Resolving decodability for subsequent transmissions whose throughput exceeds a threshold
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.
Communication method and apparatus in a point-to-multipoint communication network
A communication method and device are provided for communication in a point-to-multi-point communication network. A communication method includes receiving, by a node of a plurality of multi-point nodes, a transmission frame comprising a header including a repetition information and a data section comprising multiple modulation symbols, with at least two repeated modulation symbols that are repeated to represent a first modulation symbol; extracting, by the node, the repetition information of the header; recovering, by node, the amplitude of each modulation symbol of the at least two repeated modulation symbols; and combining, by the node, the amplitudes of the at least two repeated modulation symbols, based on the repetition information, to reconstruct the first modulation symbol represented by the at least two repeated modulation symbols.
Packet processing method and apparatus, and chip
A packet processing method includes generating, by a processor of a network device, a first encoding task based on M original packets in a to-be-processed first data stream, where M is a positive integer, and where the first encoding task instructs to encode the M original packets; and performing, by a target hardware engine of the network device and based on the first encoding task, forward error correction (FEC) encoding on the M original packets to obtain R redundant packets, where R is a positive integer.
Blind decoding limits
Certain aspects of the present disclosure provide techniques for allocating a resource budget for blinding decoding among various types of DCI. A method that may be performed by a user equipment (UE) includes allocating a resource budget per a span of symbols among a first type of downlink control information (DCI) and a second type of DCI, wherein the resource budget includes a number of physical downlink control channel (PDCCH) blind decodes (BDs) and a number of control channel elements (CCEs) supported by the UE; and monitoring, from a network entity, PDCCH candidates in accordance with the allocated resource budget.
Method to locate faulted message elements using AI in 5G and 6G
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.
Forward error correction decoder failure detection
Various embodiments described herein provide for a mechanism for detecting failure in the operation of FEC of a physical layer device, such as a physical layer device of a networking application that seeks to meet a functional safety standard (e.g., ISO 26262). In particular, some embodiments described herein provide one of several methods for detecting a failure in the operation of a FEC decoder of a physical layer device.
Resource sharing in a telecommunications environment
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.
Radio communication system, radio station, radio terminal, communication control method, and non-transitory computer readable medium
A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) or the second radio station (2) transmits constraint information to the radio terminal (3). The constraint information contains an information element necessary to specify a reception constraint and/or transmission constraint related to the first cell (10) and/or the second cell (20) when the carrier aggregation is performed. The reception/transmission constraint is a constraint related to downlink signal reception/uplink signal transmission by the radio terminal over one or more subframe periods of the primary cell (10) and the secondary cell (20). It is thus, for example, possible to contribute to reduction in wasteful power consumption in the radio terminal in the carrier aggregation of a plurality of cells served by different radio stations.
