Abstract

The invention discloses a method for distributing radio resources, which comprises the steps: a dispatching party selects an expanding mode for expanding basic resource blocks or a splitting mode for splitting the basic resource blocks according to predetermined factors; the dispatching party splits the basic resource blocks to obtain splitting resource blocks or expands the basic resource blocks to obtain expanding resource blocks according to the selected splitting mode or the selected expanding mode; the dispatching party dispatches the expanding resource blocks or the splitting resource blocks to a dispatched party and indicates the selected splitting mode or the selected expanding mode to the dispatched party in a predetermined mode; and the dispatching party uses the basic resource blocks, the expanding resource blocks and the splitting resource blocks or the combination of the blocks to carry out resource distributing description and transmits resource distributing description information to the dispatched party. The invention can increase the dispatching efficiency of the radio resources and ensure different service types of QoS and the spectrum efficiency of a prospective wireless communication system.

Description

technical field

[0001] The present invention relates to the communication field, and in particular, relates to a radio resource allocation method. Background technique

[0002] In a wireless communication system, a base station is a device that provides services to terminals. The base station communicates with the terminal through uplink and downlink. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. In a wireless communication system that uses a base station to implement wireless resource scheduling control, the scheduling and allocation of system wireless resources is completed by the base station. For example, the base station provides resource allocation information when the base station perform...

Embodiment Construction

[0032] According to the characteristics of the frame structure and business of the future wireless communication system, the present invention proposes a method for indicating resource allocation units, and the specific contents include:

[0033] One or more basic resource blocks are defined in the wireless communication system, and the basic resource block refers to: obtained by expanding and splitting only in the time domain, or only in the frequency domain, or in the time-frequency domain or the air domain at the same time Extended resource blocks, or split resource blocks. Basic resource blocks, extended resource blocks and split resource blocks constitute a set of radio resource allocation units in a wireless communication system. Extension and splitting do not affect each other. The wireless communication system can only support extended resource blocks and basic resource blocks, or split resource blocks and basic resource blocks, or basic resource blocks, extended resou...
