TECHNICAL FIELD

[0002] In a wireless communication system, a network device and a terminal device determine an optimal beam through a beam training process, so as to use the optimal beam to improve the reliability of signal transmission. In the process of beam measurement and reporting of the terminal device, each transmission beam corresponds to a reference signal. After the terminal device measures a plurality of reference signals, the terminal device reports the identification of the reference signal corresponding to at least one optimal beam. In the existing protocol, the network device has similar channel conditions between each antenna port in the antenna port array. Therefore, the network device and the terminal device only need to train the optimal beam of 1 or 2 antenna ports, and can obtain the optimal beam of all antenna ports.

[0003] With the increasing number of antenna ports of the network device, the size of the antenna port array will become larger. Therefore, only part of the antenna ports in the antenna port array have similar channel conditions, thereby causing a spatial non-stationary phenomenon.

[0004] However, under the spatial non-stationary condition, the existing beam management process cannot monitor the optimal beam of multiple ports in the antenna port array. SUMMARY

[0046] The communication systems applicable to the embodiments of this application include, but are not limited to, Long Term Evolution (LTE) systems, 5th-generation (5G) systems, New Radio (NR) systems, and future evolution systems or multiple converged communication systems. The 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solutions of this application are also applicable to different network architectures, including but not limited to relay network architectures, dual-connectivity architectures, and vehicle-to-everything (V2X) communication architectures.

[0047] This application primarily relates to communication between terminal devices and network devices. Specifically:

[0048] The network device in this application embodiment can also be called an access network device, for example, it can be a base station (BS) (also called a base station device). A network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in second-generation (2G) networks, the equipment providing base station functionality includes base transceiver stations (BTS); in third-generation (3G) networks, it includes nodes (NodeB); in fourth-generation (4G) networks, it includes evolved nodes (eNB); in wireless local area networks (WLANs), it includes access points (APs); and in NR, it includes next-generation node base stations (gNBs) and further evolved nodes (ng-eNBs). gNBs communicate with terminal devices using NR technology, while ng-eNBs communicate with terminal devices using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network devices in this application embodiment also include devices that provide base station functions in future new communication systems.

[0049] In this application, "terminal equipment" can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication equipment, user agents, or user devices. Terminal equipment can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application does not limit the scope of these terms. Terminal equipment can also be referred to as User Equipment (UE), terminal, etc.

[0050] As described in the background section, under spatially non-stationary conditions, existing beam management processes are unable to monitor the optimal beam across multiple ports in an antenna port array.

[0051] Specifically, under spatially non-stationary conditions, the antenna port array can be divided into one or more visible regions. Each visible region contains adjacent antenna ports and has similar channel conditions. The visible region can represent the area visible to the terminal device relative to the antenna array. For example, network devices can use reference signals to determine the visible region of the terminal device on the antenna panel within the transmission path to the terminal device. Under spatially non-stationary conditions, the number of antenna ports in the visible region is variable, and different visible regions have different optimal beams.

[0052] Specifically, such as Figure 1 As shown, UE1 is only visible in the visible area 1 of the array, UE2 is only visible in visible areas 1 and 2, UE3 is only visible in visible area 2, and UE4 is only visible in visible areas 2 and 3.

[0053] Therefore, how to measure and report the visible area under non-stationary spatial conditions is a problem that needs to be solved.

[0054] In this embodiment, the terminal device indicates the antenna port and its corresponding beam to the network device through the measurement results of the reference signal, thereby realizing the measurement and reporting of multiple ports and their corresponding optimal beams, assisting the network device in making switching decisions, and providing better communication services for the terminal device.

[0055] Furthermore, by instructing N first antenna port groups and / or one or more second antenna port groups through measurement reports, the terminal equipment can measure and report the visible area.

[0056] First, some of the terms used in the embodiments of this application will be introduced to facilitate understanding by those skilled in the art.

[0057] The antenna port array referred to in the embodiments of this application may also be called an antenna assembly, beam set, antenna array, antenna panel, antenna panel group, antenna panel collection, logical entity, entity, or antenna entity, etc. The size of the antenna port array refers to the number of antenna ports in the one-dimensional or two-dimensional antenna port array.

