Abstract: An integrated access backhaul (IAB) node with an unknown position may use the mobile terminated (MT) function to send or receive reference signals to or from multiple base stations in one or more positioning sessions for positioning of the IAB node. The distributed unit (DU) function may be used additionally, or alternatively, to send or receive reference signals to or from multiple nodes, e.g., user equipments (UEs) or MT functions of downstream IAB nodes. Positioning measurements from the reference signals may be sent to a location server, which may determine the position of the IAB node. The location server may further receive an indication of the mobility of the IAB node, which may be used for positioning of UEs, e.g., by excluding information about a mobile IAB node during positioning.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a downlink beam in uplink control information of a random access message, wherein the downlink beam is different from a default beam corresponding to a preamble of the random access message and a random access occasion in which the random access message is transmitted, or wherein the downlink beam is selected from a set of multiple downlink beams corresponding to the random access occasion. The UE may monitor for at least one of a random access response or a downlink communication subsequent to the random access response using the downlink beam indicated in the uplink control information. Numerous other aspects are provided.

Abstract: Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may transmit, to a second UE, first control information indicating a first transmission configuration indicator (TCI) state for use in sidelink communications between the first UE and the second UE. The first UE may receive, from the second UE, second control information indicating a second TCI state for use in sidelink communications between the first UE and the second UE, where a first application time of the first TCI state conflicts with a second application time of the second TCI state. The first UE may select, in accordance with one or more rules for resolving sidelink TCI state conflicts, one of the first TCI state or the second TCI state as a selected TCI state. Accordingly, the first UE may communicate with the second UE in accordance with the selected TCI state.

Abstract: Certain aspects of the present disclosure provide techniques for communicating a dynamically scheduled transmission that overwrites a transmission in a semi-static scheduling occasion. A method performed by a user equipment (UE) includes receiving a first control message, activating a first semi-static scheduling configuration and a second semi-static scheduling configuration for full duplex communication, wherein: the first semi-static scheduling configuration comprises a semi-persistent scheduling (SPS) occasion and the second semi-static scheduling configuration comprises a configured grant (CG) occasion. The method may further include receiving a second control message dynamically scheduling a transmission that overwrites a downlink transmission in the SPS occasion or an uplink transmission in the CG occasion and taking one or more actions to communicate at least the transmission that overwrites the downlink transmission in the SPS occasion or the uplink transmission in the CG occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may send coupled configured grants to a transmitter user equipment (UE) and a receiver UE, respectively. For example, when transmitting a pair of configured grants that includes a first configured grant sent to a first UE and a second configured grant sent to a second UE, the base station may include an indication in each of the configured grants that sidelink semi-persistent scheduling resources are activated or deactivated. Additionally, the configured grants may indicate which UE is a receiver and which UE is a transmitter. For instance, the first configured grant may indicate that a first UE is to be the transmitter and a second configured grant indicate that a second UE is to be the receiver.

Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media for reducing latency associated with performing some operations that use a reference signal. To illustrate, a user equipment (UE) may receive a reference signal and then may receive a message indicating one or more of an update of a transmission configuration indicator (TCI) state of the UE or a change in designation of a path loss reference signal (PL-RS) measured by the UE. If the reference signal is received within a threshold time period of receiving the message (or vice versa), the UE may perform the update or the change in designation of the PL-RS using one or more parameters determined using the reference signal.
