Multi-user burst discontinuous low-rate service transmission method and device

Abstract

Embodiments of the invention disclose a multi-user abrupt discontinuous low-rate service transmission method and a device. The method comprises the steps as follows: when determining that a current to-be-transmitted service is a multi-user abrupt discontinuous low-rate service, combining abrupt discontinuous low-rate service data of multiple users and assigning TB resources to the combined abrupt discontinuous low-rate service data; using the same MCS to assign a code word to each TB resource; carrying out spatial transmission diversity-multiplexing of the TBs after code word assigning, carrying the TBs on a data channel, and generating a control channel corresponding to the data channel; and carrying out transmission of the data channel and the control channel at an air interface. By aggregating the air-interface physical resource blocks occupied by abrupt discontinuous low-rate service, the conflict probability of the control channel is lowered, and resource fragmentation is reduced.

Description

technical field [0001] The present invention relates to a multi-user burst discontinuous low-rate service transmission technology, in particular to a multi-user burst discontinuous low-rate service transmission method and device suitable for a Long Term Evolution (LTE, Long Term Evolution) system. Background technique [0002] With the promotion of the mobile Internet, various Internet services need to realize the connection between the terminal and the Internet server through the wireless mobile network, especially after the broadband wireless mobile network beyond 4G or even 5G is popularized, the wireless mobile network will surely support more Internet business. [0003] Various Internet applications such as QQ service, WeChat service, web browsing service, various microblog interactive services, online instant chat service, website login processing, etc., have the common characteristics of discontinuous data transmission, low service rate, and burst data packets. It ma...

Problems solved by technology

[0006] When transmitting downlink burst discontinuous low-rate service data, the amount of data for each user is very small, and the number of PRBs to be allocated is not large, resulting in too many fragments in the system bandwidth, which undoubtedly reduces resource utilization and increases The complexity of resource allocation is increased, and at the same time, due to a large number of users applying for resources, the probability of limited control channels is increased
