An identification and use method for receiving window parameter of resorting entity

Abstract

The utility model discloses a determining and applying method for reordering entity receiving window parameters, which is applied to multi-carrier HSDPA systems. The utility model is characterized in that: the enumeration value of the reordering entity receiving window parameters can be determined according to TSN lengths configurable according to the prior norms, thus the enumeration value of the receiving window parameters is correlated with the TSN lengths but not with the number of carriers. The method amends the prior norms and thereby ensures the consistency of configuration logics.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for determining and using a receiving window parameter of a reordering entity in a multi-carrier HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) system. Background technique [0002] At the CCSA (China Communications Standards Association) meeting in August 2005, the TD-SCDMA (Time Division Synchronous Code Division Multiple Access System) multi-carrier HSDPA industry standard (referred to as the industry standard) was approved. The project is marked by N frequency points Based on 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) single-carrier HSDPA technology, multi-carrier features are introduced to better meet the needs of operators for high-speed packet data services. The basic principle of formulating the TD-SCDMA multi-carrier HSDPA specification is: the air interface must be com...

Problems solved by technology

However, with the current standard configuration method, in the case of 3 carriers, the window length that can be selected is at least 12, and the receiving window parameters only have 3 configurable quantities: 4, 6, 8, and the corresponding actual values ​​are 12 respectively. , 18, 24, reducing the configurable space;

[0010] 2) When the high-level thinks that TSN should be represented by 9 bits, the maximum receiving window can be 256, but in the current line standard, even if 6 carriers are used, the maximum receiving window can only be 192, resulting in a waste of serial number space

[0011] However, in view of the defect that the TSN length is configurable in the above-mentioned multi-carrier HSDPA industry standard, but the value of the reordering receiving window is only related to the number of carriers, there is no effective means in the current specification to solve the above problem
