Problems solved by technology

It is easy to see that since the number of bits of resource indication signaling is the same as the number of RBs, the amount of signaling overhead required by the bitmap method is relatively large

Embodiment Construction

[0052] The core idea of ​​the present invention is: when there are less than N / 2 resource blocks in the N resource blocks that need to be indicated, an indication sequence composed of N-bit binary numbers is set, and according to the value of any specified bit in the indication sequence, Acquire resource indication signaling composed of (N-1) bit binary sequences.

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0054] Fig. 2 is a schematic diagram of the communication system resource indication system of the present invention. As shown in Fig. 2, the system includes two parts: a communication system resource indication sending device and a communication system resource indication receiving device:

[0055] Wherein, the device for sending the communication system resource indication inc...

Abstract

In the invention, when less than N / 2 resource blocks in N resource blocks needs to be indicated, the method comprises: a) setting an indication sequence composed of N bit binary numbers; b) according to the value of any appointed bit in the indication sequence, getting a resource indication signaling composed of N-1 bit binary sequence to indicate the resource block. The invention also reveals a communication system resource indication system, an apparatus for sending communication system resource indication and an apparatus for receiving the communication system resource indication. By the invention, the resource indication signaling can reduce one bit information comparing the resource indication signaling obtained from bitmap method.

Description

technical field [0001] The invention relates to communication resource allocation technology, in particular to a communication system resource indication method, system, sending device and receiving device. Background technique [0002] In the 3rd Generation Partnership Project (3GPP) Evolved Universal Terrestrial Radio Access (E-UTRA, Evolved Universal Terrestrial Radio Access) system, frequency domain scheduling is an important feature. For example, if the system transmission bandwidth is divided into resource blocks (RB, ResourceBlock) composed of multiple consecutive subcarriers, then the UE measures the channel quality of each RB and reports it to the base station through signaling, and the base station assigns the channel quality according to the scheduling algorithm RBs with good quality are allocated to UEs to implement frequency domain scheduling. In order to save the amount of signaling for channel quality reporting, the UE can only report the channel quality para...
