Abstract
A wireless device may receive downlink control information (DCI) indicating switching from a first bandwidth part to a second bandwidth part at a switching time. The wireless device may switch, based on the DCI and at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part. The wireless device may ignore, in response to the switching time being earlier than a transmission time indicated by an uplink grant, the uplink grant for the first bandwidth part.
Claims20
A method comprising:
- receiving, by a wireless device, downlink control information (DCI) indicating switching from a first bandwidth part to a second bandwidth part at a switching time;
- switching, based on the DCI and at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part;
- and
- ignoring, in response to the switching time being earlier than a transmission time indicated by an uplink grant, the uplink grant for the first bandwidth part.

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 downlink control information (DCI) indicating switching from a first bandwidth part to a second bandwidth part at a switching time;
- switch, based on the DCI and at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part;
- and
- ignore, in response to the switching time being earlier than a transmission time indicated by an uplink grant, the uplink grant for the first bandwidth part.
4 more elements
A system comprising:
- a base station comprising one or more first processors and first memory storing instructions that, when executed by the one or more first processors, cause the base station to:
- transmit downlink control information (DCI) indicating switching from a first bandwidth part to a second bandwidth part at a switching time;
- and
- a wireless device comprising one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive the DCI;
- switch, based on the DCI and at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part;
- and
- ignore, in response to the switching time being earlier than a transmission time indicated by an uplink grant, the uplink grant for the first bandwidth part.
