Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, and more particularly to a method, apparatus and communication device for beam measurement of cooperative cells. [Background technology]

[0002] In NR (New Radio, New Radio Technology or New Air Interface), beam-based transmission and reception may be used to ensure signal coverage, especially when the communication frequency band is in frequency range 2, due to fast attenuation of high frequency channels.

[0003] When a UE (User Equipment) moves to the edge of a serving cell, a situation may arise in which the performance of the serving cell is measured to be good on antenna panel panel #1 (panel #1) but the performance of a neighboring cell is measured to be good on panel #2 (panel #2), or the performance of the serving cell is measured to be good on beam #1 but the performance of a neighboring cell is measured to be good on beam #2, and beam #1 and beam #2 may correspond to the same antenna panel of the UE or to different antenna panels of the UE.

[0004] In this case, if the UE remains in the serving cell or switches to a neighboring cell, the throughput will not be optimal. This is because the UE may be located in an overlapping area of ​​the coverage of the two cells, which may result in a situation where the serving cell sometimes performs better and the neighboring cell sometimes performs better. In this situation, the optimal solution is for different cells to simultaneously transmit data to the UE based on beams, and for the beams to switch dynamically. This requires the UE to be able to measure the beams of the neighboring cells. Furthermore, when the UE switches to a neighboring cell, the UE must measure the beam performance of the neighboring cell in advance to ensure a fast switchover, so that the destination base station can quickly use a good beam to transmit data to the UE. However, currently, there is no method for measuring the beams of neighboring cells. Summary of the Invention

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. When reference is made to the drawings in the following description, the same numerals in different drawings represent the same or similar elements unless otherwise specified. The embodiments described in the following exemplary embodiments do not represent all embodiments that may be consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods that may be consistent with some aspects of the embodiments of the present disclosure, as detailed in the appended claims.

[0033] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise. The term "and / or," as used herein, should be understood to refer to the inclusion of any and all possible combinations of one or more associated listed items.

[0034] Although various pieces of information may be described in embodiments of the present disclosure using terms such as first, second, and third, it should be understood that such information is not limited by these terms. These terms are merely used to distinguish between pieces of information of the same type. For example, first information may be referred to as second information, and similarly, second information may be referred to as first information, without departing from the scope of embodiments of the present disclosure. Depending on the context, terms such as "if" used herein may be interpreted as "if..." or "when..." or "in response to a determination."

[0035]

[0023] The following detailed description of the embodiments of the present disclosure is provided in the drawings, in which examples of the embodiments are shown, and the same or similar elements are always represented by the same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative and are provided for the interpretation of the present disclosure, and are not to be construed as limitations on the present disclosure.

[0036] In NR, due to fast attenuation of high frequency channels, beam-based transmission and reception may be used to ensure signal coverage, especially when the communication frequency band is in frequency range 2. Currently, both the base station and the UE use a single panel to transmit and receive data.

[0037] If the base station has multiple TRPs (Transmission Reception Points) and each TRP has one or more transmission panels, or if the base station has only one TRP and the TRP has multiple transmission panels, the base station may use multiple panels (which may be from the same TRP or different TRPs) to transmit data to the same UE simultaneously. Similarly, if the UE has multiple panels, the UE may use multiple panels to transmit data to the base station.

[0038] However, when the UE moves to the edge of the serving cell, a situation may arise in which the performance of the serving cell is measured as good on panel #1, but the performance of the neighboring cell is measured as good on panel #2, or in which the performance of the serving cell is measured as good on beam #1, but the performance of the neighboring cell is measured as good on beam #2, and beam #1 and beam #2 may correspond to the same antenna panel of the UE or to different antenna panels of the UE.

[0039] In this case, if the UE remains in the serving cell or switches to a neighboring cell, the throughput will not be optimal. This is because the UE may be located in an overlapping area of ​​the coverage of the two cells, which may result in a situation where the serving cell sometimes performs better and the neighboring cell sometimes performs better. In this situation, the optimal method is for different cells to simultaneously transmit data to the UE based on beams, and the beams are dynamically switched, which requires the UE to be able to measure the beams of the neighboring cells. In addition, when the UE switches to a neighboring cell, in order to achieve fast switching, the UE also needs to measure the beam performance of the neighboring cell in advance, so that the destination base station can quickly use a good beam to transmit data to the UE.

