Information transmission method, device and equipment

Abstract

The invention provides an information transmission method, device and equipment, and the information transmission method comprises the steps: transmitting first indication information and second indication information to a terminal; the first indication information is used for indicating time domain configuration information of the sub-band by taking a first indication period as an indication unit; the indication duration of the first indication information is greater than the duration of the first indication period; the second indication information is used for indicating the sub-band time domain position information in the first indication period. According to the scheme, the indication duration of the first indication information, the first indication period and the second indication information cooperate to support the configuration of the sub-band time domain position by taking a symbol as granularity according to the sub-band configuration period, so that the sub-band time domain position can be configured with larger granularity and longer period; therefore, the situation that the network equipment needs to be switched between the legacy TDD and the SBFD in each TDD configuration period is avoided, the switching frequency is reduced, and the problem that the network equipment is frequently switched between the legacy TDD and the SBFD due to a sub-band time domain position configuration scheme in the prior art is solved.

Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method, apparatus, and device. Background Art

[0002] To address the coverage, latency, and capacity issues of uplink transmission in the Time Division Duplex (TDD) mode, New Radio (NR) standardizes the non-overlapping sub-band full duplex feature. This feature divides the frequency domain resources into multiple non-overlapping sub-bands, with the uplink and downlink frequency domain resources located in different sub-bands. This feature is referred to as full duplex in the following text.

[0003] However, to match the existing TDD configuration period, the existing subband time domain position is configured based on the TDD configuration period and at a symbol granularity. This approach potentially requires the base station to switch between legacy TDD and subband full duplex (SBFD) within each TDD configuration period. Furthermore, because the base station may need to tune subbands or digital filters, change transmit and receive links, or change sampling frequencies, switching between full-duplex symbols and legacy symbols requires time, which results in significant latency.

[0162] The following first introduces the contents involved in the solution provided in the embodiment of the present application.

[0163] Currently, the subband time domain positions are distributed periodically with a period T. The subband time domain positions are configured by indicating the symbols and / or time slots where the subbands are located within a period T. Hereinafter, the period T is referred to as the subband configuration period.

[0164] Based on the foregoing, embodiments of the present application provide an information transmission method, apparatus, and device to address the issue of frequent switching between legacy TDD and SBFD caused by subband time-domain location configuration schemes in the prior art. The method, apparatus, and device are based on the same patent application. Since the principles underlying the issues addressed by the method, apparatus, and device are similar, their implementations can be referenced in conjunction with each other, and any repetitions will be omitted.

[0165] The information transmission method provided in the embodiment of the present application is applied to network devices, such as Figure 2 As shown, including:

[0166] Step 21: Send first indication information and second indication information to the terminal; wherein, the first indication information is used to indicate the time domain configuration information of the subband with the first indication period as the indication unit; the indication duration of the first indication information is greater than the duration of the first indication period; the second indication information is used to indicate the subband time domain position information within the first indication period.

[0167] Among them, "taking the first indication period as the indication unit" can also be understood as taking the first indication period as the granularity, that is, indicating according to each first indication period; and / or, "subband time domain configuration information" can be used to indicate whether the subband time domain position information is valid, or whether there is a subband configuration, etc.; and / or, the second indication information can be used to indicate the specific configuration content within the first indication period; and / or, the first indication information can be reused according to the indication duration as a period; and / or, the first indication information and the second indication information can be transmitted together or separately (such as sent through the same signaling or different signaling); and / or, in this scheme, the final subband time domain configuration period may be the first indication period, or it may be the indication duration of the first indication information as a period, but is not limited to this.

[0168] The information transmission method provided in the embodiment of the present application sends first indication information and second indication information to the terminal; wherein, the first indication information is used to indicate the time domain configuration information of the subband with the first indication period as the indication unit; the indication duration of the first indication information is greater than the duration of the first indication period; the second indication information is used to indicate the subband time domain position information within the first indication period; it can support the configuration of the subband time domain position with a symbol as the granularity compared to the subband configuration period by utilizing the indication duration of the first indication information, the first indication period and the second indication information to configure the subband time domain position with a larger granularity and a longer period, thereby avoiding the need for the network device to switch between legacy TDD and SBFD in each TDD configuration period, reducing the number of switching times, and solving the problem in the prior art that the subband time domain position configuration scheme causes the network device to frequently switch between legacy TDD and SBFD.

