Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a frequency hopping indication method and device. Background Art

[0002] In the field of wireless communications, during the research of Rel-17 coverage enhancement, a solution was proposed to improve the uplink channel transmission performance through joint channel estimation. The prerequisites for joint channel estimation are power stability and phase continuity. The frequency hopping method supported by Rel-16 may destroy phase continuity when changing the frequency domain position. When there is only one uplink channel in each frequency hopping hop, joint channel estimation cannot be performed. Therefore, in order to obtain both frequency hopping gain and joint channel estimation gain at the same time, Rel-17 further proposed a new frequency hopping method.

[0003] The existing protocol does not have a mechanism to instruct the terminal device UE to perform the new frequency hopping method proposed by Rel-17. In addition, as the channel status conditions change, the UE may not be in a coverage-restricted scenario for a long time, and it is not necessary to always use the new frequency hopping method proposed by Rel-17. The current protocol also does not have a solution for dynamically switching between two different frequency hopping methods. Summary of the invention

[0121] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0122] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0123] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0124] The uplink channels include the Physical Uplink Shared Channel (PUSCH) and the Physical Uplink Control Channel (PUCCH). PUSCH is an uplink data channel scheduled for transmission by uplink DCI format 0_X (abbreviated as DCI 0_X). DCI 0_0 and DCI 0_1 are two types of uplink DCIs for scheduling PUSCH defined by the Rel-15 protocol, supporting the PUSCH repetition transmission mode of Rel-15. DCI 0_2 is an uplink DCI for scheduling PUSCH introduced by the Rel-16 protocol for Ultra Reliable Low Latency Communication (URLLC), supporting Type A and Type B PUSCH repetition transmission modes. PUSCHrepetition Type A is the slot-based PUSCH repetition transmission mode supported in the Rel-15 protocol; PUSCH repetition Type B is the mini-slot-based PUSCHrepetition transmission mode introduced by the Rel-16 protocol for URLLC. It should be noted that DCI 0_1 supports both Rel-15 and Rel-16 scheduling modes. PUCCH is a control channel that carries uplink control information (UCI). Hybrid Automatic Repeat request-ACKnowledge (HARQ-ACK) is a type of UCI, which is used for feedback information transmitted by the UE to the base station on whether the downlink data channel PDSCH scheduled by the downlink DCI 1_X is correctly received.

[0125] In the Rel-16 protocol, the uplink channel supports three frequency hopping modes: interRepetition, interSlot and intraSlot. Among them, PUSCH / PUCCH, which is transmitted only once, supports intraSlot frequency hopping; PUSCH repetition Type A supports interSlot and intraSlot frequency hopping, such as Figure 2 As shown; PUSCH repetition Type B supports interRepetition and interSlot frequency hopping, such as Figure 3As shown; PUCCH repetition supports interSlot and intraSlot frequency hopping, frequency hopping mode and Figure 2 The same as PUSCH repetition Type A.

[0126] During the research of Rel-17 coverage enhancement, a scheme was proposed to improve the uplink channel transmission performance through joint channel estimation. The prerequisites for joint channel estimation are power stability and phase continuity. The frequency hopping method supported by Rel-16 may destroy the phase continuity when changing the frequency domain position. When there is only one uplink channel in each hop, joint channel estimation cannot be performed. Therefore, in order to obtain the frequency hopping gain and the gain of the joint channel estimation at the same time, Rel-17 further proposed a new frequency hopping method, namely the first frequency hopping method in this application, which is another frequency hopping method different from the three frequency hopping methods of interRepetition, interSlot and intraSlot. Figure 1 FIG. 1 is a schematic diagram of a frequency hopping method in which two time slots are included in each hop when PUSCH is repeatedly transmitted four times. At this time, the base station can perform joint channel estimation on the first two PUSCHs and the last two PUSCHs respectively.

[0127] The activation of frequency hopping function of PUSCH requires the cooperation of high-level radio resource control (RRC) signaling and DCI signaling. First, RRC signaling selects intraSlot or interSlot when configuring frequencyHopping IE in PUSCH-config; or, when using DCI format 0_1 / 0_2 related to Rel-16 function to schedule PUSCH repetition, configure the corresponding IE in PUSCH-config to select the frequency hopping mode according to the PUSCHrepetition type. Then, when the Frequency hopping flag field value in the scheduling DCI corresponding to the uplink channel is 1, the UE uses the frequency hopping mode configured by RRC to transmit the uplink channel; when the Frequency hopping flag field value is 0, the UE turns off the frequency hopping function and transmits the uplink channel at the same frequency domain position.

[0128] To enable the frequency hopping function of PUCCH, only RRC signaling configuration is required. Among them, Intra-slot frequency hopping is configured separately for each PUCCHresource. When RRC signaling configures the intraSlotFrequencyHopping IE contained in the PUCCH-Resource in PUCCH-Config as enable, the PUCCH transmitted by this PUCCH resource adopts the intraSlot frequency hopping method; when RRC configures this IE by default, PUCCH is not transmitted in frequency hopping mode.

[0129] Inter-slot frequency hopping can only be enabled when PUCCH is repeatedly transmitted. The Rel-16 protocol stipulates that only long PUCCH, that is, PUCCH format 1 / 3 / 4 can be transmitted in repetition mode. Therefore, interSlot frequency hopping is configured for each PUCCH format and is bound to the PUCCH format. When the interSlotFrequencyHopping IE included in the PUCCH-FormatConfig in the PUCCH-Config is configured as enable in the RRC signaling, the PUCCH transmitted by the PUCCH resource corresponding to the PUCCHformat is selected to adopt the interSlot frequency hopping mode; when the RRC configures this IE by default, the PUCCH is not transmitted in frequency hopping mode.

[0130] The frequency hopping mechanism in Rel-16 can only configure three frequency hopping modes: interRepetition, interSlot and intraSlot, and cannot support the new frequency hopping mode proposed in Rel-17, namely the first frequency hopping mode, which is another frequency hopping mode different from the three frequency hopping modes of interRepetition, interSlot and intraSlot. At the same time, the existing technology adopts a semi-static configuration method to select the frequency hopping mode. When the frequency hopping mode needs to be switched, it can only be completed through RRC reconfiguration, and flexible dynamic switching cannot be achieved.

[0131] Therefore, a technical solution of the present application is proposed, and the core idea of ​​the present application is: high-level signaling configures the first frequency hopping mode directly or indirectly; when high-level signaling configures more than one frequency hopping mode, dynamic switching of the frequency hopping mode is achieved through DCI signaling.

[0132] Figure 4 This is one of the flow charts of a frequency hopping indication method provided in an embodiment of the present application, such as Figure 4 As shown, the embodiment of the present application provides a frequency hopping indication method, and the execution subject may be a terminal device, such as a mobile phone. The method includes:

[0133] Step 401: Receive a high-level signaling sent by a network device, where the high-level signaling is configured with a first frequency hopping mode or multiple candidate frequency hopping modes;

[0134] Specifically, the terminal device receives the high-level signaling sent by the network device. The configuration of the high-level signaling is mainly divided into two categories. One category is to configure a frequency hopping mode, and this frequency hopping mode is the first frequency hopping mode, and the first frequency hopping mode is another frequency hopping mode different from the three frequency hopping modes of interRepetition, interSlot and intraSlot. One category is to configure multiple frequency hopping modes, so as to realize the switching between different frequency hopping modes in the configured multiple frequency hopping modes. The configuration mode of multiple frequency hopping modes may have multiple forms, such as being configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration mode, such as {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, where frequency hopping mode A, frequency hopping mode B and frequency hopping mode C represent three different frequency hopping modes respectively.

