摘要： A method is provided for confirming whether a data unit transmitted from a base station (BS) was successfully relayed to a subscriber station via one of a plurality of relay stations in a multihop cooperative relay network. Selected ones of the relay stations are designated as: a front-linked relay station designed to only transmit a negative acknowledgement message to the BS upon receiving a data unit from the BS that is unable to be decoded and not to transmit an acknowledgement message upon receiving a data unit from the BS that is able to be decoded, and a back-linked relay station designed to only transmit a acknowledgement message to the BS upon receiving the data unit from the BS that is able to be decoded and not to transmit a negative acknowledgement message to the BS upon receiving a data unit from the BS that is unable to be decoded.

摘要： Circuit-switched fallback (CSFB) is a technique to deliver voice-services to a mobile, when the mobile is camped in a long-term evolution (LTE) network. This may be required when the LTE network does not support voice services natively. If a user makes a mobile originating (MO) call, or receives a mobile terminating (MT) call, the UE may inform the LTE network that the UE is leaving for the call by initiating a call setup procedure. However, there may be instances where the call setup procedure may fail. If the call setup procedure was either not initiated, or was initiated but failed, the UE may determine to search for a suitable CS RAT/cell on its own without instructions/commands from the network. Therefore, certain aspects of the present disclosure provide techniques for the UE to find CS services based on information collected at the UE.
摘要翻译： 当移动台驻扎在长期演进（LTE）网络中时，电路交换回退（CSFB）是一种向移动设备提供语音服务的技术。 当LTE网络本身不支持语音服务时，可能需要这样做。 如果用户进行移动发起（MO）呼叫或接收移动终止（MT）呼叫，则UE可以通过发起呼叫建立过程来通知LTE网络UE正在进行呼叫。 但是，可能存在呼叫建立过程可能失败的情况。 如果呼叫建立过程未被发起或被发起但失败，则UE可以确定自己搜索合适的CS RAT /小区而没有来自网络的指令/命令。 因此，本公开的某些方面提供了用于UE基于在UE处收集的信息来找到CS服务的技术。

摘要： Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.
摘要翻译： 本公开的某些方面提出了用于以不同的双工模式独立地发送由用户设备（UE）支持的特征的技术的技术。 UE可以能够以频分双工（FDD）和时分双工（TDD）模式进行通信。 UE可以获得FDD专用特征组指示符（FGI）集合和设置了TDD特定的FGI，并且设置FDD特定FGI集合或TDD特定FGI中的至少一个集合。 此外，UE可以采取一种或多种动作来减少转换到与其当前操作模式不同的操作模式的可能性。

摘要： Certain aspects of the disclosure relate generally to search of radio access technologies (RAT). For example, certain aspects of the present disclosure relate to a technique for performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RATs, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, a user equipment (UE) may be configured to periodically search for higher priority RATs in neighboring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further configured to evaluate, or “pre-evaluate”, criteria for cell reselection from found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.

摘要： A method is provided for facilitating preservation of session context information during an inter-radio access technology service retry. A user equipment (UE) may initiate a data transmission for a first service over a wireless communication session with a first network. Upon ascertaining that the first service has failed over the first network, a failover procedure is initiated by sending a service request for a second service to the first network. The second service may be distinct from the first service and has the effect of suspending the wireless communication session with the first network. The UE then resends the data transmission for the first service over a second network. The UE then resumes use of the wireless communication session over the first network after resending the data transmission over the second network. This resumption is done by using context information for the wireless communication session preserved prior to the suspension.
摘要翻译： 提供了一种在无线电接入技术服务重试期间便于保持会话上下文信息的方法。 用户设备（UE）可以通过与第一网络的无线通信会话来发起第一服务的数据传输。 在确定第一服务在第一网络上发生故障之后，通过向第一网络发送用于第二服务的服务请求来启动故障切换过程。 第二服务可以不同于第一服务，并且具有暂停与第一网络的无线通信会话的效果。 然后，UE通过第二网络重新发送用于第一服务的数据传输。 然后，在重新发送通过第二网络的数据传输之后，UE在第一网络上恢复使用无线通信会话。 该恢复通过使用在暂停之前保存的无线通信会话的上下文信息来完成。

摘要： A CS fallback procedure handles conflict that may arise when handover operations occur during CS fallback. If CS fallback is initiated for an access terminal and handover of that access terminal is then initiated before the CS fallback completes, the target for the handover is informed of the CS fallback so that the target may perform the appropriate CS fallback operations.

摘要： Multi-mode system selection (MMSS) enables a mobile station (MS) to prioritize MS preference for selecting particular radio air-interfaces (AI) across multiple standards (e.g., 3GPP, 3GPP2, WiMAX). 3GPP2 is developing a scheme MMSS-3GPP2 which is usually referred to as simply ‘MMSS.’ Other schemes exist e.g., proprietary ones (e.g., internal ePRL), an MMSS-3GPP based on the PLMN with Access Technologies of non-3GPP systems. MMSS OTASP messages and parameters are being defined in 3GPP2 to allow the carriers to provision MMSS parameters to the mobile device. With MMSS, the mobile can select and hence acquire cdma2000 and non-cdma2000 systems (e.g., LTE, WiMAX) based on carrier's preferences.
摘要翻译： 多模式系统选择（MMSS）使得移动站（MS）能够优先考虑MS偏好以跨越多个标准（例如，3GPP，3GPP2，WiMAX）选择特定无线电空中接口（AI）。 3GPP2正在开发通常简称为“MMSS”的MMSS-3GPP2方案。其他方案存在，例如专有的方案（例如，内部ePRL），基于具有非3GPP系统的接入技术的PLMN的MMSS-3GPP。 在3GPP2中定义MMSS OTASP消息和参数，以允许运营商向移动设备提供MMSS参数。 使用MMSS，移动台可以基于载波的偏好来选择并因此获取cdma2000和非cdma2000系统（例如，LTE，WiMAX）。