[0169] The indication duration of the first indication information is configured by the network device or agreed upon by a protocol; and / or the duration of the first indication period is configured by the network device or agreed upon by a protocol, or the duration of the first indication period is determined based on a common time division duplex configuration period of the cell. This clarifies the configuration of the indication duration of the first indication information and / or the configuration of the duration of the first indication period.

[0170] In this embodiment of the present application, the subband time domain configuration information is used to indicate: a first indication period during which subband time domain position information is valid and / or a first indication period during which subband time domain position information is invalid, within each of the first indication periods included in the indication duration; wherein the subband time domain position information within each of the first indication periods included in the indication duration is determined based on the second indication information. This allows for providing the subband time domain position information within the first indication period to the terminal and indicates whether the subband time domain position information within each of the first indication periods included in the indication duration is valid, thereby assisting in determining the subband time domain position. This approach can be understood to include: indicating the subband time domain position information for all first indication periods included in the indication duration via the second indication information, and specifying which first indication period within the indication duration has valid subband time domain position information via the first indication information. Specifically, the second indication information may indicate the subband time domain position information for one first indication period, which is then applied across all first indication periods included in the indication duration, or the second indication information may separately indicate the subband time domain position information for each of the first indication periods included in the indication duration. The sub-band time domain position information of each first indication period may be the same or different, which is not limited here.

[0171] Furthermore, the information transmission method further includes: sending third indication information to the terminal; the third indication information is used to indicate: subband time-domain position information within a target indication period, the target indication period including: at least one of the first indication periods in which the first indication information indicates that the subband time-domain position information is invalid; wherein the third indication information and the first indication information are sent via the same signaling or different signaling. This allows for reconfiguration of the subband time-domain position information for the first indication period in which the first indication information indicates that the subband time-domain position information is invalid.

[0172] The optional time domain configuration information of the subband is used to indicate: the first indication period in which the subband configuration exists and / or the first indication period in which the subband configuration does not exist in each of the first indication periods included in the indication duration; wherein the second indication information is used to indicate: the subband time domain position information within the first indication period in which the subband configuration exists. This can support directly or indirectly indicating to the terminal that there is the first indication period in which the subband configuration exists, and indicating the corresponding subband time domain position information, to assist the terminal in determining the subband time domain position. Specifically, the second indication information can indicate the subband time domain position information of one first indication period, and then be applied in all first indication periods in which the subband configuration exists included in the indication duration, or the second indication information can separately indicate the subband time domain position information of each first indication period in which the subband configuration exists included in the indication duration.

[0173] In an embodiment of the present application, (1) the first indication information is indicated by a bitmap; wherein the first value in the bitmap is used to indicate that the subband time domain position information within the corresponding first indication period is valid, or is used to indicate that the subband configuration exists in the corresponding first indication period; the second value in the bitmap is used to indicate that the subband time domain position information within the corresponding first indication period is invalid, or is used to indicate that the subband configuration does not exist in the corresponding first indication period; or, (2) the first indication information is indicated by index information, wherein the index information is the index information of the first indication period of whether the subband time domain position information is valid or invalid, or the index information is the index information of the first indication period of whether the subband configuration exists or does not exist; or, (3) the first indication information It is indicated by the starting position information and the number of consecutive periods, or the ending position information and the number of consecutive periods; wherein the starting position information refers to the position information of the first first indication period in which the subband time domain position information is valid or invalid in the indication duration, or the starting position information refers to the position information of the first first indication period in which the subband configuration exists or does not exist in the indication duration; the number of consecutive periods refers to the number of consecutive first indication periods; the ending position information refers to the position information of the last first indication period in which the subband time domain position information is valid or invalid in the indication duration, or the ending position information refers to the position information of the last first indication period in which the subband configuration exists or does not exist in the indication duration. In this way, the indication of the first indication information can be realized in a diversified manner. Wherein, for method (1), the correspondence between the bits in the bitmap and the first indication period is predefined or configured by the network device; for example, the correspondence between multiple bits and multiple first indication periods (such as the correspondence between 10 bits and 10 first indication periods); specifically, for example: the predefined highest bit (or lowest bit) corresponds to the first first indication period in the indication duration of the first indication information, etc., which is not limited here.

