Existing technologies face challenges in efficiently reducing Layer 3 measurement delay and power consumption for user equipment (UE) operating in Frequency Range 2-1 (FR2-1) by optimizing receiving beam sweeping, particularly for UEs capable of multiple-receiver simultaneous reception.
A multiple-receiver measurement mode is activated based on a configuration with set thresholds, allowing simultaneous measurements across multiple receiving chains when the signal quality of a neighboring cell exceeds that of the serving cell, thereby reducing beam sweeping factors and enhancing measurement efficiency.
This approach effectively decreases measurement delay and power consumption while maintaining high throughput by enabling simultaneous multi-beam measurements, thus optimizing UE performance in FR2-1 environments.

In the following, unless explicitly stated, a resource in both frequency domain and time domain will be used as an example of a transmission resource for describing some example embodiments of the present disclosure. It is noted that example embodiments of the present disclosure are equally applicable to other resources in other domains.
[0042] Since the beginning of 5G NR, a UE operating at higher carrier frequencies, known as Frequency Range 2 (FR2) , may require a degree of UE reception beamforming. The UE in FR2 may possess more than one antenna panel. An antenna panel is a circuit element that contains multiple antenna elements, which can be used for analog beam forming in FR2. Each panel may be capable of generating one or more beams. Accordingly, the UE may be capable of monitoring a single beam or more beams on each panel. If the UE has more panels and receiving chains, the UE may be able to monitor multiple beams at the same time. A three-panel setup is possible in the UE. However, there are no specific requirements for the UE regarding the number of panels.
[0043] For NR to function effectively in FR2, both the network (such as gNB) and the UE may need to employ a form of beamforming. Beamforming refers to applying of one or more optimized antenna spatial settings to direct transmission or reception in a specific direction. The system with beamforming differs from previous systems not operating in FR2, where omni-directional reception and transmission are the norm.
[0044] In the context of reception beamforming, it is assumed that the UE only receives signals from a restricted spatial area, limiting reception from outside this area. A UE operating in FR2 may need to receive with all panels active simultaneously or in time division multiplexing mode to cover measurements in all directions. However, constantly activating all panels in FR2 may increase power consumption. Therefore, it is decided in the early stages of NR that the UE operating in FR2 may not need to continuously activate all panels for tasks such as L3 measurements. Instead, the minimum requirement is that the UE only needs to have one panel active for one measurement, which, however, may increase latencies as the UE needs to sweep over all panels for 360-degree spherical coverage measurements.
[0045] The delay corresponding to cell detection and L3 measurements is discussed in the 3GPP standards such as TS 38.133. Regarding intra-frequency cell identification, the UE may be able to identify a detectable intra-frequency cell within Tidentify_intra_without_index if the UE is not indicated to report an SSB based radio resource management (RRM) measurement result with an associated SSB index (for example, reportQuantityRsIndexes or maxNrofRSIndexesToReport is not configured for the UE) , or the UE is indicated that a neighbor cell is synchronous with a serving cell (for example, deriveSSB-IndexFromCell is enabled) . The UE may be able to identify a detectable intra-frequency synchronization signal (SS) block of an already detected cell within Tidentify_intra_without_index. It is assumed that deriveSSB-IndexFromCell is enabled for Frequency Range 1 (FR1) Time Division Duplex (TDD) and FR2 with a sub-carrier space (SCS) smaller or equal to 480 kHz.
[0046] Tidentify_intra_without_index may be calculated as below: Tidentify_intra_without_index = (TPSS / SSS_sync_intra + T SSB_measurement_period_intra) ms.
[0047] TPSS / SSS_sync_intra is a time period used in Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS) detection. TPSS / SSS_sync_intra is given in Table 1 (such as Table 9.2.5.1-11 in TS 38.133) and Table 2 (such as Table 9.2.5.1-2 in TS 38.133) . TSSB_measurement_period_intra is equal to a measurement period of an SSB based measurement and is also given in Table 1 and Table 2.
