Abstract
A method and apparatus for transmitting and receiving CQI in a wireless communication system are provided, in which when a UE transitions from a continuous reception state to a DRX state, CQI report resources are reallocated to the UE according to a CQI report resource reallocation rule agreed between the UE and an E-RAN, which obviates the need for signaling information about allocated new CQI report resources.
Claims20
A method of a User Equipment (UE) for transmitting Channel Quality Information (CQI) to a network in a wireless communication system supporting a continuous reception state for continuously monitoring a channel and a Discontinuous Reception (DRX) state for discontinuously monitoring the channel, the method comprising:
- receiving, from the network, CQI report resource information;
- reporting first CQI to the network according to the CQI report resource information in the continuous reception state;
- receiving, from the network, a DRX application signal indicating a transition from the continuous reception state to the DRX state;
- and
- reporting second CQI to the network, based on CQI report resources associated with the CQI report resource information, after receiving the DRX application signal.
A method for receiving Channel Quality Information (CQI) from a User Equipment (UE) by a network in a wireless communication system supporting a continuous reception state for continuously monitoring a channel and a Discontinuous Reception (DRX) state for discontinuously monitoring the channel, the method comprising:
- transmitting CQI report resource information to the UE;
- receiving, from the UE, first CQI according to the CQI report resource information in the continuous reception state;
- transmitting a DRX application signal to the UE indicating a transition from the continuous reception state to the DRX state;
- and
- receiving, from the UE, second CQI based on CQI report resources associated with the CQI report resource information, after transmitting the DRX application signal.
An apparatus of a User Equipment (UE) for transmitting Channel Quality Information (CQI) in a wireless communication system, the apparatus comprising:
- a signal transceiver for
- receiving, from a network, CQI report resource information, reporting first CQI to the network according to the CQI report resource information in a continuous reception state,
- receiving, from the network, a Discontinuous Reception (DRX) application signal indicating a transition from the continuous reception state to a DRX state, the continuous reception state being a state in which the UE continuously monitors a channel and the DRX state being a state in which the UE discontinuously monitors the channel, and
- reporting second CQI to the network based on CQI report resources associated with the CQI report resource information, after receiving the DRX state application signal;
- a DRX manager for determining whether a signal received from the signal transceiver indicates that the network has instructed a DRX application or a DRX release;
- and
- a resource calculator for selecting the CQI report resources associated with the CQI report resource information, after receiving the DRX state application signal by the signal transceiver.
An apparatus of a network for receiving Channel Quality Information (CQI) from a User Equipment (UE) in a wireless communication system, the apparatus comprising:
- a Discontinuous Reception (DRX) manager for selecting the UE to operate in a DRX state, the DRX state being a state where the UE discontinuously monitors a channel;
- and
- a signal transceiver for
- transmitting, to the UE, CQI report resource information,
- receiving, from the UE, first CQI according to the CQI report resource information in a continuous reception state, the continuous reception state being a state where the UE continuously monitors the channel,
- transmitting, to the UE, a DRX application signal indicating transition from the continuous reception state to the DRX state, and
- receiving, from the UE, second CQI based on CQI report resources associated with the CQI report resource information, after transmitting the DRX application signal.
