A faulted message element in 5G or 6G can often be identified according to its modulation parameters, including a large deviation of the branch amplitudes from the predetermined amplitude levels of the modulation scheme, and/or the SNR of the branch amplitudes, and/or an amplitude variation of the raw signal or the branches during the message element, and/or an inconsistency between the modulation state as determined by the amplitude and phase of the raw waveform versus the amplitudes of the orthogonal branch signals, among other measures of modulation quality. An AI model may be necessary to correlate the various quality measures, and optionally to determine the correct demodulation of faulted message elements. Costly, time-consuming retransmissions may be avoided by determining the correct demodulation of each message element at the receiver, thereby improving throughput and reliability with fewer delays.

A transceiver is designed to share memory and processing power amongst a plurality of transmitter and/or receiver latency paths, in a communications transceiver that carries or supports multiple applications. For example, the transmitter and/or receiver latency paths of the transceiver can share an interleaver/deinterleaver memory. This allocation can be done based on the data rate, latency, BER, impulse noise protection requirements of the application, data or information being transported over each latency path, or in general any parameter associated with the communications system.

This application provides an acknowledgment packet transmission method and a communications device. The method includes: receiving, by a first device, data sent by a second device; sending, by the first device, the acknowledgment packet to the second device, where the acknowledgment packet includes an acknowledgment field, the acknowledgment field carries data lengths of K groups of data packets, and the data lengths vary with a data amount included in each group of data packets received/lost by the first device.

A wireless communication device is disclosed. The wireless communication device includes a processor, a transceiver coupled to the processor, and a memory coupled to the processor. The memory is configured to store a plurality of instructions and the plurality of instructions are executed by the processor to perform operations of storing, in the memory, a duplication of each of the plurality of packets transmitted by a streaming provider; and in response to a request of retransmission transmitted by a terminal device for a lost packet, determining whether the duplication of the lost packet is stored in the memory.

The present invention provides a method and system of periodic transmission of data between a first entity and a second entity within a mobile communication network. In order to increase transmission quality and take into account application characteristics of the network entities the first entity is able to obtain an adverse response from the second entity and provide an ancillary message to the second entity, where the ancillary message may have different contents depending on transmission circumstances, with the aim to increase the quality of transmission and to ensure the application requirements are met in different situations.

A communication protocol provides improved bidirectional communication performance between a wireless stereo headset (12) and a host device (19). The communication protocol provides communication paths between the host device (19) and each ear piece (12a, 12b) of the wireless stereo headset (12), as well as a communication path (17) between the two ear pieces (12a, 12b). In addition to receiving audio information from the host device (19), each ear piece (12a, 12b) may request audio information from the other ear piece (12b, 12a), thus obtaining path diversity in the downlink. One ear piece (12a, 12b) may acknowledge the host device (10) for a correctly received packet, which the other ear piece (12a, 12b) missed, avoiding retransmissions. The ear pieces (12a, 12b) may exchange picked-up voice content to send to the host device (19), providing for path diversity in the uplink.

This disclosure provides systems, methods and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a broadcast sidelink communication that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the broadcast sidelink communication to the second UE.

The apparatus may be a first device at a first RU (e.g., UE, base station, etc.). The first RU may be configured to receive, from a control unit, a configuration for relaying or repeating data received from a second RU to a receiving unit. The first RU may further be configured to determine whether first feedback associated with the data is received from the second RU. The first RU may also be configured to transmit second feedback to the receiving unit or the control unit, the second feedback including first information indicating at least one of the first feedback or whether the first feedback was received.

Embodiments are disclosed for group cast with retries (GCR) in a multi-link wireless communications system. In some embodiments, an access point (AP) multi-link device (MLD) can exchange information with a non-AP MLD to establish a GCR-multi-link operation (MLO) agreement corresponding to a group address, wherein the information includes, but is not limited to: a GCR primary link or a GCR primary link set of the AP MLD, an association identifier (AID) that corresponds to the group address. In some embodiments, the AP MLD can transmit a GCR frame subject to the GCR-MLO agreement, where the GCR frame includes a sequence number assigned from sequence number space (SNS)_GCR_MLO defined at a MLD level, and generate a Group Temporal Key (GTK)_GCR_ML at the MLD level, where the GTK_GCR_ML enables encryption and decryption of the GCR frame.