[0048] Table 1: Time period for PSS / SSS detection (FR2)
[0049] Table 2: Measurement period for intra-frequency measurements without gaps (FR2)
[0050] For a UE supporting power class 2, Mpss / sss_sync_w / o_gaps =24. For a UE supporting FR2-1 power class 3, Mpss / sss_sync_w / o_gaps =24. For a UE supporting FR2-1 power class 4, Mpss / sss_sync_w / o_gaps =24. For a UE supporting FR2-1 power class 2, Mmeas_period_w / o_gaps =24. For a UE supporting FR2-1 power class 3, Mmeas_period_w / o_gaps =24. For a UE supporting power class 4, Mmeas_period_w / o_gaps =24.
[0051] As may be seen from above description, the corresponding delay parts for identifying an intra-frequency cell contains a scaling factor for FR2 which are “Mpss / sss_sync_w / o_gaps” and “Mmeas_period_w / o_gaps” . The current values of (Mpss / sss_sync_w / o_gaps=24) and (Mmeas_period_w / o_gaps =24) are determined under consideration of various UE implementations, specifically focusing on aspects of cell detection and measurement, and under assumptions pertaining to the applying of UE beamforming during these procedures.
[0052] The overall measurement delay may be reduced by redcing Tidentify_intra_without_index. In addition, the network can configure a longer STMC in combination of FBS. That may reduce the measurement procedure overhead, e.g. reducing scheduling restrictions.
[0053] Thus, as mentioned above, for a UE capable of multiple-receiver simultaneous reception on a single FR2 carrier, reduction of a L3 measurement duration is an objective of the current WI. However, constant usage of multiple-receiver reception may bring higher energy consumption for a UE. For a UE capable of multiple-receiver reception, a solution which reduces a beam sweeping factor during a specific condition may not only reduce the L3 measurement delay, but also reduce UE power consumption. For instance, if a neighboring cell is hysteresis better than a serving cell, in a dense deployment, the UE needs to change the cell rapidly.
[0054] Example embodiments of the present disclosure propose a solution to activate a multiple-receiver measurement mode. In this solution, a first apparatus (such as a UE) receives, from a second apparatus (such as a gNB) , a configuration for enabling a multiple-receiver measurement mode for at least one cell. The configuration may include at least one set of thresholds (where a set of thresholds may include one or more thresholds) for activating the multiple-receiver measurement mode for the at least one cell. Based on the received configuration, the first apparatus determines whether the multiple-receiver measurement mode is applied for the at least one cell, and then performs at least one measurement (such as L3 measurement) for the at least one cell, accordingly. In the multiple-receiver measurement mode, the first apparatus 110 may perform measurements and cell detection simultaneously over a plurality of receiving chains.
[0055] With the proposed solution, the multiple-receiver measurement mode may be activated when needed. By using the multiple-receiver measurement mode, the first apparatus may be able to measure a plurality of beams at the same time, and thus the measurement delay at the first apparatus may be decreased effectively and efficiently. This solution enables the shorter measurement delay and higher UE power consumption to have a trade-off, which brings higher throughput.
[0056] FIG. 1 illustrates an example communication environment 100 in which example embodiments of the present disclosure can be implemented. In the communication environment 100, a plurality of communication devices, including a first apparatus 110 and a second apparatus 120, can communicate with each other.
[0057] In the following, for the purpose of illustration, some example embodiments are described with the first apparatus 110 operating as a terminal device and the second apparatus 120 operating as a network device. However, in some example embodiments, operations described in connection with a terminal device may be implemented at a network device or other devices, and operations described in connection with a network device may be implemented at a terminal device or other devices.
[0058] In some example embodiments, if the first apparatus 110 is a terminal device and the second apparatus 120 is a network device, a link from the second apparatus 120 to the first apparatus 110 is referred to as a downlink (DL) , while a link from the first apparatus 110 to the second apparatus 120 is referred to as an uplink (UL) . In DL, the second apparatus 120 is a transmitting (TX) device (or a transmitter) and the first apparatus 110 is a receiving (RX) device (or a receiver) . In UL, the first apparatus 110 is a TX device and the second apparatus 120 is a RX device.