[0135] Step 402: Based on the high-layer signaling, determine the frequency hopping mode of the uplink channel corresponding to the terminal device.

[0136] According to the frequency hopping mode configured in the high-level signaling, if a frequency hopping mode is configured, the terminal device determines whether to adopt the frequency hopping mode, and when a frequency hopping mode is configured, this frequency hopping mode is the first frequency hopping mode. If multiple frequency hopping modes are configured, the terminal device switches between the multiple frequency hopping modes by selecting a frequency hopping mode from the multiple frequency hopping modes.

[0137] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0138] Optionally, when the uplink channel is a physical uplink shared channel PUSCH, the method further includes:

[0139] Receiving first downlink control information DCI sent by the network device;

[0140] The determining, based on the high-layer signaling, a frequency hopping mode of an uplink channel corresponding to the terminal device includes:

[0141] In a case where the high-layer signaling is configured with a first frequency hopping mode, determining the first frequency hopping mode that is explicitly or implicitly configured based on the high-layer signaling;

[0142] Based on the first DCI, it is determined whether to adopt the first frequency hopping mode.

[0143] Specifically, when the uplink channel is a physical uplink shared control channel PUSCH, the terminal device receives high-layer signaling sent by the network side. The high-layer signaling can configure the first frequency hopping mode explicitly or implicitly. The terminal device learns the frequency hopping mode supported by the network side and can be allocated to the terminal. Then, the network side sends the first downlink control information DCI to the terminal device, and the terminal device determines whether to adopt the first frequency hopping mode according to the Frequency hopping flag in the DCI.

[0144] When the Frequency hopping flag in the DCI is 1, the terminal adopts the first frequency hopping mode; when the Frequency hopping flag in the DCI is 0, the terminal does not adopt the first frequency hopping mode;

[0145] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0146] Optionally, the determining the first frequency hopping mode of the explicit configuration includes:

[0147] Determine the first frequency hopping mode based on a first information element IE configured in a physical uplink shared control channel configuration PUSCH-config by the higher layer signaling; or

[0148] Determine the first frequency hopping mode based on a second information element IE configured in the PUSCH-config by the high-layer signaling;

[0149] The determining the implicitly configured first frequency hopping mode includes:

[0150] The first frequency hopping mode is determined based on the joint channel estimation (JCE) related configuration in the high-layer signaling.

[0151] Specifically, there are two main methods for explicitly configuring the first frequency hopping mode:

[0152] The first one is to configure the first frequency hopping mode in the first information element IE configured in PUSCH-config based on high-level signaling; wherein the first information element IE is an existing information element IE in PUSCH-config, and can configure the existing interRepetition, interSlot and intraSlot frequency hopping modes, and can also configure the first frequency hopping mode.

[0153] The first information element IE mainly includes frequencyHopping IE, frequencyHoppingDCI-0-1-r16IE and frequencyHoppingDCI-0-2-r16 IE, wherein the frequencyHoppingDCI-0-2-r16 IE includes pusch-RepTypeA IE and pusch-RepTypeB IE.

[0154] For example, when the Rel-15 scheduling mode is adopted, the frequencyHopping IE state of the PUSCH-config in the higher layer signaling is the first frequency hopping mode.

[0155] If the Rel-16 scheduling method is adopted, the frequencyHoppingDCI-0-1-r16 IE or frequencyHoppingDCI-0-2-r16IE state of PUSCH-config in the high-level signaling is the first frequency hopping mode; specifically, in frequencyHoppingDCI-0-2-r16, the configuration of the first frequency hopping mode is mainly achieved by setting the pusch-RepTypeA IE or pusch-RepTypeB IE state to the first frequency hopping mode.

[0156] The terminal device determines its own frequency hopping behavior, that is, the frequency hopping mode that it can adopt, according to the high-layer signaling configured with the first frequency hopping mode.

[0157] The second method is to configure the first frequency hopping mode in the second information element IE configured in PUSCH-config based on high-level signaling; wherein the second information element IE is an information element IE newly added to PUSCH-config, and is only used to configure the first frequency hopping mode.

[0158] The second information element IE in PUSCH-config is used to configure the first frequency hopping mode. By setting the state of the second information element IE to enable, it indicates that the frequency hopping mode that can be adopted by the uplink channel corresponding to the terminal device is the first frequency hopping mode.

[0159] In the present application, interBundling is used to represent the first frequency hopping mode in the present application, but the protection scope of the present application is not limited to the name interBundling, which is only used as an exemplary description.

[0160] The following is an example of configuring the first frequency hopping mode in the first information element IE by high-level signaling. The frequencyHopping IE and pusch-RepTypeA IE in PUSCH-config have three candidate values ​​{intraSlot, interSlot, interBundling}, and the pusch-RepTypeB IE has three candidate values ​​{interRepetition, interSlot, interBundling}. If the high-level signaling configures the frequencyHopping IE to interBundling, the base station sends the first downlink control information DCI 0_0, DCI 0_0 schedules PUSCH and the Frequencyhopping flag field value is 1, the UE uses the interBundling frequency hopping mode to transmit PUSCH. If the high-level signaling configures the pusch-RepTypeX IE to interBundling, the base station sends DCI 0_2 to schedule PUSCH and the Frequencyhopping flag field value is 1, the UE uses the interBundling frequency hopping mode to transmit PUSCH.

[0161] Compared with explicitly configuring the first frequency hopping mode, the first frequency hopping mode may also be implicitly configured, and the specific method is as follows:

[0162] The high-level signaling includes joint channel estimation JCE related configuration. When the high-level signaling is configured with the interSlot frequency hopping mode corresponding to the Rel-15 protocol or the interRepetition frequency hopping mode corresponding to the Rel-16 protocol, and the JCE related configuration of joint channel estimation is configured, it is determined that the frequency hopping mode that can be adopted by the uplink channel corresponding to the terminal device is the first frequency hopping mode.

[0163] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0164] Optionally, when the uplink channel is a physical uplink control channel PUCCH, determining the frequency hopping mode of the uplink channel corresponding to the terminal device based on the high-layer signaling includes:

[0165] In a case where the higher layer signaling configures a first frequency hopping mode, the first frequency hopping mode that is explicitly or implicitly configured is determined based on the higher layer signaling.

[0166] Specifically, when the uplink channel is a physical uplink control channel PUCCH, the terminal device receives a high-layer signaling sent by the network side, and the first frequency hopping mode is explicitly or implicitly configured in the high-layer signaling.

[0167] Among them, when the first frequency hopping mode is explicitly configured, the high-level signaling received by the terminal device configures the third information element IE in PUCCH-config, and the third information element IE is used to configure the first frequency hopping mode. That is, when the high-level signaling sets the state of the third information element IE in PUCCH-config to enable, it indicates that the frequency hopping mode that can be adopted by the uplink channel corresponding to the terminal device is the first frequency hopping mode.

