Description

Technical Field

[0001] This application belongs to the field of mobile communication technology, and specifically relates to a method, apparatus and terminal for configuring random access timing. Background Technology

[0002] In existing communication systems, the Physical Random Access Channel (PRACH) is used to transmit preambles. Each PRACH occasion (RO) can only transmit one preamble, but multiple terminals can use the same RO to transmit different preambles.

[0003] In the FR2 band of New Radio (NR), PRACH supports a maximum PRACH subcarrier spacing of 120 kHz and a continuous RO configuration within only one PRACH slot. However, in the B52.6 GHz system, a higher PRACH subcarrier spacing is introduced, such as 480 kHz / 960 kHz, with corresponding Orthogonal Frequency Division Multiplexing (OFDM) symbol lengths of only 2.2 μs / 1.1 μs. On the one hand, considering the Listen before Talk (LBT) behavior in the unlicensed B52.6 GHz spectrum, the cyclic prefix (CP) length of the 480 kHz / 960 kHz OFDM symbol may be insufficient to cover the LBT spacing (GAP). On the other hand, considering beamswitching, the CP length of the 480 kHz / 960 kHz OFDM symbol may also be insufficient to cover the beam switching GAP.

[0004] It is evident that existing random access timing configuration methods are prone to causing PRACH transmission failures and reducing communication efficiency. Summary of the Invention

The execution module is used for: Based on the first information, configure a random access opportunity in the PRACH time slot; Based on the configuration results, determine the location of the random access opportunity in the PRACH time slot; The execution module is configured to obtain the starting symbol position of the random access opportunity in the PRACH time slot based on the third information and a preset algorithm; wherein the third information includes at least one of the following: The starting symbol position of the first random access opportunity within the PRACH time slot; The random access opportunity is numbered within the corresponding PRACH time slot; The duration of the random access opportunity; The interval between two adjacent random access opportunities within the PRACH time slot; Index of PRACH slots within a reference slot based on the second subcarrier interval; The preset algorithm is represented by the following formula: in, The starting symbol position of the random access timing. This refers to the starting symbol position of the first random access opportunity within the PRACH time slot. The random access opportunity is assigned a sequence number within its corresponding PRACH time slot. The duration of the random access opportunity. The interval between two adjacent random access opportunities within the PRACH time slot. The index of the PRACH time slot within the reference time slot. The number of symbols contained in each PRACH slot.

16. The apparatus according to claim 15, characterized in that, The execution module is used to perform at least one of the following: According to the first criterion, in the PRACH time slot, starting from the starting symbol position of the first random access opportunity in the PRACH time slot, a valid random access opportunity is configured based on the duration of the random access opportunity and the interval between two adjacent random access opportunities in the PRACH time slot; wherein, the valid random access opportunity is a random access opportunity that satisfies the first criterion. Based on the number of random access opportunities within the set of PRACH slots and the number of PRACH slots in the set of PRACH slots, the number of random access opportunities to be configured in each PRACH slot is determined. Then, based on the number of random access opportunities to be configured, starting from the starting symbol position of the first random access opportunity in the PRACH slot, random access opportunities are configured in the PRACH slot according to the duration of the random access opportunity and the interval between two adjacent random access opportunities in the PRACH slot.

17. A terminal, characterized in that, It includes a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the random access timing configuration method as described in any one of claims 1 to 14.

18. A readable storage medium, characterized in that, The readable storage medium stores a program or instructions that, when executed by a processor, implement the random access timing configuration method as described in any one of claims 1-14.
