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: In one embodiment, a method for adaptive transmission time intervals (TTIs) includes transmitting, by a communications controller to a user equipment (UE), a segment of a first TDD TTI configuration of a first TDD interval and a second TDD TTI configuration of the first TDD interval, where the first TDD TTI configuration has a first pattern, where the second TDD TTI configuration has a second pattern, where the first pattern is different than the second pattern, where the first TDD TTI configuration has a first uplink TTI segment and a first downlink TTI segment. The method also includes transmitting a first plurality of data on a first TTI in the first downlink TTI segment of the first TDD TTI configurations of the first TDD interval and receiving a second plurality of data on the first uplink segment of the first TDD TTI configuration of the first TDD interval.

Abstract: Systems and methods are provided that facilitate multiple switching points within a slot. A slot format indication is conveyed to a user equipment which indicates which symbols within a slot are uplink, downlink or unknown. Some formats feature half-slot switching meaning that a switch from uplink to downlink transmission takes place twice within a slot. Switching on a more frequent basis can deliver improved latency.

Abstract: Methods and devices that support multiple user equipment (UE) state configurations in a wireless network are provided. A state configuration is selected for a UE from among a plurality of candidate state configurations. Each candidate state configuration is associated with a respective set of one or more predefined operating states from among a plurality of predefined operating states. Information regarding the selected state configuration is then transmitted to the UE.

Abstract: When a user equipment (UE) is wirelessly communicating with a network, the wireless channel conditions may sometimes result in a low signal-to-noise ratio (SNR). The low SNR may be a result of the UE having poor geometry, e.g. the UE is at a cell edge. It is desired to increase the reliability of wireless communications in low SNR conditions. In some embodiments, less information may be dynamically signaled in the downlink control information (DCI), thereby allowing for a possibly lower effective coding rate.

Abstract: A New Radio (NR) control signal that indicates one or more Long Term Evolution (LTE) network parameters may be transmitted to NR UEs to enable the NR UEs to identify which resources carry LTE signal(s). The NR UEs may then receive one or more NR downlink signals over remaining resources in a set of resources without processing those resources that carry LTE signal(s). The NR downlink signals may have a zero power level, or otherwise be blanked, over resources that carry the LTE signal(s).

Abstract: Embodiments of this application provide a processing method for tracking a user equipment (UE) in a low power mode, and a device. The method includes: obtaining transmission configuration information between the UE and a network device, where the transmission configuration information indicates that an uplink tracking signal is to be sent according to a discontinuous transmission mode, and the transmission configuration information includes a transmission cycle. When the UE enters a low power mode, sending, an uplink tracking signal to the network device based on the transmission configuration information; and receiving timing advance (TA) adjustment information returned by the network device, where the TA adjustment information is obtained by the network device through detection of the uplink tracking signal.

Abstract: Different filtered-orthogonal frequency division multiplexing (f-OFDM) frame formats may be used to achieve the spectrum flexibility. F-OFDM waveforms are generated by applying a pulse shaping digital filter to an orthogonal frequency division multiplexed (OFDM) signal. Different frame formats may be used to carry different traffic types as well as to adapt to characteristics of the channel, transmitter, receiver, or serving cell. The different frame formats may utilize different sub-carrier (SC) spacings and/or cyclic prefix (CP) lengths. In some embodiments, the different frame formats also utilize different symbol durations and/or transmission time interval (TTI) lengths.
