## Abstract

A terminal apparatus performs transmission and/or reception in units of subframes, and receives the control signal arranged in accordance with a predefined format having a predetermined size in bits and comprising one or more sets of bits each containing one or more bits from a base station; wherein within the format, a first set of bits is intended for one or more terminal apparatus and a second set of bits distinct from the first set of bits is intended for other terminal apparatus; and wherein transmission and/or reception by the terminal apparatus in a subsequent subframe is determined by the said set of bits of the control signal.

## Claims

### Claim 1

A terminal apparatus performs transmission and/or reception in units of subframes, and receives the control signal arranged in accordance with a predefined format having a predetermined size in bits and comprising one or more sets of bits each containing one or more bits from a base station;
wherein within the format, a first set of bits is intended for one or more terminal apparatus and a second set of bits distinct from the first set of bits is intended for other terminal apparatus; and
wherein transmission and/or reception by the terminal apparatus in a subsequent subframe is determined by the said set of bits of the control signal.

### Claim 2 (depends on 1)

The terminal apparatus according to claim 1, wherein the transmission and/or reception by the terminal apparatus in the subsequent subframe depends on timing of reception of the control signal.

### Claim 3 (depends on 1)

The terminal apparatus according to claim 1, wherein the transmission and/or reception by the terminal apparatus in the subsequent subframe depends on value(s) of the first set of bits.

### Claim 4 (depends on 1)

The terminal apparatus according to claim 1, wherein the first set of bits is also intended for the one terminal apparatus.

### Claim 5 (depends on 1)

The terminal apparatus according to claim 1, wherein the sets of bits include sets of bits representing values of one or more parameters.

### Claim 6 (depends on 1)

The terminal apparatus according to claim 1, wherein the sets of bits include sets of bits representing a selection among predetermined sets of parameter values.

### Claim 7 (depends on 6)

The terminal apparatus according to claim 6, wherein the parameter values, or predetermined sets of parameter values, include parameter values for scheduling transmission and/or reception of the terminal apparatus.

### Claim 8 (depends on 1)

The terminal apparatus according to claim 1, wherein the first set of bits includes at least one bit indicating any one of:
whether transmission and/or reception is to be performed in the current subframe either on a downlink and/or on an uplink;
whether transmission and/or reception is to be performed in subsequent subframes either on a downlink and/or on an uplink;
whether transmission and/or reception is to be performed in a defined subframe which is a defined number of subframes from the current subframe;
whether semi-persistent scheduling, SPS operation is to be activated or deactivated;
a selection among predetermined sets of parameter values for scheduling; and
a selection among a predetermined set of carrier frequencies for scheduling.

### Claim 9

A terminal apparatus for use in a communication system, the communication system comprising:
the terminal apparatus configured to receive a control signal from the base station in a current subframe and decode the control signal, the control signal arranged in accordance with a predefined format having a predetermined size in bits and comprising one or more sets of bits each containing one or more bits;
wherein within the format, a first set of bits is intended for one or more terminal apparatus and a second set of bits distinct from the first set of bits is intended for other terminal apparatus; and
wherein a transmission and/or reception by the one or the other terminal apparatus in a subsequent subframe is determined by the said set of bits of the control signal.
