Abstract:
A user equipment (UE) may determine when to monitor for downlink (DL) communications such as paging messages based on both a received extended idle discontinuous reception (eI-DRX) cycle and a change in a downlink channel reliability condition of the UE. A base station may also adjust its transmission of paging information to a UE based on a eI-DRX cycle.
Abstract:
Techniques are provided for decoupling uplink and downlink operations. According to certain aspects, a wireless node (e.g., a low power node) may receive, from a base station of a first cell, signaling indicating a random access channel (RACH) configuration for a wireless device. The wireless node may then detect the wireless node performing a RACH detection (based on the RACH configuration) and report the RACH detection and desired UL configuration to the base station of the first cell. The base station of the first cell may then select the wireless node for serving the wireless device for UL operations (e.g., based on the reported RACH detection-and similar reports from other wireless nodes detecting the same RACH procedure).
Abstract:
Methods, systems, and devices are described for facilitating Machine Type Communication in a wireless communications system. Link budget-limited MTC devices, may be supported. An MTC physical broadcast channel may be utilized for the Machine Type Communication. The MTC physical broadcast channel may be transmitted over one or more subframes different from a regular physical broadcast channel. The payload for the MTC physical broadcast channel may be reduced. The MTC physical broadcast channel may also be utilized to indicate the presence of paging and/or to indicate a change in system information. Some embodiments utilize one or more MTC-specific system information blocks. The MTC-specific system information blocks may combine and/or simplify multiple system information blocks. The location of the MTC system information blocks may be predetermined or information about their location may be transmitted over the MTC physical broadcast channel. An enhanced paging channel may be used to indicate system information updates.
Abstract:
A method, an apparatus, and a computer program product for wireless communication in which provisioning of credentials for network deployments are provided. As such, the method, apparatus, and computer program product may provision a user equipment (UE) even though the UE does not have any valid security credentials, so as to provide access to a network (e.g., a network using a contention based frequency band such as a Long Term Evolution (LTE) Advanced network in the contention based radio frequency band). Accordingly, in some aspects, the present method, apparatus, and computer program product may enable the UE to perform a provisioning procedure with one or more network entities to obtain one or more security credential parameters.
Abstract:
Extended DRX (e-DRX) operation using hyper frame extension signaling are described. The hyper frame extension signaling may extend the system frame number (SFN) range while maintaining backward compatibility for legacy devices not configured to use the extended SFN range. The hyper-SFN extension signaling may include an index to a hyper-SFN transmitted as part of system information different than that used for transmission of the SFN. UEs configured to use the hyper-SFN may effectively use a longer or extended SFN range that includes the legacy SFN range and the hyper-SFN range. The hyper-SFN extension may be used in an extended idle DRX (eI-DRX) mode which may coexist with existing I-DRX mode on the same paging resources. Additionally or alternatively, paging may be differentiated for eI-DRX mode UEs using separate paging occasions or a new paging radio network temporary identifier (RNTI).
Abstract:
Techniques are described for configuring wireless service for a user equipment (UE) in a wireless communications network in which the UE may be served over one or more of multiple available cells. Wireless service for the UE may be configured based on parameters associated with each of the multiple cells, such as, for example, a primary/secondary cell designation of a cell, whether the cell operates using a licensed or an unlicensed radio frequency spectrum band, a radio access technology associated with a cell, and/or an operating frequency band of a cell. Based on the parameters for each cell, one or more cell configurations for serving the UE may be provided. The cell configurations may identify, for example, a set of rules that control how much and/or what type of traffic is sent on different cells.
Abstract:
An operational characteristic of a relay is determined. The relay is a user equipment (UE) serving as an eNB. The operational characteristic includes one or more of a quality of a relay backhaul and a capacity of the relay backhaul. The relay backhaul includes a communications link between the relay and an eNB. A determination of whether to perform a handover of a UE is made based on the operational characteristic of the relay and a corresponding operational characteristic of the eNB.
Abstract:
Systems, methods, and devices for priority based management of the connections between a device and a network are described herein. In some aspects, a device may include multiple applications with different access priorities. As a result of a mobility event, such as change in location or resuming operation after an idle period, the device may be configured to transmit a signal indicating its status. The signal may include an access priority value. Various methods and systems for determining an access priority value for devices configured to support one or more access priorities are described.
Abstract:
The state of an access link and backhaul link of a low power node may be determined and controlled after a low power node is initialized. The overhead signaling on the access link of a relay is controlled based on detecting a user equipment (UE). The connection on the backhaul link of the relay is managed in response to the overhead signaling on the access link.
Abstract:
Methods, systems, and devices for wireless communications are described. In a service-based network, groups of core network services may share a user equipment (UE) credential or network subscription. Signaling between a UE and a service-based network (e.g., via a distributed unit) enables the UE to establish a service context for communications with multiple core network services in a same service group. A UE may receive control signaling from the network indicating service groups offered by the service-based network. The control signaling may indicate the services included in each service group and how to access the service group. The UE may transmit an access request indicating a selected service group to the network, and in response, the network may indicate a service context for communicating with the services included in the service group. The UE may use the same service context to access the different services in the service group.
