Abstract

The present application relates to a spectrum profile adjustment method and apparatus. A mobile device or an access point adjusts a spectrum profile of a current channel from a first bandwidth to a second bandwidth when an adjacent channel of the current channel is occupied, or the access point adjusts a spectrum profile of an area covered by the access point from the first bandwidth to the second bandwidth when the area covered by the access point is a busy area. Because the second bandwidth is smaller than the first bandwidth, the bandwidth of a spectrum profile can be decreased when an adjacent channel is occupied or a local area is busy according to the method and apparatus of the present application. As a result, even if a transmitted signal approximates the spectrum profile, interference to an adjacent channel can be reduced to make the adjacent channel usable as the bandwidth of the spectrum profile has been decreased. Therefore, the utilization rate of spectrum can be improved.

Description

Spectrum template adjustment method and device

Technical field

The present application relates to the field of communications, and in particular, to a spectrum template adjustment method and apparatus.

Background technique

The spectrum template refers to the maximum range of power distribution in the frequency domain after the transmitted signal passes through the RF chain. The bandwidth of the spectrum template refers to the bandwidth occupied by the signal power of the channel (eg, CH0) as the distance between the frequency and the center frequency of the signal increases, such as the power attenuation of the signal relative to the center frequency. At the time, the occupied bandwidth is -40dB bandwidth.

Typically, the spectral mask of a communication device is designed for a single frequency band and, therefore, does not take into account interference to adjacent channels.

detailed description

The embodiment of the present application can be applied to a Wireless Local Area Networks (WLAN) scenario. In the WLAN, an access point (AP) and a mobile device can be included. Wherein, under the coverage area of one AP, there can be at least one mobile device STA, and each of the at least one mobile device communicates with the AP through a respective channel. For example, if the channel of the first mobile device is CH0, the adjacent channels are CH0-1 and CH0+1.

The technical solutions in the embodiments of the present application will be further described below with reference to the accompanying drawings in the embodiments of the present application. The description is clear and complete, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

A spectrum template adjusting apparatus disclosed in the embodiment of the present application, as shown in FIG. 1 , includes:

The first determining module 101 is configured to determine whether an adjacent channel of the current channel is occupied;

The first adjustment module 102 is configured to adjust a spectrum template of the current channel from a first bandwidth to a second bandwidth, where the second bandwidth is smaller than the first bandwidth, if the adjacent channel is occupied.

The device in this embodiment can be set on the transceiver. In an actual application, on the one hand, the PA can be operated in a linear state by adjusting the backoff value of the power amplifier PA on the transceiver to adjust the bandwidth of the spectrum template. On the other hand, the second bandwidth may be a preset fixed value or may not be set. In the adjustment, it may be smaller than the first bandwidth.

In the prior art, the transceiver spectrum template is designed for a single frequency band. When the transmitted signal is very close to the template, the power amplifier PA is in a non-linear state (Rapp model), which has strong neighbor interference, and is strong. Adjacent-band interference can cause adjacent channels or alternate channels on both sides of the current channel to be unusable, thus seriously reducing spectrum utilization.

The device described in this embodiment reduces the bandwidth of the spectrum template of the current channel when the adjacent channel is occupied, so that the interference to the adjacent channel can be reduced, so that the signals of the adjacent channels are The Signal to Interference plus Noise Ratio (SINR) becomes larger, thereby improving the throughput of adjacent channels and achieving the purpose of improving spectrum utilization.

When the second adjusting module learns that the adjacent channel is not occupied, the second adjusting module may restore the bandwidth of the spectrum template to the state before the adjustment. .

Generally, in the case where the bandwidth of the spectrum template is reduced, the linearity of the power amplifier in the mobile device or the access point becomes high, thereby causing the efficiency of the power amplifier to be reduced, so that the adjacent channel is not occupied. It is not necessary to maintain the bandwidth of the spectrum template occupied by the current channel in the second bandwidth from the perspective of the efficiency of the power amplifier. Therefore, in this embodiment, if the adjacent channel is not occupied, the current channel is occupied. The bandwidth of the spectrum template is restored to the first bandwidth.

The template bandwidth can reduce the interference of each mobile device to its adjacent channel, and if the spectrum template of the access point itself is reduced, the access point can also reduce the interference to its adjacent channel, thereby Improve spectrum utilization in the region.
