Problems solved by technology

[0010] First of all, due to the transmission of TCP / IP, the real-time performance is relatively strong, but the current implementation mechanism is to report the SR at the SR time point first, and then report the BSR on the newly allocated resources. The overall cycle is relatively long, resulting in time-consuming If the extension is too large, it will affect the overall perception
[0011] Secondly, SR resources belong to PUCCH, and PUCCH belongs to the edge of uplink resources, which may be more likely to be interfered. Depending on the difference between terminals, false detection or missed detection may occur, resulting in too many invalid scheduling of some terminals, or too little effective scheduling, resulting in The delay is too large, affecting the overall perception

Embodiment Construction

[0073] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0074] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for scheduling uplink resources in the present invention, which may include the following steps:

[0075] Step 101, when receiving an acknowledgment signal for downlink data fed back by the terminal, start a scheduling timer;

[0076] Step 102, within the timing range of the scheduling timer, periodically perform uplink resource pre-scheduling according to a preset interval time.

[0077] In the embodiment of the present invention, when the receiving terminal feeds back ACK for the downlink HARQ process of the downlink data, the scheduling timer is started, and within the timing range of the scheduling timer, the uplink resource reservati...

Abstract

The embodiment of the invention provides an uplink resource scheduling method and device, wherein the method comprises the steps of: when a confirmation signal fed back by a terminal for downlink datais received, starting a scheduling timer; and, in the timing range of the scheduling timer, periodically performing uplink resource pre-scheduling according to the pre-set interval time. According tothe embodiment of the invention, application of uplink resources can be carried out without SR resources; feedback information of the terminal can be scheduled accurately and effectively; therefore,the downlink data feedback delay is reduced; the TCP handshaking delay is reduced; and the user perception is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for scheduling uplink resources and a device for scheduling uplink resources. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the signaling, data and other downlink data sent by the LTE system to the UE (user terminal) are generally based on TCP (Transmission Control Protocol, transmission control protocol) / IP (Internet Protocol, Internet Protocol) data packets, after sending the downlink data to the UE, the UE will feed back relevant handshake information to the base station through the uplink data. [0003] In the prior art, the relevant implementation of the LTE system for sending UE downlink data is as follows: [0004] (1) After receiving downlink signaling or data, the UE generates uplink related feedback data, triggers an SR (Scheduling Request, uplink scheduling request), and applies for uplink resourc...
