Abstract: Certain embodiments of the present disclosure propose a technique that may be utilized to accelerate the processing of MAC management messages by an MS, allowing the MS to return to a lower power state sooner, thereby conserving power. An indication of whether or not data bursts in a downlink (DL) sub-frame contain MAC management messages may allow the MS to avoid needlessly processing of data bursts and return to a low power state sooner.

Abstract: Certain embodiments of the present disclosure control whether or not certain protocol stack operation are performed in a hardware (HW) protocol stack accelerator based on ARQ/HARQ re-transmission rate. Latency penalties associated with using the HW accelerator are typically higher than the data movement overhead when this data does not need to be processed by the HW accelerator, such as when a re-transmission error occurs. According to certain embodiments, the HW accelerator is activated if the ARQ/HARQ re-transmission rate is below a threshold value. Otherwise, if the ARQ/HARQ re-transmission rate is above a threshold, at least a portion of the HW accelerator may be de-activated, which may reduce overhead associated with moving data between the protocol stack and the HW accelerator.

Abstract: Certain embodiments of the present disclosure improve a robustness of some critical MAC management response massages transmitted from a base station (BS) to a mobile station (MS). In this way, a reliability of transmission can be increased and a messaging failure that results in out of sync state between the MS and the BS can be avoided.

Abstract: In accordance with a method for implementing Short Message Service (SMS) in a WiMAX network, a mobile station may send a mobile station SMS request message to a base station. The mobile station SMS request message may include mobile-originated SMS data. In response, the base station may send a base station SMS response message back to the mobile station. For mobile-terminated SMS data, the base station may send a base station SMS request message to the mobile station. The base station SMS request message may include the mobile-terminated SMS data. In response, the mobile station may send a mobile station SMS response message to the base station. Ranging procedures and medium access control (MAC) management messages may be used to allocate bandwidth for the various messages.

Abstract: A mobile optical scanning device is proposed, which includes a power supply module, a contact image sensor (CIS) module, an application specific integrated circuit (ASIC) and a memory module. The power supply module acts as a power source for the scanning device. The scanning process can be activated by inputting a signal to the ASIC for activating a driving unit of the CIS module for scanning.

With the use of an input/output processing module of the ASIC being connected with an external host, the stored data in the memory module can be read. Since the scanning device is provided with the power source and memory, it can be used for scanning and storing data even in the condition of no hose being connected therewith.