[0059] Communications in the communication environment 100 may be implemented according to any proper communication protocol (s) , comprising, but not limited to, cellular communication protocols of the first generation (1G) , the second generation (2G) , the third generation (3G) , the fourth generation (4G) , the fifth generation (5G) , the sixth generation (6G) , and the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any proper wireless communication technology, comprising but not limited to: Code Division Multiple Access (CDMA) , Frequency Division Multiple Access (FDMA) , Time Division Multiple Access (TDMA) , Frequency Division Duplex (FDD) , Time Division Duplex (TDD) , Multiple-Input Multiple-Output (MIMO) , Orthogonal Frequency Division Multiple (OFDM) , Discrete Fourier Transform spread OFDM (DFT-s-OFDM) and / or any other technologies currently known or to be developed in the future.
[0060] In the environment 100, the first apparatus 110 may have access to a communication network via a plurality of cells, including a first cell 121 and a second cell 122 for CA, for example. Either or both cells may be provided by the second apparatus 120 or any other suitable devices which may employ the same or different radio access technology. In some example embodiments, the first cell 121 may be a serving cell, and the second cell 122 may be a neighbor cell. Although two cells 121 and 122 are shown in FIG. 1, less or more cells may be provided for the first apparatus 110.
[0061] In some example embodiments, both the first apparatus 110 and the second apparatus 120 may be configured to implement a beamforming technique and communicate with each other via a plurality of beams. As shown in FIG. 1, the first apparatus 110 may be configured with a plurality of beams 130-1, …, 130-N, and the second apparatus 120 may be configured with a plurality of beams 135-1, 135-2, …, 135-M, where N and M represent any positive integer. There may be different beams configured for the first cell 121 and the second cell 122. For example, a beam 135-2 may be configured for the second cell 122. It is to be understood that the second cell 122 may have more beams associated therewith. Although not shown, the first cell 121 may also have beams associated therewith.
[0062] It is to be understood that the numbers of apparatuses, cells and beams are only for the purpose of illustration without suggesting any limitations. The communication environment 100 may include any suitable numbers of apparatuses, cells and beams adapted for implementing embodiments of the present disclosure.
[0063] In the environment 100, the first apparatus 110 may apply a multiple-receiver measurement mode for at least one cell. The applying of the multiple-receiver measurement mode may be based on a configuration from the second apparatus 120. This configuration may be used to enable the multiple-receiver measurement mode for the at least one cell.
[0064] In some example embodiments, the configuration may comprise at least one set of thresholds for activating the multiple-receiver measurement mode for the at least one cell. For example, the first apparatus 110 with multiple-receiver (or Rx) reception capability may be required to perform measurements on a carrier frequency by applying fast beam sweeping (FBS) when a signal quality of a neighboring cell (also called a neighboring cell quality) is threshold-better than a signal quality of a serving cell (also called a serving cell quality) . Hence, the first apparatus 110 may enable a multiple-receiver (multiple-Rx) measurement mode (or a multiple-Rx reception mode) and perform the measurement in a faster manner.
[0065] The FBS means a reduced beam sweeping factor to be used. For example, if the neighboring cell quality is threshold better than the serving cell quality, a receiving beam sweeping factor is reduced for the first apparatus 110 that may operate in FR2-1, for example.
[0066] FIGS. 2A and 2B show example processes of receiving beam sweeping used for measurements according to some example embodiments of the present disclosure. In a process 200A, the multiple-receiver measurement mode is disabled. In this case, beam sweeping is performed over one receiving chain, using one receiving beam. In a process 200B, the multiple-receiver measurement mode is activated where beam sweeping is performed over a plurality of receiving chains, using two simultaneous receiving beams. As shown in FIGS. 2A and 2B, the use of multiple receivers (or receiving chains) may reduce the time for measuring all 8 beam directions. In this way, the shorter measurement delay and higher UE power consumption may have a trade-off, which may bring higher throughput.
