Embodiment 1

[0057] In this embodiment, a kind of running on figure 1 The subframe configuration method of the shown network architecture, figure 2 is a flowchart of a subframe configuration method according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0058] Step S202, determining the configuration of the second type of subframe according to the configuration of the first type of subframe and the bitmap sequence of the subframe configuration bitmap of the resource pool, wherein the second type of subframe is a reserved subframe without bitmap sequence mapping;

[0059] Step S204, performing mapping of the subframe configuration bitmap sequence of the resource pool according to the configuration of the first type of subframe and the configuration of the second type of subframe.

[0060] Through the above steps, determine the configuration of the second type of subframe according to the configuration of the first type ...

Embodiment 2

[0081] In this embodiment, a subframe configuration device is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0082] Figure 5 is a structural block diagram of a subframe configuration device according to an embodiment of the present invention, such as Figure 5 As shown, the device includes:

[0083] The determining module 50 is a determining module configured to determine the configuration of the second type of subframe according to the configuration of the first type of subframe and the bitmap sequence of the subframe configuration bitmap ...

Embodiment 3

[0099] This embodiment is an optional embodiment according to the present invention, and is used to describe the application in detail in conjunction with specific examples:

[0100] In the resource pool configuration of the Sidelink in this embodiment, the resource pool includes one or more subframes, and the subframes included in the resource pool are indicated through a subframe bitmap sequence (bitmap). According to the bitmap sequence indicated by the base station or pre-configured by the system, the bitmap sequence is mapped from the subframe position where the system subframe number SFN (System Frame Number) is #0. Usually, the corresponding subframe configures the bitmap sequence indication When the bit is "1", it means that this subframe is a subframe in the resource pool, and when it is "0", it means that this subframe is not a subframe in the resource pool. The bitmap sequence of the subframe configuration is repeatedly mapped within the range of the system subframe...

Abstract

The invention provides a subframe configuration method and device. The method comprises the steps of determining configuration of a second class of subframes according to the configuration of a firstclass of subframes and a subframe configuration bitmap sequence of a resource pool, wherein the second class of subframes are reserved subframes on which bitmap sequence mapping is not carried out; and carrying out mapping of the subframe configuration bitmap sequence of the resource pool according to the configuration of the first class of subframes and the configuration of the first class of subframes. Through application of the method and the device, the problem that in related technologies, the time delay is instable when information transmission is carried out on the subframes contained in the resource pool is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a subframe configuration method and device. Background technique [0002] In the D2D communication system in the related art, when there is business to be transmitted between user equipment (User Equipment, referred to as UE), the business data between UEs is not forwarded by the base station, but is directly transmitted by the data source UE through the air interface. transmitted to the target UE, figure 1 is a schematic diagram of the D2D communication structure in the related technology of the present invention, such as figure 1 As shown, the wireless link between D2D UEs is called a side link (Sidelink, SL for short). In general, D2D transmission not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, which can reduce system resource occupation, increase the spectrum efficiency of cellular communication systems, red...
