Method for adjusting working mode of home base station and processing method of working mode information

Technical field

The present invention relates to the field of communications, and in particular, to a method for adjusting a working mode of a home base station in a wireless communication system and a method for processing information of a working mode of a home base station. Background technique

In a wireless communication system, a base station refers to a device that provides services for a terminal. The base station communicates with the terminal through uplink and downlink. The downlink (forward) refers to the direction from the base station to the terminal, and the uplink (reverse) refers to the terminal to the base station. direction. Multiple terminals can simultaneously transmit data to the base station through the uplink, or can simultaneously receive data from the base station through the downlink.

The quality of wireless coverage in wireless communication networks is the key to affecting users' enjoyment of high-speed data, voice and video services. At present, in order to achieve seamless coverage of wireless communication networks, it is necessary to focus on addressing coverage problems in indoor and hotspot areas. There are two main schemes: one is to increase the number and density of macro base stations (Macro BS, also called Macro Cell); One is to install a small base station with low transmission power such as Femto BS (Femto Cell), Pico BS (also called Pico Cell). According to Shannon's law, using traditional macro base stations, which are close to the capacity limit of frequency use, and then adding more powerful macro base stations, will only cause more radiation pollution, and will not improve the indoor coverage. The use of small base stations such as home base stations and micro base stations can not only solve the coverage problems in indoor and hotspot areas, but also increase the system capacity in the existing spectrum resources.

The IEEE 802.16m team's system requirements document (IEEE 802.16m System Requirements) states that the home base station can provide services to all users, or only a specific set of Authorized users provide services. Usually, the home base station is powered by the user's own paid power system, so the method used to reduce the power consumption of the home base station is a problem to be solved.

In addition, there is no method in the prior art for reporting, collecting, and the like of the working mode information of the home base station. Summary of the invention

In addition, the base station receives any one of the home base station or the home base station group. After the base station sends a request to adjust its working mode, the working mode adjustment information is sent.

The present invention also provides a method for adjusting a working mode of a home base station, the method comprising: measuring, or receiving, a preset time-frequency resource by a home base station in a low-power operation mode, and receiving the received time according to the measured result or the received Information to adjust the working mode;

The working mode includes at least: a normal working mode, and/or a low power working mode. In addition, if the measurement result is that the energy on the time-frequency resource is greater than a preset power consumption increase threshold, the duration is greater than or equal to a preset first time length threshold, or in the time-frequency resource. When the preset information is received, the home base station adjusts the working mode to the normal working mode.

In addition, the preset information is a codeword in a preset codeword set.

FIG. 3 is a flowchart of a method for processing operation mode information of a home base station according to a third embodiment of the present invention.

Preferred embodiment of the invention

The basic idea of the present invention is that the base station adjusts the operating mode of the home base station by transmitting the mode of operation adjustment information to the home base station.

In addition, the home base station may periodically or irregularly send the current working mode information and/or the target working mode information to other base stations; or may send the current working mode information to other base stations after performing the current working mode adjustment, and the base station receives the The above working mode information is adjusted for Neighbor Advertisement Information (Neighbor Advertisement Message).

In addition, the terminal may send uplink information to the home base station by using a specific time-frequency resource, so as to adjust the working mode of the home base station; the home base station measures or receives the specific time-frequency resource, and performs a working mode according to the measured or received result. Adjustment. In the present invention, the working modes of the home base station are mainly divided into two categories: a normal working mode and a low power working mode. The low-power mode of operation can be further divided into different power levels (or low-power modes of operation subdivided into different power levels).

The BCH (Broadcast Channel) transmission period of the home base station in the low power operation mode may be greater than the transmission period of the BCH of the home base station in the normal operation mode.

In addition, the amount of information transmitted on the BCH of the home base station in the low power mode of operation may be less than the amount of information transmitted on the BCH of the home base station in the normal mode of operation. For example, in a low power mode of operation, the home base station may not transmit information that the secondary terminal is decoding.

However, the home base station in different working modes should include the auxiliary terminal on the BCH.

Ranging codeword (ranging codeword) related information (such as uplink time-frequency resource information that can be used to transmit Ranging codewords), so that the terminal can still provide the base station to the base station if the home base station is in a low-power mode of operation. Send the Ranging codeword.

In addition, the transmission period of the SCH (Synchronize Channel) of the home base station in the low power mode of operation may be greater than the transmission period of the SCH of the home base station in the normal mode of operation.

