Abstract

A data sending method is provided. The data sending method includes: determining, according to location generation information of a PDCCH on a non-legacy resource, a resource location, on a subframe, of the PDCCH on the non-legacy resource; and sending the subframe to a UE, where the PDCCH on the non-legacy resource is contained on the resource location of the subframe, so that the UE determines the resource location, on the subframe, of the PDCCH on the non-legacy resource according to the location generation information. In the embodiments of the present invention, both the base station and the UE may determine a resource location of the PDCCH on the non-legacy resource separately by using the location generation information, thereby avoiding a circumstance that the UE equipped with only the capability of receiving a PDCCH on a non-legacy resource cannot access a network.

Claims

1. A non-transitory computer readable medium storing program codes for data sending by a base station, wherein the program codes when executed by a processor of the base station cause the processor to implement operations including:

determining, according to resource location information of a physical downlink control channel (PDCCH) on a next non-legacy resource, information concerning a resource location on a subframe of the next non-legacy resource in order to schedule the PDCCH on the next non-legacy resource;

sending a medium access control protocol data unit (MAC PDU) a non-legacy resource, wherein the MAC PDU comprises the resource location information of a the PDCCH on the next non-legacy resource; and

sending the PDCCH on the subframe of the next non-legacy resource, wherein a vacant bit of the MAC PDU is used to indicate the resource location of the PDCCH on the next non-legacy resource.

2. The non-transitory computer readable medium according to claim 1, wherein the MAC PDU further comprises a function of a temporary cell-radio network temporary identifier (TC-RNTI).

3. The non-transitory computer readable medium according to claim 2, wherein a correspondence exists between the resource location information of the PDCCH on the next non-legacy resource and the function of the TC-RNTI in the sent MAC PDU, and the correspondence is preset by a system.

4. The non-transitory computer readable medium according to claim 3, wherein the TC-RNTI in an interval is associated with the resource location of the PDCCH on the next non-legacy resource.

5. The non-transitory computer readable medium according to claim 1, wherein a correspondence between the vacant bit and two preset resource locations of the PDCCH on the next non-legacy resource is preset by a system.

6. The non-transitory computer readable medium according to claim 1, wherein a sub-header in a MAC header of the MAC PDU includes a random access preamble identifier (RAPID) domain indicating a special random access sequence.

7. The non-transitory computer readable medium according to claim 1, wherein the MAC PDU is a MAC PDU of a random access response (RAR).

8. The non-transitory computer readable medium according to claim 1, wherein a resource location of the PDCCH on the next non-legacy resource is indicated, so as to obtain a dynamic scheduling gain of the PDCCH on the next non-legacy resource.

9. A non-transitory computer readable medium storing program codes for data receiving by user equipment (UE), wherein the program codes when executed by a processor of the UE cause the processor to implement operation including:

determining, according to resource location information, a resource location on a subframe of a physical downlink control channel (PDCCH) on a non-legacy resource;

receiving a medium access control protocol data unit (MAC PDU) on the subframe of the non-legacy resource, wherein the MAC PDU comprises resource location information of the PDCCH on a next non-legacy resource; and

receiving the PDCCH on the next non-legacy resource, wherein a vacant bit of the MAC PDU is used to indicate the resource location of the PDCCH on the next non-legacy resource.

10. The non-transitory computer readable medium according to claim 9, wherein the resource location information of the PDCCH on the next non-legacy resource is a function of a temporary cell-radio network temporary identifier (TC-RNTI) in the received MAC PDU.

11. The non-transitory computer readable medium according to claim 9, wherein a correspondence between the vacant bit and two preset resource locations of the PDCCH on the next non-legacy resource is preset by a system.

12. The non-transitory computer readable medium according to claim 9, wherein a sub-header in a MAC header of the MAC PDU includes a random access preamble identifier (RAPID) domain indicating a special random access sequence.

13. The non-transitory computer readable medium according to claim 9, wherein the resource location information of the PDCCH on the next non-legacy resource is received at a presetting location of the MAC PDU.

14. The non-transitory computer readable medium according to claim 10, wherein a correspondence exists between the resource location information of the PDCCH on the next non-legacy resource and the function of the TC-RNTI in the receiving MAC PDU, and the correspondence is preset by a system.

15. The non-transitory computer readable medium according to claim 9, wherein the MAC PDU is a MAC PDU of a random access response (RAR).

16. The non-transitory computer readable medium according to claim 9, wherein a resource location of the PDCCH on the next non-legacy resource is indicated, so as to obtain a dynamic scheduling gain of the PDCCH on the next non-legacy resource.

17. A data sending apparatus comprising a processor, a transmitter, a receiver and a non-transitory memory storing program codes that, when executed by the processor, cause the data sending apparatus to implement operations including:

determining, according to resource location information of a physical downlink control channel (PDCCH) on a next non-legacy resource, information concerning a resource location on a subframe of the next non-legacy resource in order to schedule the PDCCH on the next non-legacy resource;

sending a medium access control protocol data unit (MAC PDU) a non-legacy resource, wherein the MAC PDU comprises the resource location information of the PDCCH on the next non-legacy resource; and

sending the PDCCH on the subframe of the next non-legacy resource, wherein a vacant bit of the MAC PDU is used to indicate the resource location of the PDCCH on the next non-legacy resource.

18. The data sending apparatus according to claim 17, wherein the MAC PDU further comprises a function of a temporary cell-radio network temporary identifier (TC-RNTI).

19. The data sending apparatus according to claim 18, wherein a correspondence between the vacant bit and two preset resource locations of the PDCCH on the next non-legacy resource is preset by a system.

20. The data sending apparatus according to claim 17, wherein the MAC PDU is a MAC PDU of a random access response (RAR).
