[0022] The following, in combination with the accompanying drawings, describes in detail the transmission resource determination method and device provided in the embodiments of the present application through some embodiments and their application scenarios.

[0023] like Figure 2 As shown, an embodiment of the present application provides a transmission resource determination method 200, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0024] S202: The terminal determines at least one of the following according to the frequency domain resource type information on the time unit of the uplink transmission: whether to transmit the first uplink channel; and the frequency domain resource for transmitting the first uplink channel.

[0025] The uplink transmission mentioned in this step may be transmission of one or more transmission opportunities of a first uplink channel. The first uplink channel may be a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0026] The time unit mentioned in this step includes one of the following: symbol, slot, sub-slot, sub-frame. For example, the time unit may be at least one symbol, at least one slot, at least one sub-slot, or at least one sub-frame.

[0027] The above-mentioned frequency domain resource type information may include frequency domain resource transmission direction information, and the frequency domain resource transmission direction information may include at least one of the following: downlink (D), uplink (U), flexible (flexible, F), guard band (guardband), etc.

[0028] Before S202, the terminal may also receive indication information, which is used to indicate frequency domain resource type information, for example, indicating frequency domain resource transmission direction information. The indication information may be high-level signaling, Media Access Control-Control Element (MAC CE) signaling, or downlink control information (DCI).

[0029] The granularity determined by the frequency domain resource type information may be a subband. A subband may include one or more resource blocks (RBs). The one or more resource blocks may also be referred to as a resource block set (RB set).

[0030] It should be noted that the subband mentioned in each embodiment of the present application may represent a plurality of continuous RBs, and therefore, the subband may also be described by an RB set.

[0031] The guard band mentioned in each embodiment of the present application represents a frequency domain resource where the terminal does not send or receive signals / channels. The frequency domain resource can be described by the number of RB / resource elements (RE), the position of RB / RE, or a frequency range.

[0032] It should also be noted that for different time units (such as slot / symbol / subframe), the direction configuration of the subband may be different, and the size of the subband may also be different.

[0033] To explain the above sub-band, time unit and frequency domain resource transmission direction information in detail, the following will be combined with Figure 3 and Figure 4 These two specific examples are used to illustrate this.

[0034] like Figure 3 As shown, Figure 3 The diagram schematically shows a spectrum diagram when the network side device is flexible / full duplex. Figure 3 The symmetrical spectrum of Frequency Division Duplexing (FDD) can be semi-statically configured or dynamically indicated as downlink or uplink transmission in certain time units (such as slot / symbol).

[0035] In the third to fifth time units, the uplink spectrum is configured as downlink; in the sixth time unit, the downlink spectrum is configured as uplink. Figure 3 Two sub-bands are schematically shown, but in practice, the number of sub-bands is not limited thereto. In addition, in the frequency domain direction, a guard band is provided between these sub-bands.

[0036] like Figure 4 As shown, Figure 4 The diagram schematically shows a spectrum diagram when the network side device is flexible / full duplex. Figure 4 For the asymmetric spectrum of Time Division Duplexing (TDD), different frequency domain resources on certain time units (such as slot / symbol) of TDD can be semi-statically configured or dynamically indicated to have both uplink transmission and downlink reception.

[0037] like Figure 4 As shown in the 3rd to 7th time units, there are both uplink sub-bands and downlink sub-bands in these 5 time units. Figure 4 Four sub-bands are schematically shown, but in fact, the number of sub-bands is not limited to this. In addition, in the frequency domain, guard bands can be set between these sub-bands. Figure 4 Guard bands are not shown.

[0038] Regarding the above-mentioned symmetric spectrum or asymmetric spectrum, before S202, the terminal may also receive indication information, which is used to notify the terminal of the transmission / reception direction on the time unit, i.e., which time slots / symbols; on the frequency, i.e., which sub-bands (sub-band), sub-carriers (sub-carrier), resource blocks (RB), i.e., uplink (U), downlink (D) or flexible (flexible, F), etc.

[0039] In this embodiment, the terminal can determine at least one of the following according to the frequency domain resource type information on the time unit of the uplink transmission: whether to transmit the first uplink channel; and the frequency domain resource for transmitting the first uplink channel. The terminal can be a half-duplex terminal.

[0040] For example, when it is determined that the first transmission resource of the uplink transmission overlaps with unavailable resources (such as downlink subband, flexible subband, protection band), the first transmission resource is considered to be an unavailable resource, and the first uplink channel is not transmitted on the first transmission resource.

[0041] For another example, when it is determined that the first transmission resource for the uplink transmission is an available transmission resource, the first transmission resource is considered to be an available frequency domain resource, and the first uplink channel is transmitted on the first transmission resource.

