Definitions
- the present application relates to the field of communications technologies, and in particular, to a power configuration method, a user equipment, and a base station. Background technique
- LTE-A Long Term Evolution-Advanced; Advanced Long Term Evolution
- CA Carrier Aggregation
- the frequency of two or more component carriers is aggregated to obtain a wider transmission bandwidth.
- the spectrum of each component carrier may be adjacent contiguous spectrum or within the same frequency band. The non-adjacent spectrum is even a discontinuous spectrum in different frequency bands.
- the LTE-A user equipment can simultaneously access multiple component carriers for data transmission and reception according to its capabilities and service requirements.
- carrier aggregation between base stations is introduced, that is, DC (Dual Connectivity).
- the base stations are non-ideal backhaul (Backhaul), and data cannot be transmitted between base stations in real time.
- the two base stations may be unsynchronized, that is, there is an arbitrary time difference between the start times of the downlink transmission subframes of the two base stations, and in this asynchronous DC scenario, the user equipment UE is sent to the two network sides.
- the multiple uplink channels of the device may overlap each other. For details, refer to FIG. 1 , the first channel that the user equipment UE sends data to the secondary network side device SeNB and the second data that sends data to the primary network side device MeNB.
- the channel and the third channel overlap, the first part of the first subframe j where the first channel is located and the second subframe i where the second channel is located are overlapped, and are referred to as a first overlapping area for convenience of description, further

- the power configuration for each subframe is performed.
- the method is: assigning powers of the first subframe j and the second subframe i according to priorities of the first channel and the second channel, where each part of the first subframe J is transmitted at equal power, that is, the first All symbols of subframe J are transmitted with equal power, even if there is a second overlapping region, so that the third subframe i+1 can only be transmitted with the remaining power after the first subframe j is allocated.
- the first channel is PUCCH (Physical Uplink Control Channel).
- the second channel is a physical uplink shared channel (PUSCH).
- PUSCH Physical Uplink shared channel

- the power of the first channel remains unchanged even if the third channel is a PUCCH channel, that is, the priority of the third channel is higher than or equal to the priority of the first channel, because the UE is in a time segment.
- the maximum transmit power is limited, and the third channel of the third subframe i+1 can only be allocated to the remaining power, so the power allocated by the third subframe may not reach the required power, so Affects the transmission performance of the third subframe.
- the primary network side device is responsible for transmitting and receiving all RRC (Radio Resource Control) control information of the UE when the UE is in the DC mode, and the secondary network side device does not send or receive such information. Therefore, if the type of the uplink channel sent by the UE to the two network side devices is the same or the uplink control information carried by the uplink channel has the same priority, the uplink channel sent to the primary network side device is generally considered to be more important, and the uplink should be preferentially allocated.