[0168] For example, when the uplink channel is PUCCH, the interBundlingFrequencyHopping IE is newly configured in the PUCCH-config. If the high-level signaling configures the interBundlingFrequencyHoppingIE to the enable state, it can be stipulated that if the interSlotFrequencyHopping IE is also configured in the PUCCH-config, the UE ignores the configuration of the IE; or it can be stipulated that if the interBundlingFrequencyHopping IE is configured in the PUCCH-config, the configuration of the interSlotFrequencyHopping IE is not allowed.

[0169] In the case of implicitly configuring the first frequency hopping mode, when the high-level signaling configures both the interSlot frequency hopping mode and the joint channel estimation JCE related configuration, the terminal device determines that the frequency hopping mode that can be adopted by its corresponding uplink channel is the first frequency hopping mode.

[0170] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0171] The following explanation is given using the second information element IE configuration of the first frequency hopping mode in the high-level signaling PUSCH-config, and a new configuration of the interBundlingFrequencyHopping IE is added in the PUSCH-config. If the high-level signaling configures the interBundlingFrequencyHopping IE to the enable state, the base station sends the first DCI 0_0, DCI 0_0 schedules PUSCH and the Frequency hopping flag field value is 1, the UE uses the interBundling frequency hopping mode to transmit PUSCH. At this time, there may be IEs that configure two frequency hopping modes at the same time in the high-level signaling. It can be stipulated that if the frequencyHopping IE is also configured in the PUSCH-config, the UE ignores the frequency hopping modes configured in these IEs; similarly, it can also be stipulated that if the interBundlingFrequencyHopping IE is configured in the PUSCH-config, the configuration of the frequencyHopping IE is not allowed.

[0172] On the other hand, if the higher layer signaling configures the interBundlingFrequencyHopping IE to disable state or configures the interBundlingFrequencyHopping IE by default, when the base station sends DCI 0_0 to schedule PUSCH and the Frequency hopping flag field value is 1, the UE selects the final frequency hopping mode according to the configured frequencyHopping IE.

[0173] Take the implicit configuration of the first frequency hopping mode through the joint channel estimation JCE related configuration in the high-level signaling as an example. Take the PUSCH repetition scheduled by DCI 0_0 as an example. The high-level signaling configures the frequencyHopping IE in the PUSCH-config to the interSlot state, and the UE adopts interSlot hopping. The interbundling frequency hopping mode is an enhancement of interSlot hopping in the joint channel estimation scenario. At this time, when the high-level signaling is configured to enable the joint channel estimation function, the UE adopts the interBundling frequency hopping mode in the joint channel estimation JCE scenario by default. Similarly, if the high-level configures the time domain window size or the time domain frequency hopping interval, it is also considered that the base station will adopt the joint channel estimation mode at the receiving end, and the UE should adopt the interBundling frequency hopping mode at the transmitting end. However, when the time domain window size or the time domain frequency hopping interval is 1, although the high-level signaling configures the time domain window size or the time domain frequency hopping interval at this time, there is only one PUSCH in a time domain window or time domain frequency hopping interval, and joint channel estimation cannot be performed. At this time, the UE should use the interSlot frequency hopping method in this scenario.

[0174] Similarly, if it is PUSCH repetition Type B scheduled by DCI 0_2, high-level signaling is required to configure the pusch-RepTypeB IE as interRepetiton, and other behaviors are the same as the above embodiment and are not described in detail. When repetition Type B is used, if the pusch-RepTypeB IE is configured as interSlot, there are multiple PUSCH repetitions in one slot, and joint channel estimation can be performed directly without configuring the interBundling frequency hopping mode.

[0175] For PUCCH repetition, when the interslotFrequencyHopping IE in PUCCH-config is configured as enable, the UE uses the interSlot frequency hopping mode. Other configurations for implicitly enabling the interBundling frequency hopping mode are the same as those for the above PUSCH transmission, and will not be described in detail in this embodiment.

[0176] Optionally, the joint channel estimation JCE related configuration includes at least one of a time domain window size, a time domain frequency hopping interval, and turning on / off the joint channel estimation JCE.

[0177] Specifically, in the case of implicitly configuring the first frequency hopping mode, the existing frequency hopping mode is configured through high-level signaling as a prerequisite, and the configuration related to the joint channel estimation is configured at the same time to realize the configuration of the first frequency hopping mode. The configuration related to the joint channel estimation JCE can be realized by configuring at least one of the time domain window size, the time domain frequency hopping interval, and turning on / off the joint channel estimation JCE. For example, the time domain window size is configured to be 4, or the time domain frequency hopping interval is configured to be 2, or the joint channel estimation is turned on, etc. to complete the relevant configuration of the joint channel estimation JCE. The terminal device determines that the frequency hopping mode that can be adopted by its corresponding uplink channel is the first frequency hopping mode according to the above configuration. There is a special case. When the value of the time domain window size or the time domain frequency hopping interval in the joint channel estimation JCE related configuration is 1, it is determined that the uplink channel corresponding to the terminal device does not adopt the first frequency hopping mode. Among them, the time domain window size is the time domain length corresponding to one joint channel estimation when the UE performs joint channel estimation configured by high-level signaling; the time domain frequency hopping interval is the time domain length corresponding to one joint channel estimation, i.e. one hop, when the UE supports joint channel estimation while frequency hopping transmission configured by high-level signaling.

[0178] For example, when the time domain window size or the time domain frequency hopping interval is set to 1, although the time domain window size or the time domain frequency hopping interval is configured by the high-level signaling, there is only one PUCCH in a time domain window or the time domain frequency hopping interval, and joint channel estimation cannot be performed. At this time, the UE should use the interSlot frequency hopping mode in this scenario.

[0179] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0180] Optionally, the method further includes:

[0181] Receiving second downlink control information DCI sent by the network device;

[0182] The determining, based on the high-layer signaling, a frequency hopping mode of an uplink channel corresponding to the terminal device includes:

[0183] When the higher layer signaling configures a plurality of candidate frequency hopping modes, determining the configured plurality of candidate frequency hopping modes based on the higher layer signaling;

[0184] Based on the second DCI, the frequency hopping mode of the uplink channel corresponding to the terminal device is determined from the multiple candidate frequency hopping modes.

[0185] Specifically, in the case where multiple candidate frequency hopping modes are configured in the high-level signaling, the terminal device determines the candidate frequency hopping modes for the terminal device to perform frequency hopping based on the high-level signaling. The candidate frequency hopping modes include at least two frequency hopping modes, and the specific composition mode can be configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration mode, such as {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, where frequency hopping mode A, frequency hopping mode B and frequency hopping mode C represent three different frequency hopping modes respectively.

[0186] After receiving the second downlink control information DCI, the terminal device selects from the candidate frequency hopping modes according to the DCI to determine the frequency hopping mode of the uplink channel corresponding to the terminal device. In this way, the terminal device can switch between multiple frequency hopping modes.

