In the present embodiment, related first base station is macro base station, and the second base station is small base station；Alternatively, first base station For small base station, the second base station is macro base station.

During specific implementation, the user equipment in the present embodiment be can be applied in Fig. 1 embodiment, the user equipment Can transmitting uplink data be carried out with small base station and macro base station respectively.Wherein, transmitting uplink data be user equipment to macro base station/ Small base station sends the process of upstream data.User equipment monitors macro base station/small base station Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as: PDCCH), when user equipment detects that macro base station or small base station dispatch the user Equipment, and ascending resource etc. is distributed for the user equipment, according to scheduling information, physically row shares channel to the user equipment Upstream data is sent to macro base station or small base station on (Physical Uplink Shared Channel, referred to as: PUSCH).

In the case that first base station stops uplink scheduling user equipment, the user equipment and first base station stop upper line number According to transmission, in a period of the user equipment and first base station stop transmitting uplink data, first base station can not know that user sets Standby power headroom.When user equipment carries out transmitting uplink data with first base station again, the processor 201 of user equipment is obtained Take the power headroom of the power headroom of the activation carrier wave of first base station and the activation carrier wave of the second base station, and swashing first base station The power headroom reporting of the power headroom of mobile load wave and the activation carrier wave of the second base station is to first base station.

User equipment can by power headroom reporting (PHR) by its current transmission moment first base station activation carrier wave power (i.e. user equipment all compositions within the scope of its maximum transmission power carry the power headroom of the activation carrier wave of surplus and the second base station The maximum power that can be transmitted on wave subtracts power consumed by current transmitting uplink data, if the upstream data of component carrier Transmission has been over the user equipment maximum transmission power, then according to preset rules with the user equipment emission maximum function Rate is limited to send upstream data) it is sent to base station.In the present embodiment, the processor 201 of user equipment user equipment again When the secondary progress transmitting uplink data with the first base station, the power headroom and second of the activation carrier wave of first base station is obtained respectively The power headroom of the activation carrier wave of base station.Wherein, the power headroom of the activation carrier wave of first base station refers to user equipment in the first base The maximum power that can be transmitted on each the activation carrier wave stood subtracts current user equipment in each activation of first base station Actual power consumed by the transmitting uplink data of carrier wave, the power headroom of the activation carrier wave of the second base station refer to user equipment The maximum power that can be transmitted on each activation carrier wave of two base stations subtracts user equipment in each activation of the second base station Actual power consumed by the transmitting uplink data of carrier wave.It is several that first base station has several activation carrier subscriber equipment that will obtain The power headroom of carrier wave, the power headroom that the second base station has several activation carrier subscriber equipment that will obtain several carrier waves.If The activation carrier wave of first base station and the activation carrier wave transmission power actually required of the second base station be more than the user equipment most Big transmission power is then limited with the maximum transmission power of the user equipment according to preset rules and carries out the transmission of upstream data.

Then, user equipment reports the activation carrier wave of the first base station by transmitter 202 to the first base station The power headroom of power headroom and the activation carrier wave of second base station, so that the downlink path loss of first base station estimation user equipment And coordinate ascending resource distribution etc., which is scheduled.

User equipment provided in an embodiment of the present invention, be applied to heterogeneous network in, the heterogeneous network include macro base station and Small base station, covering hole area or traffic hotspots region of the small base station deployment in the macro base station, the macro base station and institute It states small base station and provides service by carrier aggregation technology for user equipment, comprising: processor, in user equipment and the first base It stands in the case where stopping transmitting uplink data, if the user equipment carries out upstream data biography with the first base station again It is defeated, obtain the power headroom of the power headroom of the activation carrier wave of first base station and the activation carrier wave of the second base station；Transmitter is used for The power headroom of the activation carrier wave of the first base station and the activation carrier wave of second base station are reported to the first base station Power headroom realizes in heterogeneous network, when first base station when not having scheduling user's set for a period of time, the first base station Can timely learning user equipment activation carrier wave on power headroom, to be adjusted according to the power headroom to user equipment Degree avoids first base station to the problem for crossing scheduling or user equipment emergent power deficiency of user equipment.

