Example Embodiment

[0211] Example one

[0212] This embodiment mainly describes the division methods of different priorities. Among them, the different priorities are divided as follows: One is to divide different priority levels according to different types of services. The other is to classify different priority levels according to signals and / or channels and / or logical channels. In addition, according to different priorities, the corresponding LBT mechanism used when the LBT process is executed and / or the LBT parameter set under the used LBT mechanism can be learned.

[0213] Further, according to different priority classification methods, different priority levels correspond to different LBT mechanisms and / or parameter sets, or correspond to different element values ​​in parameter sets under a specific LBT mechanism. Wherein, for different priority levels based on signals and / or channels and / or logical channels, a certain priority level may include at least one of the following: signal, channel...

Example Embodiment

[0229] Example two

[0230] This embodiment focuses on explaining the priority levels corresponding to different channels and / or signals and / or logical channels, and uses different parameter sets corresponding to the LBT Cat2 mechanism when channel contention access is used. Among them: Fig. 3(a) is a schematic diagram of LAA terminal performing LBT in self-scheduling mode provided by the present invention; Fig. 3(b) is a schematic diagram of LAA terminal performing LBT under cross-carrier scheduling mode provided by the present invention.

[0231] Specifically in this embodiment, different priority levels correspond to different parameter sets in the LBT Cat2 mechanism. Here, the elements in the parameter set are the CCA detection duration. Different parameter sets refer to different CCA detection durations, for example, the CCA detection durations are 34us, 25us, 20us, 18us, 16us, 9us, 4us. The higher the priority level, the shorter the CCA detection duration in the correspondi...

[0260] Example three

[0261] This embodiment focuses on explaining the priority levels corresponding to different service types, and uses different parameter sets corresponding to the LBT Cat2 mechanism during channel contention access.

[0262] Specifically in this embodiment, different priority levels correspond to different parameter sets in the LBT Cat2 mechanism. Here, the elements in the parameter set are the CCA detection duration. Different parameter sets refer to different CCA detection durations, for example, the CCA detection durations are 34us, 25us, 20us, 18us, 16us, 9us, 4us. The higher the priority level, the shorter the CCA detection duration in the corresponding LBT Cat2 mechanism. For illustration, see Table 7 below:

[0264] Table 7

[0265] In Table 7, the priority levels in this embodiment are priority levels corresponding to different service types. Priority level 1 is the highest priority, and the p...

Abstract

The invention discloses an LAA equipment competition access parameter configuration method and device. The method comprises the steps that different LBT mechanisms or LBT mechanism parameter sets corresponding to different priority levels are determined according to different priority levels; competition access operation of an unauthorized carrier is performed by using different LBT mechanisms or LBT mechanism parameter sets corresponding to different priority levels; and when the right to use the unauthorized carrier is successfully acquired according to the LBT mechanisms or LBT mechanism parameter sets, data transmission is performed by using the unauthorized carrier.

Description

technical field [0001] The present invention relates to a licensed-assisted access (LLA, Licensed-Assisted Access) technology in wireless communication, in particular to a method and device for configuring LAA equipment competition access parameters. Background technique [0002] With the rapid growth of data services, the data transmission pressure on licensed spectrum carriers is also increasing. Therefore, using unlicensed spectrum carriers to share the data traffic in licensed carriers has become a follow-up Long Term Evolution (LTE ) is an important evolutionary direction of development. [0003] The characteristics of unlicensed spectrum are: unlicensed spectrum does not need to be purchased, spectrum resources are zero-cost, and have the characteristics of free / low cost; individuals and enterprises can participate in deployment, equipment manufacturers can deploy equipment at will, and have low access requirements. The feature of low cost; the 5GHz, 2.4GHz and other ...
