Abstract: Disclosed are techniques for transmitting reference signals (RS) for positioning. A method comprises transmitting or providing an instruction to transmit a first set of RS to a user equipment (UE) in accordance with a first set of RS transmission parameters, receiving a report containing information indicating whether a measurement performed by the UE is limited by a signal-to-noise ratio (SNR) of the first set of RS or a bandwidth of the first set of RS, determining a second set of RS transmission parameters using the received report, wherein the second set of RS transmission parameters is different from the first set of RS transmission parameters, and transmitting a second set of RS to the UE in accordance with the second set of RS transmission parameters, or providing the second set of RS transmission parameters to a base station.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) blocks in which synchronization signals and broadcast channel transmissions may be transmitted. Broadcast channel transmissions may be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. Broadcast channel transmissions may be transmitted in a subset of SS block time resources, and synchronization signals may be transmitted in another subset of SS block time resources. Reference signals may be transmitted using tones within the broadcast channel time resources, and may be transmitted at a higher density for portions of the broadcast channel transmission bandwidth that are outside of the SS transmission bandwidth. Waveforms for reference signal transmissions, and information provided by reference signal transmissions may be provided.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to interpreting a timing advance (TA) command for members of a timing advance group (TAG), such as different uplink component carriers and/or different bandwidth parts, having different numerologies, such as different subcarrier spacing (SCS). A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a TA command. The UE interprets the TA command differently for different members of a same TAG, associated with different numerologies. The UE applies a timing adjustment when transmitting an uplink transmission to the BS based, at least in part, on the interpretation.

Abstract: Methods, systems, and devices for wireless communication are described. In particular, a backhaul network that may be established between access nodes and/or base stations is shown and described. To support communications via the backhaul network, a synchronized frame structure and unique network topologies may be established. Resources may be allocated to different wireless communication links based on the synchronized frame structure. Occupancy/availability indications are shown and described, which enable the local redistribution of resources to account for variations in signal quality and/or variations in traffic experienced by the backhaul network.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify that data is available to be transmitted to a user equipment (UE) that is operating in a discontinuous reception mode. The base station may transmit, based at least in part on identifying that the data is available to be transmitted to the UE, a wakeup message to the UE using a first transmit beam. The base station may initiate a beam management procedure based at least in part on identifying that the data is available to be transmitted to the UE, to identify a second transmit beam for the base station to use to transmit the available data to the UE, wherein the second transmit beam comprises a narrower beam width than the first transmit beam.

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: 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: Systems and methods for determining round trip time (RTT) includes a second node, which receives a first signal from a first node at a first time, determines a timing advance based on a first estimated channel response for the first signal, and transmits at a second time, a second signal to the first node, wherein the second time occurs after the first time by an amount of a pre-specified delay for RTT estimation minus the timing advance. The first node transmits the first signal to the second node at an initial time, receives the second signal from the second node, and determines a timing statistic from a second estimated channel response for the second signal, the timing statistic estimated at a third time. The first node determines the RTT as the third time minus the initial time minus the pre-specified delay for RTT estimation.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether to perform a beam pair refinement procedure with regard to the UE and a base station; and/or transmit, to the base station, information regarding whether to perform the beam pair refinement procedure. In some aspects, a base station may receive, from a UE, information regarding a beam pair refinement procedure with regard to the UE; and/or perform the beam pair refinement procedure based at least in part on the information. Numerous other aspects are provided.
