Abstract
Wireless communications may comprise aperiodic transmission and reception. Control information may be associated with an aperiodic reference signal. A wireless device may be configured to use a first transmission control indicator (TCI) state of at least two TCI states to receive an aperiodic reference signal based on: a scheduling offset, and the aperiodic reference signal overlapping in time with a scheduled physical downlink shared channel (PDSCH).
Claims20
A method comprising:
- receiving, by a wireless device, downlink control information (DCI) associated with an aperiodic channel state information reference signal (CSI-RS);
- and
- receiving, using a first transmission configuration indicator (TCI) state of at least two TCI states, the aperiodic CSI-RS, wherein using the first TCI state is based on:
- a scheduling offset, between a last symbol of the DCI and a first symbol of the aperiodic CSI-RS, being less than a threshold;
- and
- the aperiodic CSI-RS overlapping in time with a scheduled physical downlink shared channel (PDSCH) transmission that is indicated with the at least two TCI states.
3 more elements
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) associated with an aperiodic channel state information reference signal (CSI-RS);
- and
- receive, using a first transmission configuration indicator (TCI) state of at least two TCI states, the aperiodic CSI-RS, wherein using the first TCI state is based on:
- a scheduling offset, between a last symbol of the DCI and a first symbol of the aperiodic CSI-RS, being less than a threshold;
- and
- the aperiodic CSI-RS overlapping in time with a scheduled physical downlink shared channel (PDSCH) transmission that is indicated with the at least two TCI states.
6 more elements
A system comprising:
- a wireless device;
- and
- a base station,
- wherein the base station is configured to:
- transmit, to the wireless device, downlink control information (DCI) associated with an aperiodic channel state information reference signal (CSI-RS);
- and
- wherein the wireless device is configured to:
- receive, using a first transmission configuration indicator (TCI) state of at least two TCI states, the aperiodic CSI-RS, wherein using the first TCI state is based on:
- a scheduling offset, between a last symbol of the DCI and a first symbol of the aperiodic CSI-RS, being less than a threshold;
- and
- the aperiodic CSI-RS overlapping in time with a scheduled physical downlink shared channel (PDSCH) transmission that is indicated with the at least two TCI states.
