[0050] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0051] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0052] Full-duplex technology is considered one of the potential key technologies for 6G. However, the evolution from traditional TDD and FDD (Frequency Division Duplexing) duplexing to CCFD (Co-time Co-frequency Full Duplex) will not happen overnight. SBFD technology can be seen as a stage technology in the evolution from traditional duplexing technology to CCFD.
[0053] Full-duplex technology allows simultaneous uplink and downlink information transmission on the same frequency band. SBFD technology refers to the simultaneous transmission of uplink and downlink information on different TDD carriers within the same carrier or frequency band using non-overlapping frequency domain resources. For example, time resources on a TDD carrier other than the cell common uplink time resource—that is, the TDD common uplink / downlink configuration parameter TDD-UL-DL-ConfigCommon configured as downlink and / or flexible symbols—are divided into non-overlapping uplink and downlink sub-bands in the frequency domain, thus becoming SBFD time resources. Only one continuous uplink sub-band is allocated, which can be configured on the lower carrier frequency side, the higher carrier frequency side, or in the middle of the carrier frequency domain. Uplink information can be transmitted in the uplink sub-band within the SBFD time resource, while downlink information is transmitted in the downlink sub-band. The base station can simultaneously transmit and receive on the SBFD time resource, while the user equipment side maintains a mode of only transmitting or receiving. The aforementioned technologies can improve uplink coverage, increase uplink capacity, and reduce uplink transmission latency. Furthermore, compared to CCFD, they are beneficial for eliminating base station self-interference and mitigating cross-link interference, making them one of the hot topics in current 5G-A NR (New Radio) standard discussions. A schematic diagram of SBFD time resources and uplink / downlink subbands is shown below. Figure 1 As shown, the time resources include one or more of subframes, time slots, and symbols.
[0054] The frequency domain resources for user equipment to transmit uplink information also need to be within the user equipment's initial uplink BWP (Bandwidth Part) or active uplink BWP. Therefore, for user equipment aware of SBFD, resource blocks located in the initial uplink BWP or active uplink BWP in the uplink subband of the SBFD time resource can be used for uplink transmission, and are called uplink usable resource blocks (UL usable resource blocks).
[0055] In the existing NR standard protocol, PUSCH (Physical Uplink Shared Channel) and PUCCH (Physical Uplink Control Channel) support frequency diversity gain by using frequency hopping technology.
[0056] For PUSCH repetition type A and TBoMS (Transport Block processing over MultipleSlots), and PUSCH repetition type B, inter-slot frequency hopping can be used for transmission. For PUSCH inter-slot frequency hopping, when PUSCH DMRS (Demodulation Reference Signal) binding is enabled, and when the PUSCH is not scheduled in DCI (Downlink Control Information) format 0_0 scrambled by CRC (Cyclic Redundancy Check) using uplink grant carried by RAR (Random Access Response) or TC-RNTI (Temporary Cell Radio Network Temporary Identifier), frequency hopping can be performed in the time slot. The starting resource block for PUSCH is:
[0057]
[0058] In formula (1), It is the current timeslot number within the system's radio frame, N FH It is the PUSCH frequency hopping interval configured by the base station for the user equipment. RBstart is the starting resource block index within the uplink BWP, indicated by the resource block allocation information in the DCI. offset It is the number of resource blocks in the frequency domain offset between the two hops. This is the number of resource blocks contained in the initial uplink BWP or the activated uplink BWP.
[0059] For PUCCH, inter-slot frequency hopping can also be used. The PUCCH resource information elements configured by the base station for the user equipment include the starting resource block index parameter startingPRB before frequency hopping and the starting resource block index parameter secondHopPRB after frequency hopping. When PUCCH is repeatedly transmitted, if the user equipment is configured to perform inter-slot frequency hopping for the repeatedly transmitted PUCCH and PUCCH DMRS binding is enabled, the user equipment will start from the first time slot of the repeated PUCCH transmission, every One frequency hop in each consecutive time slot, This refers to the PUCCH frequency hopping interval configured by the base station for the user equipment. The first interval, starting from the first time slot of the repeated PUCCH transmission, is designated as interval 0, the second interval as interval 1, and so on. Even-numbered intervals use the PUCCH start resource block index startingPRB, while odd-numbered intervals use the start resource block index secondHopPRB.
