Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a communication method, apparatus, device and storage medium. Background Technology

[0002] In spectrum scenarios with frequencies less than 5MHz, corresponding research was conducted on supporting new radio (NR) technology in certain dedicated frequency bands. These dedicated spectrums can be used to provide services for specific businesses.

[0003] These dedicated frequency bands only support a subcarrier spacing of 15 kHz, with system bandwidths typically between 5 MHz and 3 MHz. According to NR and Long Term Evolution (LTE) specifications for radio frequency (RF) channels, a 5 MHz system bandwidth can include 25 resource blocks (RBs). According to LTE specifications for RF channels, a 3 MHz system bandwidth can include 15 RBs.

[0004] Currently, in the initial uplink (UL) bandwidth part (BWP), the physical uplink control channel (PUCCH) is configured by default to use frequency hopping for data transmission. Frequency hopping means that for a given time slot in the PUCCH, data transmitted in the first half of the time slot can be transmitted on any physical resource block (PRB) resource in the initial UL BWP, while data transmitted in the second half of the time slot can be transmitted on another PRB resource in the initial UL BWP.

[0005] However, for some of the smaller bandwidths mentioned above, frequency hopping in PUCCH can lead to significant resource waste. Therefore, how to avoid the resource waste caused by frequency hopping in PUCCH is a problem that needs to be solved. Summary of the Invention

[0089] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0090] The communication methods disclosed herein can be applied to Figure 1 The wireless communication system 100 shown may include network device 110 and terminal 120. It is understood that... Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0091] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency-Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and Carrier Sense Multiple Access with Collision Avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G (Generation) networks, 3G networks, 4G networks, or future evolution networks, such as the 5th Generation Wireless Communication System (5G) network. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0092] Furthermore, the network device 110 involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eNB), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, or a transmission point (TP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technologies and device forms used in the embodiments of this disclosure are not limited.

[0093] Furthermore, the terminal 120 involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device.

[0094] In this embodiment, network device 110 and terminal 120 can employ any feasible wireless communication technology to transmit data to each other. The transmission channel corresponding to network device 110 sending data to terminal 120 is called the downlink channel (DL), and the transmission channel corresponding to terminal 120 sending data to network device 110 is called the uplink channel (UL). It is understood that the network device involved in this embodiment can be a base station. Of course, the network device can also be any other possible network device, and the terminal can be any possible terminal; this disclosure does not impose any limitations.

[0095] In spectrum scenarios smaller than 5MHz, R18 investigated supporting NR technology for LTE and certain dedicated spectrum for the Global System for Mobile Communications – Railway (GSM-R). This spectrum primarily serves dedicated communications for power systems and railway systems, as well as public protection and disaster relief services.

[0096] These dedicated frequency bands only support a subcarrier spacing of 15 kHz, and the system bandwidth typically includes 5 MHz and 3 MHz. According to NR and LTE specifications for RF channel bandwidth, a 5 MHz system bandwidth can include 25 RBs. According to LTE specifications for RF channel bandwidth, a 3 MHz system bandwidth can include 15 RBs.

[0097] In the current NR protocol, the PUCCH on the initial UL BWP can be used at least for the hybrid automatic repeat request (HARQ) feedback of message 4 (Msg.4) in a 4-step random access process, or for the HARQ feedback of message B (Msg.B) in a 2-step random access process. The physical resources of the PUCCH are configured based on broadcast messages. The protocol predefines a set of possible resource configurations for this PUCCH, as shown in Table 1.

[0098]

[0099] Table 1

[0100] in, This represents the number of PRBs in the initial UL BWP. The PUCCH resource configuration set shown in Table 1 above includes the PUCCH transmission format, the orthogonal frequency division multiplexing (OFDM) symbol resources occupied in the time domain, the PRB resource parameters in the initial UL BWP, and the cyclic shift (CS) sequence parameters for PUCCH multiplexing within a PRB. The OFDM symbol resources occupied in the time domain may include, for example, the first symbol and the number of symbols occupied. PRB resource parameters may include, for example, the PRB offset.

[0101] Each row in Table 1 represents a resource configuration set and corresponds to an index. Network devices can notify this index through system information block (SIB) messages. Terminals can use this index and the preset information in Table 1 to determine the PUCCH-related transmission configuration.

[0102] Meanwhile, the PUCCH configured in the initial UL BWP uses frequency hopping for data transmission by default. Frequency hopping (also known as frequency-hopping transmission) means that for a given time slot in the PUCCH, data transmitted in the first half of the time slot can be transmitted on any PRB resource in the initial UL BWP, and data transmitted in the second half of the time slot can be transmitted on another PRB resource in the initial UL BWP.

