    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may divide a data stream into multiple data sub-streams. The wireless device may map the data sub-streams to a set of layers of a multi-layer modulated stream. The wireless device may encode, rate match, modulate, spread and scramble the set of layers before combining them into a combined data stream. The number of layers in the set of layers may be configurable. The wireless device may apply scrambling sequences to the layers. An additional phase rotation or power scaling factor may be applied to each layer. The layers may then be synchronized and combined into a combined data stream. A set of combined data streams may be mapped to multiple-input, multiple-output (MIMO) layers. The wireless device may precode the MIMO layers, map the MIMO layers to tones, and transmit the combined data streams.

    Abstract: A method for network selection in a cellular and WLAN interworked network may include determining, by a UE, an association state between the UE and a WLAN access point. The UE may select a metric of the access point, based at least in part on the determined association state. The UE may determine a value of the metric. The UE may determine whether to report the value of the metric to a base station of the cellular wireless network, based on various factors. These factors may include the association state, the value of the at least one metric relative to a threshold value, a change in the association state, or receiving a reporting instruction from the base station. The UE may report the value of the metric to a base station, based on its determination. A base station may perform operations complementary to the UE, for network selection.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for modified power management for UEs in a wireless communication system that utilizes one or more RANs for communication. For example, certain aspects of the present disclosure relate to a technique for controlling when the UE is placed in a low power state in the first RAN based, at least in part, on inactivity of the UE in the first RAN. Certain aspects of the present disclosure also relate to controlling when to modify one or more network bearers between the first RAN or the second RAN and the core network based, at least in part, on at least one of inactivity on the one or more network bearers or inactivity in both the first RAN and the second RAN. According to certain aspects, the first RAN may include a WWAN and the second RAN may include a WLAN.

    Abstract: Methods, systems, and devices are described for routing modification based on handover detection in UEs and network equipment. According to the principles of the present specification, communication between a User Equipment (UE) and a network equipment may be established over a first radio access technology (RAT) and a second RAT, and a coupling between the first RAT and the second RAT may be identified in the communication between the UE and the network equipment. A handover event associated with at least one of the RATs may be identified, and network traffic routing may be adapted based at least in part on the identified handover event and the coupling between the first RAT and the second RAT.
