[0137] Figure 1 is a schematic diagram of the architecture of a communication system provided according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0138] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0139] In some embodiments, network device 102 may include at least one of the following: access network device, core network element.

[0140] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. In some embodiments, the access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0141] In some embodiments, the technical solutions of this disclosure can be applied to Open Radio Access Network (Open RAN) architectures. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0142] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0143] In some embodiments, a core network element can be a single device, multiple devices, or a group of devices. The element can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0144] In some embodiments, the communication system 100 described above may be a 4G communication system or a 5G communication system. It should be noted that the communication system 100 may also be other communication systems, such as a 6G communication system, but this disclosure does not specifically limit it.

[0145] In a communication system, a wireless signal between a base station and a terminal may travel from the transmitter to the receiver via multiple paths. Because these paths may have different lengths and may be affected by factors such as environment, terrain, and clutter, the wireless signal on each path may arrive at the receiver with different transmission delays. This results in a delay spread in the time domain. Such delay spread can also be referred to as multipath delay spread. In some embodiments, the delay spread caused by multiple paths can be measured as the difference between the maximum transmission delay corresponding to the longest path and the minimum transmission delay corresponding to the shortest path.

[0146] In some cases, the delay of wireless signals can vary with changes in environment, terrain, and clutter, and there is no strict mapping relationship with the cell radius.

[0147] In some cases, multipath delay spread can lead to two types of interference: inter-symbol interference (ISI) and inter-channel interference (ICI). ISI can affect the transmission quality of digital signals. ICI can disrupt the orthogonality of subcarriers in orthogonal frequency division multiplexing (OFDM) systems, thus affecting the receiver's demodulation of radio signals.

[0148] In some embodiments, to reduce or eliminate the impact of inter-symbol interference and inter-channel interference on the transmission quality of wireless signals, a CP can be introduced as a prefix for the symbol. At the receiver, the receiver can be configured to counteract the effects of multipath delay spread by discarding the CP.

[0149] In some embodiments, taking a 5G system as an example, CPs can be divided into two categories: normal CP (NCP) and extended CP (ECP). In some embodiments, the duration of ECP can be longer than that of NCP, and therefore it can more effectively reduce or eliminate ISI and ICI compared to NCP.

[0150] In some embodiments, one or more time slot configuration patterns (TDD-UL-DL-Pattern) can be configured within a time slot configuration cycle (TDD-UL-DL-ConfigCommon). In some embodiments, within a time slot configuration pattern, one or more symbol classes contained in a time slot can be configured.

[0151] In some embodiments, one or more slot configuration modes can be configured within TDD-UL-DL-ConfigDedicated. In some embodiments, within a slot configuration mode, one or more symbol classes contained in a slot can be configured. In some embodiments, TDD-UL-DL-ConfigDedicated can be used to configure symbol classes for symbols configured as flexible symbols by TDD-UL-DL-ConfigCommon.

[0152] In some embodiments, the symbol classes contained in one or more time slots may be indicated in the downlink control information (DCI). In one example, the symbol classes contained in one or more time slots may be indicated in DCI format 2-0. In some embodiments, the DCI may be used to configure the symbol classes of symbols configured as flexible by TDD-UL-DL-ConfigDedicated.

[0153] In some embodiments, symbol classes can be configured within a carrier band and / or bandwidth part (BWP). In some embodiments, symbol classes can be configured for a BWP. In some embodiments, a BWP can be configured to use the same symbol class. For example, within a BWP, all symbols in a slot configuration period can be configured to have the same symbol class.

[0154] In some embodiments, the symbol category may include: symbols using NCP and symbols using ECP.

[0155] Therefore, how to achieve flexible configuration of CP length to adapt to a wide variety of business types is an urgent problem to be solved.

[0156] Figure 2 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 2, the communication method of this embodiment includes steps S201 to S202.

[0157] In step S201, network device 102 sends first information to terminal 101.

[0158] In some embodiments, network device 102 may send first information.

[0159] In some embodiments, terminal 101 may receive first information.

[0160] In some embodiments, the first information can be used to determine the CP length configuration. In some embodiments, the first information can be used by terminal 101 to determine the CP length configuration.

[0161] In some embodiments, the name of the first information is not limited, and it may be, for example, CP configuration information, CP indication information, CP length information, etc.

[0162] In some embodiments, the first information may be used by terminal 101 to determine the time-domain and / or frequency-domain position of at least one second time unit within the first unit. In some embodiments, the CP length configuration may include the time-domain position of the second time unit corresponding to one or more CP lengths within the first time unit. In some embodiments, the CP length configuration may include the frequency-domain position of the second time unit corresponding to one or more CP lengths within the first time unit.

[0163] In some embodiments, the first time unit may include at least one second time unit. For example, the first time unit may include one second time unit. For example, the first time unit may include multiple second time units.

