Abstract: A method, a device, and a system for triggering a scheduling request (SR) to meet quality of service (QoS) requirements of different services in a New Radio (NR) vehicle to everything (V2X) system and to avoid or reduce unnecessary SR triggering. The method includes that a network device sends a first message to a terminal device, where the first message includes a first identifier and one or more configuration parameters corresponding to the first identifier. The first identifier is of a first logical channel, and the first logical channel is of a sidelink (SL) radio bearer. Alternatively, there is a mapping relationship between the first identifier and the first logical channel.

Abstract: A terminal receives a power saving signal sent by a network device, where the power saving signal indicates N time units, and where N is greater than 0. The terminal determines a state of the terminal in a first time period corresponding to the N time units on a first frequency domain resource and a state in a second time period corresponding to the N time units on a second frequency domain resource. The state of the terminal includes a sleep state or a wake-up state. The sleep state indicates that the terminal monitors no first signal, and the wake-up state indicates that the terminal monitors a first signal based on a configuration parameter.

Abstract: This application provides a method that includes the step of receiving, by a first device in a first time domain position, first scheduling information. The first scheduling information includes first indication information sent by a network device, wherein the first indication information is used to indicate a first interval. The method further comprises sending, by the first device, second scheduling information including second indication information to a second device in a second time domain position, wherein the second indication information is used to indicate a second interval, which is the difference between the first interval and a third interval. The second scheduling information is used by the second device to determine the target time domain position used by the second device to determine a time domain resource used to send and/or receive data.

Abstract: Embodiments provide a Polar code transmission method and apparatus. A bit sequence is encoded into a code sequence using Polar code by a network device. The bit sequence contains a control signaling and a Cyclic Redundancy Code (CRC) sequence. The code sequence is transformed into M copies such that an ith information copy of the M copies multiples by a first matrix of the power of (i−1). M is an integer and M>0. M copies of codeword was encoded by Polar code, the M copies implicitly conveys different time stamp information, which is suitable for the transmission of PBCH in 5G communication system, signaling overhead is also reduced.