[0040] In the related art, when a UE reports a beam measurement result of a serving cell, it directly reports the ID of the reference signal used to measure the beam of the serving cell and the corresponding measurement result, L1-RSRP (Layer 1-Reference Signal Receiving Power) and / or L1-SINR (Layer 1-Signal to Interference plus Noise Ratio). Because the transmission power of the serving cell is the same, the result measured by the UE may be directly fed back in beam measurement. However, when it is necessary to feed back the beam measurement result of a neighboring cell, if the transmission power of the neighboring cell is not the same as the transmission power of the serving cell, the method of directly feeding back the result measured by the UE may cause the feedback result to not directly reflect the path loss between the UE and the neighboring cell. Assuming that the beam is used for uplink transmission, the selected beam may not be the best beam. For example, if the transmission power of a neighboring cell is higher and the beam measurement result of the neighboring cell is better, but the path loss between the UE and the neighboring cell is actually greater than the path loss between the UE and the serving cell, if the beam of the neighboring cell is selected based on the beam measurement result, the beam performance of the neighboring cell will be inferior to that of the serving cell.

[0041] In response to the above problems, the present disclosure provides a method, apparatus, and communication device for beam measurement of cooperative cells.

[0042] 1 is a flowchart of a beam measurement method for cooperative cells provided by an embodiment of the present disclosure, which may be performed by a UE.

[0043] A UE may be a device that provides a user with voice and / or data connectivity, a handheld device with wireless connectivity, or another processing device connected to a wireless modem. The term UE may vary depending on the system. A wireless UE can communicate with one or more CNs (Core Networks) via a RAN (Radio Access Network). A wireless UE may be a mobile terminal device, such as a mobile phone (also called a "cellular" phone), or a computer with a mobile terminal device, such as a portable, pocket, handheld, computer-embedded, or vehicle-mounted mobile device, that exchanges voice and / or data with the radio access network.

[0044] For example, a UE may be a device such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiated Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), etc. A wireless UE may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, and is not limited to such devices in the embodiments of the present disclosure.

[0046] In the embodiments of the present disclosure, a cooperating cell is also referred to as a neighboring cell or a non-serving cell, i.e., a cell that has a different physical cell identity (PCI) from that of the serving cell.

[0047] In an embodiment of the present disclosure, the first transmission power of the cooperative cell may be the transmission power of a reference signal used for beam measurement of the cooperative cell.

According to a specific application scenario, each cell may further include multiple TRPs (Transmission Reception Points), and each TRP may include one or more antenna panels, or may be a device that communicates with wireless terminal devices via one or more sectors over the air interface in an access network, or may be otherwise called.

The beam measurement method for cooperative cells may be executed alone, or may be executed in combination with any embodiment or possible implementation of the embodiment of the present disclosure, or may be executed in combination with any technical solution in the related art.

[0099] As shown in FIG. 5, the beam measurement method for the cooperative cell may include the following steps. In step 501, receiving indication information sent by a network device, the indication information including a first transmission power of a cooperative cell.

[0100] In step 502, determine a beam measurement reference signal resource of a cooperative cell, and obtain a second beam measurement result of the cooperative cell based on the beam measurement reference signal resource of the cooperative cell.

[0101] In step 503, a first beam measurement result of the cooperative cell is obtained based on the first transmission power.

[0102] In step 504, beam measurement results are sent to the network device, where the beam measurement results include a first beam measurement result and / or a second beam measurement result, and the beam measurement results further include a third beam measurement result of the serving cell and / or a fourth beam measurement result of the serving cell.

[0103] In the embodiments of the present disclosure, steps 501 to 504 may be implemented using any of the modes according to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto and will not be described in detail.

[0104] In an embodiment of the present disclosure, the beam measurement results of the serving cell obtained by the UE performing beam measurements on the serving cell may include a third beam measurement result of the serving cell and / or a fourth beam measurement result of the serving cell.

