AI Technical Summary
The challenge in 5G NR networks is the increased power consumption and prolonged measurement delays due to multiple-Rx simultaneous reception for SSB and CSI-based L3/L1 measurements, necessitating conditions for proper activation and deactivation of multi-Rx operation to balance power consumption and delay reduction.
Implementing triggering conditions based on events such as handover, cell search, and signal quality to activate multi-Rx operation only when necessary, reducing Rx beam sweeping factor and thereby decreasing measurement delays while conserving power.
This approach effectively reduces measurement delays and power consumption by enabling multi-Rx operation only under specific conditions, optimizing UE performance in 5G NR networks.

Description
METHODS AND APPARATUS FOR ENABLING MULTIPLE RECEIVER OPERATION IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 631,546, filed 9 April 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to determining whether to enable multiple-receiver (multi-Rx) operation with respect to user equipment and network apparatus in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] In the fifth generation (5G) New Radio (NR) , radio resource management (RRM) is one of the major techniques for 5G networks. RRM involves sharing of the scarce spectrum among all users of the system. It includes performance gains in terms of efficient energy usage, higher throughput, lower delays, and decreased packet loss. On the other hand, in 5G NR, the synchronization signal and physical broadcast channel block (SSB) consists of multiple SSBs. These multiple SSBs are associated with the different SSB indexes and with the different transmission beams can be configured for beam management and measurement. The measurement procedure is a user equipment (UE) power consuming procedure. On the configured SSBs, a UE will conduct the radio link monitoring / radio resource management measurement. This is also a time-consuming procedure if a UE needs to perform a receiver (Rx) beam sweeping.
[0005] The RRM delay requirements for SSB based layer 3 (L3) or layer 1 (L1) measurements in frequency range 2 (FR2) can be very long due to the Rx beam sweeping factor. When a UE performs SSB based L3 / L1 measurements in FR2 with N Rx beam sweeping, the overall measurement delay will be scaled up by the corresponding N factor used for beam sweeping. For the UE capable of multiple-Rx simultaneous reception, the beam sweeping can be performed simultaneously using multiple-Rx such that Rx beam sweeping factor can be reduced accordingly. As a result, the delay of FR2 SSB based L3 / L1 measurements can be reduced significantly. This solution can also be extended to FR2 channel state information (CSI) -based L3 / L1 measurements.
[0006] However, this reduction / optimization of the measurement delay comes at the cost of increased power consumption when using multiple-Rx simultaneous reception. Therefore, specific conditions need to be introduced for applying this optimization of using multiple-Rx simultaneous reception for delay reduction of FR2 SSB / CSI based L3 / L1 measurements.
[0007] Accordingly, how to properly activate the multiple-Rx simultaneous reception in view of power consumption management becomes an important issue in the newly developed wireless communication network. Therefore, there is a need to provide proper schemes / conditions for enabling the multiple-Rx operation.SUMMARY
[0008] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0009] An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issue pertaining to determining whether to enable multi-Rx operation with respect to user equipment (UE) and network apparatus in mobile communications.

The method may further involve the apparatus enabling a multi-Rx operation in an event that the triggering condition is met. The method may further involve the apparatus performing a measurement based on the multi-Rx operation.
[0011] In one aspect, an apparatus may comprise a transceiver which, during operation, wirelessly communicates with a network node. The apparatus may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising receiving, via the transceiver, a signal from a network node.

[0017] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0018] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to determining whether to enable multi-Rx operation in mobile communications, which may ensure correct UE operations. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0019] FIG. 1 illustrates an example scenario 100 of a communication environment in which various solutions and schemes in accordance with the present disclosure may be implemented. Scenario 100 involves a user equipment (UE) 110 in wireless communication with a wireless network (e.g., a 5G NR or 6G network) consisting of an access network 120 and a core network 130. The UE 110 may be a smart phone, a wearable device, an IoT device, and a tablet, etc. Alternatively, the UE 110 may be a notebook (NB) or personal computer (PC) inserted or installed with a data card which includes a modem and multiple radio frequency (RF) transceivers to provide the functionality of wireless communication. In 5G NR, the access network 120 is connected to the core network 130 by means of the NG interface, more specifically to a user plane function (UPF) by means of the NG user-plane part (NG-u) , and to a mobility management function (AMF) by means of the NG control-plane part (NG-c) . One base station (BS) or network node such as a next generation Node-B (gNB) can be connected to multiple UPFs / AMFs for the purpose of load sharing and redundancy. In addition, the core network may include other entities, such as session management function (SMF) and unified data management (UDM) , etc. The access network 120 may include multiple BSs (e.g., BS 121) , each BS may provide communication coverage for a geographic coverage area (e.g., a cell) where communications with the UE 110 is supported.
