Abstract:
Methods, apparatuses and computer readable media are described that analyze and communicate signaling messages between a mobile wireless device and a wireless access network to realize a circuit switched fallback (CSFB) procedure when the mobile wireless device is initially in a radio resource control connected mode with the wireless network. A set of information elements of a paging message is analyzed, and based on contents of the set of information elements and an internal state of the mobile wireless device, connections between the mobile wireless device and first and second wireless access networks are changed to realize the CSFB procedure.
Abstract:
A user equipment (UE) configured to connect to a network and operate in a carrier aggregation mode and a single carrier mode performs methods to select optimal component carriers. The methods include determining that a primary component carrier is operating less optimally than a secondary component carrier, sending an indication to the network that the primary component carrier is operating less optimally than the secondary component carrier, acquiring the secondary component carrier as a target primary component carrier and operating with the secondary component carrier as the target primary carrier component. In one exemplary embodiment, the indication is declaring a radio link failure (“RLF”) between the UE and the network. In another exemplary embodiment, the indication is a measurement report send to the network that triggers a handover procedure for the UE.
Abstract:
The disclosure describes apparatus and methods for communicating control plane data with a mobile device in a Long Term Evolution (LTE) network employing carrier aggregation. A network apparatus, such as an enhanced NodeB (eNodeB) or a mobility management entity (MME), can be configured to evaluate a measurement report (MR) received from a mobile device for one or more radio frequency (RF) conditions associated with a primary network cell and one or more RF conditions associated with a secondary network cell. Then, based on the evaluation, the network apparatus can determine to communicate the control plane data with the mobile device via the primary network cell, the secondary network cell, or both. The control plane data can correspond to non-access stratum (NAS) information, radio resource control (RRC) information, or a hybrid automatic repeat request (HARQ) retransmission of previously transmitted control plane data.
Abstract:
This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.
Abstract:
This disclosure relates to providing early packet delivery to radio link control. A transport block may be received by a wireless device via wireless communication. The transport block may fail a transport block cyclic redundancy check, but a subset of the code blocks of the transport block may pass code block cyclic redundancy checks. Packet data from the subset of the code blocks that pass code block cyclic redundancy checks may be provided to a radio link control layer of the wireless device, based at least in part on the successful code block cyclic redundancy checks for those code blocks.
Abstract:
This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.
Abstract:
Embodiments are presented herein of apparatuses, systems, and methods for mitigation of secondary cell failures. A user equipment (UE) may establish communication with a macro cellular base station. The UE may perform a signal quality measurement of a small cell base station and compare the signal quality measurement to a threshold. Based on the signal quality measurement exceeding the threshold, the UE may attempt to additionally connect to the small cell base station. In response to a radio link failure of the second base station, the UE may modify the first threshold. In response to subsequent failures to additionally connect to the small cell base station using the modified first threshold, the UE may disable connections to the small cell base station.
Abstract:
A base station may be configured to perform operations related to link management for a remote user equipment (UE). The operations comprising, transmitting configuration information to the remote UE and receiving information corresponding to a serving link associated with the remote UE. The operations further comprising determining that the serving link associated with the remote UE is to be switched from a first communication link to a second communication link. The operations further comprising, transmitting a message to the remote UE indicating that the serving link associated with the remote UE is to be switched from the first communication link to the second communication link. The operations further comprising, transmitting a message to a relay UE. The message is configured to trigger the relay UE to perform an operation corresponding to the serving link associated with the remote UE.
Abstract:
A network device or component such as an access node (AN) can operate to provide a request to obtain a network slice of a network slice as a service (NSaaS) to provide a communication service on the network slice for an end-user device. In response to obtaining the network slice, a network slice customer (NSC) Service identity (ID) associated with the network slice can be determined and provided for a communication service for an application by the end-user device or user equipment (UE). The request can be processed at a network slice provider (NSP) component, in which the network slice can be assigned to the NSC in response to the request by the NSC. The NSP further provides a user equipment (UE) route selection policy (URSP) comprising a traffic descriptor that includes the NSC Service ID to the NSC.

Apparatuses, systems, and methods for using an assistance information framework to perform fast carrier aggregation and dual connectivity configuration. A wireless device may provide assistance information for determining a carrier aggregation or dual connectivity configuration to a cellular base station. The assistance information may be provided while establishing a radio resource control connection. The assistance information may include either or both of carrier aggregation or dual connectivity preference information for the wireless device or service data amount information for the wireless device. The cellular base station may select a carrier aggregation or dual connectivity configuration for the wireless device based on the assistance information, and may provide configuration information for the selected configuration to the wireless device.