[0105] In a possible implementation form of an embodiment of the present disclosure, the third beam measurement result may be a beam measurement result obtained by the UE performing a beam measurement based on the beam measurement reference signal resource of the serving cell, i.e., the UE may determine the beam measurement reference signal resource of the serving cell and perform a beam measurement based on the beam measurement reference signal resource of the serving cell to obtain the third beam measurement result of the serving cell.

[0106] The third beam measurement results may include at least one of L1-RSRP, L1-SINR.

[0107] In one example, the UE may receive reference signal resource configuration information transmitted by a network device, and determine a beam measurement reference signal resource of the serving cell based on the reference signal resource configuration information, thereby performing beam measurement based on the beam measurement reference signal resource of the serving cell to obtain a third beam measurement result of the serving cell.

[0108] In another example, the UE may determine the beam measurement reference signal resource of the serving cell by actively searching for a reference signal, and then perform beam measurement based on the beam measurement reference signal resource of the serving cell to obtain a third beam measurement result of the serving cell.

[0109] In a possible implementation of an embodiment of the present disclosure, the fourth beam measurement result may be obtained based on the third beam measurement result and the transmission power of the serving cell.

[0110] In a possible implementation form, the UE may receive transmission power information of the serving cell, for example, the UE may receive transmission power information of the serving cell transmitted by a network device, and obtain a fourth beam measurement result of the serving cell based on the third beam measurement result of the serving cell and the transmission power information of the serving cell.

[0111] As an example, the UE may determine the transmission power of the serving cell based on the received transmission power information of the serving cell, and subtract the transmission power of the serving cell from the third beam measurement result to obtain the fourth beam measurement result.

[0112] As an example, the third beam measurement result is described as being L1-RSRP, and assuming that the transmission power of the serving cell is P2, the fourth beam measurement result may be (L1-RSRP-P2), and as an example, the third beam measurement result is described as being L1-SINR, and assuming that the transmission power of the serving cell is P2, the fourth beam measurement result may be (L1-SINR-P2).

[0113] Optionally, the above beam measurement result reporting scheme may include at least one of periodic reporting, aperiodic reporting, and semi-static semi-persistent reporting.

That is, each beam in each group has a corresponding ID, which is referred to as a beam group ID in this disclosure.

[0124] Item 2 is PCI. That is, the beams of different groups are beams of different cells.

[0125] Item 3 is CORESETPoolIndex (Control Resource Set Pool Index). That is, beams in different groups have different CORESETPoolIndex. Optionally, different CORESETPoolIndex may correspond to different PCI.

[0126] Item 4 is the reference signal resource set ID. Item 5 is the reference signal resource ID. Item 6 is the TRP ID. The TRP may be a TRP of a network device. Item 7 is the antenna panel ID.

[0127] The above panel may be a panel of a network device, or the above panel may be a panel of a UE, and the present disclosure is not limited thereto.

[0128] In a possible implementation of an embodiment of the present disclosure, beams within a group are beams that can be received simultaneously by a UE, or beams between different groups are beams that can be received simultaneously by a UE.

[0129] In an embodiment of the present disclosure, the UE may report beam measurement results to a network device by at least one group.

[0136] Where possible, beam measurements will be reported by the group. In Scheme 1, beam measurement results are reported by at least one group. For example, beam measurement results of coordinated cells are one group, and beam measurement results of a serving cell are one group, and each group corresponds to one group ID, which may be the PCI or CORESETPoolIndex of a cell or the ID of a reference signal resource set corresponding to measurements of beams of different cells.

[0137] In Scheme 2, beam measurement results are reported by at least one group. For example, the beams received by panel #1 of the UE are one group, and the beams received by panel #2 of the UE are another group. That is, beams in different groups are beams that can be simultaneously received by the UE, and each group corresponds to one panel ID, or each group corresponds to one reference signal resource ID or reference signal resource set ID that has a corresponding relationship with a panel.

[0138] In Scheme 3, beam measurement results are reported by at least one group, and the beams in a group are beams that the UE can simultaneously receive. The beams that the UE simultaneously receives may be beams that the UE receives using one spatial filter or multiple spatial filters.

[0139] In some circumstances, beam measurements may be reported in a non-group manner.

