摘要： A deterministic access system and method is provided that may be used for gaining access to a shared communication medium in a mesh or decentralized network. The deterministic access method enables QoS prioritization for periodic data flows such as those used in streaming media or VOIP communications without the direction of a central controller. The method provides a way for network nodes to schedule communications that take into account the hidden node problem, provide priority access to the communication medium for high QoS data flows, and provide shared access to the medium for lower priority data packets during unscheduled times. The method also enables both backward and forward compatibility with network communication methods as well as interoperability between mesh networks and conventional networks.

摘要： A mesh point operable in a decentralized wireless network is provided. The mesh point includes a transceiver and a processor. The transceiver is operable to communicate with other mesh points. The processor is programmed to execute a routing protocol such that, when a first policy of the routing protocol is selected and a transmission failure occurs between the mesh point and a current parent node of the mesh point, the processor is operable to execute instructions to promote finding another route to a root. The other route to the root is found by referencing a topology, if the topology is available, to identify the route to the root. If the route is not found, the transceiver transmits a one-hop broadcast route request. If the route is still not found, the mesh point enters a route discovery state.

摘要： A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.

摘要： A novel and useful synchronization mechanism that functions to provide a uniform time base for mesh points in a WLAN mesh based network. The invention enables timing synchronization to a common reference clock base by advertising the common TSF within beacon transmissions. All MPs in a mesh share a common DTIM interval. The synchronization mechanism enables the mesh points to avoid collisions in the generation and transmission of beacons. The TBTT offsets of the current MP and its neighbors are advertised in beacons so that neighboring MPs that hear the beacons can select non-overlapping TBTT offsets. Each MP receives one or more beacons from its neighbors and compares the timing of its neighbors to that of itself and adopts the highest TSF (i.e. the fastest) in the mesh. Eventually, all MPs in the mesh will adjust their timing to that of the MP with the fastest clock. The reception of beacons by MPs from its neighbors is also advertised. This allows for MPs to verify that the beacons they send are actually heard and are not in collision with beacon transmissions of other MPs.
摘要翻译：一种新颖有用的同步机制，用于为基于WLAN网络的网络中的网点提供统一的时基。本发明通过在信标传输中通告公用TSF来实现与公共参考时基的定时同步。网格中的所有MP共享一个常见的DTIM间隔。同步机制使网格点能够避免信标的生成和传输中的冲突。当前MP及其邻居的TBTT偏移在信标中公布，使得听到信标的相邻MP可以选择不重叠的TBTT偏移。每个MP从其邻居接收一个或多个信标，并将其邻居的定时与其本身的定时进行比较，并采用网格中最高的TSF（即最快）。最终，网格中的所有MP将以最快的时钟调整MP的时间。接收来自其邻居的议员的信标也被广告。这允许MP验证其发送的信标实际上被听到并且不与其他MP的信标传输相冲突。

摘要： A pre-synchronization method in which the source cell chooses a signature for the user equipment (mobile) to use in the target cell for RACH access, and instructs the user equipment to perform RACH access and return to the current cell before a handover command (break command) is issued. This causes parallel execution of the UL synchronization process with the context transfer process among the two base stations.