[0060] For base station-side SBFD supporting the same TDD carrier, if the frequency hopping method of PUSCH and PUCCH in the existing NR standard protocol is directly applied, the existing NR considers the uplink available frequency domain resources for all time resources within the initial uplink BWP or active uplink BWP, without considering the uplink subband for SBFD time resources. This may result in the starting resource block of PUSCH or PUCCH being located outside the uplink available resource block in the SBFD time resources.
[0061] For example, such as Figure 2 As shown, the PUSCH starting resource blocks in slots 6, 7, 12, and 13 are located outside the uplink available resource blocks.
[0062] It should be noted that, in Figure 2 In the figure, reference numeral 1001 indicates uplink subband, reference numeral 1002 indicates uplink active BWP, reference numeral 1003 indicates uplink available PRB (Physical Resource Block), and reference numeral 21 indicates RB. start Reference numeral 22 is used to indicate
[0063] To address the aforementioned issues, for PUCCH, current standard discussions support configuring the starting resource block index parameter `startingPRB` before frequency hopping and the starting resource block index parameter `secondHopPRB` after frequency hopping to the user equipment for both SBFD and non-SBFD time resources, thus allowing SBFD and non-SBFD time resources to use independent parameter values. For PUSCH, current standard discussions support configuring the number of resource blocks (RB) for frequency domain offset between two hops to the user equipment for both SBFD and non-SBFD time resources. offset Therefore, SBFD time resources and non-SBFD time resources adopt independent RBs. offset Value. For frequency hopping between PUSCH slots in SBFD time resources, when PUSCH DMRS binding is not enabled, or the PUSCH is scheduled in DCI format 0_0 with uplink grant carried by RAR or CRC scrambled by TC-RNTI, in SBFD slots The starting resource block for PUSCH is shown in formula (2).
[0064]
[0065] In formula (2), RB UL SB start It is the starting resource block index of the available resource block in the previous row, with reference to the start of the previous row's BWP activation. It is the number of available resource blocks on the uplink, RB start The starting resource block index (RB) of the first hop of the PUSCH is referenced to the start of the upstream BWP activation in the SBFD time resource. offset This refers to the number of resource blocks with frequency domain offset between the two hops used in SBFD time resource allocation. For PUSCH transmissions across SBFD and non-SBFD symbols, RB... start To obtain the frequency domain position of the starting resource block in the first hop of the PUSCH in the SBFD symbol transmission after frequency domain offset, the starting resource block at this position is the resource block index with reference to the start of the upstream active BWP.
[0066] The inventors noted that, for base station-side SBFD within a TDD carrier, if the scheme discussed in the current standard is directly applied, it will lead to the problem that the number of consecutive time slots transmitted by PUSCH and PUCCH using the same frequency domain resources has multiple possible values, which increases the complexity of multi-time slot joint channel estimation and makes it difficult to achieve the purpose of multi-time slot joint channel estimation.
[0067] Specifically, for PUSCH, after applying the scheme discussed in the current standard, that is, combining formulas (2) and (1), in the SBFD time slot... The starting resource block for PUSCH is:
[0068]
[0069] It should be noted that in non-SBFD time slots The starting resource block for PUSCH is shown in formula (1) above.
[0070] For example, such as Figure 3 As shown, time slots 4–7, 8–11, 12–15, and 16–19 are located in different frequency hopping intervals. Within the same frequency hopping interval, the frequency domain resources of PUSCH appear in different positions. The number of consecutive time slots for PUSCH transmission in the same frequency domain resource can be 1, 2, or 3, which increases the complexity of joint channel estimation for consecutive time slots of PUSCH transmission in the same frequency domain resource.
[0071] It should be noted that, in Figure 3 In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, and reference numeral 31 is used to indicate the RB. UL SB start Reference numeral 32 is used to indicate RB for the SBFD symbol. start Reference numeral 33 is used to indicate the symbol used for SBFD. Reference numeral 34 is used to indicate RB for non-SBFD symbols. start Reference numeral 35 is used to indicate the use of non-SBFD symbols.
[0072] For PUCCH, when DMRS binding is enabled, the scheme discussed in the current standard is applied, i.e., SBFD time resources and non-SBFD time resources use independent starting resource block index parameters before frequency hopping (startingPRB) and after frequency hopping (secondHopPRB). For example, Figure 4 As shown, the frequency domain resources of PUCCH appear in different positions within the same frequency hopping interval. The number of consecutive time slots of PUCCH transmission in the same frequency domain resources is 1, 2, or 3, which increases the complexity of joint channel estimation for consecutive time slots of PUCCH transmission in the same frequency domain resources.
