[0163] 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.

[0164] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0165] 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.

[0166] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made:

[0167] 1) Duplex mode

[0168] 5G NR supports time division duplexing (TDD) and frequency division duplexing (FDD). TDD and FDD refer to two duplex communication modes in mobile communication technology. The TDD mode transmits and receives at different times on the same frequency channel, i.e., the carrier, and distinguishes the uplink and downlink transmission resources by time; the FDD mode transmits and receives at the same time on different frequency channels, and distinguishes the uplink and downlink transmission resources by frequency.

[0169] For sub-band full-duplex systems, the sub-band configurations currently considered to be supported include the following two cases:

[0170] SBFD subband configuration #1 uses the {DUD} mode, that is, one SBFD time slot contains an uplink subband at the center of the carrier bandwidth and two downlink subbands on both sides of the carrier bandwidth;

[0171] SBFD subband configuration #2 uses the {DU} mode, that is, one SBFD timeslot contains one uplink subband on one side of the carrier bandwidth and one downlink subband on the other side of the carrier bandwidth.

[0172] 2) How to determine the dynamic PRG size in NR

[0173] NR supports dynamic determination of PRG size. When the UE supports the capability of dynamically determining the PRG size, the base station can indicate whether to use bundle size set (bundleSizeSet) 1 or bundleSizeSet2 through 1 bit in the downlink control information (Downlink Control Information, DCI), where the candidate values ​​of bundleSizeSet1 and bundleSizeSet2 are as follows:

[0174] ·bundleSizeSet1={n4, wideband, n2-wideband, n4-wideband}

[0175] ·bundleSizeSet2={n4, wideband}

[0176] Among them, n2 and n4 are set values, and wideband is the number of resources occupied by PDSCH in the frequency domain.

[0177] If the Physical Resource Block (PRB) bundling size indicator field of the DCI indicates bundleSizeSet1, then

[0178] If bundleSizeSet1=n4, then PRG size=n4

[0179] If bundleSizeSet1=wideband, then PRG size=wideband

[0180] If bundleSizeSet1=n2-wideband, then

[0181] o If the number of consecutive PRBs scheduled by the UE>(BWP size) / 2, then PRG size=wideband; otherwise, PRG size=n2.

[0182] If bundleSizeSet1=n4-wideband, then

[0183] o If the number of consecutive PRBs scheduled by the UE>(BWP size) / 2, then PRG size=wideband; otherwise, PRG size=n4.

[0184] If the PRB bundling size indicator field of the DCI indicates bundleSizeSet2, then

[0185] If bundleSizeSet2=n4, then PRG size=n4

[0186] If bundleSizeSet2=wideband is configured, then PRG size=wideband.

[0187] However, for the SBFD subband configuration of {DUD}, if PDSCH cannot be transmitted across two discontinuous downlink subbands, the base station can only schedule it within one downlink subband, and the bandwidth of a downlink subband may always be less than half of the BWP bandwidth, resulting in the continuous resource blocks (RB) of PDSCH never being larger than half of the downlink BWP bandwidth. Therefore, when bundleSizeSet1 is configured as n2-wideband or n4-wideband, it cannot be implicitly determined as wideband; if PDSCH is supported to be transmitted across two discontinuous subbands, it is necessary to determine how to implicitly determine the PRG size in the case of two discontinuous RB resource allocations.

[0188] The embodiment of the present application provides a relay link connection control method and device. The method and device are based on the same application concept. Since the method and device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0189] like Figure 1 As shown, the method for determining the size of a physical resource group provided in an embodiment of the present application includes:

[0190] Step 101, when a dynamic physical resource group PRG is configured, the terminal determines the PRG size according to a physical downlink shared channel PDSCH transmission parameter;

[0191] The PDSCH transmission parameter includes at least one of the following:

[0192] The number of scheduled PDSCH symbols;

[0193] The number of PDSCH resource blocks (RBs) scheduled on the downlink subband.

[0194] In this way, the method for determining the size of the physical resource group of an embodiment of the present application, when applied to a terminal, can determine the PRG size according to the PDSCH transmission parameters (i.e., at least one of the number of scheduled PDSCH symbols and the number of PDSCH RBs scheduled on the downlink subband) for a case where a dynamic PRG is configured, thereby determining the PRG size in the SBFD time slot or symbol and ensuring the flexibility of determining the dynamic PRG size.

[0195] Optionally, in this embodiment, the method further comprises:

[0196] The terminal determines the PRG size according to the reference information and the transmission parameter of the PDSCH; wherein the reference information includes at least one of the following:

[0197] Threshold value;

[0198] A first correspondence between the number of scheduled PDSCH symbols in the PDSCH transmission parameter and a candidate value in the configuration corresponding to the PRG indicated by the downlink control information DCI;

[0199] A second corresponding relationship between the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and a candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0200] Here, the parameter information is related information for determining the PRG size. The first corresponding relationship is actually the corresponding relationship between the number of scheduled PDSCH symbols and the candidate value, and the second corresponding relationship is actually the corresponding relationship between the number of scheduled PDSCH RBs on the downlink subband and the candidate value.

