Embodiment 1

[0129] Figure 14 It is a schematic diagram of the second base station determining its own transmission power (coverage) according to the signal and related information of the first base station according to the preferred embodiment 1 of the present invention, as shown in Figure 14 As shown, the second base station (LAA-eNB2) can receive the energy of the first base station (LAA-eNB1) (for example, the received power is -60dBm), and exceeds the preset threshold of carrier busy and idle (assuming threshold X -62dBm), but the second base station is not within the illustrated coverage of the first base station (for example, the preamble (Preamble code) (PRACH) can hear each other, but the data coverage (eg, PDSCH) cannot hear each other) .

[0130] The first base station obtains the right to use the unlicensed carrier (for example, it can be obtained through LBT competition).

[0131] The first base station transmits (broadcasts) a signal / channel (ie, occupancy signal, occupan...

Embodiment 2

[0146] Figure 15 is a schematic diagram of the first base station determining its own transmission power (coverage) according to the request of the second base station according to a preferred embodiment of the present invention, as shown in Figure 15As shown, the second base station (LAA-eNB2) is within the coverage of the first base station (LAA-eNB1). The second base station can hear the physical downlink shared channel (Physical Downlink Shared CHannel, PDSCH for short) of the first base station.

[0147] The first base station obtains the right to use the unlicensed carrier (for example, through LBT competition).

[0148] The first base station transmits (broadcasts) a signal / channel (ie, occupancy signal, occupancy signal) that occupies an unlicensed carrier.

[0149] The first base station sends (broadcasts) the transmission power used when occupying the unlicensed carrier this time.

[0150] The second base station receives the above signal / channel.

[0151] The ...

Embodiment 3

[0166] Figure 16 is a schematic diagram of the first base station and / or the self-serving UE requesting the second base station to reduce the transmit power according to a preferred embodiment of the present invention, as shown in Figure 16 As shown, the two base stations can hear each other (for example, the Preamble can hear, but the PDSCH cannot hear) and there is a certain coverage overlapping area. The UE served by the first base station is in a coverage overlap area (ie, may be interfered by the second base station).

[0167] The first base station (LAA-eNB1) and / or the user equipment (UE1) served by itself (UE1; only one UE is described in this example, but there can be more than one) sends a request to the second base station (LAA-eNB2) to the second base station Signal / channel with reduced transmit power. It is assumed that the first base station directly sends a dedicated Preamble to the second base station. For example, four dedicated Preambles are divided, eac...

Abstract

The invention discloses a non-authorized carrier occupation processing method, an apparatus, and a system. The method includes: a first base station determines the occupation of a non-authorized carrier; the first base station sends a signal / a channel of the non-authorized carrier and employed emission power information during the occupation of the non-authorized carrier, and the signal / channel and the emission power information are used for determining the maximum emission power of the non-authorized carrier employed by one or more second base stations. According to the method, the apparatus, and the system, problems that in the related technology, during the usage of the non-authorized carrier, interferences exist between adjacent base stations, and the area throughput is not high are solved, the interferences between the adjacent base stations during the usage of the non-authorized carrier are reduced, the usage of the non-authorized carrier between the base stations is coordinated, and the area throughput is effectively increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a processing method, device and system for unlicensed carrier occupation. Background technique [0002] Unlicensed carrier (license-free spectrum) refers to the spectrum (or carrier) that can be used directly without authorization under the relevant regulations (radio regulation) of government departments (such as the National Radio Regulatory Commission). For example, in our daily life, microwave ovens, remote control toy airplanes, wireless mice, wireless keyboards, high-fidelity wireless Internet access (Wireless Fidelity, referred to as WiFi), etc. all use unlicensed carriers. [0003] Since various devices can use unlicensed carriers, they may interfere with each other. If the interference is too large (for example, your own transmission makes the power received by the other party exceed -62dBm), it may cause the equipment that normally works on the unlicensed carrier to ...
