Abstract:
Embodiments of wireless communication devices (WCDs) and methods for cancelling signal interference in the WCDs are generally described herein. Some of these embodiments describe a WCD that includes a receiver to generate a received signal, which includes at least a first signal transmitted to the WCD by a network station that operates in a full-duplex mode while the WCD operates in a half-duplex mode. The WCD also includes a module to generate an interference cancellation signal for the received signal based on interference information obtained from at least the received signal. The interference information is associated with a second signal transmitted to the network station by an additional device. The first signal is transmitted while the second signal is transmitted. The first and second signals include the same radio-frequency (RF) carrier.
Abstract:
This disclosure describes systems, methods, and computer-readable media related to employing rate adaptation in full-duplex communication. A first computing device may establish with a second computing device a full-duplex communication channel that may have a forward data transmission direction and a reverse data transmission direction. The first computing device may transmit to the second computing device a first data portion in the forward data transmission direction of the full-duplex communication channel at a default data transmission rate. The first computing device may receive a second data portion in the reverse direction of the full-duplex communication channel that may contain a forward channel quality information (CQI) associated with the forward data transmission direction. The first computing device may transmit to the second computing device a third data portion at a first data transmission rate, wherein the first data transmission rate is based at least in part on the forward CQI contained in the second data portion.
Abstract:
Various embodiments may be generally directed to resource allocation techniques for beam forming training. In one embodiment, for example, an apparatus may comprise logic for an access point (AP), at least a portion of the logic implemented in circuitry coupled to the memory, the logic to identify one or more resources available to support beamforming operations in a time interval, enable the AP to use the one or more resources in the time interval to interact with one or more allowed classes of station (STA) to perform one or more beamforming operations, and generate a frame for wireless transmission comprising a set of indicator bits encoded with an indication of the one or more resources. Other embodiments are described and claimed.

Abstract:
Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises baseband circuitry including one or more processors to decode a secondary synchronization signal (SSS) or a beam reference signal (BRS) received from an evolved Node B (eNB) to select a Tier-1 sector for receiving downlink transmissions from the eNB, decode a downlink control channel message received from the eNB at one or more fixed time offsets after the UE decodes the SSS to obtain index information for the Tier-1 sector to identify the Tier-1 sector, and if the Tier-1 sector has changed initiate a random access procedure to select an updated Tier-1 sector, and generate an updated Tier-1 sector index message to report to the eNB.
Abstract:
Apparatuses of a user equipment (UE), a cellular base station, and radio access network (RAN) nodes are disclosed. An apparatus of a wireless communication device includes circuitry configured to measure reference signals received from a plurality of antennas of an other wireless communication device, and circuitry configured to cause one or more antennas of the wireless communication device to transmit information regarding the received reference signals back to the other wireless communication device to enable the other wireless communication device to estimate a utility function for different transmit parameter sets.
Abstract:
Embodiments of a system and method for selecting a duplex mode for a service operating in a Wireless Network are generally described herein. In some embodiments, a mobile device may receive one or more traffic packets related to an establishment or a re-establishment of a service at the mobile device, and may select a duplex mode for the service. In some embodiments, the mobile device may be an IEEE 802.11 Station (STA). The mobile device may be configured to select full-duplex as the duplex mode when a delay requirement associated with the service is less than a predetermined delay threshold and when a calibration overhead associated with the mobile device or the service is less than a predetermined calibration overhead threshold. In addition, the mobile device may also be configured to select time-division duplex (TDD) or frequency-division duplex (FDD) as the duplex mode when the delay requirement is less than the delay threshold and when the calibration overhead is less than the calibration overhead threshold.

Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises one or more baseband processors to generate a first set of one or more radio resource control (RRC) messages to create a packet data convergence protocol (PDCP) and RRC entity at a donor Fifth Generation evolved NodeB (DgNB), and to generate a second set of one or more RRC messages to create a radio link control (RLC) entity at a serving relay node (RN) to couple with the DgNB in a multi-hop relay network, and a memory to store the first set of one or more RRC messages or the second set of one or more RRC messages.
Abstract:
A Spatial Multiple Access Uplink for Wireless LANs is generally described herein. A novel FD-MiMAC, protocol leverages full duplex functionality at the Access Point, can be incrementally deployed with current 802.11 Access Point and client devices, can be easily implemented by client devices in a distributed and contention based manner, and pairs users in uplink MU-MIMO to enhance system performance. A method for spatial multiple access uplink in a wireless local area network comprises announcing, by an Access Point (AP), its available remaining antenna capability, receiving, by the AP, a packet header frame transmitted by a winning client uplink contender, allocating, by the AP, uplink resources for the winning client uplink contender and immediately announcing its remaining antenna capability, and transmitting, by the AP, at the end of a winning client's transmission burst, an Acknowledge-to-All frame, whereby other clients may simultaneously restart contention for transmission of next frames.
