摘要： Techniques for sending packets and maintaining synchronization during handover is described. A user equipment (UE) may be handed over from a source base station to a target base station. The source base station may forward packets for the UE to the target base station, which may receive the packets out of order. In one design, the target base station may determine whether each packet can be sent in order to the UE, send the packet if it can be sent in order, and discard the packet otherwise. In another design, the target base station may re-order packets received within a re-ordering window and may send the re-ordered packets to the UE. In yet another design, the target base station may process each packet received out of order as if the packet is in order, e.g., by incrementing a hyper-frame number (HFN) or re-assigning the packet with a later sequence number.

摘要： Systems and methodologies are described that facilitate processing service data units (SDU) in-order during communication handover in wireless networks. In particular, for mobile devices using re-transmission schemes, SDUs can be processed in-order by indicating to a target base station an index of a last SDU received in-order before handing off communication to the target base station. Additionally, SDUs received subsequent to one or more non-acknowledged SDUs can be forwarded to the target base station. Utilizing this information, the target base station can determine one or more SDUs the mobile device is preparing to re-transmit and can wait for this SDU before processing subsequently received SDUs. Also, a timer can be utilized to end a waiting period for the SDU.

摘要： Systems and methods are provided for a learning-based determination of semi-persistent scheduling of data-packet flow wireless communication. A packetized data flow served to a wireless terminal is fully scheduled for an initial period of time in order to collect statistics associated with scheduled packet sizes (Ss) and inter-packet times (Ts). Analysis of a cumulative distribution of {S, T} pairs indicate whether a characteristic packet size (S0) and size dispersion (D0) are associated with the cumulative distribution. Inter-time intervals associated with the characteristic size and dispersion complete a transport format. Semi-persistent scheduling is utilized for a packetized flow when a characteristic transport format can be extracted, or learned, from the accumulated statistics. Extracted transport formats can be employed to optimize scheduling efficiency upon handover.

摘要： A data packet communication system employs radio link control (RLC) transmission between a transmitter and a receiver with an Automatic Repeat Request (ARQ) arrangement whereby polling of the receiver is accomplished with reduced amount of redundantly transmitted data, such as between an access node and terminal. Upon a polling event, such as emptying of a transmission buffer of the transmitter, expiration of a polling timer, or reaching a radio link control (RLC) protocol data units (PDUs) count threshold, the transmitter sends a polling command to the receiver. This polling command is smaller than any of the RLC PDUs by resegmenting to a variably sized PDU sending a reduced amount of data. With evolving communication standards tending toward larger PDUs, such as in excess of a kilobyte for HSPA+ (High-Speed Packet Access Evolution) and 3GPP LTE (Long Term Evolution), this inefficiency can be of increasing impact.
摘要翻译：数据分组通信系统采用具有自动重传请求（ARQ）布置的发射机和接收机之间的无线电链路控制（RLC）传输，从而以减少量的冗余传输数据（例如接入节点和终奌站。在诸如排空发射机的传输缓冲器，轮询定时器到期或达到无线电链路控制（RLC）协议数据单元（PDU）计数阈值）的轮询事件之后，发射机向接收机发送轮询命令。该轮询命令比任何一个RLC PDU小，通过重新分组到发送减少的数据量的可变大小的PDU。随着不断变化的通信标准趋向于更大的PDU，例如超过一千字节的HSPA +（高速分组接入演进）和3GPP LTE（长期演进）），这种低效率可能会产生越来越大的影响。

摘要： Techniques for improving power saving by stations in wireless networks are described. In an aspect, a source station sends a frame with a buffer status for a recipient station during an awake time for both stations and sends one or more data frames to the recipient station as indicated by the buffer status. The recipient station knows how many data frames to expect based on the buffer status and can go to sleep after receiving the expected number of data frames. In another aspect, a source station receives a frame with information on transmission opportunity (TXOP) bursting receive capability of a recipient station operating in a power save mode. The source station performs channel access at the start of a TXOP and sends multiple data frames in the TXOP to the recipient station based on the TXOP bursting receive capability of the recipient station.

摘要： The disclosure is directed to an apparatus and method for encoder initialization and communications. The apparatus may include a database and an encoder module. The database may be configured to receive a plurality of parameters to be used for operation of the encoder module. The database may be further configured to store the plurality of parameters and to provide the plurality of parameters to the encoder module. The encoder module includes an encoder configured to be initialized based on the plurality of parameters from the database. When invoked, the encoder may rely on the database to initialize rather than performing measurements on the current signal that is to be encoded. In one aspect, the apparatus may be an access terminal that can seamlessly switch between different domains, different networks, different base stations, and different access points.

摘要： Techniques to enable efficient operation of co-located WLAN and Bluetooth devices are described. A station (e.g., a cellular phone or a laptop computer) determines the activity of a Bluetooth device and ascertains idle periods of the Bluetooth device. The station communicates with an access point in a WLAN during the idle periods of the Bluetooth device. The station may operate in a power save mode with the access point, send a poll frame to the access point during an idle period, and retrieve the buffered data from the access point during the idle period. The station may also operate in an unscheduled APSD mode with the access point, send a trigger frame to the access point during an idle period to start a service period, and exchange data with the access point during the service period.

摘要： Techniques for avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.

摘要： Techniques for selecting rates for data transmission on eigenmodes of a MIMO channel are described. An access point transmits an unsteered MIMO pilot via the downlink. A user terminal estimates the downlink channel quality based on the downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality and obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for the eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information. The access point processes data based on the selected rates and transmits steered data and a steered MIMO pilot on the eigenmodes with the eigenvectors.
