Method and device for configuring shared cell in communication system
A method performed by a middle node in a communication system includes: receiving a request message for capability information from a controller, transmitting capability information of the middle node as a response to the request message; and receiving timing information corresponding to multiple subcarrier spacings (SCSs) from the controller based on the capability information of the middle node.
1 . A method performed by a middle node in a communication system, the method comprising:
receiving, from a controller, a request message for capability information;
transmitting capability information of the middle node in response to the request message, wherein the capability information indicates whether the middle node supports processing uplink data containing multiple subcarrier spacings (SCSs) within a single extended Antenna-carrier ID (eAxC ID); and
receiving, from the controller, timing information based on the capability information of the middle node, wherein the timing information is configured for the multiple SCSs within the single eAxC ID for processing the uplink data.
2 . The method of claim 1 , wherein the capability information of the middle node further comprises:
information indicating a maximum time required when the middle node performs uplink data combining.
3 . The method of claim 1 , wherein the timing information configured for to the multiple SCSs comprises:
information indicating latest timing at which the middle node transmits combined uplink data to a first communication node.
4 . The method of claim 1 , further comprising:
receiving, from the controller, information indicating that one eAxC ID includes multiple SCS in uplink data to be received by the middle node.
5 . The method of claim 1 , wherein the middle node is a fronthaul multiplexer (FHM) or a cascade radio unit (RU).
6 . A middle node in a communication system, the middle node comprising:
a transceiver;
a memory; and
at least one processor electrically connected to the transceiver and the memory,
wherein the at least one processor is configured to:
receive, from a controller, a request message for capability information;
transmit capability information of the middle node in response to the request message, wherein the capability information indicates whether the middle node supports processing uplink data containing multiple subcarrier spacings (SCSs) within a single extended Antenna-carrier ID (eAxC ID); and
receive, from the controller, timing information based on the capability information of the middle node, wherein the timing information is configured for the multiple SCSs within the single eAxC ID for processing the uplink data.
7 . The method of claim 6 , wherein the capability information of the middle node further comprises:
information indicating a maximum time required when the middle node performs uplink data combining.
8 . The method of claim 6 , wherein the timing information configured for to the multiple SCSs comprises:
information indicating latest timing at which the middle node transmits combined uplink data to a first communication node.
9 . The method of claim 6 , wherein the at least one processor is further configured to:
receive, from the controller, information indicating that one eAxC ID includes multiple SCS in uplink data to be received by the middle node.
10 . The method of claim 6 , wherein the middle node is a fronthaul multiplexer (FHM) or a cascade radio unit (RU).
