This application provides a resource unit combination indication method and a communications apparatus. The method includes: determining a physical layer protocol data unit PPDU, where the PPDU includes a signal field, the signal field includes a resource unit allocation subfield and a combination indication corresponding to the resource unit allocation subfield, the resource unit allocation subfield indicates a plurality of resource units, and the combination indication indicates combination information of the plurality of resource units; and sending the PPDU. The method provided in this application can support one or more users in transmitting data by using a plurality of contiguous or discontiguous RUs, and indicate a combination status of the plurality of RUs to the user.

A bearer establishment method, a configuration method, a terminal, and a network side device are provided. The bearer establishment method includes: receiving first information; and establishing, according to a first Layer 2 (L2) configuration parameter of a first Multicast Broadcast Service (MBS), a bearer corresponding to the first MBS, where the first L2 configuration parameter is determined based on the first information.

This application provides a method and a corresponding apparatus. One example method includes: A transmitting side receives an RLC status report from a receiving side, where the RLC status report includes at least one piece of status information, each of the at least one piece of status information indicates one or more receiving statuses of one or more consecutive RLC service data units (SDUs) that are not successfully received, and the at least one piece of status information is sequentially sorted in ascending order of RLC SDU sequence numbers (SNs) in the RLC status report; and if the last piece of status information in the RLC status report indicates that a part of data of a first RLC SDU is lost, the transmitting side determines, based on the RLC status report, whether a receiving status of the first RLC SDU is completely reflected in the RLC status report.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to trigger frame and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) PPDU from a wireless station (STA), where the trigger frame carries RU allocation information indicating a number (N) of tones allocated for the STA and carries tone distribution information indicating whether the N tones are allocated for a contiguous transmission or a distributed transmission. In some other implementations, an AP or a STA may transmit a PPDU carrying distributed signaling information indicating whether the PPDU is transmitted as a contiguous transmission or a distributed transmission.

The present application relates to devices and components including apparatus, systems, and methods for beam failure recovery operations in wireless communication systems.

The present disclosure relates to a method of processing signals by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a data signal including a data unit for a multicast/broadcast service (MBS) based on a control signal addressed with a Group-Radio Network Temporary Identifier (G-RNTI) from a network; identifying a logical channel for the MBS among two or more logical channels, based on the G-RNTI and a logical channel identifier; and transferring the data unit for the MBS to the identified logical channel.

Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as an on-off keying (OOK) signal. Logic may generate and receive a wake-up preamble that signals a high data transmission rate with respect to data rates defined for WUR packet transmissions. Logic may generate or receive a preamble that signals a rate of transmission of the WUR packet as 250 kilobits per second. Logic may transmit or receive bits of the wake-up preamble as two microsecond orthogonal frequency-division multiplexing (OFDM) based pulses, wherein each two microsecond OFDM based pulse is based on a 32-point Fast Fourier Transform (FFT) in a 20 Megahertz (MHz) bandwidth, with a subcarrier spacing of 625 Kilohertz (KHz) to produce six subcarriers in a four MHz bandwidth.

A unified solution to support all PCell, SCell, and per-TRP based beam failure recovery (BFR) procedure is proposed, with less standard impact and reduced latency. In a first novel aspect, a set of reference signals (RSs) for BFD is configured for each BWP of a serving cell, and a maximum number of BFD RSs (N) per TRP for each BWP of a serving cell is configured. In a second novel aspect, for single DCI multi-TRP, the BFD RSs can be updated via MAC CE to reduce latency. In a third novel aspect, new RRC parameters for BFD RSs and candidate beam RSs are configured, with different sets of SSB/CSI-RS resources associated to each TRP. Specifically, an additional lists of SSB/CSI-RS resource set is defined for each corresponding TRP.