In addition, the transmission power of the home base station in the low power mode of operation may be less than the transmission power of the home base station in the normal mode of operation.

In addition, the home base station in the low power mode of operation can stop transmitting information (including the synchronization signal).

The invention will now be described in detail in conjunction with the drawings and embodiments.

First embodiment:

1 is a flow chart of a method for adjusting a working mode of a home base station according to a first embodiment of the present invention. In this embodiment, the base station (usually a macro base station) sends the working mode adjustment information to the home base station, and the home base station can adjust the working mode according to the information, which specifically includes the following steps:

Step 101: A base station (usually a macro base station) sends working mode adjustment information to the home base station through an air interface and/or a backbone network (Backbone, also called Backhaul). The base station may perform the step when receiving a request sent by the home base station to adjust its working mode.

101.

When the base station transmits the working mode adjustment information to the home base station through the air interface, the broadcast, or multicast, or unicast mode may be used.

When the base station sends the working mode adjustment information to the home base station, the terminal, and/or the relay station may be used.

(Relay Station, referred to as RS), and / or other base stations as relays.

The working mode adjustment information includes: identification information of the home base station or the home base station group that needs to be adjusted in the working mode; and may include one or more of the following information: working mode after adjusting the working mode (ie, the target working mode) The BCH transmission period (ie, the target BCH transmission period) after the operation mode adjustment is performed, and the SCH transmission period (ie, the target SCH transmission period) after the operation mode adjustment is performed, and the transmission power after the operation mode adjustment is performed.

If the different home base stations or the home base station group have mutually orthogonal or quasi-orthogonal spreading sequences, the base station may transmit the corresponding working mode adjustment information to the home base station or the home base station group by using a spread spectrum method.

The base station typically generates operational mode adjustment information based on the distribution of the home base station and the terminal (i.e., the location relationship of the home base station to the terminal, or the number of terminals that have entered, or have entered, and are about to enter the coverage of the home base station signal). Specifically, if the base station knows that there is no terminal near the home base station that can provide the service, that is, the number of terminals that have entered, or have entered, and are about to enter the coverage of the home base station (for example, within the coverage of the home base station synchronization channel) If it is 0, the base station generates and sends the working mode adjustment information, indicating that the home base station adjusts the working mode to the low power working mode; if the base station knows that the terminal in the vicinity of the home base station is capable of providing the service, that is, has entered, or has entered and If the number of terminals in the signal coverage area of the home base station is greater than 0, and the home base station is currently in the low power consumption mode, the base station generates and sends the operation mode adjustment information, indicating that the home base station adjusts the working mode to normal operation. mode.

The base station may also generate working mode adjustment information based on the location relationship between the home base station group and the terminal. Specifically, if the base station knows that there is no terminal in the vicinity of the home base station group, that is, the terminal within the signal coverage range (ie, the union of the signal coverage of all base stations in the home base station group) that has entered, or has entered, the home base station group. If the number is 0, the base station generates and sends the working mode adjustment information, indicating that all the base stations in the home base station group adjust the working mode to the low power working mode; Obtaining that there is a terminal near the home base station group, that is, the number of terminals in the signal coverage area that has entered, or has entered, and is about to enter the home base station group is greater than 0, and some or all of the base stations in the home base station group are currently in low power operation. In the mode, the base station generates and sends the working mode adjustment information, indicating that all the base stations in the home base station group adjust the working mode to the normal working mode.

Step 102: After receiving the working mode adjustment information, the home base station performs adjustment of the corresponding working mode.

Specifically, after receiving the working mode adjustment information, the home base station may determine whether the corresponding working mode adjustment needs to be performed according to whether the base station identifier of the home base station group or the group identifier of the home base station group to which it belongs is included, and if not, There is no need to adjust the working mode. If it is included, you can adjust the following:

If the current working mode of the home base station is different from the working mode indicated in the working mode adjustment information (ie, the target working mode), the home base station adjusts the working mode to the working mode indicated by the information;

If the current BCH transmission period of the home base station is different from the BCH transmission period indicated in the working mode adjustment information (ie, the target BCH transmission period), the home base station adjusts the transmission period of the BCH to the BCH transmission period indicated by the information;

If the current SCH transmission period of the home base station is different from the SCH transmission period indicated in the operation mode adjustment information (i.e., the target SCH transmission period), the home base station adjusts the transmission period of the SCH to the SCH transmission period indicated by the information.
