A resource allocation method for coexistence of multiple line topological industrial wireless networks is provided. It pertains to the coexistence problem of multiple TDMA-based line topological industrial wireless networks, including three parts: lower bound analysis of scheduling delay, allocation algorithm of inter-network resources and allocation algorithm of intra-network resources. The method uses overall scheduling delay and resource utilization ratio as measurement indexes when analyzing the lower bound of delay and designing resource allocation algorithms, and selects a best node combination in each time slot to occupy as many channel resources as possible to improve the resource utilization ratio and reduce the overall scheduling delay.

This application provides a resource configuration method and a communication apparatus. In the technical solutions of this application, a donor node may configure different DU resource configurations for an IAB node and two parent nodes of the IAB, so that the IAB node can determine MT resources for different parent nodes based on the different DU resource configurations, to implement resource configuration of the IAB node in a dual connectivity scenario.

The disclosure described herein configures a base station and client devices for communication using dynamic spectrum access within a frequency spectrum that includes selecting, from a list of available channels, a set of channels as active channels. The active channels include uplink channels and downlink channels, and the active channels are distributed among a plurality of base station radios of a base station. A different channel is assigned to different base station radios. At least one uplink channel and at least one downlink channel are assigned to a plurality of client devices based on locations the client devices, wherein at least some client devices have active channels in common. The client devices having the active channels in common are also grouped on shared channels and time slots assigned to the client devices in the group, thereby allowing narrowband communication over the channels by the client devices.

A communication method and an apparatus are provided. The method includes: A common application programming interface framework core function (CCF) network element first sends reference information of an application to a first network element. Therefore, the first network element determines network slice information corresponding to the application; and then the first network element sends the determined network slice information to the CCF network element. In this way, the CCF network element may determine the network slice information corresponding to the application, so that when an API invoker network element searches for an API, the CCF network element can accurately find, based on an API inquiry parameter, the API from a network slice corresponding to the network slice information.

This disclosure describes techniques for optimizing the allocation of physical resource blocks (PRBs) for user equipment (UE), such as a Narrow-Band Internet of Things (NB-IoT) device, within a Long-Term Evolution (LTE) spectrum. More specifically, a resource allocation controller that is configured to select one of at least two resource allocation algorithms that allocate physical resources within an LTE spectrum, based on an identity of the UE and an analysis of real-time or near real-time physical resource utilization and control utilization within the LTE spectrum. In one example, the resource allocation controller may analyze the physical resource utilization and control utilization within a subframe of an LTE spectrum to determine whether to allocate an exact or near-exact number of PRBs for data communications of a UE (i.e. NB-IoT device), or whether to allocate a PRB group (at least four PRBs) for data communications of the UE.

A method of controlling service transmission, a terminal and a network device are provided, the method is performed by a first terminal, including: obtaining an indication signaling, where the indication signaling includes: first indication information of a resource position occupied by a high-priority service transmission of a second terminal in a reference resource domain, and second indication information indicating whether there exists a resource conflict between a service transmission of the first terminal and the high-priority service transmission; when there exists a resource conflict between the service transmission of the first terminal and the high-priority service transmission, stopping a service transmission on a target resource position where the resource conflict occurs according to the first indication information.

An indicator in a master AP from among a plurality of APs obtains communication quality of communication with an AP which is a communication partner. In the case where the obtained communication quality is less than a threshold, the indicator causes the plurality of APs including the master AP to perform cooperative operation to transmit data. In the case where the obtained communication quality is not less than the threshold, the indicator causes the plurality of APs including the master AP to stop the cooperative operation.