[0144] In step 704, in response to the reporting condition being met, beam measurement results are sent to the network device, where the beam measurement results include the first beam measurement result and / or the second beam measurement result.

[0145] In the embodiments of the present disclosure, steps 701 to 704 may be implemented using any of the modes according to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto and will not be described in detail.

[0148] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0149] An embodiment of the present disclosure provides another beam measurement method for cooperative cells, and Fig. 8 is a flowchart of another beam measurement method for cooperative cells provided by an embodiment of the present disclosure. The beam measurement method for cooperative cells may be executed by a UE. The beam measurement method for cooperative cells may be executed alone, or may be executed in combination with any embodiment or possible implementation of the embodiment of the present disclosure, or may be executed in combination with any technical solution in the related art.

[0150] As shown in FIG. 8, the beam measurement method for the cooperative cell may include the following steps. In step 801, receiving indication information sent by a network device, the indication information including a first transmission power of a cooperative cell.

[0151] In step 802, determine a beam measurement reference signal resource of a cooperative cell, and obtain a second beam measurement result of the cooperative cell based on the beam measurement reference signal resource of the cooperative cell.

[0152] In step 803, a first beam measurement result of the cooperative cell is obtained based on the first transmit power.

[0154] In the embodiments of the present disclosure, steps 801 to 804 may be implemented using any of the modes according to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto and will not be described in detail.

[0155] In the embodiment of the present disclosure, the first threshold may be configured by the network device or may be negotiated by a protocol, and the present disclosure is not limited thereto.

[0156] In an embodiment of the present disclosure, after obtaining a beam measurement result of a cooperative cell, a UE may determine whether the beam measurement result of the cooperative cell is greater than a first threshold. If the beam measurement result of the cooperative cell is greater than the first threshold, it may determine that the reporting condition is met, and the UE may report the beam measurement result of the cooperative cell to a network device. If the beam measurement result of the cooperative cell is not greater than the first threshold, it may determine that the reporting condition is not met, and the UE may not report the beam measurement result of the cooperative cell to a network device. The beam measurement result of the cooperative cell obtained by the UE may include a first beam measurement result and / or a second beam measurement result.

[0157] As an example, the UE may use the first beam measurement result of the cooperative cell to determine whether the reporting condition is met, i.e., the UE may determine whether the first beam measurement result of the cooperative cell is greater than a first threshold, and if the first beam measurement result of the cooperative cell is greater than the first threshold, it may determine that the reporting condition is met, and the UE may report the first beam measurement result and / or the second beam measurement result of the cooperative cell to the network device.

[0158] As another example, the UE may use the second beam measurement result of the cooperative cell to determine whether the reporting condition is met, i.e., the UE may determine whether the second beam measurement result of the cooperative cell is greater than a first threshold, and if the second beam measurement result of the cooperative cell is greater than the first threshold, it may determine that the reporting condition is met, and the UE may report the first beam measurement result and / or the second beam measurement result of the cooperative cell to the network device.

[0159] In the beam measurement method for a cooperative cell according to an embodiment of the present disclosure, a UE receives instruction information sent by a network device, the instruction information including a first transmission power of the cooperative cell, measures a beam for the cooperative cell, and obtains a first beam measurement result for the cooperative cell based on the first transmission power, thereby enabling the UE to perform beam measurement for the cooperative cell and obtain the beam measurement result for the cooperative cell, and the UE determining the beam measurement result for the cooperative cell from the transmission power of the cooperative cell can ensure the accuracy and timeliness of the beam measurement result.

[0160] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0161] An embodiment of the present disclosure provides another beam measurement method for cooperative cells, and Fig. 9 is a flowchart of another beam measurement method for cooperative cells provided by an embodiment of the present disclosure. The beam measurement method for cooperative cells may be executed by a UE. The beam measurement method for cooperative cells may be executed alone, or may be executed in combination with any embodiment or possible implementation of the embodiment of the present disclosure, or may be executed in combination with any technical solution according to the related art.

[0162] As shown in FIG. 9, the beam measurement method for the cooperative cell may include the following steps. In step 901, receive indication information sent by a network device, where the indication information includes a first transmission power of a cooperative cell.

