Abstract

Mechanisms to interlace multiple legacy frames to enhance radio resource utilization are described. Also described are mechanisms to modify a low-latency frame structure to appear as legacy frames. In one aspect, partially blanked-out legacy frames are interlaced with time offsets so that they complement each other to leave no idle system time. To a legacy user equipment, the interlaced frame appears as normal legacy frames used by multiple legacy cells. In another aspect, the low-latency frame is modified to appear as an interlaced frame. Again to the legacy user equipment, the low-latency frame appears as legacy frames from multiple legacy cells. To the low-latency user equipment, the modified low-latency frame still appear as normal low-latency frame. In this manner, radio resources of the legacy base stations are optimally utilized. Also, low-latency base stations are enabled to provide serves to the legacy user equipments without wasting radio resources.