[0020] The UE may comprise multiple receivers and may be able to perform multiple-Rx simultaneous reception. That is, the UE may comprise multiple Rx chains, each may comprise necessary radio frequency (RF) components for receiving signals from the BS (e.g., SSBs and / or CSI reference signals) . These Rx chains may be activated to receive and process signals simultaneously. When the UE operates in a connected mode, the UE may be configured to perform measurements for RRM. Specifically, the UE may need to perform SSB / CSI based L3 / L1 measurements with Rx beam sweeping. The overall measurement delay will depend on the corresponding Rx beam sweeping factor (e.g., N factor) . For example, N factor can be up to 8 for FR2-1 and can be up to 12 for FR2-2. For the UE with multiple-Rx capability, the beam sweeping can be performed simultaneously by enabling multiple-Rx simultaneous reception such that Rx beam sweeping factor can be reduced accordingly (i.e., faster beam sweeping) . This is also called beam sweeping factor (BSF) reduction capability. For example, the Rx beam sweeping factor may be reduced by X (e.g., N / X) with the multiple-Rx simultaneous reception. As a result, the delay of SSB / CSI based L3 / L1 measurements can be reduced significantly.
[0021] However, enabling multiple-Rx simultaneous reception (or faster beam sweeping) will increase UE power consumption since multiple Rx chains are activated simultaneous. If the UE always turn on multiple-Rx simultaneous reception or enable multiple-Rx simultaneous reception frequently, the UE power will be drained quickly. Due to power consumption concerns, the present disclosure proposes several conditions / restrictions for the UE capable of multiple-Rx simultaneous reception to determine the proper scenarios / timing to activate / deactivate the multiple-Rx operation. This can be applied for FR2 SSB / CSI based L3 / L1 measurements in connected mode, or other scenarios / frequency ranges suitable for multiple-Rx simultaneous reception.
[0022] Specifically, the UE may receive a signal from a network node (e.g., BS 121) . The signal may comprise a higher layer signal (e.g., radio resource control (RRC) message) , a command, a reference signal or other signals. The UE may determine whether a triggering condition is met according to the signal. In an event that the triggering condition is met, the UE may enable / activate the multi-Rx operation (i.e., multiple-Rx simultaneous reception) . Then, the UE may perform a measurement (e.g., FR2 SSB / CSI based L3 / L1 measurement) based on the multi-Rx operation. Thus, the UE may reduce the beam sweeping factor (e.g., N factor) by enabling the multi-Rx operation. When the triggering condition is not met or is terminated, the UE may disable / deactivate the multi-Rx operation to save UE power. Accordingly, the UE can properly enable the multi-Rx operation only when necessary (i.e., according to the triggering condition) and disable the multi-Rx operation for power saving.
[0023] The triggering conditions may be based on one-time events or procedures that does not happen frequently. In some implementations, the triggering conditions may be based on a handover event. The UE may receive an RRC message from a network node. The triggering condition may comprise that the RRC message implies / indicates a handover event (e.g., handover to a target NR cell in FR2) . The handover delay / interruption time can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 cell is unknown, cell search delay Tsearch can be reduced) .
[0024] In some implementations, the triggering conditions may be based on a dual active protocol stack (DAPS) handover event. The UE may receive an RRC message from a network node. The triggering condition may comprise that the RRC message implies / indicates a DAPS handover event (e.g., DAPS handover to a target NR cell in FR2) . The DAPS handover delay / interruption time can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 cell is unknown, cell search delay Tsearch can be reduced) .
[0025] In some implementations, the triggering conditions may be based on a handover with primary secondary cell (PSCell) event. The UE may receive an RRC message from a network node. The triggering condition may comprise that the RRC message implies / indicates a handover with PSCell event (e.g., handover to a PSCell in FR2) . The handover delay / interruption time can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 PCell is unknown, PCell search delay Tsearch can be reduced) . In addition, the PSCell addition / change delay can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 PSCell is unknown, PSCell search delay Tsearch can be reduced) .
