Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

Abstract: Systems and methods for UE state machine to support multiple services or air interfaces are described. The UE may have one configuration of the state machine for multiple services or air interfaces. The UE may have multiple state machines for different services or air interfaces that work independently. The UE may have multiple state machines for different services or air interfaces that work collaboratively. The UE may have a state machine that uses a state machine configuration selected out of a plurality of state machine configurations according to the services used. The configuration of this state machine may be adapted to services. At initialization, the configuration of this state machine may be default or be determined according to the services the UE may use. During operation, the configuration of this state machine may change according to the change in services for the UE.

Abstract: Aspects of the present disclosure enable the determination of beamforming information and channel information for communication between a transmitter and receiver by using a propagation path map. The propagation path map may provide an association between a location of the receiver and channel characteristics between the transmitter and the receiver via a direct propagation path and possible reflection propagation paths. The propagation path map may be used to obtain a more accurate location of the receiver, AoA at the transmitter and/or receiver, AoD at the transmitter, and/or receiver and other sensing information for beamforming and improving the RF propagation map. The association between a location of the receiver and channel characteristics between the transmitter and the receiver may then aid in performing beam measurements and/or channel measurements.

Abstract: Embodiments of the invention describe a novel solution to enhance network service to devices with limited or no connectivity. Embodiments include network-aware nodes deployed by an end-user or operator which are configured by a network to achieve enhanced coverage, enhanced throughput, enhanced battery life, and mitigation of cell boundary experiences, etc. Embodiments provide these benefits to a specified or non-specified set of user equipment (e.g., neighboring user equipment). The service expansion terminal can be an available user equipment that is idle and that has been volunteered, assigned, or is a dedicated node with limited user interface and designed for carrying out enhanced coverage, enhanced throughput, enhanced battery life, and the mitigation of cell boundary experiences, etc.
