Abstract: Aspects of the present disclosure provide for various methods and apparatuses for mitigating intra-cell interference when multiplexing grant-less traffic and grant-based traffic. When a wireless device transmits data without first requesting a grant of certain network resources from a base station, such data transmission may be called grant-less traffic in this disclosure. Different from grant-less traffic, when a wireless device needs to request a grant of certain network resources before transmitting data, such data may be called grant-based traffic in this disclosure.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication network may support mission critical (MiCr) communications and mobile broadband (MBB) communications with hybrid multiplexing (e.g., time division multiplexing (TDM) and frequency division multiplexing (FDM)). A base station may identify a first set of resources allocated for MiCr communications and a second set of resources allocated for MBB communications. The first and second set of resources may be multiplexed in the frequency domain, and the base station may transmit MiCr information over the first set of resources under normal data traffic conditions. As data traffic or other conditions associated with MiCr communications change, the base station may schedule MiCr transmissions on the second set of resources allocated for MBB communications, by puncturing the second set of resources for the MiCr communications.

Abstract: Methods, systems, and devices for wireless communication are described. A first cell may receive a message indicating that a second cell has a priority transmission scheduled using a transmit time interval (TTI) that is shorter than a TTI used by the first cell. The first cell may limit, based on the message, a communication parameter associated with communications between the first cell and a user equipment (UE) during the scheduled priority transmission.

Abstract: A first apparatus may send, to a base station, a set of channel quality indicators associated with a set of channels. The first apparatus may monitor sets of control channel elements in a search space based on the set of channel quality indicators sent to the base station. A second apparatus may receive, from a first user equipment, a set of channel quality indicators associated with a set of channels. The second apparatus may send, based on the set of channel quality indicators received from the first user equipment, control information on a physical downlink control channel associated with the first user equipment in a search space specific to the first user equipment.

Abstract: Methods, systems, and devices for wireless communications are described that support evolved semi-persistent scheduling (SPS) for wireless communications. A base station may configure SPS in which multiple time intervals are scheduled, each time interval including multiple slots that may be scheduled by different uplink or downlink resource allocations. The SPS configuration may include an ON-OFF duty cycle where an ON portion of the duty cycle spans a portion of a time interval and includes uplink and downlink resources, and an OFF portion of the duty cycle spans a remaining portion of the time interval and does not include any allocated SPS resources. Such SPS configurations may be used, for example, for transmitting sensor data and command information between controllers and sensors/actuators in a factory automation network.

Abstract: Aspects of the present disclosure provide methods for modifying the numerology of the D2D frame structure to match the numerology of the Macro cell communication frame structure. Particularly, the present disclosure introduces techniques that allow the D2D devices to partition a long-TTI D2D transmission into a plurality of segments such that each segment may fit into a short-TTI MiCr uplink (UL) subframe. The present disclosure also provides techniques for scheduling D2D transmission and managing transmission power of the D2D communication to minimize the interference with the MiCr communication on the macro cell while maximizing the spectrum utilization.

Abstract: Methods, systems, and devices for wireless communications are described for providing acknowledgements of grant-free uplink transmissions, which may in some cases be used for low latency communications. Approaches described herein include the use of per-user equipment (UE) acknowledgement resources assigned to UEs configured for grant-free uplink transmissions as well as the use of per-group acknowledgement resources assigned to groups of UEs configured for grant-free uplink transmissions. Dynamic puncturing of data in a shared downlink data channel may be used in the context of per-UE acknowledgement resource assignment. Corresponding grants of uplink transmission resources may be used in the context of per-group acknowledgement resources assignments.

Abstract: Various aspects of the disclosure relate to wireless communication that is synchronized across different wireless communication spectrum. For example, communication on an unlicensed spectrum may, in response to a particular trigger, switch to a licensed spectrum. Here, the switch may occur in a time synchronized manner (e.g., according to a frame structure). In addition, communication across such spectrum may be synchronized among multiple systems. For example, a controller may specify a reuse pattern to be used by the different systems for communication across unlicensed spectrum and licensed spectrum.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in a current mini-slot within an enhanced mobile broadband (eMBB) slot. A base station may determine that an indication message is to be transmitted within the eMBB slot. The indication message may indicate that at least a portion of the mini-slot of the eMBB slot is used for the URLLC transmission. The base station may allocate one or more resources to an indication channel in a same mini-slot as the portion of the mini-slot to be used for the URLLC transmission. The base station may transmit the indication message during the mini-slot on the indication channel using the allocated one or more resources. A UE may receive the indication channel and process at least the portion of the mini-slot based on whether the indication message is received.

Abstract: Methods, systems, and devices for wireless communication are described for SPS for low-latency communications. A wireless communication device may establish a block of semi-persistent scheduling (SPS) resources in each of a plurality of transmission time intervals (TTIs) for transmission of priority traffic, and determine that a level of priority traffic to transmit during a first TTI of the plurality of TTIs is below a priority traffic threshold. The wireless communication device may transmit a per-TTI release signal to indicate that the block of SPS resources in the first TTI is released from being reserved for priority traffic.
