Abstract: This application provides a communication method, apparatus, and system, and is applied to the field of communication technologies. The communication method provided in this application includes: A first terminal apparatus receives first sidelink control information from a second terminal apparatus, where the first sidelink control information indicates a second resource. The first terminal apparatus excludes or selects the second resource based on a first condition, where the selecting the second resource includes: selecting the second resource as an available resource for transmitting sidelink information of the second terminal apparatus; or selecting a resource in a slot in which the second resource is located as an available resource for transmitting sidelink information of the first terminal apparatus. This application provides a solution of how to select a resource in a COT sharing scenario.

Abstract: A communication method includes determining, at a first time, that listen before talk (LBT) on a first resource meets a consistent LBT failure. The communication method also includes determining a first duration. The communication method further includes determining a first resource set from a resource selection window based on the first time and the first duration. A resource in the first resource set is used for sidelink communication.

Abstract: A communication method, apparatus and non-transitory computer-readable storage medium are provided in this application. A first terminal obtains first information, where the first information indicates a fourth resource to be used by the first terminal apparatus in a first communication system. The first terminal excludes the fourth resource and a fifth resource, the fifth resource including a same resource as the fourth resource in time domain and including different subchannels from the fourth resource. The first terminal determines a sixth resource from a resource excluding the fourth resource and the fifth resource and transmits sidelink information on the sixth resource in a second communication system. When excluding resources, the first terminal excludes not only the fourth resource, but also the fifth resource, to avoid a case that a resource selected by the first terminal conflicts with a reserved resource for a terminal in the first communication system.

Abstract: A sidelink communication method and an apparatus are disclosed, and are applicable to fields such as V2X, vehicle-to-everything, assisted driving, or autonomous driving. The communication method includes: A first terminal device determines a resource pool corresponding to each of at least two carriers in a first carrier set, where a sidelink synchronization signal block S-SSB resource is configured on each carrier in the first carrier set, and any resource in a resource pool corresponding to any carrier in the first carrier set does not overlap, in time domain, an S-SSB resource on any carrier in a second carrier set; and the first terminal device selects at least one first resource from the resource pool to send data.

Abstract: A resource determining method and an apparatus are provided. The method includes: A first terminal device determines first channel occupancy time COT reservation information of the first terminal device and one or more pieces of second channel occupancy time COT reservation information of a second terminal device. The first terminal device performs resource exclusion on a first COT candidate resource set based on the first COT reservation information and the one or more pieces of second COT reservation information, to obtain an updated first COT candidate resource set, where the updated first COT candidate resource set is used by the first terminal device and/or a third terminal device for sidelink transmission.

The method includes: A first terminal device performs listen before talk LBT; and the first terminal device sends sidelink information in a first time unit, where the first time unit includes a time unit in which the first terminal device successfully performs the LBT or a next time unit of the time unit in which the first terminal device successfully performs the LBT.

Abstract: A communication method and a communication apparatus, where a first terminal device determines that a reserved resource of a second terminal device is within an initiated COT of the first terminal device. In this case, the first terminal device sends first COT sharing information to the second terminal device within the first COT, to indicate the second terminal device whether to share a first COT, so that the second terminal device can also perform sidelink transmission by using a resource within the initiated COT of the first terminal device.

Abstract: This application discloses a communication method and a communication apparatus. The method applied in a half-duplex terminal device in paired spectrum includes: receiving first information, wherein the first information is used to enable the terminal device to perform DMRS bundling; and determining that an actual time domain window TDW in a nominal time domain window TDW ends on a last symbol for an uplink transmission before a first event, wherein the nominal TDW is for DMRS bundling, the first event is an event that causes power consistency and phase continuity not to be maintained, and the first event comprises one or more of the following: a dropping or cancellation of an uplink transmission within the nominal TDW due to a conflict rule; or an overlapping of a gap between two consecutive uplink transmissions within the nominal TDW and a symbol for a downlink transmission.

Abstract: A communication method includes a communication apparatus that determines first information indicating that N consecutive time units are configured for sending a first message in a joint transmission manner. A receiving device that receives the first message performs joint channel estimation in the N bundled consecutive time units to obtain the first message, and when there are P unavailable time units in the N consecutive time units indicated by the first information, the communication apparatus sends the first message in the joint transmission manner in M consecutive time units different from the P unavailable time units.

Abstract: A computing system for load processing obtains a current time and a reported load amount from an access machine at the current time and determines a delayed cognitive load amount allocated to the access machine at a first time period by subtracting a first time difference from the current time. Next the computing system determines an actual load amount of the access machine at the current time by adding the reported load amount and the delayed cognitive load amount and determines whether the access machine is running at an overload condition by comparing the actual load amount of the access machine at the current time and a maximum load amount threshold for the access machine. The present application can accurately determine the load amount that the access machine has received and schedule user terminals received by the access machine to prevent overloaded operation of the access machine.
