[0053] The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure and are not to be construed as limiting the present disclosure. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other unless there is a conflict.

[0054] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0055] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0056] The Release 18 study will support NR technology in selected dedicated spectrum bands (n8, n26, n28, and n100) for Long Term Evolution (LTE) and General Mobile System for Railways (GSM-R). These bands primarily provide communication services for power systems and railway systems, as well as for public protection and disaster relief services in certain countries and regions. These bands support only 15 kHz subcarrier spacing and system bandwidths of 5 MHz and 3 MHz. Based on the NR and LTE RF channel bandwidth requirements, the number of available RBs for a 5 MHz channel is 25; based on the LTE RF channel bandwidth requirements, the number of available RBs for a 3 MHz channel is 15.

[0057] Currently, in existing NR systems, PBCH transmission occupies 20 RBs. However, for dedicated spectrum with bandwidths less than 5 MHz, such as 3 MHz and 2.8 MHz to 3.6 MHz, the channel bandwidth cannot accommodate all PBCH transmissions. Therefore, it is necessary to consider how to improve PBCH transmission performance. One approach is to reduce the PBCH payload length for dedicated spectrum to reduce unnecessary information bit overhead. However, for PBCH with a reduced payload length, the traditional PBCH payload interleaving pattern will no longer be applicable, so the corresponding communication processing solution needs to be redefined.

[0058] To this end, this embodiment proposes a communication processing method and apparatus that can process PBCHs with reduced payload length using a newly designed payload interleaving pattern. This clarifies base station and terminal behavior and ensures appropriate PBCH processing at both the transmitting and receiving ends. This improves PBCH transmission performance while meeting a wider range of communication needs.

[0059] The communication processing method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0060] Fig. 1 shows a structural diagram of a communication processing system according to an embodiment of the present disclosure. As shown in Fig. 1 , the system architecture may include a network device 11 and a UE 12. The network device 11 and the UE 12 may communicate with each other.

[0061] In one example, the network device 11 may be an entity on the network side for transmitting or receiving signals. For example, the network device 11 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device 11. The network device 11 provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0062] In one example, UE 12 can be referred to as a terminal, user equipment, mobile station (MS), mobile terminal (MT), etc. UE 12 can also be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by UE 12.

[0063] In some examples, since the traditional PBCH payload interleaving mode is no longer applicable to the PBCH with a reduced payload length, this embodiment may design a new corresponding payload interleaving mode. Accordingly, the network device 11 may interleave the payload of the PBCH according to the payload interleaving mode corresponding to the PBCH, wherein the payload length of the PBCH is less than a first threshold (such as the payload length of the PBCH of the existing NR system); then the network device 11 transmits the PBCH to the UE 12 on the first frequency band (such as the bandwidth is less than the second threshold). The UE 12 may receive the PBCH transmitted by the network device 11 on the first frequency band; and then deinterleave the payload of the PBCH according to the payload interleaving mode corresponding to the PBCH.

[0064] In some examples, since the conventional PBCH payload interleaving mode is no longer applicable for a PBCH with a reduced payload length, this embodiment may not consider the payload interleaving mode of the PBCH, i.e., the payload of the PBCH is not interleaved. Accordingly, network device 11 may send a PBCH to the UE on the first frequency band, wherein the payload size of the PBCH is less than the first threshold, and the payload of the PBCH is not interleaved. UE 12 may receive the PBCH sent by network device 11 on the first frequency band, and since the payload of the PBCH is not interleaved, no deinterleaving is required.

[0065] Further, to illustrate the specific execution process of the network device, Figure 2 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to the network device side (such as the network device 11 in Figure 1) and may include the following steps.

[0066] Step 201: A network device sends a first PBCH on a first frequency band.

[0067] The payload in the first PBCH is interleaved in a first interleaving pattern.

