In the process of beam measurement and reporting of the terminal device, each transmission beam corresponds to a reference signal. After measuring a plurality of reference signals, the terminal device reports an identifier of a reference signal corresponding to at least one optimal beam. In the existing protocol, each antenna port in the antenna port array of the network device has similar channel conditions. Therefore, the network device and the terminal device only need to train an optimal beam of 1 or 2 antenna ports, and can obtain the optimal beam of all antenna ports.

[0005] 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.

[0047] The communication system to which the embodiments of the present application are applicable includes, but is not limited to, a Long Term Evolution (LTE) system, a 5th-Generation (5G) system, a New Radio (NR) system, and a future evolution system or a plurality of communication fusion systems.

[0048] The present application mainly relates to communication between a terminal device and a network device. Among them:

[0049] The network device in the embodiments of the present application can also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device). The network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the device providing the base station function in the second generation (2nd-Generation, 2G) network includes a base transceiver station (BTS), the device providing the base station function in the third generation (3rd-Generation, 3G) network includes a node B (NodeB), the device providing the base station function in the fourth generation (4th-Generation, 4G) network includes an evolved node B (eNB), in a wireless local area network (WLAN), the device providing the base station function is an access point (AP), the device providing the base station function in the NR includes a next generation node base station (gNB), and a continuously evolved node B (ng-eNB), wherein the gNB and the terminal device communicate with each other using NR technology, the ng-eNB and the terminal device communicate with each other using evolved universal terrestrial radio access (E-UTRA) technology, and the gNB and the ng-eNB are both connected to a 5G core network. The network device in the embodiments of the present application also includes devices providing base station functions in future new communication systems and the like.

[0050] The terminal equipment in the embodiments of the present application can refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment can also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal equipment in a future 5G network or a terminal equipment in a future evolved Public Land Mobile Network (PLMN), etc. The embodiments of the present application are not limited thereto. The terminal equipment can also be referred to as user equipment (User Equipment, UE), terminal, etc.

[0051] As described in the background, under the spatial non-stationary condition, the existing beam management process cannot monitor the optimal beams of multiple ports in the antenna port array.

[0052] Specifically, under the spatial non-stationary condition, the antenna port array can be divided into one or more visible regions, each visible region containing adjacent antenna ports and having similar channel conditions. The visible region can represent the range of the terminal equipment visible to the antenna array. For example, the network device can use the reference signal to find the visible region of the terminal equipment on the antenna panel in the transmission path with the terminal equipment. Under the spatial non-stationary condition, the number of antenna ports in the visible region can vary, and different visible regions have different optimal beams.

[0053] Specifically, as shown in FIG. 1, UE1 is only visible to the visible region 1 of the array, UE2 is only visible to the visible regions 1 and 2, UE3 is only visible to the visible region 2, and UE4 is only visible to the visible regions 2 and 3.

[0054] Therefore, how to measure and report the visible region under the spatial non-stationary condition is a problem to be solved.

[0055] In the embodiments of the present application, the terminal equipment indicates the antenna port and its corresponding beam to the network device through the measurement result of the reference signal, realizes the measurement and reporting of multiple ports and their corresponding optimal beams, and assists the network device in making switching decisions to provide better communication services for the terminal equipment.

[0056] Further, by measuring and reporting the N first antenna port groups and / or the one or more second antenna port groups, the terminal device can measure and report the visible area.

[0057] Firstly, some terms related to the embodiments of the present application are introduced, so as to facilitate the understanding of those skilled in the art.

[0058] The antenna port array in the embodiments of the present application can also be referred to as an antenna set, a beam set, an antenna array, an antenna panel, an antenna panel group, an antenna panel set, a logical entity, an entity or an antenna entity, etc. The size of the antenna port array refers to the number of antenna ports in one dimension or two dimensions of the antenna port array.

[0059] The antenna port group in the embodiments of the present application can also be referred to as an antenna group, an antenna port set, etc.

[0060] The antenna port sub-array in the embodiments of the present application refers to an antenna port sub-array obtained by dividing the antenna port array according to a certain size. The antenna port sub-array can be a part of the antenna port array. The antenna port sub-array can also be referred to as an antenna sub-array, an antenna port sub-array, a beam sub-set, etc. The size of the antenna port sub-array refers to the number of antenna ports in one dimension or two dimensions of the antenna port sub-array.

[0061] For example, the size of the antenna port array (M, N) indicates that the number of ports in one direction of the antenna port array is M and the number of ports in the other direction is N; the size of the antenna port sub-array (X, Y) indicates that the number of ports in one direction of the antenna port sub-array is X and the number of ports in the other direction is Y, wherein X is less than M and Y is less than N, and M and N are positive integers. One direction is the horizontal direction and the other direction is the vertical direction; or one direction is the vertical direction and the other direction is the horizontal direction.

