Abstract: Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.

The access manager includes a user/group manager that manages the plurality of terminal stations in groups, and a radio resource manager that determines the necessity of bandwidth limit on the basis of the communication status of each of the groups and transmit from the access point a control message that allows communication of a particular group among the groups and stops communication of other groups when it is determined that the bandwidth limit is necessary.

Abstract: Electronic devices coupled to a network may exchange messages containing time-of-day information synchronization of the internal clocks. The information exchanged may include the instant at which a message leaves the electronic device. Discussed herein are methods and systems that allow 1-step timestamping of messages containing time-of-day information. The 1-step timestamping methods and systems may reduce the impact of non-deterministic time delays in the transmit path (e.g., encryption, expansion, inclusion of tags), and may improve the accuracy of the time-of-day information of the packets. For example, systems and methods may allow accurate 1-step timestamping of IEEE 1588 Precision Time Protocol packets with the uncertainty of delays from MACSec encryption or other security mechanisms. Some embodiments employ estimation non-deterministic delay of previously transmitted packets to estimate the state of the transmit path.
