Abstract: A method, a system and an apparatus can be used for transmitting data in a CA manner. A first base station currently serving a user equipment (UE), creates EPS bearers under different component carriers CC Groups for the UE. The UE sets different access stratum entities corresponding to the CC Groups to process data in the process of creating the EPS bearers. The UE determines, when transmitting or receiving data, a corresponding CC Group according to an EPS bearer that bears the data. An access stratum entity corresponding to the CC Group processes the data that needs to be transmitted or received, a site is a first base station currently serving the UE or a second base station currently serving the UE.

One example method includes determining a plurality of frequency domain units on which reporting of a precoding matrix indicator (PMI) is based in reporting bandwidth. The plurality of frequency domain units include one or more first frequency domain units and third frequency domain units obtained by dividing one or more second frequency domain units. A granularity of the first frequency domain unit is less than a preconfigured first granularity, a granularity of the second frequency domain unit is a first granularity, and a granularity of the third frequency domain unit is a predetermined second granularity. The first granularity is a granularity preconfigured for reporting a channel quality indicator (CQI), a second granularity is a granularity predetermined for reporting the PMI, and the second granularity is less than the first granularity.

Abstract: This application provides a reference signal transmission method and an apparatus, to resolve a prior-art problem of relatively high overheads of resources occupied by transmitted reference signals in a communications system. The method includes: configuring, by a transmitting device, one reference signal group corresponding to one port in the first time symbol, and configuring one reference signal corresponding to the port in each of time symbols except the first time symbol. This reduces overheads of resources occupied by transmitted reference signals in the communications system and improves service data transmission efficiency while ensuring that a receiving device can obtain a channel parameter of the port.
