Problems solved by technology

[0003] However, the existing technology can only control the transmission power of the uplink data transmitted by the UE on the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) of the primary base station, and cannot control the UE The transmission power of the uplink data transmitted on the PUCCH or PUSCH of the secondary base station, where the different areas covered by the base station using different electromagnetic waves are called cells, the primary cell is served by the primary base station, and the secondary cell is served by the secondary base station

Embodiment 1

[0111] An embodiment of the present invention provides a transmission power control method, involving the main base station side, such as figure 1 As shown, the method may include:

[0112] S101. The primary base station determines TPC resources for the UE. The TPC resources are configured by the primary base station for the UE, or configured by the secondary base station for the UE, and the primary base station and the secondary base station simultaneously bear transmission services of the UE.

[0113] In the carrier aggregation technology, the concept of primary base station and secondary base station can be relative to a certain UE, that is, the primary base station of one UE may be the secondary base station of another UE for another UE. The secondary base station of one UE may also be the primary base station of another UE.

[0114] A macro base station and a small base station are physical concepts of a base station, wherein a macro base station is a site with relativel...

Embodiment 2

[0165] Such as Figure 5 As shown, the embodiment of the present invention provides a base station 1, corresponding to a transmission power control method provided in the embodiment of the present invention, the base station 1 may include:

[0166] The determining unit 10 is configured to determine a TPC resource for the UE, the TPC resource is configured by the base station for the UE, or configured by a secondary base station for the UE, and the base station and the secondary base station simultaneously bear The transmission service of the UE.

[0167] The sending unit 11 is configured to send the TPC resource and the TPC used to adjust the transmission power of the UE's PUCCH in the secondary cell to the UE, so that the UE identifies the TPC according to the TPC resource, and according to The TPC adjusts the transmission power, and the secondary cell is a cell served by the secondary base station.

[0168] Optionally, the TPC resource determined by the determining unit 10...

Embodiment 3

[0210] Such as Figure 11 As shown, the embodiment of the present invention provides a base station, corresponding to a transmission power control method provided in the embodiment of the present invention, the base station may include a transmitter 40, a receiver 41, a processor 42, and a memory 43, wherein,

[0211] The transmitter 40 can be used to send downlink signals to the UE. In particular, if the base station needs to communicate with the UE, the transmitter 40 can send downlink data to the UE.

[0212] The receiver 41 can be used to receive uplink signals from the UE, especially, if the UE needs to communicate with the base station, the receiver 41 can receive uplink data from the UE.

[0213] The processor 42 is the control and processing center of the base station. By running the software program stored in the memory 43, calling and processing the data stored in the memory 43, the base station is controlled to send and receive signals, and realize other functions o...

Abstract

The invention provides a control method and a device of transmission power, and relates to the communication field. After MSA is led in, a main base station is capable of effectively controlling transmission power of UE on PUCCH of an auxiliary area. The method comprises that the main base station determines transmission power control TPC resources used for the UE. The TPC resources are disposed for the UE by the main base station or by the auxiliary base station. Both the main base station and the auxiliary base station carry the transmission servie of the UCE. The main base station sends the TPC resources and the TPC adjusting the transmission power of the UE on the PUCCH of the axuliary area for the UE so as to allow the UE to identify the TPC according to the TPC resoureces and adjust the transmission power according to the TPC. The auxiliary area is an area for which the auxiliary base station provides services.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission power control method and device. Background technique [0002] With the development of mobile communication technology and the increase of the number of people using mobile data services, the load of existing macro cells is getting heavier and heavier. In order to provide users with better services, 3GPP (the 3rd Generation Partnership Project, the third generation partner Project) introduces carrier aggregation technology, that is, the primary base station and the secondary base station can jointly provide services for UE (User Equipment, user equipment), thereby realizing high-speed data transmission. [0003] However, the existing technology can only control the transmission power of the uplink data transmitted by the UE on the PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shar...
