Abstract
A method, system and apparatus are disclosed. In one or more embodiments, a network node configured to communicate with a wireless device (WD) is provided. The network node is configured to, and/or comprises a radio interface and/or comprises processing circuitry configured to signal switching information for Bandwidth Part (BWP) switching in a search space that is absent scheduling information for data transmission to the wireless device.
Claims12
A network node configured to communicate with a wireless device, the network node comprising:
- processing circuitry configured to cause signaling of switching information for Bandwidth Part (BWP) switching to the wireless device, the signaling of switching information being absent of shared channel scheduling information, and the signaling of switching information pre-configuring the wireless device for the BWP switching such that the wireless device responsively switches from an active BWP to a specified BWP other than a default BWP at least (i) after having successfully completed a physical downlink shared control channel, PDCSH, reception, or (ii) having successfully completed a physical uplink control channel, PUCCH, transmission.
A wireless device configured to communicate with a network node, the wireless device comprising:
- processing circuitry configured to:
- receive signaling of switching information for Bandwidth Part (BWP) switching from the network node, the signaling of switching information being absent of shared channel scheduling information, and the signaling of switching information pre-configuring the wireless device for the BWP switching such that the wireless device responsively switches from an active BWP to a specified BWP other than a default BWP at least (i) after having successfully completed a physical downlink shared control channel, PDCSH, reception, or (ii) having successfully completed a physical uplink control channel, PUCCH, transmission;
- and
- perform the BWP switching based at least in part on the switching information.
A method implemented by a network node that is configured to communicate with a wireless device, the method comprising causing signaling of switching information for Bandwidth Part (BWP) switching to the wireless device, the signaling of switching information being absent of shared channel scheduling information, and the signaling of switching information pre-configuring the wireless device for the BWP switching such that the wireless device responsively switches from an active BWP to a specified BWP other than a default BWP at least (i) after having successfully completed a physical downlink shared control channel, PDCSH, reception, or (ii) having successfully completed a physical uplink control channel, PUCCH, transmission.