[0103] For example, if satisfying Then the PRB index corresponding to the PRB where the first hop of the PUCCH is located can be... The PRB index corresponding to the PRB where the second hop is located can be The corresponding cyclic shift sequence can be .

[0104] For example, if the following conditions are met Then the PRB index corresponding to the PRB where the first hop of the PUCCH is located can be... The PRB index corresponding to the PRB where the second hop is located can be The corresponding cyclic shift sequence can be .

[0105] in, This represents the PUCCH resource index calculated by the terminal based on scheduling information. It can be understood that... This is not the same index as the index in the first column of Table 1. This is represented as PRB offset, and its value can be found in the "PRB Offset" column of Table 1. This indicates the number of indices in the cyclic shift sequence. `mod` represents the modulo operation.

[0106] However, for the aforementioned smaller bandwidths, the frequency hopping gain achievable through PUCCH frequency hopping is quite limited. It's understandable that the wider the bandwidth, the higher the frequency hopping gain from PUCCH frequency hopping. Furthermore, if PUCCH frequency hopping is used, there will be significant resource waste when the number of terminals in the cell is small. This resource waste will have a more severe impact on scheduling in low-bandwidth scenarios.

[0107] Therefore, how to avoid the waste of resources caused by frequency hopping of PUCCH is a problem that needs to be solved.

[0108] This disclosure provides a communication method that determines the PUCCH transmission mode during the random access phase, allowing for the selection of frequency-hopping or non-frequency-hopping transmission based on the PUCCH transmission mode. This avoids the resource waste caused by using PUCCH frequency hopping.

[0109] Figure 2 This is a flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 2 As shown, the method is applied to a terminal and may include the following steps:

[0110] In step S11, in response to the terminal's operating frequency band meeting the conditions and the terminal performing PUCCH transmission based on the operating frequency band during the random access phase, the transmission mode of PUCCH is determined.

[0111] In some embodiments, the terminal's operating frequency band may meet certain conditions, such as pre-defined operating frequency band conditions. In response to the terminal's operating frequency band meeting these conditions, the terminal performs PUCCH transmission based on the operating frequency band during the random access phase, determining the PUCCH transmission mode. The PUCCH transmission mode may include frequency hopping transmission or non-frequency hopping transmission.

[0112] For example, the terminal's operating frequency band can meet the pre-set operating frequency band conditions. Furthermore, during the random access phase, the terminal transmits PUCCH based on the operating frequency band, and the terminal can determine that the PUCCH transmission mode is frequency hopping transmission.

[0113] For example, the terminal's operating frequency band can meet the preset operating frequency band conditions. Furthermore, during the random access phase, the terminal transmits PUCCH based on the operating frequency band, and the terminal can determine that the PUCCH transmission mode is non-frequency hopping transmission.

[0114] It is understandable that non-frequency hopping transmission means that frequency hopping is not performed during transmission, or that it is not frequency hopping transmission.

[0115] In step S12, a random access procedure is performed based on the determined PUCCH transmission mode.

[0116] In some embodiments, the terminal may perform a random access procedure based on the PUCCH transmission method determined in S11.

[0117] For example, a random access procedure using a defined PUCCH transmission method may include using the PUCCH to carry the HARQ feedback for Msg.4 in a 4-step random access procedure, or using the PUCCH to carry the HARQ feedback in a 2-step random access procedure.

[0118] This disclosure determines the PUCCH transmission mode during the random access phase in a suitable operating frequency band, allowing for the selection of frequency-hopping or non-frequency-hopping transmission based on the PUCCH transmission mode. This avoids the resource waste caused by using PUCCH frequency hopping.

[0119] In the communication method provided in the embodiments of this disclosure Figure 3 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 3 As shown, the random access process in S12, based on the determined PUCCH transmission mode, may include the following steps:

[0120] In step S21, in response to the PUCCH transmission mode being non-frequency hopping transmission, the PUCCH PRB index is determined based on at least one of the following: PUCCH resource index, uplink partial bandwidth (BWP) resource amount, cyclic shift sequence number, and PUCCH physical resource block (PRB) parameters.

[0121] In some embodiments, in response to the PUCCH transmission method being non-frequency hopping transmission, the terminal can determine the PUCCH PRB index based on at least one of the PUCCH resource index, the number of uplink BWP resource cyclic shift sequences, and the PUCCH PRB parameters.

[0122] In step S22, a random access procedure is performed on the PRB corresponding to the PRB index.

[0123] In some embodiments, the terminal performs a random access procedure on the PRB corresponding to the PRB index determined in S21.

