Take running on a computer terminal as an example, such as figure 2 As shown, the computer terminal may include one or more (only one is shown in the figure) processor 101 (the processor 101 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA), a processor 101 for storing Memory 103 for data, and transmission means 105 for communication functions. Those of ordinary skill in the art can understand that, figure 2 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device.

[0034] The memory 103 can be used to store software programs and modules of the application software, such as program instructions / modules corresponding to the control method of the device in the embodiment...

application example 1

[0071] Scenario description: The reference signal broadcast by the super cell is the reference signal power value transmitted by the macro station RRU, and the UE moves from Macro CP0 to Micro CP1.

[0072] Step S401, the UE reports the PHR after entering the Micro CP1, and the base station receives the PHR reported by the UE.

[0073] Step S402, the base station estimates the "calculated path loss" of the UE and the actual transmit power of the UE according to the PHR reported by the UE.

[0074] Step S403, the base station obtains the "actual path loss" from the UE to the macro-micro CP according to the actual transmit power of the UE and the smoothed power value maintained by each CP in the measurement window W. That is, the "actual path loss value" from the UE to the macro-micro CP is calculated according to the actual transmit power of the UE and the smoothed power value maintained by each CP in the measurement window W.

[0075] Step S404, the base station calculates th...

Abstract

The invention provides a method and device for adjusting uplink power. Wherein, the method includes: determining the first downlink path loss and the second downlink path loss, wherein the first downlink path loss is the downlink path loss measured by the user equipment UE, and the second downlink path loss is the actual downlink path loss; based on The difference between the first downlink path loss and the second downlink path loss generates power adjustment information, wherein the power adjustment information is used to adjust uplink power of the UE; and the power adjustment information is sent to the UE. The present invention solves the technical problem that the user equipment UE cannot accurately adjust the transmission power in the related art.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for adjusting uplink power. Background technique [0002] In the 3GPP LTE (Long Term Evolution) system, in order to avoid the problem of co-channel interference and related problems caused by frequent handovers, the LTE network adopts the method of merging cells to solve the problem, that is, several independent cells with different physical cell IDs, Merged into a logical cell with a PCI (PCI, Physical Cell Identifier), the merged logical cell is also called a super cell (SuperCell), the original independent physical cells become a part of the super cell (CP, Cell Portion ). The CP that controls the scheduling of the entire cell in the SuperCell is the cell-level primary CP, and other non-scheduling CPs are cell-level secondary CPs. [0003] In actual network coverage, Micro Cells are often placed within the coverage of Macro Cells for hotspot cov...
