METHOD, BASE STATION, AND USER TERMINAL FOR IMPLEMENTING UPLINK RESOURCE INDICATION

1 . A method for implementing uplink resource indication, comprising:

receiving, by a user terminal, an uplink resource grant indication (ul grant) carrying an uplink resource index from a base station;

resolving, by the user terminal, the uplink resource index from the ul grant according to an obtained in advance a corresponding relation between the uplink resource index and the at least one uplink resource; the corresponding relation is obtained by:

combining the at least one uplink resource into one group, wherein the uplink resources in each group are not the same; and

making each group correspond to one uplink resource index, and establishing the corresponding relation between the uplink resource index and the at least one uplink resource;

performing, by the user terminal, resource grant on the obtained at least one uplink resource.

2 . The method according to claim 1 , before the step of combining the at least one uplink resource into one group comprises:

grouping, all uplink resources into at least one uplink resource set.

3 . The method according to claim 2 , wherein the corresponding relationship between the uplink resource index and at least one uplink resource is established by:

combining at least one uplink resource in each uplink resource set into one group, wherein the uplink resources in each group are not the same; and

making each group in the same uplink resource set correspond to one uplink resource index, and establishing the corresponding relation between the uplink resource index and the at least one uplink resource in the same uplink resource set.

4 . The method according to claim 1 , wherein the uplink resource comprises an uplink slot or an uplink subframe (SF).

5 . The method according to claim 1 , wherein the uplink resource index is formed by one of one bit, two bits, three bits, or four bits.

6 . A user terminal, comprising:

an instruction receiving module, configured to receive an uplink resource grant indication, ul grant, from a base station, BS;

an instruction resolving module, configured to resolve the uplink resource index from the ul grant according to an obtained in advance a corresponding relation between the uplink resource index and the at least one uplink resource; the corresponding relation being obtained by the following means:

combining the at least one uplink resource into one group, wherein the uplink resources in each group are not the same; and

making each group correspond to one uplink resource index, and establish ing the corresponding relation between the uplink resource index and the at least one uplink resource; and

an execution module, configured to perform resource grant on the obtained at least one uplink resource.

7 . The user terminal according to claim 6 , the execution module further configured to group all uplink resources into at least one uplink resource set.

8 . The user terminal according to claim 7 , the execution module further configured to:

combine at least one uplink resource in each uplink resource set into one group, wherein the uplink resources in each group are not completely the same; and

make each group in the same uplink resource set corresponding to one uplink resource index, and establish the corresponding relation between the uplink resource index and the at least one uplink resource in the same uplink resource set.

9 . A method for implementing uplink resource indication, comprising:

establishing, by a base station, a corresponding relation between an uplink resource index and the at least one uplink resource; the corresponding relation is obtained by the following means:

combining the at least one uplink resource into one group, wherein the uplink resources in each group are not the same; and

making each group corresponding to one uplink resource index, and establish the corresponding relation between the uplink resource index and the at least one uplink resource;

sending by the base station, the ul grant to a user terminal.

10 . The method according to claim 9 , before the step of combining the at least one uplink resource into one group comprises:

grouping, all uplink resources into at least one uplink resource set.

11 . The method according to claim 10 , wherein the corresponding relationship between the uplink resource index and at least one uplink resource is established by:

combining at least one uplink resource in each uplink resource set into one group, wherein the uplink resources in each group are not completely the same; and

making each group in the same uplink resource set correspond to one uplink resource index, and establishing the corresponding relation between the uplink resource index and the at least one uplink resource in the same uplink resource set.

12 . The method according to claim 9 , wherein the uplink resource comprises one of an uplink slot or an uplink subframe (SF).

13 . A base station (BS), comprising:

a mapping module, configured to establish a corresponding relation between the uplink resource index and the at least one uplink resource, wherein the corresponding relation is obtained by the following means:

combining, the at least one uplink resource into one group, wherein the uplink resources in each group are not completely the same; and

making each group correspond to one uplink resource index, and establish ing the corresponding relation between the uplink resource index and the at least one uplink resource;

an instruction sending module, configured to send the ul grant.

14 . The BS according to claim 13 , further comprising an index carrying module, configured to carry an uplink resource index in the uplink resource grant indication.

15 . The BS according to claim 13 , the mapping module further configured to group all uplink resources into at least one uplink resource set.
