A communication protocol system is provided for reliable transport of packets. A content addressable memory hardware architecture including an acknowledgment coalescing module in communication with a content addressable memory (CAM). The acknowledgment coalescing module coalesces multiple acknowledgement packets as a single acknowledgement packet to reduce the overall numbers of the packet transmission in the communication protocol system. In addition, the acknowledgment coalescing module may also provide a piggyback mechanism to carry acknowledge information in a regular data packet. Thus, the need to generate a new acknowledgement packet may be eliminated. Accordingly, the network congestion and latency may be reduced, and the communication and transmission efficiency are enhanced.

A data link quality-based offloading method in dual connectivity includes determining a quality of a bearer link on a user equipment UE side by determining and setting, determining a quality of a radio link by parameters or conditions such as timing advance (TA) timeout, a bit error rate, a signal strength or a signal amplitude, a threshold of continuous scheduling request (SR) sending, a radio link control (RLC) sliding window, a T310 timer, and a triggering of a beam failure recovery process, selecting, based on a determining result, a manner such as a packet replication or selecting a link, and transmitting data through two links.

The subject matter described herein is directed towards a technology that increases the reliability of transmitting information, by propagating received information in a location-controlled and route managed multiple-stage chain communication in a wireless communication system. A transmitting device transmits a broadcast or group-cast communication message in conjunction with transmitter and receiver location data (e.g., absolute or quantized coordinates). An intermediate device that receives the communication message determines a communication path based on the received location data, and determines whether the intermediate device is within the communication path based on its own location. Only intermediate devices that are within the communications path, and that otherwise satisfy retransmission policy, perform the retransmission. In one aspect, the communication path that is determined can be shaped based on one or more other factors, such as whether the communication message is highly reliable data traffic.

One innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a first multi-link device (MLD), that includes a first station (STA) and a second STA, to generate and provide block acknowledgment (BA) status reports for Medium Access Control (MAC) Protocol Data Units (MPDUs) transmitted by the first STA of the first MLD and the second STA of the first MLD. Another innovative aspect of the subject matter described in this disclosure may be implemented in a method for wireless communication. The method may be performed, for example, by a logical entity of a first MLD to receive and process a BA status report.

A transmission configuration and/or configuration errors and recovery may be determined or implemented by temporal interpretation of one or more signals. A transmitter may interpret one or more signals a first way during one or more time windows and a second way during one or more other time windows. Video resolution may be indicated in a V-by-One® interface by temporal interpretation of HPD and/or CDR lock. Transmission format may be indicated before or after transmission begins. Transmitter configuration error detection and recovery may be implemented by temporal interpretation. A transmitter may transmit data in an assumed/default format. A receiver may indicate the assumed transmission format is incompatible with the receiver configuration. A receiver may indicate a compatible transmission format, for example, based on timing or pulsing transitions in a temporally repurposed signal. A transmitter may respond to the repurposed signal indication by transmitting a different (e.g., compatible) format.

Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a pseudorandom number sequence, or “PN sequence”) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

Hybrid automatic repeat request (HARQ) configurability on new radio (NR) unlicensed (NR-U) operations is disclosed. Time varying code block group (CBG) granularity may be defined by signaling a set of available CBG granularities to a user equipment (UE) for HARQ feedback. The UE monitors for control signaling that may be used to select the CBG granularity for the current slot. The UE may then perform HARQ feedback according to a format corresponding to the selected CBG granularity. Additional aspects disclose updating a contention window size (CWS) in NR-U operations considering the varying CBG granularity. A base station may compute an effective HARQ feedback value that accounts for the varied CBG granularity corresponding to transmissions at a configurable reference slot of set of slots. The base station will update the CWS depending on the relationship of the failure rate of the effective HARQ feedback and a transmission failure rate threshold.

Provided is a terminal for performing transmission and reception of data in a wireless communication system, wherein the terminal receives, from a base station, first configuration information for code block group (CBG)-based uplink transmission, and second configuration information including a downlink feedback information (DFI) bitmap configuration method, transmits a CBG-based uplink signal to the base station, based on the first configuration information, receives, from the base station, DFI including feedback information about the CBG-based uplink signal, based on the second configuration information, and determines a contention window value of the terminal, based on the feedback information included in the received DFI, wherein the DFI bitmap configuration method indicates whether the feedback information is for feedback in units of transport blocks (TBs) or for feedback for one or more CBGs.

A method of monitoring a parameter of an electrical network includes using sensors to measure a value of a parameter of the electrical network during each sampling period within a selected time section. During each iteration of a plurality of iterations of a sliding window algorithm, wherein within each of the iterations a starting time of a sliding window of the sliding window algorithm within the selected time section is incremented by a selected increment, an average of the measured parameter values over the duration of the sliding window for each of the starting times is calculated. The duration of the sliding window in each iteration is different from the duration of sliding windows in other iterations. A representative value of the calculated averages of the parameter is calculated for each iteration. An alert is issued if indicated by the representative value.

A data processing method, where a first device communicates with a second device using a relay node, where the relay node does not have a Packet Data Convergence Protocol (PDCP) entity, and the method includes transmitting, by the first device, a first data unit group, where the first data unit group is in a first sequence range, receiving, by the first device, first information using the relay node, where the first information indicates a data unit that the second device has received or has not received in the first data unit group, determining, by the first device, a second sequence range based on the first information.
