Abstract
A method and apparatus for configuring a data subband in a wireless communication system is provided. A user equipment (UE) receives an indication of a data subband from a network, configures at least one data subband according to the indication, and performs communication with the network via the at least one data subband. One data subband consists of contiguous or noncontiguous physical resource blocks (PRBs).
Claims19
A method performed by a wireless device operating in a wireless communication system, the method comprising:
- receiving, from a network, a configuration of one or more data subbands;
- activating a first data subband among the one or more data subbands;
- communicating with the network in the first data subband;
- receiving, from the network, downlink control information (DCI) which includes information on a second data subband among the one or more data subbands;
- performing a bandwidth adaptation from the first data subband to the second data subband based on the information on the second data subband;
- activating the second data subband;
- and
- communicating with the network in the second data subband.
A wireless device operating in a wireless communication system, the wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably coupled 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, a configuration of one or more data subbands;
- activating a first data subband among the one or more data subbands;
- communicating, using the at least one transceiver, with the network in the first data subband;
- receiving, from the network using the at least one transceiver, downlink control information (DCI) which includes information on a second data subband among the one or more data subbands;
- performing a bandwidth adaptation from the first data subband to the second data subband based on the information on the second data subband;
- activating the second data subband;
- and
- communicating, using the at least one transceiver, with the network in the second data subband.
A processing apparatus configured to operate a wireless device in a wireless communication system, the processing apparatus comprising:
- at least one processor;
- and
- at least one memory operably coupled to the at least one processor,
- wherein the at least one processor is configured to perform operations comprising:
- obtaining a configuration of one or more data subbands;
- activating a first data subband among the one or more data subbands;
- controlling the wireless device to communicate with the network in the first data subband;
- obtaining downlink control information (DCI) which includes information on a second data subband among the one or more data subbands;
- performing a bandwidth adaptation from the first data subband to the second data subband based on the information on the second data subband;
- activating the second data subband;
- and
- controlling the wireless device to communicate with the network in the second data subband.