[0073] It should be noted that, in Figure 4In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, reference numeral 41 is used to indicate the starting PRB for SBFD symbols, reference numeral 42 is used to indicate the second Hop PRB for SBFD symbols, reference numeral 43 is used to indicate the starting PRB for non-SBFD symbols, and reference numeral 44 is used to indicate the second Hop PRB for non-SBFD symbols.
[0074] Accordingly, this disclosure proposes an uplink frequency hopping method for SBFD. For PUSCH or PUCCH frequency hopping with frequency hopping intervals, it can reduce the possible number of consecutive time slots transmitted using the same frequency domain resources, thereby reducing the complexity of multi-time slot joint channel estimation, which is conducive to realizing multi-time slot joint channel estimation, improving the performance of joint channel estimation, and thus improving uplink coverage.
[0075] Figure 5 This is a flowchart illustrating an uplink frequency hopping method according to an embodiment of the present disclosure. In some embodiments, the following uplink frequency hopping method is performed by the user equipment (UE), including steps 51-52.
[0076] In step 51, the frequency hopping interval configuration information sent by the network device is received.
[0077] In step 52, uplink frequency hopping transmission is performed based on the frequency hopping interval configuration information, wherein the time resources used for uplink frequency hopping transmission include full-duplex time resources.
[0078] In some embodiments, uplink frequency hopping transmission includes uplink frequency hopping transmission using PUSCH or PUCCH.
[0079] In some embodiments, full-duplex time resources include SBFD time resources. For example, time resources include one or more of subframes, time slots, and symbols.
[0080] In some embodiments, the user equipment supports simultaneous uplink transmission in the uplink subband and downlink reception in the downlink subband, i.e., it supports full-duplex.
[0081] In some embodiments, the user equipment only supports uplink transmission in the uplink subband or downlink reception in the downlink subband at any given time, that is, it does not support simultaneous uplink and downlink transmission, and is a half-duplex user equipment.
[0082] It should be noted that the uplink frequency hopping method provided in this disclosure is applicable to PUSCH and PUCCH frequency hopping using frequency hopping intervals. For example, when the base station configures PUSCH DMRS binding enabled to the user equipment and the PUSCH is not scheduled in DCI format 0_0 with CRC scrambling by RAR-bearing uplink grant or TC-RNTI, frequency hopping is performed using the PUSCH frequency hopping interval configured by the base station to the user equipment. When the base station configures PUCCH DMRS binding enabled to the user equipment, frequency hopping is performed using the PUCCH frequency hopping interval configured by the base station to the user equipment.
[0083] Scenario 1: Frequency hopping interval configuration information is used to configure the first frequency hopping interval.
[0084] In Scenario 1, the number of time slots included in the first frequency hopping interval is used to count the available time slots for uplink transmission.
[0085] For example, the number of time slots included in the PUSCH frequency hopping interval is counted only for uplink transmission available time slots. The number of time slots included in the PUCCH frequency hopping interval is counted only for uplink transmission available time slots.
[0086] In some embodiments, downlink time slots that do not contain SBFD symbols and time slots containing SSB (Synchronization Signal / PBCH Block) are not uplink transmission available time slots. That is, uplink transmission available time slots include time slots containing SBFD symbols, time slots containing uplink symbols, and time slots containing flexible symbols other than the time slot containing the SSB.
[0087] In some embodiments, downlink time slots that do not contain SBFD symbols are not uplink transmission available time slots. That is, uplink transmission available time slots include time slots containing SBFD symbols, time slots containing uplink symbols, and time slots containing flexible symbols.
[0088] For PUSCH, when frequency hopping is performed using formula (1) for non-SBFD symbols and formula (3) for SBFD symbols, Replaced with This refers to the sequence number of the currently available uplink transmission time slot within the system radio frame. Numbering the available uplink transmission time slots within the system radio frame yields different... value.
[0089] For example, a PUSCH frequency hopping example when DMRS binding is enabled is as follows: Figure 6 As shown, and Figure 3 In comparison, this reduces the number of consecutive time slots that can be transmitted using the same frequency domain resources.
