Abstract: Some demonstrative embodiments include apparatuses, systems and method of disconnecting a wireless communication link. For example, a wireless communication device may include a controller to receive placement-related information indicating a change in one or more placement-related attributes of the wireless communication device, during communication over a wireless communication link, and based on the orientation-related information to disconnect the wireless communication link.

Abstract: Techniques to decode tail biting convolutional code are disclosed. A plurality of sets for a trellis may be determined. Each set may include a first stage and a second stage of the trellis. Path metrics for each state in a set may be determined when the first stage and the second stage have a same state. The path metrics may be compared to determine a state with a minimum path metric. Bits from the state with the minimum path metric may be output. Other embodiments are described and claimed.

Abstract: An apparatus may comprise a channel estimation architecture for wireless communications. Other embodiments are described and claimed.

Abstract: Some demonstrative embodiments include devices, systems and/or methods of link measurement of a wireless communication link. For example, a wireless communication unit may communicate a link measurement request frame between an initiator station and a responder station; may communicate a first link measurement report frame in response to the link measurement request frame, the link measurement report frame including link information determined by the responder station with respect to a wireless communication link between the initiator station and the responder station; and/or may communicate a second, unsolicited, link measurement report frame including link information determined by the initiator station with respect to the wireless communication link.

Abstract: A wireless network includes base stations and mobile stations. The base stations determine burst sizes and partitions, and signal this information to the mobile stations.

Abstract: Some demonstrative embodiments include devices, systems and/or methods of phase quantization. For example, a device may include a phase quantizer to receive a plurality of non-quantized phase values corresponding to a plurality of antenna elements of a phased-array antenna, based on the plurality of non-quantized phase values to select a predefined rotation angle, to determine a plurality of rotated non-quantized phase values by rotating the plurality of non-quantized phase values by the selected rotation angle, and to generate a plurality of quantized phase values by quantizing the plurality of rotated non-quantized phase values.

Abstract: An embodiment of the present invention provides a method of efficiently storing metrics for Hybrid Automatic Retransmission Request (HARQ) combining and enabling saving of memory buffer in communication systems, comprising using non-linear quantization of the metrics and managing an aggregated buffer for all HARQ channels.

Abstract: A method and system for receiving and decoding horizontally encoded MIMO-OFDM transmissions with improved efficiency. In one embodiment, MIMO decoding is performed on each of the extracted separate tones of a MIMO-OFDM signal to extract and demodulate frequency domain symbols of the first layer corresponding to one or more code blocks. For each code block of the first layer that passes an error check, corresponding portions of the second layer are decoded using SIMO decoding.

Abstract: An embodiment of the present invention provides an apparatus, comprising a transceiver configured for OFDM transmissions in frequency-contiguous, hopping, sub-channels.

Abstract: A single format of MAC control message may be used for the addition, deletion, or rearrangement of users in a group within a wireless network. In some cases, a change in the nature of the group may be implemented immediately upon receipt of a positive acknowledgement. A mobile station may determine its ACID without maintaining information about the previous ACID or startup frame.

Abstract: Briefly, in accordance with one or more embodiments, a data packet to be transmitted is encoded and one or more subpackets are generated from the encoded data packet. A first bit pattern is applied to a first symbol of the subpackets to provide a constellation, and a different bit pattern is applied to a next adjacent symbol in the constellation for one or more additional symbols. The data packet is then modulated according to the constellation and transmitted one or more times until the data packet is decoded by a receiver or until said transmitting is aborted according to a hybrid automatic repeat request error correction technique.

Abstract: Embodiments of the present disclosure describe orthogonal frequency division multiple access (OFDMA) transmissions using a plurality of antennas and/or transmit chains. Still other embodiments may be described and claimed.
