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: System and method embodiments are provided for pausing data transmission in a full-duplex wireless network. Embodiments eliminate the deadlocks in the full duplex MAC layer and improve the system efficiency. In an embodiment, a method in a wirelessly enabled and full duplex enabled network component for pausing an ongoing data transmission includes beginning a transmission, with the network component, of first data to a first station; determining, with the network component, that transmission of a second data to a second station is required before completion of the transmission of the first data to the first station; transmitting, with the network component, a pause indicator to the first station notifying the first station that transmission of the first data will be paused; transmitting, with the network component, the second data to the second station; and resuming transmitting, with the network component, the first data to the first station.

Abstract: Diverse traffic types can be efficiently communicated in a simultaneous manner by dynamically selecting between contention-based and scheduling-based media access control (MAC) communication schemes. Such a mechanism may be particularly beneficial in networks having a contention-based access resources and scheduling based access resources. Contention-based resources and scheduling based resources may occur over a common period, and may be orthogonal in the frequency domain and/or in the code domain. The dynamic selection may be based on a traffic characteristic or a network characteristic, and may be performed on a packet-by-packet basis. The selection criteria may be updated dynamically to adapt to changing network conditions, and may be communicated to the various transmitters via control channels or higher layer signaling.
