A relaying module () includes a radio interface () and a processor (). The radio interface is configured to wirelessly receive uplink messages originating in a wireless device () that communicates messages with a Base Station (BS) () in a communication network (), and wirelessly transmit repeated uplink messages of at least some of the received uplink messages toward the BS. The processor is configured to hold one or more transmission constraints that define limitations of using network resources for wireless transmissions in the communication network, to receive one or more uplink messages from the wireless device, to select at least some of the received uplink messages for repeated transmission, to allocate to the selected uplink messages respective network resources so as to maximize performance of the communication network under the transmission constraints, and to transmit the selected messages as repeated messages toward the BS, in accordance with the allocated network resources.

Maximizing performance in extended-coverage wireless communication network under transmission constraints

A communication network () includes one or more replay modules (), one or more repeaters () and one or more processors (), () and (). The replay modules are configured to connect by Radio Frequency (RF) cable () to RF interfaces () of respective Base Stations (BSs) () that provide connectivity between wireless devices () and servers () over a packet network (). Each of the repeaters is configured to wirelessly communicate with one or more wireless devices, and to further communicate with one or more BSs via respective replay modules. The processors are configured to receive messages originating from one or more of the wireless devices and destined to the servers, to process the messages to determine a scheduling plan for transmitting the messages to one or more selected BSs, and to emulate to the selected BSs transmissions of the wireless devices, by transmitting the messages to the selected BSs via the respective replay modules, in accordance with the scheduling plan.

Low power network with extended coverage

A method includes, in a transceiver (), receiving from a repeater () a received signal, which includes a desired signal for reception and an undesired replica of a transmitted signal that was transmitted from the transceiver and retransmitted by the repeater. A local copy of the transmitted signal is generated in the transceiver. A filter response that, when applied to the transmitted signal before transmission, compensates for a difference in spectral response between the local copy and the undesired replica, is estimated in the transceiver. The undesired replica of the transmitted signal, which is received in the received signal, is matched with the local copy of the transmitted signal, by at least pre-filtering the transmitted signal before transmission with the estimated filter response. Interference caused by the undesired replica to the desired signal is canceled, by combining the local copy and the received signal.

Echo cancellation with transmitter-side pre-filtering

A method includes, in a transceiver (), receiving from a repeater () a received signal that includes a desired signal for reception and an undesired replica of a transmitted signal that was transmitted from the transceiver and retransmitted by the repeater. A local copy of the transmitted signal is generated in the transceiver. The local copy is matched with the undesired replica of the transmitted signal in the received signal, by adapting the received signal while retaining the local copy non-adaptive. An interference caused by the undesired replica to the desired signal is canceled, by subtracting the local copy from the adapted received signal.

Echo cancellation in communication transceivers

A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder.