[0163] In step 902, determine a beam measurement reference signal resource of a cooperative cell, and obtain a second beam measurement result of the cooperative cell based on the beam measurement reference signal resource of the cooperative cell.

[0164] In step 903, a first beam measurement result of the cooperative cell is obtained based on the first transmit power.

[0165] In step 904, in response to the reporting condition being met, the beam measurement result of the cooperative cell is sent to the network device, and the reporting condition is that the beam measurement result of the cooperative cell and the beam measurement result of the serving cell are sorted in order from strongest to weakest, and the beam measurement result of the cooperative cell is one of the top N beam measurement results.

[0166] N is a positive integer. Optionally, N may be the maximum number of beams that the UE can report in one beam report.

[0167] The beam measurement results of the cooperative cells may include a first beam measurement result and / or a second beam measurement result.

[0168] The beam measurement results of the serving cell may include a third beam measurement result and / or a fourth beam measurement result.

[0169] In the embodiments of the present disclosure, steps 901 to 904 may be implemented using any of the modes according to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto and will not be described in detail.

[0170] In an embodiment of the present disclosure, after obtaining the beam measurement result of the cooperative cell, the UE may sort the beam measurement result of the cooperative cell and the beam measurement result of the serving cell in order from strongest to weakest to obtain the sorted result, and determine whether the beam measurement of the cooperative cell is among the top N beam measurement results in the sorted result. If the beam measurement result of the cooperative cell is among the top N beam measurement results in the sorted result, the UE may determine that the reporting condition is met and may send the beam measurement result of the cooperative cell to the network device. If the beam measurement result of the cooperative cell is not among the top N beam measurement results in the sorted result, the UE may determine that the reporting condition is not met and may not report the beam measurement result of the cooperative cell to the network device.

[0171] For example, the UE may use the first beam measurement result of the cooperative cell to determine whether the reporting condition is met. That is, the UE may sort the first beam measurement result of the cooperative cell and the beam measurement result of the serving cell in order from strongest to weakest to obtain a sorted result, and determine whether the first beam measurement result of the cooperative cell is among the top N beam measurement results in the sorted result. If the first beam measurement result of the cooperative cell is among the top N beam measurement results in the sorted result, the UE may determine that the reporting condition is met, and may report the first beam measurement result and / or the second beam measurement result of the cooperative cell to the network device. The beam measurement result of the serving cell may include the third beam measurement result and / or the fourth beam measurement result.

[0172] As another example, the UE may use the second beam measurement result of the coordinated cell to determine whether the reporting condition is met. That is, the UE may sort the second beam measurement result of the coordinated cell and the beam measurement result of the serving cell in order from strongest to weakest to obtain a sorted result, and determine whether the second beam measurement result of the coordinated cell is among the top N beam measurement results in the sorted result. If the second beam measurement result of the coordinated cell is among the top N beam measurement results in the sorted result, the UE may determine that the reporting condition is met, and may report the first beam measurement result and / or the second beam measurement result of the coordinated cell to the network device. The beam measurement result of the serving cell may include the third beam measurement result and / or the fourth beam measurement result.

[0173] In the beam measurement method for a cooperative cell according to an embodiment of the present disclosure, a UE receives instruction information sent by a network device, the instruction information including a first transmission power of the cooperative cell, measures a beam for the cooperative cell, and obtains a first beam measurement result for the cooperative cell based on the first transmission power, thereby enabling the UE to perform beam measurement for the cooperative cell and obtain the beam measurement result for the cooperative cell, and the UE determining the beam measurement result for the cooperative cell from the transmission power of the cooperative cell can ensure the accuracy and timeliness of the beam measurement result.

[0174] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0175] In any embodiment of the present disclosure, the beam measurement results may include at least one of the following items: Item 1 is L1-RSRP. The L1-RSRP may be the L1-RSRP of the cooperating cell and / or the serving cell, i.e., the second beam measurement result and / or the third beam measurement result in the above embodiment.

[0176] Item 2 is L1-SINR. The L1-SINR may be the L1-SINR of the cooperating cell and / or the serving cell, i.e., the second beam measurement result and / or the third beam measurement result in the above embodiment.