[0201] It should be noted that, in this embodiment, the configuration corresponding to the PRG indicated by the DCI includes multiple candidate values, which can be implemented by the PRB bundling size indicator field of the DCI indicating bundleSizeSet1 or bundleSizeSet2.

[0202] Optionally, in this embodiment, the method further comprises:

[0203] The terminal determines the PRG size based on the scheduled number of PDSCH symbols in the PDSCH transmission parameters and a threshold value in the reference information.

[0204] That is, for the number of scheduled PDSCH symbols, the terminal can compare it with the corresponding threshold value and determine the PRG size according to the comparison result.

[0205] Optionally, when the comparison result of the scheduled PDSCH symbol number and the threshold value is that the scheduled PDSCH symbol number is greater than the threshold value, the PRG size is determined to be the second candidate value in the configuration corresponding to the PRG indicated by the DCI; when the comparison result of the scheduled PDSCH symbol number and the threshold value is that the scheduled PDSCH symbol number is less than or equal to the threshold value, the PRG size is determined to be the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0206] That is to say, the terminal will compare the number of scheduled PDSCH symbols with the threshold value. If the number of scheduled PDSCH symbols is greater than the threshold value, the PRG size is determined to be the second candidate value; if the number of scheduled PDSCH symbols is less than or equal to the threshold value, the PRG size is determined to be the second candidate value.

[0207] Optionally, the threshold value is determined by the number of symbols contained in a time slot. In this case, the threshold value is used for comparison with the number of scheduled PDSCH symbols. Specifically, the threshold value may be equal to half of the number of symbols contained in a time slot.

[0208] Optionally, in this embodiment, the method further comprises:

[0209] The terminal determines the PRG size based on a first correspondence between the number of scheduled PDSCH symbols in the PDSCH transmission parameter and a candidate value in a configuration corresponding to the PRG indicated by the DCI;

[0210] Among them, the first corresponding relationship is:

[0211] If the number of scheduled PDSCH symbols is an odd number, the PRG size is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0212] If the number of scheduled PDSCH symbols is an even number, the PRG size is the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0213] That is, based on the number of scheduled PDSCH symbols and the first corresponding relationship, the terminal can determine the PRG size as the first candidate value when the number of scheduled PDSCH symbols is an odd number; and determine the PRG size as the second candidate value when the number of scheduled PDSCH symbols is an even number.

[0214] Optionally, in this embodiment, the first candidate value is one of the candidate values ​​of bundleSizeSet1 and bundleSizeSet2, for example, the first candidate value is wideband, and the second candidate value is n2 or n4; or the first candidate value is n2 or n4, and the second candidate value is wideband. Of course, the first candidate value and the second candidate value may also be preset specific values.

[0215] Optionally, in this embodiment, the method further comprises:

[0216] The terminal determines the first comparison result and / or the second comparison result based on the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and the threshold value in the reference information;

[0217] The terminal determines the PRG size based on the second corresponding relationship, and the first comparison result and / or the second comparison result.

[0218] That is, for the number of PDSCH RBs scheduled on the downlink subband, the first comparison result and / or the second comparison result is determined according to whether the PDSCH transmission is in one downlink subband or two downlink subbands, and then the PRG size is determined in combination with the second corresponding relationship.

[0219] Optionally, in this embodiment, the terminal determines the first comparison result and / or the second comparison result based on the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and the threshold value in the reference information, including:

[0220] In the case where the PDSCH transmission is within a downlink sub-band, the number of PDSCH resource blocks RB scheduled within a downlink sub-band is compared with the threshold value to determine the first comparison result; or,

[0221] In the case where the PDSCH transmission is in two downlink sub-bands, a total number obtained by adding the numbers of PDSCH RBs scheduled in the two downlink sub-bands is compared with the threshold value, or the numbers of PDSCH RBs scheduled in the two downlink sub-bands are compared with the threshold value respectively, or the number of PDSCH RBs scheduled in the target downlink sub-band in the two downlink sub-bands is compared with the threshold value to determine the second comparison result;

[0222] The target downlink subband is the downlink subband with the smallest or largest number of scheduled PDSCH RBs among the two downlink subbands.

[0223] That is, when PDSCH is transmitted in one downlink subband, the terminal will compare the number of PDSCH RBs scheduled in the downlink subband with the threshold value, and then determine the PRG size based on the comparison result. When PDSCH is transmitted in two downlink subbands, in one way, the terminal will compare the total number obtained by adding the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value, and then determine the PRG size based on the comparison result; or, the terminal will compare the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value respectively, and then determine the PRG size based on the comparison result; or, the terminal will compare the number of PDSCH RBs scheduled in the target downlink subband (the downlink subband with the smallest or largest number of scheduled PDSCH RBs) in the two downlink subbands with the threshold value, and then determine the PRG size based on the comparison result.