[0187] The frequency hopping indication method provided in the embodiment of the present application configures multiple frequency hopping modes in high-level signaling, and the terminal device determines multiple candidate frequency hopping modes, and determines the frequency hopping mode of the uplink channel corresponding to the terminal device based on the second downlink control information, thereby realizing dynamic switching between multiple frequency hopping modes.

[0188] Optionally, when the high-layer signaling configures multiple candidate frequency hopping modes, the determining, based on the high-layer signaling, the configured multiple candidate frequency hopping modes includes:

[0189] In a case where the uplink channel is a physical uplink shared channel PUSCH, determining a plurality of explicitly or implicitly configured candidate frequency hopping modes based on the higher layer signaling;

[0190] In the case where the uplink channel is a physical uplink control channel PUCCH, a plurality of explicitly or implicitly configured candidate frequency hopping modes are determined based on the higher layer signaling.

[0191] Specifically, the uplink channels mainly include: physical uplink shared channel PUSCH and physical uplink control channel PUCCH, both of which can be explicitly or implicitly configured with multiple candidate frequency hopping modes by the network side through high-level signaling, and the terminal device determines the multiple explicitly or implicitly configured candidate frequency hopping modes according to the high-level information. Flexible configuration of multiple frequency hopping modes is achieved, and the terminal can select between multiple frequency hopping modes based on this and complete the switching of different frequency hopping modes.

[0192] The frequency hopping indication method provided in the embodiment of the present application configures multiple frequency hopping modes in high-level signaling, and the terminal device determines multiple candidate frequency hopping modes, and determines the frequency hopping mode of the uplink channel corresponding to the terminal device based on the second downlink control information, thereby realizing dynamic switching between multiple frequency hopping modes.

[0193] Optionally, when the uplink channel is a physical uplink shared channel PUSCH, determining multiple explicitly or implicitly configured candidate frequency hopping modes based on the high-layer signaling includes:

[0194] The determining of multiple explicitly configured candidate frequency hopping modes includes:

[0195] Determine multiple candidate frequency hopping modes based on the first information element IE configured in the PUSCH-config by the high-layer signaling; or

[0196] Determine, based on a second information element IE configured by the high-level signaling in the PUSCH-config, a plurality of candidate frequency hopping modes, wherein a first frequency hopping mode among the plurality of candidate frequency hopping modes is determined by the second information element IE configured by the high-level signaling in the PUSCH-config, and other frequency hopping modes among the plurality of candidate frequency hopping modes except the first frequency hopping mode are determined by the first information element IE configured by the high-level signaling in the PUSCH-config;

[0197] The determining of multiple implicitly configured candidate frequency hopping modes includes:

[0198] Based on the joint channel estimation (JCE) related configuration in the high-layer signaling, a plurality of candidate frequency hopping modes including the first frequency hopping mode are determined.

[0199] Specifically, when the uplink channel is a physical uplink shared channel PUSCH, the terminal device determines multiple candidate frequency hopping modes that can be used for its uplink channel based on high-level signaling that explicitly or implicitly configures multiple candidate frequency hopping modes.

[0200] The multiple candidate frequency hopping modes for explicit configuration are determined, specifically including:

[0201] Based on the first information element IE configured in PUSCH-config by high-level signaling, multiple candidate frequency hopping modes are determined; wherein the first information element IE is an existing information element IE in PUSCH-config, and can configure the existing interRepetition, interSlot and intraSlot frequency hopping modes, or the first frequency hopping mode. The multiple candidate frequency hopping modes include two or more frequency hopping modes, and the specific form is, for example, the first information element IE is configured with a frequency hopping mode configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration mode, such as {frequency hopping mode B and frequency hopping mode C} or {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, wherein frequency hopping mode A, frequency hopping mode B and frequency hopping mode C represent three different frequency hopping modes respectively, and any one of them can represent the first frequency hopping mode.

[0202] Based on the second information element IE configured by the high-level signaling in the PUSCH-config, multiple candidate frequency hopping modes are determined; wherein a first frequency hopping mode among the multiple candidate frequency hopping modes is determined by the second information element IE configured by the high-level signaling in the PUSCH-config, and other frequency hopping modes among the multiple candidate frequency hopping modes except the first frequency hopping mode are determined by the first information element IE configured by the high-level signaling in the PUSCH-config.

[0203] Specifically, the determined multiple candidate frequency hopping modes are configured by the first information element IE and the second information element IE in the PUSCH-config, and the second information element IE is a newly added information element IE in the PUSCH-config, which is mainly used to configure the first frequency hopping mode. For example, the multiple candidate frequency hopping modes are {first frequency hopping mode, frequency hopping mode B and frequency hopping mode C}, where "the first frequency hopping mode" is determined by the second information element IE, and "frequency hopping mode B and frequency hopping mode C" are determined by the first information element IE.

[0204] The multiple candidate frequency hopping modes for implicit configuration are determined, specifically including:

[0205] When high-level signaling configures one or more candidate frequency hopping modes in the first information element IE configured in PUSCH-config, and the configuration related to joint channel estimation JCE is configured, multiple candidate frequency hopping modes that can be adopted by the uplink channel corresponding to the terminal device are determined, including the first frequency hopping mode.

[0206] The frequency hopping indication method provided in the embodiment of the present application, when the uplink channel is PUSCH, configures multiple frequency hopping modes explicitly or implicitly in high-level signaling, and when explicitly configured, uses the first information element IE or the second information element IE in PUSCH-config to complete the relevant configuration; when implicitly configured, combines the configuration related to the joint channel estimation JCE to complete the relevant configuration of multiple frequency hopping modes. This makes the method for the terminal device to determine multiple candidate frequency hopping modes more flexible, thereby realizing dynamic switching between multiple frequency hopping modes.

[0207] Optionally, the determining, based on the first information element IE configured in the PUSCH-config by the high-level signaling, multiple candidate frequency hopping modes includes:

[0208] The determined multiple candidate frequency hopping modes include a first frequency hopping mode.

[0209] Specifically, when the high-level signaling determines multiple candidate frequency hopping modes only according to the first information element IE configured in the PUSCH-config, the multiple candidate frequency hopping modes determined by the terminal device include the first frequency hopping mode.

[0210] Optionally, when the uplink channel is a physical uplink control channel PUCCH, determining multiple explicitly or implicitly configured candidate frequency hopping modes based on the high-layer signaling includes:

[0211] The determining of multiple explicitly configured candidate frequency hopping modes includes:

[0212] Determine, based on the third information element IE configured by the high-level signaling in the PUCCH-config, multiple candidate frequency hopping modes, wherein a first frequency hopping mode among the multiple candidate frequency hopping modes is determined by the third information element IE configured in the high-level signaling PUCCH-config, and other frequency hopping modes among the multiple candidate frequency hopping modes except the first frequency hopping mode are determined by the fourth information element IE configured by the high-level signaling in the PUCCH-config;

[0213] The determining of multiple implicitly configured candidate frequency hopping modes includes:

[0214] Based on the joint channel estimation (JCE) related configuration in the high-layer signaling, a plurality of candidate frequency hopping modes including the first frequency hopping mode are determined.

[0215] Specifically, when the uplink channel is a physical uplink control channel PUCCH, the terminal device determines multiple candidate frequency hopping modes that can be adopted by its uplink channel based on high-layer signaling that is explicitly or implicitly configured with multiple candidate frequency hopping modes.

