Abstract:
Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in RRC_IDLE state of wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having processing circuitry arranged to determine to use an extended paging discontinuous reception (DRX) value to increase a paging cycle length. The wireless communication device may transmit a non-access stratum (NAS) message to the network, indicating that the wireless communication device desires to use the extended paging DRX value. The wireless communication device may receive a message from the network that includes an information element (IE) indicating whether the network supports the extended paging DRX value. Other methods and apparatuses are also described.
Abstract:
Briefly, in accordance with one or more embodiments, a user equipment (UE) may enter into an E-UTRAN Routing Area Paging Channel state, and is configured with an E-UTRAN Routing Area and an Anchor identifier to identify an anchor evolved Node B (eNB) for the UE. The UE selects to a new cell without performing a handover procedure, and performs a cell update procedure. The UE also may enter into a Cell Update Connected state, and is configured with an Anchor identifier. The UE selects to a new cell, performs a cell update procedure, performs a buffer request procedure, and performs a cell update procedure to download buffered data and to perform data transmission with the new cell.
Abstract:
Apparatuses and methods for control of small data transmission by a user equipment (UE) are described herein. The UE may determine that data to be transmitted by the UE is small data if a size of the data is below a threshold. The UE may transmit a message indicating that the UE shall be transmitting small data responsive to determining that data to be transmitted by the UE is small data. The UE may receive a radio resource control (RRC) signal from an evolved Node B (eNodeB) that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) configured for transmission of small data. The UE may transmit small data on the SDRB subsequent to receiving the RRC signal from the eNodeB. The UE may refrain from transmitting other than small data on the SDRB. Other apparatuses and methods are described.
Abstract:
Technology for providing core network assistance information from a mobility management entity (MME) in an evolved packet core (EPC) is disclosed. An average radio resource control (RRC) connected state time for a UE is determined. An average RRC idle state time for the UE is also determined. An amount of time that the UE spends in cells of the EPC is identified to determine a number of handover procedures between cells in a selected time period. The core network assistance information communicated to a serving eNB of the UE to enable the serving eNB to reduce UE state transitions for the UE.
Abstract:
An evolved NodeB (eNB), user equipment (UE) and mobility management entity (MME), as well as method of communicating using a power saving mode (PSM) are generally described. A PSM configuration indication of the UE may be received at the eNB from the UE or MME in an Initial UE Context Setup Request, a UE Context Modify Request, core network as-eNB MME sistance information, or a dedicated message to the eNB. The eNB may adjust the time for transmitting to the UE an RRC connection release message based on the PSM configuration indication. The eNB may determine whether the UE is in a connection mode and the inactivity timer of the eNB having reached the activation timer of the PSM configuration indication, transmit the RRC connection release message to the MME. The PSM configuration may be provided between eNBs during handover.

Abstract:
Technology for a mobility management entity (MME) operable to provide core network assistance information is disclosed. The MME can determine the core network assistance information. The core network assistance information can include one or more of: an average connected state time for a user equipment (UE), an average idle state time for the UE, or a number of handover procedures between cells that occur for the UE in a selected time period. The MME can encode the core network assistance information for transmission from the MME to an eNodeB of the UE.