[0224] Optionally, in this embodiment, the second corresponding relationship includes at least one of the following:

[0225] When the first comparison result is that the number of PDSCH RBs scheduled in a downlink subband is greater than the threshold value, the PRG size is a first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0226] When the first comparison result is that the number of PDSCH RBs scheduled in a downlink subband is less than or equal to the threshold value, the PRG size is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0227] When the second comparison result is that the total number obtained by adding the numbers of PDSCH RBs scheduled in two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0228] When the second comparison result is that the total number obtained by adding the numbers of PDSCH RBs scheduled in two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0229] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0230] When the second comparison result is that the number of PDSCH RBs scheduled in each of the two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0231] When the second comparison result is that the number of PDSCH RBs scheduled in each of the two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0232] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0233] When the second comparison result is that the number of PDSCH RBs scheduled in the target downlink subband is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0234] When the second comparison result is that the number of PDSCH RBs scheduled in the target downlink subband is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0235] In this way, when PDSCH is transmitted in a downlink subband, the terminal compares the number of PDSCH RBs scheduled in the downlink subband with the threshold value, and when the first comparison result is that the number of scheduled PDSCH RBs is greater than the threshold value, determines the PRG size as the first candidate value; when the first comparison result is that the number of scheduled PDSCH RBs is less than or equal to the threshold value, determines the PRG size as the second candidate value.

[0236] When PDSCH is transmitted in two downlink subbands, the terminal compares the total number obtained by adding the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value, and when the second comparison result is that the total number is greater than the threshold value, determines the PRG size as the first candidate value; when the second comparison result is that the total number is less than or equal to the threshold value, determines the PRG size as the second candidate value.

[0237] When PDSCH is transmitted in two downlink sub-bands, the terminal compares the number of PDSCH RBs scheduled in the two downlink sub-bands with the threshold value respectively.

[0238] If the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is greater than the threshold, determining that the PRG size in each downlink subband is the first candidate value; or

[0239] When the second comparison result is that the numbers of PDSCH RBs scheduled in the two downlink sub-bands are both less than or equal to the threshold value, determining that the PRG size in each downlink sub-band is the second candidate value; or

[0240] When the second comparison result is that the numbers of PDSCH RBs scheduled in the two downlink sub-bands are both greater than the threshold value, determining that the PRG size in each downlink sub-band is the first candidate value; or

[0241] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink sub-bands is less than or equal to the threshold, it is determined that the PRG size in each downlink sub-band is the second candidate value.

[0242] Here, according to the above manner, in the case where PDSCH transmission is in two downlink subbands, the terminal can determine the same PRG size for the two downlink subbands.

[0243] When PDSCH is transmitted in two downlink subbands, the terminal compares the number of PDSCH RBs scheduled in the target downlink subband with the threshold value, and when the second comparison result is that the number of scheduled PDSCH RBs is greater than the threshold value, determines that the PRG size in each downlink subband is the first candidate value; when the second comparison result is that the number of scheduled PDSCH RBs is less than or equal to the threshold value, determines that the PRG size in each downlink subband is the second candidate value.

[0244] Optionally, in this embodiment, the second corresponding relationship includes at least one of the following:

[0245] The second comparison result is that when the number of PDSCH RBs scheduled in the first downlink subband is greater than the threshold value, the PRG size in the first downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI; when the number of PDSCH RBs scheduled in the second downlink subband is less than or equal to the threshold value, the PRG size in the second downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0246] That is, in the case where PDSCH is transmitted in two downlink subbands, the terminal determines, based on the comparison result corresponding to each downlink subband, that the PRG size in this downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI when the number of PDSCH RBs scheduled in this downlink subband is greater than the threshold value; and determines that the PRG size in this downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI when the number of PDSCH RBs scheduled in this downlink subband is less than or equal to the threshold value.

[0247] Therefore, when PDSCH is transmitted in two downlink subbands, the terminal can determine the respective PRG sizes for the two downlink subbands according to the comparison result between the number of PDSCH RBs scheduled in each downlink subband and the threshold value. At this time, the PRG sizes in the two downlink subbands can be the same or different. For example, if the number of PDSCH RBs scheduled in downlink subband 1 and downlink subband 2 is greater than the threshold value, the PRG sizes in the two downlink subbands are both the first candidate values; if the number of PDSCH RBs scheduled in downlink subband 1 is greater than the threshold value, and the number of PDSCH RBs scheduled in downlink subband 2 is less than the threshold value, the PRG size in downlink subband 1 is the first candidate value, and the PRG size in downlink subband 2 is the second candidate value.

[0248] First candidate value Second candidate value First candidate value First candidate value Optionally, the threshold value is determined by the downlink subband size; or, the threshold value is determined by the bandwidth of the bandwidth part BWP where the PDSCH is located, the uplink subband size and the guard interval size. At this time, the threshold value is used for comparison related to the number of PDSCH RBs scheduled in the downlink subband. Specifically, the threshold value can be equal to half of the downlink subband size (DL subband size); or, the threshold value can be equal to in, is the bandwidth of the BWP where the PDSCH is located, is the upstream subband size, is the size of the protection interval, and x is a preset value (such as 2 or 4).

[0249] Among them, x=2, the threshold value is applicable to when PDSCH is transmitted in two downlink subbands, and the terminal determines the PRG size by comparing the total number obtained by adding the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value; x=4, the threshold value is applicable to other methods.

[0250] Optionally, in this embodiment, the downlink subband size is the size of the downlink subband where the PDSCH is located; or,

[0251] The downlink subband size is the size of the downlink subband containing the largest or smallest number of RBs among the two downlink subbands.