[0216] Among them, multiple explicitly configured candidate frequency hopping modes are determined, and multiple candidate frequency hopping modes including the first frequency hopping mode are determined by the third information element IE configured in the PUCCH-config by the high-level signaling. And the first frequency hopping mode is determined by the third information element IE configured in the high-level signaling PUCCH-config. And the existing frequency hopping mode is determined by the fourth information element IE configured in the high-level signaling PUCCH-config.

[0217] When determining multiple implicitly configured candidate frequency hopping modes, if the fourth information element IE configured in the PUCCH-config through high-level signaling is configured with one or more candidate frequency hopping modes, and the configuration related to joint channel estimation is configured, then multiple candidate frequency hopping modes that can be adopted by the uplink channel corresponding to the terminal device are determined, including the first frequency hopping mode.

[0218] The frequency hopping indication method provided in the embodiment of the present application, when the uplink channel is PUCCH, configures multiple frequency hopping modes explicitly or implicitly in high-level signaling. When explicitly configured, the third information element IE configured in PUCCH-config is used to complete the relevant configuration; when implicitly configured, the relevant configuration of multiple frequency hopping modes is completed in combination with the configuration related to the joint channel estimation JCE. This makes the method for the terminal device to determine multiple candidate frequency hopping modes more flexible, thereby realizing dynamic switching between multiple frequency hopping modes.

[0219] Optionally, the joint channel estimation JCE related configuration includes at least one of a time domain window size, a time domain frequency hopping interval, and turning on / off the joint channel estimation JCE.

[0220] Specifically, in the case of implicitly configuring the first frequency hopping mode, the configuration of the existing frequency hopping mode is performed through high-level signaling as a prerequisite, and the configuration related to the joint channel estimation JCE is configured to implement the configuration of the first frequency hopping mode. The configuration related to the joint channel estimation JCE can be implemented by at least one of the time domain window size, the time domain frequency hopping interval, and turning on / off the joint channel estimation JCE. For example, the time domain window size is configured to be 4, or the time domain frequency hopping interval is configured to be 2, or the joint channel estimation JCE is turned on, etc. to complete the relevant configuration of the joint channel estimation JCE, and the terminal device determines that the frequency hopping mode that can be adopted by its corresponding uplink channel is the first frequency hopping mode. There is a special case. When the value of the time domain window size or the time domain frequency hopping interval in the joint channel estimation JCE related configuration is 1, it is determined that the uplink channel corresponding to the terminal device does not adopt the first frequency hopping mode.

[0221] For example, when the time domain window size or the time domain frequency hopping interval is set to 1, although the time domain window size or the time domain frequency hopping interval is configured by the high-level signaling, there is only one PUCCH in a time domain window or the time domain frequency hopping interval, and joint channel estimation cannot be performed. In this case, the UE should use the interSlot frequency hopping mode.

[0222] The frequency hopping indication method provided in the embodiment of the present application adopts a method for configuring the joint channel estimation JCE related configuration when multiple frequency hopping modes are implicitly configured in high-level signaling, and can complete the relevant configuration of the joint channel estimation JCE through any one of the time domain window size, the time domain frequency hopping interval, and turning on / off the joint channel estimation JCE, or a combination thereof, thereby improving the flexibility of the configuration.

[0223] Optionally, the second DCI includes at least one of an uplink DCI for scheduling PUSCH and a downlink DCI for scheduling PDSCH corresponding to the HARQ-ACK transmitted on the PUCCH.

[0224] Specifically, the received second downlink control information DCI may be an uplink DCI for scheduling PUSCH, or a downlink DCI for scheduling PDSCH corresponding to HARQ-ACK transmitted on PUCCH, both of which can realize the selection of the final frequency hopping mode from multiple candidate frequency hopping modes.

[0225] Optionally, determining, based on the second DCI, a frequency hopping mode of an uplink channel corresponding to the terminal device includes:

[0226] Determine the frequency hopping mode of the uplink channel corresponding to the terminal device based on the frequency hopping mode indicated by the first indication field in the second DCI; wherein the state value of the first indication field corresponds one-to-one to the frequency hopping mode; or

[0227] Determine the frequency hopping mode of the uplink channel corresponding to the terminal device based on the extended Frequency hopping flag field in the second DCI; wherein the state value of the extended Frequency hopping flag field corresponds one-to-one to the frequency hopping mode; or

[0228] Based on the Frequency hopping flag field in the second DCI, determine the first frequency hopping mode of the uplink channel corresponding to the terminal device; wherein the state value of the Frequency hopping flag field corresponds one-to-one to the frequency hopping mode.

[0229] Specifically, multiple candidate frequency hopping modes may exist in multiple forms, such as a frequency hopping mode configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration, such as {frequency hopping mode B and frequency hopping mode C} or {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, wherein frequency hopping mode A, frequency hopping mode B and frequency hopping mode C respectively represent three different frequency hopping modes, any one of which can represent the first frequency hopping mode.

[0230] The terminal device selects a frequency hopping mode adopted by its corresponding uplink channel from multiple candidate frequency hopping modes according to the second DCI, as follows:

[0231] According to the first indication field in the second DCI, the first indication field is different from the existing indication bit in the second DCI, and each state value field in the first indication field has a one-to-one correspondence with the frequency hopping mode, and different state values ​​are selected, that is, the frequency hopping mode adopted by the corresponding uplink channel is determined; for example, when the first indication field is a first candidate value, the terminal adopts a first frequency hopping mode; when the first indication field is a second candidate value, the terminal adopts a second frequency hopping mode; and so on;

[0232] Or, according to the frequency hopping flag field expanded in the second DCI, the state value of the frequency hopping flag field expanded corresponds to the frequency hopping mode. For example, if it is expanded to 2 bits, there are 4 corresponding state values, each frequency hopping mode corresponds to a state value, and the hopping off state corresponds to a state value;

[0233] Or, according to the Frequency hopping flag field in the second DCI, and the state value of the Frequency hopping flag field corresponds one-to-one with the frequency hopping mode. Re-interpret the state value of the Frequency hopping flag field in the second DCI, when the state value is 0, the terminal device adopts the first frequency hopping mode; when the state value is 1, the terminal device adopts the second frequency hopping mode.

[0234] The frequency hopping indication method provided in the embodiment of the present application, when multiple frequency hopping modes are configured in the high-level signaling, determines the frequency hopping mode of the uplink channel corresponding to the terminal device through the state value in the second DCI. The state value of the second DCI can be determined by using the first indication field in the second DCI, the expanded Frequency hopping flag field, or the re-interpretation of the Frequency hopping flag field. Different state values ​​in each field correspond to different frequency hopping modes, so that the frequency hopping mode can be selected by selecting different state values.

[0235] Take the example of two candidate frequency hopping modes configured by high-level signaling. The configuration mode can be based on the first IE configuration, the second / third IE configuration, or any of the three modes implicitly determined according to the joint channel estimation configuration. For example, based on the fact that the first IE configuration is only applicable to PUSCH, the candidate value of the frequencyHopping IE in PUSCH-config is expanded to {intraSlot, interSlot, interBundling, interSlot and interBundling}. When the high-level signaling configures the interSlot and interBundling state for the frequencyHopping IE, the UE has two candidate frequency hopping modes. In addition, the two candidate frequency hopping modes can also be expanded to a combination of any two frequency hopping modes.