[0042] Optionally, S202 may also include the following steps: when the frequency domain resources for transmitting the first uplink channel are determined, the first uplink channel may also be transmitted through the determined frequency domain resources; and / or, when the frequency domain resources for transmitting the first uplink channel are determined, the first uplink channel may also be transmitted, for example, by transmitting the first uplink channel through the determined frequency domain resources.

[0043] In this embodiment, the terminal can determine the transmission resources of the first uplink channel based on the uplink and downlink configuration information of the subband, so that when the frequency domain resources are not used for uplink transmission, the transmission behavior of the terminal is determined, including whether to transmit the first uplink channel, or determine new transmission resources for the first uplink channel, so that the scheduling of the network side equipment is more flexible and the transmission behavior of the terminal is clearer, so as to facilitate obtaining better transmission performance.

[0044] The transmission resource determination method provided in the embodiment of the present application can enable the terminal to determine whether to transmit the first uplink channel and / or the frequency domain resources for transmitting the first uplink channel according to the frequency domain resource type information on the time unit of the uplink transmission, thereby solving the problem that the terminal cannot perform uplink channel transmission, affecting communication efficiency, and facilitating improving communication efficiency.

[0045] In embodiment 200, it is mentioned that the terminal can determine at least one of the following according to the frequency domain resource type information on the time unit of the uplink transmission: whether to transmit the first uplink channel; and the frequency domain resource for transmitting the first uplink channel. For detailed description, several specific examples will be used for illustration.

[0046] Example 1 The terminal mentioned in Example 200 determines whether to transmit the first uplink channel based on the frequency domain resource type information on the time unit of the uplink transmission, including: the terminal does not transmit the first uplink channel on the first transmission resource if it is determined that the first transmission resource of the uplink transmission overlaps with the unavailable resource based on the frequency domain resource type information on the time unit of the uplink transmission.

[0047] The unavailable resources may include at least one of the following: resources in a downlink subband; resources in a flexible subband; and resources in a protection band.

[0048] Optionally, the first uplink channel is repeatedly transmitted N times, where N is an integer greater than or equal to 2, for example, N=4. The method provided in embodiment 200 may further include one of the following 1) to 3).

[0049] 1) The first transmission resource is not considered as a valid transmission resource, and the transmission resource of the first uplink channel is continued to be determined until N transmission resources are determined. The difference between this example and the following 2) is that in this example, even if the transmission resource is determined, it does not necessarily mean that N transmissions are completed, and transmission may not be performed due to other factors.

[0050] 2) Continue to determine the transmission resources of the first uplink channel, and complete N repeated transmissions of the first uplink channel. The difference between this example and the above 1) is that in this example, the transmission resources are determined to complete N repeated transmissions.

[0051] 3) If N available transmission resources do not appear or N repeated transmissions are not completed within a preset time period after the first transmission of the first uplink channel, the remaining transmission of the first uplink channel is not performed. The remaining transmission may be the transmission that is not completed within the preset time period, for example, if N=4, 3 available transmission resources appear or 3 repeated transmissions are completed within the preset time period, then the last transmission is not performed.

[0052] Example 2 The terminal mentioned in embodiment 200 determines, according to the frequency domain resource type information on the time unit of the uplink transmission, the frequency domain resource for transmitting the first uplink channel, including at least one of the following 1) and 2): 1) The terminal determines at least one available subband according to frequency domain resource type information on a time unit of uplink transmission; and determines a subband for transmitting the first uplink channel according to the at least one available subband. The available subband may be an uplink subband.

[0053] In this example, when the number of at least one available subband is 1, this one available subband is directly used as the subband for transmitting the first uplink channel; when the number of at least one available subband is greater than 1, the terminal can also select a subband for transmitting the first uplink channel, for example, select the subband with the lowest frequency domain position as the subband for transmitting the first uplink channel.

[0054] 2) The terminal determines the type of each subband in the subband set (such as uplink, downlink, etc.) according to the frequency domain resource type information on the time unit of the uplink transmission, and determines the frequency domain resources for transmitting the first uplink channel according to the type of each subband in the subband set, wherein the frequency domain resources of the combination of at least one subband type of the subband set are configured by the network side device.

[0055] The subband set in this example is Figure 4 As shown in the subbands in the 3rd to 7th time units, the subband sets in these 5 time units each include 4 subbands.

[0056] Optionally, the determination of the subband for transmitting the first uplink channel according to the at least one available subband mentioned in 1) above includes at least one of the following: determining the subband for transmitting the first uplink channel according to the index value of the at least one available subband; determining the subband for transmitting the first uplink channel according to the frequency domain position of the at least one available subband.