[0067] FIG. 3 shows a signaling diagram 300 of communication between the first apparatus 110 and the second apparatus 120 for activation of a multiple-receiver measurement mode according to some example embodiments of the present disclosure.
[0068] As shown in FIG. 3, the second apparatus 120 (such as a gNB) transmits (305) , to the first apparatus 110 (such as a UE) , a configuration for enabling a multiple-receiver measurement mode for at least one cell. In some example embodiments, the configuration may include at least one set of thresholds for activating the multiple-receiver measurement mode for the at least one cell where a set of thresholds may include one or more thresholds. In some example embodiments, the configuration may comprise at least one condition for activating the multiple-receiver measurement mode for the at least one cell. In some other examples, one or more thresholds and / or at least one condition for activating the multiple-receiver measurement mode may be specified or predefined in the 3GPP standards.
[0069] After the first apparatus 110 receives (310) the configuration, the first apparatus 110 determines (315) , based on the configuration, whether the multiple-receiver measurement mode is applied for the at least one cell. For example, after the first apparatus 110 receives (310) the configuration, the first apparatus 110 may know that the multiple-receiver measurement mode is enabled for the at least one cell. Then, the first apparatus 110 may determine whether to apply the multiple-receiver measurement mode, based on some rules.
[0070] In some example embodiments, the at least one cell may comprise at least one neighbor cell. For a neighbor cell of the at least one neighbor cell, the first apparatus 110 may determine whether the multiple-receiver measurement mode is applied, based on measurements for a serving cell and the neighbor cell. In some example embodiments, the first apparatus 110 may determine whether the multiple-receiver measurement mode is applied for the neighbor cell, based on a comparison between at least one threshold and a difference of a signal quality of the neighbor cell (represented by Qneighbor) minus a signal quality of a serving cell (represented by Qserv) .
[0071] In an example, the second apparatus 120 may configure, or based on the specification, one or more thresholds for a cell quality difference between the serving cell and the neighboring cell to indicate when FBS is applied. Using the thresholds, the first apparatus 110 may determine when to apply FBS. This can be achieved by reduce a beam sweeping factor (BSF) . For example, a beam sweeping factor (BSF) may be reduced based on the cell quality difference between the serving and neighboring cells, e.g., (Qneighbor -Qserv) . The reduced BSF may reduce measurement overhead and make the measurement faster.
[0072] In some example embodiments, the at least one threshold may comprise a first threshold. If the difference of the signal quality of the neighbor cell minus the signal quality of the serving cell is greater than or equal to the first threshold, the first apparatus 110 may determine that the multiple-receiver measurement mode is applied or activated for the neighbor cell. Alternatively, or in addition, if the difference is less than the first threshold, the first apparatus 110 may determine that the multiple-receiver measurement mode is disabled or deactivated for the neighbor cell.
[0073] FIG. 4 shows an example process for activating FBS for a neighbor cell based on a quality difference (Qneighbor –Qserv) and the condition according to some example embodiments of the present disclosure.
[0074] As shown in FIG. 4, in a time period 405, the quality difference (Qneighbor –Qserv) is below a threshold 407, the first apparatus 110 may determine that FBS is deactivated for the neighbor cell. The threshold 407 may be both positive (if Qneighbor >Qserv) , or negative (if Qneighbor < Qserv) . In a time period 410, the quality difference (Qneighbor –Qserv) goes above the threshold 407, the first apparatus 110 may determine that FBS is activated for the neighbor cell. In a time duration 415, the quality difference (Qneighbor –Qserv) becomes lower than the threshold 407, the first apparatus 110 may determine that FBS is deactivated for the neighbor cell.
