Embodiment 1

[0066] An embodiment of the present invention provides a superframe-based cooperative communication method, such as Figure 7 As shown, the method includes:

[0067] Step S11, broadcasting a frame carrying a cooperative communication information unit, and initiating a cooperative communication request;

[0068] S (or D) may broadcast a cooperation request by sending a beacon frame or a cooperation communication frame carrying a cooperation communication information unit.

[0069] Step S12, receiving feedback information sent by a neighbor device that can act as a relay device, and selecting at least one neighbor device from the neighbor devices that sent the feedback information as a relay device;

[0070] For the cooperation request initiated by S (or D), the neighbor device responds as R, that is, the neighbor device that can act as a relay device sends feedback information that can act as R, and S (or D) receives the feedback information from the neighbor devices that can ...

Embodiment 2

[0077] The embodiment of the present invention provides a superframe-based cooperative communication method, and the ECMA-368 system adopts the time division mode, and the time division is based on the superframe (SF) and medium access slot (MAS) as an example to illustrate the embodiment of the present invention technical solutions. Such as Figure 9 As shown, the superframe-based cooperative communication method in this embodiment includes:

[0078] S21. Judging whether the channel quality of both communication parties is lower than a predetermined channel quality;

[0079] First of all, it is necessary to judge when to initiate cooperative communication according to the channel quality of the communication parties (S and D), that is, to judge whether the channel quality of the previous communication between S and D is lower than the predetermined channel quality; or to judge whether the real-time channel quality of S and D is low at the predetermined channel quality.

Abstract

The embodiment of the invention discloses a cooperative communication method and apparatus based on a super frame, which relates to the field of communication, realizes cooperative communication between neighboring apparatuses and improves the efficiency of data transmission. The cooperative communication method based on the super frame comprises the following steps of: broadcasting a frame carrying a cooperative communication information unit, and initiating a cooperative communication request; receiving feedback information, on the neighboring apparatus capable of serving as a relay apparatus, sent by the neighboring apparatuses, and selecting at least one neighboring apparatus as the relay apparatus from the neighboring apparatuses sending the feedback information; and indicating the relay apparatus as a data transmitting apparatus.

Description

technical field [0001] The present invention relates to the communication field, in particular to a superframe-based cooperative communication method and equipment. Background technique [0002] ECMA-368&369 (European Computer Manufacturers Association, [computer] European Computer Manufacturers Association) is an ultra-wideband (Ultra-wideband, referred to as UWB) technology industry standard jointly launched by the WiMedia Alliance and the European International Computer Manufacturers Association. It has become an ISO international standard in 2007. standard. Among them, taking ECMA-368 as an example, the standard describes technical specifications of a physical layer (PHY) based on multi-band OFDM modulation and a media access control layer (Media Access Control, MAC for short) of a distributed architecture. [0003] The ECMA-368 standard divides time into super frames (Super Frame, SF for short) on a channel. Such as figure 1 As shown, a superframe is a continuous and...