[0058] The antenna port group referred to in the embodiments of this application may also be called an antenna group, an antenna port set, etc.

[0059] In this application, the term "antenna port subarray" refers to an antenna port array divided according to a certain size. An antenna port subarray can be a portion of an antenna port array. Antenna port subarrays can also be called antenna subarrays, antenna port arrays, beamsets, etc. The size of an antenna port subarray refers to the number of antenna ports in the one-dimensional or two-dimensional antenna port subarray.

[0060] For example, the size of an antenna port array is (M, N), indicating that the number of ports in one direction is M and the number of ports in the other direction is N; the size of an antenna port subarray is (X, Y), indicating that the number of ports in one direction is X and the number of ports in the other direction is Y, where X is less than M, Y is less than N, and M and N are positive integers. One direction can be horizontal and the other vertical; or one direction can be vertical and the other horizontal.

[0061] For example, the relationship between antenna port arrays, antenna port groups, and antenna port subarrays can be that an antenna port array includes at least one antenna port group, and each antenna port group may include at least one antenna port subarray.

[0062] In this embodiment, the reference signal can be a downlink reference signal, specifically a Channel State Information Reference Signal (CSI-RS), a Cell-specific Reference Signal (CRS), or other downlink reference signals used for CSI measurement.

[0063] In this embodiment, the antenna port array is a very large-scale antenna array with a large number of antenna ports. The range of the near-field region of the antenna port array is also gradually becoming significant, and the terminal device can perform near-field communication with the network device within this region.

[0064] The embodiments of this application are mainly used in near-field communication scenarios. The main application scenarios of near-field communication include, but are not limited to: near-field multi-terminal device communication, near-field positioning and sensing (distance-aware channels), near-field wireless power transfer, near-field integrated sensing design, physical layer security, etc.

[0065] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0066] See Figure 2 The method provided in this application specifically includes the following steps:

[0067] Step 201: The network device transmits a reference signal through each of the at least one antenna port subarray. Correspondingly, the terminal device receives the reference signal from each of the at least one antenna port subarray.

[0068] In this embodiment, the terminal device can measure the reference signals by receiving reference signals from each of the at least one antenna port subarray, thereby obtaining measurement results for the reference signals. These measurement results represent the signal reception quality of the reference signals. This allows for the measurement of each antenna port subarray within the at least one antenna port subarray, obtaining measurement results for the antenna port subarray, which in turn represent the signal reception quality of the antenna port subarray.

[0069] Wherein, at least M antenna port subarrays in at least one antenna port subarray are antenna port subarrays included in at least one first antenna port group, and each first antenna port group includes one or more antenna port subarrays. That is, at least one antenna subarray includes at least one first antenna port group. For example, the at least one first antenna port group may be composed of M antenna port subarrays. Furthermore, in addition to including at least one first antenna port group, at least one antenna subarray may also include other antenna subarrays besides the at least one first antenna port group.

[0070] Furthermore, at least one first antenna port group is an antenna port group that can be used for data transmission. That is, at least one first antenna port group can provide communication services for the terminal device.

[0071] For example, if a network device sends downlink data to a terminal device and receives uplink data through each antenna port subarray in antenna port group 1, antenna port group 2, antenna port group 3, and antenna port group 4, then antenna port group 1, antenna port group 2, antenna port group 3, and antenna port group 4 constitute the first antenna port group.

[0072] In this embodiment, the terminal device can measure the first antenna port group that provides communication services by measuring the reference signals from the M antenna port subarrays, thereby obtaining the signal reception quality of the first antenna port group.

[0073] Specifically, the measurement results of the reference signal may include at least one of the following:

[0074] Reference Signal Receiving Power (RSRP), Signal-to-Interference & Noise Ratio (SINR), Signal-to-Noise Ratio (SNR), Signal-to-Interference Ratio (SIR), Reference Signal Receiving Quality (RSRQ), Channel Quality Indicator (CQI), Received Signal Strength Indication (RSSI), Carrier-to-Interference Ratio (CIR), Transmission Delay, and Reception Time, etc.

