Problems solved by technology

The biggest advantage of the bitmap-based signaling representation method is that it can support completely flexible resource scheduling, but this representation method needs to establish a corresponding bitmap for each user. There is a strong correlation, so the overhead waste is serious

Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] refer to figure 1 , illustrating a method for allocating system resources according to an embodiment of the present invention. Such as figure 1 As shown, the system resource allocation method includes the following steps:

[0018] S102. Divide all available subcarriers into several resource blocks, and assign a logic number to each resource block RB according to a certain rule. Among them, each resource block contains several OFDM symbols, and several subcarriers in each OFDM symbol belong to the resource block; each resource block contains the same number of OFDM symbols, and each resource block contains the same number of OFDM symbols. The number of subcarriers is also the same, and the subcarriers belonging to the same OFDM symbol in the same RB can be physically continuous or physically discontinuous; the subcarriers...

Abstract

The invention discloses a system resources allocating method, including the following steps: S102, dividing all available son carriers into a plurality of resource blocks; S104, dividing the plurality of resource block into a plurality of resource groups; and S106, allocating the plurality of resource components to at least a user. By the invention, the resource allocating and representing method becomes comparatively simple and spending can be decreased.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for allocating system resources. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM for short) technology is one of the main candidate solutions for future wireless communication technologies. OFDM technology divides a given channel into many orthogonal subcarriers in the frequency domain, modulates signals on each subcarrier separately, and performs parallel transmission on each subcarrier. In this way, although the frequency response curve of the wireless channel is non-flat and has frequency selectivity, each sub-carrier is relatively flat, and a narrow-band transmission is performed on each sub-carrier, and the signal bandwidth is smaller than the channel bandwidth, so the signal waveform can be greatly eliminated. Interference between. Since each sub-carrier is orthogonal to each other in the OFDM system, and their spec...
