  • Patent number: 12137472
    Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

  • Patent number: 12127160
    Abstract: A communication method and apparatus are provided. The method may be applied to a terminal and a network device. In the method, the network device first sends first indication information before sending a paging message, where the first indication information is used to indicate whether at least two terminals in an RRC_IDLE state or an RRC_INACTIVE state need to receive the paging message. In this way, after each of the at least two terminals receives the first indication information, the terminal may determine, based on the first indication information, whether the terminal needs to receive the paging message. If determining that the terminal needs to receive the paging message, the terminal may detect and receive the paging message on a corresponding time-frequency resource after the network device sends the paging message.

  • Patent number: 11963139
    Abstract: Embodiments of the application provide a sidelink logical channel multiplexing method and apparatus. After determining a first sidelink logical channel (SL LCH) that meets a first preset condition in at least one SL LCH, a terminal allocates a resource to data of the first SL LCH. Then, when a remaining resource of transmission resources is more than zero, the terminal determines, according to a communication range of the first SL LCH, a second SL LCH that meets a second preset condition, and allocates a resource to data of the second SL LCH. The first SL LCH and the second SL LCH are different. In the method, such a parameter as a communication range is considered in a multiplexing process, and data of SL LCHs with same or different communication ranges is multiplexed into a same transport block.
