Abstract
The disclosure relates to a method and device for efficiently estimating a self-interference channel in an FD communication system. A method for estimating a self-interference channel by a BS in an FD communication system includes transmitting, to a first UE, information about an uplink resource where uplink reception from the first UE is muted; and estimating a self-interference channel related to downlink transmission in a period corresponding to the uplink resource where uplink reception is muted during downlink transmission to a second UE, based on the transmitted information.
Claims17
A method performed by a base station (BS) in a full-duplex (FD) communication system, the method comprising:
- transmitting, to a first user equipment (UE), information about an uplink resource in which uplink reception from the first UE is muted;
- and
- estimating a self-interference channel related to downlink transmission in a period corresponding to the uplink resource, where uplink reception is muted during downlink transmission to a second UE, based on the transmitted information,
- wherein the transmitted information includes a position of a muting symbol or a muting resource element (RE) and at least one of a repetition period, a repetition time, or a number of repetitions of the muting symbol or the muting RE.
A base station (BS) for use in a full-duplex (FD) communication system, the BS comprising:
- a transceiver;
- and
- a processor configured to:
- transmit, through the transceiver, to a first user equipment (UE), information about an uplink resource in which uplink reception from the first UE is muted, and
- estimate a self-interference channel related to downlink transmission in a period corresponding to the uplink resource, where uplink reception is muted during downlink transmission to a second UE, based on the transmitted information,
- wherein the transmitted information includes a position of a muting symbol or a muting resource element (RE) and at least one of a repetition period, a repetition time, or a number of repetitions of the muting symbol or the muting RE.
A method performed by a user equipment (UE) in a full-duplex (FD) communication system, the method comprising:
- receiving, from a base station (BS), information about an uplink resource in which uplink reception is muted;
- and
- performing uplink transmission in a remaining uplink resource, except for the uplink resource, while not performing uplink transmission in a period corresponding to the uplink resource, based on the received information,
- wherein the transmitted information includes a position of a muting symbol or a muting resource element (RE) and at least one of a repetition period, a repetition time, or a number of repetitions of the muting symbol or the muting RE.
A user equipment (UE) for use in a full-duplex (FD) communication system, the UE comprising:
- a transceiver;
- and
- a processor configured to:
- receive, through the transceiver, from a base station (BS), information about an uplink resource in which uplink reception is muted, and
- perform uplink transmission in a remaining uplink resource, except for the uplink resource, while not performing uplink transmission in a period corresponding to the uplink resource, based on the received information,
- wherein the transmitted information includes a position of a muting symbol or a muting resource element (RE) and at least one of a repetition period, a repetition time, or a number of repetitions of the muting symbol or the muting RE.
