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 dynamic mobile network architecture is provided, with the objective of meeting greenhouse gas emission targets. The network adapts over time based on time varied traffic demand/load. This is achieved by providing two layers of base stations (BS). The top layer contains super BS that have larger coverage areas than the base stations of the second layer. Depending on traffic conditions, base stations of the second layer can be switched into a reduced power mode. Signalling procedures are provided for setting up connections between the BS of the second layer and the super BS, and for switching off and then activating previously switched off second layer BS. In some cases, the BS of the second layer has a lower power listening receiver to allow itself to be activated while the BS is otherwise powered off.

Abstract: A video service transmission method and apparatus in the field of communications technologies are provided, where data in a video data frame can be split into at least two substreams based on a mapping relationship between data importance and a substream. The data of the at least two substreams may then be mapped, based on port numbers corresponding to the at least two substreams, to bearers corresponding to the at least two substreams, for transmission. Because a network can use different processing methods for data on different bearers, reliable transmission of video data frames of high importance can be ensured with priority by using the video service transmission method and apparatus, so as to improve service experience of video users in a scenario of constrained transmission resources.

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.
