Embodiment Construction

[0051] The present invention will be further described below by taking the TD-SCDMA system as an example.

[0052] For the convenience of the following description, the following definitions are first made:

[0053] FPACHi: FPACH channel number i;

[0054] L i : The length of the RACH message related to FPACHi in the subframe;

[0055] L iE : The length of the E-RUCCH message related to FPACHi in the subframe;

[0056] N RACHi : the number of PRACHs associated with the i-th FPACH;

[0057] N E-RUCCHi : the number of E-RUCCHs associated with the i-th FPACH;

[0058] no RACHi : The number of the PRACH associated with the i-th FPACH, ranging from 0 to N RACHi-1 ;

[0059] no E-RUCCHi : The number of the E-RUCCH associated with the i-th FPACH, ranging from 0 to N E-RUCCHi -1;

[0060] WT: the maximum number of subframes used to wait for the network to confirm a sending signature;

[0061] SFN': Subframe number to confirm arrival;

[0062] SFN: system subframe number...

Abstract

The invention provides a reinforced random access control channel resource allocation method. Information length of E-RUCCH is adjusted according to the physical resources of the PRACH channel; physical resource sharing relation of E-RUCCH and PRACH and transmitting time of FPACHI are defined according to the information length of E-RUCCH; accordingly, PRACH physical resource is made full use of, and wasting of resources is reduced to some extent. By adopting the invention, E-RUCCH information content can be read out in a short time when the information length of E-RUCCH is smaller than the information length of PRACH by defining the fixed E-RUCCH information length, and the access time lag is reduced by comparing the invention with the prior art. In addition, the invention also provides a reinforced random access control channel device to be more applicable for the reinforced random access course of TD-SCDMA system.

Description

technical field [0001] The present invention relates to the communication field, in particular to an enhanced random access control channel resource allocation method and structure. Background technique [0002] High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) is a technology developed for the transmission of high-speed uplink data in third-generation mobile communications, and can be used to provide a complete 2000 International Mobile Communications Standard (IMT2000, International Mobile Telecommunications 2000 ) Multimedia, video streaming and other IP services required. [0003] HSUPA is an enhanced technology for user equipment (UE, User Equipment) to send data to the system. Because whether the UE can send data is controlled by the system, the UE needs to send an access request to the system before sending data to the system. When the system (Node B) determines that the UE can send data, it will allocate available physical resources to the...
