Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.

Abstract: The application relates to allocating transmission resources in communication networks that provide low latency services. A terminal receives, from a base station time-frequency resource division information, which indicates a division of a time-frequency resource that is allowed to be used by another service. The division of the time-frequency resource includes one or more resource units in time domain and one or more resource units in frequency domain. The terminal further receives from the base station time-frequency resource indication information, which indicates that, in the time-frequency resource that is allowed to be used by the other service, at least one time domain resource unit and at least one frequency domain resource unit are occupied by the other service. The terminal communicates with the base station using the time-frequency resource except the at least one time-domain resource unit and at least one frequency-domain resource unit that are occupied by the other service.

Abstract: A resource request method and system, a device, and a network side node are provided. The method includes the following steps: A target device sends a first target device message to a relay device. When receiving the first target device message, the relay device sends a first relay device message to a network side node according to the first target device message. The network side node receives the first relay device message, and sends first grant information to the target device according to the first relay device message. The first grant information includes a data transmission resource allocated by the network side node to the target device. According to embodiments of the present disclosure, energy consumption of a sending device, that is, a target device, can be reduced while the sending device obtains a transmission resource.
