摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first physical uplink shared channel (PUSCH) using one or more physical layer (PHY) parameters associated with a first block error rate (BLER) target performance. The UE may receive, from the base station prior to expiration of a round trip timer associated with the first PUSCH, downlink control information (DCI) scheduling a second PUSCH and configuring one or more PHY parameters associated with a second BLER target performance. The UE may transmit, to the base station, the second PUSCH using the PHY parameter(s) associated with the second BLER target performance, wherein the second PUSCH includes a retransmission of the first PUSCH or a new transmission based at least in part on a hybrid automatic repeat request process indicated in the DCI. Numerous other aspects are described.

摘要： A receiver can determine that a received message is corrupt according to an associated error-detection code in 5G/6G. The receiver can then calculate the modulation quality of each message element of the message by comparing a modulation value of the message element with a set of predetermined modulation levels, wherein a larger deviation from the closest predetermined modulation level corresponds to a lower modulation quality. Noise and interference usually generate random changes in the modulation as-received, and this generally results in a larger deviation relative to the predetermined modulation levels and hence a lower modulation quality. The receiver can count the number of faulted message elements with modulation quality below a threshold, and if the number of faults is less than some limit, the receiver can attempt to recover the message by altering the worst-quality message elements, testing each version for consistency.

摘要： The present disclosure provides a method and apparatus for generating equivalent nonlinear noise. The method includes randomly generating white noise obeying zero-mean Chi-square distribution; and filtering the input white noise by using an equivalent nonlinear noise spectrum as an equivalent nonlinear filter to obtain the equivalent nonlinear noise. According to the embodiments of the present application, equivalent nonlinear noise may be generated based on zero-mean Chi-square distribution random variables combined with equivalent nonlinear noise spectrum filtering, and more accurate equivalent nonlinear noise than the related art may be generated, thus accurately evaluating an influence of nonlinearity of devices on Bit Error Rate (BER).

摘要： Disclosed herein are systems and methods for network traffic shaping and/or adjustment of discontinuous reception (DRX) cycles. A wireless device determines a delay between a time at which a packet is transmitted from a server, to a time of arrival of the packet at the wireless device. The wireless device determines jitter of packets arriving at the wireless device from the server. The wireless device sends a message corresponding to the determined delay and the determined jitter, to the server to perform shaping of packet traffic from the server to the wireless device according to a latency budget of the packet traffic. The wireless device adjusts a length of a discontinuous reception (DRX) cycle of the wireless client device, to align with and to receive the packet traffic shaped by the server.

摘要： A detection method and apparatus, a terminal, and a storage medium are provided. The method includes that: a decoding parameter in a process that a decoder of a Narrowband Physical Downlink Control Channel (NPDCCH) decodes Downlink Control Information (DCI), a comparison parameter obtained by comparing an encoding result obtained by reversely encoding the decoded DCI by an encoder of the NPDCCH with the DCI before decoding, and a Signal-to-Noise Ratio (SNR) of the DCI are acquired; in a case where the decoding parameter, the comparison parameter and the SNR satisfy a first valid condition, a data transmission repetition number and a search space length of the NPDCCH are acquired; and in a case where the search space length matches the number of subframes corresponding to the data transmission repetition number, it is determined that the DCI is valid.

摘要： The present disclosure relates to a computer-implemented method of operating a wireless network access point of a wireless network. The method includes wirelessly exchanging management frames with a device to attach the device to the access point, thereby establishing: a wireless downlink data communication channel from the access point to the device, and a wireless uplink data communication channel from the device to the access point. The method further includes performing a wireless link test comprising: transmitting a test frame to the device on the downlink channel, the test frame having a length greater than each of the management frames, including a sequence of test data bits, and being configured to require a mirror response comprising the sequence of test data bits; monitoring for receipt of the mirror response on the uplink; and, if the mirror response is received, determining the test is passed.

摘要： A review and retry mechanism ensures a port channel can be configured to provide and maintain a minimum data speed. A timer-based review sequence reviews the constituent interfaces of a port channel to determine if a minimum speed requirement is met. If the minimum speed cannot be fulfilled, the port-channel member interfaces are un-programmed and removed from the port-channel, rendering the port-channel functionally inactive, thereby preventing network traffic loss. A timer-based retry sequence attempts to program the constituent interfaces. The minimum speed requirement of the interfaces is checked in the next review cycle. If the minimum speed requirement is met, then the review and retry mechanism halts and the port channel continues to remain active; otherwise, the interfaces are un-programmed and the process repeats.
