Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station. In some aspects, the mobile device may scramble the information associated with signals and transmit the information associated with signals to the base station prior to establishing a security context for a connection between the mobile device and the base station.

Abstract: Systems, methods, and devices of the various embodiments provide for header extension preservation, security, authentication, and/or protocol translation for Multipath Real-Time Transport Protocol (MPRTP). Various embodiments include methods that may be implemented in a processor of a computing device for MPRTP transmission of Real-Time Transport Protocol (RTP) packets. Various embodiments may include receiving an RTP packet in which the received RTP packet may be part of an RTP stream that may be protected using secure RTP (SRTP), and applying an authentication signature to the RTP packet to authenticate an MPRTP header extension separate from a body of the RTP packet. Various embodiments may include sending and/or receiving MPRTP subflows of an MPRTP session in which a same security context may be applied across all MPRTP subflows of the MPRTP session.

Abstract: Techniques for sending packets and maintaining synchronization during handover is described. A user equipment (UE) may be handed over from a source base station to a target base station. The source base station may forward packets for the UE to the target base station, which may receive the packets out of order. In one design, the target base station may determine whether each packet can be sent in order to the UE, send the packet if it can be sent in order, and discard the packet otherwise. In another design, the target base station may re-order packets received within a re-ordering window and may send the re-ordered packets to the UE. In yet another design, the target base station may process each packet received out of order as if the packet is in order, e.g., by incrementing a hyper-frame number (HFN) or re-assigning the packet with a later sequence number.

Abstract: Methods and apparatuses for serving cell management of a user equipment (UE) are presented. Particularly, methods and apparatuses are presented for suppressing a serving cell change based on a speed of the UE. For instance, an example method is presented for serving cell management that may include determining that a serving cell change condition exists for an initiation of a serving cell change for the UE, wherein the serving cell change comprises changing a serving cell of the UE from a macro cell to a low power cell. In addition, the example method may include obtaining a speed of the UE and suppressing the initiation of the serving cell change based on the speed of the UE.

Abstract: Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.

Abstract: Methods, apparatus, and computer-readable media for wireless communication may involve techniques for throughput estimation. An expected air time parameter may be used as a parameter for estimating throughput. The expected air time parameter may be indicative of an estimated air time fraction obtainable for communications using an access point (AP), for example, between a wireless station (STA) and the AP. Either the expected air time parameter or an estimated air time fraction determined (e.g., calculated) from the expected air time parameter may be transmitted from the AP to the STA (or other communication device) to allow the STA (or other communication device) to determine an estimated throughput for communications using the AP.

Abstract: Techniques for prioritizing user equipments (UEs) for switching between wireless systems are disclosed. The wireless systems may be part of a small cell and may include a WLAN system and a cellular system. In one design, a network entity (e.g., the small cell) may identify a plurality of UEs communicating with a first wireless system. The first wireless system may be one of a plurality of wireless systems providing communication coverage for the UEs. The network entity may determine priorities of the UEs for switching from the first wireless system to a second wireless system. The network entity may then select at least one UE among the plurality of UEs to switch from the first wireless system to the second wireless system based on the priorities of the UEs.

Abstract: Techniques for switching a user equipment (UE) between wireless systems by first establishing a connection with a target system before disconnecting from a serving system are disclosed. In one design, the UE may initially communicate with a first wireless system (e.g., a WLAN system) of a first radio technology. The UE may receive a page to establish a connection with a second wireless system (e.g., a cellular system) of a second radio technology. The first and second wireless systems may be part of a small cell. The page may be sent by the second wireless system to the UE in response to a decision by a network entity to switch the UE from the first wireless system to the second wireless system. The UE may establish a connection with the second wireless system in response to the page and may thereafter terminate communication with the first wireless system.
