Abstract

A device capable of performing a local operation in a low-interference environment is desired. In one aspect, the device can be a user equipment (UE). The UE transmits a local operation notification to a base station, the local operation notification indicating a local operation that is local to the UE. The UE receives from the base station a resource indicator that indicates one or more resources available for the local operation. The UE performs the local operation using one or more resources.

Description

CROSS-REFERENCE TO RELATED REQUESTS [0001] This Application claims the benefit of U.S. Provisional Patent Application Serial No. 62/383,099, entitled “SIGNALING MECHANISM TO ENABLE SELF-CALIBRATION FOR MILLIMETER-WAVE COMMUNICATION” and filed September 2, 2016, and U.S. Patent Application No. 15/492,600, entitled “SIGNALING MECHANISM TO ENABLE LOCAL OPERATION FOR MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEMS” and filed April 20, 2017, which are expressly incorporated herein by reference in their entirety. BACKGROUND Field [0002] The present invention relates generally to multi-antenna wireless communication systems, and more particularly, to the calibration of user equipment and/or a base station. Background [0003] Wireless communication systems are widely implemented to provide various telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users sharing available system resources. Examples of such multiple access technologies include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, and synchronous time-division code-division multiple access (TD-SCDMA) systems. [0004] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that allows different wireless devices to communicate on a municipal, national, regional, and even global level. An illustrative telecommunications standard is Long Term Evolution (LTE). LTE is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) standard promulgated by the Third Generation Partnership (3GPP) project. LTE is designed to support mobile broadband access through improved spectral efficiency, reduced costs, and enhanced services using OFDMA in the downlink, SC-FDMA in the uplink, and multiple-input multiple-output (MIMO) antenna technology. However, as the demand for mobile broadband access continues to increase, there is a need for further enhancements to LTE technology. These enhancements may also be applicable to other multiple access technologies and to telecommunications standards that employ these technologies. SUMMARY [0005] What follows presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all aspects covered, and is not intended to identify key or critical elements of all aspects, nor to delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified way as a prelude to the more detailed description presented later. [0006] A user equipment (UE) can perform a local operation that is local to the UE and/or a base station can perform a local operation that is local to the base station. One way to perform a local operation, such as over-the-air autocalibration, is to transmit a predefined reference signal from certain antenna elements and perform the local operation based on measurements taken from the transmitted signal. In order to perform the local operation accurately, the propagation of the reference signal from the transmitting antenna elements to the receiving antenna elements must not be affected by interference from other UEs and/or base stations. Additionally, the transmission of the reference signal for the local operation can create undesirable interference for UEs and/or base stations in the vicinity. Therefore, coordination between a UE and a base station may be desirable to minimize interference or other undesirable interference effects during the local operation of a UE or a base station. [0007] In one aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an UE. The UE transmits a local operation notification to a base station, the local operation notification indicating a local operation that is local to the UE. The UE receives, from the base station, a resource indicator that indicates one or more resources available for the local operation. The UE performs the local operation using one or more resources. [0008] In one aspect, the apparatus may be an UE. The UE includes means for transmitting a local operation notification to a base station, the local operation notification indicating a local operation that is local to the UE; means for receiving, from the base station, a resource indicator indicating one or more resources available for the local operation, and means for carrying out the local operation using one or more resources. [0009] In one aspect, the device may be a UE including a memory and at least one processor coupled to the memory. At least one pr
