The present invention is applicable to the field of communications technologies.

Methods and apparatuses are described herein for a 5G system that deploys services providing optimizations and value add services based on delay tolerant data (DTD) exchanges between end devices and machine to machine (M2M) servers. In accordance with one embodiment, an apparatus may receive, from a second apparatus via the network, first information comprising a delay tolerant communication configuration comprising an identifier and a delay tolerant characteristic. The apparatus may receive, from a third apparatus, data in a plurality of data bundles that each comprises the identifier. The apparatus may process, based on the first information, the plurality of data bundles. The apparatus may route, based on the first information, the plurality of data bundles. The third apparatus may comprise a user equipment (UE).

A method and apparatus for transmitting a user equipment (UE) assistance information message in a wireless communication system is provided. Upon receiving N consecutive number of indications of early-out-of-synchronization/early-in-synchronization from a lower layer of the UE, the UE transmits the UE assistance information message including the early-out-of-synchronization/early-in-synchronization indication to the network, and starts a prohibit timer for prohibiting transmission of the UE assistance information message including the early-out-of-synchronization/early-in-synchronization indication to the network. Further, the UE cancels a prohibit timer, if running, for prohibiting transmission of a UE assistance information message including an early-in-synchronization/early-out-of-synchronization indication.

The disclosure relates to technology for assigning resources to user equipment for a beam failure recovery by a base station. The base station identifies a beam failure random access channel (BRACH) resource holding beam correspondence with a synchronization signal (SS) block resource covering the user equipment, and assigns the user equipment one or more BRACH preambles for each BRACH resource assigned to the user equipment, excluding the BRACH resource holding beam correspondence with the SS block resource covering the user equipment.

The present application discloses a method and a terminal device for wireless link monitoring. The method includes: starting, by a terminal device, a timer T310, when a number of out of sync (OOS) indications continuously received by the terminal device exceeds a first number N310; and determining, by the terminal device, whether to stop the timer T310 before the timer T310 expires, according to a number of in sync (IS) indications received after the timer T310 is started or according to a proportional relation between the IS indication and the OOS indication received after the timer T310 is started.

An out-of-synchronization determining method and apparatus are provided. The method includes: receiving, by a control network element, interference metrics sent by N base stations; determining, by the control network element based on the interference metrics, M first to-be-inspected base stations in the N base stations and/or neighboring stations of the N base stations; determining, by the control network element, P second to-be-inspected base stations, where the P second to-be-inspected base stations are base stations meeting a detection condition that are selected from the M first to-be-inspected base stations, and the detection condition is that a characteristic sequence broadcast by the first to-be-inspected base station at a specified position in a radio frame is not received by any neighboring station at the specified position; and determining, by the control network element, an out-of-synchronization base station in the P second to-be-inspected base stations.

In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.
