Abstract
A method, a base station (BS), and a user terminal are provided for implementing uplink resource indication. The method includes carrying an uplink resource index in an uplink resource grant (UL Grant), in which an uplink resource index corresponds 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.
Claims19
A method for implementing an uplink resource grant (UL Grant), comprising:
- identifying, by a base station, a downlink subframe in a plurality of downlink subframes in a radio frame, wherein each downlink subframe corresponds to an unique uplink subframe set, each uplink subframe set comprises a plurality of uplink subframe groups, each uplink subframe group corresponds to an uplink resource index and is identified by the uplink resource index, each uplink subframe group has an unique uplink subframe grouping specifying at least one uplink subframe in a time domain, and at least one group in the plurality of uplink subframe groups comprises at least two uplink subframes;
- and
- sending, by the base station, an UL Grant to a user terminal on the downlink subframe, wherein the UL Grant includes a first uplink resource index corresponding to a first uplink subframe group in a first uplink subframe set, and the first uplink subframe set corresponds to the downlink subframe.
A base station, comprising:
- a processor, configured to identify a downlink subframe in a plurality of downlink subframes in a radio frame, wherein each downlink subframe corresponds to an unique uplink subframe set, each uplink subframe set comprises a plurality of uplink subframe groups, each uplink subframe group corresponds to an uplink resource index and is identified by the uplink resource index, each uplink subframe group has an unique uplink subframe grouping specifying at least one uplink subframe in a time domain, and at least one group in the plurality of uplink subframe groups corresponds to at least two uplink subframes;
- and
- a transmitter, configured to send an uplink resource grant (UL Grant) to a user terminal on the downlink subframe, wherein the UL Grant includes a first uplink resource index, the first uplink resource index corresponds to a first uplink subframe group in a first uplink subframe set, and the first uplink subframe set corresponds to the downlink subframe.
A method for implementing an uplink resource grant (UL Grant) comprising:
- identifying, by a processor, a downlink subframe in a plurality of downlink subframes in a radio frame, wherein each downlink subframe corresponds to an unique uplink subframe set comprising a plurality of uplink subframe groups, each uplink subframe group corresponds to an uplink resource index and identified by the uplink resource index, each uplink subframe group has an unique uplink subframe grouping specifying at least one uplink subframe in a time domain, and at least one group in the plurality of uplink subframe groups comprises at least two uplink subframes;
- and
- controlling, by the processor, transmission of a user terminal uplink resource grant on the downlink subframe, wherein the UL Grant including a first uplink resource index corresponds to a first uplink subframe group in a first uplink subframe set, and the first uplink subframe set corresponds to the downlink subframe.
An apparatus, comprising:
- a storage medium including executable instructions;
- and
- a processor;
- wherein the executable instructions, when executed by the processor, cause the apparatus to:
- identify a downlink subframe in a plurality of downlink subframes in a radio frame, each downlink subframe corresponding to an unique uplink subframe set, each uplink subframe set comprising a plurality of uplink subframe groups corresponding to an uplink resource index and identified by the uplink resource index, each uplink subframe group having an unique uplink subframe grouping specifying at least one uplink subframe in a time domain, and at least one group in the plurality of uplink subframe groups comprising at least two uplink subframes;
- control transmission of an uplink resource grant (UL Grant) on the downlink subframe, the UL Grant including a first uplink resource index resource index corresponding to a first uplink subframe group in a first uplink subframe set, and the first uplink subframe set corresponding to the downlink subframe.

An apparatus, comprising:
- a storage medium including executable instructions;
- and
- a processor;
- wherein the executable instructions, when executed by the processor, cause the apparatus to:
- control reception of an uplink resource grant (UL Grant) from a base station on a downlink subframe in a radio frame, each downlink subframe corresponding to an unique uplink subframe set having a plurality of uplink subframe groups, each uplink subframe group corresponding to an uplink resource index and is identified by the uplink resource index, each uplink subframe group having an unique uplink subframe grouping specifying at least one uplink subframe in a time domain, and at least one group in the plurality of uplink subframe groups comprising at least two uplink subframes;
- identify the downlink subframe on which the UL Grant is received, the UL Grant including a first uplink resource index corresponding to a first uplink subframe group in a first uplink subframe set and identifying the first uplink subframe group, and the first uplink subframe set corresponding to the downlink subframe;
- identify the first uplink subframe group identified by the first uplink resource index;
- and
- control transmission of data on each of at least one uplink subframes specified in the time domain in the first uplink subframe group.