[0124] When the PUCCH transmission mode adopts non-frequency hopping transmission, this disclosure can determine the PRB index through the PUCCH resource index, the number of uplink BWP resource cyclic shift sequences, and PUCCH PRB parameters, so that the terminal can use non-frequency hopping transmission for random access, avoiding the resource waste caused by PUCCH frequency hopping.

[0125] In the communication method provided in this embodiment, the PUCCH resource index is determined based on the parameters of the physical downlink control channel (PDCCH) used in the random access procedure.

[0126] In some embodiments, the PUCCH resource index can be determined by the relevant parameters of the PDCCH of the scheduling data.

[0127] This disclosure determines the PUCCH resource index through relevant parameters of the PDCCH, so as to determine the PRB index based on the PUCCH resource index, enabling the terminal to use non-frequency hopping transmission for random access procedures, thus avoiding the resource waste caused by using PUCCH frequency hopping.

[0128] In the communication method provided in this disclosure, the parameters of the PDCCH may include at least one of the following: control channel element (CCE) information occupied by the PDCCH; and PUCCH resource allocation information contained in the PDCCH.

[0129] In some embodiments, the parameters of the PDCCH may include control channel element (CCE) information occupied by the PDCCH.

[0130] For example, the terminal can determine the PUCCH resource index based on the CCE information occupied by the PDCCH.

[0131] In some embodiments, the parameters of the PDCCH may include PUCCH resource allocation information contained in the PDCCH.

[0132] For example, the terminal can determine the PUCCH resource index based on the PUCCH resource allocation information contained in the PDCCH.

[0133] In some embodiments, the parameters of the PDCCH may include: CCE information occupied by the PDCCH, and PUCCH resource allocation information contained in the PDCCH.

[0134] For example, the terminal can determine the PUCCH resource index based on the CCE information occupied by the PDCCH and the PUCCH resource allocation information contained in the PDCCH.

[0135] This disclosure determines the PUCCH resource index by using the CCE information occupied by the PDCCH and / or the PUCCH resource allocation information contained in the PDCCH. This allows the PRB index to be determined based on the PUCCH resource index, enabling the terminal to perform random access procedures using non-frequency hopping transmission, thus avoiding the resource waste caused by PUCCH frequency hopping.

[0136] In the communication method provided in this disclosure, one or more of the uplink BWP resource quantity, the number of cyclic shift sequences, and the PUCCHPRB parameter are configured based on higher-layer signaling sent by the network device.

[0137] In some embodiments, the uplink BWP resource volume can be configured by higher-layer signaling sent by the network device.

[0138] In some embodiments, the number of cyclic shift sequences can be configured by higher-layer signaling sent by the network device.

[0139] In some embodiments, the PUCCH PRB parameter can be configured by higher-layer signaling sent by the network device.

[0140] In some embodiments, higher-layer signaling can be configured based on the parameters shown in Table 1.

[0141] In some embodiments, higher-layer signaling can be configured based on the parameters shown in Table 2.

[0142]

[0143] Table 2

[0144] As can be seen, Table 2 is similar to Table 1, but the number of PUCCH resource configuration sets in Table 2 is less than that in Table 1. In other words, this disclosure also provides another possible set of PUCCH configurations. The specific parameters in Table 2 are only one possible example; the core purpose is to reduce the number of PUCCH resource configuration sets in Table 1. A portion of these sets is selected as the new possible set of PUCCH resource configurations.

[0145] Of course, Table 2 can be any subset of the PUCCH resource configuration sets in Table 1. Any number of PUCCH resource configuration sets can be selected as the new possible PUCCH resource configuration set according to the actual situation. In some embodiments, a subset of PUCCH resource configuration sets with PRB offset 0 can be selected as the new possible PUCCH resource configuration set. This disclosure does not impose any limitations.

[0146] It is understood that this disclosure provides the possible resource configuration set of PUCCH shown in Table 2, taking into account the need to reduce the computational complexity of determining the PRB index and alleviate the complexity of PUCCH resource configuration during actual operation. Therefore, a smaller set of PUCCH resource configurations can be used to determine the PRB index in the case of non-frequency hopping transmission.

[0147] This disclosure configures one or more of the following parameters—uplink BWP resource quantity, cyclic shift sequence quantity, and PUCCH PRB parameters—using higher-layer signaling to determine the PRB index. This allows the terminal to perform random access procedures using non-frequency hopping transmission, avoiding the resource waste caused by PUCCH frequency hopping.

[0148] In the communication method provided in the embodiments of this disclosure Figure 4 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 4 As shown, determining the PUCCH PRB index in S21 based on at least one of the following: PUCCH resource index, uplink bandwidth portion BWP resource amount, cyclic shift sequence number, and PUCCH physical resource block PRB parameters, may include the following steps:

[0149] In step S31, the first PRB index is determined based on the PUCCH resource index, the number of cyclic shift sequences, and the PUCCH PRB parameters.

