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 codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a repeater may receive a first signal from a transmitting device and determine an amplified version of the signal may not be successfully received by a receiving device. The repeater may transmit a mode switch message to the transmitting device to indicate a request for the transmitting device to switch to a transmission mode associated with one or more different transmission parameters based on detecting that the amplified version of the signal may not be received by the receiving device. The transmitting device may adjust one or more transmission parameters according to the mode switch message and may transmit a second signal to the repeater based on the adjusted transmission parameters. The repeater, operating according to the mode switch message, may receive the second signal and transmit an amplified version of the second signal to the receiving device.

Abstract: A base station may identify one or more beams toward a node for communication with at least one UE. The one or more beams may correspond to a plurality of beams from the node. The base station may transmit, to the node, an indication to adjust a surface phase of the node corresponding to the one or more beams or one of the plurality of beams from the node. The base station may select at least one beam of the plurality of beams from the node for communication with the at least one UE. The base station may communicate with the at least one UE via the node and the at least one beam. The at least one beam of the plurality of beams from the node may be based on a defocusing operation associated with a virtual focal point.

Abstract: Methods, systems, and devices for wireless communications are described in which RF-domain wireless routers may repeat, extend, or redirect beamformed wireless signals received from one or more transmitters to one or more receivers. The router may receive transmissions at a mmW frequency using a first array of antenna elements, and provide the transmissions to a beamforming network, such as a Butler matrix, that outputs one or more a signals to a switching network. The switching network may perform switching to provide the one or more signals to desired inputs of an output beamforming network that outputs beamformed transmission beams via a second array of antenna elements.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques leverage user equipment (UE) functionality to repeat wireless signals received from a base station to one or more other UEs and received from one or more other UEs to the base station. The repeating UE receives, during a transmission time interval reserved for one of uplink communication or downlink communication, a signal from a first device. The UE operates in a time division duplex network. The UE routes the signal, via a radio-frequency (RF) transmission path from an RF receive chain of the UE to an RF transmit chain of the UE. The UE retransmits the signal to a second device during the transmission time interval.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a user equipment and/or base station) may operate in a first mode in a wireless network over a radio frequency spectrum band. The wireless device may receive a signal indicating that a value of the radio frequency spectrum band has satisfied a threshold value. The wireless device may switch, based at least in part on the signal indicating that the value has satisfied the threshold value, from the first mode to a second mode for wireless communications in the wireless network, wherein a first length of a first synchronization signal block associated with the first mode is shorter than a second length of a second synchronization signal block associated with the second mode.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may receive a unicast transmission and may relay the unicast transmission as a multicast transmission to a set of user equipments (UEs). Transmitting the multicast transmission may involve retransmitting the unicast transmission or a signal derived from the unicast transmission in each of a set of beamforming directions. The multicast transmission may be transmitted over multiple antenna arrays or a single antenna array associated with a Butler matrix. Additionally or alternatively, the wireless repeater may receive transmissions from multiple UEs; may form an aggregated signal associated with the received transmissions; and may transmit a unicast transmission associated with the aggregated signal, such as to a base station. The multiple UE transmissions may be received over multiple antenna arrays or over a single antenna array associated with a Butler matrix.
