Abstract

An encoding method and apparatus for downlink packet domain data service are provided by the embodiments of this invention. The method includes the following: when data to be encoded received at one of two downlink encoding time slots occupied by one integrated uplink state flag (USF) is correct, and the data to be encoded is not received, or is received but is incorrect, at the other downlink encoding time slot, the USF of the correct data to be encoded is obtained; the USF of said correct data to be encoded is used to pre-encode the USF of the data to be encoded at the other downlink encoding time. The method in the embodiment of this invention improves the uplink performance of the packet domain data service and enhances product competitiveness.

Description

technical field [0001] The present invention relates to the communication field, in particular to a downlink packet domain data service coding method and device. Background technique [0002] With the wide application of packet domain data services, the performance of packet services has attracted more and more attention. In packet data services, the uplink data sent by the mobile terminal to the base station is scheduled by the downlink data sent by the base station. Among them, USF (Uplink State Flag) scheduling is most frequently used, that is, the mobile terminal determines whether to send data in the next uplink block according to the USF sent by the base station in advance. [0003] In the existing technology, such as figure 1 As shown, when the base station sends packet data, it needs to encode the packet data. The downlink data is divided into three parts: USF, Head segment data, and Data segment data. When the base station encodes the downlink data, it needs to enc...
