Abstract: In an example method, a first device determines a first Zadoff-Chu sequence having a first root value, and a second Zadoff-Chu sequence having a second root value, where the first second root value is an inverse modulus of the first root value. Further, the first device generates a wireless signal including (i) a first preamble generated based, at least in part, on the first Zadoff-Chu sequence, (ii) a second preamble generated based, at least in part, on the second Zadoff-Chu sequence, and (iii) a payload. Further, the first device transmits the wireless signal from the first device to a second device.

Abstract: A user equipment device may determine whether to power down one or more components based at least on a scheduling parameter that includes an indication of cross-slot scheduling. The device may power down the one or more components prior to decoding control information during a slot for which the scheduling parameter indicates that cross-slot scheduling is in place.

Abstract: This disclosure relates to techniques for a wireless device to dynamically adapt its bandwidth use using network scheduling information in a cellular communication system. A radio resource control connection between a cellular base station and a wireless device may be established. The wireless device may receive network scheduling information from the cellular base station. The wireless device may dynamically select a receive bandwidth for receiving transmissions from the cellular base station based at least in part on the network scheduling information.

Abstract: This disclosure relates to performing cellular communication using a power efficient downlink control information framework. A wireless device and a cellular base station may exchange configuration information indicating that the cellular base station and the wireless device support a sleep downlink control information (sDCI) format. An sDCI configuration according to the sDCI format may be negotiated, including selecting at least one sDCI configuration parameter based at least in part on an application type currently associated with cellular communication between the cellular base station and the wireless device. Downlink control information may be provided during one or more subframes in accordance with the sDCI configuration. One or more subframes for which no downlink control information will be provided to the wireless device may be determined based at least in part on the sDCI configuration.

Abstract: Systems, methods, and circuitries are provided for supporting blind retransmission. In one example, a method includes processing control information that indicates resources for communication of a physical downlink shared channel or a physical uplink shared channel (PDSCH/PUSCH) transmission and timing information for a retransmission of the PDSCH/PUSCH. The method includes configuring operation to: receive the PDSCH/PUSCH transmission based on the resources; and determine that a subsequent PDSCH/PUSCH received at a subsequent time corresponds to the retransmission of the PDSCH/PUSCH when the subsequent time coincides with the indicated timing information for the retransmission and, in response combine the PDSCH/PUSCH with the retransmission in a HARQ buffer for decoding purposes.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for providing downlink control for non coherent joint transmission. A cellular base station may provide downlink control information associated with a non coherent joint transmission downlink data communication to a wireless device, which may receive the downlink control information. The downlink control information may be provided as a single downlink control information including scheduling information for two data streams of the non coherent joint transmission data communication, or a portion of a multi-stage downlink control information transmission. The wireless device may receive the non coherent joint transmission downlink data communication based at least in part on the downlink control information.
