Abstract:
Embodiments for providing virtual carrier sensing for LTE are generally described herein. In some embodiments, a first evolved Node B (eNB) sends a notification of subsequent DL transmission to a first UE in a downlink. In the uplink, the first UE sends a confirmation of the received DL notification. A second eNB overhears the confirmation, decodes it and extracts the information of the DL resources that the first eNB is planning to use. If the second eNB is not already transmitting in the indicated DL resources, the second eNB marks the indicated DL resources as busy and refrains from transmitting in those resources. The second eNB may then reschedule its transmission using alternative resources so that interference from the second eNB1 may be avoided.
Abstract:
Embodiments of the present disclosure describe systems and methods for mitigating interference in wireless networks. Various embodiments may include signaling of control channel information associated with an interfering cell and utilization of the control channel information to mitigate interference. Other embodiments may be described and/or claimed.
Abstract:
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for configuring coordinated multipoint (CoMP) for network devices. In various embodiments, configuration of the CoMP may be based on channel state information reference signals. Other embodiments may be described and/or claimed.
Abstract:
A user equipment (UE) power-cycles UE transmission modem components to reduce overall UE power consumption. For example, multiple HARQ ACK/NACK feedback bits are aggregated for a predetermined number of consecutive DL subframes, and then the feedback is transmitted in a single dedicated UL subframe so that a transmitter and power amplifier may be temporarily turned off (State 3) to reduce power consumption in the UE.
Abstract:
Embodiments of the present disclosure describe devices, methods, computer-readable media, and systems configurations for configuration of downlink coordinated multipoint (CoMP) communications in a wireless communication network. A user equipment (UE) may receive, from an evolved Node B (eNB), a radio resource control (RRC) transmission including channel state informations (CSI) reference signal (RS) parameters for a plurality of transmission points. The UE may subsequently receive a medium access control (MAC) control element (CE) including a plurality of index bits corresponding to one or more activated transmission points of the plurality of transmission points for which the feedback module is to generate CSI-RS feedback. The eNB may dynamically update the transmission points that are activated for CSI-RS feedback. The UE may receive another MAC CE from the eNB to notify the UE of the updated set of activated transmission points.
Abstract:
A cell-selection and a cell re-selection process include a wireless device that receives a signal from at least one node of a wireless network. The received signal can be a reference signal, an uplink signal, or a downlink signal, or a combination thereof. Location information of the wireless device is determined based on the received signal and transmitted to the wireless network. Information is received from the wireless network that contains a list of candidate nodes to which the wireless device can connect to the wireless network. The list of candidate nodes comprises a list of macro cell nodes, low-power cell nodes, or a combination thereof. The wireless device searches through the information containing the list of candidate nodes to determine a node for a connection to the wireless network.
Abstract:
Some demonstrative embodiments include apparatuses, systems and/or methods of wireless communication via an antenna array. For example, an apparatus may include an antenna array including a plurality of antenna modules arranged along a first axis, an antenna module of the antenna modules including an antenna sub-array coupled to a Radio-Frequency (RF) chain, the antenna sub-array including a plurality of antenna elements arranged along a second axis, the second axis is perpendicular to the first axis, and the RF chain is to process RF signals communicated via the plurality of antenna elements.
Abstract:
Embodiments of circuitry to be included in a user equipment (“UE”) and an evolved Node B (“eNB”) are described. To accelerate the detection of one or more cells in a wireless network, a UE may perform Radio Resource Management (“RRM”) measurements based on one or more synchronization signals instead of based on a common reference signal (“CRS”). Alternatively, the UE may perform RRM measurements for a cell based on a CRS transmitted for the cell without synchronizing to the cell using one or more synchronization signals. The UE may report the RRM measurements to an cNB that is to serve the UE.
Abstract:
Embodiments of methods and apparatus for wirelessly receiving, by a user equipment (UE), interference signal from a first enhanced Node B (eNB) while the UE is communicating with a second eNB; generating interference feedback information that is associated with an interference channel between the first eNB and the UE; and transmitting the interference feedback information to the first eNB via the second eNB are disclosed. Additional variants and embodiments are also disclosed.
Abstract:
Technology for periodic channel state information (CSI) reporting in a coordinated multipoint (CoMP) scenario is disclosed. One method can include a user equipment (UE) generating a plurality of CSI reports for transmission in a subframe for a plurality of CSI processes. Each CSI report can correspond to a CSI process with a CSIProcessIndex. The UE can drop CSI reports corresponding to CSI processes except a CSI process with a lowest CSIProcessIndex. The UE can transmit at least one CSI report for the CSI process to an evolved Node B (eNB).
