Abstract: 単一周波数ネットワーク（ＳＦＮ）方式を用いて複数のセクタセルのすべて又は一部に対してＯＦＤＭ伝送により下りリンクの同一信号を送信するときに各セクタセルの全体にわたって受信レベルの低下を抑制するとともにマルチパス耐性の低下を抑制する無線装置を提供する。無線装置は、広域セルを構成する複数のセクタセルそれぞれの下りリンクでＯＦＤＭ伝送により送信される信号の全てまたは一部がセクタセル間で同一となるＳＦＮ方式を用いる。無線装置は、複数のセクタセルを形成し、各セクタセルに位置する端末装置に無線リンクを介して信号を送信し、互いに隣接するセクタセルの下りリンク信号の送信タイミングが同一とならないように且つ送信タイミング差を最小化するように、複数のセクタセルで繰り返される規則的な送信パターンで各セクタセルの下りリンク信号の送信タイミングを制御する。

Abstract: Embodiments of an Evolved Node-B (eNB) and methods for HARQ transmission are disclosed herein. The eNB may transmit, to a reduced-latency User Equipment (UE), an initial HARQ block and a diversity HARQ block for a reduced-latency data block. A sub-frame spacing between the transmissions of the HARQ blocks may be less than a sub-frame spacing used for transmissions of HARQ blocks to UEs not operating as reduced-latency UEs. The HARQ blocks for the reduced-latency data block may be transmitted in a reduced-latency region of time and frequency resources reserved for HARQ processes with reduced-latency UEs. In addition, HARQ blocks may be transmitted in time and frequency resources exclusive of the reduced-latency region to other UEs not operating as reduced-latency UEs.

Abstract: The disclosure is related to selectively patching frame erasures in a first stream. A receiver receives the first stream, receives a second stream corresponding to the first stream, detects a missing frame in the first stream, and attempts to replace the missing frame in the first stream with a corresponding frame from the second stream.

Abstract: Disclosed are methods, systems, and apparatus for maximizing the spectral efficiency of a communications spectrum by providing a means to transmit information continuously in both directions of a radio link on the same center frequency at any given time. One embodiment may be directed to a method of communicating in a point-to-point radio system. The method may include receiving a first signal at a first antenna of a radio head. The first signal may include a transmitted data signal and interfering signals. The method continues by determining a correction signal from a transmitter of the radio head and processing the first signal to remove the interfering signals using the correction signal, and sending a second signal using a second antenna. The first and second signals may be sent and received at substantially the same time.

Abstract: A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.

Abstract: A communication device and method of allocating spectrum resources in a communication system to protect data to be transmitted are disclosed. The communication channel resource is divided temporally to form regions. Data to be transmitted is separated into data portions. Each data portion is able to be transmitted over one of the regions. The data portions are prioritized based on the importance of the data portion. The regions are ranked based on the transmission reliability thereon. The prioritized data portions are mapped to the ranked regions such that more important data portions are mapped to more reliable regions and less important data portions are mapped to less reliable regions. The prioritized data is output temporally in order of importance to enable the mapping of the prioritized data.
