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.

The connection on the backhaul link of the relay is managed in response to the overhead signaling on the access link.

Abstract: Various techniques and approaches described herein may be applied to control congestion at a session management (SM) function (SMF) based on at least one back-off timer maintained at a user equipment (UE). In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE may be configured to establish a protocol data unit (PDU) session with a SMF. The UE may be configured to determine whether a back-off timer associated with the PDU session is terminated. The UE may refrain from sending, to the SMF, data over a control plane associated with the PDU session when the back-off timer is unterminated. The UE may send, to the SMF, the data over the control plane associated with the PDU session when the back-off timer is terminated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to establish a multicast session. The request may identify a multicast service session including a multicast quality of service flow. The UE may receive, from a base station wirelessly communicating with the UE, an indication of communication resources for the UE to use to receive multicast packets of the multicast service session from a content provider via a tunnel between a first network node and the base station. The tunnel may be established for the multicast service session based on identifying that the multicast service session lacks an existing tunnel between the first network node and the base station. The UE may identify a discontinuous reception (DRX) cycle for the multicast service session, and receive the multicast packets from the base station according to the indicated communication resources and the identified DRX cycle.
