Grant-less operations
First Claim
1. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to an access network via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:
- receiving an indication of one or more access allocations for grant-less transmissions;
selecting an access allocation of the one or more access allocations so as to define a selected access allocation;
determining a first transmit power level for a grant-less transmission;
transmitting, at the first transmit power level, an uplink message over the selected access allocation without requesting an uplink grant, so as to transmit a grant-less transmission;
determining whether to retransmit the uplink message; and
if the uplink message is retransmitted in a retransmission;
determining whether to switch to an uplink grant mode for the retransmission;
determining a second power level for the retransmission; and
making the retransmission at the second power level, using the uplink grant mode or a grant-less retransmission.

Abstract
Current approaches to transmitting uplink data in a network often require resources to be granted. In an example, a node or apparatus may configure a plurality of devices to operate in a grant-less mode in accordance with a respective grant-less access allocation. Grant-less operations may be managed, for example, to meet the reliability and latency requirements and battery life requirements for different types of devices. For example, the state transition between grant-less and grant based may be managed.

14. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a user equipment via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:
-
sending an indication of one or more access allocations for grant-less transmissions; sending synchronization signals and/or reference signals; receiving an uplink grant-less message over one of the one or more access allocations without sending an uplink grant, so as to receive an uplink grant-less message; determining a power level adjustment based on the received uplink grant-less message; determining whether to request for a retransmission of the uplink grant-less message; and if the uplink grant-less message is requested for retransmission; determining whether the retransmission should be in a grant mode; and sending a retransmission indication comprising the power level adjustment. - View Dependent Claims (15)

16. A method perform by a user equipment during grant-less operation, the method comprising:
-
receiving an indication of one or more access allocations for grant-less transmissions; selecting an access allocation of the one or more access allocations so as to define a selected access allocation; determining a first transmit power level for a grant-less transmission; transmitting, at the first transmit power level, an uplink message over the selected access allocation without requesting an uplink grant, so as to; determining whether to retransmit the uplink message; and if the uplink message is retransmitted in a retransmission; determining whether to switch to an uplink grant mode for the retransmission; determining a second power level for the retransmission; and making the retransmission at the second power level, using the uplink grant mode or a grant-less retransmission.
