Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.

Wireless device and method for rekeying with reduced packet loss for high-throughput wireless communications

Methods and apparatus relating to efficient and/or robust link power management of a UART (Universal Asynchronous Receiver/Transmitter) interface are described. In an embodiment, logic causes a link to enter into a low power consumption state in response to a message exchange over data lines of a UART (Universal Asynchronous Receiver/Transmitter) interface. The message exchange over the data lines of the UART interface is followed by a modification to one or more flow control signals coupled to the UART interface. Other embodiments are also disclosed.

Efficient power management of UART interface

Techniques are disclosed that dynamically allocate communications resources in a wireless communications network, such as a wireless personal area network (WPAN). For instance, a wireless communications device may obtain a resource allocation. This resource allocation includes a time slot (e.g., a TDMA time slot) within a wireless communications medium. The device determines a first portion of the time slot in which it intends to transmit data. Also, the wireless communications device relinquishes a second portion of the time slot that occurs after the first portion of the time slot. Based on this relinquishment, a central controller device may reallocate the second portion of the time slot.
