摘要： Methods and Devices that provide mechanisms for an air interface capability exchange are disclosed. The air interface capability exchange enables a user equipment device to signal its air interface configuration capabilities to a network device to facilitate software configurable air interface (SoftAI) optimization. The air interface capability exchange involves a UE device signaling information regarding an air interface configuration capability type of the device's air interface. The air interface configuration capability type identifies whether the device supports multiple air interface configurations of the air interface. The UE device may also transmit information regarding air interface configuration options that it supports. The network device may determine a configuration for the UE device's air interface based at least in part on the information provided by the UE device.

摘要： Methods and devices for performing role change are described. Dynamic signaling is used. Example formats for uplink and downlink signaling is also described. In some examples, an electronic device (ED) receives, via dynamic signaling, from a first serving cell, with which the ED initially has a primary connection, a role change trigger. The role change trigger causes the ED to use a connection with a second serving cell, with which the ED initially has a secondary connection, as the primary connection instead of the first serving cell.

摘要： Methods and apparatus are described for enabling downlink transparent relay in a wireless communication network. In a wireless communications network, a base station and a mobile station may communicate with each other via a relay station, as needed. Transparent relay may allow for relay communication between a base station and a mobile station although the mobile station is unaware of the relay station. However, non-contiguous transmission of a relay station may lead to channel quality measurement and channel estimation degradation during downlink transparent relay. According to some aspects, a base station may schedule a mobile station to a transmission mode that utilizes dedicated pilot signals for downlink transparent relay, and a relay station may transmit data and dedicated pilot signals over the same channel resources as the base station. According to some aspects, the relay station may null common pilot signals transmitted by the base station.
摘要翻译：描述了用于在无线通信网络中启用下行链路透明中继的方法和装置。在无线通信网络中，基站和移动台可以根据需要经由中继站进行通信。尽管移动台不知道中继站，但是透明中继可以允许基站和移动台之间的中继通信。然而，中继站的不连续传输可能导致下行链路透明中继期间的信道质量测量和信道估计恶化。根据一些方面，基站可以将移动台调度为利用用于下行链路透明中继的专用导频信号的传输模式，并且中继站可以通过与基站相同的信道资源发送数据和专用导频信号。根据一些方面，中继站可以丢弃由基站发送的公共导频信号。
