[0223] To improve UL coverage and throughput, subband full duplex (SBFD) will be studied in the duplex enhancement project in Rel-18. Specifically, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain in downlink (DL) or flexible (F) symbols, the multiple SBs including UL subbands (UL SBs) for uplink (UL) transmission and DL subbands (DL SBs) for downlink (DL) transmission, such as one UL subband (UL SB) and at least one (such as 1 or 2) DL subband (DL SB), the base station can transmit DL signals in the DL subbands and receive UL signals in the UL subbands at the same time. Optionally, the DL symbols are symbols configured as DL by TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated or symbols indicated as DL by DCI format 2-0. Optionally, the F symbols are symbols configured as F by TDD-UL-DL-ConfigCommon or TDD-UL-DL-ConfigDedicated or symbols indicated as F by DCI format 2-0. When a symbol contains both a DL subband and a UL subband in the frequency domain, the symbol can be referred to as an SBFD symbol. Similarly, when a slot contains multiple symbols, including at least one SBFD symbol, the slot can be referred to as an SBFD slot. Referring to FIG. 1B, slot #0 is a DL slot containing 14 DL symbols, slots #1-3 are SBFD slots, each containing 14 SBFD symbols, each SBFD symbol containing one UL subband and two DL subbands, and slot #4 is a UL slot containing 14 UL symbols.

[0224] Between the DL subbands and the UL subbands, there can be a guard band (GB), and frequency domain isolation through the guard band can reduce interference between the DL signals in the DL subbands and the UL signals in the UL subbands.

[0225] In the SBFD symbol, the GB and DL subbands are not available for UL transmission, and the UL subbands are available for UL transmission. In the SBFD symbol, the frequency domain range available for UL transmission can be referred to as an UL available frequency domain range, and the frequency domain range unavailable for UL transmission can be referred to as an UL unavailable frequency domain range. According to the above analysis, the UL frequency domain range of the non-SBFD (non-SBFD) symbol and the SBFD symbol is different. The above-mentioned UL available frequency domain range is the UL frequency domain range on the CC. In the SBFD symbol, the UL available frequency domain range on the UL BWP (UL BandWidth Part, uplink bandwidth part) refers to the frequency domain range overlapping the UL available frequency domain range on the CC. Unless otherwise specified, the UL available frequency domain range in the following refers to the UL available frequency domain range on the UL BWP.

[0226] When the UE is in an idle state, the UE measures the received signal strength and other information of the synchronization signal block (SS / PBCH block, SSB) beam when initially accessing a cell, and selects the optimal SSB beam. In the direction of the optimal SSB beam, a PRACH signal is sent in an RO (RACH Occasion, random access channel occasion) to perform random access. In addition, in other states, the UE can also send a PRACH signal in an RO to perform random access. Random access includes CBRA (Contention-Based Random Access, contention-based random access) and CFRA (Contention-Free Random Access, non-contention-based random access), wherein in CBRA, there is a case where multiple UEs use the same random access preamble (preamble sequence), that is, the PRACH signals of multiple UEs collide, which can cause random access to fail.

[0227] The UE can send an uplink signal in the UL subband of the SBFD symbol. In the process of random access, after receiving Msg4 or MsgB, the UE needs to send HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement, Hybrid Automatic Repeat Request-Acknowledgement) information on the PUCCH. After the base station successfully receives the HARQ-ACK, it indicates that the random access is successful. Therefore, the UE can transmit the HARQ-ACK information in the SBFD symbol, which can send the HARQ-ACK information in advance and reduce the random access delay compared with transmitting the HARQ-ACK information only in the UL or F symbol. FIG. 1C is a schematic diagram of PUCCH in the SBFD symbol.

[0228] Considering the different UL available frequency ranges on SBFD symbols and non-SBFD symbols, according to the related art, it can cause PUCCH resource outside the UL sub-band on SBFD symbols, resulting in PUCCH resource being unavailable.