[0090] It should be noted that, in Figure 6 In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, and reference numeral 61 is used to indicate the RBUL. SBstart Reference numeral 62 is used to indicate RB for the SBFD symbol. start Reference numeral 63 is used to indicate the symbol used for SBFD. Reference numeral 64 is used to indicate RB for non-SBFD symbols. start Reference numeral 65 is used to indicate the use of non-SBFD symbols.
[0091] In existing NR standards, the number of time slots included in the PUSCH frequency hopping interval configured by the base station for the user equipment can be selected as 2, 4, 5, 6, 8, 10, 12, 14, or 16, while the time position period of the SBFD subband is usually a multiple of 5 time slots. Figure 6 The above embodiment has 5 time slots. Using this embodiment, it is advantageous for the base station to select the number of time slots included in the configured PUSCH frequency hopping interval, which is the number of uplink transmission available time slots within the time position period of the SBFD subband. Figure 6 The number of consecutive time slots (which is 4 time slots) is a factor or multiple of the number of time slots, thereby reducing the possibility of using the same frequency domain resources for transmission. This is beneficial for the realization of multi-time slot joint channel estimation and improves PUSCH coverage.
[0092] For PUCCH, starting from the first slot of the repeated PUCCH transmission, every... One consecutive uplink transmission can be achieved by frequency hopping in one time slot. It is the number of time slots included in the PUCCH frequency hopping interval configured by the base station for the user equipment.
[0093] For example, a schematic diagram of PUCCH frequency hopping when DMRS binding is enabled is shown below. Figure 7 As shown, and Figure 4 In comparison, it reduces the possible number of consecutive time slots transmitted using the same frequency domain resources, which is beneficial for the realization of multi-time slot joint channel estimation and improves PUCCH coverage.
[0094] It should be noted that, in Figure 7In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, reference numeral 71 is used to indicate the starting PRB for SBFD symbols, reference numeral 72 is used to indicate the second Hop PRB for SBFD symbols, reference numeral 73 is used to indicate the starting PRB for non-SBFD symbols, and reference numeral 74 is used to indicate the second Hop PRB for non-SBFD symbols.
[0095] In Embodiment 2 of Scenario 1, the number of time slots included in the first frequency hopping interval has an approximate or multiple relationship with the number of related time slots. The number of related time slots includes any one of the following: the number of time slots included in the time position period of the SBFD subband, the number of uplink transmission available time slots included in the time position period of the SBFD subband, the number of time slots included in the TDD uplink / downlink pattern period, and the number of uplink transmission available time slots included in the TDD uplink / downlink pattern period.
[0096] It should be noted that the TDD uplink / downlink pattern period is configured by the parameter `dl-UL-TransmissionPeriodicity` in the TDD uplink / downlink common configuration information element (TDD-UL-DL-ConfigCommon) sent by the base station to the user equipment, representing the period of the time domain location of the TDD uplink / downlink time resources. Current NR standards support base stations configuring two sets of TDD uplink / downlink patterns to user equipment, i.e., configuring two TDD uplink / downlink pattern periods. When configuring one TDD uplink / downlink pattern period, the time location period of the SBFD subband is the same as the TDD uplink / downlink pattern period. When configuring two TDD uplink / downlink periods, the time location period of the SBFD subband is the same as the sum of the two TDD uplink / downlink patterns.
[0097] It should also be noted that the approximate or multiple relationship can be that the protocol restricts the user equipment from expecting the number of time slots included in the frequency hopping interval configured by the base station to be an approximation or multiple of the relevant time slot number, or the frequency hopping interval configuration information configured by the base station indicates that the number of time slots included in the frequency hopping interval is an approximation or multiple of the relevant time slot number, or the base station selects the configured frequency hopping interval based on the candidate values of the number of time slots included in the existing frequency hopping interval and the configured relevant time slot number, thereby achieving the approximation or multiple relationship between the number of time slots included in the configured frequency hopping interval and the relevant time slot number (implemented by the base station).
[0098] For example, the frequency hopping interval configuration information is used to configure the first parameter value. The number of time slots included in the first frequency hopping interval is determined by multiplying any one of the following by the first parameter value: the number of time slots included in the time position period of the SBFD subband, the number of uplink transmission available time slots included in the time position period of the SBFD subband, the number of time slots included in the TDD uplink / downlink pattern period, and the number of uplink transmission available time slots included in the TDD uplink / downlink pattern period. For example, if the frequency hopping interval configuration information configures the first parameter value to 0.5, and the number of uplink transmission available time slots included in the TDD uplink / downlink pattern period is 4, then the number of time slots included in the first frequency hopping interval is 2.