[0075] Step 202: The terminal device sends a measurement report based on the measurement results of the reference signals transmitted by one or more antenna port subarrays in at least one antenna port subarray. Accordingly, the network device receives the measurement report.

[0076] In this embodiment, the measurement report indicates at least N first antenna port groups in at least one first antenna port group; and / or, the measurement report indicates one or more second antenna port groups, each second antenna port group including one or more antenna port subarrays in at least one antenna port subarray.

[0077] In this embodiment, the terminal device indicates the antenna ports and their corresponding beams to the network device based on the measurement results of the reference signal. This enables the measurement and reporting of multiple ports and their corresponding optimal beams, assisting the network device in making handover decisions to provide the terminal device with better communication services. For example, the measurement report indicates N first antenna port groups. In this case, the terminal device only indicates the antenna ports and their corresponding beams in the antenna port groups currently providing communication services to the network device.

[0078] For example, the measurement report indicates one or more second antenna port groups. In this case, the terminal device indicates to the network device the other antenna ports in the antenna port subarray besides the individual antenna ports in the N first antenna port groups and their corresponding beams.

[0079] For example, the measurement report indicates N first antenna port groups and one or more second antenna port groups. In this case, the terminal device can simultaneously indicate the antenna ports and their corresponding beams in the antenna port groups currently providing communication services, as well as the antenna ports and their corresponding beams in other antenna port subarrays.

[0080] It should be noted that the sequence number of each step in this embodiment does not represent a limitation on the execution order of each step.

[0081] It is understood that, in specific implementations, the communication method can be implemented using a software program, which runs in a processor integrated within the chip or chip module. The method can also be implemented using a combination of software and hardware; this application does not impose any restrictions.

[0082] The following descriptions illustrate different triggering conditions in the measurement reports, along with various implementation examples.

[0083] Example 1: If the terminal device detects that the measurement result of the reference signal transmitted by one or more antenna port subarrays in each of the N first antenna port groups is less than a first threshold, it sends a measurement report.

[0084] In this embodiment, the trigger condition for the measurement report is that the measurement result of the reference signal transmitted by one or more antenna port subarrays included in each of the N first antenna port groups is less than a first threshold. In other words, the terminal device determines one or more antenna port subarrays whose reference signal measurement result is less than the first threshold, and defines the first antenna port group in which the one or more antenna port subarrays are located as the N first antenna port groups.

[0085] In this embodiment, if the measurement result of the reference signal transmitted by the antenna port subarray is less than the first threshold, it means that the signal reception quality of the antenna port subarray is poor. In other words, the terminal device reports a measurement report when the first antenna port group available for data transmission deteriorates, in order to assist the network device in making a handover decision.

[0086] In this embodiment, the measurement report includes at least one of the following:

[0087] The identifiers of the N first antenna port groups; or...

[0088] The identifier of the antenna port subarray whose measured value of the transmitted reference signal is less than a first threshold in the N first antenna port groups; or,

[0089] The identifier of the reference signal whose measurement result is less than a first threshold among the reference signals transmitted by the antenna port subarrays in the N first antenna port groups.

[0090] Since the reference signal is transmitted through the antenna port subarray, the identifier of the reference signal can indirectly indicate the antenna port subarray.

[0091] For example, if N=4, the terminal device measures the reference signal from the antenna port subarrays in the eight first antenna port groups (groups 1 to 8) and finds that the measurement result of the reference signal transmitted by at least one antenna port subarray in each of the first antenna port groups 1 to 4 is less than the first threshold. In this case, the terminal device can report the identifiers of the first antenna port groups 1 to 4, namely 1, 2, 3 and 4.

[0092] For example, each first antenna port group includes four antenna port subarrays. The measurement results of reference signal 1 transmitted by antenna port subarray 1 and reference signal 2 transmitted by antenna port subarray 2 in first antenna port group 1 are less than a first threshold; the measurement result of reference signal 5 transmitted by antenna port subarray 5 in first antenna port group 2 is less than the first threshold; the measurement result of reference signal 10 transmitted by antenna port subarray 10 in first antenna port group 3 is less than the first threshold; and the measurement result of reference signal 15 transmitted by antenna port subarray 15 in first antenna port group 4 is less than the first threshold. In this case, the terminal device can report the identifiers of antenna port subarray 1, antenna port subarray 2, antenna port subarray 5, antenna port subarray 10, and antenna port subarray 15.

