    Abstract: Methods, systems, and devices for wireless communications are described. A first device may transmit, from a first antenna of a first antenna array of the first device to a second antenna of a second antenna array of a second device, a first set of reference signals. The first device may transmit, from a first plurality of antennas of the first antenna array to a second plurality of antennas of the second antenna array, a second plurality of reference signals. The first device may receive, from the second device, an indication based at least in part on a linear offset and one or more rotational offsets estimated by the second device associated with the first set of reference signals and the second plurality of reference signals. The first device may communicate with the second device using the first antenna array based on the indication.

    Abstract: Methods, systems, and devices for wireless communications are described. Communication devices may perform secret key generation using a set of line-of-sight (LOS) communication modes to secure a physical channel. For example, a first device and a second device may communicate a set of reference signals over the physical channel using a set of LOS communication modes. The first device and the second device may generate a secret key based on the set of LOS communication modes, for example, by using information associated with the set of LOS communication modes to compute the secret key using a key derivation function that outputs the secret key. The first device and the second device may secure the physical channel by encrypting signaling between the first device and the second device with the secret key and communicating the signaling over the physical channel using LOS communications.

    Abstract: A mobile wireless device may dynamically alter a downlink MIMO function by switching it on and off, or switching between different downlink MIMO configurations, such as 2×MIMO and 4×MIMO. Still further, a mobile device having greater than two antennas may dynamically select a subset of the antennas to be used to receive a MIMO transmission, and further, enable a mobile device to request a subset of antennas at a base station to be used for the MIMO transmission. This dynamic control of the MIMO mode or configuration may be achieved by using implicit signaling, by way of an enlarged code word set in CQI feedback transmissions, or by using explicit signaling, by way of E-DPCCH orders. In this way, a MIMO-capable mobile device may dynamically be configured for downlink MIMO transmissions as the conditions demand, enabling MIMO to be switched off when its use might otherwise cause performance to suffer.

    Abstract translation: 移动无线设备可以通过接通和关断或者在诸如2×MIMO和4×MIMO的不同下行链路MIMO配置之间切换来动态地改变下行链路MIMO功能。 另外，具有大于两个天线的移动设备可以动态地选择要用于接收MIMO传输的天线的子集，并且还使移动设备能够请求在基站处的天线子集用于 MIMO传输。 MIMO模式或配置的这种动态控制可以通过使用隐式信令，通过在CQI反馈传输中设置的扩大码字，或者通过使用显式信令，通过E-DPCCH命令来实现。 以这种方式，具有MIMO能力的移动设备可以根据条件需要被动态地配置用于下行链路MIMO传输，使得在其使用可能导致性能受损的情况下使MIMO能够被关闭。

    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may include a first set of antenna arrays disposed in a first shape and a receiving device may include a second set of antenna arrays disposed in a second shape. A first axis that intersects an antenna array of the first set of antenna arrays and a centroid of the first shape may be offset from a vertical direction by a first angular offset. A second axis that intersects an antenna array of the second set of antenna arrays and a centroid of the second shape may be offset from the vertical direction by a second angular offset that is different than the first angular offset. The transmitting device may transmit signaling to the receiving device using the first and second sets of antenna arrays, respectively based on difference between the first and second angular offsets.

    Abstract: Methods, systems, and devices for wireless communications are described. A first device may select, from multiple orbital angular momentum (OAM) modes, a set of one or more primary OAM modes and a set of one or more secondary OAM modes, where at least one primary OAM mode is activated periodically and at least one secondary OAM mode is activated based on a trigger. The first device may transmit, to a second device, a message indicating a configuration for the selected set of one or more primary OAM modes, the selected set of one or more secondary OAM modes, and discontinuous reception (DRX) parameters for each of the sets of OAM modes. The second device may monitor for a signal using a primary OAM mode using the DRX parameters for the set of primary OAM modes, and the second device may activate a second OAM mode based on receiving the signal.
