Abstract

Disclosed are a resource management method and device and a computer storage medium. The method comprises: a node determining a resource management mode during carrier aggregation according to the type of a primary serving cell, and the node processing information according to the determined resource management mode.

First claim

1 . A resource management method, comprising:
determining, by a node, a management mode of a resource during carrier aggregation according to the type of a primary serving cell, and processing, by the node, information according to the determined management mode of the resource.

2 . The method according to claim 1 , wherein when the resource is a Downlink Control Information (DCI) format, determining, by the node, the management mode of the resource during carrier aggregation according to the type of the primary serving cell comprises:
when the primary serving cell is a Time Division Duplex (TDD) serving cell and a secondary serving cell is a Frequency Division Duplex (FDD) serving cell, determining, by the node, that a control field adopted by a DCI format of the FDD serving cell corresponds to a control field contained in a DCI format of the TDD serving cell.

3 . The method according to claim 2 , wherein determining that the control field adopted by the DCI format of the FDD serving cell corresponds to the control field contained in the DCI format of the TDD serving cell comprises:
determining to indicate a Hybrid Automatic Repeat Request (HARQ) process by using the value of an HARQ process number field and a control field other than the HARQ process number field; the method further comprising: when an HARQ process number corresponding to a Physical Downlink Shared CHannel (PDSCH) of the FDD serving cell is greater than 16, determining to extend an HARQ process number field in a DCI format corresponding to the PDSCH to 5 bits.

4 . The method according to claim 3 , wherein the control field other than the HARQ process number field refers to:
a Transmission Power Control (TPC) field, a Downlink Assignment Index (DAI) field or a subframe index.

5 . The method according to claim 2 , wherein determining that the control field adopted by the DCI format of the FDD serving cell corresponds to the control field contained in the DCI format of the TDD serving cell comprises:
determining to denote the accumulative number of assigned PDSCH transmission up to the present subframe among downlink subframes corresponding to uplink subframes in the FDD serving cell by using the value of a DAI field in a DCI format of the PDSCH of the FDD serving cell; or when cross-carrier scheduling is enabled and an uplink-downlink configuration of the TDD serving cell is a configuration {1, 2, 3, 4, 5, 6}, determining to denote the total number of assigned PDSCH transmission among downlink subframes corresponding to uplink subframes in the FDD serving cell, by using the value of a DAI field in a DCI format of a Physical Uplink Shared CHannel (PUSCH) of the FDD serving cell; or when cross-carrier scheduling is not enabled, determining to denote the total number of assigned PDSCH transmission, among the downlink subframes corresponding to the uplink subframes in the FDD serving cell, by using the value of a DAI field in the DCI format of the PUSCH of the FDD serving cell.

7 . The method according to claim 1 , wherein when the resource is a DCI format, determining, by the node, the management mode of the resource during carrier aggregation according to the type of the primary serving cell comprises:
when the primary serving cell is an FDD serving cell and a secondary serving cell is a TDD serving cell, determining, by the node, that a control field adopted by a DCI format of the TDD serving cell corresponds to a control field contained in a DCI format of the TDD serving cell.

8 . The method according to claim 7 , wherein determining that the control field adopted by the DCI format the TDD serving cell corresponds to the control field contained in the DCI format of the TDD serving cell comprises:
determining to denote whether PDSCHs on the serving cells are scheduled by using the value of a DAI field in a DCI format of a PDSCH of the TDD serving cell; or determining to cooperatively denote information of the control field by using the value of the DAI field in the DCI format of the PDSCH of the TDD serving cell and a control field other than the DAI field; or determining to denote whether the PDSCHs on the serving cells are scheduled by using the value of a DAI field in a DCI format of a PUSCH of the TDD serving cell.

9 . The method according to claim 8 , wherein denoting whether the PDSCHs on the serving cells are scheduled by using the value of the DAI field in the DCI format of the PDSCH of the TDD serving cell comprises:
determining to denote whether the PDSCHs on the serving cells are scheduled by using a 2-bit DAI field, the value of one bit in the 2-bit DAI field being used to denote whether a PDSCH on the primary serving cell is scheduled, and the value of the other one bit in the 2-bit DAI field being used to denote whether, among a plurality of secondary serving cells, a PDSCH on a serving cell with a maximum index, a PDSCH on a serving cell with a minimum index or a PDSCH on a serving cell indicated by higher layer signalling is scheduled; or determining to denote whether the PDSCH on the primary serving cell is scheduled by using the value of one bit in the 2-bit DAI field and denote whether PDSCHs on all of the plurality of secondary serving cells are scheduled by using the value of the other one bit in the 2-bit DAI field; or determining to denote a downlink HARQ process number of the TDD serving cell by using the value of 3 bits in an HARQ process number field in the DCI format of the PDSCH of the TDD serving cell, and cooperatively denote the information of the control field by using the value of the remaining one bit in the HARQ process number field and a control field other than the HARQ process number field.

10 . (canceled)

11 . The method according to claim 9 , wherein the control field other than the DAI field refers to: a TPC field or a Sounding Reference Signal (SRS) request field; and
the control field other than the HARQ process number field refers to: a TPC field or an SRS request field.

12 . The method according to claim 2 , wherein processing, by the node, the information according to the determined management mode of the resource comprises: processing, by the node, information on the serving cells according to the determined DCI format.

13 . The method according to claim 1 , wherein when the resource is for simultaneous transmission of uplink control information, determining, by the node, the management mode of the resource during carrier aggregation according to the type of the primary serving cell comprises:
when the primary serving cell is a TDD serving cell and a secondary serving cell is an FDD serving cell, determining, by the node, that the uplink control information is simultaneously transmitted by adopting a mechanism corresponding to the TDD serving cell; or when the primary serving cell is an FDD serving cell and the secondary serving cell is a TDD serving cell, determining, by the node, that the uplink control information is simultaneously transmitted by adopting a mechanism corresponding to the FDD serving cell.
