Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0030] see figure 1 , a method for receiving data provided in this embodiment includes:

[0031] Step 11, the base station reserves at least two usable carriers for the terminal.

[0032] According to the channel quality of the terminal, triggering the base station (network side) to preset two or more usable carriers for the terminal includes:

[0033] (1) The terminal at the cell boundary is currently using a single carrier, but the uplink power is limited. At this time, if the terminal has a redundant power amplifier (Power Amplifier, PA) that can be used, and the newly added carrier brings The interference is acceptable to this cell and neighboring cells, then the base station will reserve at least two usable carriers for the terminal.

[0034] (2) The terminal at the ce...

Abstract

The embodiment of the invention discloses a method, device and system for sending and receiving data, which can bring coding gain and frequency diversity gain for a base station, increase the decoding accuracy, reduce the transmission delay of air interfaces, lower the packet loss ratio, improve the system performance and increase the cell coverage area when the uplink power of a terminal is limited. The method for receiving data, which is disclosed by the embodiment, comprises the following steps: sending a control signaling from the base station to the terminal, wherein the control signaling contains resource information of at least two carriers and indication for indicating the terminal to send same transmission blocks on the at least two carriers; receiving the same transmission blocks sent by the terminal on the at least two carriers; and merging and decoding the at least two same transmission blocks. The embodiment of the invention can be suitable for introducing multi-carrier long term evolution (LTE) reinforcing systems.
