Systems, apparatuses, and methods for implementing real-time, low-latency packetization protocols for live compressed video data are disclosed. A wireless transmitter includes at least a codec and a media access control (MAC) layer unit. In order for the codec to communicate with the MAC layer unit, the codec encodes the compression ratio in a header embedded inside the encoded video stream. The MAC layer unit extracts the compression ratio from the header and determines a modulation coding scheme (MCS) for transferring the video stream based on the compression ratio. The MAC layer unit and the codec also implement a feedback loop such that the MAC layer unit can command the codec to adjust the compression ratio. Since the changes to the video might not be implemented immediately, the MAC layer unit relies on the header to determine when the video data is coming in with the requested compression ratio.

Real-time and low latency packetization protocol for live compressed video data

An approach is provided for data processing methods wherein a PHY layer transmit operation is constructed by aggregating MAC layer data units (MPDUs) by means of a linked list. A link list of TX descriptors can be formed separately from the payloads. In order to minimize processor speed rates, the next transmission buffer is pre-fetched whenever appropriate. Interlocks are used to prevent conflict on descriptor fetches and payload fetches.

Power management in wireless communications devices

An approach is provided for generating response frames. Incoming frames are processed by a receive controller to determine type and attributes. Based on the type and the attributes of the incoming frame, a response frame is constructed and transmitted by a transmit controller. A response frame is constructed by setting values in a frame template. A block ACK can be implemented by means of a block ACK scoreboard.

Hardware controlled receive response generation

Techniques for performing automatic antenna sector-level sweep switching are described herein. According to an embodiment, an apparatus comprises a lookup table for storing a set of antenna configuration entries and a sector-level sweep (SLS) controller implemented in hardware that is communicatively coupled to the lookup table. The SLS sweep controller is operative to read an antenna configuration entry from the set of antenna configuration entries stored in the lookup table and output control signals to configure a set of one or more antennas based on the antenna configuration entry. The SLS controller is further operative to switch between different antenna configuration entries in the set of antenna configuration entries stored in the lookup table in response to a signal from a timing source thereby periodically changing the configuration of the set of one or more antennas.

An integrated circuit comprises a main bus, one or more integrated processors, an external bus interface, memory, internal bus controller, a signal analyzer, timers, reset/clock generator, radio controller, optional data converters, and optional radio. The signal analyzer performs both time-domain and frequency-domain analysis of the input signal and supplies data to the one or more integrated processors for signal classification.

Integrated circuit for signal analysis

A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as 'sectors'. In one embodiment, channel allocation techniques for increasing one or more of throughput and coverage in a wireless communications environment. In one embodiment, a mode of operation is selected from a plurality of modes of operation, enabling a wireless communications transmitter to be dynamically configured to reach a wireless communications devices at a greater distance from the transmitter without increased interference between communications channels ('range mode') or to provide wireless communications to a greater number of wireless communications devices within a relatively closer distance to the wireless transmitter (&#x201c;capacity mode&#x201d;) or to provide wireless communications using a single channel to provide wireless communications at a relatively greatest distance from the transmitter (&#x201c;super range mode&#x201d;).
