A transmission method and apparatus for a wireless network, a communication node and a non-transitory computer-readable storage medium are disclosed. The transmission method for a wireless network may include: receiving a physical-layer protocol data unit (PPDU) which carries first identifier information; and keeping a locally stored network allocation vector (NAV) unchanged, or updating the locally stored NAV and ignoring the updated NAV in a process of multi-access point transmission.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives one Downlink Control Information (DCI) for scheduling two Physical Downlink Shared Channels (PDSCHs); and a control section that determines one or two Quasi Co-Locations (QCL) parameters for the two PDSCHs based on whether or not presence of a Transmission Configuration Indication (TCI) field is configured. According to one aspect of the present disclosure, it is possible to appropriately determine QCL parameters for multiple panels/TRPs.

A terminal according to one aspect of the present disclosure includes: a control section that derives a Quasi-Co-Location (QCL) assumption of an Aperiodic Channel State Information-Reference Signal (A-CSI-RS) based on a specific Transmission Configuration Indication state (TCI state) for a Physical Downlink Shared Channel (PDSCH) in a case where both of following conditions (1) and (2) are satisfied, where (1) a scheduling offset between reception of a downlink control channel for conveying downlink control information for scheduling the A-CSI-RS, and reception of the A-CSI-RS is less than a reported value of a duration for beam switch, and (2) there is not another downlink signal that includes an instructed TCI state or there is another downlink signal that does not include the instructed TCI state in a same symbol as a symbol of the A-CSI-RS; and a receiving section that receives the A-CSI-RS based on the QCL assumption.

A TSN-based distributed antenna system including a headend unit, one or more TSN switches, and one or more remote units and a fronthaul transport network constituted by the headend unit, the TSN switch, and the remote unit is provided. The packet-based fronthaul network constituted by the headend unit, the TSN switch, and the remote unit transmits traffic in a time-deterministic manner while minimizing packet loss through Ethernet to which TSN standards are applied.

Aspects described herein relate to receiving, at a repeater and from a serving base station, one or more transmitted downlink beams, receiving, at the repeater and from a downstream node served by the serving base station, one or more transmitted uplink beams, and transmitting, to the serving base station, one or more parameters related to determining a channel quality metric using at least the one or more transmitted downlink beams and the one or more transmitted uplink beams.

The disclosure provides a method of operating a distributed antenna system (DAS) interworking with a spectrum sharing system (SSS) including: transmitting, by a node unit of the DAS, DAS information to a management system entity (MSE); generating, by the MSE, linkage information based on the DAS information and radio service device (RSD) information received from at least one RSD of the SSS; transmitting, by the MSE, the interworking information to a system controller of the SSS; receiving, by the MSE, allocation information including a result of allocating shared radio resources to the DAS and the at least one RSD, respectively, according to the interworking information from the system controller; transmitting, by the MSE, the allocation information to the node unit; and operating, by the node unit, according to the allocation information.
