US-12627970-B2 - UE assistance information for power saving configuration

Abstract

An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.

Description

CROSS REFERENCE TO RELATED APPLICATION(S) This application is a continuation of U.S. Non-provisional application Ser. No. 16/701,062, entitled “UE ASSISTANCE INFORMATION FOR POWER SAVING CONFIGURATION” and filed Dec. 2, 2019, which claims the benefit of U.S. Provisional Application Ser. No. 62/775,790, entitled “UE Assistance Information for Power Saving Configuration” and filed on Dec. 5, 2018, which are expressly incorporated by reference herein in their entirety. BACKGROUND Technical Field The present disclosure relates generally to communication systems, and more particularly, to a communication between a User Equipment (UE) and a base station. Introduction Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by 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 time division synchronous code division multiple access (TD-SCDMA) systems. These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies. SUMMARY The following 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 contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later. A network may control a radio configuration for a user equipment (UE). Aspects presented herein enable the network to determine more effective radio configurations for a particular UE by having the UE provide information about the UE, such as configuration preferences, with the base station. The base station may then determine radio configurations for the UE based on an increased understanding of factors and preferences for the UE. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the UE configuration parameter(s) transmitted to the base station. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided for wireless communication at a base station. The apparatus receives at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the UE configuration parameter(s) received from the UE. To the accomplishment of the foregoing and related ends, the one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.
