Embodiment approach

[0278] This embodiment provides an implementation manner in which the Macro reduces the power of the Macro on the first carrier layer according to the maximum path loss or the minimum RSRP or the minimum SINR. The implementation manner includes:

[0279] Step 4021, Macro sets the upper limit of the power of the Macro on the first carrier layer to the power of the Macro on the second carrier layer, and sets the lower limit of the power of the Macro on the first carrier layer to the value of each LPN on the first carrier layer or the power on the second carrier layer, or set the lower limit of Macro power on the first carrier layer to 0. Wherein, if the resource utilization rate of the Macro on the first carrier layer is lower than a certain value within a certain period of time, the power of the Macro on the first carrier layer may be 0.

[0280] Step 4022, Macro performs power class division according to the upper power limit and lower power limit of the Macro on the first car...

Abstract

The present invention provides a communication method, device and system. The method comprises: a macro station (Macro) acquiring uplink measurement information thereof and of a first low power node (LPN) or downlink measurement information fed back by a user equipment (UE), or acquiring uplink measurement information and downlink measurement information; the Macro performing bias processing on the uplink measurement information thereof and of the first LPN and / or the downlink measurement information fed back by the UE respectively; the Macro selecting, according to a bias processing result, the first LPN or Macro as a network attachment point of a first UE, so that the first UE performs communications through the network attachment point. The technical solution of the present invention is capable of enhancing the split gain of the cell or area of an LPN in the scenarios having the same or different cell identifiers (cell IDs).

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a communication method, device and system. Background technique [0002] At present, 3GPP is discussing scenarios of different cell IDs (cell IDs) and the same cell ID in a heterogeneous network (Heterogeneous Network, HetNet). The scenario of different cell ID refers to the low power node (Low Power Node, LPN) under the coverage of the macro station (Macro) in HetNet, such as the remote radio head (Remote Radio Head, RRH), the transmission or reception point generated by the A scenario in which macro cells have different cell IDs to form independent cells. That is to say, in different cell ID scenarios, the cell ID of the LPN is different from the cell ID of the Macro. The same cell ID scenario refers to the scenario in which in the HetNet, the sending or receiving point generated by the LPN under the control of the Macro has the same cell ID as the macro cell, thus b...
