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, LongTermEvolution) 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 may ...

Embodiment Construction

[0068] The embodiment of the present invention follows the general rule of business model scheduling, and for the downlink burst discontinuous low-rate business, each user only needs to transmit a single codeword (one MAC TB block). Specifically, the embodiment of the present invention improves the transmission diversity gain by extending the SFBC and FSTD, and realizes the transmission diversity transmission of multi-user data.

[0069] figure 2 It is a flowchart of a multi-user burst discontinuous low-rate service transmission method according to Embodiment 1 of the present invention, such as figure 2 As shown, the multi-user burst discontinuous low-rate service transmission method in the embodiment of the present invention includes the following steps:

[0070] Step 201, when it is determined that the current service to be transmitted is a multi-user burst discontinuous low-rate service, the burst discontinuous low-rate service data of multiple users are combined togethe...
