Currently, there is no way for the eNB to know this information, and considering that only ranges / tables are defined in 3GPP TS36.101 as mentioned earlier, it is not feasible to guess which part of the power reduction is taken into account in Pcmax,c

Embodiment Construction

[0073] Exemplary embodiments describe indicating to a radio base station, e.g. C In addition to conventional power backoff, additional power backoff has been done in the UE in order to eg meet the SAR requirement and has affected the actual transmit power of the UL CC utilized by the UE in different ways. This transmit power (Pcmax,c) may be reported per CC to the eNB as part of the power headroom report.

[0074] It should be noted that the type of power backoff indicated according to one or several exemplary embodiments may be any type of additional power backoff. The embodiments in no way limit the type or reason for power management to be considered "normal" or "other". Thus, it allows the radio base station to distinguish at least two types of power backoff in the network and decide how to use the reported value (power headroom and / or Pcmax,c) based on the indication.

[0075] Examples of applicable exemplary methods are indicating power backoff due to SAR requirements ...

Abstract

The exemplary embodiments describe a method for use in a user equipment (700), a method for use in a radio base station (600); a user equipment (700) and a radio base station (600). According to the exemplary embodiments, the user equipment (700) is configured to decide on application or not of a power reduction and to indicate it decision in a power headroom report intended for transmission to the radio base station (600). The radio base station (600) is configured to receive the power headroom report and based on the indicated information in the received power headroom report, the base station in made aware of an additional or special power backoff (e.g. to fulfill SAR requirements) has been applied and thereby able to distinguish it from normal power backoff or power reduction.

Description

[0001] This application is a divisional application of the application dated April 29, 2011, the application number is 2011800632913, and the title of the invention is "Method and device for allowing power back-off indication in PHR in a telecommunication system". technical field [0002] The presently described embodiments relate generally to the field of wireless telecommunications, and more particularly to methods and apparatus for allowing power backoff indication in at least a Power Headroom Report (PHR) in a communication system. Background technique [0003] In telecommunication systems such as LTE (Long Term Evolution), OFDM (Orthogonal Frequency Division Multiplexing) is used in the downlink, and DFT (Discrete Fourier Transform) extends OFDM (also known as Single Carrier Frequency Division Multiple Access SC-FDMA ) are used in the uplink. Basic LTE downlink physical resources can thus be viewed as figure 1 In the time-frequency grid shown, each resource element in ...
