Abstract: Wireless communications systems and methods related to coordinated beam refinement and coordinated beam failure recovery (BFR) in a wireless communication network are provided. A first wireless communication device communicates, with a second wireless communication device of a group of wireless communication devices, a communication signal using a first beam characteristic. The first wireless communication device receives, from the second wireless communication device, at least one of beam feedback information or a beam change request. The first wireless communication device transmits, to the group of wireless communication devices in response to the at least one of the beam feedback information or the beam change request, a beam configuration indicating a second beam characteristic to be used by the group of wireless communication devices for communicating with the first wireless communication device, the second beam characteristic being different from the first beam characteristic.

Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a set of patch antennas in a quasi-linear arrangement along a top linear edge and one or more side linear edges of the UE in addition to a curved part between the two linear edges. For example, a first subset of the patch antennas may be linearly arranged on a first edge along the UE (e.g., the top of the UE), a second subset of the patch antennas may be linearly arranged along a second edge of the UE that is at an angle relative to the first edge (e.g., a side of the UE), and at least one patch antenna may be non-linearly arranged (e.g., quasi-linearly) on a curved line formed between the first subset of the patch antennas and the second subset of the patch antennas.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.

Abstract: Aspects of the present disclosure describe configuring a number of antennas in an antenna array to use in communicating in a wireless network. The number of antennas of the antenna array, less than all available antennas for transmission or reception in the antenna array, can be determined such to achieve a radio frequency (RF) power that results in a certain effective data rate for communicating in the wireless network. The number of antennas can be indicated, over a backhaul, to one or more other access points of the wireless network to coordinate using of the number of antennas at a determined time. One or more devices in the wireless network can be communicated with using the number of antennas.

Abstract: Methods, systems, and devices for wireless communication are described. A network server may configure a base station for beamforming communications based on a service type of data used by a user equipment (UE). The network server may determine the service type of the data based on position data of the UE, along with other statistical information related to data usage. The position information may include global position system (GPS) information, gyroscope information, accelerometer information, or information related to the UE's subarray geometry. The base station may receive the position information from the UE and convey it to the network server. The network server may use the position information to generate a network map and to identify the service type of communication.

Abstract: Techniques are described herein for a beam refinement procedure between a first communications device (e.g., base station) and a second communications device (e.g., user equipment (UE)) that uses long-term feedback information from the second communications device to maintain a beam pair link established for a downlink connection. The second communications device may transmit long-term feedback information to the first communications device in response to a request or a trigger event occurring. The long-term feedback information may be sensor information measured by the second communications device or uplink training symbols. The first communications device may localize a beam search of the beam refinement procedure using the long-term feedback information. The localized beam search may be an example of a device-specific search. The first communications device may also generate a long-term map of channel conditions based on the long-term feedback data. The long-term map may also be used to localize the search.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station such as a eNodeB (eNB), a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB)), an indication of a value of a channel quality parameter of a wireless link including a first beam pair between the UE and the base station. The UE may also transmit, to the base station, side information different from and in addition to the indication of the value of the channel quality information, and receive, in response to the transmitted indication of the value and the transmitted side information, an indication of resources for the UE to use to communicate on the wireless link.
