According to certain embodiments, a method in a network node (100A) for determining spectrum utilization for a plurality of numerologies transmitted within an allocated bandwidth includes selecting one or more of the plurality of numerologies. For each of the one or more selected numerologies, a spectrum utilization is determined. The spectrum utilization is based on the spectrum utilization that would be achieved if the selected numerology was transmitted across the allocated bandwidth. A physical resource block (PRB) allocation is calculated based on the allocated bandwidth and the spectrum utilization.

A method for a first device to perform wireless communication and a device supporting same. The method may include the steps of: receiving, from a base station, a time division duplex uplink-downlink (TDD UL-DL) configuration including information related to a UL resource; receiving, from the base station, information related to the start of sidelink (SL) symbols, information related to the number of the SL symbols, and a bitmap indicating one or more slots included in an SL resource pool; and determining the SL resource pool.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station to transmit a feedback configuration to a user equipment (UE) indicating a subcarrier spacing and a length of a cyclic prefix (CP) that the UE is to use to transmit feedback associated with a second frequency band (e.g., a high frequency band) using a first frequency band (e.g., a low frequency band). The UE may monitor the second frequency band for downlink messages transmitted by the base station and transmit a feedback message accordingly using the indicated subcarrier spacing and applying a CP having the indicated length.

A method performed by a terminal in a communication system is provided. The method includes identifying a first physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH), and a second PDSCH without a corresponding PDCCH; identifying that the first PDSCH and the second PDSCH are overlapped in time; and decoding the first PDSCH on a basis that the PDCCH scheduling the first PDSCH ends at least 14 symbols before the starting symbol of the second PDSCH.

A method and a device in a communication node used for wireless communications is disclosed in the present disclosure. The communication node first receives first information and second information; and transmits a first radio signal in a first time window; and then transmits a second radio signal; the first information is used to determine a target time window, the second radio signal occupies a second time window in time domain, and the second information is used to determine at least one of whether the second time window belongs to the target time window or a relative position relationship between the second time window and the target time window; an end of the first time window is earlier than a start of the target time window. The present disclosure helps improve the utilization ratio of resources in Grant-Free transmission.

A positioning signal processing method includes receiving positioning reference signal (PRS) configuration information from a positioning device. A PRS is received as a PRS resource set. Each PRS resource set includes one or more PRSs. One access network device corresponds to one or more PRS resource sets. The positioning signal processing method further includes determining PRS time domain information based on the PRS configuration information. The time domain information includes a periodicity (P) of the PRS and a symbol length of the PRS in the P. The positioning signal processing method further includes receiving a plurality of PRSs based on the PRS time domain information.

Disclosed are an information sending method, information receiving method, apparatus, and device. The information sending method includes: receiving a physical sidelink feedback channel (PSFCH); determining a first duration; and sending a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) not earlier than a first moment, where the first moment is a moment the first duration after an end moment of receiving the PSFCH. A terminal device does not send the PUCCH or the PUSCH before the moment the first duration after the end moment of receiving the PSFCH. Because the terminal device can determine the first duration, it is ensured that the terminal device may have sufficient time to process the PUCCH or the PUSCH. The PUCCH or the PUSCH may be used to carry sidelink hybrid automatic repeat request (HARQ) information, and the HARQ information may be generated based on the received PSFCH.

A configuration information indication method and apparatus, applicable to systems such as a vehicle to everything V2X communication system and a vehicle-to-vehicle V2V communication system, to resolve a problem that SL transmission causes interference to DL transmission due to relatively poor indication accuracy of UL transmission time in the conventional technology. The method includes: receiving an uplink-downlink time division duplex TDD configuration from a network device; determining, based on first periodicity information included in the uplink-downlink TDD configuration, a first subcarrier spacing SCS corresponding to the first periodicity information, where the first SCS is used to indicate a sidelink SL reference SCS; and sending indication information to a second terminal device based on the uplink-downlink TDD configuration and the first SCS, where the indication information is used to indicate uplink UL transmission time corresponding to the first periodicity information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit a first set of synchronization signal block (SSB) burst sets with a first set of SSB parameters; and transmit a second set of SSB burst sets with a second set of SSB parameters, wherein the first set of SSB burst sets and the second set of SSB burst sets are transmitted in a common carrier. In some aspects, a user equipment (UE) may receive at least one SSB of the first set of SSB burst sets or the second set of SSB burst sets. Numerous other aspects are provided.

A method of operating a radio node in a wireless communication network in which the method includes performing cell search on a first frequency range based on at least a first selected bandwidth of a set of signaling bandwidths, the set comprising at least a first signaling bandwidth and a second signaling bandwidth.
