    摘要: A radio access network (RAN) may be providing, in a coverage area, at least two access channels that are available for use by any wireless communication devices (WCD). Thereafter, the RAN may detect that a threshold load exists in the coverage area and responsively reserve one of the access channels for use only by authorized WCDs. In turn, authorized WCDs in the coverage area may be configured to use the reserved access channel to transmit access probes to the RAN, while unauthorized WCDs in the coverage area may be configured to use only a generally-available access channel to transmit access probes to the RAN. In this way, the disclosed methods and corresponding devices may limit the occupancy on the reserved access channel and thereby increase the likelihood that authorized WCDs can successfully access the RAN over the reserved access channel when the coverage area becomes congested.

    摘要: Disclosed is a method and apparatus for helping to reduce latency that may arise from requesting retransmission of non-received packets. A device carrying out the method may be arranged to not send negative acknowledgements for non-received packets. Further, in an implementation where the device is to send for each packet of an incoming sequence either a positive acknowledgement indicating that the device received the packet or a negative acknowledgement indicating that the device did not receive the packet (and constituting a request for retransmission of the packet), the device will send for each packet a positive acknowledgement regardless of whether the device received the packet. The device will thus send a positive acknowledgement for at least one packet even though the device did not receive the packet.