[0093] For example, the terminal device can also report the identifiers of reference signal 1, reference signal 2, reference signal 5, reference signal 10, and reference signal 15.

[0094] It should be noted that the specific value of the first threshold can be specified by the communication standard protocol or configured by the network device; this application does not impose any restrictions on this.

[0095] Example 2: The terminal device determines one or more second antenna port groups based on the measurement results of reference signals transmitted by one or more antenna port subarrays in at least one antenna port subarray, and sends a measurement report.

[0096] In this embodiment, the triggering condition for the measurement report is that the terminal device determines one or more second antenna port groups based on the measurement results of reference signals transmitted by one or more antenna port subarrays in at least one antenna port subarray.

[0097] Please refer to the details. Figure 3 , Figure 3 The flowchart of a communication method is shown.

[0098] In step 301, the terminal device receives a reference signal from each of the at least one antenna port subarray.

[0099] In step 302, the terminal device determines one or more second antenna port groups based on the measurement results of reference signals transmitted by one or more antenna port subarrays in at least one antenna port subarray.

[0100] In this embodiment, the terminal device can determine the antenna port group with better signal reception quality, i.e., one or more second antenna port groups, based on the measurement results of the reference signal transmitted by the antenna port subarray. In other words, the terminal device reports a measurement report when it discovers an antenna port group with better reception quality to assist the network device in making handover decisions.

[0101] In one specific implementation, among the reference signals transmitted by each antenna port subarray of the second antenna port group, there is a reference signal whose measurement result is greater than or equal to a second threshold.

[0102] In this embodiment, the terminal device determines the second antenna port group with better reception quality by comparing the measurement result of the reference signal with an absolute value (i.e., a second threshold). In other words, the terminal device determines that the measurement result of the reference signal is greater than or equal to the second threshold antenna port subarray, and determines one or more second antenna port groups based on the antenna port subarray.

[0103] In another specific embodiment, among the reference signals transmitted by each antenna port subarray of the second antenna port group, there is a reference signal whose measurement result is greater than the maximum or minimum value among the measurement results of the reference signals transmitted by the antenna port subarray of the first antenna port group.

[0104] In this embodiment, the terminal device determines the second antenna port group with better reception quality by comparing the measurement result of the reference signal with a relative value (that is, the measurement result of the reference signal transmitted by the antenna port subarray included in the first antenna port group).

[0105] In a non-limiting embodiment, when determining the second antenna port group, the terminal device may determine the second antenna port group according to at least one of the following conditions, that is, the second antenna port group needs to satisfy at least one of the following conditions 1-4.

[0106] Condition 1: The channel parameters of multiple antenna ports in each second antenna port group are the same, and the channel parameters of the antenna ports are determined based on the measurement results of at least one reference signal.

[0107] Condition 2: The multiple antenna ports in each second antenna port group are adjacent in the antenna port array.

[0108] Condition 3: The outer contour of the array formed by the multiple antenna ports in each second antenna port group is rectangular.

[0109] Condition 4: The number of antenna ports in each second antenna port group can be the same or different.

[0110] In condition 1, the channel parameters of the antenna port can be at least one of the following: the received power of the reference signal transmitted by the antenna port, the average time delay, the frequency offset, and the Doppler offset. The channel parameters of the antenna port can characterize the channel quality of the antenna port. By making the channel parameters identical among multiple antenna ports in each antenna port group, spatial stationarity can be satisfied among multiple antenna ports in each antenna port group.

[0111] In other words, when determining the second antenna port group, the terminal device considers grouping multiple ports with the same channel parameters into the same antenna port group.

[0112] For example, the channel parameter is the received power of the reference signal. The received power of the reference signal transmitted by antenna port 1 is RSRP1, and the received power of the reference signal transmitted by antenna port 2 is RSRP2. If the values ​​of RSRP1 and RSRP2 are the same, or the difference between the values ​​of RSRP1 and RSRP2 is less than a preset threshold, it means that the channel parameters of antenna port 1 and antenna port 2 are the same.