[0229] For ease of understanding, the related art in PUCCH is introduced as follows.

[0230] When the UE is configured with PUCCH resource by pucch-ResourceCommon and the UE is not configured with useInterlacePUCCH-PUSCH, the frequency domain range of PUCCH is determined according to the parameters pucch-ResourceCommon and other information. The specific determination manner can refer to the following manner:

[0231] When:

[0232] The index of the starting PRB of the first hop of PUCCH is

[0233] The index of the starting PRB of the second hop of PUCCH is

[0234] When:

[0235] The index of the starting PRB of the first hop of PUCCH is

[0236] The index of the starting PRB of the second hop of PUCCH is

[0237] In the above formula, r PUCCH is the index of PUCCH resource (PUCCH resource index), which can be determined according to the high layer configuration pucch-ResourceCommon and other parameters.

[0238] According to the above embodiment, When, the starting PRB of the first hop of PUCCH is The starting PRB of the second hop of PUCCH is When, the starting PRB of the first hop of PUCCH is The starting PRB of the second hop of PUCCH is

[0239] r' PUCCH is r PUCCH or r PUCCH -8.

[0240] r' PUCCH r PUCCH ; r' PUCCH r PUCCH -8.

[0241] An example of PUCCH frequency hopping is shown in FIG. 1D, assuming N RB = 1, the starting RB of the first hop and the second hop of PUCCH are determined according to and . The left diagram in FIG. 1D represents the case that the symbol where PUCCH locates is non-SBFD symbol, and the right diagram represents the case that the symbol where PUCCH locates is SBFD symbol. It can be seen that if the frequency range of PUCCH on SBFD symbol is determined in the way of non-SBFD symbol, since the starting frequency domain position of PUCCH on SBFD symbol does not consider the frequency range of UL transmission on SBFD symbol, the PUCCH resource on SBFD symbol is out of the UL subband (on the DL subband), and the PUCCH resource cannot be used.

[0242] When the UE is configured with PUCCH resource by pucch-ResourceCommon, and the UE is configured with useInterlacePUCCH-PUSCH, the frequency range of PUCCH is determined according to the Interlace index of PUCCH resource and the RBs contained in Interlace in UL BWP.

[0243] FIG. 1E is an example of CRBs contained in Interlace according to the existing protocol. The CRBs are divided into M Interlaces (M is the number of Interlaces), and the CRBs contained in each Interlace in BWP #i can be understood as the intersection of BWP #i and Interlace. In the example of FIG. 1E, the CRBs contain CRB #0-79, which are divided into 5 Interlaces, and BWP contains CRB #4-72. Therefore, the CRBs contained in each Interlace in BWP are:

[0244] Interlace #0: 5, 10, 15, 20, …, 70;

[0245] Interlace #1: 6, 11, 16, 21, …, 71;

[0246] Interlace #2: 7, 12, 17, 22, …, 72;

[0247] Interlace#3: 8, 13, 18, 23, …, 68;

[0248] Interlace#4: 4, 9, 14, 19, 24, …, 69.

[0249] For example, according to the Interlace index m of the PUCCH resource, assuming m is 2, and the set of CRBs contained by Interlace#2 within the UL BWP, the set of RBs contained by the PUCCH, i.e., the frequency domain range of the PUCCH, is determined.

[0250] In the above embodiment, the following problems may exist:

[0251] If the UE is not configured useInterlacePUCCH-PUSCH, the starting frequency domain position of the PUCCH on the SBFD symbol does not consider the frequency domain range of the UL transmission on the SBFD symbol, resulting in that the PUCCH on the SBFD symbol cannot be used on the DL subband; the PUCCH can hop within a slot, and the frequency hopping offset is currently determined according to the UL BWP, which may cause the second hop (2 nd hop) to be outside the UL subband, and cannot be used;

[0252] If the UE is configured useInterlacePUCCH-PUSCH, if the RBs contained by the Interlace are determined according to the non-SBFD symbol, the Interlace may contain RBs outside the UL subband, resulting in that the PUCCH cannot be used.