[0164] In some embodiments, at least one second time unit in the first time unit may correspond to at least one CP length. In one example, at least one second time unit in the first time unit may correspond to the same CP length. In one example, at least one second time unit in the first time unit may correspond to two or more CP lengths.

[0165] In some embodiments, the first information can be used to determine the temporal location of the third time unit within the first time unit. In some embodiments, the third time unit can be a second time unit corresponding to the length of the first CP among at least one second time unit. In other words, at least a portion of the second time units in at least one second time unit in the first time unit correspond to the length of the first CP.

[0166] In some embodiments, the first CP length may be one of at least one CP lengths corresponding to at least one second time unit in the first time unit. In some embodiments, the first CP length may belong to at least one CP length corresponding to at least one second time unit in the first time unit.

[0167] In some embodiments, at least one second time unit in the first time unit may include one or more third time units. In some embodiments, the first information may include time-domain information of the third time unit. This time-domain information may be used to indicate the time-domain location of one or more third time units in the first time unit.

[0168] In some embodiments, the time-domain information of the third time unit may include at least one of the following: the start position, length, and end position of the third time unit.

[0169] In some embodiments, the starting position of the third time unit can be the time-domain position of the first third time unit in a series of consecutive third time units. In one example, the starting position of the third time unit can indicate the position of the first third time unit in at least one second time unit within the first time unit. In other words, the starting position of the third time unit can indicate which second time unit the first third time unit is within at least one second time unit in the first time unit. For example, the starting position of the third time unit can be represented by the index number of the first third time unit in at least one second time unit within a series of consecutive third time units.

[0170] In some embodiments, the length of the third time unit can be the number of consecutive third time units. In some embodiments, the length can be used to represent the time-domain offset of the last third time unit relative to the first third time unit within a series of consecutive third time units. In some embodiments, consecutive third time units can occupy a certain amount of time-domain resources, i.e., have a certain duration. In this case, the length can be considered as a length. This length is used to represent the duration occupied by consecutive third time units in the time domain. In some embodiments, the length of the third time unit can be a positive integer. For example, the length of the third time unit can be greater than or equal to 1.

[0171] In some embodiments, the end position of the third time unit can be the time-domain position of the last third time unit in a series of consecutive third time units. In one example, the end position of the third time unit can indicate the position of the last third time unit in a series of consecutive third time units within at least one second time unit of the first time unit. In other words, the end position of the third time unit can indicate which second time unit the last third time unit is within at least one second time unit of the first time unit. For example, the end position of the third time unit can be represented by the index number of the last third time unit in a series of consecutive third time units within at least one second time unit.

[0172] In some embodiments, a continuous third time unit may include one or more second time units that are sequential in the time domain within the first time unit.

[0173] In some embodiments, the third time units may be distributed intermittently or continuously within the first time unit. In one example, all third time units within the first time unit may be continuously distributed. In this case, the time-domain information of the third time unit may include at least one of the following: a start position, a length, and an end position. In one example, all third time units within the first time unit may be discontinuously (i.e., intermittently) distributed. In this case, the time-domain information of the third time unit may include at least one of the following: multiple start positions, multiple lengths, and multiple end positions. For example, for each set of consecutive third time units, the time-domain information may include at least one of the start position, length, and end position.

[0174] In some embodiments, at least one second time unit in the first time unit may include one or more fourth time units. In some embodiments, the fourth time unit may be a second time unit within the first time unit corresponding to the length of the second CP. In some embodiments, the first information may include time-domain information of the fourth time unit. This time-domain information may be used to indicate the time-domain position of one or more fourth time units in the first time unit. In some embodiments, the time-domain information of the fourth time unit may include at least one of the following: the start position, length, and end position of the fourth time unit.

[0175] In some embodiments, at least one second time unit in the first time unit may include one or more fifth time units. In some embodiments, the fifth time unit may be a second time unit within the first time unit corresponding to the length of the third CP. In some embodiments, the first information may include time-domain information of the fifth time unit. This time-domain information may be used to indicate the time-domain position of one or more fifth time units in the first time unit. In some embodiments, the time-domain information of the fifth time unit may include at least one of the following: the start position, length, and end position of the fifth time unit.

[0176] In some embodiments, the lengths of the first CP, the second CP, and the third CP may be unequal to each other.

[0177] It should be noted that the time domain information of the fourth and fifth time units is similar to that of the third time unit, and will not be elaborated upon here.

[0178] In some embodiments, the first information may include a SLIV. In some embodiments, the SLIV may be used to indicate a start position and length. In some embodiments, the time-domain information may be a SLIV. In some embodiments, the time-domain information of the third time unit in the first information may include one or more SLIVs. In some embodiments, the time-domain information of the fourth time unit in the first information may include one or more SLIVs. In some embodiments, the time-domain information of the fifth time unit in the first information may include one or more SLIVs.

