Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a host device may determine a pool of preconfigured resources for discovery. The preconfigured resources are designated for one or more of: a discovery preamble, a query signal, a discovery message, and a random access preamble. The host device may transmit the discovery preamble on one or more resources designated for the discovery preamble. A client device may receive the discovery preamble and determine that the client device is interested in receiving information regarding the host device. The client device may transmit a query signal if interested. The host device may determine whether the query signal is received on a resource designated for the query signal in response to the discovery preamble. The host device may transmit a discovery message in response to receiving the query signal.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for determining a maximum transport block size. In certain aspects, a method comprises receiving, from a user equipment (UE), information indicative of a size of a buffer at the UE for storing data received from the BS. The method further includes determining a maximum transport block size based on the size of the buffer at the UE and a number of hybrid automatic repeat request (HARQ) processes used by the BS to send data to the UE. The method further comprises transmitting a transport block with a size not exceeding the maximum transport block size to the UE.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless node may receive a first scheduling command identifying a first resource allocation via a first link, may determine a second resource allocation based at least in part on the first resource allocation and a resource allocation policy, may transmit a second scheduling command identifying the second resource allocation via a second link, and may communicate network traffic on the first link and the second link using the first resource allocation and the second resource allocation, respectively. Numerous other aspects are provided.

Abstract: Various features related to using a multi-port synchronization signal as reference for demodulating a multi-port broadcast channel are described. In an aspect, a synchronization signal, e.g., SSS, may be repurposed to serve as a demodulation reference for a downlink channel, e.g., PBCH, thereby obviating the need for a base station to send an additional reference signal for PBCH demodulation. A base station may select two or more logical antenna ports to transmit a synchronization signal, transmit the synchronization signal from the selected two or more logical antenna ports, and transmit information on the PBCH, from at least the selected two or more logical antenna ports. A UE may receive the synchronization signal from the two or more logical antenna ports at the base station, receive information on the PBCH from the at least the two or more logical antenna ports, and demodulate the information based on the received synchronization signal.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity receives measurement reports that indicate a non-reciprocity condition between link directions (e.g., as part of a multi-round trip time (RTT) position estimation session). In an aspect, the position estimation entity transmits request(s) to retrieve non-reciprocity source information, which may be used in position estimation derivation (e.g., to correct for error due to the non-reciprocity). In an aspect, the request(s) may be transmitted to a target UE and/or a wireless node involved in the position estimation session (e.g., serving gNB or TRP, another UE, etc.).

Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: This disclosure provides methods, components, devices, and systems for optimizing energy efficiency and network performance in cellular networks through dynamic adaptation of transmission parameters for synchronization signal blocks (SSBs) and system information block type 1 (SIB1) transmissions initiated by user equipment (UE) requests. Some aspects more specifically relate to providing UE-assisted information over an uplink wake-up signal (UL-WUS) to optimize support of on-demand SSBs or SIB1s. In some examples, a UE sends an uplink signal to a network entity requesting transmission of at least one of an SSB or an SIB1, with the uplink signal indicating a transmission parameter for the SSB or the SIB1, such as transmission power or repetition factor. In response to the uplink signal, the network entity sends the SSB or the SIB1 associated with the transmission parameter based at least in part on the uplink signal, resulting in improved energy efficiency and network performance.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via a cell with a physical cell identity, first signaling that indicates a first physical cell identifier (PCI) value of a PCI sequence and a code value associated with the PCI sequence for the cell. The UE may receive, via the cell with the physical cell identity, second signaling that indicates a second PCI value of the PCI sequence and the code value associated with the PCI sequence for the cell. The UE may perform, via the cell with the physical cell identity, one or more wireless communications in association with determining the physical cell identity of the cell based on the code value and the PCI sequence comprising the first PCI value and the second PCI value (which may be a function of the first PCI value and the code value).
