A wireless device sends, to an access and mobility management function (AMF), a request for a multimedia priority service (MPS). The wireless device receives, from the AMF, a connection capability indication indicating network support for a connection of the wireless device for the MPS. The wireless device sends to the AMF, based on the connection capability indication, a request for a packet data unit (PDU) session establishment.

Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.

Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a first band and decodes the PPDU. The PPDU includes a control field and a data field. The first band is an 80 MHz band including first and second 20 MHz subchannels and a first 40 MHz subchannel. When the first 20 MHz subchannel is punctured, the second 20 MHz subchannel includes a first multi-RU in which first and second 26-RUs, 52-RUs, and 106-RUs are aggregated. The first 40 MHz subchannel includes a 484-RU. The data field is received through a second multi-RU in which the first multi-RU and the 484-RU are aggregated.

A resource unit combination indication method and a communication apparatus are provided. The resource unit combination indication method includes: A transmit end generates a physical layer protocol data unit (PPDU), and sends the PPDU. The PPDU includes a resource unit allocation subfield. The resource unit allocation subfield indicates a multi-resource unit (MRU) to which a 242-tone resource unit (RU) corresponding to the resource unit allocation subfield belongs, and further indicates a quantity of user fields corresponding to the resource unit allocation subfield. According to the application, one or more users may be indicated to use a plurality of contiguous or noncontiguous RUs for data transmission, to improve RU allocation flexibility of a system and spectrum utilization of the system.

A codebook feedback method includes a network device sending a first indication information to a terminal device, wherein the first indication information is used to indicate at least one set of basis vector sets, and the at least one set of basis vector sets includes a frequency domain basis (FD basis) set or a spatial domain-frequency domain-basis (SD-FD-basis) set.

A communication control method according to a first aspect is a method executed by a user equipment. The communication control method includes the step of measuring a residence time of unsent data to be transmitted by the user equipment to a base station via a logical channel and the step of allocating, based on the residence time, a resource for data transmission to the logical channel.

A relay device first receives a data packet from a network device through a first link, and sends the data packet to user equipment through a second link. A protocol stack of the relay device consists of a physical layer, a media access control layer, and a segmentation function or a resegmentation function of a radio link control layer; a protocol stack of the relay device consists of a physical layer, a media access control layer, a segmentation function or a resegmentation function of a radio link control layer, and an adaptation layer; or a protocol stack of the relay device consists of a physical layer and a hybrid automatic repeat request function of a media access control layer. The first link is a wireless communication link between the network device and the relay device, and the second link is a wireless direct communication link between the relay device and the user equipment.

Embodiments of this application provide a radio bearer configuration method, an apparatus, and a system. A multicast radio bearer used to receive a multicast/broadcast service is established between a terminal and a base station, to reduce complexity of processing the data of the multicast service by the base station. This solution includes: A base station receives a first request message, where the first request message requests to add a first terminal to a multicast/broadcast service; and the base station sends configuration information of a multicast radio bearer to the first terminal based on quality of service QoS flow information of the multicast/broadcast service. The configuration information is used to configure the multicast radio bearer, the multicast radio bearer is used to transmit data of the multicast/broadcast service to a terminal that has joined the multicast/broadcast service, and the terminal that has joined the multicast/broadcast service includes the first terminal.

A method, apparatus, and device for determining protocol architecture are provided. The method includes: receiving a target message from a second device, where the target message carries first information; and determining, based on the first information and second information, whether to establish a communication connection to the second device, where the first information is used to indicate architecture information of a first protocol architecture that the second device currently supports and/or prefers, and the second information is used to indicate architecture information of a second protocol architecture that a first device currently supports and/or prefers.
