Description

MEASUREMENT REPORT INDICATING ONGOING MEASUREMENTS TECHNICAL FIELD [0001] The present disclosure relates to wireless communications, and more specifically to techniques for adding an indication to a measurement report that another measurement is in progress. BACKGROUND [0002] A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an evolved NodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. Each network communication device, such as a base station, may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers). Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology (RAT), fourth generation (4G) RAT, fifth generation (5G) RAT, among other suitable RATs beyond 5G (e.g., sixth generation (6G)). SUMMARY [0003] An article “a” before an element is unrestricted and understood to refer to “at least one” of those elements or “one or more” of those elements. The terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of’ or “one or more of’ or “one or both of’) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. Further, as used herein, including in the claims, a “set” may include one or more elements. [0004] Some implementations of the method and apparatuses described herein may include receiving a reconfiguration first message containing a measurement configuration, where the measurement configuration includes a multiple measurement identities. The method and apparatuses described herein may determine, based on measurements associated with at least a first measurement identity, that a measurement reporting criterion for at least one cell is satisfied, where a measurement or a measurement evaluation associated with a second measurement identity is ongoing. The method and apparatuses described herein may generate a measurement report based on the measurements associated with at least a first measurement identity. The method and apparatuses described herein may determine whether a radio quality of a respective cell satisfies a preliminary radio threshold. The method and apparatuses described herein may add, to the measurement report, an indication that another measurement is in progress and the radio quality of the respective cell satisfies the preliminary radio threshold. The method and apparatuses described herein may transmit a second message comprising the measurement report. [0005] In some implementations, the method and apparatuses described herein transmit, to a UE, a reconfiguration message containing a measurement configuration, where the measurement configuration includes multiple measurement identities. The method and apparatuses described herein may receive, from the UE, a first measurement report based on measurements associated with at least a first measurement identity in the plurality of measurement identities, where the first measurement report further includes an indication that another measurement is in progress and a radio quality of an associated cell satisfies a preliminary radio threshold. The method and apparatuses described herein may start a timer upon reception of the first measurement report and may determine whether one or more second measurement reports are received from the UE prior to expiry of the timer, where the one or more second measurement reports are based on the measurements associated with at least a second measurement identity in the plurality of measurement identities. The method and apparatuses described herein may perform a handover decision for the UE based at least in part on the first measurement report, where the handover decision is further based on the one or more second measurement reports in response to the one or