[0099] In this embodiment, the number of time slots included in the first frequency hopping interval configured by the base station for the user equipment has an approximate or multiple relationship with one of the number of uplink transmission available time slots included in the time position period of the SBFD subband and the number of uplink transmission available time slots included in the TDD uplink and downlink pattern period, which is applied in conjunction with Embodiment 1.
[0100] For example, this scheme can be applied to PUSCH frequency hopping using frequency hopping intervals. For instance, the PUSCH frequency hopping interval configured by the base station for the user equipment is a multiple of the number of uplink transmission available time slots contained in the time position period of the SBFD subband. Figure 3 In the example, the uplink transmission available time slots included in the time position period of the SBFD subband are 4. If the PUSCH frequency hopping interval is configured as 8, the PUSCH frequency hopping diagram is as follows. Figure 8 As shown.
[0101] It should be noted that, in Figure 8 In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, and reference numeral 81 is used to indicate the RB. UL SB start Reference numeral 82 is used to indicate RB for the SBFD symbol. start Reference numeral 83 is used to indicate the symbol used for SBFD. Reference numeral 84 is used to indicate RB for non-SBFD symbols. start Reference numeral 85 is used to indicate the use of non-SBFD symbols.
[0102] Scenario 2: Frequency hopping interval configuration information is used to configure the second frequency hopping interval and the third frequency hopping interval. The second frequency hopping interval is applied to the first time resource set for uplink transmission by the user equipment, and the third frequency hopping interval is applied to the second time resource set for uplink transmission by the user equipment.
[0103] In some embodiments, the first time resource set includes time resources within a plurality of first TDD uplink / downlink pattern periods, and the second time resource set includes time resources within a plurality of second TDD uplink / downlink pattern periods.
[0104] For example, this embodiment can be applied to PUSCH frequency hopping using frequency hopping intervals. The base station configures PUSCH frequency hopping interval 1 (i.e., the second frequency hopping interval) and PUSCH frequency hopping interval 2 (i.e., the third frequency hopping interval) to the user equipment. PUSCH frequency hopping interval 1 is applied to the period configured by the parameter dl-UL-TransmissionPeriodicity in the information element of pattern 1 configured by the base station to the user equipment, that is, to the uplink and downlink time slot period configured in pattern 1. PUSCH frequency hopping interval 2 is applied to the period configured by the parameter dl-UL-TransmissionPeriodicity in the information element of pattern 2 configured by the base station to the user equipment, that is, to the uplink and downlink time slot period configured in pattern 2.
[0105] It should be noted that the number of time slots included in each configured frequency hopping interval has an approximate or multiple relationship with one of the following: the number of time slots included in the applied TDD uplink / downlink pattern period, or the number of uplink available time slots included in the applied TDD uplink / downlink pattern period. This approximate or multiple relationship can be achieved by: the protocol requiring user equipment not to expect the number of time slots included in the frequency hopping interval configured by the base station to be an approximation or multiple of the number of time slots included in its applied TDD uplink / downlink pattern period or the number of uplink available time slots; or by the base station selecting the first and second configured frequency hopping intervals based on candidate values of the number of time slots included in the existing frequency hopping intervals and the number of time slots included in the configured TDD uplink / downlink pattern period or the number of uplink available time slots (implemented by the base station).
[0106] In Scenario 2, the number of time slots included in the second frequency hopping interval is used to count the time slots within each of the multiple first TDD uplink / downlink pattern cycles, and the number of time slots included in the third frequency hopping interval is used to count the time slots within each of the multiple second TDD uplink / downlink pattern cycles.
[0107] For example, the first TDD uplink / downlink pattern period is 20ms, and the second TDD uplink / downlink pattern period is 10ms, with the first and second TDD uplink / downlink pattern periods alternating. Therefore, within a 60ms time period, the TDD uplink / downlink pattern periods are arranged as 20ms, 10ms, 20ms, and 10ms cycles. A time slot is 0.5ms, so the first TDD uplink / downlink pattern period includes 40 time slots, and the second TDD uplink / downlink pattern period includes 20 time slots. Within a 60ms time period, the second frequency hopping interval counts all 80 time slots within the two 20ms periods, and the third frequency hopping interval counts all 40 time slots within the two 10ms periods.