[0252] That is, when the threshold value is determined by the DL subband size, the DL subband size may be the size of the downlink subband where the PDSCH is located; the DL subband size may also be the size of the downlink subband containing the largest number of RBs among the two downlink subbands, or the size of the downlink subband containing the smallest number of RBs among the two downlink subbands.

[0253] Optionally, in this embodiment, the downlink subband size is the number of consecutive RBs for downlink transmission contained in the activated downlink BWP;

[0254] The uplink subband size is the number of consecutive RBs for uplink transmission contained in the activated uplink BWP;

[0255] The guard interval size is the number of RBs of the guard interval included in the activated uplink or downlink BWP.

[0256] Optionally, the reference information is configured by Radio Link Control (RRC).

[0257] That is, the terminal receives the reference information configured by the network side by receiving the RRC message. Of course, the reference information can also be predefined or preconfigured in the terminal, and the terminal can use it to determine the PRG size without receiving the relevant message.

[0258] The following describes the application of the method in the embodiment of the present application in combination with specific scenarios:

[0259] Example 1: Figure 2 As shown, assuming that the terminal is configured with a dynamic PRG and the PRG bundleSizeSet ​​indicated by the DCI includes n2-wideband, the DL / UL BWP includes 100 RBs, each downlink subband includes 40 RBs, the uplink subband includes 10 RBs, and the guard interval includes 10 RBs (each continuous guard interval range is 5 RBs). At this time, for the case where PDSCH transmission is within a downlink subband, the terminal determines the PRG size by comparing the number of PDSCH resource block RBs scheduled in the downlink subband with the threshold value.

[0260] Case 1: The threshold value is half of the DL subband size, that is, 40 / 2 = 20 RBs. The terminal is scheduled to transmit PDSCH in a downlink subband of the SBFD symbol. PDSCH occupies 10 consecutive RBs in the frequency domain for transmission (that is, the number of PDSCH RBs scheduled in the downlink subband is 10). Therefore, since the number of RBs is less than the threshold value (10 < 20), the terminal uses 2 as the PRG size.

[0261] Case 2: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in a downlink subband of the SBFD symbol. PDSCH occupies 25 consecutive RBs in the frequency domain for transmission (that is, the number of PDSCH RBs scheduled in the downlink subband is 25). Therefore, since the number of RBs is greater than the threshold value (25>20), the terminal uses wideband as the PRG size.

[0262] Case 3: The threshold value is RBs, the rest are the same as case 1 or case 2;

[0263] Case 4: The RRC configuration threshold is 20 RBs, and the rest is the same as Case 1 or Case 2.

[0264] Example 2: Figure 3As shown, assuming that the terminal is configured with a dynamic PRG and the PRG bundleSizeSet ​​indicated by the DCI contains n2-wideband, the DL / UL BWP contains 100 RBs, of which the downlink subband where the PDSCH is located contains 30 RBs, the other downlink subband contains 50 RBs, the uplink subband contains 10 RBs, and the guard interval contains 10 RBs (each continuous guard interval range is 5 RBs). At this time, for the case where PDSCH transmission is in a downlink subband, the terminal determines the PRG size by comparing the number of PDSCH resource block RBs scheduled in the downlink subband with the threshold value.

[0265] Case 1: The threshold value is half of the downlink subband where the PDSCH is located, that is, 30 / 2=15 RBs. The terminal is scheduled to transmit PDSCH in a downlink subband of the SBFD symbol. The PDSCH occupies 10 consecutive RBs in the frequency domain for transmission (that is, the number of PDSCH RBs scheduled in the downlink subband is 10). Therefore, since the number of RBs is less than the threshold value (10<15), the terminal uses 2 as the PRG size.

[0266] Case 2: The threshold value is half of the downlink subband where the PDSCH is located, that is, 30 / 2=15 RBs. The terminal is scheduled to transmit PDSCH in a downlink subband of the SBFD symbol. The PDSCH occupies 30 consecutive RBs in the frequency domain for transmission (that is, the number of PDSCH RBs scheduled in the downlink subband is 30). Therefore, since the number of RBs is greater than the threshold value (30>15), the terminal uses wideband as the PRG size.

[0267] Case 3: The RRC configuration threshold is 20 RBs, and the rest is the same as case 1 or case 2;

[0268] Case 4: The threshold value is half of the size of the larger downlink subband, that is, 50 / 2=25, and the rest is the same as Case 1 or Case 2.

[0269] Example 3: Figure 4 As shown, assuming that the terminal is configured with a dynamic PRG and the PRG bundle size set indicated by the DCI includes n2-wideband, the DL / UL BWP includes 100 RBs, each downlink subband includes 40 RBs, the uplink subband includes 10 RBs, and the guard interval includes 10 RBs (each continuous guard interval range is 5 RBs). At this time, for the case where PDSCH transmission is in two downlink subbands, the terminal determines the PRG size by comparing the total number obtained by adding the number of PDSCH resource blocks RBs scheduled in the two downlink subbands with the threshold value.