[0068] Among them, the payload length in the first PBCH is less than the first threshold, and the first threshold can be pre-set according to actual needs. The bandwidth of the first frequency band is less than the second threshold, such as the second threshold can be 5MHz. For example, for dedicated spectrum with a bandwidth less than 5MHz such as 3MHz and 2.8MHz~3.6MHz, its channel bandwidth cannot accommodate the entire PBCH, so the payload length of the PBCH can be reduced. The first PBCH in this embodiment can be a PBCH with a reduced payload length. The payload length of the first PBCH is less than a certain threshold, and this embodiment can design a new corresponding payload interleaving mode for it, that is, a first interleaving mode. Then, according to the first interleaving mode, the payload of the first PBCH is interleaved, such as interleaving the entire payload of the PBCH after the physical layer information bits are added. The specific interleaving process can be similar to the payload interleaving process of the PBCH of the existing NR system.

[0069] In the communication processing method provided in this embodiment, the network device can interleave the payload of the first PBCH with a payload length less than a first threshold according to a newly designed payload interleaving mode corresponding thereto, i.e., the first interleaving mode, and then send the first PBCH on a first frequency band (e.g., a bandwidth less than 5 MHz). While improving the PBCH transmission performance, more communication needs can be met.

[0070] Figure 3 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. Based on the embodiment shown in Figure 2, as shown in Figure 3, the method is applied to the sending network device side (such as the network device 11 in Figure 1) and may include the following steps.

[0071] Step 301: A network device determines a first interleaving pattern, and interleaves a payload of a first PBCH according to the first interleaving pattern.

[0072] The first interleaving pattern may be a payload interleaving pattern corresponding to a first PBCH, where the payload length in the first PBCH is less than a first threshold. In some examples, the first threshold may be the payload length of an NR system PBCH, such as the payload length of an existing NR system PBCH. The payload of the first PBCH may be applicable to a dedicated spectrum system less than a second threshold. For example, if the second threshold is 5 MHz, the payload of the first PBCH may be applicable to a dedicated spectrum system less than 5 MHz.

[0073] In some examples, determining the first interleaving mode in step 301 may specifically include: determining the first interleaving mode based on the information bit length of the first PBCH and / or the cyclic redundancy check (CRC) bit length of the first PBCH.

[0074] For example, corresponding payload interleaving modes can be designed for different information bit lengths and / or CRC bit lengths of PBCH, such as different information bit lengths and / or CRC bit lengths of PBCH correspond to different payload interleaving modes.

[0075] Further, in some examples, determining the first interleaving pattern based on the information bit length of the first PBCH and / or the CRC bit length of the first PBCH may specifically include: determining the first interleaving pattern from an interleaving pattern set based on the information bit length of the first PBCH and / or the CRC bit length of the first PBCH, the interleaving pattern set including one or more interleaving patterns.

[0076] For example, the information bit length of the PBCH may include but is not limited to several different information bit lengths such as 22 bits, 28 bits, 26 bits, 24 bits, 23 bits, and 25 bits, wherein different information bit lengths correspond to different field deletion situations.

[0077] The CRC bit length of the PBCH may include but is not limited to: 24 bits, 16 bits.

[0078] When the information bit length is 22 bits and the CRC bit length is 24 bits, interleaving can be performed according to the interleaving pattern shown in Table 1. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0079] Table 1

[0080] When the information bit length is 22 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 2. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0081] Table 2

[0082] When the information bit length is 28 bits and the CRC bit length is 24 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 3. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0083] Table 3

[0084] When the information bit length is 28 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 4. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0085] Table 4

[0086] When the information bit length is 26 bits and the CRC bit length is 24 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 5. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0087] Table 5

[0088] When the information bit length is 26 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 6. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0089] Table 6

[0090] When the information bit length is 24 bits and the CRC bit length is 24 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 7. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0091] Table 7

[0092] When the information bit length is 24 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 8. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0093] Table 8

[0094] When the information bit length is 23 bits and the CRC bit length is 24 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 9. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0095] Table 9

[0096] When the information bit length is 23 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 10. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0097] Table 10

[0098] When the information bit length is 25 bits and the CRC bit length is 24 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 11. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0099] Table 11

[0100] When the information bit length is 25 bits and the CRC bit length is 16 bits, interleaving can be performed according to the payload interleaving pattern shown in Table 12. In the table, j represents the bit position before payload interleaving, and G(j) represents the bit position after payload interleaving.