[0150] In some embodiments, the terminal may determine the first PRB index based on the PUCCH resource index, the number of cyclic shift sequences, and the PUCCH PRB parameters.

[0151] For example, the terminal can determine the first PRB index in the manner shown in Formula 1.

[0152]

[0153] ...Formula 1

[0154] in, This indicates the PUCCH resource index. Indicates the number of cyclic shift sequences. This indicates the PRB offset in the PUCCH PRB parameter.

[0155] This disclosure allows the PRB index to be determined using the PUCCH resource index, the number of cyclic shift sequences, and the PUCCH PRB parameters. This enables the terminal to perform random access procedures using non-frequency hopping transmission, avoiding the resource waste caused by using PUCCH frequency hopping.

[0156] In the communication method provided in the embodiments of this disclosure Figure 5 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 5 As shown, determining the PUCCH PRB index in S21 based on at least one of the following: PUCCH resource index, uplink bandwidth portion BWP resource amount, cyclic shift sequence number, and PUCCH physical resource block PRB parameters, may include the following steps:

[0157] In step S41, the second PRB index is determined based on the PUCCH resource index, the uplink BWP resource quantity, the number of cyclic shift sequences, and the PUCCHPRB parameter.

[0158] In some embodiments, the terminal may determine the second PRB index based on the PUCCH resource index, the uplink BWP resource amount, the number of cyclic shift sequences, and the PUCCH PRB parameters.

[0159] For example, the terminal can determine the second PRB index in the manner shown in Formula 2.

[0160]

[0161] ...Formula 2

[0162] in, This represents the amount of uplink BWP resources, such as the number of PRBs in the initial UL BWP.

[0163] This disclosure allows the PRB index to be determined using the PUCCH resource index, uplink BWP resource quantity, cyclic shift sequence number, and PUCCH PRB parameters. This enables the terminal to perform random access procedures using non-frequency hopping transmission, avoiding the resource waste caused by using PUCCH frequency hopping.

[0164] In the communication method provided in the embodiments of this disclosure Figure 6This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 6 As shown, the random access procedure performed on the PRB corresponding to the PRB index in S22 may include the following steps:

[0165] In step S51, the index of the cyclic shift sequence is determined based on the PUCCH resource index and the number of cyclic shift sequences.

[0166] In some embodiments, the terminal can determine the index of the cyclic shift sequence based on the PUCCH resource index and the number of cyclic shift sequences. The cyclic shift sequence corresponding to the index of the cyclic shift sequence is used to reuse the PRB corresponding to the PRB index.

[0167] For example, the terminal can be based on and Determine the index of the cyclic shift sequence.

[0168] In step S52, the PRB corresponding to the PRB index is reused during the random access process using the cyclic shift sequence corresponding to the index of the cyclic shift sequence.

[0169] In some embodiments, the terminal can use the cyclic shift sequence corresponding to the index of the cyclic shift sequence determined in step S51 to reuse the PRB corresponding to the PRB index during the random access procedure. It is understood that PRB multiplexing can be based on the code domain, making the multiplexed PRBs orthogonal and avoiding signal interference.

[0170] This disclosure enables the reuse of the PRB by determining the index of the cyclic shift sequence. This allows the terminal to perform random access procedures using non-frequency hopping transmission, avoiding the resource waste caused by using PUCCH frequency hopping.

[0171] In the communication method provided in this embodiment, the index of the cyclic shift sequence is the modulus of the PUCCH resource index and the number of cyclic shift sequences.

[0172] In some embodiments, the terminal can determine the index of the cyclic shift sequence by using the PUCCH resource index and the modulus of the number of cyclic shift sequences. For example, it can be determined using Equation 3.

[0173]

[0174] ...Formula 3

[0175] It's understandable that `mod` represents the modulo operation. That is, it determines... Divide by The remainder is used as the index of the cyclic shift sequence.

[0176] This disclosure determines the index of the cyclic shift sequence by modulo operation to achieve PRB reuse. This allows the terminal to perform random access procedures using non-frequency hopping transmission, avoiding the resource waste caused by using PUCCH frequency hopping.

[0177] In the communication method provided in the embodiments of this disclosure Figure 7 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 7 As shown, determining the transmission mode of PUCCH in S11 may include the following steps:

[0178] In step S61, frequency hopping indication information sent by the network device is received.

[0179] In some embodiments, the terminal may receive frequency hopping indication information sent by the network device. This frequency hopping indication information is used to indicate whether the PUCCH transmission mode is frequency hopping or non-frequency hopping.

