Abstract: A memory system includes a status circuit having a common status node electrically connected to a respective status pad of each of a plurality of memory chips. The memory system also includes a plurality of resistors disposed within the status circuit to define a voltage divider network for generating different voltage levels at the common status node. Each of the different voltage levels indicates a particular operational state combination of the plurality of memory chips. Also, each of the plurality of memory chips is either in a first operational state or a second operational state. Additionally, the different voltage levels are distributed within a voltage range extending from a power supply voltage level to a reference ground voltage level.

Abstract: A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station.

Abstract: Certain embodiments of the present disclosure provide techniques for bypassing the DCD/UCD message reception step in the network entry procedure in WiMAX systems by using DCD/UCD messages that are stored in a nonvolatile memory inside a mobile station.

Abstract: A subscriber station may receive a WiMAX connection identifier (CID) scheduling message from a 2G/3G network. The WiMAX CID scheduling message may include scheduling information that indicates when Multimedia Broadcast Multicast Service (MBMS) data for the subscriber station will be transmitted from a WiMAX network. The subscriber station may receive the MBMS data from the WiMAX network in accordance with the scheduling information.

Abstract: A base station (BS) may determine a fixed modulation scheme, a fixed PDU payload size, and a fixed number of PDUs per downlink burst for transmission of multicast data to subscriber stations. The BS may allocate downlink bursts to deliver the multicast data to the subscriber stations via PDUs using the fixed modulation scheme, the fixed PDU payload size, and the fixed number of PDUs per DL burst. A subscriber station (SS) may bypass the processing of multicast frames if the SS does not belong to any multicast groups. An SS may search for multicast connection identifiers (CIDs) in DL MAP IEs in multicast frames if the SS belongs to at least one multicast group. The SS may bypass the parsing of a PDU's MAC header within a corresponding downlink burst in the multicast frame in response to identifying a multicast CID in a DL-MAP IE in a multicast frame.

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: Techniques for an MS to establish one or more default service flows, after entering a WiMAX network are provided. The techniques presented herein may enable the MS to maintain said one or more default service flows during the sleep mode. The one or more default service flow may be utilized in quickly establishing a connection between a WiMAX BS and the MS following the sleep mode.

Abstract: By controlling whether operations are offloaded to a protocol stack hardware accelerator as a function of data rate, power consumption may be reduced, for example, when data rates result in fragmented or segmented data not suitable for processing by the stack hardware accelerator.

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 relate to methods for improving a service flow of a mobile device based upon a different level of its available battery power. If the battery power availability is below a predefined threshold, then one or more power-saving techniques can be triggered that increase an air time of the mobile device and provide savings of power consumption at different rates using a different level of clock rate.

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: A method for facilitating dynamic service-based system selection and determination may be implemented by a communications device. The method may include presenting system selection options to a user based on information that is received about Network Access Providers (NAPs) and Network Service Providers (NSPs). The method may also include receiving user input about the system selection options. The user may be permitted to provide input about specific services offered by specific NSPs. The method may also include determining user preferences regarding system selection based on the user input. The method may also include creating a preferred roaming list (PRL) based on the user preferences. The method may further include using the PRL to scan for available networks and channels and to find serving systems.

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.

As a result, the mobile device may receive the paging request regardless of which RAT it used for a current network connection.
