Abstract

Methods, systems, and devices for wireless communications are described for capability indications by a reduced capability user equipment (UE) and UE-based performance measurement parameter reporting or self-organizing network (SON) parameter reporting based on the capability indications. A reduced capability UE may transmit a set of capabilities to a base station that indicate various types of parameter reporting that are supported at the UE. The base station may identify the UE as a reduced capability device, and set one or more reporting parameters based on the indicated UE capabilities. The base station may provide a reporting configuration to the UE with the one or more reporting parameters, and the UE may provide reporting of measured parameters (e.g., performance measurement parameter reporting or SON parameter reporting) based on the reporting configuration.

Description

FIELD OF TECHNOLOGY The following relates to wireless communications, including parameter reporting techniques for reduced capability user equipment. BACKGROUND Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE). SUMMARY The described techniques relate to improved methods, systems, devices, and apparatuses that support parameter reporting techniques for reduced capability user equipment. In various aspects, described techniques provide for a user equipment (UE) that may have reduced capabilities relative to one or more other UEs, and such UEs having reduced capabilities may be referred to as reduced capability or RedCap devices. In some cases, a reduced capability UE (or other device) may transmit a set of capabilities to a base station, that indicate capabilities for UE-based performance measurement parameter reporting or self-organizing network (SON) parameter reporting. In some cases, one or more capabilities of the set of capabilities indicate that the UE is a reduced capability device (e.g., has a capability that is below a threshold capability value for one or more UE-based performance measurement parameters or self-organizing network parameters). The base station may identify the UE as a reduced capability device, and set one or more reporting parameters based on the indicated UE capability. The base station may provide a reporting configuration to the UE with the one or more reporting parameters, and the UE may provide reporting of measured parameters (e.g., performance measurement parameter reporting or SON parameter reporting) based on the reporting configuration. A method for wireless communication at a user equipment (UE) is described. The method may include transmitting, to a base station, a set of capabilities of the UE for UE-based performance measurement parameter reporting or self-organizing network parameter reporting, where one or more capabilities of the set of capabilities indicate that the UE has a capability that is below a threshold capability value for one or more UE-based performance measurement parameters or self-organizing network parameters and receiving, responsive to the transmitted set of capabilities, an indication from the base station of a reporting configuration for the UE-based performance measurement parameter reporting or the self-organizing network parameter reporting. An apparatus for wireless communication at a UE is described. The apparatus may include at least one processor, and memory coupled (e.g., operatively, communicatively, functionally, electronically, or electrically) with the at least one processor, the memory storing instructions executable by the at least one processor to cause the UE to transmit, to a base station, a set of capabilities of the UE for UE-based performance measurement parameter reporting or self-organizing network parameter reporting, where one or more capabilities of the set of capabilities indicate that the UE has a capability that is below a threshold capability value for one or more UE-based performance measurement parameters or self-organizing network parameters and receive, responsive to the transmitted set of capabilities, an indication from the base station of a reporting configuration for the UE-based performance measurement parameter reporting or the self-organizing network parameter reporting. Another apparatus for wireless communication at a UE is described. The apparatus may include means for transmitting, to a base station, a set of capabilities of the UE for UE-based performance measurement parameter reporting or self-organizing network parameter reporting, where one or more capabilities of the set of capabilities indicate that the UE has a capability that is below a threshold capability value for one or more UE-based performance measurement parameters or self-organizing network parameters and means for receiving, responsive to the transmitted set of capabilities, an
