摘要： A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different polarization directions. The plurality of antennas includes a first antenna and second antenna which are operated in a coordinated fashion. During reception a signal received via the first antenna is subjected to a phase shift operation before being combined with a signal received via the second antenna. During transmission a signal to be communicated is subjected to a phase shift operation and the phase shifted signal is transmitted over the first antenna while the non-phase shifted signal is transmitted over the second antenna. The amount of phase shift is a function of the difference in polarization directions between the first and second antennas. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally positioning one or more electrical antennas.

摘要： Methods and apparatus which support the use of differently polarized antennas to schedule two or more users employing multiple antennas with different polarization, on the same communications segment, e.g. a time/frequency slab, in either the uplink or downlink are described. Various embodiments include an access node which classifies and schedules wireless terminals to segments as a function of suitability for single polarization direction communications. Some embodiments are directed to methods and apparatus for operating a communications device supporting the use of multiple antennas having different polarization, to implement a polarization based multiple access scheme. Unlike Spatial Division multiple access schemes, the users sharing a communications segment in the polarization based scheme need not be geographically well separated. Another advantage of using the proposed method is that the communications system does not necessarily have to use a complex minimum mean square error receiver or implement successive iteration cancellation techniques, thereby reducing cost and system complexity.
摘要翻译：支持使用不同极化天线来调度在相同通信段上采用具有不同极化的多个天线的两个或更多个用户的方法和装置，例如，描述在上行链路或下行链路中的时间/频率块。各种实施例包括将无线终端分类并将其调度为对于单极化方向通信的适用性的函数的接入节点。一些实施例涉及用于操作支持使用具有不同极化的多个天线的通信设备的方法和装置，以实现基于偏振的多址方案。与空间分多址方案不同，在基于偏振的方案中共享通信段的用户不需要在地理上很好地分离。使用所提出的方法的另一个优点是通信系统不一定必须使用复数最小均方误差接收器或实现连续的迭代消除技术，从而降低成本和系统复杂度。

摘要： A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different associated polarization directions. The plurality of antennas includes an electrical antenna, e.g., a dipole antenna, and a magnetic antenna, e.g., a loop antenna or a slot antenna. In one embodiment the electrical antenna is used for receiving and/or transmitting signals associated with a vertical polarization direction, while the magnetic antenna is used for receiving and/or transmitting signals associated with a horizontal polarization direction. In some embodiments different data streams are communicated concurrently via the electrical and magnetic antennas. Methods for operating the communications device to switch between the electrical and magnetic antennas and/or to control reception and/or transmission are described. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally azimuth positioning the magnetic antenna.

摘要： A wireless communications device, e.g., a mobile node supporting direct peer to peer communications, performs a self-calibration of one or more of: receiver IQ imbalance, transmitter IQ imbalance, receiver DC offset, and transmitter DC offset. The wireless communications device, operating in calibration mode, intentionally sets the oscillator frequency used for downconversion in its receiver module to a different frequency than the oscillator frequency used for upconversion in its transmitter module. A first baseband signal, e.g., a single tone test signal, is input to the transmitter module and an upconverted transmit signal is generated. The transmit signal is routed via a feedback loop to the receiver, which performs a downconversion operation. Power and/or phase measurements of the signals output from the downcoversion are used to determine IQ imbalance compensation information and DC offset compensation information. The determined compensation information is used subsequently when operating in a communications mode of operation.

摘要： Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e.g., relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

摘要： Methods, systems, and devices for wireless communications are described. A transmitted may use a closed loop precoder for line-of-sight (LOS) multiple-input multiple-output (MIMO) communications that uses information such as distance feedback or LOS MIMO channel state feedback. A closed loop precoder may be associated with less overhead than a precoder based on full channel knowledge, such as an SVD precoder. A receiver may estimate a channel based on channel state information reference signals transmitted by the transmitter and calculate a spectral efficiency for one or more precoders of a set of precoders associated with the channel for a LOS MIMO mode. The receiver may send feedback to the transmitter that indicates a selected precoder of the set of LOS MIMO precoders based on the calculated spectral efficiencies. The transmitter may precode messages using the reported closed loop precoder.

摘要： Methods, systems, and devices for wireless communications are described. A transmitter may select a precoder from a codebook for precoding one or more signals for transmission to a receiver. The transmitter may select the precoder from the codebook based on antenna configurations at the transmitter and the receiver. The precoder may be constructed using one or more Slepian sequences. In some implementations, the Slepian sequences may be associated with a quantity of transmit antennas at the transmitter. For instance, a length of each Slepian sequence may correspond to (for example, be equal to) a quantity of transmit antennas at the transmitter. Further, the Slepian sequences may be associated with a bandwidth within which to concentrate the one or more signals. Once the transmitter selects the precoder, the transmitter may precode the one or more signals and transmit the precoded signals to the receiver.

摘要： Methods, systems, and devices for wireless communications are described. For example, a first wireless device may transmit, via a first beam, a first set of data and a first reference signal associated with the data on a data channel for beam refinement. The first wireless device may further transmit, via a second beam, a second set of data and a second reference signal on the data channel for beam refinement. A second device may receive the first set of data and first reference signal in addition to receiving the second set of data and second reference signal. The second device may transmit, to the first device, beam refinement feedback information for the first beam and the second beam based on receiving the first reference signal and the second reference signal on the data channel. Thus, the first device may refine beams based on a data transmission over a data channel.

摘要： Methods, systems, and devices for wireless communications are described for implementation of higher rank transmissions (e.g., higher rank line of sight (LOS) schemes) over a given beam direction associated with a selected transmission configuration indicator (TCI) state. According to some aspects, expanded antenna arrays, spatial separation (e.g., distance) between antenna elements, lower carrier frequencies (e.g., associated with frequency range 4 (FR4) systems), etc. may be leveraged to communicate uncorrelated signals (e.g., independent streams across spatial layers) for higher rank transmissions using a given TCI state (e.g., using a single beam direction). Various aspects of the described techniques may provide for higher rank directional communications by a user equipment (UE) (e.g., via uncorrelation in a single UE), higher rank directional communications by select UEs (e.g., via uncorrelation across specific UEs), base station antenna selection for uncorrelation at multiple served UEs, etc.
