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.

Abstract: A first apparatus may communicate with a user equipment (UE) through an active beam. The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.

Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices provide for identifying tone spacing for transmission or reception of signals. The identified tone spacing may vary depending on the transmission or reception spectrum band or signal type. Using the identified tone spacing, a number of repetitions or a number of symbols for transmission or receiver algorithm of a signal may be determined.
