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 translation: 本公开的某些实施例基于ARQ / HARQ重传速率来控制是否在硬件（HW）协议栈加速器中执行某些协议栈操作。 当HW数据不需要由HW加速器处理时，例如当发生重传错误时，与使用HW加速器相关联的延迟处罚通常高于数据移动开销。 根据某些实施例，如果ARQ / HARQ重传率低于阈值，则HW加速器被激活。 否则，如果ARQ / HARQ重传速率高于阈值，那么硬件加速器的至少一部分可以被去激活，这可以减少与在协议栈和HW加速器之间的移动数据相关联的开销。

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: Methods and apparatus for conserving battery power in a mobile device for wireless communication by dynamically adjusting the clock frequency and/or the voltage of the device's processor according to the Media Access Control (MAC) layer state are provided. By using a higher clock frequency and/or a higher voltage for a normal operation state with large amounts of data traffic and lower clock frequencies and/or lower voltages for other MAC layer states (e.g., acquisition, network entry, and sleep/idle states), battery power may be conserved, thereby extending the time in which the device may operate between battery charging cycles.
