Abstract: Systems and apparatus for assigning sub-bands to numerologies are provided. A system bandwidth is divided into bandwidth portions, and the bandwidth portions are used as the unit of assignment for assigning sub-bands to numerologies. Systems and methods are also provided for allocating resource blocks over a bandwidth such as a sub-band. The available bandwidth is divided into sub-band portions, and the bandwidth portions are used as the unit of allocation for allocating resource blocks to user equipment.

Abstract: Systems and methods of scheduling grant-based traffic and mapping resources for grant-free traffic are provided. Grant-based traffic is scheduled in a first frequency partition, and grant-free traffic is mapped in a second frequency partition. In a first option, grant-based traffic is also scheduled in part of the first partition, but in a limited manner that ensures a given device's transmission and retransmissions do not all experience interference with the grant-based traffic. In another option, some grant-free traffic is mapped to part of the second partition and is spread in frequency across the second partition.

Abstract: A system and method for wireless communications using resources allocated for different types of traffic that co-exist in the same transmission interval. In one embodiment, first data of a first type of traffic is scheduled in resources that are pre-reserved for a second type of traffic. Control signaling may be used to indicate whether the first type of traffic is scheduled in the resources pre-reserved for the second type of traffic.

Abstract: A method for uplink transmission by a UE includes obtaining information regarding a plurality of power control sets each having a plurality of power control parameters, wherein a value of at least one parameter in a first power control set is different from a value of the at least one parameter in a second power control set; obtaining information associating at least one of the power control sets with at least one operational property of the UE; and when at least one of the operational properties is in effect on the UE, transmitting a PUSCH using the parameters of the power control set associated with the at least one operational property in effect.

Abstract: Current HARQ procedures for grant-based uplink transmissions may not be suitable for implementations in which a UE can simultaneously transmit multiple transport blocks (TBs) to a base station. However, in some scenarios, such as in some grant-free uplink transmission schemes, a UE may simultaneously transmit multiple TBs. Systems and methods are disclosed herein for performing HARQ for situations in which a UE simultaneously transmits multiple TBs to a base station. By using the systems and methods described herein, HARQ may therefore be performed in such situations.

Abstract: A user equipment (UE) in a wireless communication system may be configured to use particular resources to send one or more uplink transmissions. However, sometimes during operation the particular resources the UE is configured to use are not well suited to the channel conditions at that time or result in interference or collision with other uplink transmissions. Systems and method are disclosed in which downlink control information (DCI) may be used to reconfigure one or more resources used by the UE for an uplink transmission. In some embodiments, resource reconfiguration instructions are sent by the base station along with hybrid automatic repeat request (HARQ) feedback. In some embodiments, a unified downlink signaling format is disclosed that may be used for UEs having different capabilities, with the bits of the unified downlink signaling relaying different instructions to different UEs depending upon the capability of the UE.

Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: Systems and methods of transmitting using different cyclic prefix types are provided. In some embodiments, the cyclic prefix type used changes on a per time interval based on characteristics of the traffic. In some embodiments, different cyclic prefix types are used simultaneously during a time interval for different traffic types.

Abstract: The time-frequency resources of a particular numerology may be used to transmit OFDM symbols that have a cyclic prefix that is longer than the cyclic prefix of other OFDM symbols. This may complicate alignment across different numerologies. Time-frequency resource partitions are disclosed herein that may assist in symbol alignment and/or subframe alignment across the different numerologies.