[0075] In some example embodiments, more than one threshold may be used. For example, a threshold can be set for when to enable the FBS, and a lower threshold for when to disable the FBS. Then, in the area between these thresholds, the first apparatus 110 may find a spot to apply the FBS. In this way, a hysteresis may be defined around the one or more thresholds, thereby avoiding too much toggling between FBS and legacy BSF, or between the different values of the BSF.
[0076] For example, in some example embodiments, the at least one threshold may comprise a first threshold and a second threshold smaller than the first threshold. If the difference is greater than or equal to the first threshold, the first apparatus 110 may determine that the multiple-receiver measurement mode is applied for the neighbor cell. If the difference is less than the second threshold, the first apparatus 110 may determine that the multiple-receiver measurement mode is disabled for the neighbor cell. In this way, too much toggling between FBS and legacy beam sweeping or between the different values of the BSF may be reduced.
[0077] Based on the determining (315) , as shown in FIG. 3, the first apparatus 110 performs (320) at least one measurement for the at least one cell. In some example embodiments, if the first apparatus 110 determines (315) that the multiple-receiver measurement mode is disabled for the at least one cell, the first apparatus 110 may perform the at least one measurement for the at least one cell using a first beam sweeping factor. If the first apparatus 110 determines (315) that the multiple-receiver measurement mode is applied for the at least one cell, the first apparatus 110 may perform the at least one measurement for the at least one cell using a second beam sweeping factor smaller than the first beam sweeping factor.
[0078] By way of example, in the case that the first apparatus 110 supports simultaneous multi-reception, if a threshold difference (e.g., a difference above a threshold) is detected between the quality of the serving cell and the neighboring cell, the multiple-receiver mode (or a multi-reception mode) allows the first apparatus 110 to be able to measure multiple beams at the same time, thereby improving the efficiency of the beam sweeping and the cell measurement. If the first apparatus 110 is close to a cell edge, it may be beneficial to start doing measurements more often in case of a handover is needed.
[0079] In some example embodiments, the at least one measurement may comprise at least one layer 3 measurement. For example, the first apparatus 110 may perform L3 measurements using FBS, if the multiple-receiver measurement mode is activated. For example, if the quality difference (Qneighbor –Qserv) goes above a given set threshold, the first apparatus 110 may determine that FBS is activated for the neighbor cell, and the first apparatus 110 may perform L3 measurements using FBS assumptions. For example, if the network has configured the first apparatus 110 to use multiple-receiver (or multiple-Rx or multi-Rx) beam sweeping, or if the first apparatus 110 is not configured with a CA configuration that does not allow multiple-Rx beam sweeping, the first apparatus 110 may use FBS.
[0080] Once the quality difference (Qneighbor –Qserv) gets below the given threshold, the first apparatus 110 may determine that FBS is deactivated for the neighbor cell, the first apparatus 110 may disable multiple-receiver beam sweeping on the neighboring cell to ensure no extra power consumption. The first apparatus 110 then may perform measurements without multi-Rx beam sweep.
[0081] In some example embodiments, the first apparatus 110 may apply FBS when the neighbor cell is hysteresis above serving cell (even if the serving cell has good quality) . In one example, the first apparatus 110 may have a good signal quality from the serving cell while the neighboring cell becomes threshold better than the serving cell. Then, an L3 measurement with a reduced beam sweeping factor, is in favor of network for providing higher throughput to the first apparatus 110. The FBS may be useful for performing faster measurements or performing measurements with the same delay, but with less measurement occasions. This may improve throughput since the first apparatus 110 is not subject to so many scheduling restrictions that are necessary when measuring all the SMTC occasions.
[0082] In some example embodiments, at least one set of thresholds for activating the multiple-receiver measurement mode for the at least one cell may be associated with the at least one cell. In an example, different thresholds may be configured for different neighbor cells. In this example, the procedure as described above may be independently performed by the first apparatus 110 for each possible neighbor cell.
[0083] In some example embodiments, the at least one set of thresholds may be associated with at least one measurement type such as inter-frequency measurements and intra-frequency measurements. For example, the same principles of L3 measurement with fast beam sweeping may be applied in an inter-frequency measurement scenario as well.
