Data rate justification circuitry adapted to control one or more communications between a physical layer device and a link layer device. In a first direction of communication, the data rate justification circuitry is configured to receive first virtual container data from the physical layer device over two or more asynchronous virtual container channels, and to synchronize the first virtual container data and aggregate the first virtual container data for transmission to the link layer device over a high data rate port.

Methods and apparatus for home node-b detection and measurements thereof
A method and apparatus for selecting or reselecting a home node-b (hnb), (i.e., a closed subscriber group (csg) cell), among cells having colliding physical layer signals are disclosed. Once the identity (id) of an hnb is determined, measurements needed to support cell selection or reselection are performed.

High performance interconnect physical layer
A periodic control window is embedded in a link layer data stream to be sent over a serial data link, where the control window is configured to provide physical layer information including information for use in initiating state transitions on the data link. The link layer data can be sent during a link transmitting state of the data link and the control window can interrupt the sending of flits.

High performance interconnect physical layer
A set of training sequences is generated, each training sequence to include a respective training sequence header, and the training sequence header is to be dc-balanced over the set of training sequences. The set of training sequences can be combined with electric ordered sets to form supersequences for use in such tasks as link adaptation, link state transitions, byte lock, deskew, and other tasks..
