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.

The disclosed technology relates to interlacing wireless communication frames for use in communications between user equipments and base station in a wireless network.
In existing communication systems (legacy systems) such as an 802.16e system, a communication frame has a specified duration such as 5 ms. In the case of a system based on time division duplexing (TDD), the legacy communication frame (or simply “legacy frame”) is structured to be divided in time into a DL (downlink) portion and a UL (uplink) as illustrated in FIG. 1. In the legacy frame, guard periods TTG and RTG between the DL and UL portions serve as transition gaps to allow a user equipment of the wireless network to transition between receiving/transmitting signals (data and control) from/to a base station.
The structure of the legacy frame starts with a preamble which serves as a synchronization point for the communication between the base station and the user equipment. Also in the preamble, a cell identity is provided. That is, the cell identity within the preamble associates the legacy frame to a base station and sector.
The foregoing and other objects, features, and advantages of the invention will be apparent from the following more particular description of preferred embodiments as illustrated in the accompanying drawings in which reference characters refer to the same parts throughout the various views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.
FIG. 1 illustrates an example structure of a legacy communication frame;
FIG. 2 illustrates a structure of an example low-latency communication frame;
In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. That is, those skilled in the art will be able to devise various arrangements which, although not explicitly described or shown herein, embody the principles of the invention and are included within its spirit and scope.
In some instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. All statements herein reciting principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future, i.e., any elements developed that perform the same function, regardless of structure.
Thus, for example, it will be appreciated by those skilled in the art that block diagrams herein can represent conceptual views of illustrative circuitry embodying the principles of the technology. Similarly, it will be appreciated that any flow charts, state transition diagrams, pseudocode, and the like represent various processes which may be substantially represented in computer readable medium and so executed by a computer or processor, whether or not such computer or processor is explicitly shown.
