Embodiment Construction

[0027] In the LTE system, PHR related technologies include:

[0028] (1) RRC (Radio Resource Control, radio resource control) layer parameter configuration related to the PHR. The purpose of the PHR report is to inform the eNB (base station) of the difference between the maximum transmit power of the UE and the UL-SCH (UL-Shared Channel, uplink shared channel) channel transmit power estimated by the UE. PHR reporting parameters are configured by the RRC layer, and related parameters include: timer parameters, period of periodic PHR reporting timer periodicPHR-Timer, length of prohibiting PHR reporting timer prohibitPHR-Timer, triggering PHR reporting path loss change parameter dl- PathlossChange, such as figure 1 The schematic diagram of the related configuration of the RRC layer PHR is shown.

[0029] (2) The trigger mechanism of PHR. Among them, PHR can be triggered when one of the following conditions is met:

[0030] The UE has uplink resources available, the prohibitP...

Abstract

The invention discloses a method and equipment for processing a PHR (Protocol Data Unit) in a carrier aggregation system. The method for processing the PHR comprises the steps: user equipment is used for obtaining path damage change corresponding to the current uplink carrier in an activated state; the user equipment judges whether to trigger the PHR according to the path damage change; and if so, the user equipment obtains the PH (Protocol Data) information of power allowance needing to be reported and reports the PH information. In the embodiment of the invention, UE (user equipment) can trigger the PHR according to the path damage change of the current uplink carrier in the activated state in the carrier aggregation system.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and equipment for processing PHR in a carrier aggregation system. Background technique [0002] (1) CA (Carrier Aggregation, carrier aggregation) [0003] The peak rate of the LTE-A (LTE-Advanced, Advanced LTE) system has been greatly improved compared with the LTE (Long Term Evolution, Long Term Evolution) system, and it is required to reach 1Gbps downlink and 500Mbps uplink. Very good compatibility. [0004] Based on the need to increase the peak rate, be compatible with the LTE system, and make full use of spectrum resources, the LTE-A system introduces carrier aggregation technology. Wherein, the carrier aggregation technology refers to including multiple CCs (component carriers, component carriers) in the uplink and downlink in a cell. [0005] Specifically, in a carrier aggregation system, component carriers may be contiguous or non-contiguo...
