Abstract:
An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).
Abstract:
Certain embodiments described herein use variable RTT for HARQ operations. Uplink HARQ may include, for example, for a first synchronous HARQ process, a UE selects first downlink resources to monitor for first HARQ feedback based on the first HARQ RTT value, and generates a first HARQ retransmission for first uplink resources in response to the first HARQ feedback. For a second synchronous HARQ process, the UE select second downlink resources to monitor for second HARQ feedback based on the second HARQ RTT value, and generates a second HARQ retransmission for second uplink resources in response to the second HARQ feedback. In certain embodiments, a RAN node signals or indicates the variable RTT values to the UE.
Abstract:
A user equipment (UE) is configured to send a request to use an enhanced power saving mode (ePSM) to a mobility management entity (MME) of a mobile communications network. The UE is configured to receive configuration parameters from the MME including a time length for an idle mode and a time length for a power saving mode. The UE is configured to cycle between the idle mode and the power saving mode based on the power saving mode parameters, wherein the UE is available to receive transmissions during the idle mode and unavailable to receive transmissions during the power saving mode.
Abstract:
Technology described herein provides carrier-monitoring (CM) signaling approaches that can be used by networks and/or mobile devices. An evolved Node B (eNB) can send an IncMon-support message indicating whether a network supports the increased-number-of-frequencies-to-monitor (IncMon) feature. A UE can apply a default CM configuration if the UE does not receive an IncMon-support message from the eNB. The eNB can use dedicated signaling or broadcast signaling to inform a UE of a default CM configuration or one or more adopted CM configurations that are used in the network. The eNB can also send a list of carriers that are to be monitored to the UE. The UE can also send UE-capability information to the eNB, such as a default CM configuration, an adopted CM configuration, or configurable configurations in different radio access technologies (RATs) supported by the UE.
Abstract:
A user equipment having varied cell barring times is disclosed. The system includes circuitry and a control unit. The circuitry is configured to attempt cell selection of a cell and obtain barring information associated with the cell upon the cell being barred. The control unit is configured to initial selection of the cell and to determine a varied barring time at least partially based on the barring information and system characteristics upon the cell being barred.
Abstract:
Embodiments described herein relate generally to a communication between a user equipment (UE) and an evolved Node B (eNB) that are both running in Enhanced Coverage (EC) mode. The UE and eNB may communicate in a contention-based random access procedure having an EC level that may be used to determine the number of times an RA preamble may be sent, and one or more RA response opportunity windows that may be used to receive one or more RA responses. Other embodiments may be described and/or claimed.
Abstract:
Embodiments of the present disclosure describe systems, devices, and methods for interworking between a universal mobile telecommunications system (UMTS) network and a wireless local area network (WLAN). Various embodiments may include utilizing traffic steering rules based on radio access network assistance parameters to perform traffic steering between the UMTS network and the WLAN. Other embodiments may be described or claimed.
Abstract:
User Equipment (UE) may skip the Access Class Barring (ACB) procedure for specific services, such as MMTEL voice, MMTEL video, and SMS. In one implementation, NAS layer of a UE may: receive, from an upper layer relative to the NAS layer, a request for a particular service type that is being originated by the UE; receive an indication, from a Radio Resource Control (RRC) layer of the UE, that access to a cell, associated with the UE, is barred; and bypass the indication that access to the cell is barred, when the particular service type matches a predetermined set of service types. The bypassing may include: requesting that the RRC layer establish an RRC connection for the service request, and notifying the RRC layer that the request for the RRC connection corresponds to the particular service type.
