Abstract:
Examples are disclosed for facilitating dual connectivity for user equipment (UE) in a wireless network. The examples include establishing a backhaul link between base stations serving as primary and secondary cells for separate UE connections to management or gateway entities for the wireless network. The primary base station may provide macro cell coverage for the one or more UEs while the secondary base station may provide small cell coverage. The two base stations may split at least some protocol stack processing for radio bearers associated with the separate UE connections. Control information may be exchanged through the backhaul link to facilitate the split protocol stack processing. Other examples are described and claimed.
Abstract:
Embodiments of an Evolved Node-B (eNB) to support packet-switched (PS) services according to EPS bearers are disclosed herein. The eNB may receive an EPS bearer setup message from an MME for an establishment of an EPS bearer for a PS service between a User Equipment (UE) and a PGW. The EPS bearer setup message may include an attention indicator for the PS service that indicates whether traffic for the PS service is attended or unattended at the UE. The eNB may further transmit traffic packets to and receive traffic packets from the UE 102 as part of the PS service. In addition, the eNB may use the attention indicator as part of congestion control in the network.
Abstract:
Embodiments of the present disclosure describe systems, devices, and methods for load balancing in a wireless communication network based on user equipment (UE) mobility. In embodiments, a UE may receive a plurality of cell reselection priority configurations designated for different levels of UE mobility. The UE may determine its mobility and select one of the cell reselection priority configurations based on the determined mobility. The UE may establish a radio resource control (RRC) connection, such as an RRC idle mode connection, on a carrier frequency and/or cell based on the selected cell reselection priority configuration. Other embodiments may be described or claimed.
Abstract:
Various embodiments may be generally directed to techniques for configuring a secondary RF chain of a mobile device—in particular, a secondary receiver chain—to perform wireless network measurements when the secondary RF chain is not used for data communications. Various embodiments provide for a primary RF chain to provide data communications with a wireless network and for the secondary RF chain to be capable of providing aggregated data communications with the wireless network. Various embodiments provide for the mobile device to determine that the wireless network does not support carrier aggregation and to reconfigure the secondary receiver chain, which would otherwise be left unused or inactive, to perform wireless network measurements. System throughout can be improved in comparison to using the primary RF chain for performing the wireless network measurements.
Abstract:
Embodiments of a User Equipment (UE) to support inter-frequency handover are disclosed herein. The UE may receive, from an Evolved Node-B (eNB), a measurement report configuration message that includes multiple measurement events to be determined at the UE. The UE may transmit a measurement report when a combined measurement event occurs. The combined measurement event may include a combination of the multiple measurement events according to a “logical AND” operator such that the combined measurement event occurs when the multiple measurement events occur. The measurement events may be related to signal measurements performed on one or more signals received at the UE from one or more cells configured for operation in the network.
Abstract:
Systems, methods, and device for adjusting an operation time of a radio link failure timer are disclosed herein. User equipment (UE) may be configured to communicatively couple to an evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE use different radio link failure timer parameters depending on the speed of the UE. The radio link failure timer may run for a longer time for rapidly moving UEs and run for a shorter time for slowly moving UEs. In an embodiment, the UE may scale the radio link failure timer by a scaling factor. In another embodiment, the UE may include multiple radio link failure timers for different speeds. The radio link failure timer parameters for each speed may be specified by the E-UTRAN in a one-to-one communication. The E-UTRAN may determine which parameters to use for each UE based on characteristics of the UE.
Abstract:
Embodiments of the present disclosure describe systems, devices and methods for system information acquisition in radio resource connection (RRC) connection reestablishment when Radio Link Failure (RLF) happens. Various embodiments may include a serving cell that provides system information of a neighbor cell to a user equipment (UE). When the UE detects an RLF event, the UE may determine whether the previously received system information is valid and proceed with RRC connection reestablishment based on the determination. Other embodiments may be described or claimed.
Abstract:
Technology for using an open mobile alliance (OMA) management object (MO) for congestion control in mobile networks is described. A novel type of OMA MO for application specific access control (ASAC) can include internet protocol (IP) flow descriptions that can be used to characterize applications with fine granularity. Priorities can be assigned to IP flows based on the IP flow descriptions. A user equipment (UE) can receive such an OMA MO and also receive application-barring information regarding a congestion level in a mobile network with which an application at the UE wishes to connect. The UE can have a connectivity manager (CM) that determines whether to allow the application to establish a connection with the mobile network based on the priority level of the application's associated IP flow and the application-barring information.
Abstract:
Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication in accordance with a packet convergence and link control (PCLC) layer are generally described herein. The UE may receive, from a Fifth Generation (5G) eNB, a first group of medium access control (MAC) protocol data units (PDUs) that include PCLC PDUs. In accordance with PCLC sequence numbers (SNs), the UE may reorder the PCLC PDUs and may decipher the PCLC PDUs. The UE may receive, from a legacy eNB, a second group of MAC PDUs that include packet data convergence protocol (PDCP) PDUs encapsulated in radio link control (RLC) PDUs. The UE may reorder the RLC PDUs based on RLC SNs and may decipher the RLC PDUs based on PDCP SNs that are exclusive to the RLC SNs.
