摘要： This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.
摘要翻译：本发明在用于E-UTRA切换的无线载体相关数据处理方法中采用固有的权衡。对于使用实时数据的用户设备，源节点向目标节点转发尚未确认的实时业务数据单元和断开连接。这使得切换延迟短于节点之间的数据流量。对于不需要实时数据的用户设备，源节点在超时期间继续接收用户设备确认，只转发在超时期间确认的业务数据单元。这减少了源节点和目标节点之间的X2接口流量，但是扩展了切换延迟。

摘要： A system and method for coordinating interference in cellular systems are disclosed herein. In one embodiment, a cellular base station interference coordinator includes an interference estimator. The interference estimator estimates a level of interference caused by transmissions controlled by a host base station for each of a plurality of radio resources, and provides interference estimates corresponding to the radio resources to a target base station. Each interference estimate is based on transmit power and channel strength to the target base station for each transmission controlled by the host base station for a radio resource.

摘要： Embodiments of the invention provide a method to efficiently enable Network MIMO for use in the downlink direction. An association is established between a primary NodeB in a first cell and a secondary NodeB in an adjacent second cell. A set of downlink transmission resources is reserved for use by both the primary NodeB and the secondary NodeB. A transport block is transmitted from the secondary NodeB simultaneously with the primary NodeB to a user equipment (UE) near the edge of the first cell in response to a schedule provided by the primary NodeB. A time instance of the reserved transmission resources is released by the secondary NodeB when no simultaneous transmission of a transport block is scheduled within a minimum time.

摘要： Network circuitry and a method of operating the same in establishing and deleting a service flow in a wireless network. A network station receives a request, from an initiating network station, to establish a service flow. The network station receiving the request issues a response to that request, following which it expects an acknowledgement from the initiator. Upon absence of such an acknowledgement, the receiving station transmits a message, to the initiator, to explicitly delete the service flow. This ensures that the initiator is not placed into an ambiguous state of transmitting payload traffic to a receiver that is ignoring or not receiving that traffic, in the case in which the initiator is also the transmitter of the payload traffic. This circuitry and method also ensures that the initiator is not in an ambiguous state, in the case in which it is the intended receiver of the payload traffic.

摘要： Apparatus, systems, and methods disclosed herein operate to provide wireless communication between personal mobile communication (PMC) devices. An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.

摘要： A method of performing wireless communications. The method receives at a receiving unit a sequence of data blocks from a transmitting unit. The method also identifies at the receiving unit a first number of invalid sequential data blocks in the sequence and a second number of valid sequential data blocks in the sequence. The method also communicates from the receiving unit a wireless message to the transmitting unit. The wireless message comprises a first field that specifies the first number and a second field that specifies the second number—the encoding of the first field is operable to specify a different maximum than an encoding of the second field.
