Abstract: Embodiments of the present disclosure provide a solution for operating radio bearers. According to embodiments of the present disclosure, a terminal device monitors a plurality of data packets transmitted from a network device on a radio bearer. If a reception of at least one data packet in the plurality of data packets is failed, the terminal device is able to discard the at least one data packet without requesting retransmission. The network device determines whether a retransmission condition for the at least one data packet is unfulfilled. If the retransmission condition is unfulfilled, the retransmission of the at least one data packet is skipped.

Abstract: The automated test equipment is configured to establish communication, e.g. by uploading a program to the DUT using a first interface, such as a debug interface or a generic interface having access to the processing unit for external control. A typical use case of the first interface is debug access to the DUT, which typically requires limited data rates. In the case of the invention the first interface is an ATE access for test execution. The first interface configures the DUT to open a second interface running at much higher data rate, which is higher than the first interface, for additional communication. Additionally, the second interface may have extended capabilities compared to the first interface, such as presenting its own memory to the processing unit of the DUT as a normal system memory.

The quantum computing system configures the quantum computing circuit to implement a quantum error correction protocol using the QECC and at least one of the identified diagonal physical gates.

Abstract: This application provides a polar encoding method and apparatus. The method can include obtaining a basic sequence, where the basic sequence includes N0 subchannel numbers. The method can also include sequentially reading first subchannel numbers from the basic sequence, and sequentially reading 2m second subchannel numbers from the basic sequence starting from an Mth subchannel number based on the first subchannel number read each time; and adding q*N0 to each of the 2m second subchannel numbers to obtain 2m third subchannel numbers. Furthermore, the method can include constructing a polar code by using subchannels corresponding to the 2m third subchannel numbers as information bits. A polar code with another code length is constructed based on a sequence with a length of N0. A length of a polar code that needs to be stored is therefore reduced, which reduces complexity and is also easy to implement.

Abstract: Disclosed in some examples are methods, systems, devices, and machine-readable mediums which provide for an enhanced decoding system that utilizes a variable sequence decoding to demultiplex data streams at a receiver. For example, the receiver may utilize an erasures decoding when the number of unknown bits, such as dissimilar transmitted bits (e.g., ‘1 0’ or ‘0 1’), is below a threshold (which may be the Hamming distance D?1). Otherwise, if the number of dissimilar transmitted bits is above the threshold, a list decoding is utilized. If the list decoding does not produce a single result, but instead produces multiple possible results, selection logic may be employed. The selection logic may utilize an errors and erasures decoding of the possible results, a media decoding of the possible results, and/or the like.
