Abstract
A method and apparatus for early frequency reporting for fast carrier aggregation (CA) and/or dual connectivity (DC) setup in a wireless communication system is provided. A wireless device reports, to a network, information informing that a neighbor frequency can be aggregated with a serving frequency using one of 1) carrier aggregation (CA), 2) dual connectivity (DC), or 3) both CA and DC.
Claims12
A method performed by a wireless device operating in a wireless communication system, the method comprising:
- receiving, from a network, an idle/inactive measurement configuration for a measurement in a radio resource control (RRC) idle state and/or an RRC inactive state, wherein the idle/inactive measurement configuration includes a list of one or more frequencies to be measured;
- performing the measurement based on the idle/inactive measurement configuration while in the RRC idle state and/or the RRC inactive state;
- transmitting, to the network, a connection request message to transition from the RRC idle state and/or the RRC inactive state to an RRC connected state;
- receiving, from the network, a response message in response to the connection request message;
- identifying at least one frequency, from among the one or more frequencies, of which at least one cell is valid based on results of the measurement;
- checking whether a specific frequency from among the at least one frequency is capable of a carrier aggregation (CA) operation and/or a dual connectivity (DC) operation with a serving frequency;
- and
- based on the specific frequency being capable of the CA operation and/or the DC operation with the serving frequency, reporting, to the network, information regarding the specific frequency and cell identifiers (IDs) associated with the specific frequency.

A wireless device configured to operate in a wireless communication system, the wireless device 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, based on being executed by the at least one processor, perform operations comprising:
- receiving, from a network using the at least one transceiver, an idle/inactive measurement configuration for a measurement in a radio resource control (RRC) idle state and/or an RRC inactive state, wherein the idle/inactive measurement configuration includes i) a list of one or more frequencies to be measured;
- performing the measurement based on the idle/inactive measurement configuration while in the RRC idle state and/or the RRC inactive state;
- transmitting, to the network using the at least one transceiver, a connection request message to transition from the RRC idle state and/or the RRC inactive state to an RRC connected state;
- receiving, from the network using the at least one transceiver, a response message in response to the connection request message;
- identifying at least one frequency, from among the one or more frequencies, of which at least one cell is valid based on results of the measurement;
- checking whether a specific frequency from among the at least one frequency is capable of a carrier aggregation (CA) operation and/or a dual connectivity (DC) operation with a serving frequency;
- and
- based on the specific frequency being capable of the CA operation and/or the DC operation with the serving frequency, reporting, to the network using the at least one transceiver, information regarding the specific frequency and cell identifiers (IDs) associated with the specific frequency.