[0270] Case 1: The threshold value is RBs, the terminal is scheduled to transmit PDSCH in two downlink subbands of SBFD symbols, and PDSCH occupies a total of 10 RBs in the frequency domain in the two downlink subbands for transmission (that is, the total number of PDSCH RBs scheduled in the two downlink subbands is 10). Therefore, since the number of RBs is less than the threshold value (10<40), the terminal uses 2 as the PRG size;

[0271] Case 2: The threshold value is RBs, the terminal is scheduled to perform PDSCH transmission in two downlink subbands of the SBFD symbol, and PDSCH occupies a total of 60 RBs in the frequency domain in the two downlink subbands for transmission (that is, the total number of PDSCH RBs scheduled in the two downlink subbands is 60). Therefore, since the number of RBs is greater than the threshold value (60>40), the terminal uses wideband as the PRG size.

[0272] Example 4: The same scenario as Example 3. In this case, for the case where PDSCH transmission is in two downlink subbands, the terminal determines the PRG size in each downlink subband by comparing the number of PDSCH resource blocks RBs scheduled in the two downlink subbands with the threshold value.

[0273] Case 1: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. PDSCH occupies 10 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 10), and 25 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 25). Since the number of RBs of PDSCH in downlink subband A is less than the threshold value (10<20), the terminal uses 2 as the PRG size in subband A; the number of RBs of PDSCH in downlink subband B is greater than the threshold value (25>20), the terminal uses wideband as the PRG size in subband B;

[0274] Case 2: The threshold value is RBs, and the rest are the same as case 1.

[0275] Example 5: Same scenario as Example 3. In this case, for the case where PDSCH transmission is in two downlink subbands, the terminal determines the PRG size in the two downlink subbands at the same time by comparing the number of PDSCH resource blocks RB scheduled in the two downlink subbands with the threshold value respectively.

[0276] Case 1: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. PDSCH occupies 10 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 10), and 25 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 25). Since the number of RBs of PDSCH in downlink subband B is greater than the threshold value, that is, there is a downlink subband in which the number of PDSCH RBs scheduled is greater than the threshold value, the terminal uses wideband as the PRG size in both downlink subbands.

[0277] Case 2: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. The PDSCH occupies 10 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 10), and occupies 15 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 15). Since the number of RBs of PDSCH in both downlinks is less than the threshold value, that is, the number of PDSCH RBs scheduled in each downlink subband in the two downlink subbands is less than the threshold value, the terminal uses 2 as the PRG size in both downlink subbands.

[0278] Case 3: The threshold value is RB, the rest are the same as case 1;

[0279] Case 4: The threshold value is RBs, and the rest are the same as case 2.

[0280] Example 6: Same scenario as Example 3. In this case, for the case where PDSCH transmission is in two downlink subbands, the terminal determines the PRG size in the two downlink subbands at the same time by comparing the number of PDSCH resource blocks RB scheduled in the two downlink subbands with the threshold value respectively.

[0281] Case 1: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. PDSCH occupies 10 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 10), and 25 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 25). Therefore, the number of RBs of PDSCH in downlink subband A is less than the threshold value, that is, there is a downlink subband in which the number of PDSCH RBs scheduled is less than the threshold value. In this case, the terminal uses 2 as the PRG size in both downlink subbands.

[0282] Case 2: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to perform PDSCH transmission in two downlink subbands of the SBFD symbol. The PDSCH occupies 25 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in the downlink subband A is 25), and occupies 25 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in the downlink subband B is 25). Therefore, the number of RBs of PDSCH in both downlinks is greater than the threshold value, that is, the number of PDSCH RBs scheduled in each downlink subband in the two downlink subbands is greater than the threshold value, then the terminal uses wideband as the PRG size in both downlink subbands;

[0283] Case 3: The threshold value is RB, the rest are the same as case 1;

[0284] Case 4: The threshold value is RBs, and the rest are the same as case 2.

[0285] Example 7: Same scenario as Example 3. In this case, for the case where PDSCH transmission is in two downlink subbands, the terminal determines the PRG size in the two downlink subbands at the same time by comparing the number of PDSCH resource blocks RBs scheduled in the target downlink subbands in the two downlink subbands with the threshold value.

[0286] Case 1: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. PDSCH occupies 10 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 10), and occupies 25 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 25). Therefore, the resources scheduled by PDSCH in downlink subband A (that is, downlink subband A is the target downlink subband) are small and less than the threshold value, that is, the number of PDSCH RBs scheduled in the target downlink subband is less than the threshold value, then the terminal uses 2 as the PRG size in both downlink subbands;

[0287] Case 2: The threshold value is half of the DL subband size, that is, 40 / 2=20 RBs. The terminal is scheduled to transmit PDSCH in two downlink subbands of the SBFD symbol. PDSCH occupies 25 RBs in one downlink subband A (that is, the number of PDSCH RBs scheduled in downlink subband A is 25), and occupies 30 RBs in the other downlink subband B (that is, the number of PDSCH RBs scheduled in downlink subband B is 30). Therefore, the resources scheduled by PDSCH in downlink subband A (that is, downlink subband A is the target downlink subband) are less but greater than the threshold value, that is, the number of PDSCH RBs scheduled in the target downlink subband is greater than the threshold value, then the terminal uses wideband as the PRG size in both downlink subbands;

[0288] Case 3: The threshold value is RB, the rest are the same as case 1;

[0289] Case 4: The threshold value is RBs, and the rest are the same as case 2.

