Abstract

The embodiment of the invention provides a scheduling request SR sending method and device. The method is applied to a media access control layer (MAC) entity at a terminal side, and comprises the following steps: when detecting that the MAC entity meets a preset pending SR sending condition, receiving a channel interception (LBT) success indication sent by a physical layer at the terminal side; and adding one to an SR counter, and sending the channel access priority parameter of the pending SR to the physical layer, so that the physical layer determines an LBT parameter according to the channel access priority parameter and executes LBT, and the physical layer sends the pending SR. The embodiments of the present invention solve the problem of how to send an SR in an unlicensed spectrum inthe prior art.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for sending a scheduling request SR. Background technique [0002] In mobile communication systems, although the use of licensed spectrum is efficient, it is expensive and the total spectrum is limited. Unlicensed spectrum is increasingly attracting the attention of operators due to its abundant available bandwidth and relatively low license fees. Become a supplementary spectrum resource for networks already deployed based on licensed spectrum to enhance network services. In Long Term Evolution (LTE), the unlicensed spectrum has been used as the secondary cell spectrum resource of LTE equipment, that is, the unlicensed spectrum is used as an auxiliary carrier in the form of carrier aggregation with the LTE licensed spectrum carrier, which is called authorization. Spectrum Assisted Access (Licensed Assisted Access, LAA). [0003] The 3GPP...
