A method and apparatus for discontinuous reception (DRX) of downlink signal for sidelink transmission is provided. A wireless device operating in a wireless communication system monitors a physical downlink control channel (PDCCH) carrying a sidelink grant during an active time including a time interval for which a scheduling request (SR) is transmitted on a physical uplink control channel (PUCCH) and is pending, based on the SR being triggered for a sidelink buffer status report (SL BSR) and/or a sidelink channel state information (SL CSI) reporting.

Artificial Intelligence (AI) can rapidly evaluate a faulted message in 5G or 6G, calculate a likelihood that each message element is faulted, and optionally suggest a most probable corrected version for each of the likely faulted message elements. To do so, the AI takes in numerous factors besides the message itself, such as the modulation quality of each message element, the proximity and quality of a nearest demodulation reference, a signal-to-noise ratio of the message element, a measure of current electromagnetic noise during the message element, an expected format or expected codewords based on prior messages or convention, and other factors. The AI model can then provide guidance as to mitigation, such as choosing whether to request a retransmission or attempting to vary the likely faulted message elements. The AI model can be adapted to fixed-site computers or to the more limited computers of a mobile user device.

Apparatus and methods of bandwidth part (BWP) operation for multiple downlink control information (DCI) based multiple transmit receive points (TRP) transmission are disclosed. The apparatus includes: a receiver that receives a plurality of Downlink Control Information (DCIs) in a slot, each of the DCIs having a Bandwidth Part (BWP) indicator field for indicating a BWP for a corresponding downlink (DL) reception or uplink (UL) transmission; and a processor that detects whether any one of the BWPs indicated in the DCIs is different from a current BWP which is used to receive the DCIs; and, upon detection that at least one of the BWPs indicated by the DCIs is different from the current BWP, configures the receiver and/or a transmitter to perform a BWP change.

A wireless device receives configuration parameters indicating PDCCH skipping durations. The wireless device may receive a DCI indicating PDCCH monitoring skipping for a first duration of the durations. The wireless device may transmit a random access preamble. The wireless device may ignore the PDCCH monitoring skipping and may monitor the PDCCH during a random access response window in response to transmitting the random access preamble.

A method for providing backhaul dynamic link distance for backhaul is disclosed. In one embodiment, the method includes propagating, by a network owner, a configured link distance parameter as part of beacon; using, by a mesh node joining the network, the configured link distance parameter for backhaul to set slot-time and Acknowledgement (ACK)/Clear To Send (CTS) timeout values before joining the network; wherein the configured link distance parameter for backhaul is part of a backhaul network profile.

The technique herein optimizes delivery performance from a content delivery network (CDN) edge node, preferably by using knowledge of radio link allocation behavior. According to the technique herein, an IP address of a cellular end user (or equivalent) is recognized by the CDN edge. Then, preferably by tracking idle times both in consecutive downloading bursts in the end user session and in an on/off style radio link allocation pattern, the CDN edge adjusts transport layer network protocol parameters. The approach (which leverages the cross-layer intelligence obtainable from existing CDN infrastructure) thus enables the transport layer protocol implemented at the edge to optimize the delivery performance over the cellular mobile network.

A timer control method includes a receiving device that performs re-establishment or data recovery on a Packet Data Convergence Protocol (PDCP) layer of the receiving device. The PDCP layer stops the running of a reordering timer of the PDCP layer when the reordering timer is in a running state, where the reordering timer enables the PDCP layer to wait to receive a lost data packet. Because the reordering timer is stopped from running rather than expires, the PDCP layer does not update a value of RX_DELIV.

Embodiments of the preset application provide a method and apparatus for configuring an active state of DRX, a User Equipment (UE), and a storage medium. The method includes: configuring at least one UE to be in the active state within a valid time, wherein a start time point of the valid time is a time point when the at least one UE sends or receives sidelink control information, or a time point within a period since the at least one UE sends or receives the sidelink control information.

A user equipment (UE) is described. The UE includes a processor configured to determine a coding method for multiplexing hybrid automatic repeat request-acknowledgement (HARQ-ACK) with different priorities on a physical uplink control channel (PUCCH). The coding method is determined based on higher layer signaling, an uplink control information (UCI) payload size or PUCCH resource configuration. The processor is also configured to multiplex the HARQ-ACK based on the determined coding method. The UE also includes transmitting circuitry configured to transmit the multiplexed HARQ-ACK on the PUCCH.

Message faults are likely to be common in the noisy, high-density wireless environments planned for 5G and 6G. Disclosed is a method for a receiver to recover the correct message from one or more corrupted message copies, by (a) measuring the modulation quality of each message element, and (b) determining which message elements of two corrupted copies are “inconsistent”, that is, the corresponding message elements are different. The modulation quality can be determined according to how close the message element's modulation is to the predetermined modulation levels of the modulation scheme. The receiver can assemble a merged message by selecting whichever message elements of the two copies have the best modulation quality, and determine whether the merged message is still corrupted. If so, the receiver can sequentially replace the inconsistent message elements with those of the other copy, singly or in a comprehensive nested search, testing each version until successful.