[0062] For example, the relationship between the antenna port array, the antenna port group and the antenna port sub-array can be that the antenna port array includes at least one antenna port group, and each antenna port group can include at least one antenna port sub-array.

[0063] In the 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 for CSI measurement.

[0064] In the embodiments of the present application, the antenna port array is a super large antenna array, has a large number of antenna ports, and the range of the near-field region of the antenna port array gradually becomes non-negligible. The terminal device can perform near-field communication with the network device in the region.

[0065] The embodiments of the present application are mainly used in a near-field communication scenario. 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 sensing-integrated design, physical layer security, and the like.

[0066] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0067] Referring to FIG. 2, the method provided by the present application specifically includes the following steps:

[0068] Step 201: The network device sends a reference signal through each antenna port subarray in the at least one antenna port subarray. Correspondingly, the terminal device receives the reference signal from each antenna port subarray in the at least one antenna port subarray.

[0069] In the embodiments, the terminal device can achieve measurement of the reference signal by receiving the reference signal from each antenna port subarray in the at least one antenna port subarray, obtain a measurement result of the reference signal, and the measurement result of the reference signal can represent the signal reception quality of the reference signal. Further, the measurement of each antenna port subarray in the at least one antenna port subarray is achieved, and a measurement result of the antenna port subarray is obtained, which can represent the signal reception quality of the antenna port subarray.

[0070] Among them, the M antenna port subarrays in the 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, the at least one antenna subarray includes at least one first antenna port group. For example, the at least one first antenna port group can be composed of M antenna port subarrays. Further, the at least one antenna subarray can include other antenna subarrays in addition to the at least one first antenna port group.

[0071] Further, the at least one first antenna port group is an antenna port group that can be used for data transmission. That is, the at least one first antenna port group can provide communication services for the terminal device.

[0072] For example, the network device sends downlink data to the terminal device and receives uplink data through each antenna port subarray in the antenna port group 1, the antenna port group 2, the antenna port group 3 and the antenna port group 4, and the antenna port group 1, the antenna port group 2, the antenna port group 3 and the antenna port group 4 are the first antenna port group.

[0073] In this embodiment, the terminal device can measure the first antenna port group providing the communication service by measuring the reference signals from the M antenna port subarrays, so as to obtain the signal receiving quality of the first antenna port group.

[0074] Specifically, the measurement result of the reference signal can include at least one of the following:

[0075] 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, reception time, etc.

[0076] Step 202: The terminal device sends a measurement report based on the measurement result of the reference signal sent by one or more antenna port subarrays in the at least one antenna port subarray. Correspondingly, the network device receives the measurement report.

[0077] In this embodiment, the measurement report indicates N first antenna port groups in the at least one first antenna port group; and / or, the measurement report indicates one or more second antenna port groups, and each second antenna port group includes one or more antenna port subarrays in the at least one antenna port subarray.

[0078] In this embodiment, the terminal device indicates the antenna port and its corresponding beam to the network device by the measurement result of the reference signal, realizes the measurement and reporting of the multiple ports and their corresponding optimal beams, and assists the network device in making the switching decision to provide better communication services for the terminal device. For example, the measurement report indicates N first antenna port groups. In this case, the terminal device indicates only the antenna port in the antenna port group currently providing communication services and its corresponding beam to the network device.

[0079] 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 except the antenna ports in the N first antenna port groups and their corresponding beams.

[0080] 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 indicate the antenna port in the antenna port group currently providing communication services and its corresponding beam, and the antenna port in the other antenna port subarray and its corresponding beam.

[0081] It should be noted that the serial numbers of the steps in this embodiment do not represent the limitation of the execution order of the steps.

[0082] It can be understood that in specific implementation, the communication method can be realized in the form of a software program running in a processor integrated in a chip or a chip module. The method can also be realized in the form of software combined with hardware, and the present application does not make any limitation.

[0083] The following describes different embodiments according to different trigger conditions of the measurement report.

[0084] In the case where the terminal device detects that the measurement result of the reference signal sent by one or more antenna port subarrays included in each of the N first antenna port groups is less than the first threshold, the terminal device sends the measurement report.

[0085] In this embodiment, the trigger condition of the measurement report is that the measurement result of the reference signal sent by one or more antenna port subarrays included in each of the N first antenna port groups is less than the first threshold. In other words, the terminal device determines one or more antenna port subarrays whose measurement result of the reference signal is less than the first threshold, and takes the first antenna port group in which the one or more antenna port subarrays are located as the N first antenna port groups.

