Embodiment Construction

[0184]In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0185] To transmit new uplink data, the SR is used to request uplink shared channel (UL-SCH, Uplink Shared Channel) resources from the base station.

[0186] see figure 1 , the present invention proposes a method for transmitting SR, including:

[0187] Step 100, the terminal obtains the first transmission parameter of the SR.

[0188] In this step, the first transmission parameter of the SR includes at least an offset, a scheduling period and / or a repeated transmission interval.

[0189] Wherein, the first transmission parameter may also include the number ...

Abstract

The invention discloses a method and a device for transmitting a scheduling request (SR). The method comprises the following steps: a terminal acquires first transmission parameters of an SR, wherein the first transmission parameters at least include offset, scheduling cycle and / or repeated transmission interval; and the terminal determines the time interval in which the SR is to be sent according to the first transmission parameters of the SR, and repeatedly sends the SR in the determined time interval. Through the scheme of the invention, by repeatedly sending the SR in the time interval determined according to the first transmission parameters of the SR, the coverage of the SR is enhanced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for transmitting a Scheduling Request (SR, SchedulingRequest). Background technique [0002] Machine Type Communication (MTC, Machine Type Communication) or Machine to Machine (M2M, Machine to Machine) User Equipment (UE, User Equipment) is the main application form of the Internet of Things at this stage. Low power consumption / low cost is an important guarantee for its scalable application. Currently, the M2M devices deployed in the market are mainly based on the Global System of Mobile Communication (GSM, Global System of Mobile Communication) system. In recent years, due to the higher spectral efficiency of the Long Term Evolution (LTE, Long Term Evolution) system, and more and more mobile operators have determined that LTE is the evolution direction of the future broadband wireless communication system, the LTE-based M2M multi-category data ...
