A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node detects that a number of RLC Data PDUs transmitted by the peer AM RLC entity are missing, and constructing a STATUS PDU to include NACK_SNs for a first part of the missing RLC Data PDUs and omitting NACK_SNs for the rest of the missing RLC Data PDUs. The receiving node further sets the ACK_SN field of the status PDU such that the status PDU includes only acknowledgments for PDUs having a sequence number equal to or less than the minimum sequence number omitted from the status PDU, and sends sending the STATUS PDU from the AM RLC entity to the peer AM RLC entity over the radio link.

A method, wireless device and network node are disclosed. According to one aspect, a wireless device includes a radio interface configured to obtain a timer value, T, for measuring time elapsed from a start of a semi-persistent scheduled, SPS, uplink, UL, data transmission. The wireless device includes processing circuitry configured to perform an SPS UL data transmission associated with a hybrid automatic repeat request, HARQ, process identification, ID, wherein the HARQ process ID is one of a plurality of HARQ process IDs. The processing circuitry is configured to perform a new data transmission or autonomous retransmission with said HARQ process ID at the next available time for said HARQ process ID after elapsed time T.

Methods, systems, and devices channel quality indicator (CQI) reporting based on demodulation reference signal (DMRS) from a base station are described. In some cases, a base station may configure a user equipment (UE) with such DMRS based CQI reporting (e.g., by transmitting a CQI reporting configuration to the UE). The CQI reporting configuration may specify the UE is to report CQI based on DMRS and, in some cases, may configure the UE to report the CQI with hybrid automatic repeat request (HARQ) feedback. A UE may receive a control message that indicates a resource for reception of a downlink transmission and an uplink control resource for transmission of CQI information. The UE may identify a DMRS of the downlink transmission, calculate a CQI based on the DMRS, and transmit the calculated CQI to the base station via the uplink control resource indicated by the received control message.

Methods, systems, and devices for wireless communications are described. Techniques for multiple transmission reception points (TRPs) in a cluster may coordinate scheduling and communications with a user equipment (UE). Different TRPs may allocate uplink resources for one or more UEs within a coordinated cluster to transmit feedback information. A first TRP may provide a first set of resources that one or more associated UEs may use to transmit acknowledgment (ACK) feedback to indicate successful receipt of a downlink transmission of the first TRP, and one or more other TRPs of the coordinated cluster may provide a second set of resources that the one or more UEs may use to transmit negative acknowledgment (NACK) feedback to indicate that a downlink transmission of the first TRP was lost. The second set of resources may include non-orthogonal multiple access (NOMA) resources.

Systems and methods for improving the performance and stability of bonding radios are provided. One method includes receiving a packet from a client device. Next, the method includes determining whether the received packet is an expected next packet and transmitting the received packet to a next destination if the received packet is the expected next packet. In an event the received packet is not the expected next packet, transmitting the received packet to a queue, setting a timer to wait for the expected next packet, and transmitting a message to the sender of the received packet requesting that the expected next packet be sent.

Methods, systems, and devices for wireless communication are described. A transmitting device may determine reconstruction information for a time-domain signal and may transmit the reconstruction information with the time-domain signal to a receiving device. The transmitting device may generate the reconstruction information based on estimates of how the receiving device may process the time-domain signal. For example, the transmitting device may apply a channel estimate to samples of the time-domain signal, and further perform clipping and quantization of the samples based on an estimated dynamic analog-to-digital converter (ADC) resolution of the receiving device. The transmitting device may generate the reconstruction information (e.g., using machine learning or other techniques) based on samples having the channel estimate applied and the clipped and quantized samples. The receiving device may process the received time-domain signal and use the reconstruction information to reconstruct the processed time-domain signal.

A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel (e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration.

The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: based on the UE transmitting the UL data on a first UL resource of a configured grant (CG) con-figuration based on a Hybrid-ARQ (HARQ) process, starting a CG retransmission timer for the HARQ process and a CG timer for the HARQ process; based on a second UL resource of the CG configuration not being configured between an expiration time point of the CG retransmission timer and an expected expiration time point of the CG timer, stopping the CG timer upon expiration of the CG retransmission timer; and performing retransmission of the UL data based on the HARQ process after the expected expiration time point of the CG timer.

Disclosed is a base station which transmits and retransmits to a terminal first and second downlink data in first and second component carriers, respectively, wherein a first configuration pattern of UL (uplink) and DL (downlink) subframes is set for the first component carrier and a second configuration pattern of UL and DL subframes is set for the second component carrier. The base station receives from the terminal in the first component carrier an ACK/NACK for the first and second downlink data received by the terminal, which stores retransmission data of the first and second downlink data in a soft buffer, wherein the soft buffer for the second downlink data is sized according to a maximum number of downlink HARQ retransmission processes executable in a reference configuration pattern of UL and DL subframes, and the reference configuration pattern is determined according to the first and second configuration patterns.

Provided are a data transmission method and apparatus. The method includes: receiving downlink data during a physical uplink shared channel (PUSCH) transmission; when the received downlink data is first feedback, terminating the PUSCH transmission; and when the received downlink data is second feedback, terminating the PUSCH transmission and executing a first operation.
