A system for negotiating Ethernet link settings between interconnected nodes in a network having an Ethernet protocol stack that includes a PCS sub-layer with an auto-negotiation function. The system comprises connecting an intermediate device coupled between two network nodes via optical or copper interfaces, with the link settings between each node and the connected intermediate device being the same, thereby bypassing the auto-negotiation of the PCS sub-layer in the intermediate device. The intermediate device may transparently send negotiation messages from each node to the other during the link negotiation phase without interacting with those messages. Instead of the intermediate device, a single form pluggable (SFP) device may be connected between the two network nodes via optical or copper interfaces on the network side and via an SFP slot on the device side.

The present invention relates to a method of signalling in an Integrated Access and Backhaul (IAB) network. The method comprises signalling metrics from a parent IAB node to a child IAB node for association of the child IAB node with the parent IAB node. Information related to multiplexing capability and supported modes of operation is signalled from the child IAB node to the parent IAB node. An active mode of operation is determined at the child IAB node. Timing Advance (TA) for each active mode of operation, guard information for each active mode of operation, and exchanges for In-Band Full Duplexing (IBFD) mode of operation are signalled. Further, fallback capability of IAB nodes during presence of Self-Interference (SI) is also signalled.

A terminal is disclosed that includes a processor that, in case where frequency division duplex (FDD) is applied, controls a transmission of an uplink (UL) signal, in FDD, at a same timing as a UL transmission timing that is applied in time division duplex (TDD). The terminal also includes a receiver that receives a downlink control information (DCI), and a physical downlink shared channel (PDSCH) scheduled by the DCI. The terminal also includes a transmitter that transmits a HARQ-ACK in response to the PDSCH. The reception of the DCI and the transmission of the HARQ-ACK are allowed within one slot. In other aspects, a radio communication method, a base station, and a system are also disclosed.

Aspects of the disclosure relate to obtaining a duplex mode of a scheduled entity, selecting a downlink-uplink (DU) slot interpretation to be applied by the scheduled entity to a slot including a DU symbol based on the duplex mode of the scheduled entity, and transmitting the DU slot interpretation to the scheduled entity. The DU symbol may be configured to include a downlink transmission and an uplink transmission within a same carrier bandwidth. Other aspects relate to receiving a message, indicating that the slot is formatted with a DU symbol, selecting a DU slot interpretation to be applied to the slot including the DU symbol based on a duplex mode of the scheduled entity, and applying the DU slot interpretation to the slot. Other aspects, examples, and features are also claimed and described.

Memory management in communication networks is disclosed. The method includes generating a memory allocation trigger for an event based on an event type and estimating a memory size required by the event based on the event type of a user service and at least one configuration parameter. The event type includes a new user service request, a modified user service request, or a network event. The method includes allocating a memory section to the event based on the estimated memory size for the event of the user service and availability of memory blocks in a memory pool, the memory section comprises at least one memory block. The method includes verifying performance of the communication network. Verifying further includes receiving performance feedback for the communication network in response to allocating the memory section for the user service and modifying at least one of the set of configuration parameters.

Improved techniques are provided for managing and optimizing network resources and spectrum access in a Self-Organizing Network (SON). A Spectrum Access System (SAS) collects network-related information from a plurality of network sources, such as base stations and user equipments (UEs), to perform optimization and organization across different networks, network operators, and network technologies. In some embodiments, the SAS may use the network information and a Radio Environment Map to optimize TDD synchronization in the SON. In other embodiments, the SAS may use the network information to populate a global Neighbor Relation Table. The SAS also may use the network information to optimize one or more network parameters, such as Physical Cell Identities or Root Sequence Indexes, antenna parameters, transmit power levels, handover thresholds, channel assignments, and so on, for use in the SON. Advantageously, the SAS's optimized network parameters may be used to improve network performance, reduce signal interference, and adjust to network failures in the SON.

A method for initialization of a group of customer premises equipment devices (CPEs) during a training that registers capabilities of the CPEs is disclosed, wherein at least one CPE registers late to the training and cannot be registered. The method includes determining capabilities of the CPEs during a joining phase of the training, wherein it is determined whether a CPE device is capable of employing vectoring and placing in a hold status the at least one CPE that registers late by keeping a line active that is coupled to the at least one CPE. The method further includes providing another joining phase after the joining phase to register the at least one CPE that registers late.

A method for enhanced physical downlink control channel monitoring (PDCCH) includes determining a monitoring span for monitoring a PDCCH within a slot, the monitoring span having a start symbol and a duration that spans one or more symbols within the slot. At least one of a maximum number of blind decoding (BD) attempts or a maximum number of control channel elements (CCEs) for channel estimation is determined based on the monitoring span. The PDCCH is monitored within the monitoring span up to the at least one of the maximum number of BD attempts or the maximum number of CCEs.

Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

A method for waking up, from a low-power mode, a first communications node coupled to a second node via a first communication link, includes determining, while the first node is awake, a first transmission rate for transmitting data over the first link, storing the first rate at the second node, and selectively transmitting, from the second node to the first node, a first wake-up command at a symbol rate corresponding to the first rate. Where a third node is coupled to the second node via a second link, the method may further include determining, at the second node, while the third node is awake, a second transmission rate for transmitting data over the second link, storing the second rate at the second node, and selectively transmitting, from the second node to the third node, a second wake-up command at a symbol rate corresponding to the second rate.