[0253] Therefore, the embodiments of the present disclosure need to consider how to determine the frequency domain range of the PUCCH on the SBFD symbol.

[0254] FIG. 2A is an interaction schematic diagram of a communication method according to an embodiment of the present disclosure. In some embodiments, the embodiment of FIG. 2A can be used in a scenario in which the terminal is not configured useInterlacePUCCH-PUSCH, but is not limited thereto.

[0298] On the SBFD symbol, the UL subband can be used for UL transmission. If the PUCCH is in the UL subband, it can be used to send the PUCCH signal, otherwise, the PUCCH cannot be used to send the PUCCH signal. In one example, on the SBFD symbol, if the frequency domain range of the PUCCH signal is understood according to the non-SBFD symbol, the starting RB of the first hop (1 st hop) of the PUCCH (i.e. the offset between the starting RB and the first RB of the UL BWP) is the starting RB of the second hop (2 nd hop) is Referring to FIG. 1D, assuming that N RB =1, the first hop and the second hop of the PUCCH are outside the UL subband, resulting in that the PUCCH cannot be used.

[0299] To avoid the above problem, in some embodiments, the starting RB of the first hop of the PUCCH can be determined according to the following scheme:

[0300] In one example, the value of C is C1, and the value of N RB is 1.

[0301] The starting RB of the first hop of the PUCCH on the SBFD symbol is denotes the offset of the starting RB of the first hop of the PUCCH relative to the starting RB of the UL subband, and C1 is by selecting a proper r' PUCCH and N CS , the starting RB of the first hop of the PUCCH can be ensured to be within the UL subband. Referring to FIG. 2C, the first hop and the second hop of the PUCCH are within the UL subband.

[0302] In one example, the value of C is C2, and the value of N RB is 1.

[0303] The starting RB of the first hop of the PUCCH on the SBFD symbol is denotes the offset of the starting RB of the first hop of the PUCCH relative to the starting RB of the UL subband, and C2 is or or round(C1 / A), assuming that the value of A is 2 as agreed by the protocol, configured by higher layer, or determined according to parameters, the value of C1 can be prevented from being too large, causing the first hop of the PUCCH on the SBFD symbol to be outside the UL subband, and further causing the PUCCH on the SBFD symbol to be unavailable.

[0304] In one example, the value of C is C3, and the value of N RB is 1.

[0305] The starting RB of the first hop of the PUCCH on the SBFD symbol is denotes the offset of the starting RB of the first hop of the PUCCH relative to the starting RB of the UL subband, and C3 is C1 mod B, assuming that the value of B is , the value of C1 mod B can be ensured to be less than , so that the starting RB of the first hop of the PUCCH can be ensured to be within the UL subband.

[0306] Assuming that the value of B is , the value of C1 mod B can be ensured to be less than , so that the starting RB of the first hop of the PUCCH can be ensured to be within the UL subband.

[0307] In some embodiments, the starting RB of the first hop of the PUCCH can also be determined according to the following scheme:

[0308] In one example, D is equal to C1, N RB is equal to 1.

[0309] On the SBFD symbol, the offset of the starting RB of the first hop of PUCCH relative to the starting RB of the UL BWP is C1, by selecting appropriate r' PUCCH and N CS , it can be guaranteed that the first hop of PUCCH is within the UL subband.

[0310] Therefore, according to the above embodiment, the starting RB of the first hop or the second hop of PUCCH is which can guarantee that the first hop or the second hop is within the UL subband.

[0311] In some embodiments, satisfy one of the following formulas:

[0312] wherein, is the largest PRB index (ending PRB index) in the UL subband plus 1, is the largest PRB index in the UL BWP plus 1 or the number of PRBs contained in the UL BWP, N RB is the number of PRBs contained in the PUCCH.

[0313] and may be the same or different.
