Description

Processing method, intelligent terminal and storage medium

Technical field

This application relates to the field of communication technology, and specifically to a processing method, an intelligent terminal and a storage medium.

Background technique

In some implementations, the S-SS (Sidelink Synchronization Signal, side link synchronization information)/PSBCH (Physical Sidelink Broadcast Channel, physical broadcast channel) block is mapped to 11 consecutive physical resource blocks, but on the unlicensed spectrum, Regulatory regulations stipulate that each transmission must occupy at least 80% of the bandwidth in the frequency domain, that is, OCB (Occupied Channel Bandwidth, occupied channel bandwidth) requirements. The bandwidth of the carrier on the unlicensed spectrum is 20MHz, corresponding to 15kHz SCS (Sub-Carrier) Spacing, subcarrier spacing) is 106 physical resource blocks, and 30kHz SCS is 51 physical resource blocks.

Based on the above-mentioned mobile terminal hardware structure and/or communication network system, various embodiments of the present application are proposed.

In some implementations, the side-link synchronization information block is mapped to 11 consecutive physical resource blocks. However, on unlicensed spectrum, regulatory regulations stipulate that each transmission needs to occupy at least 80% of the bandwidth in the frequency domain, that is, occupying the channel bandwidth. Requirements, the bandwidth of the carrier on the unlicensed spectrum is 20MHz, which corresponds to 106 physical resource blocks for 15kHz SCS and 51 physical resource blocks for 30kHz SCS. Obviously, continuing to use 11 consecutive physical resource block mapping methods cannot meet regulatory requirements.

In addition, regulatory regulations limit the transmit power at 1MHz, such as 10dB/MHz, and using 11 consecutive physical resource block mapping methods will reduce the transmit power of the S-SS/PSBCH block, thereby affecting coverage.

The technical solutions provided by this application are designed to solve the above technical problems.

The main idea of the solution of this application is that the synchronization signal may contain at least one kind of information, for example, the first information is used for automatic gain control estimation, and/or is used to carry the physical broadcast channel and/or demodulation reference signal; the second information It is used to carry the primary synchronization sequence; the third information is used to carry the secondary synchronization sequence; the fourth information is used to carry the physical broadcast channel and/or demodulation reference signal. This application uses the physical resource blocks mapped by various information in the frequency domain. The distribution position of the synchronization sequence and/or the sequence length used in the synchronization sequence are adjusted so that the bandwidth range occupied by the synchronization signal in frequency meets regulatory requirements (such as OCB>80%). In addition, the bandwidth increase can also correspondingly increase the transmission of the synchronization signal. power, thus helping to improve signal coverage.

It can be understood that the processing steps of the processing method in this application can be implemented by a terminal device.

The terminal device can be a wireless terminal or a wired terminal. A wireless terminal may refer to a device that provides voice and/or other service data connectivity to a user, a handheld device with wireless connectivity capabilities, or other processing device connected to a wireless modem.

The comb structure is called an interlace, and the entire carrier bandwidth or resource pool is divided into several interlaces. Optionally, the number of interleavings is negatively correlated with the subcarrier spacing. For example, when the subcarrier spacing is 15 kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30 kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15/30kHz, every 10th/5th resource block belongs to the same interlace.

Optionally, the spacing distance between physical resource blocks is inversely related to the subcarrier spacing.

For example, if the subcarrier spacing is 15 kHz, the spacing distance between physical resource blocks is 10, and if the subcarrier spacing is 30 kHz, the spacing distance between physical resource blocks is 5. Here, a resource block mapped by the information and subsequent unmapped consecutive resource blocks can be regarded as an "interleave".

For example, when the subcarrier spacing is 15 kHz, it is divided into 10 interleavings, and when the subcarrier spacing is 30 kHz, it is divided into 5 interleavings. Therefore, for a subcarrier spacing of 15/30kHz, every 10th/5th resource block belongs to the same interlace.