[0086] In this embodiment, the measurement result of the reference signal sent by the antenna port subarray is less than the first threshold, which means that the signal receiving quality of the antenna port subarray is poor. That is, the terminal device reports the measurement report in the case that the first antenna port group available for data transmission is poor, to assist the network device to make handover decision.

[0087] In this embodiment, the measurement report includes at least one of the following:

[0088] the identification of the N first antenna port groups; or,

[0089] the identification of the antenna port subarray in the N first antenna port groups, whose measurement result of the reference signal sent is less than the first threshold; or,

[0090] the identification of the reference signal in the reference signal sent by the antenna port subarray in the N first antenna port groups, whose measurement result is less than the first threshold.

[0091] Since the reference signal is sent by the antenna port subarray, the identification of the reference signal can indirectly indicate the antenna port subarray.

[0092] For example, N=4, the terminal device measures the reference signal from the antenna port subarray in the 8 first antenna port groups (group 1 to group 8), and finds that there is at least one antenna port subarray in the first antenna port group 1 to the first antenna port group 4 whose measurement result of the reference signal sent is less than the first threshold. In this case, the terminal device can report the identification of the first antenna port group 1 to the first antenna port group 4, that is, 1, 2, 3 and 4.

[0093] For another example, each first antenna port group includes 4 antenna port subarrays, the measurement result of the reference signal 1 sent by the antenna port subarray 1 and the reference signal 2 sent by the antenna port subarray 2 in the first antenna port group 1 is less than the first threshold, the measurement result of the reference signal 5 sent by the antenna port subarray 5 in the first antenna port group 2 is less than the first threshold, the measurement result of the reference signal 10 sent by the antenna port subarray 10 in the first antenna port group 3 is less than the first threshold, and the measurement result of the reference signal 15 sent by the antenna port subarray 15 in the first antenna port group 4 is less than the first threshold. In this case, the terminal device can report the identification of the antenna port subarray 1, the antenna port subarray 2, the antenna port subarray 5, the antenna port subarray 10 and the antenna port subarray 15.

[0094] For another example, the terminal device can also report the identification of the reference signal 1, the reference signal 2, the reference signal 5, the reference signal 10 and the reference signal 15.

[0095] It should be noted that the specific value of the first threshold can be specified by a communication standard protocol or configured by a network device, and the present application does not limit this.

[0096] In the embodiment, the terminal device determines the one or more second antenna port groups based on measurement results of the reference signals transmitted by the one or more antenna port subarrays of the at least one antenna port subarray.

[0097] In the embodiment, the trigger condition of the measurement report is that the terminal device determines the one or more second antenna port groups based on measurement results of the reference signals transmitted by the one or more antenna port subarrays of the at least one antenna port subarray.

[0098] Specifically, refer to FIG. 3, which shows a flow of a communication method.

[0099] In step 301, the terminal device receives reference signals from each antenna port subarray of the at least one antenna port subarray.

[0100] In step 302, the terminal device determines the one or more second antenna port groups based on measurement results of the reference signals transmitted by the one or more antenna port subarrays of the at least one antenna port subarray.

[0101] In the embodiment, the terminal device can determine the antenna port group with better signal reception quality, i.e., the one or more second antenna port groups, according to the measurement results of the reference signals transmitted by the antenna port subarrays. That is, the terminal device reports the measurement report in the case of finding the antenna port group with better reception quality to assist the network device in making a switching decision.

[0102] In a specific embodiment, in the reference signals transmitted by each antenna port subarray included in the second antenna port group, there is a measurement result of a reference signal greater than or equal to a second threshold.

[0103] In the embodiment, the terminal device determines the second antenna port group with better reception quality by comparing the measurement results of the reference signals with an absolute value, i.e., the second threshold. In other words, the terminal device determines the antenna port subarray with a measurement result greater than or equal to the second threshold, and determines the one or more second antenna port groups according to the antenna port subarray.

[0104] In another specific embodiment, in the reference signals transmitted by each antenna port subarray included in the second antenna port group, there is a measurement result of a reference signal greater than the maximum or minimum value in the measurement results of the reference signals transmitted by the antenna port subarrays included in the first antenna port group.

[0105] In this embodiment, the terminal device determines the second antenna port group with better receiving quality by comparing the measurement results of the reference signals with a relative value (i.e. the measurement results of the reference signals transmitted by the antenna port subarray included in the first antenna port group).

[0106] In one non-limiting embodiment, when determining the second antenna port group, the terminal device can determine the second antenna port group according to at least one of the following conditions, i.e. the second antenna port group needs to satisfy at least one of the following conditions 1-4.