[0236] Based on the second / third IE configuration being applicable to PUSCH / PUCCH, the high-level signaling configures the interBundlingFrequencyHopping IE to an enable state, and another candidate frequency hopping mode is the interSlot frequency hopping mode. In addition, another frequency hopping mode may also be other frequency hopping modes.

[0237] The implicit determination based on the joint channel estimation JCE configuration is applicable to PUSCH / PUCCH. Since the premise of implicit determination is that the first IE in the high-level signaling configures the interSlot or interRepetition frequency hopping mode, in addition to the interBundling frequency hopping mode, another candidate frequency hopping mode is interSlot or interRepetition.

[0238] Assume that high-level signaling configures interSlot frequency hopping mode and interBundling frequency hopping mode for PUSCH repetition Type A. The first indication field in the second DCI for scheduling PUSCH indicates the frequency hopping mode. For example, a 1-bit field is added in DCI 0_2 to indicate the frequency hopping pattern. When Frequency hopping flag = 1 and the bit field value is 0, the UE adopts the interSlot frequency hopping mode; when the bit field value is 1, the UE adopts the interBundling frequency hopping mode, and vice versa. When Frequency hopping flag = 0, the UE does not use the frequency hopping mode to transmit PUSCH.

[0239] Similarly, a 1-bit indication field can correspond to any two frequency hopping modes; or, a 2-bit indication field can be added to the DCI 0_2 for scheduling PUSCH to indicate the frequency hopping mode, corresponding to intraSlot frequency hopping, interSlot frequency hopping and interBundling frequency hopping. Similarly, for other PUSCH repetitions and PUCCH repetitions, N bits can be added to the scheduling DCI for dynamic switching of frequency hopping modes.

[0240] In response to the expanded Frequency hopping flag field in the second DCI, the high-level signaling PUSCHrepetition Type A configures interSlot hopping and interBundling frequency hopping methods. The second DCI for scheduling PUSCH, such as the Frequency hopping flag field in DCI 0_2, is expanded to 2 bits. When Frequency hopping flag = 00, the UE does not use frequency hopping to transmit PUSCH; when Frequency hopping flag = 01, the UE uses interSlot frequency hopping; when Frequency hopping flag = 10, the UE uses interBundling frequency hopping; the remaining Frequency hopping flag = 11 is used as the reserved value (or instructs the UE to use the intraSlot method). The 4 candidate values ​​correspond to the above four states, and other corresponding methods are also possible. Similarly, for other PUSCHrepetitions and PUCCH repetitions, the Frequency hopping flag field in the scheduling DCI can be expanded to 2 bits to indicate different hopping behaviors.

[0241] In response to the reinterpretation of the Frequency hopping flag field in the second DCI, the high-level signaling PUSCHrepetition Type A configures interSlot hopping and interBundling frequency hopping methods. Different hopping behaviors are indicated by reinterpreting the Frequency hopping flag field in the DCI 0_2 that schedules PUSCH. When Frequency hopping flag = 0, the UE adopts the interSlot frequency hopping method; when Frequency hopping flag = 1, the UE adopts the interBundling frequency hopping method. In this embodiment, the UE cannot turn off the frequency hopping function. Similarly, for other PUSCH repetitions and PUCCH repetitions, the Frequency hopping flag field can be reinterpreted to indicate different frequency hopping behaviors.

[0242] Figure 5 FIG. 2 is a flow chart of the frequency hopping indication method provided in the embodiment of the present application; Figure 5 As shown, the embodiment of the present application provides a frequency hopping indication method, which is applied to a network side device, including:

[0243] Step 501: Send a high-layer signaling to a terminal device; the high-layer signaling is configured with a first frequency hopping mode or configured with multiple candidate frequency hopping modes.

[0244] Specifically, the network side device configures a frequency hopping mode or configures multiple candidate frequency hopping modes through high-level signaling, and sends the high-level signaling to the terminal device, so that the terminal device can determine the frequency hopping mode used by its corresponding uplink channel based on the high-level signaling. When configuring a frequency hopping mode, the frequency hopping mode is the first frequency hopping mode. When configuring multiple frequency hopping modes, the first frequency hopping mode may be included.

[0245] The frequency hopping indication method provided in the embodiment of the present application configures a newly added first frequency hopping mode in the high-level signaling on the network side, thereby determining the first frequency hopping mode of the uplink channel according to the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, the uplink channel corresponding to the terminal device can be dynamically switched between multiple frequency hopping modes.

[0246] Optionally, when the uplink channel is a physical uplink shared channel PUSCH, the sending of high-layer signaling to the terminal device includes:

[0247] Sending high-layer signaling to the terminal device to explicitly or implicitly configure the first frequency hopping mode;

[0248] After sending the high-level signaling to the terminal device, the method further includes:

[0249] Sending first downlink control information DCI to the terminal device;

[0250] Based on the first DCI, the terminal device is instructed to adopt or not adopt the first frequency hopping mode.

[0251] Specifically, in the case where the uplink channel is a physical uplink shared channel PUSCH, the corresponding high-level signaling can configure the first frequency hopping mode explicitly or implicitly, and send the first downlink control information DCI to the terminal device, so that the terminal device can determine that its corresponding uplink channel adopts the first frequency hopping mode according to the high-level signaling, and determine whether to adopt or not adopt the first frequency hopping mode according to the first DCI. For example, when the Frequency hopping flag=1 in the first DCI, the terminal device adopts the frequency hopping mode, that is, the first frequency hopping mode; when the Frequency hopping flag=0 in the first DCI, the terminal device does not perform frequency hopping, that is, does not adopt the first frequency hopping mode.

[0252] The frequency hopping indication method provided in the embodiment of the present application configures a newly added first frequency hopping mode in the high-level signaling on the network side, thereby determining the first frequency hopping mode of the uplink channel according to the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, the uplink channel corresponding to the terminal device can be dynamically switched between multiple frequency hopping modes.

[0253] Optionally, the explicitly configuring the first frequency hopping mode includes:

[0254] Configure the first frequency hopping mode based on a first information element IE configured in PUSCH-config by the higher layer signaling; or

[0255] Configure the first frequency hopping mode based on the second information element IE configured in the PUSCH-config by the high-layer signaling;

[0256] The implicitly configuring the first frequency hopping mode includes:

[0257] The first frequency hopping mode is configured based on the joint channel estimation (JCE) related configuration in the high-layer signaling.

[0258] Specifically, the network side may configure the first frequency hopping mode explicitly or implicitly, and the corresponding implementation methods include:

[0259] When the first frequency hopping mode is explicitly configured, there are mainly two ways:

[0260] Method 1: Configure the first frequency hopping mode by configuring the first information element IE in PUSCH-config through high-level signaling; wherein the first information element IE is an existing information element IE in PUSCH-config, and can configure the existing interRepetition, interSlot and intraSlot frequency hopping modes, or the first frequency hopping mode.

