Abstract
A preamble sequence mapping method and a terminal are provided. The method includes: determining, by a terminal according to a rule for sorting T second preamble sequences, a target index of a second preamble sequence. The T second preamble sequences are all or some of sequences obtained after the terminal performs code-division on M first preamble sequences by using Q Orthogonal Cover Codes (OCCs). The method further includes establishing, by the terminal based on the target index of the second preamble sequence, mapping to a Synchronization Signal and Physical Broadcast Channel block (SSB). Q is an integer greater than or equal to 1. M is an integer greater than or equal to 1. T is an integer greater than or equal to 2.

A preamble sequence mapping method, comprising:
- determining, by a terminal, according to a rule for sorting T second preamble sequences, a target index of a second preamble sequence, wherein the T second preamble sequences are all or some of sequences obtained after the terminal performs code-division on M first preamble sequences by using Q Orthogonal Cover Codes (OCCs);
- and
- establishing, by the terminal, based on the target index of the second preamble sequence, mapping to a Synchronization Signal and Physical Broadcast Channel block (SSB), wherein
- Q is an integer greater than or equal to 1, M is an integer greater than or equal to 1, and T is an integer greater than or equal to 2,
- wherein the rule for sorting the T second preamble sequences comprises any one of the following:
- a first sorting rule of sorting first based on a serial number of a first preamble sequence and then based on a serial number of an OCC;
- a second sorting rule of sorting first based on a serial number of an OCC and then based on a serial number of a first preamble sequence;
- or
- a third sorting rule based on a group index after the second preamble sequences corresponding to different OCCs are grouped according to a preset rule, wherein an order within a group comprises:
- first based on a serial number of a first preamble sequence and then based on a serial number of an OCC, or first based on a serial number of an OCC and then based on a serial number of a first preamble sequence.
A terminal, comprising a processor;
- a memory having a computer program or an instruction stored thereon, wherein when executed by the processor, causes the processor to perform a preamble sequence mapping method, comprising:
- determining, according to a rule for sorting T second preamble sequences, a target index of a second preamble sequence, wherein the T second preamble sequences are all or some of sequences obtained after the processor performs code-division on M first preamble sequences by using Q Orthogonal Cover Codes (OCCs);
- and
- establishing, based on the target index of the second preamble sequence, mapping to a Synchronization Signal and Physical Broadcast Channel block (SSB), wherein
- Q is an integer greater than or equal to 1, M is an integer greater than or equal to 1, and T is an integer greater than or equal to 2,
- wherein the rule for sorting the T second preamble sequences comprises any one of the following:
- a first sorting rule of sorting first based on a serial number of a first preamble sequence and then based on a serial number of an OCC;
- a second sorting rule of sorting first based on a serial number of an OCC and then based on a serial number of a first preamble sequence;
- or
- a third sorting rule based on a group index after the second preamble sequences corresponding to different OCCs are grouped according to a preset rule, wherein an order within a group comprises:
- first based on a serial number of a first preamble sequence and then based on a serial number of an OCC, or first based on a serial number of an OCC and then based on a serial number of a first preamble sequence.
A non-transitory computer readable storage medium, storing a computer program or an instruction that, when executed by a processor, causes the processor to perform a preamble sequence mapping method, comprising:
- determining, according to a rule for sorting T second preamble sequences, a target index of a second preamble sequence, wherein the T second preamble sequences are all or some of sequences obtained after the terminal performs code-division on M first preamble sequences by using Q Orthogonal Cover Codes (OCCs);
- and
- establishing, based on the target index of the second preamble sequence, mapping to a Synchronization Signal and Physical Broadcast Channel block (SSB), wherein
- Q is an integer greater than or equal to 1, M is an integer greater than or equal to 1, and T is an integer greater than or equal to 2,
- wherein the rule for sorting the T second preamble sequences comprises any one of the following:
- a first sorting rule of sorting first based on a serial number of a first preamble sequence and then based on a serial number of an OCC;
- a second sorting rule of sorting first based on a serial number of an OCC and then based on a serial number of a first preamble sequence;
- or
- a third sorting rule based on a group index after the second preamble sequences corresponding to different OCCs are grouped according to a preset rule, wherein an order within a group comprises:
- first based on a serial number of a first preamble sequence and then based on a serial number of an OCC, or first based on a serial number of an OCC and then based on a serial number of a first preamble sequence.