[0180] For example, a terminal can receive system messages sent by a network device, which carry frequency hopping indication information. This frequency hopping indication information can notify whether the PUCCH transmission mode during random access is frequency hopping or non-frequency hopping.

[0181] In step S62, the transmission mode of PUCCH is determined based on the frequency hopping indication information.

[0182] In some embodiments, the terminal can determine the transmission mode of PUCCH based on the frequency hopping indication information received in S61.

[0183] For example, if the frequency hopping indication information indicates that the PUCCH transmission mode is frequency hopping transmission, then the terminal determines that the PUCCH transmission mode is frequency hopping transmission; conversely, if the frequency hopping indication information indicates that the PUCCH transmission mode is non-frequency hopping transmission, then the terminal determines that the PUCCH transmission mode is non-frequency hopping transmission.

[0184] This disclosure allows network devices to send frequency hopping indication information to indicate whether the PUCCH transmission mode is frequency hopping or non-frequency hopping, enabling terminals to flexibly use non-frequency hopping transmission for random access procedures and avoiding resource waste caused by using PUCCH frequency hopping.

[0185] In the communication method provided in this embodiment, the frequency hopping indication information includes a PRB index indicator. The PRB index indicator is used to indicate whether the PRB used in the random access procedure corresponds to a first PRB index or a second PRB index.

[0186] In some embodiments, the frequency hopping indication information may include a PRB index indicator. This PRB index indicator can be used to indicate whether the PRB used during the random access procedure corresponds to a first PRB index or a second PRB index.

[0187] For example, when the PRB index indicator is a first preset value, it can indicate that the PRB used during the random access procedure is the PRB corresponding to the first PRB index. The first PRB index can be determined using the method shown in Formula 1, and during the random access procedure, the corresponding PRB can be found using the first PRB index to perform the random access procedure.

[0188] For example, when the PRB index indicator is the second preset value, it can indicate that the PRB used during the random access procedure is the PRB corresponding to the second PRB index. The second PRB index can be determined using the method shown in Formula 2, and during the random access procedure, the corresponding PRB can be found using the second PRB index to perform the random access procedure.

[0189] This disclosure indicates the PRB used during random access by using a PRB index indicator, enabling the terminal to perform random access using non-frequency hopping transmission, thus avoiding the resource waste caused by using PUCCH frequency hopping.

[0190] In the communication method provided in the embodiments of this disclosure Figure 8 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 8 As shown, determining the transmission mode of PUCCH in S11 may include the following steps:

[0191] In step S71, the transmission method of PUCCH is determined based on predefined rules.

[0192] In some embodiments, the terminal may determine the transmission method of PUCCH based on predefined rules.

[0193] For example, the PUCCH transmission method during a terminal's random access procedure is predefined. This could be frequency hopping or non-frequency hopping transmission. The terminal determines the PUCCH transmission method based on the predefined PUCCH transmission method.

[0194] This disclosure allows the PUCCH transmission mode to be determined by predefined rules, either frequency hopping or non-frequency hopping, enabling the terminal to use non-frequency hopping for random access procedures and avoiding the resource waste caused by using PUCCH frequency hopping.

[0195] In the communication method provided in this embodiment, the PUCCH transmission mode is non-frequency hopping transmission by default.

[0196] In some embodiments, when a terminal performs a random access procedure, the PUCCH transmission mode can be set to non-frequency hopping transmission by default.

[0197] For example, a terminal can use the default PUCCH transmission method (non-frequency hopping transmission) for random access based on predefined rules. Alternatively, if the terminal does not receive a frequency hopping indication from the network device, it can also use the default PUCCH transmission method (non-frequency hopping transmission) for random access.

[0198] This disclosure allows terminals to perform random access procedures using non-frequency hopping transmission by defaulting to PUCCH transmission mode, thus avoiding the resource waste caused by PUCCH frequency hopping.

[0199] In the communication method provided in this embodiment, the working frequency band meeting the conditions may include at least one of the following: the working frequency band number is n8; the working frequency band number is n26; the working frequency band number is n28; the working frequency band number is n100.

[0200] In some embodiments, the operating frequency band on which the terminal of this disclosure performs the random access process may be the operating frequency band corresponding to frequency band number n8.

[0201] In some embodiments, the operating frequency band on which the terminal of this disclosure performs the random access process may be the operating frequency band corresponding to frequency band number n26.

[0202] In some embodiments, the operating frequency band on which the terminal of this disclosure performs the random access process may be the operating frequency band corresponding to frequency band number n28.

[0203] In some embodiments, the operating frequency band on which the terminal of this disclosure performs the random access process may be the operating frequency band corresponding to frequency band number n100.