[0101] Table 12

[0102] Tables 1 to 12 are merely exemplary illustrations of the interleaving pattern, and the mapping relationship between j and G(j) may not be limited to those shown in Tables 1 to 12.

[0103] Based on the payload interleaving patterns shown in Tables 1 to 12 above, an interleaving pattern set can be obtained. Based on the interleaving pattern set, a corresponding payload pattern can be determined from the interleaving pattern set according to the information bit length and CRC bit length of the first PBCH as a first interleaving pattern. The payload of the first PBCH is then interleaved according to the first interleaving pattern.

[0104] In some examples, in a first PBCH, a known information bit (the known bit) is located at a bit position whose reliability is lower than a third threshold, wherein the known bit does not include an SSB index indication. Accordingly, after interleaving the payload of the first PBCH, the method of this embodiment may further include: determining a channel reliability ranking corresponding to the first PBCH; and determining that the reliability of the known bit is lower than the third threshold.

[0105] For example, considering the SSB reception in a specific scenario, such as a UE in a connected state receiving the SSB of the cell, the UE can know or deduce the time domain related information carried in the first PBCH in advance. These time domain related information bits include: system frame SFN (10 bits) and half-frame indication (1 bit). In addition, the half-frame indication will also be carried by the demodulation reference signal (DMRS), that is, the UE can obtain the half-frame time information by detecting the DMRS. These time domain related information bits are also called the known bit, where the known bit does not include the SSB index indication (3 bits).

[0106] After interleaving the payload of the first PBCH and reorganizing it with the reliability-based position, the channel reliability ranking corresponding to the first PBCH is obtained, and the reliability of the known bit is determined to be below a certain threshold. For example, the known bit can be equated with a frozen bit and placed in a bit position with relatively low reliability, while the CRC bit and the unknown information bit (unknown bit) are placed in a bit position with relatively high reliability. The channel reliability ranking of the known bit is related to the CRC length, the information bit length, and the code length. In this embodiment, the code length can be 512 bits. Considering that the channel reliability occupied by the CRC in the fixed CRC and information bit combination is relatively fixed, different combinations have different reliability rankings.

[0107] For example, 1. When the information bit length is 28 bits, 26 bits, 25 bits, 24 bits, or 23 bits, and the CRC bit length is 24 bits, the channel reliability ranking corresponding to the known bit (SFN bit + half-frame indication) can be as follows:

[0108] 10-9-8-7-6-5-4-1-0-3-2. 10 represents the reliability of the highest bit of the system frame (SFN), 9 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of the SFN, and 2 represents the half-frame indicator. Higher values ​​indicate higher reliability.

[0109] 2. When the information bit length is 26 bits and the CRC bit length is 16 bits, the channel reliability ranking corresponding to the known bit (SFN bit + half-frame indication) can be as follows:

[0110] 11-10-8-7-6-5-4-1-0-3-2. 11 represents the reliability of the highest bit of SFN, 10 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of SFN, 2 represents the half-frame indicator, 0 also represents the lowest channel reliability bit among the (26+16) bits, and 11 also represents the 12th lowest channel reliability bit among the (26+16) bits.

[0111] 3. When the information bit length is 24 bits and the CRC bit length is 16 bits, the channel reliability ranking corresponding to the known bit (SFN bit + half-frame indication) can be as follows:

[0112] 12-10-9-8-6-5-4-1-0-3-2. 12 represents the reliability of the highest bit of SFN, 10 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of SFN, and 2 represents the half-frame indication.

[0113] 4. When the information bit length is 23 bits and the CRC bit length is 16 bits, the channel reliability ranking corresponding to the known bits (SFN bit + half-frame indication) can be as follows:

[0114] 12-11-9-8-7-5-4-1-0-3-2. 12 represents the reliability of the highest bit of SFN, 11 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of SFN, and 2 represents the half-frame indication.

[0115] 5. When the information bit length is 22 bits and the CRC bit length is 24 bits, the channel reliability ranking corresponding to the known bits (SFN bit + half-frame indication) can be as follows:

[0116] 12-9-8-7-6-5-4-1-0-3-2. 12 represents the reliability of the highest bit of SFN, 9 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of SFN, and 2 represents the half-frame indication.

