Problems solved by technology

The PCP / AP randomly selects links to measure the spatial multiplexing in the subsequent SPs. The success rate of this random selection is very low, and the SPs capable of spatial multiplexing cannot be fully multiplexed, and the system throughput cannot be achieved. get the boost they deserve
At the same time, additional frame exchanges will be generated during the measurement process, which reduces the communication efficiency of the entire system

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Without loss of generality, the antenna model used in this case is as follows image 3 As shown, it is a non-ideal antenna model, that is, there is mutual coverage between sectors. The shadow in the figure is the antenna sidelobe coverage area, and the blank sector range is the main lobe coverage area, which is also the ideal antenna coverage area. The application scenarios of this case are as Figure 4 As shown, the 60GHz wireless network includes a master device (PCP / AP) as a coordinator, 6 sub-devices (DEV) and their sector distribution (M sectors, M=8). In this scenario, device A requests to communicate with device B, which is arranged in SP e In communication, device C requests to communicate with device B, and device E requests to communicate with device F, respectively in SP c1 and SP c2 middle.

Abstract

The invention discloses a spatial multiplexing method for intercepting millimeter wave high speed communication system wave beam sectors. When a device participating wave beam forming transmits a training sequence, other devices intercept signals in an omnidirectional antenna mode, and a list is built according to interception results of all sectors of a transmitting device, when the devices request SP, interception lists of optimum transmitting sectors obtained by self wave beam forming and local sectors are reported to a PCP / AP. The PCP / AP stores the information, thereby having all the sector interception lists of the devices needing to communicate in the SP, and under the condition that the devices are not indicated to carry out spatial multiplexing measurement, the PCP / AP can obtain disturbed conditions among links, so that the links are effectively selected for carrying out spatial multiplexing.

Description

technical field [0001] The invention relates to a space multiplexing method for beam sector interception of a millimeter wave high-speed communication system, which belongs to the communication technology. Background technique [0002] WPAN (Wireless Personal Area Network, Wireless Personal Area Network) is a new type of communication network, and it is also one of the fastest growing areas of the current network. It is proposed to realize the wireless communication network technology with small activity radius, rich business types, specific groups, and wireless seamless connection. It can effectively solve the "last few meters of cable" problem. With the advancement of technology, wireless communication devices have increased rapidly, and various handheld communication devices have appeared one after another, and the demand for short-distance transmission of multimedia applications is increasing day by day. This requirement makes wireless short-distance communication must...