[0174] The indication duration is an integer multiple of the duration of the first indication period; and / or the first indication information, the second indication information, and the third indication information are cell-specific or terminal-specific. This support solution is more applicable to various practical scenarios.

[0175] The embodiment of the present application also provides an information transmission method, which is applied to a terminal, such as Figure 3 As shown, including:

[0176] Step 31: Receive first indication information and second indication information sent by a network device; wherein the first indication information is used to indicate time domain configuration information of a subband using a first indication period as an indication unit; the indication duration of the first indication information is greater than the duration of the first indication period; and the second indication information is used to indicate time domain position information of the subband within the first indication period;

[0177] Step 32: Determine the subband time domain position based on the first indication information and the second indication information. This step may include: determining the subband time domain position information within the indicated duration based on the first indication information and the second indication information; and determining the subband time domain position based on the subband time domain position information within the indicated duration. Determining the subband time domain position based on the subband time domain position information within the indicated duration may include: repeatedly applying the subband time domain position information within the indicated duration to obtain the subband time domain position; that is, the subband time domain position is obtained by repeatedly applying the subband time domain position information within the indicated duration with the indicated duration as a period, but is not limited thereto.

[0178] Among them, "taking the first indication period as the indication unit" can also be understood as taking the first indication period as the granularity, that is, indicating according to each first indication period; and / or, "subband time domain configuration information" can be used to indicate whether the subband time domain position information is valid, or whether there is a subband configuration, etc.; and / or, the second indication information can be used to indicate the specific configuration content within the first indication period; and / or, the first indication information can be reused according to the indication duration as a period; and / or, the first indication information and the second indication information can be transmitted together or separately (such as sent through the same signaling or different signaling); and / or, in this scheme, the final subband time domain configuration period may be the first indication period, or it may be the indication duration of the first indication information as a period, and / or, the subband time domain position information can indicate the specific location of the subband or indicate the position of the first symbol, and the first symbol refers to the symbol where the subband is located; but it is not limited to this.

[0179] The information transmission method provided in the embodiment of the present application is through receiving the first indication information and the second indication information sent by the network device; wherein, the first indication information is used to indicate the time domain configuration information of the subband with the first indication period as the indication unit; the indication duration of the first indication information is greater than the duration of the first indication period; the second indication information is used to indicate the subband time domain position information within the first indication period; the subband time domain position is determined according to the first indication information and the second indication information; it can support the use of the indication duration of the first indication information, the first indication period and the second indication information to collaborate to realize the configuration of the subband time domain position with the symbol as the granularity according to the subband configuration period. Compared with the configuration of the subband time domain position with the symbol as the granularity, this scheme configures the subband time domain position with a larger granularity and a longer period, thereby avoiding the network device from needing to switch between legacy TDD and SBFD in each TDD configuration period, reducing the number of switching times, and solving the problem that the subband time domain position configuration scheme in the prior art causes the network device to frequently switch between legacy TDD and SBFD.

[0180] Optionally, the subband time domain configuration information is used to indicate: a first indication period in which subband time domain position information is valid and / or a first indication period in which subband time domain position information is invalid, within each of the first indication periods included in the indication duration; wherein the subband time domain position information within each of the first indication periods included in the indication duration is determined based on the second indication information. This allows a terminal to obtain subband time domain position information within a first indication period and determine whether the subband time domain position information within each of the first indication periods included in the indication duration is valid, thereby assisting in determining the subband time domain position. This method may specifically include: obtaining subband time domain position information for all first indication periods included in the indication duration indicated by the second indication information; and determining, through the first indication information, which first indication period within the indication duration has valid subband time domain position information. Specifically, the second indication information may indicate the subband time domain position information for one first indication period, which is then applied to all first indication periods included in the indication duration, or the second indication information may separately indicate the subband time domain position information for each of the first indication periods included in the indication duration. The sub-band time domain position information of each first indication period may be the same or different, which is not limited here.