[0117] 6. When the information bit length is 22 bits and the CRC bit length is 16 bits, the channel reliability ranking corresponding to the known bit (SFN bit + half-frame indication) can be as follows:

[0118] 13-11-10-8-7-6-4-1-0-3-2. 13 represents the reliability of the highest bit of SFN, 11 represents the reliability of the next bit, ..., 3 represents the reliability of the first bit of SFN, and 2 represents the half-frame indication.

[0119] Based on the above-mentioned several channel reliability rankings, the channel reliability ranking corresponding to the first PBCH can be determined according to the information bit length and CRC bit length of the first PBCH.

[0120] Step 302: The network device sends a first PBCH on a first frequency band.

[0121] By applying the communication processing method provided in this embodiment, the network device can interleave the payload of the first PBCH with a payload length less than the first threshold according to a newly designed payload interleaving mode corresponding thereto, i.e., the first interleaving mode, and then send the first PBCH on the first frequency band (e.g., a bandwidth less than 5 MHz). While improving the PBCH transmission performance, more communication needs can be met.

[0122] Figure 4 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to a UE side (such as UE 12 in Figure 1) and may include the following steps.

[0123] Step 401: A UE receives a first PBCH on a first frequency band.

[0124] The payload length in the first PBCH is less than a first threshold value, which can be pre-set according to actual needs. The payload in the first PBCH is interleaved in a first interleaving mode, and the bandwidth of the first frequency band is less than a second threshold value, such as 5 MHz.

[0125] In this embodiment, the UE may receive a first PBCH on a first frequency band. For a description of the first PBCH, see the embodiments shown in FIG. 2 and FIG. 3 , which are not described in detail here. After receiving the first PBCH, the UE may deinterleave the payload of the first PBCH according to the first interleaving mode.

[0126] By applying the communication processing method provided in this embodiment, the UE can deinterleave the payload of the first PBCH with a payload length less than the first threshold according to the newly designed payload interleaving mode corresponding to the first PBCH, that is, the first interleaving mode, so as to meet more communication needs while improving the PBCH transmission performance.

[0127] Figure 5 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to a UE side (such as UE 12 in Figure 1) and may include the following steps.

[0128] Step 501: A UE receives a first PBCH on a first frequency band.

[0129] The payload length of the first PBCH is less than a first threshold, the payload in the first PBCH is interleaved in a first interleaving pattern, and the bandwidth of the first frequency band is less than a second threshold. In some examples, the first threshold may be the payload length of the NR system PBCH, such as the payload length of the existing NR system PBCH. The payload of the first PBCH can be applied to a dedicated spectrum system less than the second threshold. For example, if the second threshold is 5 MHz, the payload of the first PBCH can be applied to a dedicated spectrum system less than 5 MHz.

[0130] Step 502: The UE determines a first interleaving mode.

[0131] In order to deinterleave the payload of the first PBCH, it is necessary to determine a first interleaving pattern, that is, a payload interleaving pattern newly designed for the first interleaving pattern. In some examples, step 502 may specifically include: determining the first interleaving pattern based on the information bit length and / or CRC bit length of the first PBCH. For example, based on the information bit length of the first PBCH and / or the CRC bit length of the first PBCH, the first interleaving pattern is determined from an interleaving pattern set, where the interleaving pattern set includes one or more interleaving patterns.

[0132] For example, corresponding payload interleaving patterns can be designed for different PBCH information bit lengths and / or CRC bit lengths. For example, different PBCH information bit lengths and / or CRC bit lengths correspond to different payload interleaving patterns. PBCH information bit lengths can include: 22 bits, 28 bits, 26 bits, 24 bits, 23 bits, 25 bits, and other different information bit lengths. Different information bit lengths correspond to different field pruning scenarios. PBCH CRC bit lengths can include: 24 bits and 16 bits.

[0133] The payload interleaving patterns corresponding to these situations are shown in Tables 1 to 12 above and will not be repeated here.

[0134] Step 503: The UE deinterleaves the payload in the first PBCH according to the first interleaving mode.

