Abstract: A method and apparatus enable sidelink resource management using a sidelink discovery signal. The method provides for determining a resource configuration for a sidelink discovery signal. The resource configuration provides one or more parameters for transmitting the sidelink discovery signal. The method also provides for measuring link quality between the UE and at least one candidate relay UE. Based on the measured link quality one of the candidate relay UEs is selected and serves as a relay UE.

Abstract: Aspects of the disclosure relate to beam sweeping with controllable reflective surfaces in the presence of co-located base stations of different network operators. A first base station that is co-located at a site with a second base station may perform a first beam sweep. The first beam sweep includes transmitting a plurality of directional beams. The first base station further transmits a control signal to a controllable reflective surface to control the controllable reflective surface to reduce a likelihood of a redirection of a directional beam of a potential second beam sweep by the second base station towards a user equipment associated with the second base station. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for duplex switching based on network power modes. A UE may receive a first indication that a first power mode of a network entity is associated with a first duplex type for the network entity and a second power mode of the network entity is associated with a second duplex type for the network entity. The first duplex type and the second duplex type may correspond to at least one of full-duplex communication or half-duplex communication. The UE may receive a second indication of a switch from the first power mode associated with the first duplex type to the second power mode associated with the second duplex type and communicate with the network entity based on the second power mode and the second duplex type for the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of parameters associated with a temporary bandwidth part (BWP) switch from a first BWP to a second BWP. The parameters may include a time duration for the temporary BWP switching procedure, a network antenna configuration for the second BWP, transmission parameters for communications scheduled in the second BWP, or a combination thereof. The UE may switch from the first BWP to the second BWP in accordance with the temporary BWP switching procedure and communicate with a network entity using the indicated parameters. For example, the UE may receive one or more downlink messages or transmit one or more uplink messages in accordance with the indicated parameters. Thereafter, the UE may switch from the second BWP to a third BWP in accordance with the temporary BWP switching procedure.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.