[0107] Condition 1: the channel parameters between the multiple antenna ports in each second antenna port group are the same, and the channel parameters of the antenna ports are determined based on at least one reference signal measurement result.

[0108] Condition 2: the multiple antenna ports in each second antenna port group are adjacent in the antenna port array.

[0109] Condition 3: the multiple antenna ports in each second antenna port group form a rectangular array.

[0110] Condition 4: the number of antenna ports in each second antenna port group can be the same or different.

[0111] In Condition 1, the channel parameters of the antenna ports can be at least one of the following: the received power of the reference signal transmitted by the antenna port, the average delay, the frequency offset, and the Doppler shift. The channel parameters of the antenna ports can represent the channel quality of the antenna ports. By making the channel parameters between the multiple antenna ports in each antenna port group the same, spatial stationarity can be satisfied between the multiple antenna ports in each antenna port group.

[0112] That is, when determining the second antenna port group, the terminal device considers dividing the multiple ports with the same channel parameters into the same antenna port group.

[0113] For example, when 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 RSRP1 and RSRP2 are the same in value, or the difference between RSRP1 and RSRP2 is less than a preset threshold, it indicates that the channel parameters of antenna port 1 and antenna port 2 are the same.

[0114] For example, when the channel parameter is the received power of the reference signal, the channel parameter can be directly obtained from the measurement result of the reference signal.

[0115] For example, when the channel parameter is the average delay, the channel parameter can be calculated according to the transmission delay of the reference signal in the measurement result of the reference signal. For example, antenna port 1 transmits the same reference signal four times at different times, and the terminal device measures the four reference signals to obtain four measurement results, and then the average delay of the antenna port 1 is the average value of the four transmission delays in the four measurement results.

[0116] In condition 2, since the spatial stationarity is more likely to be satisfied between the antenna ports adjacent in position, the terminal device considers dividing the multiple antenna ports adjacent in position in the antenna port array into the same antenna port group when determining the second antenna port group.

[0117] Specifically, each antenna port has a position in the antenna port array, and two antenna ports adjacent in position in the antenna port array refer to that the two antenna ports are adjacent in the row direction or the column direction of the antenna port array. For details, please refer to FIG. 4, the size of the antenna port array 40 is (M, N), and the number of ports of the antenna port array is M*N. Taking the antenna port 22 as an example, the antenna port 22 is adjacent in position to the antenna port 21 and the antenna port 23 in the row direction, and the antenna port 22 is adjacent in position to the antenna port 12 and the antenna port 32 in the column direction.

[0118] 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.

[0119] For example, referring to FIG. 4, for the antenna port group 401, the antenna port group 401 includes 8 antenna ports, which are the antenna port 34, the antenna port 35, the antenna port 36, the antenna port 37, the antenna port 44, the antenna port 45, the antenna port 46 and the antenna port 47. Among them, the number of antenna ports of the antenna port group 201 in the row direction of the antenna port array is 4, and the number of antenna ports of the antenna port group 401 in the column direction of the antenna port array is 2.

[0120] In this embodiment, when determining the second antenna port group, the terminal device first selects a plurality of antenna ports according to the measurement result of the reference signal, and then forms the second antenna port group according to at least one of the above conditions 1 to 4.

[0121] Continuing to refer to FIG. 3, in step 303, the terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report.

[0122] In this embodiment, the measurement report indicates one or more second antenna port groups.

[0123] In a specific implementation, the measurement report includes at least one of the following:

[0124] an identity of an antenna port subarray included by the one or more second antenna port groups; or

[0125] an identity of a reference signal whose measurement result is greater than a second threshold value, from among the reference signals transmitted by the antenna port subarray included by the one or more second antenna port groups.

[0126] In this embodiment, since the second antenna port groups are determined at the terminal device side, if the terminal device reports the identity of the second antenna port groups, the network device cannot know which antenna ports are included by the second antenna port groups, therefore the terminal device can report the identity of the antenna port subarray included by the second antenna port groups, or the identity of the reference signal whose measurement result is greater than a second threshold value, from among the reference signals transmitted by the antenna port subarray.

[0127] For example, the terminal device determines two second antenna port groups, the second antenna port group 1 includes the antenna port subarray 13 and the antenna port subarray 14 in the first antenna port group 1, and the second antenna port group 2 includes the antenna port subarray 19 and the antenna port subarray 20 in the first antenna port group 1. In this case, the terminal device can report the identities of the antenna port subarray 13, the antenna port subarray 14, the antenna port subarray 19 and the antenna port subarray 20.

