UPLINK CHANNEL SELECTION USING CHANNEL INTERFERENCE TOLERANCE LEVEL FEEDBACK FOR GRANTLESS DATA TRANSMISSION
First Claim
1. A method of operating a scheduling entity in a wireless communication network, the method comprising:
- determining interference tolerance information of a plurality of uplink channels, wherein the interference tolerance information is configured to individually indicate an availability of each of the plurality of uplink channels for grantless uplink data transmission;
broadcasting the interference tolerance information to one or more subordinate entities; and
receiving a grantless uplink data transmission from the one or more subordinate entities utilizing one or more of the plurality of uplink channels according to the interference tolerance information.

Abstract
Aspects of the present disclosure provide for a network assisted grantless data transmission method operable in a wireless communication network. A wireless device may transmit grantless data without requesting a scheduling entity to grant and schedule network resources prior to the grantless data transmission. A scheduling entity determines interference tolerance information of a plurality of uplink channels, wherein the interference tolerance information is configured to individually indicate an availability of each of the plurality of uplink channels for grantless uplink data transmission. The scheduling entity broadcasts the interference tolerance information to one or more subordinate entities or wireless devices.
