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 communications are described. A base station may transmit a downlink message to a user equipment (UE). The base station may allocate a receive time window associated with receiving an uplink message from the UE responsive to the downlink message, wherein the receive time window is allocated based at least in part on a maximum propagation round trip time (RTT) associated with UEs within a coverage area of the base station and a frame size of the uplink message. The base station may monitor the receive time window for the uplink message from the UE. The base station may receive the uplink message from the UE during the receive time window.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for transmitting, from a user equipment (UE) to a base station, a report indicating a beamforming capability of the UE, receiving, from a base station, a configuration for a plurality of control resource sets (CORESETs) based at least in part on the report, selecting multiple CORESETs of the plurality of CORESETs, and monitoring the selected multiple CORESETs during a monitoring occasion. In some examples, the UE may also monitor one or more unselected CORESETs that have a quasi co-location relationship with one of the selected CORESETs.

Abstract: Aspects of the present disclosure relate to methods and apparatus for location encoding for secondary synchronization signals (SSS) to convey additional information, such as a current symbol number. According to aspects, a method is provided herein for wireless communications that may be performed, for example, by a base station (BS). The method generally includes selecting frequency resources to use for transmitting synchronization signals in a symbol of a frame, wherein the frequency resources are selected based on a mapping of frequency resources to a location of the symbol within the frame; and transmitting synchronization signals to at least one user equipment (UE) according to the mapping. As a result, the UE may receive synchronization signals, determine a location of the current symbol in a frame based on the mapping, and synchronize to the BS based on the determined location of the current symbol. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support different, or adjusted, random access channel (RACH) preamble formats for efficient use of shared RACH time-frequency resources. The described techniques provide for assigning different RACH preamble formats to wireless devices that have a higher link budget, whereupon the devices may transmit the different RACH preamble using the link budget available to them in one or more RACH transmission opportunities in the shared RACH time-frequency resources. Such methods, systems, and devices may allow for more RACH transmission opportunities, as well as less interference between RACH transmissions. For example, wireless devices communicating over a backhaul network may have a higher link budget than wireless devices communicating over an access network. As such, RACH preambles transmitted by the wireless devices communicating over the backhaul network may be shorter than RACH preambles transmitted by the wireless devices communicating over the access network.

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: Methods, systems, and devices for wireless communication are described. A base station may use quasi co-located antenna ports for transmission of synchronization signal(s)/reference signal(s) and paging signals. For example, the base station may use a first antenna port configuration for transmission of the synchronization/reference signal(s) and a second antenna port configuration for transmission of the paging signal (e.g., paging indicator, paging message, etc.). The base station may transmit an indication of the quasi co-located antenna ports. A user equipment (UE) may receive the synchronization signal and, based on the antenna ports being quasi co-located, receive the paging signal. In some examples, the UE may determine which receive beam to use to receive the paging signal based on the antenna ports being quasi co-located. In some aspects, the UE may use a reference signal transmitted on antenna ports that are quasi co-located with the paging signal antenna ports.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit downlink control information (DCI) messages to a user equipment (UE). A DCI message may be transmitted using a particular DCI format based on the type of control information included in the DCI message. In some cases, different types of control information may be transmitted using the same DCI format. In such cases, one or more bit fields in a DCI format may be useful to a UE for one type of control information but may not be useful to a UE for another type of control information. As described herein, in order to limit the overhead associated with control information transmissions, a base station may support techniques for utilizing these bit fields in a DCI format to transmit information corresponding to the type of control information being transmitted.

Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may use subframe configurations that include dynamically scheduled channel state information reference signal (CSI-RS) symbols. For example, a base station may identify a subframe configuration that includes one or more sets of CSI-RS symbols of a subframe. The base station may indicate to a UE whether sets of CSI-RS symbols may be enabled or disabled during the subframe. The UE may receive multiple CSI-RSs at different locations within the subframe as indicated by the base station, and transmit CSI feedback to the base station based on at least one of the received CSI-RSs. In some examples, multiple base stations may coordinate the use of subframe configurations that include CSI-RS symbols that may be enabled or disabled.
