    摘要： Apparatus and methods are provided RLF detection for SL-U communications. HARQ-based RLF detection and/or LBT failure -based RLF detection is performed (803) for SL-U RLF. HARQ based SL-U RLF procedure increases DTX for each PSSCH or PSCCH and disregards detected DTX on PSFCH or increases DTX for each PSFCH absence. In one embodiment, a DTX threshold value is modified. In one embodiment, the LBT based RLF procedure detects and reports an LBT failure for an RB set by the PHY layer; determines a consistent LBT, C-LBT, for the RB set based on a C-LBT failure threshold at the MAC layer and determines an RLF when all configured RB sets for the SL connection is determined to be C-LBT.

    摘要： Provided is a transmission bandwidth configuration method. The method includes: configuring a first channel bandwidth (CB) of a carrier; and in response to determining that the first CB is greater than a first preset bandwidth, configuring subcarriers in a first TBC according to a preset percentage X of the first TBC in the first CB and the first CB, so as to complete a subcarrier configuration in a transmission bandwidth configuration. The preset percentage X is within a range of [a preset lower limit value, a preset upper limit value], the preset lower limit value is greater than 90% and the preset upper limit value is less than 100%. Also provided is a transmitting node.

    摘要： Embodiments of this application relate to the field of communication technologies, disclose a bandwidth part switching method and an apparatus, to resolve problems of a large delay and large overheads in RRC-based BWP switching, DCI-based BWP switching, and timer-based BWP switching when a terminal device switches between two BWPs for a plurality of times. The method may include: A terminal device receives a first BWP hopping pattern from a network device. The first BWP hopping pattern includes one or more pieces of configuration information for switching between a first BWP and a second BWP. The terminal device switches between the first BWP and the second BWP based on the first BWP hopping pattern. The switching between the first BWP and the second BWP includes switching from the first BWP to the second BWP and switching from the second BWP to the first BWP. Embodiments of this application are used by a terminal device to perform a BWP switching process.

    摘要： A bandwidth mode indication method and apparatus are provided, and relate to the field of communication technologies. The method includes: A transmit end sends a first frame to a receive end, where the first frame includes a service field, the service field includes a first field, the first field indicates whether a bandwidth mode indication field carried in the first frame is allowed to indicate a target bandwidth mode, and the target bandwidth mode includes one or more of bandwidth modes other than 20 MHz, 40 MHz, 80 MHz, and 80+80 MHz or 160 MHz. Therefore, in a scenario in which a new bandwidth mode is introduced, two devices can negotiate a bandwidth mode based on the first frame according to the technical solutions provided in this application.
