Problems solved by technology

[0007] Since the transmitting device 110 may not prepare a set of sub-packets that are most suitable for the receiving device 120 it serves, it may cause a lot of delay and waste of resources for both the transmitting device 110 and any receiving device 120
Furthermore, since the transmitting device 110 may use a larger number of packets or less modulation and coding efficient subpackets than some or more of the receiving devices 120 within its range would require, successful The receiving device 120 that continuously receives the transmitted data may waste unnecessary resources to receive and decode a large amount of data

Embodiment Construction

[0024] figure 2 A schematic diagram of an exemplary wireless communication system 200 is shown. figure 2 The exemplary wireless communication system 200 shown in FIG. 2 may comply with, for example, the IEEE 802.16 series of standards. More specifically, figure 2 The basic frame structure of IEEE 802.16m is shown. exist figure 2 In the shown basic frame structure, a superframe (superframe) includes four frames, wherein each frame is divided into M=8 subframes (subframe), and each subframe has L=6 OFDM Access (OFDMA) symbols. According to the definition of the IEEE 802.16m standard, a physical resource block is defined as consecutive L symbols in the time domain and K=18 consecutive subcarriers in the frequency domain. Therefore, there are N resource blocks in a subframe, and the value of N is determined by the system bandwidth.

[0025] Such as figure 2As shown, the wireless communication system 200 may include one or more transmitting devices (hereinafter referred...

Abstract

A method for subblock generation in a wireless communication system includes receiving, by a subblock generator, one or more data blocks, and selecting, based on one or more criteria, one or more functional blocks and an operational order of the one or more functional blocks. The method also includes processing the received one or more data blocks using the selected one or more functional blocks in the selected operational order to generate a plurality of data subblocks, and transmitting the plurality of data subblocks to the plurality of receiving devices. The method further includes transmitting, to the plurality of receiving devices, location information for each of the plurality of data subblocks.

Description

technical field [0001] The present disclosure relates to methods and devices for communication systems, and more particularly to methods and devices for wireless communication systems. Background technique [0002] Wireless communication systems allow wireless devices to communicate without a wired connection. As wireless systems are widely integrated in daily life, the demand for wireless communication systems supporting multimedia services such as text, audio, video, files, and website downloads is also increasing. Therefore, various wireless communication protocols and transmission control mechanisms have been developed to meet the growing demands of multimedia services over wireless communication networks and to enhance the performance of these multimedia services. An exemplary transmission control mechanism for transmitting packet data units (PDUs) in wireless systems is Hybrid Automatic Repeat Request (HARQ). [0003] Generally, there are two main variants of the HAR...
