeater may indicate the monitoring results in a report to the first base station. Based on the report, the first base station may transmit an indication of a beam pattern to the wireless repeater. The wireless repeater may use the beam pattern for repeating transmissions of SSBs received from the first base station, SSBs received from the second base station, or any combination thereof.

Abstract: Various aspects of the disclosure relate to reporting a power limit along with an indication of at least one constraint upon which the power limit is based. In some aspects, the constraint is a radio frequency (RF) exposure constraint. For example, a power headroom limit calculated by a first apparatus may be constrained by a specific absorption rate (SAR) limit or a maximum permissible exposure (MPE) limit. The first apparatus may thus report to a second apparatus the current power headroom limit of the first apparatus along with an indication of whether the power headroom limit is constrained by an SAR limit or an MPE limit (e.g., as opposed to being constrained by a maximum transmit power limit). The second apparatus may then schedule the first apparatus taking into account the power headroom limit and the corresponding constraint (e.g., maximum power or SAR/MPE).

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless nodes that relay directional wireless signals). For example, by adding even limited capability to buffer digital samples, repeater functionality may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: Wireless communications systems and methods are provided for a base station (BS) to configure initial sweeping with one or more repeaters. For example, a BS may determine a sweeping configuration based on any combination of measurement reports from the repeater and/or received information on the capabilities or category of the repeater. Capabilities can include codebook information, repeater's architecture, beam switching latency, synchronization level, and/or the like. Measurement reports may be transmitted by and/or between a repeater to a BS following an initial connection setup between a repeater and a BS. Other aspects and features are also claimed and described.

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: A base station may transmit scheduling information comprising one or more first downlink messages to a first user equipment (UE) in a first beam. The base station may transmit one or more second downlink messages to a second UE in a second beam. In response to the transmission of the one or more first downlink messages, the base station may receive one or more first uplink control messages from the first UE in a time slot. In response to the transmission of the one or more second downlink messages, the base station may receive one or more second uplink control messages from the second UE in the same time slot. The one or more second uplink control messages may be frequency-orthogonal or spreading code-orthogonal to the one or more first uplink control messages.

Abstract: A first apparatus may send, to a base station in a first carrier frequency, a request associated with determination of a first beam used for communication between the base station and the UE. The first apparatus may communicate with the base station in a second carrier frequency based on the request associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency. A second apparatus may receive, from a base station in a first carrier frequency, a message associated with determination of a first beam used for communication between the base station and the UE. The second apparatus may communicate with the base station in a second carrier frequency based on the message associated with the determination of the first beam, the first carrier frequency being different from the second carrier frequency.

Abstract: Methods, systems, and devices for wireless communication are described. Synchronization signals may be transmitted using a set of phase offsets over different component carriers or using a single component carrier for each antenna port. For example, a base station may identify a set of synchronization signals (e.g., a set of primary synchronization signals (PSSs)) to be transmitted over one or multiple component carriers. In some cases, each PSS may be associated with a different component carrier, and the base station may apply a different phase offset to each PSS when transmitting the set of PSSs on the component carriers. In some examples, the base station may transmit the PSSs on the component carriers using a different antenna port for each component carrier.

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.
