REFERENCE SIGNAL TRANSMITTING METHOD, RECEIVING METHOD AND DEVICE
FIG8 is a schematic structural diagram of different antenna panel patterns according to an embodiment of this application  FIG7 is a schematic structural diagram of an apparatus for receiving a reference signal according to an embodiment of this application
The antenna panel information includes at least one of a distribution structure of all antennas of the UE and a panel pattern (panel pattern), or other information. Herein the panel pattern information further includes at least one of a quantity of panels and a distribution pattern of P (P≥1) panels, or other information. The distribution pattern information of the panels may be a plurality of panel distribution patterns predefined on the base station and the user side. For example, FIG8 is a schematic structural diagram of four antenna panel patterns, where × represents a pair of reference signal antenna ports in two polarization directions, different reference signal antenna ports are distributed in different positions of the terminal device, and different antenna port panel patterns are generated. As shown in FIG8, a distance between a port number 1 and a port number 2 in an antenna port panel pattern 2 (pattern 2) on a UE side is a large antenna distance (codebook configuration applicable to a large antenna distance), but a distance between a port number 1 and a port number 2 in a panel pattern 3 (pattern 3) is a small antenna distance (codebook configuration applicable to a small antenna distance). Therefore, codebook configurations corresponding to the antenna port panel pattern 2 and panel pattern 3 are different. The method provided by this embodiment is used to configure an optimal codebook for antenna ports in each panel pattern, for transmitting an uplink signal, so that uplink data transmission performance can be improved.  In addition, this embodiment further provides an apparatus for receiving a reference signal. The apparatus is configured to implement the method for receiving a reference signal in the foregoing embodiment. The apparatus is disposed in a first network device, for example, a base station. As shown in FIG7, the apparatus for receiving a reference signal includes a receiving unit 701, a processing unit 702, and a transmission unit 703. In addition, the apparatus may further include other functional units or modules such as a storage unit.
