Embodiment Construction

[0072] The existing PHR reporting mechanism cannot reflect the power backoff situation of the UE, so the base station does not know the power backoff situation of the UE, and therefore cannot perform reasonable power control on the UE.

[0073] The embodiment of the present invention provides a method for reporting the maximum power backoff MPR value. The UE can report the MPR values ​​of each group of discontinuous scheduling modes to the network side equipment, so that the network side equipment can consider The MPR value of the UE, and then perform reasonable power control on the UE. The network side device in the embodiment of the present invention is generally a base station.

[0074] In the embodiment of the present invention, it is necessary for the network side device to group the discontinuous scheduling modes in advance, and send each group of discontinuous scheduling modes to the UE, or the network side device and the UE negotiate to determine the grouping mode of th...

Abstract

The invention relates to the field of mobile communications, and in particular relates to methods and devices for reporting max power reduction (MPR) values and controlling user equipment (UE) power. By adopting the methods, UE can report the MPR values in the discontinuous scheduling mode to network side equipment and the network side equipment can reasonably control the UE power according to the MPR values of the UE during discontinuous scheduling. The method for reporting the MPR value comprises the following steps that: the UE determines the MPR value corresponding to each discontinuous physical resource block (PRB) scheduling mode; and when discontinuous PRB scheduling is carried out on the UE, the UE reports the determined MPR values to the network side equipment so that the network side equipment controls the UE power according to the MPR values corresponding to the discontinuous PRB scheduling modes when the UE is scheduled.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for reporting an MPR value and controlling UE power. Background technique [0002] At present, the LTE R10 version has planned to support discontinuous allocation of uplink PRB (Physical Resource Block, Physical Resource Block) of UE (User Equipment, user equipment), including sending PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Control Channel) and PUSCH ( physical uplink shared channel). The introduction of this mechanism will have a certain impact on the existing PHR (Power headroom report, power headroom report) report. When the UE uses discontinuous PRBs to transmit, due to the limitation of the out-of-band radiation index, the terminal needs to adopt a certain power back-off. It is 4-6db or even more, and the power backoff conditions of different UEs are also different. [0003] Figure 1A It is a schematic diagram of the UE...