[0113] For example, when the channel parameter is the received power of the reference signal, the channel parameter can be obtained directly from the measurement results of the reference signal.

[0114] For example, when the channel parameter is the average delay, the channel parameter can be calculated from the transmission delay of the reference signal in the measurement results of the reference signal. For instance, if antenna port 1 transmits the same reference signal four times at different times, and the terminal device measures the reference signal four times to obtain four measurement results, then the average delay of antenna port 1 is the average of the four transmission delays in the four measurement results.

[0115] In condition 2, since the probability of spatial stability between adjacent antenna ports is relatively high, the terminal device considers dividing multiple adjacent antenna ports in the antenna port array into the same antenna port group when determining the second antenna port group.

[0116] Specifically, each antenna port has a position in the antenna port array. Two antenna ports are adjacent in the antenna port array if they are adjacent in the row or column direction of the array. Please refer to [link / reference] for details. Figure 4 The antenna port array 40 has dimensions of (M, N) and the number of ports is M×N. Taking antenna port 22 as an example, antenna port 22 is adjacent to antenna port 21 and antenna port 23 in the row direction, and antenna port 22 is adjacent to antenna port 12 and antenna port 32 in the column direction.

[0117] In condition 3, the rectangular shape of the outer contour of the antenna port group indicates that the number of antenna ports in the row direction of the antenna port array is different from the number of antenna ports in the column direction of the antenna port array.

[0118] For example, please refer to Figure 4 For antenna port group 401, antenna port group 401 includes 8 antenna ports, namely antenna port 34, antenna port 35, antenna port 36, antenna port 37, antenna port 44, antenna port 45, antenna port 46, and antenna port 47. Among them, antenna port group 201 has 4 antenna ports in the row direction of the antenna port array, and antenna port group 401 has 2 antenna ports in the column direction of the antenna port array.

[0119] In this embodiment, when determining the second antenna port group, the terminal device first selects several antenna ports according to the measurement results of the reference signal, and then forms the second antenna port group according to at least one of the above conditions 1 to 4.

[0120] Continue to refer to Figure 3 In step 303, the terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report.

[0121] In this embodiment, the measurement report indicates one or more second antenna port groups.

[0122] In practice, the measurement report includes at least one of the following:

[0123] Identifiers of the antenna port subarrays included in one or more second antenna port groups; or,

[0124] An identifier of a reference signal whose measurement result is greater than a second threshold among the reference signals transmitted by the antenna port subarrays included in one or more second antenna port groups.

[0125] In this embodiment, since the second antenna port group is determined by the terminal device, if the terminal device reports the identifier of the second antenna port group, the network device cannot know which antenna ports are included in the second antenna port group. Therefore, the terminal device can report the identifier of the antenna port subarray included in the second antenna port group, or the identifier of the reference signal whose measurement result is greater than the second threshold in the reference signal sent by the antenna port subarray.

[0126] For example, the terminal device identifies two second antenna port groups: second antenna port group 1 includes antenna port subarray 13 and antenna port subarray 14 in the first antenna port group 1; second antenna port group 2 includes antenna port subarray 19 and antenna port subarray 20 in the first antenna port group 1. In this case, the terminal device can report the identifiers of antenna port subarray 13, antenna port subarray 14, antenna port subarray 19, and antenna port subarray 20.

[0127] For example, if the measurement result of the reference signal 14 transmitted by the antenna port subarray 14 is greater than the second threshold, and the measurement result of the reference signal 20 transmitted by the antenna port subarray 20 is greater than the second threshold, the terminal device can also report the identifiers of the reference signal 14 and the reference signal 20.

[0128] It should be noted that the specific value of the second threshold can be specified by the communication standard protocol or configured by the network device; this application does not impose any restrictions on this.

[0129] In one specific embodiment of the above-described Example 2, the antenna port subarrays included in the second antenna port group are different from the antenna subarrays included in the first antenna port group.

[0130] For example, the second antenna port group includes antenna port subarrays 1 to 4, and the first antenna port group includes antenna port subarrays 5 to 8.