[0290] Example 8: The same scenario as Example 1, Example 2 or Example 3. In this case, the terminal determines the PRG size by comparing the number of scheduled PDSCH symbols with the threshold value.

[0291] Case 1: The threshold value is half of the number of symbols in the time slot. The PDSCH transmission scheduled by the terminal occupies 8 OFDM symbols in the time domain. A time slot contains 14 OFDM symbols. Therefore, the number of OFDM symbols occupied by PDSCH transmission exceeds half of the number of symbols in the time slot. That is to say, the number of scheduled PDSCH symbols is greater than the threshold value. In this case, the terminal uses wideband as the PRG size.

[0292] Case 2: The threshold value is half of the number of symbols in the time slot. The PDSCH transmission scheduled by the terminal occupies 4 OFDM symbols in the time domain. A time slot contains 14 OFDM symbols. Therefore, the number of OFDM symbols occupied by PDSCH transmission is less than half of the number of symbols in the time slot, that is, the number of scheduled PDSCH symbols is less than the threshold value, then the terminal uses 2 as the PRG size.

[0293] Example 9: The same scenario as Example 1, Example 2 or Example 3. In this case, the terminal determines the PRG size by a preset condition, based on whether the number of scheduled PDSCH symbols is an even number or an odd number.

[0294] Case 1: If the PDSCH transmission scheduled by the terminal occupies 7 OFDM symbols in the time domain, therefore, the number of OFDM symbols occupied by PDSCH transmission (i.e., the number of scheduled PDSCH symbols) is an odd number, the terminal uses wideband as the PRG size; if the PDSCH transmission scheduled by the terminal occupies 8 OFDM symbols in the time domain, therefore, the number of OFDM symbols occupied by PDSCH transmission (i.e., the number of scheduled PDSCH symbols) is an even number, the terminal uses 2 as the PRG size;

[0295] Case 2: If the PDSCH transmission scheduled by the terminal occupies 7 OFDM symbols in the time domain, therefore, the number of OFDM symbols occupied by the PDSCH transmission is an odd number (that is, the number of scheduled PDSCH symbols), the terminal uses 2 as the PRG size; if the PDSCH transmission scheduled by the terminal occupies 8 OFDM symbols in the time domain, therefore, the number of OFDM symbols occupied by the PDSCH transmission (that is, the number of scheduled PDSCH symbols) is an even number, the terminal uses wideband as the PRG size.

[0296] In summary, the method of the embodiment of the present application, for the case where a dynamic PRG is configured in the SBFD system, when the PDSCH transmission is located in the SBFD symbol, if there are two downlink subbands in the BWP, the PRG size is determined based on the PDSCH transmission parameters and related parameter information, thereby ensuring the flexibility of determining the dynamic PRG size.

[0346] The device of the embodiment of the present application, for the case where a dynamic PRG is configured, can determine the PRG size according to the PDSCH transmission parameters (i.e., at least one of the number of scheduled PDSCH symbols and the number of PDSCH RBs scheduled on the downlink subband), thereby determining the PRG size in the SBFD time slot or symbol and ensuring the flexibility of dynamic PRG size determination.

[0347] It should be noted here that the above-mentioned device provided in the embodiment of the present application can implement all the method steps implemented in the above-mentioned method embodiment, and can achieve the same technical effect. The parts and beneficial effects of this embodiment that are the same as those in the method embodiment will not be described in detail here.

[0348] like Figure 6 As shown, the embodiment of the present application also provides a method for determining the size of a physical resource group, including:

[0349] Step 601, when a dynamic physical resource group PRG is configured, the network device determines the PRG size according to a physical downlink shared channel PDSCH transmission parameter;

[0350] The PDSCH transmission parameter includes at least one of the following:

[0351] The number of scheduled PDSCH symbols;

[0352] The number of PDSCH resource blocks (RBs) scheduled on the downlink subband.

[0353] In this way, the method for determining the size of the physical resource group of an embodiment of the present application is applied to a network side device (such as a base station). For the case where a dynamic PRG is configured, the PRG size can be determined according to the PDSCH transmission parameters (i.e., at least one of the number of scheduled PDSCH symbols and the number of PDSCH RBs scheduled on the downlink subband), thereby determining the PRG size in the SBFD time slot or symbol and ensuring the flexibility of determining the dynamic PRG size.

[0354] Optionally, the method further comprises:

[0355] The network device determines the PRG size according to the reference information and the transmission parameter of the PDSCH; wherein the reference information includes at least one of the following:

[0356] Threshold value;

[0357] A first correspondence between the number of scheduled PDSCH symbols in the PDSCH transmission parameter and a candidate value in the configuration corresponding to the PRG indicated by the downlink control information DCI;

[0358] A second corresponding relationship between the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and a candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0359] Here, the parameter information is relevant information for determining the size of the PRG.

[0360] Optionally, the method further comprises:

[0361] The network device determines the PRG size based on the scheduled number of PDSCH symbols in the PDSCH transmission parameters and a threshold value in the reference information.

[0362] That is, for the number of scheduled PDSCH symbols, the network device can compare it with the corresponding threshold value and determine the PRG size according to the comparison result.

