Abstract: PROBLEM TO BE SOLVED: To facilitate processing service data units (SDUs) in order during communication handover in wireless networks.SOLUTION: For mobile devices using re-transmission schemes, SDUs can be processed in order by indicating to a target base station the 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 determines one or more SDUs the mobile device is preparing to re-transmit and waits for the determined SDU to be transmitted before processing subsequently received SDUs. Also, a timer can be utilized to end a waiting period for the SDU.

Abstract: PROBLEM TO BE SOLVED: To facilitate in-band notification of stale service data units (SDUs) in a radio link control (RLC) layer for wireless communications.SOLUTION: When SDUs become stale during protocol data unit (PDU) retransmission, in-band notifications are packed in retransmit PDUs for receipt and interpretation by a receiver. The in-band notification is a special length indicator that specifies discard of an SDU that has been previously partially received, and a transmitter of the PDU saves payload by not retransmitting the stale SDU.

Abstract: PROBLEM TO BE SOLVED: To provide a technology for rate selection in a MIMO system. SOLUTION: An access point transmits an unsteered MIMO pilot via a downlink. A user terminal estimates downlink channel quality based on a 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, obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for 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.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for maintaining in-sequence delivery of packets through a handoff without incurring significant processing delays.SOLUTION: Provided are systems and methodologies that support Packet Data Convergence Protocol (PDCP) reordering of packets during a handoff operation. This invention can mitigate processing delays associated with PDCP reordering of packets at handoff by determining, communicating, and/or otherwise identifying during handoff one or more indicators that facilitate lossless communication of packets to a terminal with minimal delay. These indicators can include sequence number information for a source Node B, information regarding a step or jump size applied to a sequence number by a target Node B, a reset command, and/or other suitable indicators.

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for identification of a channel associated with a wireless data transmission.SOLUTION: A channel designated for transmission of a packet can be selected from among multiple usable channels, on the basis that a bit at a predefined location in the packet can be set to a logical value indicative of the selected channel. Furthermore, extraction of the logical value from the predefined location and identification of the corresponding channel can be performed by a recipient of the packet without requiring parsing of the message. A Dedicated Control Channel (DCCH) can be identified by setting a Logical Channel Identifier (LCID) bit in a DCCH packet to a predefined value. In another example, a Common Control Channel (CCCH) can be identified by embedding a Boolean constant within a message structure contained in a CCCH packet.

Abstract: PROBLEM TO BE SOLVED: To provide user equipment (UE) in a wireless communication system, and a method for allowing the UE to handle measurement gaps.SOLUTION: In some aspects, gap measurement may be ignored. In some aspects, the processing is stored and handled later in time, and the gap measurement is performed. Depending on the system, the measurement performed during the gaps may be UE implementation dependent, where the UE determines whether to perform the measurement during a given gap. In some instances, the UE may not perform measurement during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurement during the gap or ignore the gap measurement as if there were no gaps.

Abstract translation: 要解决的问题：在无线通信系统中提供用户设备（UE），以及允许UE处理测量间隙的方法。解决方案：在一些方面，可以忽略间隙测量。 在一些方面，处理在时间上较晚地被存储和处理，并且执行间隙测量。 根据系统，在间隙期间执行的测量可以是UE实现相关的，其中UE确定在给定间隙期间是否执行测量。 在某些情况下，UE可能在间隙期间不执行测量，从而优先考虑诸如RACH处理的其他处理。 根据所需的处理类型（DL-SCH，UL-SCH，TTI绑定，RACH或SR），UE可以存储请求并处理间隙期间的测量，或者忽略间隙测量，就好像没有间隙一样。

Abstract: PROBLEM TO BE SOLVED: To provide techniques for improving power saving by stations in wireless networks.SOLUTION: 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 (1412). 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 (1414). The recipient station knows how many data frames to expect based on the information on the TXOP bursting receive capability and can go to sleep state after receiving the expected number of data frames.