[0261] For example, if PUSCH repetition Type A is used, the frequencyHopping IE or pusch-RepTypeA IE state of PUSCH-config in the higher layer signaling is the first frequency hopping mode;

[0262] If PUSCH repetition Type B is used, the pusch-RepTypeB IE state of PUSCH-config in the higher layer signaling is the first frequency hopping mode;

[0263] Method 2: configuring the first frequency hopping mode through a second information element IE configured in PUSCH-config through high-layer signaling; wherein the second information element IE is an information element IE newly added in PUSCH-config.

[0264] For example, the state of the second information element IE configured by the high-level signaling in the PUSCH-config is set to enable, and the high-level signaling configures the first frequency hopping mode.

[0265] When the first frequency hopping mode is implicitly configured, it is mainly implemented through the joint channel estimation JCE related configuration in the high-level signaling, that is, when the high-level signaling configures the interSlot frequency hopping mode or the interRepetition frequency hopping mode and configures the joint channel estimation JCE related configuration, the PUSCH corresponding to the terminal device adopts the first frequency hopping mode;

[0266] Correspondingly, if the uplink channel is a physical uplink control channel PUCCH, the network device may also explicitly or implicitly configure the first frequency hopping mode and send it to the terminal device.

[0267] The first frequency hopping mode is explicitly configured, mainly by configuring the third information element IE in PUCCH-config through high-level signaling, to configure the first frequency hopping mode; wherein the third information element IE is a newly added information element IE in PUCCH-config. For example, if the state of the third information element IE configured in the high-level signaling PUCCH-config is set to enable, the high-level signaling configures the first frequency hopping mode.

[0268] The implicit configuration of the first frequency hopping mode is mainly achieved through the joint channel estimation JCE related configuration in the high-level signaling, that is, when the high-level signaling configures the interSlot frequency hopping mode and the joint channel estimation JCE related configuration, the terminal adopts the first frequency hopping mode.

[0269] The frequency hopping indication method provided in the embodiment of the present application configures a newly added first frequency hopping mode in the high-level signaling by the network side, so as to determine the first frequency hopping mode of the uplink channel according to the high-level signaling; and explicitly configures the first frequency hopping mode through the first information element IE or the second / third information element IE in the high-level signaling, and implicitly configures the first frequency hopping mode through the configuration related to the joint channel estimation JCE.

[0270] Optionally, the joint channel estimation JCE related configuration includes at least one of a time domain window size, a time domain frequency hopping interval, and turning on / off the joint channel estimation JCE.

[0271] Specifically, when the network side implicitly configures the first frequency hopping mode, it needs to be implemented using the joint channel estimation JCE and related configurations. The configuration related to the joint channel estimation JCE can be implemented through at least one of the time domain window size, the time domain frequency hopping interval, and turning on / off the joint channel estimation JCE. For example, the time domain window size is configured to be 4, or the time domain frequency hopping interval is configured to be 2, or the joint channel estimation JCE is turned on, etc. to complete the relevant configuration of the joint channel estimation JCE. The terminal device determines that the frequency hopping mode that can be used for its corresponding uplink channel is the first frequency hopping mode. There is a special case. When the value of the time domain window size or the time domain frequency hopping interval in the joint channel estimation JCE related configuration is 1, it is determined that the uplink channel corresponding to the terminal device does not use the first frequency hopping mode.

[0272] For example, when the time domain window size or the time domain frequency hopping interval is 1, although the high-level signaling configures the time domain window size or the time domain frequency hopping interval, the frequency hopping mode is consistent with the interSlot frequency hopping mode, and the terminal device UE should adopt the interSlot frequency hopping mode.

[0273] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0274] Optionally, the sending of high-layer signaling to the terminal device includes:

[0275] Sending a high-level signaling to a terminal device, wherein the high-level signaling is configured with a plurality of candidate frequency hopping modes;

[0276] After sending the high-level signaling to the terminal device, the method further includes:

[0277] Sending second downlink control information DCI to the terminal device;

[0278] Based on the second DCI, the terminal device is instructed to determine the frequency hopping mode of the corresponding uplink channel from the multiple candidate frequency hopping modes.

[0279] Specifically, when the network side configures multiple candidate frequency hopping modes, after the terminal device determines multiple candidate frequency hopping modes according to the high-level signaling, the network device sends the second downlink control information DCI to the terminal device, and the terminal device selects from the candidate frequency hopping modes according to the DCI to determine the frequency hopping mode of the uplink channel corresponding to the terminal device. In this way, the terminal device can switch between multiple frequency hopping modes.

[0280] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0281] Optionally, the sending of high-layer signaling to the terminal device, wherein the high-layer signaling is configured with multiple candidate frequency hopping modes, including:

[0282] In a case where the uplink channel is a physical uplink shared channel PUSCH, explicitly or implicitly configuring a plurality of candidate frequency hopping modes based on the high-layer signaling;

[0283] In the case where the uplink channel is a physical uplink control channel PUCCH, a plurality of candidate frequency hopping modes are explicitly or implicitly configured based on the higher layer signaling.

[0284] Specifically, the uplink channels mainly include a physical uplink shared channel PUSCH and a physical uplink control channel PUCCH, both of which can be explicitly or implicitly configured with multiple candidate frequency hopping modes through high-layer signaling.

[0285] When the uplink channel is a physical uplink shared channel PUSCH, there are two ways to explicitly configure multiple candidate frequency hopping modes:

[0286] Mode 1: The first information element IE configured by the high-level signaling in the PUSCH-config configures multiple candidate frequency hopping modes; wherein the first information element IE is an existing information element IE in the PUSCH-config.

[0287] The multiple candidate frequency hopping modes include two or more frequency hopping modes, and the specific form is, for example, that the first information element IE is configured with a frequency hopping mode configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration mode, such as {frequency hopping mode B and frequency hopping mode C} or {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, wherein frequency hopping mode A, frequency hopping mode B and frequency hopping mode C represent three different frequency hopping modes, and any one of them can represent the first frequency hopping mode. That is, the multiple candidate frequency hopping modes configured by the first information element IE in the high-level signaling PUSCH-config may include the first frequency hopping mode, or may not include the first frequency hopping mode.

[0288] Method 2: configuring the first frequency hopping mode through a second information element IE configured in PUSCH-config through high-layer signaling; wherein the second information element IE is an information element IE newly added in PUSCH-config.

[0289] The first frequency hopping mode among the multiple candidate frequency hopping modes is determined by the second information element IE configured by PUSCH-config in the high-level signaling, and the other frequency hopping modes among the multiple candidate frequency hopping modes except the first frequency hopping mode are determined by the first information element IE configured by the high-level signaling in PUSCH-config.

[0290] That is, the determined multiple candidate frequency hopping modes are jointly configured by the first information element IE and the second information element IE configured by the high-level signaling in PUSCH-config. For example, the multiple candidate frequency hopping modes are {first frequency hopping mode, frequency hopping mode B and frequency hopping mode C}, wherein the "first frequency hopping mode" is determined by the second information element IE configured by the high-level signaling in PUSCH-config, and the "frequency hopping mode B and frequency hopping mode C" are determined by the first information element IE in the high-level signaling PUSCH-config.

