Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and apparatus of adjusting the expectation received signal to noise ratio of terminal.
Background technology
LTE(Long Term Evolution, Long Term Evolution) adaptive-bandwidth of system, can be based on PSD(Power Spectral Density, power spectral density) carries out power control, total transmitted power of system can be changed along with the variation of bandwidth, thereby realize MCS(Modulation and Coding Scheme, Modulation and Coding Scheme), the coupling between bandwidth and the total transmitted power.
The LTE system adopts open loop to carry out uplink power control in conjunction with the pattern of closed loop, and terminal is determined the open loop parameter based on self to the understanding and the resource allocation result of channel, that is, i subframe is the bandwidth that PUSCH distributes

P CMAXBe the maximum transmission power that terminal allows,
α (j) PLBe that the path loss in the transmission course is compensated.
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:
The PUSCH expectation received signal to noise ratio of cell-level is based on the throughput of system maximum and turns to the cell-level parameter that prerequisite emulation draws, and system emulation scene and terminal actual transmissions scene can be different, therefore, the PUSCH expectation received signal to noise ratio signal to noise ratio different situation required with the terminal transmission current business that cell-level can occur makes the uplink quality of service of terminal after closed power control can't reach the expectation requirement.
Particularly, when the PUSCH of cell-level expectation received signal to noise ratio is lower than the required signal to noise ratio of terminal transmission current business, the adjusted terminal PUSCH received signal to noise ratio of closed-loop power control will be expected received signal to noise ratio near cell-level, and be lower than the required signal to noise ratio of terminal transmission current business, cause up appearance to influence the Block Error Rate of quality of service, and the base station can't adjust again, makes service transmission quality further worsen.When the PUSCH of cell-level expectation received signal to noise ratio is higher than the required signal to noise ratio of terminal transmission current business, the adjusted terminal PUSCH received signal to noise ratio of closed-loop power control will be expected received signal to noise ratio near cell-level, and be higher than the required signal to noise ratio of terminal transmission current business, wasted transmitting power, also can cause interference adjacent sub-district.
