Problems solved by technology

[0016] When reporting PHR according to the first method, there will be the following problems: In the Rel-10 version of the LTE standard and subsequent versions, various uplink transmission combinations are introduced, such as the uplink transmission of non-consecutive PRBs (including simultaneous transmission of PUCCH and PUSCH, Discontinuous PUSCH resource scheduling, etc.)
However, when the PRBs included in the PUSCH are discontinuous frequency resources, the MPR caused by discontinuous allocation cannot be obtained by the base station side, so that reasonable resource scheduling cannot be performed, which may easily cause system performance degradation and affect system service quality

Embodiment Construction

[0053] In order to enable the network side to know the power back-off situation of the terminal side in time, so as to perform reasonable power control. In the embodiment of the present invention, when the terminal determines that PHR reporting is triggered, if it knows that only one type of PHR is allowed to be reported according to the preset PHR reporting method, it will carry the maximum power backoff in one type of PHR selected for reporting. MRP indication, which is used to notify the network side whether the current PHR report is triggered based on the MPR exceeding the set threshold; if it is known that multiple types of PHR are allowed to be reported according to the preset PHR reporting method, then according to the preset combination rule, select At least two types of PHRs are reported in combination, where the at least two types of PHRs are obtained based on the transmission power used by the terminal when transmitting data on consecutive and discontinuous PRBs.

Abstract

The invention discloses a method, device and system for reporting PHR, which are used to realize reasonable power control of a base station to a UE. The method is as follows: for the situation where only one type of PHR is allowed to be reported, a new trigger mechanism based on MPR exceeding the set threshold is set, so that the base station can know the power backoff of the UE side in time when the MPR of the UE side is too large At the same time, for the situation where multiple types of PHRs are allowed to be reported, the types of PHRs reported are expanded, and the situation of sending data based on continuous and discontinuous PRBs is fully taken into account, so that the base station can be based on each obtained from the UE. The type of PHR can estimate the MPR of the UE during continuous scheduling and discontinuous scheduling, so that the base station can perform reasonable power control on the UE, ensuring system performance and improving system service quality. The invention also discloses a device and a system for reporting PHR.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for reporting a power margin report. Background technique [0002] At present, the LTE R10 version of the 3GPP standard has stipulated to support the discontinuous allocation of uplink frequency resource blocks (PRBs) of the terminal, for example, using the physical uplink control channel (Physical Uplink Control Channel, PUCCH) to transmit data and Data is sent using an uplink shared channel (Physical Uplink Shared Channel, PUSCH). The introduction of this mechanism will have a certain impact on the existing PHR reporting, because when the terminal (UE) uses discontinuous PRB for data transmission, due to the limitation of the out-of-band radiation index, the UE needs to adopt a certain power back-off, that is, the UE Data cannot be sent at the maximum transmit power set by itself, but a part of the power needs to be reduced. This reduction may be 4...
