摘要： Provided are an architecture, method and apparatus for realizing communication between network functions, including: an interface function registering with an interface function management module after being instantiated, so that the interface function management module stores information corresponding to the interface function; and network functions in a same communication domain directly interworking with each other to realize communication, and the network function establishing communication with the network function in another communication domain via the interface function. An interworking interface between the network function and a selected interface function which is in the same communication domain with the network function is identical to an interworking interface between the network function and a destination network function which is in the same communication domain with the network function. With the architecture for realizing communication between network functions provided by the embodiments, the network function and the interface function are decoupled. The network function can realize the interworking with the network function inside the communication domain as well as the interworking with a destination network function outside the communication domain by only one type of interworking interface, so that the logic of the network functions becomes simple, thereby simplifying the design of the network functions and greatly reducing the development and deployment difficulties of the network functions.

摘要： Provided are a method for channel information feedback in a multi-antenna system, and a terminal. The method comprises: a terminal receives CSI-RSs of M ports sent by a base station, and performs estimation according to the CSI-RSs to obtain M-dimensional downlink channel information; the terminal uses a transformation function F k to perform a linear transformation on the M-dimensional downlink channel information, and obtains N k -dimensional kth type channels, wherein k is greater than or equal to 1 and less than or equal to K, M ≥ N k , and K ≥ 1; the terminal uses a preset N k -dimensional codebook to respectively perform channel information quantisation on the k th type channels, and determines a corresponding precoding matrix and precoding matrix indicator information (PMI k ); the terminal selects S type channels from within K type channels, and feeds index numbers of the selected channels and corresponding PMI back to the base station.

摘要： Provided are a pilot signal transmission method and apparatus, and a transmitting terminal. The method includes: setting a first pilot signal, a second pilot signal, and a third pilot signal on a same subcarrier; and transmitting the first pilot signal, the second pilot signal, and the third pilot signal respectively on three continuous symbols on the same subcarrier. The first pilot signal, the second pilot signal, and the third pilot signal are all nonzero data, a phase difference between the first pilot signal and the second pilot signal is 90 degrees, a phase difference between the third pilot signal and the second pilot signal is 90 degrees, and a phase difference between the first pilot signal and the third pilot signal is 180 degrees. The technical solution saves resources for interference separation and pilot overhead, and improves the channel estimation performance of a receiving terminal by means of interference cancellation, so as to improve the channel estimation performance of a FBMC system or other systems using time frequency resources as physical resources in a case where the pilot overhead is low.

摘要： Provided is a method for sending a V2X service. The method includes: a Vehicle-to-Everything (V2X) Application Server (AS) classifies and identifies the V2X service, where different types of V2X service have different identifiers; the V2X AS sends a request message to a Broadcast Multicast Service Center (BM-SC), where the request message is used for instructing the BM-SC to establish a Multimedia Broadcast Multicast Service (MBMS) bearing corresponding to an identifier of theV2X service; and the V2X AS sends the V2X service through the MBMS bearing established by the BM-SC. The above solution addresses the problem that it is difficult for the V2X AS to forward different types of V2X services in the related art.
