Problems solved by technology

[0005] If the time granularity of a transmission subframe with an earlier transmission time is smaller than that of a transmission subframe with a later transmission time, one transmission subframe with a later transmission time corresponds to multiple transmission subframes with an earlier transmission time. When the data to be transmitted on a transmission subframe with an earlier transmission time does not always exist, the vacant transmission power on the transmission subframe with an earlier transmission time cannot be allocated to the transmission subframe with a later transmission time, resulting in power resource waste, low power usage

Embodiment 1

[0118] In the current communication system, for example, an LTE (Long Term Evolution, long term evolution) communication system or a WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) communication system, etc. A communication system includes a base station and a UE, see Picture 1-1 shown. The UE simultaneously transmits uplink data in the first target subframe and the second target subframe with different subframe lengths, and the frequency of the first target subframe is different from the frequency of the second target subframe.

[0119] For example, see Figure 1-2 , the subframe length of the first target subframe is greater than the subframe length of the second target subframe, then the frequency of the first target subframe is lower than the frequency of the second target subframe, and one first target subframe corresponds to multiple second target subframe. Therefore, although the uplink data transmitted by the UE on the first ta...

Embodiment 2

[0142] see figure 2 , figure 2 It is a structural block diagram of a base station provided by an embodiment of the present invention. The base station may have relatively large differences due to different configurations or performances, and may include one or more second processors 201 and second transmitters 202 .

[0143] The second processor 201 is configured to acquire the first uplink channel information on the first target subframe and the second uplink channel information on the second target subframe, where the transmission time of the second target subframe is the same as that of the first target subframe The transmission time overlaps, the second target subframe and the first target subframe have different subframe lengths, and the second target subframe and the first target subframe belong to different base stations or different cell groups;

[0144] The second processor 201 is further configured to determine the first time offset of the first control subframe a...

Embodiment 3

[0154] The embodiment of the present invention provides a power allocation method, which is applied in UE, see Figure 3-1 , the method includes:

[0155] Step 301: The UE determines a first start moment of a first control subframe and a second start moment of a second control subframe.

[0156] In the current communication system, the UE accesses different base stations or different cell groups at the same time. Before the UE transmits data to the base station, the UE obtains the transmission subframes corresponding to different base stations, which are called the first target subframe and the second target subframe respectively. subframes; or, the UE acquires transmission subframes corresponding to different cell groups, which are called the first target subframe and the second target subframe respectively.

[0157] The transmission time of the second target subframe overlaps with the transmission time of the first target subframe, the second target subframe and the first t...

Abstract

The invention discloses a power distribution method and device, which belong to the technical field of communication. The method includes: the UE determines the first start time of the first control subframe and the second start time of the second control subframe, and determines whether the priority of the first target subframe is based on the first start time and the second start time Higher than the priority of the second target subframe; if the priority of the first target subframe is higher than the priority of the second target subframe, according to the first uplink channel information and the second uplink channel information, for the UE in the first target subframe The base station or cell group where the subframe is located allocates power, and allocates the reserved power of the UE to the base station or cell group where the second target subframe is located; if the priority of the first target subframe is lower than that of the second target subframe stage, according to the first uplink channel information and the second uplink channel information, allocate power to the base station or cell group where the UE is located in the second target subframe, and allocate the reserved power of the UE to the base station or cell group where the UE is located in the first target subframe Save power.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for power distribution. Background technique [0002] In the current communication system, UE (User Equipment, user equipment) may simultaneously access multiple cell groups, and different cell groups may have transmission subframes with different time granularities; for ease of description, the UE simultaneously accesses the first cell group and the second cell group as examples, the first cell group corresponds to the first transmission subframe, and the second cell group corresponds to the second transmission subframe; the first transmission subframe and the second transmission subframe have different time granularities; When the UE transmits data to the base station, the UE carries the data to be transmitted in the first transmission subframe and the second transmission subframe, and allocates the first transmission power to the first transm...
