Embodiment 1

[0034] An embodiment of the present invention provides a signal transmission method, which is applied to a base station, such as figure 2 As shown, the method includes:

[0035] Step 201: Select a downlink transmission frame, and determine a first guard period (GP, GuardPeriod) in the downlink transmission frame;

[0036] Step 202: setting at least one downlink signal in the first GP;

[0037] Step 203: Send the downlink transmission frame to the terminal device.

[0038] The basic idea of ​​this proposal is to specially design these interference-free resources for GP1 in the downlink transmission frame and GP2 in the uplink transmission frame. Specifically, it may be considered to prioritize setting downlink control signals on GP1, such as downlink demodulation reference signal (DMRS, Demodulation Reference Signal), CSI-RS, non-orthogonal signal transmission that is sensitive to interference, etc. Signals sensitive to interference, such as uplink DMRS, uplink control sign...

Embodiment 2

[0070] The embodiment of the present invention provides a signal transmission method, which is applied to terminal equipment, such as Figure 4 As shown, the method includes:

[0071] Step 401: receiving a downlink transmission frame from the base station;

[0072] Step 402: Analyzing and obtaining at least one downlink control signal from the first GP of the downlink transmission frame;

[0073] Step 403: Perform processing based on the at least one downlink control signal obtained through analysis.

[0074] On the basis of the above processing flow, this embodiment further focuses on how the terminal device performs subsequent processing based on the received downlink transmission frame:

[0075] The analyzing and obtaining at least one downlink signal from the first GP of the downlink transmission frame includes:

[0076] Based on the cell wireless network temporary identifier, analyze and obtain the resource indication field of the uplink control signal from the first G...

Embodiment 3

[0106] An embodiment of the present invention provides a base station, such as Figure 5 As shown, the base station includes:

[0107] The first processing unit 51 is configured to select a downlink transmission frame, and determine a first protection period GP in the downlink transmission frame;

[0108] A setting unit 52, configured to set at least one downlink signal in the first GP;

[0109] The first sending unit 53 is configured to send the downlink transmission frame to the receiving end.

[0110] The basic idea of ​​this proposal is to specially design these interference-free resources for GP1 in the downlink transmission frame and GP2 in the uplink transmission frame. Specifically, it may be considered to prioritize setting downlink control signals on GP1, such as downlink demodulation reference signal (DMRS, Demodulation Reference Signal), CSI-RS, non-orthogonal signal transmission that is sensitive to interference, etc. Signals sensitive to interference, such as ...

Abstract

The invention discloses a signal transmission method, base station, terminal equipment and system, wherein the method includes: selecting a downlink transmission frame, determining a first protection period GP in the downlink transmission frame; setting at least one protection period in the first GP A downlink signal; sending the downlink transmission frame to the terminal device.

Description

technical field [0001] The present invention relates to transmission management technology in the communication field, and in particular to a signal transmission method, base station, terminal equipment and system. Background technique [0002] 3GPP has made it clear that it will start the standardization of 5G in 2016, and initially plans to submit technical solutions for three typical 5G scenarios to the ITU in 2019. In order to effectively address the needs of 5G business diversity, some companies in the industry currently propose a frame structure (Self_contain: self-contained), as follows figure 1 As shown, that is, both uplink and downlink controls are included in one TTI, and the data part can be flexibly uplink data or downlink data. figure 1 The frame structure shown can effectively meet the needs of low-latency and long-latency services in the future through the dynamic transmission time interval (TTI); through the transmission of ACK / NACK on the uplink control re...