[0026] In some implementations, the triggering conditions may be based on a secondary cell (SCell) activation event. The UE may receive an activation command (e.g., SCell activation command) from a network node. The triggering condition may comprise that the activation command implies / indicates an activation of an SCell. The SCell activation delay can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 SCell is unknown, SCell search delay Tsearch can be reduced) .
[0027] In some implementations, the triggering conditions may be based on a PSCell addition event. The UE may receive an RRC message from a network node. The triggering condition may comprise that the RRC message implies / indicates an addition of a PSCell. The PSCell addition delay can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 PSCell is unknown, PSCell search delay Tsearch can be reduced) .
[0028] In some implementations, the triggering conditions may be based on a secondary cell group (SCG) activation event. The UE may receive an activation command (e.g., SCG activation command) from a network node. The triggering condition may comprise that the activation command implies / indicates an activation of a PSCell. The SCG activation delay can be reduced by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception (e.g., when target FR2 PSCell is unknown, PSCell search delay Tsearch can be reduced) .
[0029] The triggering conditions may also be based on other factors. In some implementations, the triggering conditions may be based on a signal quality of serving cell or a UE location. The UE may measure a signal from a serving cell and determine a signal quality (e.g., at least one of reference signal received power (RSRP) , reference signal received quality (RSRQ) and signal-to-noise and interference ratio (SINR) threshold (s) ) . The UE may determine whether it is at the cell center or at the cell edge according the signal quality. The triggering condition may comprise that the UE is in a cell edge or a signal quality of a serving cell is less than a threshold (i.e., fulfilling cell edge criterion or not fulfilling not-at-cell edge criterion) . The FR2 SSB / CSI based L3 / L1 measurement delay reduction, by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception, can be applied when the UE is in cell-edge area (or not in cell-center area) . For example, when the UE measurement for serving cell’s signal quality (e.g., RSRP / RSRQ / SINR) becomes less than a threshold (i.e., not fulfilling not-at-cell edge criterion) , the UE may activate the multiple-Rx simultaneous reception. Otherwise, the UE may deactivate the multiple-Rx simultaneous reception.
[0030] In some implementations, the triggering conditions may be based on UE’s mobility. The UE may determine its mobility or a signal quality variation (e.g., delta value) of a serving cell. The UE may receive some signals or location information from the serving cell to determine its mobility or the signal quality variation. The triggering condition may comprise that the UE is in a high mobility (or not fulfill low mobility criterion) or a signal quality variation of a serving cell is larger than a threshold. The FR2 SSB / CSI based L3 / L1 measurement delay reduction, by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception, can be applied when the UE is in high mobility or a signal quality variation of a serving cell is larger than a threshold. For example, when the UE does not fulfil low mobility criterion, the UE may activate the multiple-Rx simultaneous reception. Otherwise, the UE may deactivate the multiple-Rx simultaneous reception.
[0031] In some implementations, the triggering conditions may be based on both the cell edge criterion (or not-at-cell edge criterion) and the low mobility criterion. The FR2 SSB / CSI based L3 / L1 measurement delay reduction, by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception, can be applied when both criteria are fulfilled.
[0032] In some implementations, the triggering conditions may be based on knowledge of a target cell for different RRM events / procedures. The UE may be configured to initiate a specific RRM events / procedure associated with a target cell. The UE may determine whether the target cell is known or unknown for the specific RRM events / procedure. The triggering condition may comprise that a target cell is unknown for a specific RRM events / procedure. The FR2 SSB / CSI based L3 / L1 measurement delay reduction, by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception, can be applied when a target cell is unknown for a specific RRM event / procedure.
[0033] In some implementations, the triggering conditions may be based on knowledge of a transmission configuration indication (TCI) state for different RRM events / procedures. The UE may be configured to initiate a specific RRM events / procedure associated with a TCI state. The UE may determine whether the TCI state is known or unknown for the specific RRM events / procedure. The triggering condition may comprise that a TCI state is unknown for a specific RRM events / procedure. The FR2 SSB / CSI based L3 / L1 measurement delay reduction, by reducing Rx beam sweeping factor using multiple-Rx simultaneous reception, can be applied when a TCI state is unknown for a specific RRM event / procedure.

[0054] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0055] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0056] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms.
