Abstract:
An apparatus and method for flexible adjustment of the uplink-downlink ratio configuration for each enhanced node B (eNodeB) within a wireless communications network is disclosed herein. In one embodiment, a given eNodeB is configured to determine a current or subsequent uplink-downlink ratio configuration for a pre-determined time period. The determined current or subsequent uplink-downlink ratio configuration is encoded into a special physical downlink control channel (PDCCH), the special PDCCH included in at least one radio frame according to the pre-determined time period. The radio frame including the special PDCCH is transmitted to user equipment served by the given eNodeB.
Abstract:
An integrated WLAN/WWAN Radio Access Technology (RAT) architecture is described in which signaling used to control the integration of the WLAN/WWAN architecture is performed over the Radio Resource Control (RRC) plane. The integrated architecture may allow for User Equipment (UE) assistance in cell selection and traffic steering. In particular, UE-assisted RRC signaling is described for managing inter-RAT session transfers and secondary cell (SCell) selection.

Embodiments of the present disclosure describe apparatuses and methods for signal designs for device-to-device (D2D) subframes. Various embodiments may include a UE with a radio transceiver to communicate with another UE via D2D communications. The UE may further include processing circuitry to generate a cyclic prefix (CP) for a first or second symbol of a D2D subframe at an orthogonal frequency division multiplexing (OFDM) resource block or a single-carrier frequency-division multiple access (SC-FDMA) resource block. Other embodiments may be described and/or claimed.

Abstract:
Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of precoded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.

Bidirectional iterative beam forming techniques are described. An apparatus may include a wireless device having an antenna control module operative to initiate beam formation operations using an iterative training scheme to form a pair of communications channels for a wireless network, the antenna control module to communicate training signals and feedback information with a peer device via the transceiver and phased antenna array using partially or fully formed high rate channels, and iteratively determine antenna-array weight vectors for a directional transmit beam pattern for the phased antenna array using feedback information from the peer device. Other embodiments are described and claimed.

Technology for mitigating edge effect interference in a Coordinated MultiPoint (CoMP) system having multiple CoMP clusters is disclosed. In an example, a method can include a macro node transmitting a cell range expansion request to user equipments (UEs) within a cell. A CoMP cluster for nodes within the cell that includes UEs operating with the cell range expansion can be generated. Blanked resources between a plurality of macro nodes for the CoMP clusters in the CoMP system can be coordinated using a muting preference including a blanked resource.

An integrated WLAN/WWAN architecture is described, in which signaling used to control the integration of the WLAN/WWAN architecture is performed over the Radio Resource Control (“RRC”) plane. The integrated architecture may provide a network-controlled framework for performing traffic steering and radio resource management. Additionally, according to the disclosure provided herein, the integrated architecture may interwork with legacy systems (e.g., architectures that do not support the integrated WLAN/WWAN architecture).
Abstract:
In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ratio transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT, another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.