[0177] Item 3 is a correction value based on the first transmission power of the L1-RSRP cooperative cell. For example, the correction value may be a value obtained by subtracting the first transmission power from the L1-RSRP of the cooperative cell, that is, the correction value may be the first beam measurement result.

[0178] Item 4 is a correction value based on the first transmission power of the coordinated cell for L1-SINR. For example, the correction value may be a value obtained by subtracting the first transmission power from the L1-SINR of the cooperative cell, that is, the correction value may be a first beam measurement result.

[0179] Item 5 is a correction value based on the transmission power of the serving cell of L1-RSRP. For example, the correction value may be a value obtained by subtracting the transmission power of the serving cell from the L1-RSRP of the serving cell, that is, the correction value may be a fourth beam measurement result.

[0180] Item 6 is a correction value based on the transmission power of the serving cell for L1-SINR. For example, the correction value may be a value obtained by subtracting the transmission power of the serving cell from the L1-SINR of the serving cell, that is, the correction value may be a fourth beam measurement result.

[0181] Item 7 is a correction value based on the UE's uplink transmission power of L1-RSRP. For example, the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the L1-RSRP of the cooperative cell, i.e., the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the second beam measurement result. In another example, the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the L1-RSRP of the serving cell, i.e., the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the third beam measurement result.

[0182] In addition, considering the influence of the MPE (Maximum Permissible Exposure) corresponding to the UE, i.e., because the UE's irradiation to the human body is large, the first transmission power is also related to the MPE, for example, the first transmission power may be the uplink transmission power of the UE's antenna panel, and in this case, the correction value of item 7 may be the first beam measurement result and / or the fourth beam measurement result.

[0183] Item 8 is a correction value of L1-SINR based on the UE's uplink transmission power.

[0184] For example, the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the L1-SINR of the cooperative cell, i.e., the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the second beam measurement result. In another example, the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the L1-SINR of the serving cell, i.e., the correction value may be a value obtained by subtracting the uplink transmit power of the UE's antenna panel from the third beam measurement result.

[0185] Similarly, if the first transmission power is the uplink transmission power of the UE's antenna panel, the correction value in item 8 may be the first beam measurement result and / or the fourth beam measurement result.

[0186] An embodiment of the present disclosure provides another method for beam measurement of cooperative cells, and FIG. 10 is a flowchart of the method for beam measurement of cooperative cells provided by the embodiment of the present disclosure. The method for beam measurement of cooperative cells may be executed by a UE. The method for beam measurement of cooperative cells may be executed independently, or may be executed in combination with any embodiment or possible implementation of the embodiment of the present disclosure, or may be executed in combination with any technical solution according to the related art.

[0187] As shown in FIG. 10, the beam measurement method for the cooperative cell may include the following steps. In step 1001, receive indication information sent by a network device, where the indication information includes a first transmission power of a cooperative cell.

[0188] In step 1002, determine a beam measurement reference signal resource of a cooperative cell, and obtain a second beam measurement result of the cooperative cell based on the beam measurement reference signal resource of the cooperative cell.

[0189] In step 1003, a first beam measurement result of the cooperative cell is obtained based on the first transmission power.

[0190] In step 1004, in response to the reporting condition being met, the beam measurement results of the cooperative cells are sent to the network device, and the reporting condition is to sort the beam measurement results of the cooperative cells in order from strongest to weakest and report the beam measurement results of the cooperative cells with the top M beam measurement results.

[0191] M is a positive integer. Optionally, M may be a positive integer less than or equal to N, where N may be the maximum number of beams that the UE can report in one beam report.

[0192] The beam measurement results of the cooperative cells include a first beam measurement result and / or a second beam measurement result.

[0193] In the embodiments of the present disclosure, steps 1001 to 1004 may be implemented using any of the modes according to the embodiments of the present disclosure, and the embodiments of the present disclosure are not limited thereto and will not be described in detail.

[0194] In an embodiment of the present disclosure, after obtaining the beam measurement results of the cooperative cells, the UE may sort the beam measurement results of the cooperative cells in order from strongest to weakest, and transmit the beam measurement results of the top M cooperative cells in the sorted results to the network device.