[0179] In some embodiments, the first information may include a bitmap. In some embodiments, the bitmap may also be referred to as a bitmap.

[0180] In some embodiments, the first information may include at least one bitmap. Each bitmap may correspond to a CP length. In one example, the number of bitmaps in the first information may be less than or equal to the number of at least one CP length corresponding to at least one second time unit within the first time unit. In one example, the first information may include at least one of the following: a bitmap corresponding to a third time unit, a bitmap corresponding to a fourth time unit, and a bitmap corresponding to a fifth time unit.

[0181] In some embodiments, the number of bits in the bitmap may be determined based on at least one of the following: the maximum number of second time units within the first time unit, and the number of second time units within the first time unit.

[0182] In some embodiments, the number of bits in the bitmap can be equal to the number of second time units within the first time unit. In some embodiments, the bits in the bitmap can correspond one-to-one with the second time units within the first time unit. In this case, each bit in the bitmap can be used to indicate whether the corresponding second time unit belongs to a specific category. In one example, for a third time unit, each bit in the bitmap can be used to indicate whether the corresponding second time unit is a third time unit, that is, whether the corresponding second time unit corresponds to the first CP length. For example, a bit in the bitmap can have a value of 1, which indicates that the corresponding second time unit is a third time unit; a bit in the bitmap can have a value of 0, which indicates that the corresponding second time unit is not a third time unit. For example, a bitmap value of 111000111000 can indicate that among the 12 second time units within the first time unit, the first to third and the seventh to ninth second time units can be third time units, that is, corresponding to the first CP length.

[0183] In some embodiments, the number of bits in the bitmap may be equal to the maximum number of second time units within the first time unit. In some embodiments, the bits in the bitmap may correspond one-to-one with the maximum possible number of second time units within the first time unit. In some embodiments, the number of bits in the bitmap may be greater than or equal to the number of second time units within the first time unit. In some embodiments, at least a portion of all the bits in the bitmap may be used to indicate the second time units within the first time unit. In one example, the first few bits or the last few bits in the bitmap may be used to indicate the second time units within the first time unit. In this case, the number of these bits may be equal to the number of second time units within the first time unit. In one example, for a third time unit, each bit in the bitmap may be used to indicate whether the corresponding second time unit is a third time unit, that is, whether the corresponding second time unit corresponds to the first CP length. For example, a bit in the bitmap may have a value of 1, which indicates that the corresponding second time unit is a third time unit; a bit in the bitmap may have a value of 0, which indicates that the corresponding second time unit is not a third time unit. For example, if the bitmap value is 11100011100000, then the first 12 bits in the bitmap can represent the 12 second time units within the first time unit, with the first to third and seventh to ninth second time units being the third time units, corresponding to the first CP length. Similarly, if the bitmap value is "00000011000011", then the last 12 bits in the bitmap can represent the 12 second time units within the first time unit, with the fifth, sixth, seventh, and eighth second time units being the third time units, corresponding to the first CP length.

[0184] In some embodiments, the number of bits in the bitmap may be greater than the number of second time units within the first time unit. In this case, the remaining bits may be invalid, except for the bits selected for indication. In some embodiments, the invalid bits may have values ​​of 0 or 1.

[0185] In some embodiments, the first information may be used to determine the CP length configuration corresponding to at least one time-domain granularity.

[0186] In some embodiments, the first information may include multiple parameters. These multiple parameters can be used to configure the CP length configuration corresponding to different temporal granularities.

[0187] In some embodiments, the first time unit may include at least one of the following: a time slot configuration period, a time slot configuration mode, a sub-time slot configuration mode, and a time slot.

[0188] In some embodiments, the second time unit may include at least one of the following: a time slot configuration mode, a sub-time slot configuration mode, a time slot, and a symbol.

[0189] In some embodiments, the time slot configuration period can be a time period associated with the first information cell. In some embodiments, the first information cell can correspond to a duration, which can serve as the time slot configuration period. In some embodiments, the first information cell can be used to configure a duration, which can serve as the time slot configuration period. In some embodiments, the first information cell can be used to implement parameter configuration within a duration, which can serve as the time slot configuration period. In one example, the first information cell can be TDD-UL-DL-ConfigCommon. For example, the duration of time slot configuration performed by TDD-UL-DL-ConfigCommon can be the time slot configuration period.

[0190] In some embodiments, the time slot configuration pattern can be a time period associated with the second information element. In some embodiments, the second information element can correspond to a duration, which can serve as the time slot configuration pattern. In some embodiments, the second information element can be used to configure a duration, which can serve as the time slot configuration pattern. In some embodiments, the second information element can be used to implement parameter configuration within a duration, which can serve as the time slot configuration pattern. In one example, the second information element can be TDD-UL-DL-Pattern. For example, the duration of time slot configuration performed by TDD-UL-DL-Pattern can be the time slot configuration pattern.