[0108] In Scenario 2, the number of time slots included in the second frequency hopping interval is approximately or multiple of the number of time slots included in the first TDD uplink / downlink pattern cycle, and the number of time slots included in the third frequency hopping interval is approximately or multiple of the number of time slots included in the second TDD uplink / downlink pattern cycle.
[0109] For example, the frequency hopping interval configuration information is used to configure the second and third parameter values. The number of time slots included in the second frequency hopping interval is determined based on the product of the number of time slots included in the first TDD uplink / downlink pattern cycle and the second parameter value. The number of time slots included in the third frequency hopping interval is determined based on the product of the number of time slots included in the second TDD uplink / downlink pattern cycle and the third parameter value.
[0110] It should be noted that, for PUSCH, when frequency hopping of non-SBFD symbols is performed using the above formula (1) and when frequency hopping of SBFD symbols is performed using the above formula (3), Replace with or This refers to the sequence number of the current time slot within the TDD uplink / downlink pattern period applied during frequency hopping interval 1 within the system radio frame. Numbering the time slots within the TDD uplink / downlink pattern period applied during frequency hopping interval 1 within the system radio frame yields different... value. This is the sequence number of the current time slot within the TDD uplink / downlink pattern period applied during frequency hopping interval 2 within the system's radio frame. Numbering the time slots within the TDD uplink / downlink pattern period applied during frequency hopping interval 2 within the system's radio frame yields different... value.
[0111] In Scenario 2, Embodiment 3, the number of time slots included in the second frequency hopping interval is used to count the available uplink transmission time slots within each of the plurality of first TDD uplink / downlink pattern periods. The number of time slots included in the third frequency hopping interval is used to count the available uplink transmission time slots within each of the plurality of second TDD uplink / downlink pattern periods.
[0112] In Scenario 2, Example 4, the number of time slots included in the second frequency hopping interval is approximately or a multiple of the number of available uplink transmission time slots included in the first TDD uplink / downlink pattern cycle. The number of time slots included in the third frequency hopping interval is approximately or a multiple of the number of available uplink transmission time slots included in the second TDD uplink / downlink pattern cycle.
[0113] For example, the frequency hopping interval configuration information is used to configure the fourth and fifth parameter values. The number of time slots included in the second frequency hopping interval is determined based on the product of the number of available uplink transmission time slots included in the first TDD uplink / downlink pattern cycle and the fourth parameter value. The number of time slots included in the third frequency hopping interval is determined based on the product of the number of available uplink transmission time slots included in the second TDD uplink / downlink pattern cycle and the fifth parameter value.
[0114] It should be noted that, for PUSCH, when frequency hopping of non-SBFD symbols is performed using the above formula (1) and when frequency hopping of SBFD symbols is performed using the above formula (3), Replace with or This refers to the sequence number of the currently available uplink transmission time slot within the TDD uplink / downlink pattern period applied during frequency hopping interval 1 within the system radio frame. Numbering the available uplink transmission time slots within the TDD uplink / downlink pattern period applied during frequency hopping interval 1 within the system radio frame yields different... value. This refers to the sequence number of the currently available uplink transmission time slot within the TDD uplink / downlink pattern period applied during frequency hopping interval 2 within the system's radio frame. Numbering the available uplink transmission time slots within the TDD uplink / downlink pattern period applied during frequency hopping interval 2 within the system's radio frame yields different... value.
[0115] For example, a schematic diagram of PUSCH frequency hopping when DMRS binding is enabled is shown below. Figure 9 As shown, Figure 9 The PUSCH frequency hopping interval is configured as 4 for TDD uplink and downlink pattern cycles with 3 SBFD time slots and 1 uplink time slot, and as 2 for TDD uplink and downlink pattern cycles with 2 SBFD time slots and 2 uplink time slots.
[0116] It should be noted that, in Figure 9 In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, and reference numeral 91 is used to indicate the RB. UL SB start Reference numeral 92 is used to indicate RB for the SBFD symbol. start Reference numeral 93 is used to indicate the symbol used for SBFD. Reference numeral 94 is used to indicate RB for non-SBFD symbols. start Reference numeral 95 is used to indicate the use of non-SBFD symbols.
