The present disclosure provides methods and systems for allocation of contention based data transmission (CBDT) resource blocks in a non-terrestrial network. The method comprises: determining if the CBDT resource blocks are to be configured for allocation to a plurality of user equipments (UEs) based on at least one of a plurality of parameters. The method comprises determining if a fixed number of CBDT resource blocks from the CBDT resource blocks are to be used for the allocation based on the determination using at least one of the plurality of parameters. The method comprises allocating a number of CBDT resource blocks in one of a fixed manner or a dynamic manner, wherein the number of CBDT resource blocks are allocated in the fixed manner, based on the fixed numbers of CBDT resource blocks being used for the allocation, and the number of CBDT resource blocks are allocated in the dynamic manner, based on the fixed numbers of CBDT resource blocks not being used for the allocation.

Provided are a random access method and device, a user equipment and a storage medium. The method includes: determining listen-before-talk (LBT) priority levels for performing an LBT mechanism corresponding to messages transmitted during a random access process, and/or LBT priority levels of an LBT mechanism corresponding to different physical random access channel (PRACH) formats; and transmitting the messages for random access by means of the determined LBT priority levels corresponding to the messages and/or LBT priority levels corresponding to different PRACH formats after successfully performing the LBT mechanism. In such a way, the problem of the need of optimizing random access for a user equipment in the related art is resolved, thereby optimizing random access and improving the random access success rate.

A method for enabling communication between a first network entity and a second network entity via at least two network flows includes: providing at least a first network flow and a second network flow of the first network entity; measuring, by a measuring unit associated with the first network entity, condition values of each of the at least two network flows; comparing the measured condition values of the at least two network flows to entries of a condition matrix; based on comparing the measured condition values to the entries of the condition matrix, selecting a mode for the first network entity out of an aggregation mode, a reliability mode, and a single-connectivity mode; and activating the selected mode.

Methods, systems, and devices are used to implement BFR, SL-RS for BFD, radio link monitoring, or frequency assisted beam failure recovery, among other things.

A wireless communications protocol for enabling legacy (non-EHT) stations (STAs) to operate on the conditional link of the Soft AP MLD. Legacy devices can connect and setup link connections on the conditional link, and the scheduler is configured to allow legacy STAs to use the conditional link if there is no IDC interference issue at the soft AP MLD. This enhanced protocol utilizes either a cooperative HCCA schedule created for simultaneous transmission and reception over the basic link and conditional link, or an adaptive polling-based scheduling performed for the conditional link in response to the link status of the basic link.