[0204] It is understood that the above is merely an exemplary description. The operating frequency band used by the PUCCH during the random access procedure can also be any frequency band numbered in this disclosure. The specific selection can be made according to the actual situation, and this disclosure does not impose any limitations.

[0205] This disclosure allows for determining whether the PUCCH transmission mode is frequency hopping or non-frequency hopping during random access procedures in certain specific operating frequency bands. This enables the terminal to use non-frequency hopping transmission for random access procedures, avoiding the resource waste caused by using PUCCH frequency hopping.

[0206] Based on the same concept, this disclosure also provides a communication method applied to the network device side.

[0207] Figure 9 This is a flowchart illustrating another communication method according to an exemplary embodiment, such as... Figure 9 As shown, the method is applied to network devices and may include the following steps:

[0208] In step S81, in response to the terminal's operating frequency band meeting the conditions, the transmission mode of the PUCCH for the terminal to transmit the Physical Uplink Control Channel (PUCCH) based on the operating frequency band during the random access phase is configured.

[0209] In some embodiments, the network device can configure the PUCCH transmission mode. The network device can respond to conditions met by the terminal's operating frequency band, such as pre-defined operating frequency band conditions. The network device configures the PUCCH transmission mode for the terminal during the random access phase, based on the operating frequency band. The PUCCH transmission mode includes frequency hopping transmission or non-frequency hopping transmission.

[0210] For example, in response to the terminal's operating frequency band meeting the conditions, the network device configures the terminal to use frequency hopping transmission for PUCCH transmission based on the operating frequency band during the random access phase.

[0211] For example, in response to the terminal's operating frequency band meeting the requirements, the network device configures the terminal to use non-frequency hopping transmission for PUCCH transmission based on the operating frequency band during the random access phase.

[0212] It is understandable that non-frequency hopping transmission means that frequency hopping is not performed during transmission, or that it is not frequency hopping transmission.

[0213] In step S82, a random access process is performed with the terminal based on the PUCCH transmission method.

[0214] In some embodiments, the network device may perform a random access procedure with the terminal based on the PUCCH transmission mode configured in S81.

[0215] For example, the random access process between a network device and a terminal based on the PUCCH transmission method may include the PUCCH being used to carry the HARQ feedback of Msg.4 in a 4-step random access, or the PUCCH being used to carry the HARQ feedback in a 2-step random access.

[0216] This disclosure determines the PUCCH transmission mode during the random access phase in a suitable operating frequency band, allowing for the selection of frequency-hopping or non-frequency-hopping transmission based on the PUCCH transmission mode. This avoids the resource waste caused by using PUCCH frequency hopping.

[0217] In the communication method provided in the embodiments of this disclosure Figure 10This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 10 As shown, the random access process between the terminal and the PUCCH-based transmission method in S82 may include the following steps:

[0218] In step S91, in response to the PUCCH transmission mode being non-frequency hopping transmission, the PUCCH PRB index is determined based on at least one of the following: PUCCH resource index, uplink bandwidth (BWP) resource amount, cyclic shift sequence number, and PUCCH physical resource block (PRB) parameters.

[0219] In some embodiments, in response to the PUCCH transmission method being non-frequency hopping transmission, the network device can determine the PUCCH PRB index based on at least one of the PUCCH resource index, the number of uplink BWP resource cyclic shift sequences, and the PUCCH PRB parameters.

[0220] In step S92, a random access procedure is performed with the terminal on the PRB corresponding to the PRB index.

[0221] In some embodiments, the network device performs a random access procedure with the terminal on the PRB corresponding to the PRB index determined in S91.

[0222] When the PUCCH transmission mode adopts non-frequency hopping transmission, this disclosure can determine the PRB index through the PUCCH resource index, the number of uplink BWP resource cyclic shift sequences, and PUCCH PRB parameters, so that the network device can use non-frequency hopping transmission to perform random access with the terminal, avoiding the resource waste caused by using PUCCH frequency hopping.

[0223] In the communication method provided in this disclosure, the PUCCH resource index is determined based on the parameters of the PDCCH used in the random access procedure.

[0224] In some embodiments, the PUCCH resource index can be determined by the relevant parameters of the PDCCH of the scheduling data.

[0225] This disclosure determines the PUCCH resource index through relevant parameters of the PDCCH, so as to determine the PRB index based on the PUCCH resource index, enabling the terminal to use non-frequency hopping transmission to perform random access procedures with the terminal, thus avoiding the resource waste caused by using PUCCH frequency hopping.

[0226] In the communication method provided in this disclosure, the parameters of the PDCCH may include at least one of the following: control channel element (CCE) information occupied by the PDCCH; and PUCCH resource allocation information contained in the PDCCH.