[0117] In some embodiments, the first time resource set includes SBFD time slots, and the second time resource set includes non-SBFD time slots.
[0118] In the fifth embodiment of Scenario 2, the number of time slots included in the second frequency hopping interval is used to count the SBFD time slots, and the number of time slots included in the third frequency hopping interval is used to count the uplink transmission available time slots in the non-SBFD time slots.
[0119] In the sixth embodiment of Scenario 2, the number of time slots included in the second frequency hopping interval is approximately or a multiple of the number of SBFD time slots included in the TDD uplink / downlink pattern period. The number of time slots included in the third frequency hopping interval is approximately or a multiple of the number of uplink transmission available time slots among the non-SBFD time slots included in the TDD uplink / downlink pattern period.
[0120] For example, the frequency hopping interval configuration information is used to configure the sixth and seventh parameter values. The number of time slots included in the second frequency hopping interval is determined based on the product of the number of SBFD time slots included in the TDD uplink / downlink pattern period and the sixth parameter value. The number of time slots included in the third frequency hopping interval is determined based on the product of the number of uplink transmission available time slots in the non-SBFD time slots included in the TDD uplink / downlink pattern period and the seventh parameter value.
[0121] It should be noted that the approximation or multiple relationship can be that the user equipment does not expect the number of time slots included in the second frequency hopping interval configured by the base station to be an approximation or multiple of the number of SBFD time slots included in the TDD uplink / downlink pattern period, and the user equipment does not expect the number of time slots included in the third frequency hopping interval configured by the base station to be an approximation or multiple of the number of uplink transmission available time slots in the non-SBFD time slots included in the TDD uplink / downlink pattern period. Alternatively, the frequency hopping interval configuration information configured by the base station may represent this approximation or multiple, or the base station may select the configured first and second frequency hopping intervals based on the candidate values of the number of time slots included in the existing frequency hopping intervals to achieve this approximation or multiple relationship (implemented by the base station).
[0122] For example, this embodiment can be applied to PUSCH frequency hopping using frequency hopping intervals. For instance, the base station configures PUSCH frequency hopping interval 3 (i.e., the second frequency hopping interval) and PUSCH frequency hopping interval 4 (i.e., the third frequency hopping interval) to the user equipment. PUSCH frequency hopping interval 3 is applied to SBFD time slots, and PUSCH frequency hopping interval 4 is applied to non-SBFD time slots.
[0123] For example, for PUSCH, when frequency hopping of non-SBFD symbols is performed using the above formula (1), Replace with When the frequency hopping of the SBFD symbol adopts the above formula (3), Replace with This refers to the sequence number of the currently available uplink transmission time slot within the non-SBFD time slots of the system radio frame. Numbering the available uplink transmission time slots within the non-SBFD time slots of the system radio frame yields different... value. This is the sequence number of the current SBFD time slot within the system radio frame. Numbering the SBFD time slots within the system radio frame yields different... value.
[0124] For example, a schematic diagram of PUSCH frequency hopping when DMRS binding is enabled is shown below. Figure 10 As shown, Figure 10 The PUSCH frequency hopping interval for SBFD time slots is configured as 6, and the PUSCH frequency hopping interval for non-SBFD time slots is configured as 2.
[0125] It should be noted that, in Figure 10 In the figure, reference numeral 1001 is used to indicate the uplink subband, reference numeral 1002 is used to indicate the uplink active BWP, reference numeral 1003 is used to indicate the uplink available PRB, and reference numeral 101 is used to indicate the RB. UL SB start Reference numeral 102 is used to indicate RB for SBFD notation. start Reference numeral 103 is used to indicate the symbol used for SBFD. Reference numeral 104 is used to indicate RB for non-SBFD symbols. start Reference numeral 105 is used to indicate the use of non-SBFD symbols.
[0126] In the uplink frequency hopping method provided in the above embodiments of this disclosure, for PUSCH or PUCCH frequency hopping with frequency hopping intervals, the possible number of consecutive time slots transmitted using the same frequency domain resources can be reduced, thereby reducing the complexity of multi-time slot joint channel estimation, which is beneficial to realizing multi-time slot joint channel estimation, improving the performance of multi-time slot joint channel estimation, and improving uplink coverage.