[0191] In some embodiments, the multiple parameters in the first information may include at least one of the following: a first parameter, a second parameter, and a third parameter. The first parameter, the second parameter, and the third parameter may correspond to different temporal granularities.

In some embodiments, at the first time-domain granularity, the first time unit may be a time-slot configuration period, and the second time unit may be a time-slot configuration mode. For example, the time-slot configuration period may include at least one time-slot configuration mode.

In some embodiments, at the second time-domain granularity, the first time unit may be a time-slot configuration pattern, and the second time unit may be a time slot. For example, the time-slot configuration pattern may include at least one time slot.

[0194] In some embodiments, the third parameter may correspond to a third time-domain granularity. In some embodiments, at the third time-domain granularity, the first time unit may be a time slot, and the second time unit may be a symbol. For example, a time slot may include at least one symbol.

[0195] In some embodiments, the first information may be used to determine a CP length configuration corresponding to one or more frequency ranges. In one embodiment, the first information may be used to determine multiple CP length configurations, which may correspond to different frequency ranges.

[0196] In some embodiments, one or more frequency ranges may be located within the frequency range of the carrier. In some embodiments, one or more frequency ranges may be located within the BWP.

[0197] In some embodiments, the first information may be used to determine the CP length configuration corresponding to the first frequency range and the second frequency range, respectively. In some embodiments, the first frequency range and the second frequency range may be located within a carrier frequency range or a BWP. In some embodiments, the first frequency range and the second frequency range may not overlap. The first frequency range and the second frequency range may be completely independent.

[0198] In some embodiments, the first information may include information for determining the CP length configuration corresponding to a first frequency range, and information for configuring the CP length corresponding to a second frequency range.

[0199] In some embodiments, the first information for determining the CP length configuration corresponding to the first frequency range and the first information for determining the CP length configuration corresponding to the second frequency range may be independent. In one example, the first information for determining the CP length configuration corresponding to the first frequency range and the first information for determining the CP length configuration corresponding to the second frequency range may be sent separately.

[0200] In some embodiments, the first information may be used to determine the CP length configuration corresponding to the third frequency range. In some embodiments, the number of CP length configurations within the third frequency range may be multiple. In some embodiments, the third frequency range may be located within a carrier frequency range or a BWP.

[0201] In some embodiments, the third frequency range may be less than the carrier frequency or BWP, and the carrier frequency or BWP may further include a fourth frequency range. In some embodiments, the fourth frequency range may not overlap with the third frequency range or may partially overlap. In some embodiments, within the fourth frequency range, the number of CP length configurations may be at least one.

[0202] In some embodiments, the CP length configuration in the third frequency range may be related to or unrelated to the CP length configuration in the fourth frequency range. In some embodiments, at least one CP length configuration in the fourth frequency range may be included in a plurality of CP length configurations in the third frequency range. In some embodiments, at least one CP length configuration in the fourth frequency range may be different from a plurality of CP length configurations in the third frequency range. In one example, at least one CP length configuration in the fourth frequency range is different from any of the plurality of CP length configurations in the third frequency range.

In some embodiments, within a fourth frequency range, at least one second time unit within a first time unit may correspond to one or more CP lengths. In some embodiments, the multiple CP lengths corresponding to at least one second time unit within the third frequency range and the one or more CP lengths corresponding to at least one second time unit within the fourth frequency range may be related or unrelated. In some embodiments, the multiple CP lengths corresponding to at least one second time unit within the third frequency range may be included in the one or more CP lengths corresponding to at least one second time unit within the fourth frequency range. In one example, the one or more CP lengths corresponding to at least one second time unit within the fourth frequency range may be included in the multiple CP lengths corresponding to at least one second time unit within the third frequency range. In one example, each CP length corresponding to at least one second time unit within the fourth frequency range may be one of the multiple CP lengths corresponding to at least one second time unit within the third frequency range. In some embodiments, the one or more CP lengths corresponding to at least one second time unit within the fourth frequency range may be independent of the multiple CP lengths corresponding to at least one second time unit within the third frequency range. In one example, one or more CP lengths corresponding to at least one second time unit in the fourth frequency range may be different from any of the multiple CP lengths corresponding to at least one second time unit in the third frequency range.

[0204] In some embodiments, the CP length configuration may correspond to different periods in different frequency ranges. In some embodiments, the period of the CP length configuration determined by the first information may be different in different frequency ranges. In one example, the period of the CP length configuration determined by the first information in a first frequency range and the period in a second frequency range may be different. In one example, the period of the CP length configuration determined by the first information in a third frequency range and the period in a fourth frequency range may be different.
