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.

Management of MIMO communication systems

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.

Two-tier sector RF beamforming adaptation

Methods, apparatus, and computer-readable media are described to use multi-finger beamforming for multimeter wave communications. A base station associates with first and second user equipment. Weight sum rates are determined for the user equipment. Transmissions are scheduled to the user equipment based on the weight sum rates. Data is encoded for the first user equipment and transmitted based on the schedule. Data is encoded for the second user equipment and transmitted based on the schedule. The transmissions are multiplexed in the power domain.

Non-orthogonal multiple-access and multi-finger beamforming

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.

Advanced radio resource management in next-gen multi-hop relaying cellular network

An apparatus of a base station in a network may include a memory device and a processing device operatively coupled to the memory device. The processing device may process a message received at the base station from a macro-cell base station. The message may include a request to act as a relay for a user equipment (UE). The processing device may then determine that the base station is to act as a relay for the UE. The processing device may then generate a message comprising an indication that the base station accepted the request to act as a relay for the UE.

In-band full duplex relay to enhance uplink performance in heterogeneous network

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.

Resource allocation techniques for beamforming training

A client station (STA), when operating in a wireless network, receives data sent by an access point (AP) on a first channel comprising at least one subchannel. During reception of the data on the first channel, the STA monitors channel availability of an additional set of one or more subchannels. In response to a detected availability of at least one newly-available subchannel, the STA sends at least one notification to the AP identifying STA-side availability of the newly-available subchannel(s). The STA subsequently receives data from the AP on the newly-available subchannel(s), which is sent in response to the at least one notification. The AP, when communicating data to the STA, receives the at least one notification from the STA and, in response thereto, initiates data transmission on one or more of the newly-available channel(s).

Client-driven dynamic channel adaptation in wireless networking

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.

User station supporting a communication service and method for selecting duplex mode for the service

Techniques for presenting communication between two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for fast rate adaptation based on full duplex functionality, increasing link and network throughput. The present disclosure includes a method that provides a fast rate adaptation by leveraging full duplex in order to get immediate channel quality feedback.

Leveraging full duplex for rate adaptation in wireless LANs

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 having 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 containing a forward channel quality information (CQI) associated with the forward data transmission direction. The first computing device may transmit 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.

Systems and methods for rate adaptation in full-duplex wireless communication

Certain embodiments herein relate to scheduling interference between wireless devices in a manner that reduced interference associated with full duplex communication. Signal strength and interference information associated with communication between wireless devices may be collected and forwarded to a processing device, such as a central controller. The central controller may utilize such information to generate a conflict graph that depicts interference relationships between the wireless devices. Using the conflict graph, the central controller may determine whether requested communications may be scheduled along with concurrently scheduled communications without resulting in interference affecting the communications. In one embodiment, a requested communication may be scheduled with other concurrently scheduled communications if the aggregated throughput is increased with the addition of the requested communication.
