Problems solved by technology

[0005] However, the number of antenna arrays that can be implemented can be significantly limited by the architecture of the wireless transceiver implemented within the electronic device
For some wireless transceiver architectures, it can be challenging to support multiple antenna arrays and fit within the size constraints of a given electronic device without negatively impacting system performance or increasing cost, especially for portable electronic devices such as smartphones or Wearable device
Therefore, some wireless transceiver architectures may limit the space diversity capability or frequency diversity capability of the electronic device by limiting the number of antenna arrays that the electronic device can support

Embodiment Construction

[0021] Although utilizing multiple antenna arrays can increase the spatial coverage of an electronic device or increase the number of frequency bands supported by an electronic device, it can be challenging to design a wireless transceiver to support multiple antenna arrays and fit within the size constraints of the electronic device without Negatively affect system performance or increase cost. Some wireless transceiver architectures include separate or dedicated transceiver chains for each antenna element within multiple antenna arrays. However, these separate transceiver chains take up space and can limit the number of antenna arrays that can be supported within a smaller electronic device. Therefore, this approach may be impractical for electronic devices where small size or low weight are valued.

[0022] Other wireless transceiver architectures may utilize switches to connect a shared transceiver chain to different antenna elements of different antenna arrays. However,...

Abstract

An apparatus is disclosed for a hybrid wireless transceiver architecture that supports multiple antenna arrays. In an example aspect, the apparatus includes a first antenna array, a second antenna array, and a wireless transceiver. The wireless transceiver includes first dedicated circuitry dedicated to the first antenna array and second dedicated circuitry dedicated to the second antenna array. The wireless transceiver also includes shared circuitry that is shared with both the first antenna array and the second antenna array.

Description

[0001] priority [0002] This patent application claims priority to non-provisional application No. 16 / 140,127, filed September 24, 2018, entitled "HYBRID WIRELESS TRANSCEIVERARCHITECTURE THAT SUPPORTS MULTIPLE ANTENNA ARRAYS," which is assigned to the assignee of this application and is hereby expressly incorporated herein by reference. technical field [0003] The present disclosure relates generally to wireless transceivers, and more particularly to a wireless transceiver that includes respective dedicated and shared circuitry for multiple antenna elements of different antenna arrays. Background technique [0004] Electronic devices use radio frequency (RF) signals to communicate information. These radio frequency signals allow users to talk to friends, download information, share pictures, remotely control home devices, receive global positioning information, employ radar for object detection and tracking, listen to radio stations, and more. To increase spatial covera...
