Problems solved by technology

However, when the noise floor is measured by cell, in order to reduce the overload, the largest sector floor noise is generally taken, which will affect the resource allocation of other sectors, reduce the uplink traffic, and cause a waste of frequency band resources

Embodiment Construction

[0048]The basic idea of ​​the present invention is: by setting the noise floor for each sector in the cell, and adjusting the noise floor of each sector in the cell according to the RTWP measured by the base station, so that the noise floor of each sector reflects the With the real noise floor of the sector, the base station can allocate resources more reasonably, the resource utilization rate is higher, the service flow obtained is higher, and the overload rate of the cell is reduced. The noise floor adjustment of the sector in the invention is completed by the base station, which reduces the complexity of the communication system.

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

Abstract

The invention discloses a method for regulating back noise of a partition sector, which comprises the following steps: whether users are in the sector is judged, if no user is in the section, sector RTWPmeas periodically measured by a base station is compared with current back noise RTWPk of the sector; if the RTWPmeas is less than the RTWPk, the RTWPk is reduced by a step length; if the RTWPmeas is equal to the RTWPk, no treatment is needed; and if the RTWPmeas is more than the RTWPk, the RTWPk is increased by a step length. The base station periodically measures the RTWPmeas of each sector in a subdistrict and filters the RTWPmeas to obtain RTWPfmeas; whether users are in the section is judged currently, if no user is in the section, the RTWPfmeas is compared with the RTWPk; if the RTWPfmeas is less than the RTWPk, the RTWPk is reduced by a step length; if the RTWPfmeas is equal to the RTWPk, no regulation is needed; and if the RTWPfmeas is more than the RTWPk, the RTWPk is increased by a step length. The invention also discloses a device for realizing the method and is simple and practical.

Description

technical field [0001] The invention relates to noise floor adjustment technology, in particular to a method and device for adjusting noise floor by sectors. Background technique [0002] Following the introduction of High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) in Release 5 of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), High Speed ​​Uplink Packet Access (HSUPA) was added in Release 6 of 3GPP , High SpeedUplink Packet Access) technology. By introducing fast uplink packet scheduling based on the base station (NODE B) and fast uplink hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat reQuest) retransmission, as well as adopting technologies such as multi-code transmission and a shorter 2ms transmission time interval, the uplink Provide up to 5.76M service rate. Since the uplink shared resource is noise rise (ROT), or the total power received by NODE B, the noise floor of the cell has a gre...
