Abstract: Techniques for deriving a WLAN security context from an existing WWAN security context are provided. According to certain aspects, a user equipment (UE) establishes a secure connection with a wireless wide area network (WWAN). The UE may receive from the WWAN an indication of a wireless local area network (WLAN) for which to derive a security context. The UE then derives the security context for the WLAN, based on a security context for the WWAN obtained while establishing the secure connection with the WWAN and establishes a secure connection with the WLAN using the derived security context for the WLAN. This permits the UE to establish a Robust Security Network Association (RSNA) with the WLAN while avoiding lengthy authentication procedures with an AAA server, thus speeding up the association process.

Abstract: Interactions between radio access network (RAN) -based and legacy wireless local area network (WLAN) mobility is described in which a multi-mode mobile device receives a management indication from a wide area wireless network (WW AN) to manage connectivity with the WLAN, such as in discovery, association, or specific traffic offload for the WLAN. The mobile device obtains a status of its internal WLAN radio and determines whether to process the management indication based on the status. Data offloading is also described in which the mobile device receives an indication from the WW AN to offload data to the WLAN associated with the mobile device. In response, the mobile device suspends application of a current offload policy, which had been received from the core network, based on the indication and transmits its data according to the indication.

Abstract: Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station

Abstract: A scheduled data communication system of an access node and terminal supports recurring communications of small data amounts such as Voice over IP (VoIP). In order to make error checking more robust in a random access response (RAR), such as for semi-persistent scheduling (SPS) for VoIP, a portion of a grant or assignment payload has a constraint imposed that can be verified as a condition precedent to determining a valid grant or assignment rather than only relying upon a validity check field, such as a cyclic redundancy check (CRC). Thereby, incorrect validation of a grant or assignment is avoided for dynamic scheduling or for semi-persistent scheduling, the latter causing a persistent error.

Abstract translation: 接入节点和终端的调度数据通信系统支持诸如IP语音（VoIP）等小数据量的循环通信。 为了使随机接入响应（RAR）中的错误检查（例如用于VoIP的半静态调度（SPS））更加鲁棒，授权或分配有效载荷的一部分具有强制的约束，可以被验证为先决条件 以确定有效的授权或分配，而不仅仅依赖于诸如循环冗余校验（CRC）的有效性检查字段。 因此，动态调度或半永久调度避免了授权或分配的不正确验证，后者导致持续性错误。

Abstract: Techniques for sending a message for random access by a user equipment (UE) are described. In an aspect, the UE may send the message on a control channel for random access and may send a reserved channel identifier to indicate the message being sent on the control channel. In another aspect, the UE may send the message in a protocol data unit (PDU) and may send additional information (e.g., a buffer status report) in the PDU if it can accommodate the additional information. In yet another aspect, the UE may generate a short message authentication code for integrity protection (MAC-I) for the message. The short MAC-I may have a smaller size and may be used to authenticate the UE. In yet another aspect, the UE may send a UE ID of one of multiple types for random access and may convey the UE ID type via a format field in the message.

Abstract: Techniques for supporting random access by user equipments (UEs) in a wireless communication system are described. In one design, a UE transmits a random access (RA) preamble for random access. The UE thereafter receives a random access response composed of a first part and a second part. The first part includes a list of N RA preamble IDs for N RA preambles being responded to by the random access response, where N ≥ 1. The second part includes N individual RA responses for the N RA preambles being responded to. The UE processes the first part to detect for an RA preamble ID of the RA preamble transmitted by the UE. If this RA preamble ID is not detected, then the UE skips the second part. Otherwise, the UE processes the second part to obtain an individual RA response for the transmitted RA preamble.

Abstract translation: 描述了用于支持无线通信系统中的用户设备（UE）的随机接入的技术。 在一种设计中，UE发送用于随机接入的随机接入（RA）前导码。 UE然后接收由第一部分和第二部分组成的随机接入响应。 第一部分包括由随机接入响应响应的N个RA前导码的N个RA前同步码的列表，其中N = 1。第二部分包括对N个RA前导码进行响应的N个个体RA响应。 UE处理第一部分以检测由UE发送的RA前导码的RA前导码ID。 如果没有检测到RA前导码ID，则UE跳过第二部分。 否则，UE处理第二部分以获得用于所发送的RA前导码的单独的RA响应。
