A repeater receiving an original frame from a connected Electronic Control Unit (ECU) by a normal port divides data stored in a data area of the received frame, and each of a plurality of divided data pieces is stored in the data area in each of a plurality of division frames to be sent out to a destination. Each of the plurality of division frames of the original frame is distributed to one of two ring ports according to a determination of the repeater, and each of the division frames is sent out therefrom to the destination. In such manner, the frame transmission time required for a transmission of the frame is reduced.

Technologies are described herein for time-synchronizing multiple remote network nodes concurrently with time beacons. A hub device in the network, at a preconfigured start time, begins to periodically broadcast time beacons containing current time values retrieved from an accurate time source over a beacon period, while other nodes of the network, at the same preconfigured start time, start listening for time beacons. When a node receives a time beacon broadcast by the hub device, the node sets a real-time clock of the node to the current time value in the received time beacon.

There is provided a main unit and a distributed antenna system including the same. The main unit for constituting a distributed antenna system that receives a base station signal from at least one base station, transmits the base station signal to at least one user terminal, and includes a plurality of main units, the main unit includes: a first receiver for receiving a first group of base station signals; a second receiver for receiving a second group of base station signals from another main unit; a signal combiner for combining the first and second groups of base station signals; and a delay compensator for compensating for time delay corresponding to a path between the main unit and the other main unit with respect to the first group of base station signals before combining the first and second groups of base station signals.

Embodiments of the present disclosure provide an apparatus including: a phase detector for detecting a write frequency of a deserializer and a read frequency of a serializer, such that the phase detector outputs a first code sequence in response to the write frequency being greater than the read frequency, or a second code sequence at the rotator input in response to the write frequency being less than the read frequency; and a phase rotator for receiving the first code sequence or the second code sequence from the phase rotator to transmit a pacing signal having the read frequency to the deserializer, wherein the pacing signal causes the read frequency to increase or decrease based on whether the read frequency is different from the write frequency.

An electronic device includes a die stack having a plurality of die. The die stack includes a die parity path spanning the plurality of die and configured to alternatingly identify each die as a first type or a second type. The die stack further includes an inter-die signal path spanning the plurality of die and configured to propagate an inter-die signal through the plurality of die, wherein the inter-die signal path is configured to invert a logic state of the inter-die signal between each die. Each die of the plurality of die includes signal formatting logic configured to selectively invert a logic state of the inter-die signal before providing it to other circuitry of the die responsive to whether the die is designated as the first type or the second type.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sounding reference signal (SRS) configuration that identifies an SRS resource set that includes a plurality of SRS resources. A quantity of SRS ports configured for a first SRS resource of the plurality of SRS resources may be different relative to a quantity of SRS ports with which a second SRS resource of the plurality of SRS resources is configured. The UE may transmit a first SRS on one or more first SRS ports in the first SRS resource, and may transmit a second SRS on one or more second SRS ports in the second SRS resource. Numerous other aspects are provided.

Methods and apparatus for efficiently directing communications are disclosed. On example entails receiving, from a mobile terminal, a communication directed to a cellular communication network, the communication being received in an alternative channel that differs from a channel of the cellular communication network. The communication is then converted for a relayed communication to the cellular communication network on behalf of the mobile terminal, the relayed communication being made through the cellular communication network.