[0131] In this embodiment, among the reference signals transmitted by each antenna port subarray of the second antenna port group, there is a reference signal whose measurement result is greater than or equal to the second threshold.

[0132] In another specific embodiment of the above-described embodiment 2, the antenna port subarrays included in the second antenna port group are different from the antenna subarrays included in the first antenna port group.

[0133] For example, the second antenna port group includes antenna port subarrays 1 to 4, and the first antenna port group includes antenna port subarrays 3 to 6. Both the second antenna port group and the first antenna port group include antenna port subarrays 3 and 4.

[0134] In this embodiment, among the reference signals transmitted by each antenna port subarray of the second antenna port group, there is a reference signal whose measurement result is greater than the maximum or minimum value among the measurement results of the reference signals transmitted by the antenna port subarray of the first antenna port group.

[0135] Furthermore, the number of antenna port subarrays included in the second antenna port group is greater than or equal to the number of antenna port subarrays included in the first antenna port group.

[0136] In another specific embodiment of Example 2 above, the second antenna port group is the same as the first antenna port group. The second antenna port group being the same as the first antenna port group means that each antenna port subarray included in the second antenna port group is completely identical to each antenna subarray included in the first antenna port group.

[0137] For example, the second antenna port group includes antenna port subarrays 1 to 4, and the first antenna port group includes antenna port subarrays 1 to 4.

[0138] In this embodiment, among the reference signals transmitted by each antenna port subarray of the second antenna port group, there is a reference signal whose measurement result is greater than the maximum or minimum value among the measurement results of the reference signals transmitted by the antenna port subarray of the first antenna port group.

[0139] Those skilled in the art will understand that steps S301 to S303 can be considered as the above. Figure 2 The execution steps S201 to S202 in the illustrated embodiment correspond to each other, and they are complementary in their specific implementation principles and logic. Therefore, the explanation of the terms involved in this embodiment can be found by referring to... Figure 2 The relevant descriptions of the embodiments shown will not be repeated here.

[0140] Example 3: The terminal device detects that the measurement result of the reference signal transmitted by one or more antenna port subarrays in each of the N first antenna port groups is less than a first threshold, and the terminal device determines one or more second antenna port groups based on the measurement result of the reference signal transmitted by one or more antenna port subarrays in at least one antenna port subarray, and the terminal device sends a measurement report.

[0141] Compared with the aforementioned Embodiments 1 and 2, the triggering condition for the measurement report in this embodiment is that the measurement result of the reference signal transmitted by one or more antenna port subarrays in each of the N first antenna port groups is less than a first threshold, and the terminal device determines one or more second antenna port groups based on the measurement result of the reference signal transmitted by one or more antenna port subarrays in at least one antenna port subarray.

[0142] This embodiment can simultaneously indicate the antenna port with poor signal reception quality and its corresponding beam in the antenna port group currently providing communication services, as well as the antenna ports and their corresponding beams in other antenna port subarrays.

[0143] In this embodiment, the measurement report includes at least one of the following:

[0144] The identifiers of the N first antenna port groups; or...

[0145] The identifier of the antenna port subarray whose measured value of the transmitted reference signal is less than a first threshold in the N first antenna port groups; or,

[0146] The identifier of the reference signal whose measurement result is less than a first threshold among the reference signals transmitted by the antenna port subarrays in the N first antenna port groups.

[0147] In addition, the measurement report may include at least one of the following:

[0148] Identifiers of the antenna port subarrays included in one or more second antenna port groups; or,

[0149] An identifier of a reference signal whose measurement result is greater than a second threshold among the reference signals transmitted by the antenna port subarrays included in one or more second antenna port groups.

[0150] In Embodiments 2 and 3 above, among the reference signals transmitted by each antenna port subarray in one or more second antenna port groups, the reference signals whose measurement results are greater than or equal to a second threshold have a quasi-co-location relationship.

[0151] In this embodiment, the terminal device constructs a second antenna port group based on an antenna port subarray with the same optimal beam, thereby enabling the second antenna port group to use the same beam to provide communication services to the terminal device in the subsequent implementation, thus improving communication efficiency.
