Abstract: Embodiments of the present disclosure relate to methods and apparatuses for handover and reestablishment in a wireless communication system. According to some embodiments of the disclosure, a method may include: receiving, at a user equipment (UE), a radio resource control (RRC) reconfiguration message including a path switch indication and a list of candidate relays; selecting a target relay from the list of candidate relays; and establishing a PC5 RRC connection with the target relay. Furthermore, the UE may select another target relay for path switch if a path switch failure associated with the first selected target relay happens.

Abstract: The present application relates to a method and an apparatus for performing cell measurement process. One embodiment of the present disclosure provides a method performed by a method performed by a User Equipment (UE) in a wireless network with a variable coverage, comprising: performing a cell measurement process of one or more cells of the wireless network; and in response to a variation in the coverage of the wireless network in relation to the UE, disabling the cell measurement process of the one or more cells of the wireless network.

Abstract: The present invention is directed to solid-state composite cathodes that comprise Na2S or Li2S, Na3PS4, or Li3PS4, and mesoporous carbon. The present invention is also directed to methods of making the solid-state composite cathodes and methods of using the solid-state composite cathodes in batteries and other electrochemical technologies.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for path switch in a wireless communication system. According to some embodiments of the disclosure, a method may include: receiving, at a UE, an RRC reconfiguration message from a BS via a source Uu link, wherein the RRC reconfiguration message includes a path switch indication indicating a switch to a target relay; and in response to the RRC reconfiguration message, transmitting an RRC reconfiguration complete message to the BS via the target relay, initiating a reestablishment procedure over a Uu interface, or falling back to the source Uu link. The method may further include: in response to the RRC reconfiguration message, detaching or maintain the source Uu link.

Abstract: Embodiments of the present application are directed to a method and apparatus for configuring timers and performing data transmission in a SDT procedure. In an embodiment of the present application, the method includes: receiving configured grant (CG) resource configuration information on a plurality of CG resources from a base station (BS); and determining a value of timing alignment (TA) timer based on a period of one selected CG resource from the plurality of CG resources or based on a value configured by the BS; and transmitting data in at least one of the plurality of CG resources if the TA timer is running and the at least one of the plurality of CG resources is valid.

Abstract: Embodiments of the present application are related to a method and apparatus for data transmission. An exemplary method of the present application includes: generating a first physical data unit (PDU) based on first key information from a wireless network while a terminal device is in a non-connected state with the wireless network; receiving a second key information from the wireless network; generating a second PDU from the generated first PDU based on the second key information; and transmitting the generated second PDU within the wireless network.

Abstract: The present application relates to a method and an apparatus for fallback of data transmission. The method includes: detecting a trigger condition relating to a wireless network characteristic, while the user equipment is in a non-connected RRC state with a network device; and controlling a data transmission according to the detection of the trigger condition.

Abstract: The present invention discloses a novel double-valve continuous circulating valve with a clamping device, comprising a main through valve (5), a pup joint body (8), a middle connector (11) and a bypass valve (12); the main through valve seat (4), the main through valve (5) and the main through valve spring (6) are press-fitted in the pup joint body (8) through a main through valve limiting device (1); a bypass valve seat (10) is arranged at the lower side of the pup joint body (8), and the bypass valve (12) is mounted and fixed to the bypass valve seat (10) through a bypass valve limiting device (9); the middle connector (11) is press-fitted on the pup joint body (8) through a clamping device. The present invention solves the technical problems of dangerous incidents caused by the suspension of circulating medium.
