    Abstract: A system and method for channel access in licensed and unlicensed spectrums are disclosed herein. In one embodiment, a method performed by a communication node, includes: detection of an idle channel associated with a communication device after performance of a channel access procedure; transmitting an initial signal after the detection of the idle channel, wherein the initial signal configures a communication device to start detecting a control channel; and transmitting a control signal using the control channel to the communication device after the transmitting the initial signal.

    Abstract: This patent document describes, among other things techniques for determining when to switch between a channel access procedure that includes a listen before talk (LBT) process and a channel access procedure that does not include a LBT process. In one aspect, a method of wireless communication is disclosed. The method includes receiving, by a first network node from a second network node, a message specifying a first channel access procedure to be used by the first network node after being powered up. The method further includes selecting, by the first network node, a second channel access procedure to be used after the first channel access procedure after satisfying a condition, wherein if the condition is not satisfied the first network node continues to use the first channel access procedure.

    Abstract: 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.

    Abstract: Methods, apparatus, and systems that relate to reference signal measurement and reporting at a lower layer to enable fast cell switching include a method for wireless communication includes transmitting, by a network node, configuration information about one or more candidate targets to a terminal device to enable a measurement or a reporting of the one or more candidate targets, e.g., at a layer that is lower than the network layer. The configuration information comprises at least one of measurement configuration or reporting configuration about the one or more candidate targets, the configuration information further comprising inter-frequency information.

    Abstract: The present disclosure describes methods, systems and devices for transmitting initial access information from a base station to a user equipment (UE). One method includes notifying, by the base station, the UE to support at least one subcarrier spacing (SCS); communicating, by the base station, a subcarrier offset to the UE; and configuring, by the base station, a multiplexing pattern between initial access information. Another method includes receiving, by the UE from the base station, notification to support at least one subcarrier spacing (SCS); receiving, by the UE from the base station, a communication comprising a subcarrier offset; and receiving, by the UE from the base station, a configuration for a multiplexing pattern between initial access information.