[0057] Optionally, the subband for transmitting the first uplink channel has the lowest or highest index value among the at least one available subband; and / or the subband for transmitting the first uplink channel has the lowest or highest frequency among the at least one available subband.

[0058] Example 3 The terminal mentioned in Embodiment 200 determines, based on the frequency domain resource type information on the time unit of the uplink transmission, that the frequency domain resource for transmitting the first uplink channel includes at least one of the following 1) and 2).

[0059] 1) selecting an available frequency domain resource allocation (FDRA) configuration according to frequency domain resource type information on a time unit of uplink transmission; determining a frequency domain resource for transmitting the first uplink channel according to the available FDRA configuration; wherein the first uplink channel includes a PUSCH.

[0060] Optionally, the available FDRA configuration is the one with the lowest or highest index value among multiple FDRA configurations, wherein the network side device configures or indicates multiple FDRA configurations for the terminal.

[0061] 2) Selecting available PUCCH resources according to frequency domain resource type information on a time unit of uplink transmission, wherein the first uplink channel includes the PUCCH.

[0062] Optionally, the available PUCCH resource is the one with the lowest or highest index value among multiple PUCCH resources, wherein the network side device configures or indicates multiple PUCCH resources for the terminal.

[0063] Example 4 The terminal mentioned in embodiment 200 determines the frequency domain resources for transmitting the first uplink channel according to the frequency domain resource type information on the time unit of the uplink transmission, including: determining the frequency domain resources for transmitting the first uplink channel according to the frequency domain resource type information on the time unit of the uplink transmission and the indication of the FDRA domain.

[0064] Optionally, the size (number of bits) of the FDRA domain in the downlink control information (DCI) is determined based on available frequency domain resources, and the available frequency domain resources include one of the following 1) and 2): 1) Available subbands on the scheduled PUSCH transmission time resources. For example, the size of the FDRA domain is determined by the available subbands on the scheduled PUSCH transmission time resources (optionally, the transmission opportunity occasion of the first transmission). 2) The collection or intersection of available frequency domain resources in at least one time unit. For example, the collection or intersection of available frequency domain resources in at least one time unit is determined based on the subband / guard band resources indicated by the network side device.

[0065] Example 5 The first uplink channel is a frequency hopping transmission. The terminal mentioned in Embodiment 200 determines that the frequency domain resources for transmitting the first uplink channel include at least one of the following 1) and 2) based on the frequency domain resource type information on the time unit of the uplink transmission.

[0066] 1) The terminal determines the type of each subband in the subband set according to the frequency domain resource type information on the time unit of the uplink transmission, and determines the frequency domain resources for transmitting the first uplink channel according to the type of each subband in the subband set, wherein the frequency domain resources for the frequency hopping transmission of the combination of at least one subband type of the subband set are configured by the network side device.

[0067] For example, the network side device configures different first hop resources, second hop resources, etc. for different subband sets, and the terminal performs frequency hopping transmission on the corresponding 1st hop and 2nd hop according to the subband set corresponding to the current time unit.

[0068] 2) The terminal determines available frequency domain resources according to the frequency domain resource type information on the time unit of uplink transmission, and determines the frequency domain resources for transmitting the first uplink channel according to the available frequency domain resources. In this example, the terminal performs frequency hopping transmission based on the available frequency domain resources.

[0069] Example 6 The first uplink channel is frequency hopping transmission, and the method of the embodiment 200 further includes: according to the frequency domain resource type information on the time unit of the uplink transmission, when it is determined that the transmission resource of a transmission opportunity is an unavailable resource, not performing the frequency hopping transmission. For example, transmission is performed in a non-frequency hopping transmission mode.

[0070] The unavailable resources include at least one of the following: resources in a downlink subband; resources in a flexible subband, and resources in a protection band.

[0071] The transmission resource of the transmission opportunity is determined by the terminal based on each transmission or repeated transmission; or determined based on scheduled time domain resources.

[0072] In this example, a single transmission / repeated transmission for frequency hopping transmission includes at least one time unit, or the scheduled time domain resources include at least one time unit, and the terminal makes a judgment based on the at least one time unit when determining whether the frequency domain resources are available.

[0073] This example may also include the following steps: the terminal renumbers the available frequency domain resources according to the frequency domain resource type information on the time unit of the uplink transmission to obtain the renumbered available frequency domain resources; wherein the terminal determines the frequency domain resources for transmitting the first uplink channel according to the frequency domain resource type information on the time unit of the uplink transmission, including: determining the frequency domain resources for transmitting the first uplink channel according to the renumbered available frequency domain resources.

[0074] To explain in detail the transmission resource determination method provided in the embodiment of the present application, the following will be combined with Figures 5 to 9 These are described in detail with reference to several specific embodiments.

