Support for transmission in preconfigured UL resources
Techniques for facilitating dedicated transmissions over preconfigured uplink resources. Embodiments include techniques to configure subsequent PUR resource utilization (e.g., one-at-a-time basis or on a periodic basis), changes to EDT signaling to allow functioning with PUR, etc. An example method performed by a wireless device configured for use in a wireless communication network includes transmitting ( 90 ), in an uplink message, a request for a configuration of preconfigured uplink resources. The method further includes receiving ( 100 ), during a connected mode in which the wireless device has a connection with the wireless communication network, control signaling indicating a first preconfigured resource configuration that configures a first preconfigured resource. The method also includes transmitting or receiving ( 120 ) user data using the first preconfigured resource.