[0291] The implementation method of implicitly configuring multiple candidate frequency hopping modes specifically includes:

[0292] When the first information element IE configured in the high-level signaling in PUSCH-config configures one or more candidate frequency hopping modes and the joint channel estimation JCE related configuration is configured, multiple candidate frequency hopping modes that can be used for the uplink channel corresponding to the terminal device are determined, including the first frequency hopping mode.

[0293] Correspondingly, if the uplink channel is a physical uplink control channel PUCCH, the network device may also configure multiple frequency hopping modes explicitly or implicitly and send them to the terminal device.

[0294] Among them, multiple frequency hopping modes are explicitly configured, mainly through high-level signaling in the third information element IE of PUCCH-config, to configure the first frequency hopping mode; for example, the third information element IE state configured by the high-level signaling in PUCCH-config is set to enable, and the high-level signaling configures the first frequency hopping mode; the other frequency hopping modes among the multiple candidate frequency hopping modes except the first frequency hopping mode are determined by the fourth information element IE configured by the high-level signaling in PUCCH-config.

[0295] The implicit configuration of the first frequency hopping mode is mainly achieved through the joint channel estimation JCE related configuration in the high-level signaling, that is, when the high-level signaling configures the interSlot frequency hopping mode and the joint channel estimation JCE related configuration, the terminal adopts the first frequency hopping mode.

[0296] The frequency hopping indication method provided in the embodiment of the present application configures a newly added first frequency hopping mode in the high-level signaling by the network side, so as to determine the first frequency hopping mode of the uplink channel according to the high-level signaling; and explicitly configures the first frequency hopping mode through the first information element IE or the second / third information element IE in the high-level signaling, and implicitly configures the first frequency hopping mode through the configuration related to the joint channel estimation JCE.

[0297] Optionally, the joint channel estimation JCE related configuration includes at least one of a time domain window size, a time domain frequency hopping interval, and turning on / off the joint channel estimation JCE.

[0298] Specifically, when the network side implicitly configures the first frequency hopping mode, it needs to be implemented using joint channel estimation (JCE) related configurations, and configuring the joint channel estimation (JCE) related configurations can be implemented through at least one of the time domain window size, the time domain frequency hopping interval, and turning on / off the joint channel estimation. For example, the time domain window size is configured to be 4, or the time domain frequency hopping interval is configured to be 2, or the joint channel estimation (JCE) is turned on to complete the relevant configuration of the joint channel estimation (JCE), and the terminal device determines that the frequency hopping mode that can be used for its corresponding uplink channel is the first frequency hopping mode. There is a special case. When the value of the time domain window size or the time domain frequency hopping interval in the joint channel estimation (JCE) related configuration is 1, it is determined that the uplink channel corresponding to the terminal device does not use the first frequency hopping mode.

[0299] For example, when the time domain window size or the time domain frequency hopping interval is 1, although the high-level signaling configures the time domain window size or the time domain frequency hopping interval, the corresponding frequency hopping mode is consistent with the interSlot frequency hopping mode, and the terminal device UE should adopt the interSlot frequency hopping mode.

[0300] The frequency hopping indication method provided in the embodiment of the present application realizes determining the first frequency hopping mode of the uplink channel according to the high-level signaling by configuring a newly added first frequency hopping mode in the high-level signaling; when multiple frequency hopping modes are configured in the high-level signaling, dynamic switching between multiple frequency hopping modes is realized.

[0301] Optionally, the second DCI includes at least one of an uplink DCI for scheduling PUSCH and a downlink DCI for scheduling PDSCH corresponding to the HARQ-ACK transmitted on the PUCCH.

[0302] Specifically, the second downlink control information DCI sent by the network side may be an uplink DCI for scheduling PUSCH, or a downlink DCI for scheduling PDSCH corresponding to the HARQ-ACK transmitted on the PUCCH, both of which may realize the selection of the final frequency hopping mode from multiple candidate frequency hopping modes.

[0303] Optionally, the instructing the terminal device to determine a frequency hopping mode of a corresponding uplink channel based on the second DCI includes:

[0304] Instructing the terminal device to determine the frequency hopping mode of the corresponding uplink channel based on the first indication field in the second DCI indicating the frequency hopping mode; wherein the state value of the first indication field corresponds one-to-one to the frequency hopping mode; or

[0305] Based on the extended Frequency hopping flag field in the second DCI, instruct the terminal device to determine the frequency hopping mode of the corresponding uplink channel; wherein the state value of the extended Frequency hopping flag field corresponds one-to-one to the frequency hopping mode; or

[0306] Based on the Frequency hopping flag field in the second DCI, the terminal device is instructed to determine the frequency hopping mode of the corresponding uplink channel; wherein the state value of the Frequency hopping flag field corresponds one-to-one to the frequency hopping mode.

[0307] Specifically, multiple candidate frequency hopping modes may exist in multiple forms, such as a frequency hopping mode configured by two or more separate frequency hopping modes, such as {frequency hopping mode A, frequency hopping mode B}, or a composite configuration, such as {frequency hopping mode B and frequency hopping mode C} or {frequency hopping mode A, frequency hopping mode B and frequency hopping mode C}, wherein frequency hopping mode A, frequency hopping mode B and frequency hopping mode C respectively represent three different frequency hopping modes, any one of which can represent the first frequency hopping mode.

[0308] The network device configures the second DCI so that the terminal device selects a frequency hopping mode adopted by its corresponding uplink channel from multiple candidate frequency hopping modes according to the second DCI, as follows:

[0309] In the first indication field in the second DCI, each state value field in the first indication field corresponds to a frequency hopping mode one by one, and selecting different state values ​​determines the frequency hopping mode adopted by the corresponding uplink channel; for example, when the first indication field is a first candidate value, the terminal adopts a first frequency hopping mode; when the first indication field is a second candidate value, the terminal adopts a second frequency hopping mode; and so on;

[0310] Or, the Frequency hopping flag field is expanded in the second DCI, and the state value of the expanded Frequency hopping flag field corresponds to the frequency hopping mode one by one. For example, if it is expanded to 2 bits, there are 4 corresponding state values, each frequency hopping mode corresponds to a state value, and the hopping off state corresponds to a state value;

[0311] Or, in the Frequency hopping flag field in the second DCI, the state value of the Frequency hopping flag field is redefined, and the state value of the Frequency hopping flag field corresponds to the frequency hopping mode one by one. For example, when the state value of the Frequency hopping flag field in the second DCI is 0, the terminal device adopts the first frequency hopping mode; when the state value is 1, the terminal device adopts the second frequency hopping mode.

[0312] The frequency hopping indication method provided in the embodiment of the present application, when multiple frequency hopping modes are configured in the high-level signaling, determines the frequency hopping mode of the uplink channel corresponding to the terminal device through the state value in the second DCI. The state value of the second DCI can be determined by using the first indication field in the second DCI, the expanded Frequency hopping flag field, or the re-interpretation of the Frequency hopping flag field. Different state values ​​in each field correspond to different frequency hopping modes, so that the frequency hopping mode can be selected by selecting different state values.

[0313] It should be noted that the specific embodiments of the present invention applied to terminal equipment for illustrating the frequency hopping indication method are also applicable to network side equipment and can achieve the same technical effects, which will not be repeated here.