[0135] Furthermore, in order to meet more business needs, in some examples, the method of this embodiment may also include: the UE sends a second PBCH on a second frequency band, the payload length in the second PBCH is less than the first threshold, the payload in the second PBCH is interleaved in a second interleaving mode, the bandwidth of the second frequency band is less than the second threshold, and the second frequency band may be the same as or different from the first frequency band.

[0136] The second interleaving mode may be the same as or different from the first interleaving mode. The method for determining the second interleaving mode may refer to the above process and will not be described in detail here. For example, in a sidelink scenario, the UE may serve as a transmitting UE and may transmit a second PBCH on a first frequency band. The payload length in the second PBCH is reduced, and a corresponding payload interleaving mode, i.e., a second interleaving mode, is determined based on the information bit length and / or CRC bit length of the second PBCH. Then, the payload of the second PBCH is interleaved according to the second interleaving mode.

[0137] By applying the communication processing method provided in this embodiment, the UE can deinterleave the payload of the first PBCH with a payload length less than the first threshold according to the newly designed payload interleaving mode corresponding to the first PBCH, that is, the first interleaving mode, so as to meet more communication needs while improving the PBCH transmission performance.

[0138] Figure 6 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to a network device (such as the network device 11 in Figure 1) and may include the following steps.

[0139] Step 601: The network device sends a third PBCH on a third frequency band.

[0140] The payload length of the third PBCH is less than a first threshold, the payload in the third PBCH is not interleaved, and the bandwidth of the third frequency band is less than a second threshold. In some examples, the first threshold may be the payload length of the NR system PBCH, such as the payload length of the existing NR system PBCH. The payload of the third PBCH can be applied to a dedicated spectrum system less than the second threshold. For example, if the second threshold is 5 MHz, the payload of the third PBCH can be applied to a dedicated spectrum system less than 5 MHz.

[0141] For example, for dedicated spectrum with bandwidths less than 5MHz, such as 3MHz and 2.8MHz to 3.6MHz, the channel bandwidth cannot accommodate the entire PBCH. Therefore, the PBCH payload length needs to be reduced. The third PBCH in this embodiment can be a PBCH with a reduced payload length, where the payload length of the third PBCH is less than a certain threshold. Since the traditional PBCH payload interleaving mode is no longer applicable, this embodiment does not consider the payload interleaving of the third PBCH, that is, the payload in the third PBCH is not interleaved. It is then sent to the UE, which receives the third PBCH on the third frequency band.

[0142] By applying the communication processing method provided in this embodiment, the behavior of the base station and the terminal can be clarified, ensuring that the PBCH can be properly processed at both the transmitting and receiving ends.

[0143] Figure 7 shows a flow chart of a communication processing method according to an embodiment of the present disclosure. The method is applied to a UE side (such as UE 12 in Figure 1) and may include the following steps.

[0144] Step 701: The UE receives a third PBCH on a third frequency band.

[0145] The payload length of the third PBCH is less than a first threshold, the payload in the third PBCH is not interleaved, and the bandwidth of the third frequency band is less than a second threshold. In some examples, the first threshold may be the payload length of the NR system PBCH, such as the payload length of the existing NR system PBCH. The payload of the third PBCH can be applied to a dedicated spectrum system less than the second threshold. For example, if the second threshold is 5 MHz, the payload of the third PBCH can be applied to a dedicated spectrum system less than 5 MHz.

[0146] Furthermore, in order to meet more business needs, in some examples, the method of this embodiment may also include: sending a fourth PBCH on a fourth frequency band, the payload length in the fourth PBCH is less than the first threshold, the payload in the fourth PBCH is not interleaved, the bandwidth of the fourth frequency band is less than the second threshold, and the fourth frequency band may be the same as or different from the third frequency band.

[0147] For example, in a sidelink scenario, the UE may function as a transmitting UE and may transmit a fourth PBCH on a fourth frequency band, wherein the payload length of the fourth PBCH is reduced and the payload in the fourth PBCH is not interleaved.

[0148] By applying the communication processing method provided in this embodiment, the behavior of the base station and the terminal can be clarified, ensuring that the PBCH can be properly processed at both the transmitting and receiving ends.