[0363] Optionally, when the comparison result of the scheduled PDSCH symbol number and the threshold value is that the scheduled PDSCH symbol number is greater than the threshold value, the PRG size is determined to be the second candidate value in the configuration corresponding to the PRG indicated by the DCI; when the comparison result of the scheduled PDSCH symbol number and the threshold value is that the scheduled PDSCH symbol number is less than or equal to the threshold value, the PRG size is determined to be the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0364] That is to say, the network device will compare the number of scheduled PDSCH symbols with the threshold value. If the number of scheduled PDSCH symbols is greater than the threshold value, the PRG size is determined to be the second candidate value; if the number of scheduled PDSCH symbols is less than or equal to the threshold value, the PRG size is determined to be the second candidate value.

[0365] Optionally, the method further comprises:

[0366] The network device determines the PRG size based on a first correspondence between the number of scheduled PDSCH symbols in the PDSCH transmission parameter and a candidate value in a configuration corresponding to the PRG indicated by the DCI;

[0367] Among them, the first corresponding relationship is:

[0368] If the number of scheduled PDSCH symbols is an odd number, the PRG size is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0369] If the number of scheduled PDSCH symbols is an even number, the PRG size is the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0370] That is, based on the number of scheduled PDSCH symbols and the first corresponding relationship, the terminal can determine the PRG size as the first candidate value when the number of scheduled PDSCH symbols is an odd number; and determine the PRG size as the second candidate value when the number of scheduled PDSCH symbols is an even number.

[0371] Optionally, the method further comprises:

[0372] The network device determines the first comparison result and / or the second comparison result based on the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and the threshold value in the reference information;

[0373] The network device determines the PRG size based on the second corresponding relationship, and the first comparison result and / or the second comparison result.

[0374] Optionally, the network device determines the first comparison result and / or the second comparison result based on the number of PDSCH RBs scheduled on the downlink subband in the PDSCH transmission parameter and a threshold value in the reference information, including:

[0375] In the case where the PDSCH transmission is within a downlink sub-band, the number of PDSCH resource blocks RB scheduled within a downlink sub-band is compared with the threshold value to determine the first comparison result; or,

[0376] In the case where the PDSCH transmission is in two downlink sub-bands, a total number obtained by adding the numbers of PDSCH RBs scheduled in the two downlink sub-bands is compared with the threshold value, or the numbers of PDSCH RBs scheduled in the two downlink sub-bands are compared with the threshold value respectively, or the number of PDSCH RBs scheduled in the target downlink sub-band in the two downlink sub-bands is compared with the threshold value to determine the second comparison result;

[0377] The target downlink subband is the downlink subband with the smallest or largest number of scheduled PDSCH RBs among the two downlink subbands.

[0378] That is, when PDSCH is transmitted in one downlink subband, the network side device will compare the number of PDSCH RBs scheduled in the downlink subband with the threshold value, and then determine the PRG size based on the comparison result. When PDSCH is transmitted in two downlink subbands, in one way, the network side device will compare the total number obtained by adding the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value, and then determine the PRG size based on the comparison result; or, the network side device will compare the number of PDSCH RBs scheduled in the two downlink subbands with the threshold value respectively, and then determine the PRG size based on the comparison result; or, the network side device will compare the number of PDSCH RBs scheduled in the target downlink subband (the downlink subband with the smallest or largest number of scheduled PDSCH RBs) in the two downlink subbands with the threshold value, and then determine the PRG size based on the comparison result.

[0379] Optionally, the second corresponding relationship includes at least one of the following:

[0380] When the first comparison result is that the number of PDSCH RBs scheduled in a downlink subband is greater than the threshold value, the PRG size is a first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0381] When the first comparison result is that the number of PDSCH RBs scheduled in a downlink subband is less than or equal to the threshold value, the PRG size is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0382] When the second comparison result is that the total number obtained by adding the numbers of PDSCH RBs scheduled in two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0383] When the second comparison result is that the total number obtained by adding the numbers of PDSCH RBs scheduled in two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0384] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0385] When the second comparison result is that the number of PDSCH RBs scheduled in each of the two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0386] When the second comparison result is that the number of PDSCH RBs scheduled in each of the two downlink subbands is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0387] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0388] When the second comparison result is that the number of PDSCH RBs scheduled in the target downlink subband is greater than the threshold value, the PRG size in each downlink subband is the first candidate value in the configuration corresponding to the PRG indicated by the DCI;

[0389] When the second comparison result is that the number of PDSCH RBs scheduled in the target downlink subband is less than or equal to the threshold value, the PRG size in each downlink subband is a second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0390] In this way, when PDSCH is transmitted in a downlink subband, the network device compares the number of PDSCH RBs scheduled in the downlink subband with the threshold value, and when the first comparison result is that the number of scheduled PDSCH RBs is greater than the threshold value, determines the PRG size as the first candidate value; when the first comparison result is that the number of scheduled PDSCH RBs is less than or equal to the threshold value, determines the PRG size as the second candidate value.

