摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：要解决的问题：提供一种用于识别与无线数据传输相关联的信道的方法和装置。解决方案：可以从多个可用信道中选择指定用于传输分组的信道，其基础是在可以将分组中的预定位置设置为指示所选频道的逻辑值。此外，可以由分组的接收者执行从预定位置的逻辑值的提取和相应信道的标识，而不需要解析消息。可以通过将DCCH分组中的逻辑信道标识符（LCID）位设置为预定义值来识别专用控制信道（DCCH）。在另一示例中，可以通过在包含在CCCH分组中的消息结构内嵌入布尔常数来识别公共控制信道（CCCH）。

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To resolve confusion resulting from assigning the same identifier to multiple nodes.SOLUTION: A network may provide a time gap during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. An access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. A source node may prepare several target nodes for potential handover in the event confusion is detected or likely. The source node may send information relating to the preparation of the potential target nodes to the access terminal, and thereby the access terminal initiates handover at that target node.

摘要： PROBLEM TO BE SOLVED: To provide a method of selecting a sleep interval in a mobile communication device.SOLUTION: A mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network negotiates, while communicating over the packet-switched network, a sleep interval that is longer than the ordinary sleep interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conserves power. A buffering system is included so that data directed towards the device while the device is asleep is delivered later when the device awakens.

Each station may decide to power down until its start time. The service periods for the stations may overlap one another. The service period for each station may cover an initial transmission as well as additional transmission and/or retransmission.

摘要： PROBLEM TO BE SOLVED: To provide techniques for performing open-loop rate control in a TDD communication system. SOLUTION: In the open-loop rate control, the channel quality of a first link (B, A) is estimated based on a transmission received via the first link (B, A). The channel quality of a second link (A, B) is estimated based on the estimated channel quality of the first link (B, A) and an asymmetric parameter. A rate for a data transmission via the second link (A, B) is selected based on the estimated channel quality of the second link (A, B). The estimated channel quality for each link may be given by a set of SNR estimates for a set of transmission channels on that link. The asymmetric parameter may be determined based on (1) the capabilities (e.g., transmission power, receiver noise figure, and number of antennas) of the transmitting and receiving stations or (2) received SNRs for the first link (B, A) and second link (A, B).

摘要： PROBLEM TO BE SOLVED: To provide techniques for sending a message for random access by user equipment (UE).SOLUTION: The UE sends the message on a control channel for random access and sends a reserved channel identifier to indicate the message being sent on the control channel. In another aspect, the UE sends the message in a protocol data unit (PDU) and sends additional information in the PDU if the UE can accommodate to the additional information. In yet another aspect, the UE generates a short MAC-I (message authentication code for integrity protection) for the message. The short MAC-I may have a smaller size and may be used to authenticate the UE. In yet another aspect, the UE sends a UE ID for one of multiple types of random access and conveys the UE ID type via a format field in the message.
