Abstract

A method is disclosed in which downlink control information transmitted by a radio access network provides an indication of at least one set of control resources configured at a UE, or of at least one search space configured at a UE, that the UE is to stop monitoring for DCI, start monitoring for DCI, or continue monitoring for DCI.

Claims (32)

1. A method performed by a user equipment (UE), the method comprising:

receiving, from an access network node, a Radio Resource Control (RRC) message including information indicating:

a slot unit G as a power of two;

a duration of consecutive slots T s ; and

a monitoring periodicity k s including the duration T s and an unmonitoring duration k s -T s ; and

monitoring a physical downlink control channel at monitoring slots determined per G slots during the consecutive slots T s of the duration.

2. The method according to claim 1 , wherein the G corresponds to one of a plurality of numerologies that is being used for communication of the UE.

3. The method according to claim 1 , wherein the higher G corresponds to the higher numerology.

4. Δ user equipment (UE), comprising:

a memory storing instructions; and

at least one processor configured to process the instructions to:

receive, from an access network node, a Radio Resource Control (RRC) message including information indicating:

a slot unit G as a power of two;

a duration of consecutive slots T s ; and

a monitoring periodicity k s including the duration T s and an unmonitoring duration k s -T s ; and

monitor a physical downlink control channel at monitoring slots determined per G slots during the consecutive slots T s of the duration.

5. The UE according to claim 4 , wherein the G corresponds to one of a plurality of numerologies that is being used for communication of the UE.

6. The UE according to claim 5 , wherein the higher G corresponds to the higher numerology.

7. A method performed by an access network node, the method comprising:

transmitting, to a user equipment (UE), a Radio Resource Control (RRC) message including information indicating:

a slot unit G as a power of two;

a duration of consecutive slots T s ; and

a monitoring periodicity k s including the duration T s and an unmonitoring duration k s -T s ; and

transmitting a physical downlink control channel at monitoring slots determined per G slots during the consecutive slots T s of the duration.

8. A radio access network node comprising:

a memory storing instructions; and

at least one processor configured to process the instructions to:

transmit, to a user equipment (UE), a Radio Resource Control (RRC) message including information indicating:

a slot unit G as a power of two;

a duration of consecutive slots T s ;

a monitoring periodicity k s including the duration T s and an unmonitoring duration k s -T s ; and

transmit a physical downlink control channel at monitoring slots determined per G slots during the consecutive slots T s of the duration.