[0182] Furthermore, the information transmission method further includes: receiving third indication information sent by a network device; the third indication information is used to indicate: subband time domain position information within a target indication period, the target indication period including: at least one of the first indication periods in which the subband time domain position information indicated by the first indication information is invalid; the third indication information and the first indication information are sent via the same signaling or different signaling; determining the first subband time domain position based on the first indication information and the second indication information includes: determining the first subband time domain position based on the first indication information, the second indication information, and the third indication information; the first subband time domain position also including: the subband time domain position within the first indication period in which the subband time domain position information is invalid within the indication duration. This can further support obtaining the subband time domain position that is reconfigured for the first indication period in which the first indication information indicates that the subband time domain position information is invalid. Among them, determining the first sub-band time domain position information according to the first indication information and the second indication information may include: determining, according to the first indication information, the first indication period in which the sub-band time domain position information is valid, and the first indication period in which the sub-band time domain position information is invalid in each of the first indication periods included in the indication duration; determining, according to the second indication information, the sub-band time domain position within the first indication period in which the sub-band time domain position information is valid; determining, according to the third indication information, the sub-band time domain position within the first indication period in which the sub-band time domain position information is invalid; and obtaining the first sub-band time domain position based on the determined sub-band time domain position; but is not limited to this.

[0183] The time domain configuration information of the subband is used to indicate: the first indication period in which the subband configuration exists and / or the first indication period in which the subband configuration does not exist in each of the first indication periods included in the indication duration; and the second indication information is used to indicate: the subband time domain position information within the first indication period in which the subband configuration exists. This can support direct or indirect acquisition of the first indication period in which the subband configuration exists, and clarify the corresponding subband time domain position information to assist in determining the subband time domain position. Specifically, the second indication information can indicate the subband time domain position information of one first indication period, and then be applied in all first indication periods in which the subband configuration exists included in the indication duration, or the second indication information can separately indicate the subband time domain position information of each first indication period in which the subband configuration exists included in the indication duration.

In this way, the subband time domain position corresponding to the indication duration can be accurately obtained. Determining the second subband time domain position based on the first indication information and the second indication information may include: directly determining, based on the first indication information, a first indication period in which the subband configuration exists within each of the first indication periods included in the indication duration, or indirectly determining, based on the first indication information, a first indication period in which the subband configuration exists within each of the first indication periods included in the indication duration (for example, determining, based on the first indication information, a first indication period in which the subband configuration does not exist within each of the first indication periods included in the indication duration, and obtaining, based on the determination result, the first indication period in which the subband configuration exists); determining, based on the second indication information, the subband time domain position of the first indication period in which the subband configuration exists; and obtaining the second subband time domain position based on the determined subband time domain position, but the present invention is not limited thereto.

[0185] The indication duration of the first indication information is configured by the network device or agreed upon by a protocol; and / or the duration of the first indication period is configured by the network device or agreed upon by a protocol, or the duration of the first indication period is determined based on a common time division duplex configuration period of the cell. This clarifies the configuration of the indication duration of the first indication information and / or the configuration of the duration of the first indication period.

[0187] The indication duration is an integer multiple of the duration of the first indication period; and / or the first indication information, the second indication information, and the third indication information are cell-specific or terminal-specific. This support solution is more applicable to various practical scenarios.

[0192] Solution 1-1: For a subband configuration period indicated as invalid by the first indication information, the subband configuration in the corresponding subband configuration period is invalidated, that is, the uplink subband configuration in the corresponding subband configuration period is canceled.

[0193] For the subband configuration period in which the subband configuration is invalid, the symbol type within the subband configuration period (which can be understood as the subband time domain position) can be determined according to TDD-UL-DL-ConfigCommon (TDD uplink and downlink common configuration), TDD-UL-DL-ConfigDedicated (TDD uplink and downlink dedicated configuration) and / or SFI (Slot Format Indication) according to current rules.

[0194] Scheme 1-2: For the subband configuration period indicated as invalid by the first indication information, the uplink subband configuration on the subband configuration period is further indicated (via the third indication information), that is, the subband configuration within the subband configuration period is reconfigured; corresponding to the above-mentioned sending of the third indication information to the terminal; the third indication information is used to indicate: the subband time domain position information within the target indication period, and the target indication period includes: at least one of the first indication periods in which the subband time domain position information indicated by the first indication information is invalid.

