Systems and methods are disclosed that relate to handling of time-overlapped uplink transmissions in a cellular communications system. In one embodiment, a method performed by a user equipment (UE) comprises receiving a first timing advance and a second timing advance, receiving a request for a first uplink transmission according to the first timing advance, and receiving a request for a second uplink transmission according to the second timing advance, wherein the first uplink transmission and the second uplink transmission at least partially overlap in time. The method further comprises dropping at least part of the first uplink transmission or at least part of the second uplink transmission. In this manner, the possibility of collision of uplink transmissions (e.g., to multiple Transmission and Reception Points (TRPs)) may be reduced and thus the uplink resource utilization may be improved.
A method performed by a user equipment (UE), the method comprising:
-14. (canceled)
A user equipment (UE) adapted to:
-26. (canceled)
A method performed by network node for scheduling a first uplink transmission from User Equipment (UE) to a first Transmission and Reception Point (TRP) with a first timing advance in a first time slot and a second uplink transmission to a second TRP with a second timing advance in a second time slot, wherein the first and the second slots are adjacent slots, the method comprising:
-32. (canceled)
A network node for scheduling a first uplink transmission from User Equipment (UE) to a first Transmission and Reception Point (TRP) with a first timing advance in a first time slot and a second uplink transmission to a second TRP with a second timing advance in a second time slot, wherein the first and the second slots are adjacent slots, the network node adapted to:
-36. (canceled)
