Benefits of technology

[0019]It is known from the above technical solutions that the method, BS, and user terminal for implementing uplink resource indication according to the embodiments of the present invention realize accurate indication of the at least one uplink resource through the uplink resource index, prevent repeated transmission of the same information in multiple uplink resources, effectively reduce the signaling overhead, and increase the resource utilization.

Problems solved by technology

Thus, the information such as the user identity is also repeatedly transmitted for n times, resulting in the waste of transmission resources such as signaling and channels.

first embodiment

[0036]FIG. 5 is a schematic flow chart of a method for implementing uplink resource indication according to the present invention.

[0037]In Step 501, a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication is established.

[0038]The method for establishing the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication includes the following steps. The at least one uplink resource is combined into one group, and the uplink resources in each group are not completely the same. Each group is corresponding to an uplink resource index, so as to establish the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication.

[0039]In this embodiment, uplink resource indexes of different bits are applied to different frame structures, so that different corresponding relations between the uplink resource index and at least one upli...

second embodiment

[0051]FIG. 6 is a schematic flow chart of a method for implementing uplink resource indication according to the present invention.

[0052]In Step 601, all uplink resources are grouped in at least one uplink resource set in advance.

[0053]In this embodiment, all of the uplink resources are grouped into at least one uplink resource set according to the corresponding relation between the downlink SF for sending the ul grant and the uplink SFs in terms of indication.

[0054]In this embodiment, the frame structure in FIG. 2 is adopted, and the corresponding relation between the downlink SFs and the uplink SF set in terms of indication listed in Table 8 is set in advance. For example, when the uplink and downlink SF ratio is 4:3, if SF6 is configured to send the ul grant carrying the uplink resource index, the ul grant is directed to SF2; and if SF0 is configured to send the ul grant carrying the uplink resource index, the ul grant is directed to SF3 and SF4.

third embodiment

[0071]FIG. 7 is a schematic structural view of a BS for implementing uplink resource indication according to the present invention. The BS includes an index carrying module 701 and an instruction sending module 702.

[0072]The index carrying module 701 is configured to carry an uplink resource index in a ul grant, in which the uplink resource index is corresponding to at least one uplink resource in terms of indication.

[0073]The instruction sending module 702 is configured to send the ul grant generated by the index carrying module 701.

[0074]The BS further includes a mapping module 703.

[0075]The mapping module 703 is configured to establish a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication.

[0076]This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signa...

Abstract

A method, a base station (BS), and a user terminal for implementing uplink resource indication are provided. The method includes: carrying an uplink resource index in a ul grant, in which the uplink resource index is corresponding to at least one uplink resource in terms of indication; and sending the ul grant. The BS includes an index carrying module and an instruction sending module. The user terminal includes an instruction receiving module, an instruction resolving module, and an execution module.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 504,239, filed on Jul. 16, 2009, which is a continuation of International Application No. PCT / CN2008 / 071926, filed on Aug. 7, 2008. The International Application claims priority to Chinese Patent Application No. 200710140544.8, filed on Aug. 9, 2007. All of the afore-mentioned patent applications are hereby incorporated by reference in their entireties.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to the field of communications, and more particularly to a method, a base station (BS), and a user terminal for implementing uplink resource indication.BACKGROUND OF THE DISCLOSURE[0003]Time Division Duplex (TDD) is a radio transmission mode on radio channels. In the TDD mode, the transmission and reception are conducted in a time division manner, that is, the radio transmission based on the TDD mode realizes the time division multiplexing of uplink and downl...
