Abstract:
A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) lay er. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.
Abstract:
Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine that the UE is in an Inactive Radio Resource Control (RRC) state. The second circuitry may be operable to process a first transmission received by the UE while the UE is in the Inactive RRC state, the first transmission carrying a set of one or more Access Control (AC) parameters. The third circuitry may be operable to regulate the sending of a second transmission, in accordance with the set of one or more AC parameters, while the UE is in the Inactive RRC state.
Abstract:
Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example, a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.
Abstract:
An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured determine repetition level (RL) thresholds, allocate downlink resources, wherein the downlink resources include a repetition level (RL), send downlink data to the RF interface for transmission to a user equipment (UE) according to the RL, receive repetition feedback from the RF interface based on the transmission to the UE, and update the downlink resources based on the repetition feedback.
Abstract:
Described is an apparatus of a User Equipment (UE) operable to communicate with a first Evolved Node B (eNB) and a second eNB on a wireless network. The apparatus may comprise a first circuitry, and a second circuitry. The first circuitry may be operable to generate a security token. The second circuitry may be operable to generate a Radio Resource Control (RRC) message for transmission to the first eNB, in response to the UE detecting a Radio Link Failure (RLF) in communication with the second eNB, the RRC message comprising the security token.
Abstract:
Technologies described herein enable service providers to remotely provision, connect, and/or manage radio/network access for the CIoT devices (e.g., low-power, stationary CIoT devices that do not generally roam and are generally immobile) while making efficient use of radio resources and using robust end-to-end (E2E) security. A Radio Access Network Security Gateway (RAN-SecGW) associated with a cellular base station can have an Internet Packet (IP) secure tunnel to an Application Server (AS) of a Cloud Service Provider (CSP) and can maintain a mapping table in order to facilitate establishment of secure communications between the AS and a CIoT device without establishment of a full Radio Resource Control (RRC) connection and without the aid of a core cellular network.
Abstract:
Devices and methods of enhanced coverage (EC) paging are generally described. An evolved Node-B (eNB) may transmit multiple EC paging messages to user equipment (UE) over at least one paging cycle. Each EC paging message may contain the same paging information. The UE may combine the individual EC paging messages to achieve a predetermined link budget and subsequently may decode the EC combined paging message to determine whether the combined paging message is directed to the UE. The EC paging messages may contain information for more than one UE and a legacy P-RNTI or a specific P-RNTI for EC mode UEs. The EC paging messages may be transmitted in legacy occasions over several paging cycles or non-legacy paging occasions over one or more paging cycles. The EC paging messages may be transmitted in continuous or non-continuous subframes in a particular paging cycle.
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 assistance 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:
Embodiments of a Mobility Management Entity (MME) to support packet-switched (PS) services in a network in accordance with Evolved Packet System (EPS) bearers are disclosed herein. The MME may receive, from a User Equipment (UE), an indicator of Machine Type Communication (MTC) operation, which may indicate that the UE operates as an MTC UE. The MME may, at least partly in response to a determination of UE inactivity on an EPS bearer, transmit a bearer release message for release of an S5/S8 bearer included in the EPS bearer. In some embodiments, the indicator of MTC operation may include a permission indicator from the UE for the release of the S5/S8 bearer. In some embodiments, the indicator of MTC operation may include an indicator of transmission of small blocks of data or transmission at an infrequent rate.