Several specific embodiments are used below, to the possible implementation of the present invention, are described in detail.

A kind of possible implementation, the case where the user equipment and the first base station stop transmitting uplink data Under, processor 201 starts timer；The case where the user equipment carries out transmitting uplink data with the first base station again Under, if the timer expiry, processor 201 obtains the power headroom and described second of the activation carrier wave of the first base station The power headroom of the activation carrier wave of base station, transmitter 202 report the activation carrier wave of the first base station to the first base station The power headroom of power headroom and the activation carrier wave of second base station.

Alternatively possible implementation carries out transmitting uplink data with the first base station again in the user equipment In the case where, if the user equipment is under the service of the first base station from the suspend mode in connected state discontinuous reception modes State switchs to the activated state in the connected state discontinuous reception modes, and processor 201 obtains the activation carrier wave of the first base station Power headroom and second base station activation carrier wave power headroom.Transmitter 202 reports described to the first base station The power headroom of the activation carrier wave of the power headroom and second base station of the activation carrier wave of first base station.

Specifically, discontinuous reception (Discontinuous Reception, referred to as: DRX) is divided to two kinds: the non-company of Idle state Continuous reception pattern and connected state discontinuous reception modes, connected state discontinuous reception modes further include activated state and dormant state.Its In, connected state discontinuous reception modes allow user equipment periodically to stop in the state of keeping wireless heterogeneous networks to connect It is converted between dormancy state and activated state.When user equipment is in activated state, the receiving antenna of user equipment is opened, so that user sets Standby to receive downlink data, user equipment can also send upstream data in activated state, when user equipment is in dormant state, use The receiving antenna of family equipment is closed, and user equipment cannot receive downlink data, while can not send upstream data.Idle state is non- Continuous reception pattern also as connected state discontinuous reception modes, is divided into activated state and dormant state.

In another possible implementation, the processor 201 is obtained in the user equipment and the first base station First power headroom of the activation carrier wave of second base station before stopping transmitting uplink data, and, in the user equipment and institute It states and carries out transmitting uplink data with the first base station again to the user equipment when first base station stops transmitting uplink data When during second base station activation carrier wave the second power headroom；If second power headroom compares described first The variable quantity of power headroom has been more than pre-determined threshold, processor 201 obtain the user equipment again with the first base station The second power headroom of activation carrier wave and the activation of second base station for carrying out first base station when transmitting uplink data carry The third power headroom of wave, the transmitter 202 report the second of the activation carrier wave of the first base station to the first base station The third power headroom of power headroom and the activation carrier wave of second base station.

During specific implementation, user equipment first base station activation carrier wave and the second base station activation carrier wave it is total Power is constant, and therefore, the function of the activation carrier wave of first base station has been reacted in the variation of the power headroom of the activation carrier wave of the second base station The variation of rate surplus illustrates the activation carrier wave of first base station when the power headroom variation of the activation carrier wave of the second base station is little Power headroom variation it is little.By taking specific time shaft as an example, the present embodiment is described in detail.Fig. 3 is that the present invention is real A power headroom reporting time shaft schematic diagram one is applied, as shown in Figure 3, on time shaft t, with Transmission Time Interval (Transmission Time Interval, abbreviation TTI) be unit, including TTI1(t1-t2), TTI2(t2-t3), TTI3 (t3-t4).Wherein, the time of upstream data is sent to first base station for user equipment on TTI1 and TTI3.Specifically, it handles Device 201 obtains the activation carrier wave of second base station before the user equipment and the first base station stop transmitting uplink data The first power headroom PH1, i.e., before the t2 time, obtain PH1；The acquisition of processor 201 stops in user equipment and first base station The second base station swashs during when only carrying out transmitting uplink data with first base station again to user equipment when transmitting uplink data Second power headroom PH2 of mobile load wave obtains PH2 to during t3 in t2.
