摘要： Methods and systems for multi-protocol transmissions in shared spectrum are disclosed. According to principles described herein, a wireless transmitter is configured to generate subcarriers or symbol information from one OFDM technology using subcarriers of another OFDM technology. With this approach, a wireless transmitter configured to transmit OFDM symbols using subcarriers and a subcarrier frequency spacing associated with one OFDM protocol can also be configured to transmit OFDM symbols associated with another OFDM protocol which normally uses different subcarriers and a different subcarrier frequency spacing. In one application, an LTE transmitter uses LTE subcarriers to generate 802.11 (e.g. Wi-Fi) subcarrier or symbol information that can be understood by Wi-Fi receivers, for example to reserve the channel for a certain duration, to indicate a transmission time associated with an on-going and/or upcoming symbol transmission or to create a carrier sense indication, for example, to cause Wi-Fi receivers and other radio technologies to consider the channel as busy.

摘要： Methods and systems for multi-protocol beacon operation in shared spectrum (unlicensed band) are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. In one application, an LTE transmitter (LTE-U) uses LTE subcarriers to generate an interpolated 802.11 (e.g. Wi-Fi) beacon transmission that can be understood by Wi-Fi receivers, for example to reserve the channel for a subsequent LTE transmission. For instance a W-LAN preamble is generated where STF and LTF fields consist in respectively 12 and 52 subcarriers mapped at their respective frequency locations among the 2048 LTE subcarriers with the remaining subcarriers set to 0. In some implementations, the use of beacons can be useful in implementations where it is desirable to gain prioritized access to reserve the channel. Examples of suitable LTE transmissions that would benefit from prioritized channel access include delay or time-sensitive LTE transmissions or transmissions that must occur within a certain time window and/or with a certain periodicity such as LTE control data or signals (e.g. PDCCH), and/or synchronization or reference signals such as the Discovery Reference Signal (DRS) for LAA-LTE). An LTE transmitter can exploit the 802.11 channel access to gain prioritized channel access for transmitting 802.11 Wi-Fi beacons generated using its LTE subcarriers to ensure LTE transmissions take priority over other types of LTE and/or Wi-Fi traffic.

摘要： Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to generate and/or transmit LTE information using LTE subcarriers located in unused portion(s) of the Wi-Fi system bandwidth independently of or in addition to transmitting Wi-Fi or LTE information using LTE subcarriers located in portions of the Wi-Fi system bandwidth normally occupied by Wi-Fi subcarriers.

摘要： Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, multi-protocol transmissions as described herein may be performed sequentially (e.g. in a time division multiplexing fashion) or concurrently (e.g. during the same or an overlapping time interval). For concurrent transmissions, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to use different subsets of the LTE subcarriers for concurrent LTE and 802.11 transmissions that can respectively be decoded by LTE and 802.11 receivers.

摘要： A front-haul controller for a network coupling a BBU and an RRH that exchanges RF analog signals with a supported UE. The network comprises a plurality of nodes coupled by variable bit-rate network communications links. The BBU exchanges packets of frequency-domain samples with the RRH along the network. The front-haul controller monitors information about wireless spectrum occupancy at the RRH and at least one spectrum occupancy threshold and varies a bit-rate of the network link in accordance therewith. The front-haul controller can proactively adjust the bit-rate and/or the threshold during periods associated with at least one event that may impact the spectrum occupancy. The network link can be a FlexE, SONET, DWDM, LAG and/or ECMP link.

摘要： There is provided methods and apparatuses for managing front-haul network resources based on one or more front-haul network characteristics. One or more front-haul network characteristics are collected and/or determined by one or more front-haul network entities and are delivered to one or more network entities that manage front-haul network resources (e.g. scheduler, admission controller). The network entities, based on the received one or more front-haul network characteristics, manage network resources in their control. For example, management of the network resources can include scheduling use of the network resources by UEs, managing admission of UEs onto the communication network or other form of network resource management. By taking into account one or more front-haul network characteristics, the management of the network resources can be adapted to varying front-haul network requirements.

摘要： A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a route through the limited portion of the network to the target node is determined, other nodes are configured (e.g. via source routing) to cause the packet to traverse the determined route, and the packet is forwarded toward the target node.

摘要： A remote radio head (RRH) of a distributed radio access network (RAN) is equipped with a co-located user equipment (UE). The UE can be a chipset integrated into the RRH, which is connected to other parts of the RAN via a fronthaul network. The UE can be used to relay information, such as management information to and/or from the RRH. Timing information obtained by the UE can be provided to the RRH and used as an indication of fronthaul latency. The RRH can then adjust its operation in response to the indication of fronthaul latency.