[0128] For another example, the measurement result of the reference signal 14 transmitted by the antenna port subarray 14 is greater than the second threshold value, and the measurement result of the reference signal 20 transmitted by the antenna port subarray 20 is greater than the second threshold value, the terminal device can also report the identities of the reference signal 14 and the reference signal 20.

[0129] It should be noted that the specific value of the second threshold value can be specified by a communication standard protocol or configured by the network device, and the present application does not limit this.

[0130] In one specific implementation of the above embodiment 2, each antenna port subarray included by the second antenna port groups is different from each antenna subarray included by the first antenna port groups.

[0131] For example, the second antenna port groups include the antenna port subarray 1 to the antenna port subarray 4, and the first antenna port groups include the antenna port subarray 5 to the antenna port subarray 8.

[0132] In this embodiment, there is a reference signal whose measurement result is greater than or equal to the second threshold value, from among the reference signals transmitted by each antenna port subarray included by the second antenna port groups.

[0133] In another specific implementation of the above-described embodiment 2, each antenna port subarray included in the second antenna port group is partially different from each antenna subarray included in the first antenna port group.

[0134] For example, the second antenna port group includes antenna port subarray 1 to antenna port subarray 4, and the first antenna port group includes antenna port subarray 3 to antenna port subarray 6. The second antenna port group and the first antenna port group both include antenna port subarray 3 and antenna port subarray 4.

[0135] In this embodiment, for each antenna port subarray included in the second antenna port group, there is one reference signal whose measurement result is greater than the maximum or minimum of the measurement results of the reference signals transmitted by the antenna port subarrays included in the first antenna port group.

[0136] Further, 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.

[0137] In another specific implementation of the above-described embodiment 2, 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 the same as each antenna subarray included in the first antenna port group.

[0138] For example, the second antenna port group includes antenna port subarray 1 to antenna port subarray 4, and the first antenna port group includes antenna port subarray 1 to antenna port subarray 4.

[0139] In this embodiment, for each antenna port subarray included in the second antenna port group, there is one reference signal whose measurement result is greater than the maximum or minimum of the measurement results of the reference signals transmitted by the antenna port subarrays included in the first antenna port group.

[0140] Those skilled in the art understand that the steps S301 to S303 can be regarded as execution steps corresponding to the steps S201 to S202 of the embodiment shown in FIG. 2 described above, and the two are complementary in specific implementation principles and logic. Thus, the explanations of the terms involved in this embodiment can refer to the related descriptions of the embodiment shown in FIG. 2, which will not be repeated here.

[0141] In the embodiment, the terminal device detects that the measurement result of the reference signal transmitted by each of the one or more antenna port subarrays included in each of the N first antenna port groups is less than the first threshold value, and the terminal device determines the one or more second antenna port groups based on the measurement result of the reference signal transmitted by one or more of the at least one antenna port subarray, and the terminal device transmits the measurement report.

[0142] Compared with the preceding embodiment 1 and embodiment 2, in the embodiment, the triggering condition of the measurement report is that the measurement result of the reference signal transmitted by each of the one or more antenna port subarrays included in each of the N first antenna port groups is less than the first threshold value, and the terminal device determines the one or more second antenna port groups based on the measurement result of the reference signal transmitted by one or more of the at least one antenna port subarray.

[0143] The embodiment can simultaneously indicate the antenna port and the corresponding beam with poor signal reception quality in the antenna port group currently providing the communication service, and the antenna port and the corresponding beam in the other antenna port subarray.

[0144] In the embodiment, the measurement report includes at least one of the following:

[0145] an identifier of the N first antenna port groups; or

[0146] an identifier of the antenna port subarray whose measurement result of the transmitted reference signal is less than the first threshold value in the N first antenna port groups; or

[0147] an identifier of the reference signal whose measurement result is less than the first threshold value in the reference signal transmitted by the antenna port subarray in the N first antenna port groups.

[0148] In addition, the measurement report can further include at least one of the following:

[0149] an identifier of the antenna port subarray included in the one or more second antenna port groups; or

[0150] an identifier of the reference signal whose measurement result is greater than the second threshold value in the reference signal transmitted by the antenna port subarray included in the one or more second antenna port groups.

[0151] In the above-mentioned embodiment 2 and embodiment 3, the reference signals whose measurement results are greater than or equal to the second threshold value in the reference signals transmitted by each of the antenna port subarrays in the one or more second antenna port groups have a quasi-co-location relationship

[0152] In this embodiment, the terminal device constructs a second antenna port group based on the antenna port subarray with the same optimal beam, so that the second antenna port group can provide communication services for the terminal device using the same beam in the subsequent implementation, thereby improving the communication efficiency.
