Embodiment 1

[0070]In this embodiment, a method of signaling the base station to inform the UE of the power ratio of the ABS subframe to the non-ABS subframe is provided for the UE to perform data demodulation. Refer to Figure 5 As shown, the process includes the following steps:

[0071] Step 1, the base station sends the signaling b1b2b3=010 to the UE through the RRC Connection Reconfiguration signaling. Table 1 is the correspondence table of signaling and power ratio. As shown in Table 1, the above signaling indicates that the UE is in the ABS subframe and the non-ABS The subframe PDSCH EPRE ratio is 1 / 3.

Abstract

The invention discloses a method and a device for processing power parameters. The method comprises the following steps: user equipment (UE) acquires the power relationship parameter and the ratio of a first kind of sub-frames and a second kind of sub-frames, wherein the power relationship parameter is used for indicating the power relationship of the first kind of sub-frames and the second kind of sub-frames; and the UE performs data demodulation operation and / or channel measurement operation on the first kind of sub-frames by utilizing the power relationship parameter and the ratio. Through the method and the device provided by the invention, the problem that the data demodulation or channel measurement of the UE is inaccurate due to different power configurations of different kinds of sub-frames in correlation techniques is solved, and the system performance is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing power parameters. Background technique [0002] Statistics show that in the future 80% to 90% of system throughput will occur in indoor and hotspot scenarios. However, the traditional cellular network technology has the characteristics of "emphasis on outdoor, less on indoor", "emphasis on cellular networking, less on isolated hotspots", "emphasis on mobile switching, less on fixed nomadic" and so on. One of the key points of work of the advanced long-term evolution system (Long-Term Evolution Advance, referred to as LTE-Advance) is to optimize indoor and hotspot scenarios. Heterogeneous Networks (Heterogeneous Networks), as a technology that significantly increases system throughput and improves overall network efficiency, can well meet the requirements of LTE Advance. The heterogeneous network structure introduces some transmitting nodes w...
