摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus preserves a state of a UE in an anchor eNB, wherein the anchor eNB is one of a set of connected cells, the UE being in a connected mode. Each cell of the connected set has a corresponding coverage area. The apparatus then maintains the state of the UE in the anchor eNB when the UE moves from a coverage area of the anchor eNB to a coverage area of another one of the cells from the set of connected cells.

摘要： Techniques for random access channel signaling on a shared communication medium are disclosed. A broadcast message including information associated with a Physical Random Access Channel (PRACH) may be transmitted and received on one or more subframes in a portion configured for downlink signaling. The broadcast message may comprise a contention type indicator, a timing advance indicator, or a combination thereof. The contention type indicator may indicate whether contention is in effect for transmission on the PRACH. The timing advance indicator may indicate whether an uplink transmission offset is in effect for transmission on the PRACH. Signaling over the PRACH may be transmitted and received on one or more subframes in a portion configured for uplink signaling.

摘要： Techniques for indicating and determining a subframe timing of an access point on a shared communication medium are disclosed. A method of transmitting a discovery reference signal (DRS) may include establishing a transmission timing for transmission of the DRS relative to a system timing of an access point, determining whether to transmit the DRS during a particular SF based on the selected DRS transmission window, and transmitting the DRS to at least one access terminal during the particular SF in response to a determination to transmit the DRS.

摘要： Disclosed are techniques for accessing a shared communication medium. An aspect includes communicating over the shared communication medium in accordance with a Time Division Duplexing (TDD) frame structure defining a set of downlink subframes and a set of uplink subframes, each uplink subframe being divided into a transmission gap period, a contention-exempt period, and a contention-compliant period, performing a contention procedure for contending for access to the shared communication medium during the transmission gap period, selectively transmitting contention-compliant uplink control signals during the contention-compliant period, and transmitting one or more contention-exempt uplink control signals during the contention-exempt period. An aspect includes receiving a downlink subframe of the shared communication medium and transmitting an acknowledgment of the downlink subframe during an uplink subframe of the shared communication medium, the uplink subframe occurring at least a predetermined number of subframes and/or at least a predetermined amount of time after the downlink subframe.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in connection with classifying devices that communicate with a femto node for providing services thereto. In one example, a node is equipped to monitor and/or receive one or more parameters communicated by a device, assign a classification to the device related to a frequency of using the femto node based in part on the one or more parameters. In an aspect, the node is equipped to provide services to the device based on the classification. In another aspect, the node is equipped to provide the classification to one or more femto nodes, including the femto node, for providing services to the device.

摘要： Femto node radio frequency channel selection may be achieved by selecting between a first band of operating channels and a second band of operating channels for a femto node based on at least one band-selection criterion, the first band including a plurality of channels that are higher in frequency than a plurality of channels in the second band, and configuring the femto node for operation according to one or more operating channels in the selected band.

摘要： A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.
