Embodiment Construction

[0046] A preferred embodiment of the present invention will be further described in detail below with reference to FIG. 3 and FIG. 4 . According to these drawings, those skilled in the art can easily implement these modules.

[0047] First refer to FIG. 3 , which is a flowchart of resource scheduling for an uplink interleaved multiple access system according to a preferred embodiment of the present invention.

[0048] Step 1: All terminals in the cell send a pilot signal 31 for CQI measurement and spatial orthogonality measurement and a scheduling request 32 to the base station;

[0049] Step 2: The base station performs CQI measurement and spatial orthogonality measurement 33 of all terminals;

[0050] Step 3: According to the CQI measurement result of the terminal and the scheduling request, the base station first tries to arrange all the terminals in independent time / frequency resource blocks; (that is, without using interleaved multiple access), so as to ensure complete or...

Abstract

A resource scheduling method for an uplink interleaver-division multiple-access system includes: all terminals in a cell transmit frequency-guiding signals and scheduling requests for channel quality measurement to a base station; the base station allows all the terminals to measure frequency domain channel quality thereof; the base station selects terminals that are going to share the same frequency resource in an interleaver-division multiple-access mode from the all terminals and couples the selected terminals; the base station transmits resource distribution information, with which the terminals can transmit data, guide frequency and control channel, to the coupled terminals according to the determined coupling decision; the terminals employ the resource distributed from the base station to transmit guiding frequency and uplink control channel for data demodulation; and the terminals employ the resource distributed from the base station to transmit uplink data. The resource scheduling method for uplink interleaver-division multiple-access system provided in the invention makes a system perform optimized resource distribution according to characteristics of interleaver-division multiple-access, thereby realizing maximization of an uplink system capacity.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource scheduling method for an uplink interleaving multiple access system. Background technique [0002] The demand for system capacity in wireless communication systems continues to increase, requiring continuous adoption of new multiplexing and multiple access technologies. At present, orthogonal multiple access technologies such as Orthogonal Frequency Division Multiplex (Orthogonal Frequency Division Multiplex hereinafter referred to as OFDM) and spatial multiplexing technologies such as (Multiple Input Multiple Output hereinafter referred to as MIMO) are mainly used to increase the capacity of the wireless communication system. On this basis, people are considering stacking and adopting other non-orthogonal multiple access technologies to achieve further capacity improvement. [0003] Theoretically speaking, the non-orthogonal multiple access met...