[0227] In some embodiments, the parameters of the PDCCH may include CCE information occupied by the PDCCH.

[0228] For example, network devices can determine the PUCCH resource index based on the CCE information occupied by the PDCCH.

[0229] In some embodiments, the parameters of the PDCCH may include PUCCH resource allocation information contained in the PDCCH.

[0230] For example, network devices can determine the PUCCH resource index based on the PUCCH resource allocation information contained in the PDCCH.

[0231] In some embodiments, the parameters of the PDCCH may include: CCE information occupied by the PDCCH, and PUCCH resource allocation information contained in the PDCCH.

[0232] For example, network devices can determine the PUCCH resource index based on the CCE information occupied by the PDCCH and the PUCCH resource allocation information contained in the PDCCH.

[0233] This disclosure determines the PUCCH resource index by using the CCE information occupied by the PDCCH and / or the PUCCH resource allocation information contained in the PDCCH. This allows for the determination of the PRB index based on the PUCCH resource index, enabling network devices to use non-frequency hopping transmission for random access procedures with terminals, thus avoiding the resource waste caused by PUCCH frequency hopping.

[0234] In the communication method provided in this disclosure, one or more of the uplink BWP resource quantity, the number of cyclic shift sequences, and the PUCCHPRB parameter are configured based on the higher-layer signaling of the network device.

[0235] In some embodiments, the uplink BWP resource volume can be configured by higher-layer signaling of the network device.

[0236] In some embodiments, the number of cyclic shift sequences can be configured by higher-layer signaling of the network device.

[0237] In some embodiments, the PUCCH PRB parameter can be configured by higher-layer signaling of the network device.

[0238] In some embodiments, higher-layer signaling can be configured based on the parameters shown in Table 1.

[0239] In some embodiments, higher-layer signaling can be configured based on the parameters shown in Table 2.

[0240] This disclosure configures one or more of the following parameters via higher-layer signaling: uplink BWP resource quantity, number of cyclic shift sequences, and PUCCH PRB parameters, to determine the PRB index. This allows network devices to use non-frequency hopping transmission for random access procedures with terminals, avoiding the resource waste caused by using PUCCH frequency hopping.

For example...

[0242] In step S101, the first PRB index is determined based on the PUCCH resource index, the number of cyclic shift sequences, and the PUCCH PRB parameters.

[0243] In some embodiments, the network device may determine the first PRB index based on the PUCCH resource index, the number of cyclic shift sequences, and the PUCCHHPRB parameter.

[0244] For example, a network device can determine the first PRB index in the manner shown in Formula 1.

[0245] This disclosure allows the PRB index to be determined using the PUCCH resource index, the number of cyclic shift sequences, and the PUCCH PRB parameters. This enables network devices to use non-frequency hopping transmission for random access procedures with terminals, avoiding the resource waste caused by using PUCCH frequency hopping.

[0248] In some embodiments, the network device may determine the second PRB index based on the PUCCH resource index, the uplink BWP resource amount, the number of cyclic shift sequences, and the PUCCH PRB parameters.

[0249] For example, network devices can determine the second PRB index in the manner shown in Formula 2.

[0250] This disclosure allows the determination of the PRB index using the PUCCH resource index, uplink BWP resource quantity, cyclic shift sequence quantity, and PUCCH PRB parameters. This enables network devices to use non-frequency hopping transmission for random access procedures with terminals, avoiding the resource waste caused by PUCCH frequency hopping.

[0251] In the communication method provided in the embodiments of this disclosure Figure 13 This is a flowchart illustrating yet another communication method according to an exemplary embodiment. For example... Figure 13 As shown, the random access process with the terminal on the PRB corresponding to the PRB index in S92 may include the following steps:

[0252] In step S121, the index of the cyclic shift sequence is determined based on the PUCCH resource index and the number of cyclic shift sequences.

[0253] In some embodiments, the network device can determine the index of the cyclic shift sequence based on the PUCCH resource index and the number of cyclic shift sequences. The cyclic shift sequence corresponding to the index of the cyclic shift sequence is used to reuse the PRB corresponding to the PRB index.

[0254] For example, network devices can be based on and Determine the index of the cyclic shift sequence.

[0255] In step S122, the PRB corresponding to the PRB index is reused during the random access process using the cyclic shift sequence corresponding to the index of the cyclic shift sequence.

[0256] In some embodiments, the network device can utilize the cyclic shift sequence corresponding to the index of the cyclic shift sequence determined in step S121 to reuse the PRB corresponding to the PRB index during the random access procedure. It is understood that PRB multiplexing can be based on the code domain, ensuring that the multiplexed PRBs are orthogonal and avoiding signal interference.

