Abstract
A wireless device receives configuration parameters indicating PDCCH skipping durations. The wireless device may receive a DCI indicating PDCCH monitoring skipping for a first duration of the durations. The wireless device may transmit a random access preamble. The wireless device may ignore the PDCCH monitoring skipping and may monitor the PDCCH during a random access response window in response to transmitting the random access preamble.
Claims20
A method comprising:
- receiving, by a wireless device, configuration parameters indicating:
- a plurality of durations of downlink control channel skipping comprising a first duration;
- a length of a time window during which control channel monitoring skipping is ignored;
- and
- an offset from a random access message to the beginning of the time window;
- receiving a downlink control information:
- comprising a field with a first value indicating the first duration in the plurality of durations;
- and
- indicating skipping downlink control channel monitoring for the first duration;
- initiating a random access process comprising transmitting the random access message;
- ignoring the downlink control channel monitoring skipping and monitoring a downlink control channel during the time window with the configured length and starting in a second timing that is the offset after a first timing of the random access message;
- and
- receiving a random access response based on monitoring the downlink control channel during the time window.

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 configuration parameters indicating:
- a plurality of durations of downlink control channel skipping comprising a first duration;
- a length of a time window during which control channel monitoring skipping is ignored;
- and
- an offset from a random access message to the beginning of the time window;
- receive a downlink control information:
- comprising a field with a first value indicating the first duration in the plurality of durations;
- and
- indicating skipping downlink control channel monitoring for the first duration;
- initiate a random access process comprising transmitting the random access message;
- ignore the downlink control channel monitoring skipping and monitor a downlink control channel during the time window with the configured length and starting in a second timing that is the offset after a first timing the random access message;
- and
- receive a random access response based on monitoring the downlink control channel during the time window.