[0195] As an example, the UE may sort the first beam measurement results of the cooperative cells in order from strongest to weakest beam measurement results to obtain sorted results, screen the sorted results to obtain cooperative cells corresponding to the top M first beam measurement results, and report the first beam measurement results and / or second beam measurement results of the cooperative cells obtained by screening to the network device.

[0196] As another example, the UE may sort the second beam measurement results of the cooperative cells in order from strongest to weakest beam measurement results to obtain sorted results, screen the sorted results to obtain cooperative cells corresponding to the top M second beam measurement results, and report the first beam measurement results and / or second beam measurement results of the cooperative cells obtained by screening to the network device.

[0197] In the beam measurement method for a cooperative cell according to an embodiment of the present disclosure, a UE receives instruction information sent by a network device, the instruction information including a first transmission power of the cooperative cell, measures a beam for the cooperative cell, and obtains a first beam measurement result for the cooperative cell based on the first transmission power, thereby enabling the UE to perform beam measurement for the cooperative cell and obtain the beam measurement result for the cooperative cell, and the UE determining the beam measurement result for the cooperative cell from the transmission power of the cooperative cell can ensure the accuracy and timeliness of the beam measurement result.

[0198] It should be noted that the above possible implementation forms may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0199] In any embodiment of the present disclosure, the UE may determine which cooperating cell's beam measurement results to report based on at least one of the following, or may determine whether the beam measurement results of a particular cooperating cell meet the reporting conditions: The beam measurement results of the cooperative cells may include L1-RSRP and / or L1-SINR, i.e., second beam measurement results.

[0200] The beam measurement result of the cooperative cell may further include a first beam measurement result determined based on the second beam measurement result and a first transmission power of the cooperative cell, where the first transmission power of the cooperative cell is the transmission power of a reference signal used for the beam measurement of the cooperative cell.

[0201] The first transmission power may be a transmission power value of the cooperative cell.

[0202] In a possible implementation, the transmission power value of the cooperative cell may be the transmission power of an SSB, and the PCI corresponding to the SSB is the PCI of the cooperative cell.

[0203] In one example, the reporting condition for the beam measurement result of the cooperative cell may be that the beam measurement result of the cooperative cell is greater than a first threshold. In this case, the UE may compare the beam measurement result of the cooperative cell with the threshold. For example, if the first transmit power of the cooperative cell is P1 and the power of the serving cell is P2, the UE may subtract P1 from the beam measurement result of the cooperative cell (i.e., the second beam measurement result) to obtain a value (i.e., the first beam measurement result) and compare it with the threshold. If the first beam measurement result is greater than the threshold, the UE may determine that the reporting condition is met and may report the first beam measurement result corresponding to the cooperative cell.

[0204] Similarly, the value obtained by subtracting P2 from the beam measurement result of the serving cell (ie, the third beam measurement result) (ie, the fourth beam measurement result) may be compared with a threshold.

[0205] In another example, the reporting condition for the beam measurement results of the cooperative cells may be that the beam measurement results of the cooperative cells are the top N beam measurement results obtained by sorting all beam measurement results in ascending order. In this case, the UE may sort the beam measurement results of all cells, for example, the fourth beam measurement result of the serving cell and the first beam measurement result of the cooperative cells, in order of beam measurement results from strongest to weakest, and report the beam measurement results of the top N cooperative cells to the network device.

[0206] In another possible implementation, the transmit power value of the cooperative cell may be the transmit power of the CSI-RS, and further, the RS corresponding to QCL Type D of the CSI-RS is an SSB, and the PCI corresponding to the SSB is the PCI of the cooperative cell.

[0207] If the transmission power of CSI-RS is not the same as the transmission power of SSB, the above two examples can be used to determine whether the beam measurement results of the cooperative cell meet the reporting conditions, i.e., the transmission power of SSB in the above two examples can be replaced with the transmission power of CSI-RS.If the transmission power of CSI-RS is the same as the transmission power of SSB, the method of determining whether the beam measurement results of the cooperative cell meet the reporting conditions is the same as the above two examples.

[0208] The first transmit power may be the difference between the transmit power of the cooperating cell and the transmit power of the serving cell.

