Various embodiments relate to a method for a non simultaneous transmit and receive (NSTR) soft access point (AP) multi-link device (MLD) negotiating a traffic identifier (TID)-to-link mapping with a non-AP MLD, including: transmitting, by the NSTR soft AP MLD, a first frame that includes information on a first group of links that the NSTR soft AP MLD proposes to map to a first TID for the non-AP MLD, wherein the first group of links includes a first link from a first set of links, wherein the first set of links is a set of links on which APs affiliated with the soft AP MLD operates and non-EHT STAs or single link STAs can associate with the APs; receiving, by the NSTR soft AP MLD, a second frame that includes an indication that the non-AP MLD agrees with the NSTR soft AP MLD's proposal on mapping of the first TID to the first group of links; determining, by the NSTR soft AP MLD, that traffic to the non-AP MLD has a first the first TID that is mapped to the first group of links; and transmitting, by the NSTR soft AP MLD, the traffic to the non-AP MLD on the first group of links.

A serial bidirectional communication method is provided. The method includes: performing a downlink transmission and performing an uplink transmission. The downlink transmission includes: receiving first downlink data through a first transmission terminal, wherein the first downlink data comprises at least one control command, and the at least one control command is cascaded and configured to control at least one electronic device; removing one, corresponding to a local device, of the at least one control command from the first downlink data to form second downlink data, wherein the local device is one of the at least one electronic device; and when there is a control command remaining in the second downlink, outputting the second downlink data through a second transmission terminal. The uplink transmission includes outputting first uplink data through the first transmission terminal. The first uplink data includes local information generated by the local device.

A method of handling a remote interference (RI) between base stations of a time division duplex (TDD) network is provided. The method comprises or initiates a step of determining a set of radio resources for reference signals (RSs) for handling the RI. The method further comprises or initiates a step of handling the RI by at least one of transmitting and receiving one or more RSs using the radio resources of the determined set.

Methods and apparatus for supporting communication, discovery, and use of time division duplex (TDD) configuration information between nearby cells are described. A first base station requests a UE to collect and report back TDD configuration information about another base station, e.g., a neighboring base station, from which the UE receives signals, e.g., broadcast signals above a predetermined signal strength threshold. In some embodiments, the requests are qualified based on one of more of: i) inter or intra operator network, ii) radio access technology (RAT) in use, or iii) frequency band. The first base station utilizes reports, communicating TDD configuration information pertaining to nearby base stations, obtained from one or more UEs, to manage interference, e.g., changing the first base station's current TDD configuration settings, generating a new first base station TDD configuration, and/or deciding whether or not to use a frequency band of shared and/or unlicensed spectrum or licensed spectrum.
