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.

Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A UE receives a system information block (SIB) from a base station. The UE obtains a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration from the SIB. The UE identifies DL subframes in a radio frame. The UE monitors the PDCCH transmitted from the base station on a DL subframe included in an on duration period of a discontinuous reception (DRX) cycle. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE applies the second TDD UL/DL configuration to the radio frame. The DL subframe corresponds to a predetermined subframe number in the radio frame. The on duration period represents a period corresponding to a predetermined number of subframes from a subframe where the DRX cycle starts, and the on duration period is repeated periodically.

A method and an apparatus are provided for monitoring a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system. The UE receives a system information block (SIB) from a network. The UE identifies at least one downlink (DL) period based on a first time division duplex (TDD) uplink (UL)/DL configuration included in the SIB; monitoring, by the UE, the PDCCH during the at least one DL period using a discontinuous reception (DRX) operation. The UE obtains information about at least one second TDD UL/DL configuration for one or more time intervals from the monitored PDCCH. The monitoring of the PDCCH comprises monitoring the PDCCH in an active time of a DRX cycle. The active time includes a time when the UE performs continuous reception.

The present disclosure relates to a method used in a BS and an associated BS. The method includes: obtaining one or more dynamic UpLink (UL)/Downl_ink (DL) configurations of a cell served by the BS; transmitting, to a User Equipment (UE) located in the cell, the one or more dynamic UL/DL configurations in a resource region consisted of one or more consecutive Control Elements (CEs) over a downlink physical channel; and transmitting information associated with the resource region to the UE. The present disclosure also relates to a method used in a UE located in a cell served by a BS and an associated UE. The method includes: receiving, from the BS, one or more dynamic UL/DL configurations of the cell in a resource region consisted of one or more consecutive CEs over a downlink physical channel; receiving information associated with the resource region from the BS; and identifying the one or more dynamic UL/DL configurations based on the information associated with the resource region.

A method and an apparatus are provided for monitoring a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system. The UE receives a system information block (SIB) from a base station.

A method of a second node for a co-existence operation in a wireless communication system is provided. The method comprises transmitting, to a first node, a first extended schedule element (ESE) frame including a time-division multiplexing service period (TDD-SP) bit, receiving, from the first node, a preamble or a second ESE frame including a short device co-existence (SRD Co-Ex) indicator that is set to one based on the TDD-SP bit, and changing a transmit-receive slot pattern based on the received preamble or SRD Co-Ex indicator for the co-existence operation.

Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating a configuration of slot formats for a plurality of time periods. The UE may receive an indication of one or more time locations, with respect to the plurality of time periods, for sub-band full duplex (SBFD) communication at a network node or for reverting from SBFD communication to half-duplex communication at the network node. Numerous other aspects are described.
