Abstract

The invention discloses a method for sending control information and data, a method for notifying power information and a base station, which overcomes the defect that there are many limitations in sending the second type of control signaling and data in the prior art. The sending method includes: In one or more transmission resource blocks of the downlink subframe, the second type of control information that belongs to user 1 and is demodulated based on the dedicated demodulation pilot port set A and belongs to user 2 and is demodulated based on the dedicated demodulation pilot port set B The demodulated data information is time-divisionally transmitted in one subframe, and the dedicated demodulation pilot ports contained in the dedicated demodulation pilot port set A and the dedicated demodulation pilot port set B are not exactly the same. Implementation of the present invention For example, when sending the second type of control signaling and data, different transmission layers and transmission powers can be selected.

Description

technical field [0001] The invention relates to the communication field, and relates to a method for sending downlink control information and data in a communication system, a method for notifying power information, and a base station. Background technique [0002] In the Long term evolution (LTE for short) system version (Release, R for short) 8 / 9 and the LTE-Adavance system version R10, the downlink control signaling is generally configured to be sent on the first N OFDM symbols, generally called These N symbols are control signaling transmission areas. In order to distinguish it from the newly added control signaling transmission area of ​​the new version, the control signaling transmission area of ​​R8 / 9 / 10 is called the first control signaling transmission area in the present invention. [0003] The available transmission resources in the first control signaling transmission area are divided into multiple control channel element (ControlChannel Element, CCE) resource u...