[0075] exist Figures 5 to 9 In the figure, the horizontal direction is the time domain direction, and the vertical direction is the frequency domain direction. The squares filled with diagonal lines represent uplink, and the squares filled with small black dots represent downlink. The time domain length of each square can be one time slot. Figures 5 to 9In , we can think of it as two time units (that is, 5 squares make up one time unit), or we can think of it as each square representing one time unit. Figures 5 to 9 In the frequency domain, it can be considered that there are 4 sub-bands, and the sub-bands are guard bands. The dotted box in the vertical direction can also be considered as a guard band.

[0076] Example 1 This embodiment determines the transmission subband, which corresponds to the embodiment 200 in which the terminal determines the frequency domain resources for transmitting the first uplink channel according to the frequency domain resource type information on the time unit of the uplink transmission.

[0077] like Figure 5 As shown, the network configures or instructs repeated transmission of the first uplink channel in multiple time units (such as slots), and the frequency domain transmission resource indicated by the network is in one of the subbands, and in the subsequent transmission time units, the transmission direction of the subband changes.

[0078] For example, Figure 5 If the third repeated transmission cannot be performed on the previous subband, the terminal will select the subband with the lowest subband index value or the lowest frequency for uplink transmission. Figure 5 Completed 4 transfers.

[0079] Or, in other examples, when the subband for uplink transmission is unavailable, the terminal does not perform the transmission, that is, does not transmit the third and fourth repeated transmissions.

[0080] Another way is that the terminal determines the transmission resources according to the configuration or instruction of the transmission resources of the network.

[0081] For example, for PUSCH, the network configures or indicates multiple resource allocation configurations (FDRA), and the terminal selects an available FDRA configuration for PUSCH transmission. Optionally, the FDRA configuration with the lowest index value among the available FDRA configurations is used. Figure 6 As shown, the available FDRA configurations are FDRA1 and FDRA2, and the terminal selects FDRA1 with the lowest index value for PUSCH transmission.

[0082] For PUCCH, the network configures or indicates multiple PUCCH resources, and the terminal selects the available PUCCH resource for transmission. Optionally, the PUCCH resource with the lowest index value is used. Figure 7 As shown, the available PUCCH resources are PUCCH resource 1 and PUCCH resource 2, and the terminal selects PUCCH 1 with the lowest index value for PUCCH transmission.

[0083] Another way is that the terminal does not change the frequency domain resource for transmission. If the frequency domain resource is not available, it continues to determine available time slots on the same frequency domain resource until N transmission resources are determined or N transmissions are completed.

[0084] Alternatively, the terminal determines the frequency domain resources for transmission according to the transmission delay. For example, within T time (corresponding to the preset time length in the previous embodiment) after the start time, N repeated transmissions can be completed, or N transmission resources are determined. Then the terminal uses Figure 8 The frequency domain resource determination method shown is to determine N transmission resources at the frequency domain position. Or, if N repeated transmissions cannot be completed within T time after the start time, or N transmission resources are not determined, the terminal determines the frequency domain resources using the above methods of this embodiment.

[0085] Example 2 This embodiment determines the frequency hopping mode.

[0086] In this embodiment, if the network configures or instructs the terminal to perform frequency hopping transmission, and the available uplink transmission resources in different time units change, the terminal needs to determine the transmission method in this case: One method is that the network configures first hop and second hop for different subband combinations respectively, and the terminal determines the transmission resources according to the subband combination currently being transmitted. For example, the network configures the starting RB idx of the 1st hop and the 2nd hop of [DLUL UL DL] to be M, N; and configures the starting RB idx of the 1st hop and the 2nd hop of [UL DL DL UL] to be P, Q. The terminal determines the frequency hopping transmission resources according to the current subband combination, as shown in the following example. Fig. 9 shown.

[0087] The second method is that if it is determined that the frequency hopping resources are not available, frequency hopping transmission is not performed, for example, the same frequency is used for transmission, or the method of embodiment 1 is used for transmission.

[0088] In another way, the network determines the resources for frequency hopping transmission based on the available subbands, for example, based on the available subband idx at the first time of the frequency hopping transmission, and the RB idx in the subband, to determine the frequency domain transmission resources for transmission at the second time. For example, if the available transmission resources at the first moment are {subband#2, RB_X}, {subband#3, RB_Y}, and Subband#2 / 3 are the first and second available subbands at the first time, then the terminal performs frequency hopping transmission at the first and second available subbands at the second time, namely {subband#1, RB_X} and {subband#4, RB_Y}.

[0089] Example 3 This embodiment performs RB renumbering based on available resources.

[0090] In this embodiment, the terminal renumbers the RB index (index) in the current available subband (such as uplink), and determines the transmission frequency domain resource of the PUSCH based on the renumbered available RB index.