[0391] When PDSCH is transmitted in two downlink sub-bands, the network device compares the total number obtained by adding the number of PDSCHRBs scheduled in the two downlink sub-bands with the threshold value, and when the second comparison result is that the total number is greater than the threshold value, determines that the PRG size is the first candidate value; when the second comparison result is that the total number is less than or equal to the threshold value, determines that the PRG size is the second candidate value.

[0392] When PDSCH is transmitted in two downlink sub-bands, the network device compares the number of PDSCHRBs scheduled in the two downlink sub-bands with the threshold value respectively.

[0393] If the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink subbands is greater than the threshold, determining that the PRG size in each downlink subband is the first candidate value; or

[0394] When the second comparison result is that the numbers of PDSCH RBs scheduled in the two downlink sub-bands are both less than or equal to the threshold value, determining that the PRG size in each downlink sub-band is the second candidate value; or

[0395] When the second comparison result is that the numbers of PDSCH RBs scheduled in the two downlink sub-bands are both greater than the threshold value, determining that the PRG size in each downlink sub-band is the first candidate value; or

[0396] When the second comparison result is that the number of PDSCH RBs scheduled in one of the two downlink sub-bands is less than or equal to the threshold, it is determined that the PRG size in each downlink sub-band is the second candidate value.

[0397] Here, according to the above manner, in the case where PDSCH transmission is in two downlink sub-bands, the network device can determine the same PRG size for the two downlink sub-bands.

[0398] When PDSCH is transmitted in two downlink sub-bands, the network device compares the number of PDSCH RBs scheduled in the target downlink sub-band with the threshold value, and when the second comparison result is that the number of scheduled PDSCH RBs is greater than the threshold value, determines that the PRG size in each downlink sub-band is the first candidate value; when the second comparison result is that the number of scheduled PDSCH RBs is less than or equal to the threshold value, determines that the PRG size in each downlink sub-band is the second candidate value.

[0399] Optionally, in this embodiment, the second corresponding relationship includes at least one of the following:

[0400] The second comparison result is that when the number of PDSCH RBs scheduled in the first downlink subband is greater than the threshold value, the PRG size in the first downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI; when the number of PDSCH RBs scheduled in the second downlink subband is less than or equal to the threshold value, the PRG size in the second downlink subband is the second candidate value in the configuration corresponding to the PRG indicated by the DCI.

[0401] Therefore, when PDSCH is transmitted in two downlink sub-bands, the network device can determine the respective PRG sizes for the two downlink sub-bands according to the comparison result between the number of PDSCH RBs scheduled in each downlink sub-band and the threshold value. At this time, the PRG sizes in the two downlink sub-bands can be the same or different. For example, if the number of PDSCH RBs scheduled in downlink sub-band 1 and downlink sub-band 2 are both greater than the threshold value, the PRG sizes in the two downlink sub-bands are both the first candidate values; if the number of PDSCH RBs scheduled in downlink sub-band 1 is greater than the threshold value, and the number of PDSCH RBs scheduled in downlink sub-band 2 is less than the threshold value, the PRG size in downlink sub-band 1 is the first candidate value, and the PRG size in downlink sub-band 2 is the second candidate value.

[0402] Optionally, the threshold value is determined by the number of symbols contained in a time slot. In this case, the threshold value is used for comparison with the number of scheduled PDSCH symbols. Specifically, the threshold value may be equal to half of the number of symbols contained in a time slot.

[0403] Optionally, the threshold value is determined by the downlink subband size; or, the threshold value is determined by the bandwidth of the bandwidth part BWP where the PDSCH is located, the uplink subband size and the guard interval size. In this case, the threshold value is used for comparison with the number of PDSCH RBs scheduled in the downlink subband. Specifically, the threshold value can be equal to half of the downlink subband size (DL subband size); or, the threshold value can be equal to in, is the bandwidth of the BWP where the PDSCH is located, is the upstream subband size, is the size of the protection interval, and x is a preset value (such as 2 or 4).

[0404] Among them, x=2, the threshold value is applicable to when PDSCH is transmitted in two downlink sub-bands, and the network side device determines PRGsize by comparing the total number obtained by adding the number of PDSCH RBs scheduled in the two downlink sub-bands with the threshold value; x=4, the threshold value is applicable to other methods.

[0405] Optionally, in this embodiment, the downlink subband size is the size of the downlink subband where the PDSCH is located; or,

[0406] The downlink subband size is the size of the downlink subband containing the largest or smallest number of RBs among the two downlink subbands.

[0407] That is, when the threshold value is determined by the DL subband size, the DL subband size may be the size of the downlink subband where the PDSCH is located; the DL subband size may also be the size of the downlink subband containing the largest number of RBs among the two downlink subbands, or the size of the downlink subband containing the smallest number of RBs among the two downlink subbands.

[0408] Optionally, in this embodiment, the downlink subband size is the number of consecutive RBs for downlink transmission contained in the activated downlink BWP;

[0409] The uplink subband size is the number of consecutive RBs for uplink transmission contained in the activated uplink BWP;

[0410] The guard interval size is the number of RBs of the guard interval included in the activated uplink or downlink BWP.

[0411] Optionally, the reference information is predefined or preconfigured in the network side device. Of course, the network side device can also inform the terminal of the reference information through an RRC message so that the terminal can use it to determine the PRG size.
