Systems and methods are disclosed for a WTRU to operate using multiple schedulers. The WTRU may exchange data with the network over more than one data path, such that each data path may use a radio interface connected to a different network node and each node may be associated with an independent scheduler. For example, a WTRU may establish a RRC connection between the WTRU and a network. The RRC connection may establish a first radio interface between the WTRU and a first serving site of the network and a second radio interface between the WTRU and a second serving site of the network. The RRC connection may be established between the WTRU and the MeNB and a control function may be established between the WTRU and the SCeNB. The WTRU may receive data from the network over the first radio interface or the second radio interface.

An in-vehicle relay apparatus provided on a roof of a vehicle includes: a first connector connected to a power line and a communication line provided on one pillar of the vehicle; a second connector to which a power line and a communication line provided on a different pillar are connected; a branch line connector to which power lines and communication lines extending from a plurality of in-vehicle devices provided on the roof are connected; a branching portion branching a single wire system into power lines connected to the branch line connector, the single wire system being a system in which the power lines respectively connected to the first connector and the second connector are integrated into one system; and a relay unit relaying data passing between the communication lines connected to the first connector and the second connector and the communication lines connected to the branch line connector.

A random access method and apparatus and resource configuration method and apparatus. The random access apparatus includes: a third receiving unit configured to, on a physical random access channel resource, receive a random access preamble transmitted by a terminal equipment; wherein the random access preamble is used to indicate that the terminal equipment has sidelink data to be transmitted, and/or the physical random access channel resource is used to indicate that the terminal equipment has sidelink data to be transmitted; and a second transmitting unit configured to transmit a random access response to the terminal equipment. By indicating in the random access procedure to the network device that the terminal equipment has a sidelink MAC CE to be transmitted, it may be avoided that the network device does not learn that the terminal equipment has a sidelink MAC CE to be transmitted, so that the network device allocates resources for the sidelink, and resource consumption may be lowered.

Certain aspects of the present disclosure provide techniques for sidelink communications in an unlicensed spectrum. A method that may be performed by a user equipment (UE) and a base station (BS) includes sensing, prior to a start of a time window, a frequency band to determine whether the frequency band is idle, the time window divided in time into a plurality of time periods, the frequency band divided in time across multiple of the plurality of time periods into a corresponding plurality of resources comprising one or more unassigned resources and one or more assigned resources assigned to one or more other wireless communication devices for wireless communication.

A method for wireless communication includes transmitting, by a User Equipment (UE) in a Radio Resource Control (RRC) Inactive (RRC_Inactive) state, at least one packet to a base station, and receiving, by the UE in the RRC_Inactive state, an acknowledgement or non-acknowledgement (ACK/NACK) message from the base station in response to the at least one packet transmitted by the UE.

This disclosure provides systems, methods and apparatuses for advertising discovery information of an AP in one or more downlink (DL) transmissions. In some implementations, the AP may allocate a dedicated resource unit (RU) for advertising discovery information of the AP to stations not associated with the AP, and may allocate one or more additional RUs for DL transmissions to one or more stations associated with the AP. The AP may transmit a multi-user (MU) packet containing discovery information intended for the unassociated stations and containing non-discovery-related information intended for the one or more associated stations. The discovery information may be transmitted on the dedicated RU, and the non-discovery-related information may be transmitted on the one or more additional RUs.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides method and apparatus of performing random access procedure.
