Abstract:
Embodiments of the present application provide a method, a terminal, and a base station for transmitting information. In the embodiments of the present application, subframe configuration information of a first carrier is obtained, where the subframe configuration information is used to indicate a type-1 subframe of the first carrier and a type-2 subframe of the first carrier, the type-1 subframe is used for the base station to transmit, in system bandwidth, first information including a first CRS, the first CRS is used for demodulation, and the type-2 subframe is not used for the base station to transmit a CRS used for demodulation, so that the terminal can receive, according to the subframe configuration information and on the first carrier, information sent by the base station.
Abstract:
The present invention discloses a method and a system for data demodulation, and a user equipment. An interference statistic characteristic is measured by using an IMR instead of a CRS or a non-zero power CSI-RS, so that the obtained interference statistic characteristic can truly reflect an interference statistic characteristic that a DMRS actually experiences, and then a PDSCH is demodulated, so as to improve accuracy of channel estimation.
Abstract:
A signal transmission method and apparatus are provided. The method includes generating a first signal according to at least one protocol layer of a first protocol stack and a second protocol stack, and sending the first signal to a receive end by using a first uplink carrier; and/or receiving, by using a first downlink carrier, a third signal sent by receive end, and parsing the third signal according to the at least one protocol layer of the first protocol stack and the second protocol stack; where the first protocol stack is used to implement communication between a base station and a user equipment on a base station side, the second protocol stack is used to implement communication between devices, and the second protocol stack is connected to the at least one protocol layer of the first protocol stack. Therefore, signal transmission can be implemented by using uplink and downlink carriers.
