Abstract: A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, perform a two-step or four-step random access procedure, and monitor a PDCCH according to a DRX configuration, wherein the PRACH transmitted in the random access procedure is transmitted on a specific RO from among a plurality of ROs, and a starting RB index of the specific RO can be determined on the basis of (i) the lowest RB index of an RB set including the specific RO, (ii) the starting RB index of an RO positioned at the lowest frequency, and (iii) the lowest RB index of an RB set including the RO positioned at the lowest frequency.

Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

Abstract: In one embodiment, a particular device in a deterministic network performs classification of one or more packets of a traffic flow between a source and a destination in the deterministic network.

Abstract: The present disclosure relates generally to the field of wireless communications, and in particular to techniques for efficiently transferring, among network nodes, an access context required to initiate data transfer when a user equipment (UE) is in an active or suspended Radio Access Network (RAN) connection state. The techniques disclosed herein involve identifying, based on UE-specific data (such, for example, as mobility information, a traffic profile), one or more relevant network nodes where the UE in the suspended RAN connection state could be located at the time when next data transfer needs to be initiated. After that, the access context is sent from an anchor network node to said one or more relevant network nodes. By sending the access context in this manner, network signalling overhead and storage capacity overhead may be significantly reduced.
