Abstract: Methods, systems, and devices for wireless communications are described. Examples may include receiving, at a user equipment (UE) a random access channel (RACH) configuration message from a base station, where the message indicates a channel metric (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), or the like) and a threshold associated with the channel metric. The, UE may measure a reference signal (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), or the like) and select a RACH procedure based on comparing the measured channel metric to the threshold. For example, the UE may select a two-step RACH procedure if the measured channel metric satisfies the threshold specified in the configuration. In some cases, the UE may select a RACH procedure or a listen-before-talk (LBT) procedure based on a QoS parameter.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

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.

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: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability of the UE to support a restricted bandwidth for data signaling. The UE may receive an indication of a bandwidth part for control signaling and an indication of a set of frequency domain resources for the data signaling. The set of frequency domain resources may correspond to a subset of the bandwidth part in accordance with the restricted bandwidth. The UE may communicate the control signaling over the bandwidth part and data signaling over the set of frequency domain resources. In some cases, the bandwidth restriction may correspond to a bandwidth size for the set of frequency domain resources or a number of resource blocks in the set of frequency domain resources.
