Embodiment 1

[0036] This embodiment provides a method for reporting an additional power backoff value. This embodiment combines the above embodiments and preferred implementation modes therein, and the method includes:

[0037] Step 1: Set up scenarios that require additional power backoff values.

[0038] Preferably, in addition to the power fallback value in general cases, additional power fallback values ​​need to be set in the following situations including but not limited to:

[0039] (1) When the inter-band CA has a diplexer device, insertion loss will occur. Because of the loss of the device itself, additional power is required to make up for it.

[0040] (2) When carrying some special signaling procedures, if the carried data is large and important, the maximum transmission power will increase, and additional power backoff is required at this time. For example, when carrying control signaling.

[0041] (3) When the spectrum mask settings are different, when the spectrum mask set...

Embodiment 2

[0047] This embodiment provides a method for reporting an additional power backoff value. This embodiment combines the above embodiments and preferred implementation modes therein. In this embodiment, in the scenario of inter-frequency carrier aggregation with a duplexer, the method includes:

[0048] Step S202: When the inter-band CA has a duplex device, the eNB (base station) sends an additional power backoff report command to the terminal through a control channel.

[0049] Step S204: Determine whether the terminal is in IDEL or CONNECTED state. If in the IDEL state, turn to step S206; if in the CONNECTED state, the UE maintains connection and information exchange with the eNB, then turn to step S212.

[0050] Step S206: UE initiates a radio resource control connection request message (RRC Connection Request).

[0051] Step S208: The eNB allocates resources in the RRC phase, and sends a radio resource control connection establishment message (RRCConnection Setup) to the UE...

Embodiment 3

[0056] This embodiment provides a method for reporting an additional power backoff value. This embodiment combines the above embodiments and the preferred implementation modes. The application scenario of this embodiment is for the UE to send a special and important signaling format, such as NS07 etc., the priority and data size of these signalings are greater than a certain threshold. The method includes:

[0057] Step 1: The eNB (base station) sends an additional power backoff report command to the terminal through a control channel.

[0058] Step 2: After receiving the report command sent by the base station, the UE reports the additional power backoff value through the same steps as steps S204-S212 in the embodiment.

[0059] It should be noted that after the special signaling is sent, the additional power backoff value is no longer reported.

Abstract

The invention discloses a method for reporting an additional power regression value and a base station as well as a terminal; the method comprises the following steps: the base station determines a current scene and needs to report the additional power regression value; and the base station sends an additional power regression reporting command to the terminal, wherein the additional power regression reporting command is used for indicating the terminal to report the additional power regression value. According to the method, the in-band noise and the out-of-band radiation reach a prescribed range under a certain scene, and the accuracy of power control of a system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for reporting an additional power backoff value, a base station and a terminal. Background technique [0002] With the development of mobile communications, Long Term Evaluation-advanced (LTE-A for short), represented by technologies such as carrier aggregation, relay (Relay), and coordinated multi-point, as an enhanced version of LTE, has gained rapid development. develop. LTE-Advanced requires a peak rate of 1Gbit / s for downlink and 500Mbit / s for uplink within a bandwidth of 100MHz. In order to work in such a wide bandwidth, LTE-Advanced introduces carrier aggregation technology. Application of carrier aggregation technology can integrate scattered spectrum resources through aggregation to obtain larger bandwidth (greater than 20MHz) and higher data rate, thus greatly promoting the development of mobile communication. Considering the backward compatibility with LTE...
