Problems solved by technology

[0003] In the multi-stream transmission scenario, since the transmission resources of different cells need to be occupied, logical channels need to be mapped to different transmission channels and / or to different physical entities. However, according to the existing MAC layer function, only all logical Channels are mapped to the same transport channel and the same physical entity, and it is impossible to map logical channels corresponding to different services to different transport channels and / or physical entities

Abstract

The invention provides a multi-streaming transmission scheduling method and equipment. The method comprises the steps of: receiving MAC (Media Access Control) layer configuration parameters of a corresponding MAC entity, wherein when one MAC entity is provided, the MAC layer configuration parameters comprise at least two groups of mapping relationships, and the mapping relationships comprise a first mapping relationship and / or a second mapping relationship, or when at least two MAC entities are provided, the MAC layer configuration layers of each MAC entity comprise one group of mapping relationships, and the mapping relationships comprise a third mapping relationship and / or a fourth mapping relationship; and according to the MAC layer configuration parameters, executing MAC layer functions, and carrying out MAC layer data transmission. According to the multi-streaming transmission scheduling method and equipment provided by the invention, requirements of multi-streaming transmission can be met.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a scheduling method and equipment for multi-stream transmission. Background technique [0002] Exists in long-term evolution (Long Term Evolution, LTE) technology, device-to-device (Device to Device, D2D) or uplink (Uplink, UL) aggregation, UL cross-radio access technology (Radio Access Technology, RAT) multi-carrier technology Multi-stream transmission scenarios. In a multi-stream transmission scenario, the multi-stream control method may use different radio bearers (Radio Bearer, RB) to be distributed to different cells for data transmission. For example, the control plane bearer and the user plane bearer are transmitted separately in different cells, or different RBs are mapped to different cells. [0003] In the multi-stream transmission scenario, since the transmission resources of different cells need to be occupied, logical channels need to be mapped to differ...
