Problems solved by technology
When the data transmission quality of a terminal device on a subband is poor, the base station cannot blindly switch the terminal device to other subbands because there is no information about the terminal device on other subbands, thus affecting the data transmission quality of the terminal device speed
[0004] Or, when the base station needs to have a certain flexibility to clear a certain subband, because there is no information about the terminal equipment on other subbands, the base station cannot determine which subband to switch the communication between the terminal equipment and the base station to, thereby providing Certain limitations caused by some operations

Embodiment Construction
[0053] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.
[0054] figure 1 It is a schematic diagram of a communication system provided by an embodiment of the present invention. Such as figure 1 As shown, the system architecture may specifically include: an access network device 101 and multiple terminal devices 102 (User Equipment, UE for short). Wherein, the access network device 101 can communicate with multiple terminal devices 102 . Wherein, the communication between the access network device 101 and the plurality of terminal devices 102 is through channel transmission. The channel can be further divided into multiple subbands, and the communication between the access network device 101 and any terminal device 102 is performed in one subband.
[0055] Specific embodiments of the present invention provide a method and device for measuring reference signal data. ...

Embodiments of the present invention disclose a reference signal sending method and apparatus and a reference signal receiving method and apparatus. In a channel state information receiving method, a base station sends first signaling to a terminal device. The first signaling includes channel state information-reference signal CSI-RS information of each of a plurality of subbands. The base station sends a CSI-RS in at least one of the plurality of subbands. The base station receives channel state information sent by the terminal device, where the channel state information is obtained by measuring the CSI-RS sent in the at least one subband. The embodiments of the present invention provide a reference signal data sending method and apparatus and a reference signal data receiving method and apparatus. A plurality of subbands may be configured for one terminal device, to simultaneously obtain reference signals of the plurality of subbands, so that a base station can switch, based on a result of the reference signals, a subband used by the terminal, thereby maintaining flexibility of a base station side and maximizing data transmission of the terminal device.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for measuring a reference signal. Background technique [0002] A channel state information reference signal (English: Channel State Information-Reference Signal, CSI-RS) and a sounding reference signal (English: Sounding Reference Signal, SRS) are collectively referred to as a reference signal. The reference signal is used to detect channel information to determine the communication quality of the channel. The existing LTE reference signals are basically distributed in the entire system bandwidth. Considering the requirements of forward compatibility, NR or 5G, the bandwidth of reference signals (such as CSI-RS, SRS) should be configurable, in a In the configuration scheme, a subband is individually configured for each user. However, in this way, the communication between the terminal equipment and the base station can only be transmitted on ...
