Problems solved by technology

However, when the reserved SP overlaps with other SPs, it may be interfered by the neighboring BSS or this BSS, and establishing a protection period for the SP can avoid interference
[0009] However, in the prior art, only when the network controller has joined the central cluster, the site of the SP must be required to establish a protection period, but if the network controller does not join the central cluster, the site of the SP will automatically Deciding whether to establish a protection period for the SP, but the site of the SP cannot effectively judge when the protection period should be established, resulting in increased protection overhead due to the blind establishment of the protection period, and interference due to the omission of the scheduling information of the adjacent BSS and the failure to establish the protection period

Abstract

Embodiments of the present invention provide a network controller, a site, and a method for establishing a protection period, relate to the field of communications, and reduce the overhead of establishing a protection period and reduce interference. The network controller provided by the embodiment of the present invention includes: an obtaining unit, configured to obtain scheduling information of neighboring network controllers of the first network controller; and a determining unit, configured to determine the time and frequency between other access periods and the first SP The scheduling unit is configured to set the protection period configuration information of the first SP according to the interference situation received by the first SP and the overlapping situation determined by the determining unit, wherein the protection period configuration information includes the first indication information or the first Two indication information, the first indication information is used to indicate that the protection period must be established for the first SP, and the second indication information is used to indicate that the protection period is allowed to be established for the first SP; the first sending unit is used to send the information of the first SP to the station. Protection period configuration information to enable the site to determine whether to establish a protection period for the first SP.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network controller, a station, and a method for establishing a protection period. Background technique [0002] 60GHz and 45GHz wireless communication belongs to the category of millimeter wave communication. Millimeter Wave (Millimeter Wave) refers to electromagnetic waves with a frequency in the range of 300GHz to 30GHz. Its wavelength is 1-10mm, so it is called millimeter wave. It has a wide range of applications in many fields such as communication, radar, navigation, remote sensing, and radio astronomy. As an important branch of millimeter wave communication, 60GHz and 45GHz communication has the following advantages: [0003] (1) The channel capacity is large. The bandwidths of the 60GHz and 45GHz bands are the larger license-exempt bands. The license-free bandwidth exceeding 5GHz makes 60GHz technology have great potential in terms of capacity and flexibility, and ma...
