Abstract: A wireless mesh network system includes network nodes that operate in blink and canopy modes of operation. In operation, a network manager joins nodes operating in the canopy node to the network and allocates network bandwidth to the canopy nodes. The allocated bandwidth includes a first bandwidth allocated for transmitting and receiving data packets between canopy nodes that are joined to the network, and a second bandwidth allocation for receiving network joining messages from nodes that are not joined to the network. The second bandwidth allocation is also used for receiving data messages from nodes operating in the blink mode. Thus, in response to receiving a message that was transmitted from a blink node to a canopy node using the second bandwidth allocation, the network manager identifies the message as a data message and provides the data from the message to a host application.

Abstract: A method and apparatus are provided. an indication of a first uplink resource allocation of resource blocks for a transmission on a first carrier, and an indication of a second uplink resource allocation of resource blocks for a transmission on a second carrier are received. An indication of a downlink allocation for receiving a downlink signal is further received. A higher order intermodulation product, which is co-located with a lower order intermodulation product for the first and second allocations resulting from any respective higher order and lower order transceiver nonlinearities is identified. A determination is then made as to whether the co-located higher order intermodulation products have a region of overlap with the downlink allocation. When the co-located higher order intermodulation products have a region of overlap with the downlink allocation, adjustments in the operation are made to account for the overlap of the higher order intermodulation product and the downlink allocation.

Abstract: Different numerologies may be used to communicate orthogonal frequency division multiplexing (OFDM)-based signals over different frequency sub-bands of a given carrier. This may allow the OFDM-based signals to efficiently support diverse traffic types. In some embodiments, the numerology of OFDM-based signal depends on a bandwidth of the frequency sub-band over which the OFDM-based signals are transmitted. In some embodiments, the OFDM-based signals are filtered OFDM (f-OFDM) signals, and the pulse shaping digital filter used to generate the f-OFDM signals allows the receiver to mitigate interference between adjacent f-OFDM signals upon reception, thereby allowing f-OFDM signals to be communicated over consecutive carriers without relying on a guard band.

Abstract: A cellular network may provide location services so that clients such as public service access points (PSAPs) can obtain locations of mobile devices. A location request is received first by a Gateway Mobile Location Center (GMLC), which responds by querying a Mobility Management Entity (MME). The MME is configured to query a Serving Mobile Location Center (SMLC) for the location. In some cases, the SMLC fail to respond or may respond with an error indication. In response to certain types of errors, the MME is configured to attempt to obtain the requested location from an alternate SMLC, rather than reporting an error back to the GMLC. Status information is maintained by the MME to keep track of any SMLCs that have returned errors, and these SMLCs are avoided when processing further requests.
