Abstract
A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode. In the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.
Claims26
A method performed by a communication device, the method comprising:
- receiving an uplink grant from a cellular network, the uplink grant indicating uplink radio resources allocated to the communication device in reoccurring time intervals;
- in response to receiving the uplink grant from the cellular network, sending a message to the cellular network, to acknowledge receipt of the uplink grant;
- and
- for each of the time intervals, selecting between:
- an active mode in which the communication device performs an uplink transmission in the allocated uplink radio resources, and
- an inactive mode in which the communication device performs no uplink transmission in the allocated uplink radio resources.
A method performed by a node of a cellular network, the method comprising:
- sending an uplink grant indicating uplink radio resources allocated to the communication device in reoccurring time intervals;
- resending the uplink grant, in response to not receiving an acknowledgment of the uplink grant from the communication device;
- and
- for each of the time intervals, the node selecting between:
- an active mode for receiving an uplink transmission from the communication device in the allocated uplink radio resources, and
- an inactive mode corresponding to no uplink transmission by the communication device in the allocated uplink radio resources.
A communication device comprising:
- an interface configured for wirelessly connecting to a cellular network;
- and
- at least one processor, the at least one processor configured to:
- receive an uplink grant from the cellular network, the uplink grant indicating uplink radio resources allocated to the communication device in reoccurring time intervals;
- in response to receiving the uplink grant from the cellular network, send a message to the cellular network, to acknowledge receipt of the uplink grant;
- and
- for each of the time intervals, select between:
- an active mode in which the communication device performs an uplink transmission in the allocated uplink radio resources, and
- an inactive mode in which the communication device performs no uplink transmission in the allocated uplink radio resources.
A node configured for operation in a cellular network, the node comprising:
- an interface configured for communicating with a communication device that is wirelessly connected to the cellular network;
- and
- at least one processor, the at least one processor configured to:
- send an uplink grant indicating uplink radio resources allocated to the communication device in reoccurring time intervals;
- resend the uplink grant in response to not receiving an acknowledgment of the uplink grant from the communication device;
- and
- for each of the time intervals, select between:
- an active mode for receiving an uplink transmission from the communication device in the allocated uplink radio resources, and
- an inactive mode corresponding to no uplink transmission by the communication device in the allocated uplink radio resources.