[0209] In one example, the reporting condition for the beam measurement result of the cooperative cell may be that the beam measurement result of the cooperative cell is greater than a threshold. In this case, the UE may determine the beam measurement result of the cooperative cell based on the above example (e.g., the first beam measurement result or the second beam measurement result). If the transmit power of the cooperative cell is higher than the transmit power of the serving cell by an offset, the UE may subtract an offset from the beam measurement result of the beam of the cooperative cell and then compare it with a threshold. If the beam measurement result after subtracting the offset is greater than the threshold, the UE may determine that the reporting condition is met and report the beam measurement result corresponding to the cooperative cell.

[0210] In another example, the reporting condition for the beam measurement result of the coordinated cell may be a step in which the beam measurement result of the coordinated cell is the top N beam measurement result among the sorted results obtained by sorting all beam measurement results in ascending order. Assuming that the transmit power of the coordinated cell is higher than that of the serving cell by an offset, the UE may subtract the offset from the beam measurement result of the coordinated cell (e.g., the first beam measurement result or the second beam measurement result), and sort the beam measurement result after subtracting the offset and the beam measurement result of the serving cell in order from strongest to weakest beam measurement result, thereby reporting the top N beam measurement results of the coordinated cells to the network device.

[0211] In any embodiment of the present disclosure, considering the influence of the MPE corresponding to the UE, that is, the irradiation of the UE to the human body is large, it is necessary to reduce the transmission power of the UE.

[0212] In one example, the reporting condition for the beam measurement result of the cooperative cell may be a step in which the beam measurement result of the cooperative cell is higher than a threshold. For example, the transmit power of the UE corresponding to the beam of the cooperative cell needs to be reduced by one offset. In this case, the UE may subtract one offset from the beam measurement result of the cooperative cell (e.g., may be the first beam measurement result or the second beam measurement result) and then compare it with the threshold. If the beam measurement result after subtracting the offset is greater than the threshold, the UE may determine that the reporting condition is met and report the beam measurement result corresponding to the cooperative cell.

[0213] In another example, the reporting condition for the beam measurement result of the cooperative cell may be that the beam measurement result of the cooperative cell is the top N beam measurement result among the sorted results obtained by sorting all beam measurement results in ascending order. For example, the transmit power of the UE corresponding to the beam of the cooperative cell needs to be reduced by one offset. In this case, the UE may subtract one offset from the beam measurement result of the cooperative cell (e.g., the first beam measurement result or the second beam measurement result), and sort the beam measurement result after subtracting the offset and the beam measurement result of the serving cell in order from strongest to weakest beam measurement result, thereby reporting the top N beam measurement results of the cooperative cells to the network device.

[0214] In any embodiment of the present disclosure, the beam measurement results of the coordinated cells reported by the UE may include at least one of the following: 1. Directly measured L1-RSRP and / or L1-SINR of cooperative cells. 2. The result after applying a correction value to the directly measured L1-RSRP and / or L1-SINR, where the correction value is determined based on at least one of the following: 1) Cooperative cell transmission power For example, the beam measurement result of the cooperative cell is fed back as L1-RSRP minus the transmit power of the cooperative cell (i.e., the first beam measurement result is fed back), and / or the beam measurement result of the serving cell is fed back as L1-RSRP minus the transmit power of the serving cell (i.e., the fourth beam measurement result is fed back).

[0215] 2) Difference between the transmit power of the cooperative cell and the transmit power of the serving cell For example, the beam measurement results of the cooperative cell are fed back by subtracting the difference in transmission power between the cooperative cell and the serving cell from the L1-RSRP.

[0216] 3) Influence of MPE on different panels Considering the influence of P-MPR (Power Management Maximum Power Reduction) of different panels and virtual PHR (Power Headroom), for example, the beam measurement results of the coordinated cell are fed back by subtracting the transmission power value that the UE should reduce from the L1-RSRP.

[0217] In the present disclosure, when a UE reports beam measurement results of a cooperative cell, the accuracy and timeliness of the beam measurement results of the cooperative cell can be ensured and the performance of the UE can be improved by determining whether to report the beam measurement results of the cooperative cell and which cooperative cell's beam measurement results to report based on the transmission power of the cooperative cell.
