Embodiment 1

[0066] Assume that there are two uplink subframes in one radio frame, and the system sets two TTI configurations, namely TTI is one subframe and two subframes. Multiple tiles forming an LDRU under different TTI configurations are physically discretely distributed according to sub-channelization and corresponding resource block structures, such as figure 2 shown. Wherein, the LDRU whose TTI is one subframe is composed of three tiles; the LDRU whose TTI is two subframes is composed of two tiles, and each rectangle filled with oblique lines represents a tile. figure 2 The horizontal direction is the subframe, each subframe has 6 symbols, and the vertical direction is the subcarrier. figure 2 For illustrative purposes only, three tiles when the TTI is one subframe, and two tiles when the TTI is two subframes, does not mean continuous or equal intervals.

Embodiment 2

[0071] Assume that there are two uplink subframes in one radio frame, and the system sets two TTI configurations, namely TTI is one subframe and two subframes. Multiple tiles forming an LDRU under different TTI configurations are physically discretely distributed according to sub-channelization and corresponding resource block structures, such as Figure 4 shown. Among them, the LDRU whose TTI is one subframe is composed of three tiles; the LDRU whose TTI is two subframes is composed of four tiles, and each rectangle filled with oblique lines represents a tile. Figure 4 The horizontal direction is the subframe, each subframe has 6 symbols, and the vertical direction is the subcarrier. Figure 4 For illustrative purposes only, three tiles when the TTI is one subframe, and four tiles when the TTI is two subframes, does not mean continuous or equal intervals.

Embodiment 3

[0076] Assuming that the number of uplink subframes in one radio frame is three, the system sets two TTI configurations, namely TTI is one subframe and three subframes. Multiple tiles forming an LDRU under different TTI configurations are physically discretely distributed according to sub-channelization and corresponding resource block structures, such as Figure 6 shown. Wherein, the LDRU whose TTI is one subframe is composed of three tiles; the LDRU whose TTI is three subframes is composed of three tiles, and each rectangle filled with oblique lines represents a tile. Figure 6 The horizontal direction is the subframe, each subframe has 6 symbols, and the vertical direction is the subcarrier. Figure 6 For illustrative purposes only, three tiles when the TTI is one subframe and three tiles when the TTI is three subframes do not mean continuous or equal intervals.

Abstract

The invention discloses a method for sub-channelizing and mapping wireless resources, which comprises the steps of carrying out replacement and rearrangement on the resources in a conventionally distributed resource group in each uplink sub-frame by taking the basic unit (tile) as the unit; dividing the conventionally distributed resources in each uplink sub-frame into distributed resource sub-groups corresponding to all TTI allocations according to allocated transmission time interval (TTI) allocation combined information; and replacing and / or mapping an LDRU onto the tile in the frequency band of the corresponding distributed resource sub-group in a frequency hopping way according to the logic distributed resource block (LDRU) structure under the corresponding TTI allocation of the distributed resource sub-group in each distributed resource sub-group. The adoption of the method can realize the sub-channelizing and the mapping of the wireless resources with the different TTI allocation combinations, thereby meeting a variety of user business performance demands, fully and high-efficiently utilizing the resources and improving the frequency spectrum effectiveness of a system.

Description

technical field [0001] The present invention relates to a wireless resource mapping technology in Orthogonal Frequency Division Multiplexing (OFDM), in particular to a method for channelizing and mapping wireless resource sub-channels on different transmission time intervals (TTI, Transmission Time Interval). Background technique [0002] With the continuous development of broadband wireless communication technology, next-generation mobile communication systems such as Worldwide Interoperability for Microwave Access (WiMAX), Ultra Mobile Broadband (UMB) and 3GPP Long Term Evolution (LTE) all use OFDM multiple access methods. Users achieve the purpose of multiple access by occupying a certain amount of orthogonal sub-carrier resources. [0003] In an OFDM system, it is divided into multiple OFDM symbols in the time domain, and multiple sub-channels in the frequency domain, and each sub-channel is a set of sub-carriers. Subchannelization (Subchannelization) allows user statio...
