Problems solved by technology

[0009] Although the above technical solution can realize the joint indication of resource allocation for multiple users, the public information also includes UE-ID, which causes more signaling overhead; and the length of the public information changes with the number of scheduled users. If Allocating the length of public information according to the maximum possible number of scheduling users will cause waste of resources when the number of scheduling users is small. If the length of public information is allocated according to the actual signaling amount, in order to ensure that users can demodulate the public information , additional information needs to be transmitted to indicate the length of the public information, or multiple blind checks are required to determine the length of the public information, which will increase the complexity of the user's parsing of the public information

Embodiment Construction

[0023] see image 3 , is a flow chart of a preferred embodiment of the resource allocation indication method provided by the present invention. In this embodiment, all resource allocation indication signaling is sent to all users as public information. The resource allocation indication method involved in this embodiment specifically includes the following steps:

[0024] Step 101: Allocate PRBs to scheduling users, including centralized transmission users and decentralized transmission users, that is, divide the system broadband into multiple PRBs, and allocate a certain number of PRBs to each scheduling user, among which L-PRBs are allocated to centralized transmission users and distributed transmission users Users allocate D-PRBs.

[0025] Step 102: Generate public information through joint coding according to the allocation of PRBs for centralized transmission users and distributed transmission users. The public information includes all resource allocation indication sig...

Abstract

The present invention provides a resource distribution direction method and its system, for indicating the distributing instance of physical resource block, the method includes: to generate whole or part resource distributing indicating signalling of unite encoding based on the distributing instance of physical resource block, which generates independent control signalling together with resource distributing corresponding information as well as control information; adding user identifier into the control signalling encoded independently; transmitting the whole or part resource distributing signalling as public information to all users, and the control signalling to the corresponding users; users confirm distributed physical resource block position according to public information as well as control signalling. The present invention reduces the signalling amount of transmitted public information and the complexity of analyzing public information by users.

Description

technical field [0001] The present invention relates to mobile communication physical layer technology, in particular to a technology for indicating allocation of physical resource blocks. Background technique [0002] At present, the Evolved Universal Terrestrial Radio Access (E-UTRA, Evolved Universal Terrestrial Radio Access) system proposed by the Third Generation Partnership Project (3GPP, Third Generation Partnership Project) uses Orthogonal Frequency Division Multiplexing (OFDM) in downlink transmission. , Orthogonal Frequency Division multiplexing) technology. OFDM is a multi-carrier communication technology that realizes multi-user multiplexing by allocating different physical resources for different users. The downlink transmission of the E-UTRA system can be further divided into localized transmission (Localized Transmission) and distributed transmission (Distributed Transmission). The transmission bandwidth of the E-UTRA system is evenly divided into a pluralit...
