Systems and methods for grant-free uplink transmissions
First Claim
1. A method for data transmission, comprising:
- selecting, by a network entity, a first type of uplink (UL) transmission resource assignment mechanism for a first user equipment (UE) for grant free transmission;
sending, by the network entity, a first type of UL transmission resource assignment to the first UE, wherein the first type of UL transmission resource assignment supports two types of signalling comprising radio resource control (RRC) signaling or a combination of a RRC signaling and dynamic signaling;
selecting, by the network entity, a second type of UL transmission resource assignment mechanism for a second UE for grant based transmission;
sending, by the network entity, a second type of UL transmission resource assignment for the second UE, the second type of UL transmission resource assignment supports dynamic signaling;
receiving, by the network entity, a first data using grant free transmission;
receiving, by the network entity, a second data using grant based transmission;
wherein the grant free transmission is a transmission mode without the network entity sending scheduling grant for the first type of UL transmission resource to the first UE; and
wherein the grant based transmission is a transmission mode with the network entity sending scheduling grant for the second type of UL transmission resource to the second UE.

Abstract
Systems and methods are disclosed for performing combined grant-free and grant-based UL resource allocation. In a particular embodiment, a network entity sends a first type of UL transmission resource assignment selected from two types of UL transmission resource assignment mechanisms to a UE for grant-free transmission and a second type of UL transmission resource assignment from two types of UL transmission resource assignment mechanism to a UE for grant based transmission. The network entity then receives a first data transmission from the UE for grant free transmission using an assigned transmission resource and a second data transmission from the UE for grant based transmission using an assigned transmission resources. Other embodiments pertain to changing the resource allocation scheme from grant free to grant based for a UE, or vice versa. Examples reasons for doing so may include HARQ re-transmisisons.
