A network entity for a mobile telecommunications system, including circuitry configured to perform an admission control of a received connection request to the mobile telecommunications system, wherein the admission control is performed based on a plurality of admission control layers.

Systems, methods and instrumentalities are described herein with respect to the mobility and multi-connectivity of wireless transmit receive units. These devices may be configured to perform conditional handovers and/or conditional second cell group reconfigurations including primary secondary cell additions or changes. The devices may exchange information with a network while performing the conditional reconfigurations and/or conditional handovers. The devices may be configured with rules to handle concurrent handover and reconfiguration tasks.

A method for information reporting, user equipment, and a network side device are provided. The method includes: reporting target discontinuous transmission or reception information of at least one carrier to a target device, where the target discontinuous transmission or reception information is used to indicate discontinuous transmission or reception information of a target discontinuous transmission or reception mode of second UE; the target discontinuous transmission or reception mode includes at least one of the following: a first Uu discontinuous transmission or reception mode, a second Uu discontinuous transmission or reception mode, or a sidelink discontinuous transmission or reception mode, where the second Uu discontinuous transmission or reception mode is a Uu discontinuous transmission or reception mode used by UE with a first sidelink resource allocation mode.

A base station transmits configuration parameters indicating a first position and a second position. The first position may be in a first number of bit. The second position may be in a second number of bit. The first number of bit and the second number of bit may be based on a payload size. The base station may transmit cancellation indications comprising a first cancellation indication. The first cancellation indication may indicate cancellation of a scheduled transmission. The first cancelation indication may be based on the first position when the scheduled transmission is for a normal carrier and may be based on the second position when the scheduled transmission is for a supplementary carrier.

A user equipment is disclosed including a receiver that receives an RRC message related to configuration information of a second radio base station for a split hearer that splits from the second radio base station toward a first radio base station, and a processor that releases resources related to a radio link of the second radio base station based on the RRC message when a radio link failure in the second radio base station is detected.

A method, apparatus and computer program product are provided herein to provide a Protocol Data Unit (PDU) session priority parameter. For example, a method is provided that comprises identifying a need in a user equipment (UE) for establishing a new protocol data unit PDU session. The method also includes evaluating whether to establish a new PDU session and determining whether to establish a new PDU session based on a PDU session priority parameter when a maximum number of PDU sessions the UE can establish in the network is reached.

In a band sharing communication system in which there are a primary system and a secondary system in descending order of priority of communication, the systems share frequency bands, and a base station or a line control device performs allocation of a requested band of a terminal station of each system, the base station or the line control device including: occupied band setting means for setting a primary occupied band and a secondary occupied band adjacent to the primary occupied band; band allocation means for allocating a vacant band of the primary occupied band with respect to a requested band of a primary terminal station and allocating a vacant band of the secondary occupied band with respect to a requested band of a secondary terminal station; and band transferring means for, when there is no vacant band in the primary occupied band with respect to a requested band of the primary terminal station, transferring a band of the secondary occupied band from the secondary occupied band to the primary occupied band and allocating the band to the primary terminal station, said band being adjacent to the primary occupied band and equivalent to the requested band. The secondary terminal station is configured to, when the secondary terminal station is performing communication in the band equivalent to the requested band and being transferred from the secondary occupied band to the primary occupied band and detects degradation in communication quality due to interference with the primary terminal station, suspend said band and provide the band to the primary terminal station.
