Abstract
An embodiment method for transmission adaptation includes sending, by an access point, to a UE, an indication of a configuration or a reconfiguration of at least one UE uplink transmission parameter for grant-free uplink transmissions, wherein the at least one UE uplink transmission parameter includes at least one of a transmission resource and a transmission scheme; and receiving, by the access point, a UE uplink packet transmission that includes at least one configured or reconfigured transmission parameter.
Claims30
A method comprising:
- receiving, by an apparatus from an access point, a second indication signal upon the apparatus transitioning from a Radio Resource Control (RRC) connected state to an RRC inactive state, the second indication signal being different from a previously configured first indication signal and indicating a second transmission scheme selected for the apparatus for grant-free packet uplink transmissions, the second transmission scheme being different from a first transmission scheme currently assigned to the apparatus for the grant-free packet uplink transmissions, wherein the first transmission scheme and the second transmission scheme each includes at least one of:
- a numerology specifying a subcarrier spacing;
- or
- a resource group for the grant-free packet uplink transmissions.

A method comprising:
- sending, by an access point to a user equipment (UE), a second indication signal upon the UE transitioning from a Radio Resource Control (RRC) connected state to an RRC inactive state, the second indication signal being different from a previously configured first indication signal and indicating a second transmission scheme selected for the UE for grant-free packet uplink transmissions, the second transmission scheme being different from a first transmission scheme currently assigned to the UE for the grant free packet uplink transmissions, wherein the first transmission scheme and the second transmission scheme each includes at least one of:
- a numerology specifying a subcarrier spacing;
- or
- a resource group for the grant-free packet uplink transmissions.
1 more element
An apparatus comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- receive, from an access point, a second indication signal upon the apparatus transitioning from a Radio Resource Control (RRC) connected state to an RRC inactive state, the second indication signal being different from a previously configured first indication signal and indicating a second transmission scheme selected for the apparatus for grant-free packet uplink transmissions, the second transmission scheme being different from a first transmission scheme currently assigned to the apparatus for the grant-free packet uplink transmissions, wherein the first transmission scheme and the second transmission scheme each includes at least one of:
- a numerology specifying a subcarrier spacing;
- or
- a resource group for the grant-free packet uplink transmissions.
