Abstract
A terminal device monitors an MPDCCH in a search space, and performs a DRX functionality for controlling monitoring of the MPDCCH. The search space including a first MPDCCH candidate and a second MPDCCH candidate, a beginning OFDM symbol in the first MPDCCH candidate being identical to a beginning OFDM symbol in the second MPDCCH candidate, and a repetition level of the first MPDCCH candidate being lower than a repetition level of the second MPDCCH candidate. When the MPDCCH detected in the first MPDCCH candidate indicates initial transmission, a drx-InactivityTimer in a last subframe in the second MPDCCH candidate is started or restarted.
Claims3
A terminal device comprising:
- reception circuitry configured to monitor a Machine type communication Physical Downlink Control Channel (MPDCCH) in a set of MPDCCH candidates;
- and
- medium access control layer processing circuitry configured to perform a DRX functionality for controlling monitoring of the MPDCCH, wherein
- the set includes a first MPDCCH candidate and a second MPDCCH candidate,
- a starting subframe among first subframes which include the first MPDCCH candidate is identical to a starting subframe among second subframes which include the second MPDCCH candidate,
- a repetition level of the first MPDCCH candidate is lower than a repetition level of the second MPDCCH candidate, and
- in a case that the MPDCCH detected in the first MPDCCH candidate indicates a new transmission, the medium access control layer processing circuitry starts or restarts a drx-InactivityTimer in a subframe following a last subframe among subframes including the MPDCCH.
A communication method used by a terminal device, the communication method comprising:
- monitoring a Machine type communication Physical Downlink Control Channel (MPDCCH) in a set of MPDCCH candidates;
- and
- performing a DRX functionality for controlling monitoring of the MPDCCH, wherein
- the set includes a first MPDCCH candidate and a second MPDCCH candidate,
- a starting subframe among first subframes which include the first MPDCCH candidate is identical to a starting subframe among second subframes which include the second MPDCCH candidate,
- a repetition level of the first MPDCCH candidate is lower than a repetition level of the second MPDCCH candidate,
- in a case that the MPDCCH detected in the first MPDCCH candidate indicates a new transmission, a drx-InactivityTimer is started or restarted in a subframe following a last subframe among subframes including the MPDCCH.
An integrated circuit mounted on a terminal device, the integrated circuit comprising:
- reception circuitry configured to monitor a Machine type communication Physical Downlink Control Channel (MPDCCH) in a set of MPDCCH candidates;
- and
- medium access control layer processing circuitty configured to perform a DRX functionality for controlling monitoring of the MPDCCH, wherein
- the set includes a first MPDCCH candidate and a second MPDCCH candidate, a starting subframe among first subframes which include the first MPDCCH candidate is identical to a starting subframe among second subframes which include the second MPDCCH candidate,
- a repetition level of the first MPDCCH candidate is lower than a repetition level of the second MPDCCH candidate, wherein
- in a case that the MPDCCH detected in the first MPDCCH candidate indicates a new transmission, the medium access control layer processing circuitry starts or restarts a drx-InactivityTimer in a subframe following a last subframe among subframes including the MPDCCH.
