Abstract
Bandwidth parts (BWPs) and other resources for wireless communications are described. A wireless device may use a BWP control procedure and/or a BWP timer management procedure for activating, deactivating, and/or switching BWPs, for example, using multiple active BWPs. A base station may send information comprising one or more fields indicating an action associated with a BWP, for example, if multiple active BWPs are supported. A wireless device may control a first BWP inactivity timer associated with a first active BWP, for example, based on activating, deactivating, and/or switching a second BWP.
Claims24
A method comprising:
- receiving, by a wireless device, one or more messages indicating a first bandwidth part (BWP) of a cell and a second BWP of the cell;
- activating the first BWP as a primary active BWP of the cell;
- and
- based on receiving, via the first BWP, downlink control information (DCI) comprising a first field indicating the second BWP and a second field indicating activation of the second BWP as a secondary active BWP:
- activating the secondary active BWP of the cell while maintaining the first BWP as the primary active BWP.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive one or more messages indicating a first bandwidth part (BWP) of a cell and a second BWP of the cell;
- activate the first BWP as a primary active BWP of the cell;
- based on receiving, via the first BWP, downlink control information (DCI) comprising a first field indicating the second BWP and a second field indicating activation of the second BWP as a secondary active BWP:
- activate the secondary active BWP while maintaining the first BWP as the primary active BWP.
A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:
- receive one or more messages indicating a first bandwidth part (BWP) of a cell and a second BWP of the cell;
- activate the first BWP as a primary active BWP of the cell;
- based on receiving, via the first BWP, downlink control information (DCI) comprising a first field indicating the second BWP and a second field indicating activation of the second BWP as a secondary active BWP:
- activate the secondary active BWP while maintaining the first BWP as the primary active BWP.
