Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a primary user equipment (UE) may transmit, on a sidelink, information indicating a set of sidelink random access configurations corresponding to a set of uplink random access configurations; receive, on the sidelink and from a secondary UE, a random access signal based at least in part on a selected sidelink random access configuration of the set of sidelink random access configurations, wherein the selected sidelink random access configuration corresponds to a selected uplink random access configuration of the set of uplink random access configurations; and selectively performing a random access procedure in accordance with the selected uplink random access configuration. Numerous other aspects are provided.

Disclosed are a method and apparatus for performing a random access procedure in a wireless communication system. The method for performing a random access procedure according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, configuration information related to random access, wherein the configuration information includes a scaling factor for a back-off indicator (BI) for a specific type of terminal; transmitting a first random access preamble to the base station; receiving, from the base station, a random access response (RAR) in response to the first random access preamble, wherein the RAR includes the BI; and on the basis of the RAR not including a random access preamble identifier (RAPID) associated with the first random access preamble, transmitting a second random access preamble to the base station.

The apparatus includes at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to duplicate base station computation of an identifier value for a user equipment, and search for one or more control channel transmissions incorporating an identifier value matching the identifier value.

The present application discloses a method and a device for wireless communications, comprising: receiving a first signaling; and transmitting a first signal; herein, the first signaling is used to indicate a first identifier and a second identifier; the first identifier and the second identifier are both used to determine the first node; the first signal carries a target identifier, the target identifier being either the first identifier or the second identifier; when the target identifier is the first identifier, the first signal carries a first message; when the target identifier is the second identifier, the first signal carries a second message; a first logical channel is used for bearing the first message. The present application determines the target identifier in a rational way to enhance the resource utilization ratio.

Disclosed is a random access method and apparatus for a reduced capability user equipment in a wireless communication system. A method of performing random access by a UE in a wireless communication system according to an embodiment of the disclosure may include an operation of receiving random access-related configuration information from a base station; an operation of determining at least one of a RACH occasion (RO) group related to random access preamble transmission, one or more ROs, and a random access preamble group based on at least one of the random access-related configuration information, a UE type, and a repetition level; and an operation of transmitting one or more random access preambles in each of the one or more ROs.

Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-of-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-of-COT resources. The UE may then transmit to a second UE using the set of transmission resources.

A mobile station in a wireless communication network. The mobile station includes a radio communication that transmits an access request message to a base station via a first communication resource, and receives a timing adjustment in response to the access request message from the base station. The mobile station also includes an adjustment value storage unit that stores the timing adjustment, and a control unit that adjusts access timing corresponding to a second communication resource based on the timing adjustment value stored in the adjustment value storage unit. The radio communication unit then communicates with the base station via the first communication resource and the second communication resource.

An apparatus may control the power delivered from an AC power source to an electrical load, and may comprise a controllably conductive device. The apparatus may also comprise a controller that may be operatively coupled to a control input of the controllably conductive device. The apparatus may also include a first wireless communication circuit operable to communicate via a first protocol and to join a first wireless communication network operable to communicate via the first protocol. The first wireless communication circuit may be in communication with the controller. The controller may be operative to determine a first condition for communicating via the first protocol. The controller may also be operable to control the first wireless communication circuit to join the first wireless communication network upon the first condition being satisfied.

The present invention relates to a wireless communication method for power saving and a wireless communication terminal using the same, and more particularly, to a wireless communication method for efficiently conducting data transmission/reception of each terminal in a high density environment and a wireless communication terminal using the same. To this end, the present invention provides a wireless communication method for a terminal including receiving a distributed access group parameter for data transmission/reception by a group unit, wherein the distributed access group parameter comprises information about a number of groups assigned to a corresponding BSS, obtaining group information about the terminal based on the distributed access group parameter, and performing data transmission based on the obtained group information, and a wireless communication terminal using the same.

In one aspect, a wireless device receives a scheduling grant and a grant confirmation signal indicating that a network node has performed a CCA on a carrier and is releasing the carrier for the wireless device. An uplink message is transmitted on the carrier without performing a CCA on the carrier. In another aspect, a wireless device is connected to a first cell and a second cell configured on a carrier requiring an LBT protocol. The wireless device receives configuration messages indicating that downlink transmissions on the second cell are to be scheduled. This can mean self-scheduling for downlink on the second cell and cross-carrier scheduling for uplink on the first cell. The wireless device receives a scheduling grant in the first cell and performs a CCA in the second cell. The wireless device then transmits an uplink message responsive to success of the CCA.
