Abstract
A communication method includes, when a rate adaptation or a frequency offset adjustment is performed on a first block sequence, a quantity of first preset blocks that are added or deleted is one of one or more preset values. In this way, a receive end may determine, based on whether the quantity of first preset blocks in the received first block sequence is a preset value, whether an exception occurs in the first preset block during transmission. Based on this, a false packet can be accepted as a correct packet less frequently, thereby improving a mean time to false packet acceptance (MTTFPA) indicator.
Claims20
A method comprising:
- obtaining a first block sequence;
- deleting a first quantity of continuous first preset blocks from the first block sequence based on a rate adaptation or a frequency offset adjustment requirement when a first block is to be deleted from the first block sequence to obtain a modified first block sequence, wherein the first quantity is an integer greater than 1 and is one of one or more preset values;
- adding a second quantity of continuous first preset blocks to the first block sequence based on the rate adaptation or the frequency offset adjustment requirement when a second block is to be added to the first block sequence to obtain the modified first block sequence, wherein the second quantity is an integer greater than 1 and is one of the one or more preset values;
- transmitting the modified first block sequence;
- and
- either:
- (1) multiplexing Q1 obtained first block sequences to generate a second block sequence and transmitting the second block sequence, wherein Q1 is a positive integer;
- or
- (2) multiplexing the Q1 obtained first block sequences to generate the second block sequence, generating a third block sequence based on the second block sequence, multiplexing the third block sequence and at least one fourth block sequence to obtain a fifth block sequence, and transmitting the fifth block sequence.

A method comprising:
- obtaining a first block sequence comprising a first quantity of continuous first preset blocks;
- determining that a first exception occurs in a first packet corresponding to the first preset blocks during transmission when the first quantity is not one of one or more preset values, wherein the first block sequence further comprises at least one data unit, and wherein the at least one data unit comprises a series of continuous blocks;
- and
- inserting at least one second preset block into one data unit in the at least one data unit when the one data unit comprises a first preset block and a second quantity of the first preset blocks comprised in the one data unit is not one of the one or more preset values, and wherein the at least one second preset block indicates that a second exception occurs in a second packet corresponding to the one data unit during the transmission.
1 more element
A device comprising:
- a communication interface;
- and
- one or more processors coupled to the communication interface and configured to:
- obtain a first block sequence;
- delete a first quantity of continuous first preset blocks from the first block sequence based on a rate adaptation or a frequency offset adjustment requirement when a block is to be deleted from the first block sequence to obtain a modified first block sequence, wherein the first quantity is an integer greater than 1 and is one of one or more preset values;
- add a second quantity of continuous first preset blocks to the first block sequence based on the rate adaptation or the frequency offset adjustment requirement when a block is to be added to the first block sequence to obtain the modified first block sequence, wherein the second quantity is an integer greater than 1 and is one of the one or more preset values;
- transmit the modified first block sequence through the communication interface;
- identify that a third quantity of continuous first preset blocks comprised in the first block sequence is not one of the one or more preset values;
- and
- determine, in response to identifying that the third quantity is not the one of the one or more preset values, that an exception occurs in a packet corresponding to the first preset blocks during transmission.
