Abstract: A user equipment (UE) for communication in a wireless network supporting inter-EUTRAN Node B (eNB) carrier aggregation has a receiver to communicate with a first eNB corresponding to a primary cell (PCell) in the wireless network and a second eNB corresponding to a secondary cell (SCell) in the wireless network. The receiver is configured to receive downlink data through a physical downlink shared channel (PDSCH) in the SCell. The UE has a processor configured to, in response to receiving the downlink data, generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SCell. A transmitter of the UE is configured to transmit, through a first physical uplink control channel (PUCCH) in the PCell, uplink control information (UCI) including the HARQ-ACK for the SCell.

Abstract: Apparatuses and methods for channel state information reference signal (CSI-RS) configuration in distributed remote radio head (RRH) systems are described. A transmission point selection module can receive a user equipment (UE) signal via a transmission point from a plurality of transmission points sharing a single cell identification. A downlink transmission point can be selected based on the UE signal. The UE can then be configured to report CSI-RS measurements for the selected downlink transmission point.

Abstract: Technology for device discovery using a device-to-device (D2D) sounding reference signal (SRS) and device discovery using D2D SRS in a channel measurement group (CMG) is disclosed. In an example, a user equipment (UE) configured for device discovery via a node using the D2D SRS can include a transceiver module. The transceiver module can send a radio resource control (RRC) device discovery request to a node, scan D2D SRS subframes of proximity UEs using D2D SRS triggering, and send feedback to the node of detected D2D SRS information of the proximity UEs. The proximity UE can be located within a same cell as the UE.

Abstract: The techniques introduced herein provide a framework for efficient communication to, and among, a local communication group (LCG). The LCG may be a peer-to-group communication or a network-to-group communication. The peer-to-group communication may be one way (e.g., one peer in the group may send communications to the rest of the users with little feedback) or two way (e.g., each member of the group may have the ability to share content with the remaining members of the group). According to the techniques introduced herein, local group communication may be anchored through an eNodeB of an LTE network, which may use a combination of multicast communications in the downlink and unicast communications in the uplink.

Abstract: Technology for enabling radio resource management (RRM) measurements in coordinated multi-point (CoMP) transmission and reception is disclosed. One method comprises sending, from an evolved node B (eNB) to a user equipment (UE), an information element (IE) containing a list of measurement objects that define configurations of channel state information reference signal (CSI-RS) based RRM measurements. The eNB can analyze the CSI-RS based RRM measurements in a CoMP Resource Management (CRM) Set, wherein each CSI-RS based RRM measurement corresponds to a transmission point in a set of transmission points which may be used for downlink transmissions to the UE. The eNB can select a CoMP Measurement Set based on the CSI-RS based RRM measurements reported by the UE, comprising at least one of the set of transmission points for which fast channel state information (CSI) feedback will be reported to the eNB from the UE.

One method comprises receiving, at an anchor serving cell in the HetNet, channel measurement reports made by a user equipment (UE) for a plurality of cells. A transmission point change request can be sent, based on the channel measurements for the UE, from the anchor serving cell to a target transmission point. The target transmission point is located in one of the plurality of cells. A transmission point change indicator is sent from the anchor cell to the UE to indicate a change in TP with which the UE will communicate via an air interface, while maintaining a connection to the anchor serving cell.

Abstract: An apparatus and method that allow user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A first D2D UE (dUE1) that wishes so communicate to a second D2D UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between the dUE1 and the dUE2. Among these requests are to make the D2D connection via WiFi instead of via Long Term Evolution (LTE). The eNB determines the WiFi capabilities of dUE1 and dUE2, then assigns a subset of available channels to be scanned by dUE1 and a separate subset of available channels to be scanned by dUE2. Thereafter, the eNB can assign a WiFi channel based on the scans performed by dUE1 and dUE2.

In some of these embodiments, the handover initiation parameters may include an offset value, such as an A3offset value, and a time-to-trigger (TTT) that comprise an A3offset-TTT pair.

Abstract: Technology is discussed for self-optimization approaches within wireless networks to optimize networks for energy efficiency, load capacity, and/or mobility, together with new, supporting channel state measurements and handover techniques. New, Channel State Information-Reference Signals (CSI-RSs) for yet-to-be-configured Cell-IDentifications (Cell-IDs) can be used to determine whether adjacent transmission cells can provide coverage for transmission cells that can be switched off for energy efficiency during formation of a Single Frequency Network (SFN). New approaches are also discussed to facilitate mobility within such a network. The new CSI-RSs and mobility approaches can also be used to split up such a SFN when changing load demands so require. Additionally, such new approaches can be used to create a SFN with a common Cell-ID where high mobility is required, such as near a roadway, and to break it up where high capacity is required, such as during a period of traffic congestion.
