Briefly, in accordance with one or more embodiments, mobile station or user equipment receives pilot signals from two or more infrastructure nodes in a distributed antenna system, and calculates phase or timing information, or combinations thereof, from the pilot signals. The mobile station feeds back the phase or timing information, or combinations thereof, to the infrastructure nodes, and then receives one or more subsequent transmissions from the infrastructure nodes with phase shift or timing adjustments, or combinations thereof, calculated by the infrastructure nodes and applied to the spatial streams transmitted by the infrastructure nodes.

Technology for communicating enhanced physical downlink control channels (ePDCCHs) configured for inter-cell interference coordination (ICIC) for a plurality of cells in a physical resource block (PRB) is disclosed. One method can include a node mapping a serving cell control channel element (CCE) in an serving cell ePDCCH in a PRB and a coordination cell CCE in a coordination cell ePDCCH in the PRB. The node can transmit the map of the serving cell CCE and the coordination cell CCE to a wireless device.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for configuration of downlink coordinated multi-point (CoMP) communications in a wireless communication network. A user equipment (UE) may receive channel state information (CSI) reference signal (RS) parameters, from an evolved Node B (eNB), for individual transmission points of a coordinated multi-point (CoMP) Measurement Set including a plurality of transmission points. The UE may generate CSI-RS feedback information for the individual transmission points of the CoMP Measurement Set, and may transmit the generated CSI-RS feedback information for one or more of the individual transmission points to the eNB. The UE may receive a transmission from the eNB updating the individual transmission points included in the CoMP Measurement Set.

Technology for performing multiple timing advances in a carrier aggregation communication system is disclosed. A method comprises communicating a random access preamble from a UE to an eNodeB via a PCell associated with a selected component carrier of the carrier aggregation. A Random Access Response (RAR) is received at the UE from the eNodeB for the PCell. The RAR contains a timing advance adjustment instructing the UE to adjust a timing of a PCell wireless communication. A request is received at the UE to adjust a timing of an SCell communication. A random access preamble is communicated to the UE via the SCell. An RAR is received at the UE from the eNodeB for the SCell to adjust a timing advance of the SCell wireless communication.

Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.

Briefly, in accordance with one or more embodiments, two or more cells are configured to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC). Measurement information is received from the one or more user equipment devices. One or more of the cells may be deactivated, or one or more additional cells may be activated for coordinated multipoint transmission based at least in part on the measurement information.
摘要:
Technology for forming carrier aggregation timing advance groups in a heterogeneous network (HetNet) is disclosed. One method comprises assigning at least a first component carrier cell to one of a first timing advance group and a second timing advance group. At least a second component carrier cell is assigned to one of the first timing advance group and the second timing advance group. A separate timing advance index value is selected for each of the first and second timing advance groups. The timing advance index value is used to refer to the timing advance group in signaling in the HetNet.
摘要:
Embodiments herein describe apparatuses, systems, and methods for signaling to support downlink coordinated multipoint (CoMP) communications with a user equipment (UE) in a wireless communication network. In embodiments, the UE may be configured with a plurality of channel state information (CSI) processes (e.g., via radio resource control (RRC) signaling) to use for providing CSI feedback to an evolved Node B (eNB) to support downlink CoMP communications. The UE may be configured with a plurality of sets of CSI processes. The UE may further receive a downlink control information (DCI) message from the eNB that indicates one of the configured sets of CSI processes on which the UE is to provide CSI feedback to the UE. The UE may generate the CSI feedback for the indicated set of CSI processes, and transmit the CSI feedback to the eNB in a CSI report.