[0257] This disclosure enables the reuse of the PRB by determining the index of the cyclic shift sequence. This allows network devices to use non-frequency hopping transmission for random access procedures with terminals, avoiding the resource waste caused by using PUCCH frequency hopping.

[0258] In the communication method provided in this embodiment, the index of the cyclic shift sequence is the modulus of the PUCCH resource index and the number of cyclic shift sequences.

[0259] In some embodiments, the network device can determine the index of the cyclic shift sequence by using the PUCCH resource index and the modulus of the number of cyclic shift sequences. For example, it can be determined using Equation 3.

[0260] This disclosure determines the index of the cyclic shift sequence by modulo operation to achieve PRB reuse. This allows network devices to use non-frequency hopping transmission for random access procedures with terminals, avoiding the resource waste caused by using PUCCH frequency hopping.

[0261] In the communication method provided in the embodiments of this disclosure Figure 14 This is a flowchart illustrating another communication method according to an exemplary embodiment. For example... Figure 14 As shown, the method may also include the following steps:

[0262] In step S131, frequency hopping indication information is sent to the terminal.

[0263] In some embodiments, the network device may send frequency hopping indication information to the terminal. This frequency hopping indication information is used to indicate whether the PUCCH transmission mode is frequency hopping or non-frequency hopping.

[0264] For example, a network device can send a system message to a terminal, which carries frequency hopping indication information. This frequency hopping indication information can notify whether the PUCCH transmission mode during random access is frequency hopping or non-frequency hopping. This allows the terminal to determine whether the PUCCH transmission mode is frequency hopping or non-frequency hopping based on the received frequency hopping indication information.

[0265] This disclosure allows network devices to send frequency hopping indication information to indicate whether the PUCCH transmission mode is frequency hopping or non-frequency hopping. Non-frequency hopping transmission can be flexibly configured for random access procedures, avoiding the resource waste caused by using PUCCH frequency hopping.

[0266] In the communication method provided in this embodiment, the frequency hopping indication information includes a PRB index indicator. The PRB index indicator is used to indicate whether the PRB used in the random access procedure corresponds to a first PRB index or a second PRB index.

[0267] In some embodiments, the frequency hopping indication information may include a PRB index indicator. This PRB index indicator can be used to indicate whether the PRB used during the random access procedure corresponds to a first PRB index or a second PRB index.

[0268] For example, when the PRB index indicator is a first preset value, it can indicate that the PRB used during the random access procedure is the PRB corresponding to the first PRB index. The first PRB index can be determined using the method shown in Formula 1, and during the random access procedure, the corresponding PRB can be found using the first PRB index to perform the random access procedure.

[0269] For example, when the PRB index indicator is the second preset value, it can indicate that the PRB used during the random access procedure is the PRB corresponding to the second PRB index. The second PRB index can be determined using the method shown in Formula 2, and during the random access procedure, the corresponding PRB can be found using the second PRB index to perform the random access procedure.

[0270] This disclosure indicates the PRB used during random access by using a PRB index indicator, enabling network devices to use non-frequency hopping transmission for random access with terminals, thus avoiding the resource waste caused by using PUCCH frequency hopping.

For example... Figure 15 As shown, the PUCCH transmission method configured in S81 for the terminal to transmit the Physical Uplink Control Channel (PUCCH) based on the operating frequency band during the random access phase may include the following steps:

[0272] In step S141, the transmission mode of PUCCH is configured based on predefined rules.

[0273] In some embodiments, network devices can configure the transmission method of PUCCH based on predefined rules.

[0274] For example, the PUCCH transmission method during a terminal's random access procedure is predefined. This could be frequency hopping or non-frequency hopping transmission. The network device configures the PUCCH transmission method based on the predefined transmission method.

[0275] This disclosure allows for the configuration of PUCCH transmission mode as either frequency hopping or non-frequency hopping via predefined rules. This enables network devices to use non-frequency hopping transmission for random access with terminals, avoiding the resource waste caused by using PUCCH frequency hopping.

[0278] For example, network devices can use the default PUCCH transmission method, i.e., non-frequency hopping transmission, to perform a random access procedure with the terminal based on predefined rules. As another example, when a network device does not send frequency hopping indication information, it uses the default PUCCH transmission method, i.e., non-frequency hopping transmission, to perform a random access procedure with the terminal.

[0284] In some embodiments, the operating frequency band on which the terminal of this disclosure performs the random access process may be the operating frequency band corresponding to frequency band number n100.

[0285] It is understood that the above is merely an exemplary description. The operating frequency band used by the PUCCH during the random access procedure can also be any frequency band numbered in this disclosure. The specific selection can be made according to the actual situation, and this disclosure does not impose any limitations.
