Abstract: Aspects of the disclosure generally relate to wireless communication. In some aspects, a wireless node may identify a first set of synchronization signal blocks (SSBs), within a synchronization signal (SS) burst set, that are used to indicate random access channel (RACH) occasions for a first wireless link type, the SS burst set including a second set of SSBs used to indicate RACH occasions for a second wireless link type; and transmit a RACH message in a RACH occasion corresponding to an SSB included in the first set of SSBs. In some aspects, a wireless node may configure an SS burst set to include a first set of SSBs to be used to indicate RACH occasions for a first wireless link type, and a second set of SSBs to be used to indicate RACH occasions for a second wireless link type; and transmit the SS burst set. Other aspects are provided.

Abstract: Repetitive PDCCH may be utilized to extend control channel coverage. The PDCCH may be configured to repeat in adjacent or non-adjacent slots per monitoring occasion of corresponding search space. The PDCCH may carry control information such as a grant that schedules a channel for a wireless device, such that the wireless device receives instructions for scheduling a channel at a scheduled slot. The apparatus may receive control information in a repetitive PDCCH within a set of slots. The repetitive PDCCH schedules a channel for reception or transmission by the UE. The apparatus may determine a scheduled slot index for the channel scheduled by the repetitive PDCCH. The apparatus may communicate the channel at the determined scheduled slot index and based on the received control information in the repetitive PDCCH. The channel may be a PDSCH, a PUSCH, or may carry A-CSI-RS.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive information that identifies a time offset associated with backhaul physical random access channel (PRACH) resources. The time offset may be different from a time offset that is identified based at least in part on a PRACH configuration index The wireless communication device may identify a set of backhaul PRACH resources based at least in part on the time offset. The wireless communication device may transmit a RACH transmission using the identified set of backhaul PRACH resources. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive (or a base station may transmit) information identifying a selected configuration for a discontinuous reception (DRX) wakeup signal (WUS) for the user equipment, wherein the selected configuration is one of a plurality of configurations; and selectively monitor a wakeup signal resource according to the selected configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit (or a base station may receive) a beam failure recovery (BFR) request based at least in part on detecting a beam failure while the user equipment is in a discontinuous reception (DRX) mode; and the user equipment may receive (or the base station may transmit) a response to the BFR request, wherein the response uses a particular structure based at least in part on the beam failure occurring during the DRX mode. Numerous other aspects are provided.

Abstract: A relay node at a base station may configure a first radio channel with a first priority and a first priority ID, and configure a second radio channel with a second priority and a second priority ID. The base station may configure a third radio channel with a first bearer ID and a first mapping to the first priority, and configure a fourth radio channel with a second bearer ID and a second mapping to the second priority. The relay node may forward packets from the third radio channel to the first radio channel based on the first mapping and insert the first priority ID into a header in the packets. The relay node may forward packets from the fourth radio channel to the second radio channel based on the second mapping, and insert the second priority ID into a header in the packets.

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 subarrier 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.
