Problems solved by technology

[0008] Use the BS broadcast method to assign all MS resources. The broadcast content includes all assignment information. In order to consider the users with the worst channel environment, the broadcast message needs to use a low-order modulation and coding method, which makes the overhead too large.

Embodiment Construction

[0029] The present invention provides a method, system and corresponding device for assigning resources, assigning resources to MSs through a bitmap (Bitmap), reducing the amount of information sent in broadcast mode, and reducing the overhead caused by broadcast mode assignment Too large, and interference to neighboring cells.

[0030] In the embodiment of the resource allocation method provided by the present invention, the BS uses Bitmap to record the resource allocation information and broadcasts it to the MS. There are many kinds of resources available for allocation. In this embodiment, time-frequency resources are taken as an example for description.

[0031] Each Bitmap contains a number of bits (Bit) used to assign time-frequency resources. For ease of description, the Bits used to assign time-frequency resources in this embodiment can be called resource bits, and each Bit corresponds to the number of reservations Time-frequency resource unit, the present invention o...

Abstract

The invention discloses a method for assigning resources, which comprises the steps of: forming a bit map by utilizing resource bits used for assigning resources, leading one resource bit to correspond to preset amount of resource units; indicating the number of corresponding blocks with assigned resources and indicating the situation of each block assigned to a resource unit by utilizing the resource bits; and transmitting the bit map to a terminal so as to lead the terminal to know the number of blocks with assigned resources and number of each block assigned to the resource unit by the bit map. The invention also discloses a system, a base station and a terminal corresponding to the assigned resources. By utilizing the invention, the size of a broadcast message is reduced, the cost of communication is reduced and the interference to a neighborhood is reduced, when the resources are assigned.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for assigning resources. Background technique [0002] Generally, a wireless communication system includes: a base station (BS, Base Station) and a terminal (MS, MobileStation). [0003] The BS and MS communicate through the air link. There is a BS-controlled communication method, that is, the BS assigns certain resources to the MS, and the MS analyzes the corresponding downlink data or sends the corresponding uplink data according to the resources assigned by the BS. data. Here, the downlink refers to the direction that the BS sends to the MS, and the uplink refers to the direction that the MS sends to the BS. [0004] In an Orthogonal Frequency Division Multiple Access (OFDMA, Orthogonal Frequency Division Multiplex Access) system, an Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplex) technolog...
