    Abstract: The present disclosure relates to example data transmission methods, user equipment, and access network devices in an LAA-LTE system. An example data receiving method includes determining, by user equipment, first information of a first cell. The user equipment determines a first subframe based on the first information, where a downlink data transmission length of the first subframe is less than a first threshold. The user equipment then determines a data transmission characteristic of the cell in the first subframe based on a preset condition, so as to receive, based on the data transmission characteristic, data including the first subframe. In doing so, a data transmission characteristic of a base station or a terminal is standardized, and a reference signal such as a DRS can be correctly identified.

    Abstract: Embodiments of the present invention provide a method for transmitting a pilot signal, a method for receiving a pilot signal, a user equipment (UE), and a base station. A method includes: determining a first downlink subframe according to an uplink and downlink ratio relationship, where the first downlink subframe is a first downlink subframe after a transition from uplink to downlink; transmitting a pilot signal to a UE in the first downlink subframe. Another method includes: determining, according to a preset transmit period and a subframe offset number, a second downlink subframe for transmitting a pilot signal, and transmitting the pilot signal to a UE in the second downlink subframe. According to the technical solution of the present invention, time domain resources occupied by a pilot signal are reduced, therefore, the overhead of transmitting the pilot signal is reduced.

    Abstract: A method and an apparatus for implementing channel measurement are disclosed in the present invention. The method includes: determining an antenna port subset, which is required to be measured, for a UE according to current state information of the user equipment UE; and informing the UE to perform channel measurement for the subset of antenna ports that is required to be measured and feed back channel state information. Through the present invention, when the state information of the UE meets a certain condition, the UE measures only the reference signals of a part of antenna ports, and feeds back channel state information for this part of antenna ports. Therefore, the overhead generated by the feedback of the UE to the channel state information is reduced.
