Embodiment Construction

[0029] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] The HARQ packet length adaptive method and transmission system involved in the present invention calculate the channel error by adding a HARQ packet length adaptive module (or packet length adaptor) and according to the retransmission information generated by the HARQ mechanism. The bit rate e, calculates the optimal maximum HARQ data packet length according to the bit error rate e.

[0031] The packet length adaptive module (packet length adaptor) is used to interact with the HARQ entity, including an initialization assignment module and an adaptive module, the initialization assignment module determines environmental parameters according to the network environment, and the adaptive module is used to receive and count The transmission result of the HARQ data packet sent by the HARQ entity, the adaptive module is also used ...

Abstract

The invention discloses a packet length adaptive adjustment method for a hybrid automatic repeat request (HARQ) packet in a wireless system. The method comprises the following steps that: a packet length adaptive module of the HARQ packet is set and initiated; an HARQ entity acquires a transmission result of the HARQ packet and transmits the transmission result to the packet length adaptive module; and the packet length adaptive module determines the maximum HARQ packet length adaptive value according to the transmission result and transmits the adaptive value to the HARQ entity which controls the length of the HARQ packet interactively. The invention also relates to a transmission system. In the invention, the packet length adaptive module is set, so that the maximum HARQ packet length of the HARQ entity can be adjusted to adapt to the change of a network environment; and particularly, the effective utilization rate of a network bandwidth can be optimized under an unstable or relatively poor wireless environment.

Description

technical field [0001] The invention relates to the field of mobile communication systems, in particular to a method and a transmission system for adaptively adjusting the length of a HARQ data packet by a HARQ entity as the wireless network environment changes in a wireless system. Background technique [0002] With the development of wireless broadband communication technology, how to effectively use network bandwidth to improve data transmission efficiency and signal transmission quality to ensure the reliability of information transmission has always been a research topic in the field of wireless transmission. [0003] HARQ (Hybrid Automatic Repeat Request) is an error control technology that combines FEC (Forward Error Correction) and ARQ. Compared with previous ARQ technologies, it has higher retransmission efficiency The change of the physical channel can be detected more timely, which is mainly reflected in the gain generated by combining during the second retransmis...
