This invention relates to techniques for timing control in transmission or reception of data units in wireless communication. To better use the resources in a transceiver, a timing parameter is repeatedly initiated and reassigned. Depending on how the data units being handled, the timing parameter can be used to control a transceiver to retry transmission of data units or purge data units.

Method and apparatus for reliable data transmission and reception

This invention relates to techniques for managing a timer used in transmission or reception of data units in wireless communication. To better use the resources in a transceiver, one timer is used. Depending on how the data units being handled, the timer can be used to control a transceiver to retry transmission of data units or purge data units.

Timer management in wireless communication

This invention relates to techniques for managing the transmission and reception of data fragments that contains one or more data blocks. One embodiment of the invention includes the following steps: processing the fragments sequentially, wherein each fragment has a processing index that corresponds to sequential processing of that fragment; processing each of the fragments until a termination upon meeting at least one pre-defined condition; assigning a timer to an un-terminated fragment having a lowest processing index; starting said timer having a timeout value; and running said timer until the processing of said un-terminated fragment is terminated.

Techniques for processing data fragments in communication devices

This invention relates to techniques for managing the transmission and reception of data fragments that contains one or more data blocks using a single timer. One embodiment of the invention includes the following steps: processing the fragments sequentially, wherein each fragment has a processing index that corresponds to sequential processing of that fragment; processing each of the fragments until a termination upon meeting a first pre-defined condition; assigning a timer to an un-terminated fragment having a lowest processing index; starting said timer having a timeout value; and running said timer until the processing of said un-terminated fragment is terminated. This invention uses only one timer for each connection and therefore reduces memory and operational needs in the management of the data fragments that are being received or transmitted.

Techniques for managing the transmission and reception of data fragments

In one exemplary embodiment, a process for detecting a phone includes monitoring wirelessly transmitted traffic between first and second stations. Next, the process determines whether the traffic sent in both directions between the first and second stations are close to each other in term of traffic volume. The process identifies a total frames count of a number of frames of an identical frame size transmitted, where the number of frames is greater than any number of frames of a same size. The process calculates the percentage of the count that was just collected out of the count of the total frames. The process identifies the first station as a phone if the calculated percentage is over a first threshold and the total frames count is over a second threshold.

Methods to detect wireless stations in a wireless local area network

An information element including a hybrid acknowledgement map format and a method for using the hybrid acknowledgement format and information element are disclosed. The hybrid acknowledgement map comprises a type flag and a content block, and the value of the type flag indicates the format of the content block. This enables the hybrid acknowledgement map to represent data using multiple formats. The information element including a hybrid acknowledgement map includes a hybrid acknowledgement map and a hybrid quantity field indicating the number of hybrid acknowledgement maps in the information element. A field or multiple fields in the information element header indicate whether or not the information element includes a hybrid acknowledgement map. Information elements using hybrid acknowledgement maps contain more acknowledgment information which reduces transmission of information elements.

Hybrid acknowledgement map format for data communication networks

In one exemplary embodiment, voice quality of Voice over IP data in a wireless network is measured by first receiving at a detector in the wireless network a set of wireless frames transmitted between a first wireless device and a second wireless device in the wireless network in a predetermined time period. The wireless frames in the set carry Voice over Internet Protocol data. A rating value indicative of voice quality is determined based on the loss rate and burst rate that are determined only using frames received by the detection during monitoring.