For the first indication period with a subband configuration, the subband time domain position is further indicated (through the second indication information); the time domain configuration information corresponding to the above-mentioned subband is used to indicate: the first indication period with a subband configuration and / or the first indication period without a subband configuration in each of the first indication periods included in the indication duration; wherein, the second indication information is used to indicate: the subband time domain position information within the first indication period where a subband configuration exists.

[0197] Furthermore, in this plan:

[0204] The following is a detailed description of each solution involved in the embodiments of the present application.

[0205] Example 1 (corresponding to the above scheme 1-1):

[0206] The UE receives the second indication information sent by the base station, where the second indication information indicates the subband time domain position information within the subband configuration period (corresponding to the above-mentioned first indication period) with symbol granularity. The subband time domain position information indicated by the second indication information can be repeated with the subband configuration period as a period, and the subband configuration period is a period configured by the base station.

[0207] The UE receives first indication information sent by the base station; the first indication information indicates, at a subband configuration period granularity, whether the subband configuration of the subband configuration period is valid within a second indication period; the second indication period is a period configured by the base station. For a subband configuration period in which the subband configuration is invalid, the subband configuration determined according to the second indication information in the subband configuration period is invalidated, i.e., the uplink subband configuration in the subband configuration period is canceled; and / or if one or more subband configuration periods are indicated to be valid, the subband configuration determined according to the second indication information in the subband configuration period is valid.

[0208] For a subband configuration period in which subband configuration is invalid, the symbol type within the subband configuration period may be determined according to TDD-UL-DL-ConfigCommon, TDD-UL-DL-ConfigDedicated and / or SFI in accordance with current regulations.

[0209] Optionally, the duration of the second indication period is an integer multiple of the duration of the subband configuration period, for example, the duration of the second indication period is equal to 10 times the duration of the subband configuration period.

[0210] Optionally, the first indication information and the second indication information may be cell-specific, and may support cell-level cancellation of subband configurations within a partial subband configuration period; or they may be UE-specific, and may support cancellation of subband configurations within a partial subband configuration period for only some UEs.

[0211] Optionally, the specific indication method of the first indication information may include at least one of the following:

[0212] (1) It can be indicated by a bitmap, for example: when the bit indication of the corresponding subband configuration period is 0, it means that the subband configuration in the subband configuration period is valid; if the indication is 1, it means that the subband configuration in the subband configuration period is invalid; and vice versa. Figure 4 As shown in the figure, the time domain position of the subband within the subband configuration period is indicated by X in the figure. The duration of the second indication period is equal to the duration of 10 subband configuration periods. The bits of the 1st to 5th and 8th to 10th subband configuration periods indicate 0, indicating that the subband configuration in the corresponding subband configuration period is valid. The bits of the 6th to 7th subband configuration periods indicate 1, indicating that the subband configuration in the corresponding subband configuration period is invalid.

[0213] (2) It can be indicated by indicating the index of the uplink subband configuration period that is effective / ineffective (i.e., valid or invalid), that is, the first indication information contains the subband configuration period index within the second indication period range, and the subband configuration within the subband configuration period corresponding to the index is effective or ineffective, and the subband configuration is determined according to the second indication information. For example Figure 5As shown, the subband time domain position within the subband configuration period is indicated by X in the figure, and the duration of the second indication period is equal to the duration of 10 subband configuration periods. The first indication information includes subband configuration period indices 5 and 6 (indices are numbered starting from 0), which means that the subband configurations within the 6th and 7th subband configuration periods are invalid (i.e., not effective), and the subband configurations within the 1st to 5th and 8th to 10th subband configuration periods are effective; or, it means that the subband configurations within the 6th and 7th subband configuration periods are effective, and the subband configurations within the 1st to 5th and 8th to 10th subband configuration periods are not effective, wherein the subband configurations are determined according to the second indication information (corresponding to the subband time domain position information within the first indication period being determined according to the second indication information).

