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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may determine a first communication configuration for another wireless node. The wireless node may determine a second communication configuration, for the other wireless node, that is different from the first communication configuration, wherein the first communication configuration is a first timing reference and the second communication configuration is a second timing reference that is different from the first timing reference. The wireless node may communicate, with the other wireless node on a downlink, on an uplink, or on a sidelink, using the first communication configuration and the second communication configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A first network node may transmit, to a second network node, first information that is indicative of a bandwidth capability of the first network node and a first random access message. The second network node may transmit a second random access message in response to the first random access message and via a quantity of physical resource blocks (PRBs). The second random access message may indicate a time period for transmission, by the first network node, of a third random access message responsive to the second random access message. The time period may be based on a threshold time period associated with the bandwidth capability of the first network node, and the threshold time period may be based on the quantity of PRBs via which the second random access message is transmitted.

Abstract: A repeater BWP switching schedule is provided for a repeater that is responsive to a user equipment BWP switching schedule. Should the repeater support a plurality of active user equipments, the user equipment BWP switching schedule is a superset of the BWP switching schedule for each individual user equipment. The repeater BWP switching schedule may thus be more granular than the UE BWP switching schedule.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first signal from a base station indicating a set of available control channel monitoring sets to be used for control information. The UE may receive, over a default control channel monitoring set of the available control channel monitoring sets configured for the UE, a second signal from the base station activating at least one additional control channel monitoring set from the set of available control channel monitoring sets, the default control channel monitoring set comprising a subset of the set of available control channel monitoring sets. The UE may receive control information over the default control channel monitoring set and the at least one additional control channel monitoring set at least partially in response to receiving the second signal.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access (RACH) procedure based on a selected synchronization signal block (SSB). During this RACH procedure, a base station may transmit physical downlink control channel (PDCCH) messages for UE RACH message handling. To receive PDCCH signaling for RACH Messages 2, 3, or 4 (Msg 2/3/4), the UE may identify a set of time resources used by the base station for transmitting SSBs that are not quasi-co-located (QCL) with the selected SSB. The UE may identify a Msg 2/3/4 search space that does not overlap with this identified set of resources, and may monitor this identified search space. The search space may correspond to a modified remaining minimum system information (RMSI) search space indicated by the base station, or a valid RMSI search space not indicated by the base station.

Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability receives information for initial access using a first initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE transmits a random access message in an initial uplink BWP that is dedicated for the UEs having the first capability.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement. A base station provides information regarding what transmit beams are used to transmit different reference signal (RS) resources. In some cases, the information indicates whether a same transmit beam is used to transmit a set of RS resources (e.g., symbol, sub-symbol, or frequency resources) or whether different transmit beams are used to transmit the set of RS resources.

Abstract: Certain aspects of the present disclosure provide techniques communicating in a wireless network. In one embodiment, a method includes monitoring for a paging downlink control channel comprising downlink control information, wherein the downlink control information comprises a first short message; processing the first short message; determining if the control information further comprises scheduling information; processing the scheduling information if the downlink control information comprises scheduling information and the UE is not in a connected state; and ignoring the scheduling information if the downlink control information comprises scheduling information and the UE is in a connected state.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relay/repeater unit (RU) in an integrated access/fronthaul (IAF) network, receives, from an upstream node, a first physical downlink control channel (PDCCH) message associated with a scheduled physical uplink control or shared channel (PUXCH) transmission from a downstream node at a scheduled time, and relays or repeats the first PDCCH message to the downstream node. If the scheduled PUXCH transmission associated with the first PDCCH message is not received from the downstream node at the scheduled time, the RU sends a negative acknowledgement (NACK) message associated with the scheduled PUXCH transmission to the upstream node. The RU may also or alternatively generate a second PDCCH message associated with a rescheduled PUXCH transmission and send the second PDCCH message to the downstream node.
