Embodiment Construction

[0062] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0063] First of all, if there is no conflict, the embodiment of the present invention and the combination of various features in the embodiment on the premise of no conflict are within the protection scope of the present invention. In addition, the steps shown in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and, although a logical order is shown in the flow diagrams, in some cases, the sequence may be different. The steps shown or described are performed in the order herein.

[0064] The analysis of the prior art shows that the prior art 1 is a method with poor performance, while the problem...

Abstract

The invention discloses a sending method of control information and data, a noticing method of power information and a base station, which overcomes the defect in the prior art that the restrictions are more when second kind of control signaling and data are sent. The sending method comprises the following steps: in one or a plurality of transmission resource blocks of a down subframe, a second kind of control information belonging to a user 1 and based on demodulation of a proprietary demodulation pilot frequency port set A and data information belonging to a user 2 and based on the demodulation of a proprietary demodulation pilot frequency port set B conduct time division transmission in a subframe, wherein the proprietary demodulation pilot frequency ports contained by the proprietary demodulation pilot frequency port set A and the proprietary demodulation pilot frequency port set B are not completely same. When the embodiment of the invention sends the second kind of control signaling and data, different transmission layers and transmission power 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 (Control Channel Element, CCE) resource ...