[0214] (3) Indicate by indicating the starting period position and number of periods that are effective and / or ineffective within the second indication period. Figure 6 As shown, the time domain position of the subband within the subband configuration period is indicated by X in the figure, and the duration of the second indication period is equal to the duration of 10 subband configuration periods. The first indication information indicates (through the field Start = 5) that the starting effective or ineffective period position is the position corresponding to index 5 (indexes are numbered starting from 0), and (through the field Length = 2) the length (consecutive number) of the effective or ineffective period is 2, which means that the subband configuration within the 6th and 7th subband configuration periods is effective, and the subband configuration within the 1st to 5th and 8th to 10th subband configuration periods is not effective. Alternatively, it means that the subband configuration within the 6th and 7th subband configuration periods is not effective, and the subband configuration within the 1st to 5th and 8th to 10th subband configuration periods is effective. The subband configuration is determined according to the second indication information.

[0215] Example 2 (corresponding to the above scheme 1-2):

[0216] The UE receives the second indication information sent by the base station, where the second indication information indicates the subband time domain position information within the subband configuration period with a symbol granularity. The subband time domain position information indicated by the second indication information can be repeated with the subband configuration period as a period, and the subband configuration period is a period configured by the base station.

[0217] The UE receives first indication information sent by the base station; the first indication information indicates, at a subband configuration period granularity, whether the subband configuration of the subband configuration period is valid within a second indication period; the second indication period is a period configured by the base station. For a subband configuration period in which the subband configuration is invalid, the subband configuration determined according to the second indication information during the subband configuration period becomes invalid, i.e., the uplink subband configuration during the subband configuration period is canceled; and / or for a subband configuration period in which the subband configuration is valid, the subband configuration determined according to the second indication information during the subband configuration period becomes valid.

[0218] If the UE receives third indication information (the third indication information is used to indicate the subband time domain position information within the invalid subband configuration period), the UE determines the subband time domain position information within the invalid subband configuration period based on the third indication information. Optionally, the third indication information may indicate the subband time domain position information within each invalid subband configuration period respectively; or may indicate one subband time domain position information, and the subband time domain position information applies to all invalid subband configuration periods. The third indication information may indicate the subband time domain position information within the subband configuration period with a granularity of symbol or time slot.

[0219] For a subband configuration period in which subband configuration is invalid, the symbol type within the subband configuration period may be determined according to TDD-UL-DL-ConfigCommon, TDD-UL-DL-ConfigDedicated and / or SFI in accordance with current regulations.

[0220] Optionally, the duration of the second indication period is an integer multiple of the duration of the subband configuration period, for example, the duration of the second indication period is equal to 10 times the duration of the subband configuration period.

[0221] Optionally, the first indication information, the second indication information and the third indication information may be cell-specific, and may support cell-level cancellation of subband configuration within a partial subband configuration period; or they may be UE-specific, and support changing only the subband configuration within a partial subband configuration period of some UEs.

[0222] Optionally, the specific indication method of the first indication information can be found in the content of Example 1 and will not be repeated here.

[0223] Example 3 (corresponding to above-mentioned solution 2):

[0224] The UE receives first indication information sent by the base station, where the first indication information indicates whether there is a subband configuration within the second indication period, with the first indication period as the granularity; for one or more first indication periods indicating subband configuration, the subband time domain position within the first indication period may be further indicated by the second indication information, where the second indication period and the first indication period are periods configured by the base station. Optionally, the second indication information may indicate the subband time domain position information within each first indication period with subband configuration respectively; or may indicate one subband time domain position information, where the subband time domain position information applies to all first indication periods with subband configuration. The second indication information may indicate the subband time domain position information within the first indication period with a symbol or a time slot as the granularity.

[0225] Optionally, the duration of the second indication period is an integer multiple of the duration of the first indication period, for example, the duration of the second indication period is equal to 10 times the duration of the first indication period. The first indication period may be configured by the base station or a TDD configuration period.

[0226] In the embodiment of the present application, the first indication information, the second indication information, and the third indication information can be sent separately, or at least both can be sent through the same signaling, which is not limited here. It is noted that the relevant contents of the above examples can be referenced to each other, and the repeated parts will not be repeated.
