Abstract

Claims (50)

1 . A method performed by a first node establishing connection with a user equipment (UE) for supporting data transmission in a wireless communication system, the method comprising:

transmitting, to a second node, configuration information for reporting a status of a transmission leg;

receiving, from the second node, information on a leg status report in response to the configuration information;

transmitting, to a third node of a radio access network (RAN), a first message including at least one of first information for reporting status of one or more transmission legs of the first node or second information for reporting status of one or more transmission legs of the second node;

transmitting, to the third node, a second message including a leg identity and a quality of service (QoS) parameter; and

receiving, from the third node, a third message including information on transmission leg selection,

wherein the information on the leg status report includes information on an average channel quality indicator (CQI), information a hybrid automatic repeat request (HARQ) failure time, and information on HARQ retransmission, and

wherein the first node corresponds to a hosting node and the second node corresponds to an assisting node.

2 . The method of claim 1 ,

wherein the second information is obtained based on the information on the leg status report.

3 . The method of claim 1 , wherein the configuration information includes at least one of: a service type, a measurement interval, a reporting period, an indication indicating to start or to stop transmission of assistance information, a type of assistance information required to be reported, or a leg identity.

4 . A method performed by a third node for supporting data transmission in a wireless communication system, the method comprising:

receiving, from a first node establishing connection with a user equipment (UE), a first message including at least one of first information for reporting status of one or more transmission legs of the first node or second information for reporting status of one or more transmission legs of a second node;

receiving, from the first node, a second message including a leg identity and a quality of service (QoS) parameter; and

transmitting, to the first node, a third message including information on transmission leg selection based on the second message,

wherein the information on transmission leg selection is obtained based on the first message and the second message,

wherein each of the first information and the second information includes information on an average channel quality indicator (CQI), information a hybrid automatic repeat request (HARQ) failure time, and information on HARQ retransmission, and

wherein the first node corresponds to a hosting node and the second node corresponds to an assisting node.

5 . The method of claim 4 , wherein the method further comprises:

wherein configuration information for reporting a status of a transmission leg is transmitted from the first node to the second node,

wherein information on a leg status report is transmitted from the second node to the first node based on the configuration information, and

wherein the configuration information includes at least one of: a service type, a measurement interval, a reporting period, an indication indicating to start or to stop transmission of assistance information, a type of assistance information required to be reported, or a leg identity.

6 . A first node establishing connection with a user equipment (UE) for supporting data transmission in a wireless communication system, the first node comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the first node to:

transmit, to a second node, configuration information for reporting a status of a transmission leg,

receive, from the second node, information on a leg status report in response to the configuration information,

transmit, to a third node of a radio access network (RAN), a first message including at least one of first information for reporting status of one or more transmission legs of the first node or second information for reporting status of one or more transmission legs of the second node,

transmit, to the third node, a second message including a leg identity and a quality of service (QoS) parameter, and

receive, from the third node, a third message including information on transmission leg selection,

wherein the information on the leg status report includes information on an average channel quality indicator (CQI), information a hybrid automatic repeat request (HARQ) failure time, and information on HARQ retransmission, and

wherein the first node corresponds to a hosting node and the second node corresponds to an assisting node.

7 . The first node of claim 6 , wherein the second information is obtained based on the information on the leg status report.

8 . The first node of claim 6 , wherein the configuration information includes at least one of: a service type, a measurement interval, a reporting period, an indication indicating to start or to stop transmission of assistance information, a type of assistance information required to be reported, or a leg identity.

9 . A third node for supporting data transmission in a wireless communication system, the third node comprising:

at least one transceiver;

at least one processor communicatively coupled to the at least one transceiver; and

at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the third node to:

receive, from a first node establishing connection with a user equipment (UE), a first message including at least one of first information for reporting status of one or more transmission legs of the first node or second information for reporting status of one or more transmission legs of a second node,

receive, from the first node, a second message including a leg identity and a quality of service (QoS) parameter, and

transmit, to the first node, a third message including information on transmission leg selection based on the second message,

wherein the information on the transmission leg selection is obtained based on the first message and the second message,

wherein each of the first information and the second information includes information on an average channel quality indicator (CQI), information a hybrid automatic repeat request (HARQ) failure time, and information on HARQ retransmission, and

wherein the first node corresponds to a hosting node and the second node corresponds to an assisting node.

10 . The third node of claim 9 ,

wherein configuration information for reporting a status of a transmission leg is transmitted from the first node to the second node, and

wherein information on a leg status report is transmitted from the second node to the first node based on the configuration information.

11 . The third node of claim 10 ,

wherein the configuration information includes at least one of: a service type, a measurement interval, a reporting period, an indication indicating to start or to stop transmission of assistance information, a type of assistance information required to be reported, or a leg identity.
