    摘要： Methods of bandwidth utilization are provided. Within a scheduling bandwidth, which may be an entire carrier bandwidth or a sub-band, scheduling is used to reserve a guard zone at the edge of the scheduled bandwidth. This can be based on the frequency localization capabilities of a transmitter that is to be scheduled. The guard zone may be defined to a resolution that is the same as the scheduling resolution in which case the guard zone is defined entirely through scheduling. Alternatively, the guard zone may be defined to a resolution smaller than the scheduling resolution in which case scheduling and further signaling may be employed to define the guard zone.

    摘要： An apparatus and method for a wireless device to receive data in an eco state is provided. According to an embodiment of the disclosure, upon determining that data is to be transmitted to the wireless device in the eco state, a network node operates to transmit a unicast notification message to the wireless device in order to inform the wireless device of the impending data transmission. According to another embodiment of the disclosure, in response to receiving the unicast notification message, the wireless device operates to receive the data in accordance with the unicast notification message. To this end, the wireless device might for example try to receive data for a time period following the unicast notification message. Meanwhile, the wireless device may remain in the eco state.

    摘要： A system and method includes implementing, by a base station (BS), a reliable ultra-low latency transmission mechanism in a grant-free uplink transmission scheme having defined therein contention transmission unit (CTU) access regions and a plurality of CTUs. Implementing the reliable ultra-low latency transmission mechanism includes defining a reliable ultra-low latency CTU (RULL-CTU) access region from a portion of the CTU access regions of the grant-free transmission scheme, defining an RULL-CTU mapping scheme by mapping at least a portion of plurality of CTUs to the RULL-CTU access region to define a plurality of RULL-CTUs, defining a reliable ultra-low latency user equipment (RULL-UE) mapping scheme by defining rules for mapping a plurality of RULL-UEs to the plurality of RULL-CTUs in an initial pattern for initial transmissions in a first transmission time interval (TTI), and a regrouped pattern for redundant transmissions in a second TTI subsequent to the first TTI.
