Embodiment 1

[0133] An embodiment of the present invention provides a signal receiving method, such as figure 1 As shown, the method may include:

[0134] S101. Acquire at least one narrowband through first signaling, where the first signaling is used to determine a position of the at least one narrowband.

[0135]The embodiment of the present invention is described by taking the signal receiving device as a terminal as an example.

[0136] An embodiment of the present invention is a process in which a terminal receives a signal related to positioning, that is, a first reference signal, through at least one narrowband.

[0137] Specifically, the terminal may determine the location of at least one available narrowband, that is, information about a center frequency point of the at least one narrowband, through the first signaling sent by the network side device.

[0138] Optionally, in this embodiment of the present invention, the first reference signal includes at least one of a narrowban...

Embodiment 2

[0180] Based on Embodiment 1, when the first reference signal is a narrowband positioning reference signal, a signal receiving method provided by the embodiment of the present invention is as follows: Figure 6 As shown, the method may include:

[0181] S201. Acquire at least one narrowband through first signaling, where the first signaling is used to determine a position of the at least one narrowband.

[0182] It should be noted that, the process of the terminal acquiring at least one narrowband through the first signaling in S201 is consistent with the description of S101 in Embodiment 1, and will not be repeated here.

[0183] S202. Detect whether the narrowband positioning reference signal conflicts with the reception of the physical downlink channel signal.

[0184] S203. When it is detected that the physical downlink channel signal collides with the narrowband positioning reference signal in the first subframe received on one of the at least one narrowband, give up rec...

Embodiment 3

[0252] Such as Figure 12 As shown, the embodiment of the present invention provides a signal receiving device 1, the signal receiving device 1 may include:

[0253] The acquiring unit 10 is configured to acquire at least one narrowband through first signaling, and the first signaling is used to determine the position of the at least one narrowband.

[0254] The receiving unit 11 is configured to sequentially receive a first reference signal on the at least one narrowband starting from a preset time, where the first reference signal is a signal used for positioning.

[0255] The measuring unit 12 is configured to perform a first measurement according to the first reference signal.

[0256] Optionally, the first reference signal includes at least one of a narrowband reference signal, a narrowband primary and secondary synchronization signal, and a narrowband positioning reference signal.

[0257] Optionally, the receiving unit 11 is specifically configured to sequentially rec...

Description

technical field [0001] The present invention relates to data transmission technology in the communication field, in particular to a signal receiving method, device and terminal. Background technique [0002] In order to meet the requirements of Cellular Internet of Things (C-IoT, Cellular Internet of Things), a new access system named Narrowband Internet of Things (NB-IoT, NarrowBand-Cellular Internet of Things) is designed in the 3rd Generation Partnership Project (3GPP , 3rd Generation Partnership Project) was proposed in the 69th plenary session of the organization. Among them, the NB-IoT system focuses on low-complexity and low-throughput radio access technologies. Its main research goals include: improved indoor coverage, support for a large number of low-throughput user equipment, low delay sensitivity, Low equipment cost, low equipment power consumption and network architecture. The transmission bandwidth of the uplink and downlink of the NB-IoT system is 180kHz, wh...
