Embodiment 1

[0045] see image 3, which shows a method for configuring transmission parameters provided by an embodiment of the present invention. This method can be applied to network devices in device-to-device D2D, and can even be applied to network devices in V2X technology. Specifically, it can be the A base station, the method comprising:

[0046] S301: Configuring the transmission parameters used for sidelink SL transmission for the target terminal;

[0047] S302: Send the transmission parameter to the target terminal; wherein the transmission parameter is used for the target terminal to perform SL transmission based on the configuration of the transmission parameter.

[0048] In the method for configuring transmission parameters provided in this embodiment, the network device configures the transmission parameters used for sidelink transmission for the target terminal, and sends the transmission parameters to the target terminal through configuration information. Compared with th...

example 1

[0064] In this example, the sending the transmission parameter to the target terminal includes:

[0065] The transmission parameters are carried in downlink control information DCI, and sent to the target terminal through a physical downlink control channel PDCCH.

[0066] Specifically, carrying the transmission parameters in the downlink control information DCI includes:

[0067] Indicating the transmission parameters through information bits in the DCI; or,

[0068] The transmission parameter is carried by a scrambling code sequence that performs a scrambling code operation on the DCI; or,

[0069] The transmission parameter is carried by a mask sequence that performs a masking operation on the DCI.

[0070] Understandably, the network device may additionally set an information bit field in the DCI to directly and explicitly indicate the transmission parameter. In addition, in order to avoid changes in the structure of the DCI field, the transmission parameters can also b...

example 2

[0072] In this example, the sending the transmission parameter to the target terminal includes:

[0073] The transmission parameters are carried in a demodulation reference signal (DMRS, DeModulationReference Signal) of a downlink control channel PDCCH, and sent to the target terminal through the PDCCH.

[0074] Specifically, carrying the transmission parameters in the demodulation reference signal DMRS of the downlink control channel PDCCH includes:

[0075] The transmission parameters are carried in the root sequence, and / or cyclic shift, and / or Orthogonal Cover Code (OCC, Orthogonal Cover Code) of the demodulation reference signal DMRS of the PDCCH.

[0076] For the first example, the DCI sent by the PDCCH is used to carry the transmission parameters, but in this example, the DMRS of the PDCCH can be used to send the transmission parameters. Specifically, the transmission parameter may be carried in the root sequence of the demodulation reference signal DMRS of the PDCCH, ...

Abstract

Provided are a method and device for configuring transmission parameters, and a computer storage medium. The method comprises: configuring, for a target terminal, transmission parameters used during sidelink (SL) transmission; and sending the transmission parameters to the target terminal, wherein the transmission parameters are used for the target terminal to carry out SL transmission based on the configuration of the transmission parameters. Compared with a base station merely configuring, for a terminal, a time-frequency resource for data transmission in the current related V2X technology, by configuring transmission parameters used for a target terminal to carry out SL transmission, the failure in data transmission caused during transmission between incompatible terminals by means of an SL can be avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method, device and computer storage medium for configuring transmission parameters. Background technique [0002] The Internet of Vehicles system adopts the long-term evolution (LTE, Long Term Evolution)-device-to-device (D2D, Device to Device) sidelink (SL, Sidelink) transmission technology, and the communication data in the traditional LTE system is received through the base station or The transmission method is different. In the Internet of Vehicles system, terminals communicate directly through the PC5 interface (interface between terminals), that is, the sidelink SL, which has higher spectral efficiency and lower transmission delay. [0003] In the 3rd Generation Partnership Project (3GPP, the 3rd Generation Partnership Project) Rel-14, the vehicle networking technology (V2X, Vehicle-to-Everything) is standardized, and two trans...
