US 2018/0124749 A1 · METHOD FOR ALLOCATING RESOURCES IN CELLULAR NETWORK USING UNLICENSED BAND AND DEVICE THEREFOR

Abstract

Disclosed is a 5G or pre-5G communication system provided so as to support a data transmission rate higher than that of a 4G communication system, such as LTE. A method and a device for transmitting information in a communication system are disclosed. The method for allocating resources in a cellular network using an unlicensed band comprises the steps of: generating at least one resource allocation signal containing information indicating a plurality of continuous uplink subframes capable of communicating through the unlicensed band; transmitting the resource allocation signal to a user equipment (UE) through the unlicensed band for the duration of at least one downlink subframe; and receiving uplink data from the UE for the duration of the continuous uplink subframes.

Claims22

Dependent claims

A method for allocating a resource in a cellular network using an unlicensed band, the method comprising:

generating at least one resource assignment signal comprising information indicating a plurality of consecutive uplink (UL) subframes communicable through the unlicensed band;
transmitting the resource assignment signal to a user equipment (UE) through the unlicensed band during at least one downlink (DL) subframe;
and
receiving UL data from the UE during the consecutive UL subframes.

1 more element

A method for receiving resource allocation in a cellular network using an unlicensed band, the method comprising:

receiving at least one resource assignment signal comprising information indicating a plurality of consecutive uplink (UL) subframes communicable through the unlicensed band from an evolved NodeB (eNB) during at least one downlink (DL) subframe;
identifying the plurality of consecutive UL subframes based on the resource assignment signal and other control signals;
and
transmitting UL data to the eNB during the consecutive UL subframes.

1 more element

A user equipment (UE) for receiving resource allocation in a cellular network using an unlicensed band, the UE comprising:

a transceiver configured to receive at least one resource assignment signal comprising information indicating a plurality of consecutive uplink (UL) subframes communicable through the unlicensed band from an evolved NodeB (eNB) during at least one downlink (DL) subframe and to transmit UL data to the eNB during the consecutive UL subframes;
and
a controller configured to identify the plurality of consecutive UL subframes based on the resource assignment signal and the other control signals and to notify the transceiver of the identified consecutive UL subframes.

Dependencies are inferred from the claim text.
