Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.

It should be noted that, the embodiment of the present invention can be for a kind of Access Network, macro base station and micro-base station are comprised at this Access Network, and macro base station and micro-base station are two different base stations, the downlink data of macro base station transmission terminal equipment in Access Network, the upstream data of micro-base station receiving terminal apparatus in Access Network.

On the one hand, the embodiment of the present invention provides a kind of method of uplink, as shown in Figure 1, comprising:

101, the memory of terminal equipment from Access Network or the described terminal equipment information that gets parms.

Wherein, parameter information comprises following one or more combinations: the PL(Pathloss in terminal equipment and Access Network when micro-base station communication, path loss), compensating parameter, the through-put power control TPC adjusted value of the PL of the PL of terminal equipment during with micro-base station communication while communicating by letter with the macro base station in Access Network with respect to terminal equipment, compensating parameter is used to terminal equipment and determines PL when terminal equipment is communicated by letter with the macro base station in Access Network etc.It should be noted that, compensating parameter can comprise that macro base station in Access Network sends transmitting power or a default numerical value of common reference information CRS, so that the PL of terminal equipment while utilizing compensating parameter to communicate by letter with the macro base station in Access Network to terminal equipment processes.

It should be noted that, Access Network can repeated obtain parameter information and is sent to terminal equipment, and terminal equipment can repeat 101-102, thus terminal equipment can be periodically, semi-statically or real-time definite uplink transmission power.

In the present embodiment, the terminal equipment PL of one or more values during as terminal equipment and micro-base station communication that can prestore in memory, for example: the PL when terminal equipment prestoring in terminal equipment and micro-base station communication is 0, when in the cell range in macro base station of the position of terminal equipment, and outside the cell range of micro-base station time, Access Network can trigger up-downgoing separation mechanism by conventional technological means, the downlink data of macro base station transmission terminal equipment, the upstream data of micro-base station receiving terminal apparatus.Now, owing to not receiving the downlink data of micro-base station, terminal equipment can be using fixed value 0 as terminal equipment and PL when micro-base station communication, and according to PL=0, the uplink transmission power of computing terminal equipment.

Further, the path loss when terminal equipment prestoring in terminal equipment and micro-base station communication can be for multiple, in the time that Access Network triggers up-downgoing separation mechanism, terminal equipment can obtain one of them according to preset rules from the multiple fixed values that prestore, and PL during using this obtained fixed value as terminal equipment and micro-base station communication.

102, terminal equipment is determined uplink transmission power according to described parameter information, and utilizes uplink transmission power to send upstream data to described micro-base station.

In the present embodiment, terminal equipment can be determined uplink transmission power according to parameter information by conventional technological means, for example:

The technological means that can record according to existing protocol, path loss PL during according to terminal equipment and micro-base station communication obtains PRACH(Physical Random Access Channel, Physical Random Access Channel) and PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel) ascending power.

Transmitting power more for example: macro base station also can obtain the maximum transmission power in the community of micro-base station, for example CRS(Common Reference Signal, downlink reference signal).Wherein, the power when maximum transmission power in community refers to base station to cell edge transmission downlink data.And the PL during as terminal equipment and micro-base station communication is sent to terminal equipment using the numerical value of the maximum transmission power in a community that is more than or equal to micro-base station.

202a, determines uplink transmission power according to described parameter information, and utilizes determined uplink transmission power to send upstream data to described micro-base station.

Arranged side by side, as shown in Figure 2 b, the method for the uplink that the embodiment of the present invention provides can comprise:

201b, terminal equipment receives described macro base station by the parameter information of broadcast transmission.

For example: micro-base station can be sent to macro base station and by macro base station broadcast transmission using the transmitting power of the CRS of micro-base station as mean value, wherein the terminal equipment in up-downgoing separation scene can be using mean value the PL when with micro-base station communication.

Again for example: PL when macro base station also can obtain a terminal equipment in up-downgoing separation scene and micro-base station communication by the technological means of the present embodiment is broadcast to this terminal equipment.
