Abstract

A system and a method are disclosed for implementing reporting timeline determination relating to UE-initiated beam reporting procedures. The reporting timeline determination may enable selection of the received beams to measure and include in the UE-initiated beam report in a manner that realizes improvements to beam reporting, including improving the accuracy and/or reliability of the information contained in the UE-initiated beam reports and reducing latency associated with the UE-initiated beam reporting transmissions. For example, a method may include transmitting a beam reporting indication message in the first uplink channel to initiate beam reporting, identifying a reference resource based on the second uplink channel and identifying beams to measure based on a relation of the beams to the reference resource. Measurements on the identified beams may be performed, and the beam report may be transmitted in the second uplink channel based on the measurement of the beams.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 63/717,693, filed on Nov. 7, 2024, the disclosure of which is incorporated by reference in its entirety as if fully set forth herein. BACKGROUND 1. Field Aspects of some embodiments of the present disclosure generally relate to wireless communication systems. More particularly, the subject matter disclosed herein relates to improvements to beam management, including to beam reporting. 2. Description of the Related Art Beam management may be utilized in wireless communication technology standards, such as 5G NR (New Radio) technology, for establishing, maintaining, and/or improving (e.g., optimizing) the directional transmission beams and reception beams between a general node B (gNB) (also referred to herein as a “base station”) and the User Equipment (UE). For example, wireless networks using 5G NR technology may often operate at relatively higher frequencies (e.g., 24.25 GHz to 71.0 GHz for high speeds and capacity), thereby signals may be more directionally driven and/or susceptible to blockage, path loss, and/or the like. Beam management may involve functions to assist in improving the strength, directional accuracy, quality, and reliability of beams in the wireless network. Beam management may involve serval functions that relate to the control and/or improved operation of the beams, including, but not limited to: beam sweeping; beam measurement; beam determination; beam reporting; and/or the like. As used herein, “beam reporting” may refer to the algorithms, functions, and procedures in some wireless communication technology standards (e.g., 5G NR) that involve the UE communicating to the network, via the gNB, information relating to the signal qualities of various transmitted beams. Beam reporting may allow the gNB to maintain appropriate and/or improved signal quality, for example switching beams in order to achieve an improved operational performance and/or stability (e.g., uninterrupted data transfer). During beam reporting, UEs may perform measurements on candidate beams transmitted by a gNB and report the results, which can be used for beam selection, tracking, and recovery in response to channel dynamics, mobility, and/or beam failure. The above information disclosed in this Background section is for enhancement of understanding of the background of the present disclosure, and therefore, it may contain information that does not constitute prior art. TECHNICAL FIELD The disclosure generally relates to wireless communication networks. More particularly, the subject matter disclosed herein relates to improvements to beam management, including reporting timeline determination for beam reporting. SUMMARY Aspects of some embodiments of the present disclosure generally relate to improvements to beam management, including reporting timeline determination for beam reporting. In some embodiments, a method for transmitting a beam report using a first uplink channel and a second uplink channel, may include: transmitting a beam reporting indication message in the first uplink channel to initiate beam reporting; identifying, at a User Equipment (UE), a reference resource based on the second uplink channel; identifying one or more beams to measure based on a relation of the one or more beams to the reference resource; performing measurements on the one or more beams; and transmitting the beam report in the second uplink channel based on the measurement of the one or more beams. In some embodiments, the reference resource may be a Channel State Information (CSI) reference resource. In some embodiments, identifying the reference resource may be based on determining a time for the CSI reference resource based on an aperiodic CSI reporting for the CSI reference resource. In some embodiments, identifying the reference resource may be based on determining a time for the CSI reference resource relative to an uplink slot corresponding to the second uplink channel. In some embodiments, determining the time for the CSI reference resource is based on a downlink slot corresponding to the CSI reference resource relative to the uplink slot. In some embodiments, determining the time for the CSI reference resource may be based on a subcarrier spacing configuration for the downlink slot and an offset value. In some embodiments, identifying the one or more beams to measure may be based on determining the one or more beams that are received at the UE before the determined time for the CSI reference resource. In some embodiments, a method for transmitting a beam report using a first uplink channel and a second uplink channel may include: transmitting a beam reporting indication message in the first uplink channel to initiate beam reporting; identifying, at a UE, a reference resource based on the first uplink channel; identifying one or more beams to measure based on a relation of the on
