When a subframe format is a format (b) and ns=0, details are as follows:
Calculation manners of identifiers bki of GF transmission sub-bands that can be used by a terminal 1 with an ID of 1 and a terminal with an ID of 2 are the same as those in the foregoing. Details are not described herein again.
In addition, when an identifier of a symbol meets ns=1, calculation of the identifiers bki of the GF transmission sub-bands that can be used by the terminal 1 and a terminal 2 is as follows:
When the identity ID nk of the terminal k meets nk=1, based on the foregoing formula (1), the following results are obtained.
An identifier of a sub-band corresponding to a first GF time-frequency resource of a terminal whose ID is 1 is as follows: b11=0·4+(1+1) mod 4=2.
An identifier of a sub-band corresponding to a second GF time-frequency resource of a terminal whose ID is 1 is as follows: b12=1·4+(1+1) mod 4=6.
An identifier of a sub-band corresponding to a third GF time-frequency resource of a terminal whose ID is 1 is as follows: b13=2·4+(1+1) mod 4=10.
When the identity ID nk of the terminal k meets nk=2, based on the foregoing distribution rule formula, the following results are obtained.
An identifier of a sub-band corresponding to a first GF time-frequency resource of a terminal whose ID is 2 is as follows: b21=0·4+(1+2) mod 4=3.
An identifier of a sub-band corresponding to a second GF time-frequency resource of a terminal whose ID is 2 is as follows: b22=1·4+(1+2) mod 4=7.
