## Abstract

A method for receiving a signal in a user equipment (UE) from a base station (BS) in a wireless communication system is disclosed. The method comprises the steps of configuring a plurality of intervals of a specific time region for indicating whether to transmit the signal, through a higher layer; receiving an indicator for indicating whether to transmit the signal, for each of the plurality of intervals; and receiving a signal in each of the plurality of intervals in accordance with indication of the received indicator, wherein at least one of the plurality of intervals of the specific time region may have a first size, and the other intervals except the at least one interval may have a second size.

## Claims

### Claim 1

A method for transmitting a downlink signal by a base station (BS) in a wireless communication system, the method comprising:
transmitting information for informing whether a downlink signal is transmitted in each of a plurality of durations included in a specific time region; and
transmitting the downlink signal based on the information,
wherein a number of the plurality of durations is M,
wherein the plurality of durations include i) one or more first durations in which each of the first durations has a first size and ii) one or more second durations in which each of the second durations has a second size, and
wherein the first size is defined by Ceil(T/M), and the second size is defined by Floor(T/M),
where T denotes a number of symbols of the specific time region.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the first size and the second size are different.

### Claim 3 (depends on 1)

The method according to claim 1, wherein a number of the one or more first durations having the first size is M−Floor(M×Ceil(T/M)−T) and a number of the one or more second durations having the second size is Floor(M×Ceil(T/M)−T).

### Claim 4 (depends on 1)

The method according to claim 1, wherein the plurality of durations are configured for the specific time region and a specific frequency region.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the specific time region includes the plurality of durations and a time region for uplink transmission.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the information includes a plurality of bits for informing whether the downlink signal is transmitted in each of the plurality of durations.

### Claim 7

A base station (BS) for transmitting a downlink signal in a wireless communication system, the BS comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
transmitting, via the at least one transceiver, information for informing whether a downlink signal is transmitted in each of a plurality of durations included in a specific time region; and
transmitting, via the at least one transceiver, the downlink signal based on the information,
wherein a number of the plurality of durations is M,
wherein the plurality of durations include i) one or more first durations in which each of the first durations has a first size and ii) one or more second durations in which each of the second durations has a second size, and
wherein the first size is defined by Ceil(T/M), the second size is defined by Floor(T/M),
where T denotes a number of symbols of the specific time region.

### Claim 8 (depends on 7)

The BS according to claim 7, wherein the first size and the second size are different.

### Claim 9 (depends on 7)

The BS according to claim 7, wherein a number of the one or more first durations having the first size is M−Floor(M×Ceil(T/M)−T) and a number of the one or more second durations having the second size is Floor(M×Ceil(T/M)−T).

### Claim 10 (depends on 7)

The BS according to claim 7, wherein the plurality of durations are configured for the specific time region and a specific frequency region.

### Claim 11 (depends on 7)

The BS according to claim 7, wherein the specific time region includes the plurality of durations and a time region for uplink transmission.

### Claim 12 (depends on 7)

The BS according to claim 7, wherein the information includes a plurality of bits for informing whether the downlink signal is transmitted in each of the plurality of durations.
