A radio communication device switches a frequency channel to be used by using a predetermined hopping pattern during communication with a counterpart radio communication device, and includes a null determination unit that determines a position of a null symbol included in a received packet received from the counterpart radio communication device and an interference measuring unit that measures an interference amount by using the null symbol included in the received packet.

A data receiver is configured to receive a signal including a plurality of partial data packets, wherein the plurality of partial data packets each include part of a data packet, wherein the data receiver includes a multi-stage correlator that is configured to perform multi-stage correlation to detect the partial data packets in the received signal, wherein a second correlation stage of the multi-stage correlator operates based on correlation results of a first correlation stage of the multi-stage correlator.

A wireless wideband transceiver may be able to communicate with multiple frequency-hopped spread-spectrum (FHSS) devices concurrently over multiple frequencies over a short range by including a plurality of digital chains corresponding to the FHSS physical channels, individually and dynamically compensated for in-phase/quadrature imbalance in the transmit and/or receive portion. To further improve communications the transceiver may also mitigate cross interference between adjacent channel signals that are received and/or transmitted simultaneously, avoid false reception and/or transmission of co-channel signals, delay respective FHSS channels transmissions relative to other channels transmissions, speed up connection to FHSS devices and coordinate Time Division Duplexing (TDD) operation according to application dependent TX/RX binary pattern. A device that includes such a transceiver (FHSS-hotspot) may enable the concurrent usage of multiple commercially available FHSS peripheral devices without the need for additional personal host devices to be carried along with them, and in addition enable the concurrent usage of multiple commercially available FHSS personal data devices while reducing their radiation and/or latency and/or usage cost and/or power, to establish a localized multi-device multimedia session, and/or to interface with a communications network to communicate with remote parties, and/or to interface with broadcast devices to stream contents.

A wireless device includes a radio transceiver, and a digital transmitter configured to transmit, via the radio transceiver, a first data symbol, and to transmit, via the radio transceiver, a repetition of the first data symbol immediately after the first data symbol, where the first data symbol forms a cyclic prefix for the repetition of the first data symbol.

A method of capturing usage data of a usage area, which includes an automatic meter reading (AMR) device that broadcasts the usage data over a sequence of radio-frequency (RF) channels via a frequency-hopping spread spectrum (FHSS) signal. The method includes the steps of providing an RF receiver for the usage area, determining the sequence of RF channels, and receiving the usage data by tuning the RF receiver to an RF channel based on the sequence of RF channels. The sequence of RF channels includes an array of RF channels assigned to and ordered based on a channel position.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.
