Abstract: Wireless communication techniques that include PTRS resource density recommendation and selection techniques are discussed. A UE may transmit to a base station a set of phase tracking reference signal (PTRS) resource density recommendations that are determined based, at least in part, on a block error rate (BLER). The base station may transmit to the UE an indication of PTRS resource densities to use for wireless communication of the PTRS based, at least in part, on the BLER associated with the received set of PTRS resource density recommendations. The base station and/or the UE may at least one of receive or transmit a PTRS based, at least in part, on the indicated PTRS resource densities. Other aspects and features are also claimed and described.

Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

Abstract: A data transmission method is provided. The data transmission method may be applied to a multi-link operation between a first multi-link device (MLD) and a second MLD. The data transmission method may include the following steps. A processor of the first MLD may perform a spatial reuse transmission on at least one link between the first MLD and the second MLD. Then, the processor may dispatch data frames with the same traffic identifier (TID) for all links between the first MLD and the second MLD based on the physical layer (PHY) rates and packet error rates of all links between the first MLD and the second MLD. Then, the processor may transmit the data frames to the second MLD based on the dispatch result.

Abstract: Technologies for optimizing post-FEC bit error rate performance of a Forward Error Correction (FEC) system are described. A controller is coupled to an FEC circuit and a receiver circuit. The controller receives FEC symbol error data from the receiver circuit and determines, using the FEC symbol error data, a post-FEC correlated performance metric indicative of an estimated post-FEC BER of the FEC circuit. The controller adjusts, based on the post-FEC correlated performance metric, at least one of a FEC parameter of the FEC circuit or a link parameter of the receiver circuit to decrease the estimated post-FEC BER. This improves the post-FEC BER performance of the FEC circuit.

Abstract: A method of wireless communication performed by a user equipment (UE) includes measuring a signal strength of a beam failure detection (BFD) reference signal (RS), the BFD RS being included in a BFD RS set that corresponds to a transmission reception point (TRP) of a plurality of TRPs; the method further includes identifying a BFD threshold associated with the TRP, detecting a beam failure instance associated with the TRP based at least in part on a determination that the signal strength of the BFD RS satisfies the BFD threshold and, providing an indication of the beam failure instance associated with the TRP. Numerous other aspects are described.

Abstract: The present disclosure provides a method and device for performing low-latency and high-speed transmission in a wireless communication system. The present disclosure also provides a method and device for performing efficient HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) feedback and retransmission for recovering a transmission error occurring in a wireless communication system. The present disclosure also provides a method and device for reducing transmission latency by reducing HARQ retransmission probability using an erasure code, and for reducing radio resources and the number of HARQ-ACK feedback bits and DCI bits required for retransmission when retransmission is unavoidably necessary.

Abstract: Described herein are embodiments related to first-pass continuous read level calibration (cRLC) operations on memory cells of memory systems. A processing device determines that a first programming pass of a programming operation has been performed on a memory cell of a memory component. The processing device then adjusts a read level threshold of the memory cell to be centered between a first programming distribution and a second programming distribution before the second programming pass of the programming operation is performed on the memory cell.
