摘要： Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.

摘要： Multiple input multiple output (MIMO) communication systems and methods for chip to chip and intrachip communication are disclosed. In one aspect, MIMO techniques that have been applied to wireless communication systems are applied to interchip and intrachip communication systems. In particular, a transfer function is applied at the transmitter, and a reverse transfer function is applied at the receiver. The transfer function dynamically changes based on channel conditions to cancel or otherwise mitigate electromagnetic interference (EMI) and crosstalk conditions. In an exemplary aspect, a sum of power levels across the channels may have a maximum. To abide by such power level constraint, the transfer function may be optimized to reduce interference while remaining within the power level constraint.

摘要： A method, an apparatus, and a computer program product are provided. The apparatus may be configured to link user equipment contexts associated with same physical device. A network entity may determine a link between a first context and a second context of a user equipment, and may combine procedures related to the first and the second contexts when the first context and the second context are linked. The first context and the second context may be associated with a common international mobile equipment identity of the UE and different international mobile subscriber identities. A wireless device may maintain a first wireless communications link corresponding to a first subscription and a second wireless communications link corresponding to a second subscription. The wireless device may refrain from performing a first radio resource procedure in relation to the first subscription after performing a similar radio resource procedure in relation to the second subscription.

A wireless device may apply phase precompensation to multiple user-multiple input multiple output (MU-MIMO) communications with different wireless devices. The wireless device may measure one or more axis offsets between antenna arrays of the wireless device and other antenna arrays of different wireless devices. The wireless device may perform MU-MIMO communications with the different wireless devices by applying phase precompensation according to the axis offset. For example, the wireless device may transmit or receive communications from multiple wireless devices using the phase precompensation.

摘要： Methods, systems, and devices for wireless communications are described. A base station may determine to enable orbital angular momentum (OAM) beamforming for communications with a user equipment (UE), for example, based on one or more communications parameters and receiving a message from the UE indicating a capability of the UE to use OAM beamforming. The base station may transmit control signaling to the UE indicating that OAM beamforming is enabled. In some examples, the base station may transmit control signaling indicating an OAM configuration, which may be for a same slot in which the control signaling is transmitted or a subsequent slot. The base station may transmit a downlink transmission to the UE via OAM beamforming. In some examples, the base station may estimate and correct misalignment associated with OAM beamforming. In some examples, the base station may disable OAM beamforming and transmit an indication that OAM beamforming is disabled.

摘要： Methods, systems, and devices for wireless communications are described. A first wireless device may receive a request for beamforming information associated with line-of-sight (LoS) multiple input multiple output (MIMO) communication from a second wireless device. The first wireless device may generate a channel estimation matrix for a channel between rectangular antenna arrays of the respective wireless devices, the channel estimation matrix including one or more quadratic terms for the LoS MIMO communication. The first wireless device may generate a first sub-matrix and a second sub-matrix based on the channel estimation matrix. The first wireless device may transmit an indication of a set of precoders for the LoS MIMO communication, the set of precoders based on a symmetry associated with the first and second sub-matrices, and may receive the LoS MIMO communication from the second wireless device based on the set of precoders.

摘要： Methods, systems, and devices for wireless communications are described. A device may be configured to include an array of lenses along with multiple antenna arrays that each include a set of antenna elements. The antenna arrays may each support multiple beam directions, such as a respective beam direction for each lens of the array of lenses. If beams for multiple antenna arrays concurrently pass through the same lens, the lens may contribute to maintaining separation between the beams. Lenses may also contribute to the shaping of beams, and the use of multiple lenses may enhance a coverage area for beams transmitted or received by the antenna arrays.
