Problems solved by technology

[0025] One disadvantage of the above scheme is that when a VoIP user 130 allocated with sticky allocation shares the same resource with a Best Effort (BE) data user 140 allocated with sticky or non-sticky 110, and when the current BE user 140 occupies the resource 110 due to its pending H-ARQ retransmission, the VoIP user 130 has to wait until the pending H-ARQ retransmission of the BE user 104 ends successfully before being able to regain the channel resource 110 Or reach the maximum number of retransmissions for BE users 140
This has the potential to cause excessive latency and degraded Quality of Service (QoS) for latency-sensitive applications such as VoIP

Embodiment Construction

[0080] The following description is given to enable a person skilled in the art to make and use the invention. The general principles described herein may be applied to other embodiments and applications than those described in detail below without departing from the spirit and scope of the invention as defined herein. The present invention is not limited to the examples given, but is intended to cover the widest scope consistent with the principles and features disclosed herein.

[0081] see image 3 , shows a flowchart of an embodiment of implementing wireless resource sharing in an OFDMA system. exist image 3 In the illustrated embodiment, the process for a receiver to receive information in the system begins at step 101 . In step 103, the receiver waits for a new sub-packet to arrive. During step 103, after receiving the subpacket, the receiver determines whether a new H-ARQ sequence indicator has been received. According to the present invention, a new H-ARQ sequence ca...

Abstract

A physical layer packet format and signaling method is provided to minimize signaling overhead wherein multiple users share air interface resources to improve efficiency in orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA) communication systems.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a new method for sharing wireless resources in the wireless communication system. Background technique [0002] In a wireless multiple access communication system, all wireless users in a specific cell share wireless traffic channel resources (eg, bandwidth and time interval). Since the effective allocation of traffic channel resources among various wireless users directly affects the overall utilization of traffic channel resources and the quality of service experienced by each wireless user, it is very critical to ensure the high performance of all these users. [0003] One method of providing wireless communication services is to utilize existing Orthogonal Frequency Division Multiplexing (OFDM) technology. Other techniques for providing wireless communication among multiple users include time division multiple access (TDMA) which divides wireless communicat...
