Problems solved by technology

[0007] The technical problem to be solved by the present invention is: in the prior art, when the network side of the multi-carrier system allocates resources to the user terminal, the compatibility with various types of terminals is not fully considered, and there is a phenomenon that the user terminal does not support the wireless resource configuration scheme , which causes the problem of access failure

Embodiment Construction

[0028] In the process of wireless resource allocation, the network side not only considers whether the system has enough resources to allocate to the terminal, but also considers the compatibility of the terminal, provides a channel configuration that matches the terminal capability, and notifies the terminal to execute through the channel configuration command. Therefore, the problem of terminal access failure caused by radio resource configuration without knowing the support capability of the user terminal is avoided.

[0029] For the HSDPA / HSUPA / HSPA+ system, in addition to allocating enhanced shared channels such as HS-DSCH and E-DCH to support its business data and some signaling data, the resource allocation process also needs to allocate a series of control channels (such as uplink / downlink accompanying channels, HS-SCCH, HS-SICH, E-AGCH and E-HICH), if there are not enough resources to allocate control channels, admission failure and channel allocation failure will also...

Abstract

The invention provides a resource allocation method for multicarrier system, which comprises: network side carries out an admission control judge to users according to the resource condition in cell, and allocates wireless resources according to the reported access capacity for the successive admission user and informs the terminal to carry out chain establishment operation through channel configuration command. The technical scheme in the invention fully considers the compatibility to all types of terminals, solves the problem of the reduction of network access ratio and capacity exists in current technology caused by that user terminal does not support the wireless resource allocation scheme when the network side allocates resources to user terminals. The execution of the invention can reduce lost call rate efficiently, and improves the network quality and the revenue of operators.

Description

technical field [0001] The present invention relates to the technical field of resource allocation in mobile communication systems, more specifically, to a resource allocation method and device applicable to multi-carrier systems. Background technique [0002] With the development of mobile communication technology, in order to increase the service peak rate and system capacity, high-speed packet access technology (HSPA, including HSDPA, HSUPA and HSPA+) has been introduced successively. The HSPA system adopts key technologies such as high-order modulation (such as 16QAM and 64QAM), AMC, HARQ, Node B fast scheduling and even MIMO, which greatly improves the service peak rate and the overall throughput of the cell. These key technologies focus on improving the performance of some enhanced shared channels (such as HS-DSCH and E-DCH), while cooperating with a series of control channels (such as uplink / downlink accompanying channels, HS-SCCH, HS-SICH, E-AGCH and E-AGCH) -HICH) ...