[0084] In some example embodiments, the at least one set of thresholds may be associated with at least one connection state of the first apparatus 110. For example, the first apparatus 110 may be in a connected state or mode and perform the measurements and cell detection based on the current 5G NR or future communication system i.e., 6G systems. In another example, the first apparatus 110 may be not limited to a connected mode but also to other states such as an idle state, an inactive state and active state.
[0085] In some example embodiments, the at least one set of thresholds may be associated with at least one beam sweeping factor. For example, multiple thresholds may be established, which may be associated with multiple BSFs. For different threshold values, different number of receiving chains may be introduced. The process for FBS activation may be influenced by the number of receiving chains, which may depend on the quality of the neighboring cell versus the serving cell. For example, as the cell quality difference between the neighbor cell and the serving cell increases, a lower beam sweeping factor or more receiving chains will be applied. This allows for a gradual relaxation of the beam sweep within a time domain.
[0086] An example process of FBS activation based on (Qneighbor –Qserv) difference will be discussed below with reference to FIG. 5. In this example, a UE 505 (as an example of the first apparatus 110) may communicate with the network via a serving cell 510 and a neighbor cell 515 which may be served by the second apparatus 120 or other apparatuses.
[0087] As shown in FIG. 5, at 520, the UE 505 may be in a radio resource control (RRC) connected mode. The UE 505 may be not limited to a connected mode but also to other UE states. At 522, the UE 505 may apply legacy beam sweeping with a higher BSF. At 524, the UE 505 may receive SSBs from the serving cell 510. At 526, the UE 505 may receive SSBs from the neighbor cell 515. The UE may perform the measurements and cell detection according to the legacy requirements.
[0088] At 528, a RRC configuration for enabling a multiple-receiver (or multiple-Rx) measurement mode (also called a multiple-Rx reception mode) may be transmitted to the UE 505 over the serving cell 510 based on the capabilities of the UE 505. For example, the RRC configuration may include a configuration allowing the UE 505 to apply the multiple-Rx measurement mode. At 530, as the multiple-Rx reception mode may be enabled by the UE 505, the UE 505 may start monitoring neighbor cells. At 532, the UE 505 may receive SSBs from the serving cell 510. At 534, the UE 505 may receive SSBs from the neighbor cell 515. The UE 505 may perform measurement on the serving and neighboring cells according to legacy requirements.
[0089] At 536, the UE 505 may determine the condition for FBS on the serving cell 510 versus the neighboring cell 515. For example, the UE may evaluate whether the condition for FBS on the neighboring cell 515 is fulfilled. At 538, the UE 505 may determine that the quality difference (Qneighbor –Qserv) is greater than a hysteresis threshold. At 540, the UE 505 may apply multiple-Rx fast beam sweeping measurements. At 542, the UE 505 may receive SSBs from the serving cell 510. At 544, the UE 505 may receive SSBs from the neighbor cell 515. The UE 505 may apply FBS for measurements on the neighbor cell 515. For example, If the neighboring cell 515 is in good condition (with threshold better quality than the serving cell 510) , the UE 505 may apply FBS on measurements of the neighboring cell 510. In some example embodiments, beam sweep related to measurements of the serving cell 510 may not be changed.
[0090] At 546, the UE 505 may determine that the quality difference (Qneighbor –Qserv) is less than the hysteresis threshold. At 548, the UE 505 may determine that the multiple-Rx beam sweeping measurement is not activated. At 550, the UE 505 may receive SSBs from the serving cell 510. At 552, the UE 505 may receive SSBs from the neighbor cell 515. For example, once the quality difference gets below the threshold, the UE 505 may disable multiple-Rx beam sweeping on the neighboring cell 515 to ensure no extra power consumption. The UE 505 then may perform measurements without multi-Rx beam sweep.
[0091] In some example embodiments, the UE 505 may be controlling everything by itself, but not configured by the network. In this case, the procedure is same, but entirely autonomous at the UE side.
