Techniques and apparatus for transmitting control information to maintain hybrid automatic repeat request (HARQ) processes for multiple carriers in different frequency ranges, such as frequency range 1 (FR1) and frequency range 2 (FR2), in carrier aggregation scenarios are described. A first numerology of a first component carrier (CC) in FR1 and a second numerology of a second CC in FR2 are determined. A HARQ configuration that includes an indication of a set of physical uplink control channel (PUCCH) resources is determined. A number of symbols of the set of PUCCH resources is based on the first numerology and the second numerology. The HARQ configuration is transmitted to a user equipment (UE). HARQ feedback is transmitted on the first CC for data received on the second CC, using the set of PUCCH resources of the HARQ configuration.

A method of operating a network subscriber comprises receiving an input-data stream containing an input-transmission frame according to a field-bus protocol, where the input-data stream is received in chronologically successive data units having a defined processing width, decoding fields of the input-transmission frame by a plurality of field-processing units arranged in series, each field-processing unit decoding a predetermined field of the input-transmission frame, and generating an output-data stream comprising an output transmission frame according to the field-bus protocol from the input-data stream.

A network device sends at least one piece of DCI on a PDCCH monitoring occasion of a first PO, where all or a part of the at least one piece of DCI includes first indication information, each piece of first indication information indicates that at least one CSI-RS is available, the CSI-RS corresponds to an SSB, and the SSB corresponds to a PDCCH monitoring occasion for sending the DCI including the first indication information. The network device sends the CSI-RS indicated by the first indication information as available.

The present disclosure relates to reference signal resource configuration methods and apparatus. In one example reference signal resource configuration method, a terminal receives sounding reference signal (SRS) resource configuration information from a base station. In response to determining that at least two SRS resources indicated by the SRS resource configuration information are located on a same orthogonal frequency division multiplexing (OFDM) symbol, the terminal maps one of the at least two SRS resources to the OFDM symbol.

A transceiver transmits data via a first cable among a plurality of cables in a wired communication network, and selectively operates in one of (i) an active mode for transmitting data to a link partner via the first cable and (ii) a low power mode during which the transceiver quiets transmissions to conserve power. A crosstalk detector determines that transmission of data in the first cable is causing crosstalk in one or more second cables. A controller, in response to the crosstalk detector determining that transmission of the data in the first cable is causing crosstalk in one or more second cables, controls the transceiver to operate in the low power mode during a plurality of first time periods to reduce crosstalk in the one or more second cables during the plurality of first time periods.

A method includes: obtaining, by a first communications device, a first carrier, where the first carrier is used to transmit a first message and a second message; obtaining, by the first communications device, a first transmission resource and a second transmission resource of the first carrier, where the first transmission resource is used to send the first message, the second transmission resource is used to send the second message, and the first transmission resource and the second transmission resource are different transmission resources; sending, by the first communications device, the first message on the first transmission resource by using a first wireless access technology; and sending, by the first communications device, the second message on the second transmission resource by using a second wireless access technology, where the first wireless access technology and the second wireless access technology are different inter-device direct communications technologies.

A first relay node receives a first timeslot assignment message sent by an upper-level node, where the first timeslot assignment message includes forwarding information and first timeslot information, and the forwarding information includes a forwarding indication indicating that at least one relay node needs to forward the first timeslot assignment message. The first relay node updates the first timeslot information to obtain second timeslot information, where the updating includes deleting an expired timeslot indication from the first timeslot information. The first relay node sends a second timeslot assignment message including the forwarding information and the second timeslot information.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for flexible intra-symbol multiplexing of DMRS of different antenna ports for single carrier waveforms. A base station may transmit one or more DMRSs within a symbol and provide an intra-symbol guard interval prior to each of the one or more DMRSs. The intra-symbol guard interval may have a duration that is based on a duration of a CP. A UE may receive the one or more demodulation reference signals DMRSs within the symbol based on the intra-symbol guard interval prior to each of the one or more DMRSs, and perform a channel estimation based on at least one of the one or more DMRSs.
