Abstract: Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include receiving, from a radio node in the RAN, a new feedback indicator (NFI) that indicates whether acknowledgement signaling previously scheduled for transmission by the UE was received by the radio node. The acknowledgement signaling is associated with one or more first downlink (DL) hybrid ARQ (HARQ) processes. Such methods include, when the NFI indicates the acknowledgement signaling was not received by the RAN node, selecting a first HARQ codebook to be used for encoding the acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes. Such methods include, using the selected first HARQ codebook, encoding the acknowledgement signaling and the further acknowledgement signaling to obtain first encoded information and transmitting the first encoded information to the radio node via an uplink (UL) channel.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may obtain information indicative of a configuration to provide code block group (CBG)-based feedback for one or more semi-persistent scheduling (SPS) communications scheduled for the first device. The first device may then monitor for the one or more SPS communications in one or more CBGs of a TB in accordance with one or more SPS communication configurations. Based on the monitoring of the semi-persistent scheduling communications, the first device may generate one or more feedback bits associated with the one or more SPS communications, and may communicate, with a second device, the one or more feedback bits associated with the one or more SPS communications in accordance with the configuration to provide CBG-based feedback.

Abstract: Methods and apparatuses for transmitting and receiving sidelink information. The method includes: determining a priority/priorities of second data information and/or feedback information by a second device, allocating power for the second data information and/or the feedback information according to the priority/priorities; and/or scrambling and/or indicating the second data information and/or the feedback information by the second device by using an identifier. Hence, supporting multiple unicast sessions or groupcast sessions by the same device may be achieved.

Abstract: Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

Abstract: This disclosure pertains to systems and methods to detect network errors in a parallel redundant protocol (PRP) network. A node-level redundancy error subsystem of an intelligent electronic device (IED) maintains records (e.g., counts) of information associated with missing duplicate frames expected from node devices on the PRP network via redundant first and second local area networks (LANs). Non-zero counts of missing duplicate frames may be identified as network errors.

Abstract: Methods and apparatuses are described herein to address issues at the MAC layer resulting from potential Listen-Before-Talk (LBT) failures and delayed transmission. For example, a wireless transmit/receive unit (WTRU) may monitor a plurality of TX resource pools within a sidelink bandwidth part (BWP) for LBT events. The WTRU may cause, based on determining that an LBT failure has occurred, a corrective action associated with a sidelink MAC procedure. The WTRU may determine, based on the LBT failure, that a total number or consecutive number of detected LBT failures for one of the monitored TX resource pools exceeds a threshold, indicating a consistent LBT failure. The WTRU may, based on the consistent LBT failure, send an indication of the consistent LBT failure for the TX resource pool to peer WTRUs. and an indication of the consistent LBT failure for the TX resource pool to a serving cell.
