Method and apparatus for packet processing, information interactive method and frame constitution apparatus

Abstract

The invention discloses a subgroup processing method and a device, an information alternating method and a frame constructing device. The information alternating method includes the steps that a base station alternates information with a terminal by a frame, the frame includes uplink operation group information, downlink operation group information, an uplink group resource allocation table, a downlink group resource allocation table, and a plurality of gap resource subgroups which are allocated according to the preset attribute and are distributed along the whole frequency domain. Using the embodiment of the invention can avoid the movements of the sub-channels caused by link adaptation among the gap resource subgroups, can overcome the defects that the broadcast information amount increases, the gap resource occupied by the resource allocation indication information increases, and the throughput of the effective data decreases due to the movements of sub-channels among the gap resource subgroups, and can fully ensure the advantageous effect that the two-class broadcast can produce.

Description

technical field [0001] The invention relates to the field of wireless mobile communication, in particular to a method for grouping air interface resources, a grouping processing device, an information interaction method and a frame construction device. Background technique [0002] With the popularity of mobile terminals and the enrichment of data services, the number and frequency of data services used by users using mobile terminals has increased rapidly, which has sharply increased the demand for communication bandwidth. Therefore, it is necessary to make reasonable and effective use of frequency resources in the communication bandwidth, and at the same time overcome multipath fading in the wireless channel and reduce interference to make full use of the communication bandwidth resources. [0003] Orthogonal Frequency Division Multiplexing (OFDM) is an efficient parallel multi-carrier transmission technology, which divides resources in the frequency domain into multiple o...

Problems solved by technology

However, for some data services that have a longer duration and a relatively constant rate compared to the use of each frame resource of the air interface, the air interface resources will remain unchanged for a long time, and the duration of the frame will be longer

However, the base station re-allocates the time-frequency resource block to the data service for each frame and notifies the user terminal of the resources allocated for the data service through a broadcast message, which increases unnecessary operations and information transmission, and reduces the effective data throughput of the base station. traffic, increase the network burden, and reduce the effective utilization of air interface resources
