  • Publication number: 20180227047
    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.

  • Publication number: 20180184431
    Abstract: Methods, systems, and devices for wireless communication are described to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If the semi-persistent resources are not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in collisions between the scheduled traffic and the priority traffic.

  • Publication number: 20180184444
    Abstract: Methods, systems, and devices for wireless communication for adaptive ultra-reliable low-latency communications (URLLC) semi-persistent scheduling (SPS) are described. One method includes determining a data packet payload size for a transmission using SPS resources in a transmission time interval (TTI). The method also includes sending a release signal to release a portion of the SPS resources in the TTI based on the size and transmitting the data packet during the TTI using unreleased SPS resources. Another method includes identifying that a packet profile of packets transmitted on SPS resources varies by more than a packet profile threshold and sending, based at least in part on the identifying, a request-to-update (RTU) signal to update the SPS resources. The method also include receiving a confirmation of receipt of the RTU signal and updating a resource allocation or a resource attribute based at least in part on the packet profile and confirmation of receipt.

  • Publication number: 20180176747
    Abstract: Methods, systems, and devices for wireless communication are described. A first UE and a second UE may coordinate to establish a sidelink connection. The first UE may identify data to transmit to the second UE, and the first UE may transmit a request to send (RTS) message to the second UE with a first transmit power. The first UE may then determine to refrain from using the first transmit power for the data transmission, and the first UE may transmit the data to the second UE with a second transmit power that is different from the first transmit power. The UE may determine the second transmit power for the data transmission based on instantaneous channel quality information (CQI) received in a clear to send (CTS) message, a modulation and coding scheme (MCS) selected for the data transmission, a threshold power, etc.

  • Publication number: 20180176935
    Abstract: Techniques are described herein to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in interference between the scheduled traffic and the priority traffic communicated without first scheduling the specific communication resources. To mitigate interference between different traffic types, a user equipment (UE) may transmit a device-to-device silencing message to other UEs.

  • Publication number: 20180115380
    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.

  • Publication number: 20180115964
    Abstract: Various techniques provide for identifying and transmitting a first transmission to a UE in a first transmission time interval (TTI), and puncturing a portion of the first transmission with a higher priority second transmission that has a shorter TTI than the first TTI. The punctured portion of the first transmission may then be transmitted in a subsequent portion of the first TTI, concurrently with an originally allocated portion of the first transmission for that subsequent portion of the TTI. A UE may identify the punctured portion of the first transmission, and identify that the punctured portion of the first transmission is being transmitted in the subsequent portion of the first TTI. The UE may decode the received transmissions and merge the punctured portion with other, non-punctured, portions of the first transmission.
