[0023] In some embodiments, the terminal in the embodiments of the present application may be a Device with Reduced Capability (RedCap), which can support a bandwidth of 5 MHz, and the 5 MHz bandwidth is only applicable to the RedCap Baseband Band Width (BBBW) or Radio Frequency Band Width (RFBW). Also, the above 5 MHz bandwidth can be a continuous or discrete 5 MHz bandwidth.

[0024] In some embodiments, for RedCap, both the radio frequency bandwidth and the baseband bandwidth are 5 MHz for both the uplink and the downlink.

[0028] Also, in some embodiments, for a data channel, the 5 MHz bandwidth may be understood as the number / size of the frequency domain resource occupied by the data channel being 5 MHz or less.

[0029] Hereinafter, with reference to the drawings, a frequency domain resource determination method, a terminal, and a network-side device provided by the embodiments of the present application will be described in detail by way of several examples and their application scenarios.

[0030] Referring to FIG. 2 which is a flowchart of the frequency domain resource determination method provided by the embodiments of the present application, as shown in FIG. 2, the method includes the following steps 201 to 202.

[0031] In step 201, the terminal determines the related information of the control channel, and the related information of the control channel includes at least one of the first frequency domain resource allocation range of the control channel, the time domain parameter of the control channel, and the scheduling information of the control channel.

[0032] The above related information of the control channel may be set by the network side for the terminal, may be determined by the terminal based on pre-established rules, or may be defined by a protocol, etc., and is not limited here. Also, for the terminal to determine the related information of the control channel, it may be determined by the terminal before receiving the above control channel, may be determined when detecting the above control information, or may be determined after receiving the above control channel.

[0033] The above first frequency domain resource allocation range may be the bandwidth of the first frequency domain resource allocation range or the specific position of the frequency domain, for example, the frequency domain resource allocation of control information. The time domain parameters of the above control channel may be the time domain resource allocation of the above control channel, for example, the time domain position or the time interval associated with the above control channel. The scheduling information of the above control channel may be the information scheduled by the above control information, or may be the capability information of the terminal related to the scheduling of the above control channel.

[0034] In step 202, the terminal determines the bandwidth of the second frequency domain resource allocation range based on the relevant information. The second frequency domain resource allocation range is the frequency domain resource allocation range of the transmission target. The transmission target is the object transmitted and received by the terminal based on the received control channel. The transmission target includes at least one of a channel and a signal. Here, the bandwidth of the second frequency domain resource allocation range is 5 MHz or less, or the bandwidth of the second frequency domain resource allocation range is 20 MHz or less.

[0035] The above transmission target may be a channel such as a data channel, or may be a signal such as a reference signal.

[0036] In some embodiments, the above transmission target may be the object scheduled by the above control information. The object transmitted and received by the terminal based on the received control channel may be understood as the object that the terminal transmits and receives based on the scheduling by the control information, for example, the channel or signal that the terminal transmits and receives based on the scheduling by the control information.

[0037] In some embodiments, the transmission target may be a transmission target triggered by the control information, and the object transmitted and received by the terminal based on the received control channel may be understood as an object that triggers transmission and reception based on the control information received by the terminal, for example, a channel or signal by which the terminal triggers transmission and reception based on the control information.

[0038] The terminal determining the bandwidth of the second frequency region resource allocation range based on the related information as described above may be the terminal determining the bandwidth of the second frequency region resource allocation range to be 5 MHz or less, or 20 MHz or less based on the related information.

[0039] In the embodiments of the present application, by the above steps, the bandwidth of the second frequency region resource allocation range can be determined based on the related information of the control channel. In this way, compared with the prior art where the bandwidth of the frequency region resource allocation range is fixed, the embodiments of the present application can improve the flexibility of frequency region resource allocation. Also, in order to improve the flexibility of scheduling by the network side, the network side can schedule the terminal to perform transmission within the above-mentioned second frequency region resource allocation range.

[0040] In the embodiments of the present application, through the above steps, in some cases, it is possible to achieve that the bandwidth of the second frequency domain resource allocation range is 5 MHz or less. Therefore, communication of RedCap terminals with a maximum bandwidth of 5 MHz is supported, and the complexity of storage in the terminal can be reduced. In some cases, when the second frequency domain resource allocation range is 20 MHz or less, the flexibility of network scheduling can be guaranteed. Also, since the frequency domain range for receiving a data channel or a reference signal can exceed 5 MHz, the terminal can buffer some unnecessary signals or data until the PDCCH to be scheduled is requested and the PRB where the data or reference signal to be scheduled is located is determined. Further, when the second frequency domain resource allocation range is 20 MHz or less, communication of non-RedCap terminals can be supported, and coexistence of RedCap terminals and non-RedCap terminals can be realized.

[0041] As an alternative embodiment, the above method further includes a step in which the terminal transmits the transmission target within the second frequency domain resource allocation range, and a step in which the terminal receives the transmission target within the second frequency domain resource allocation range, and includes at least one of them.

[0042] As an alternative embodiment, the second frequency domain resource allocation range is the frequency domain resource allocation range of the transmission target recognized or desired by the terminal.

[0043] The frequency domain resource allocation range of the transmission target recognized or desired by the above-mentioned terminal may be the bandwidth of the frequency domain resource allocation range of the transmission target recognized or desired by the terminal, that is, the bandwidth is what the terminal recognizes or desires, and the terminal recognizes or desires that the network-side device allocates the frequency domain resources of the transmission target so as not to exceed the bandwidth.

[0044] When the second frequency domain resource allocation range determined by the network side device does not match what the terminal recognizes or desires, the behavior of the terminal may be undefined behavior, or the terminal may recognize that there is an error, or, when they do not match, the terminal still transmits and receives the transmission target within the second frequency domain resource allocation range that the terminal recognizes or desires.

[0045] As an alternative embodiment, when the bandwidth of the first frequency domain resource allocation range is 20 MHz or less, the bandwidth of the second frequency domain resource allocation range is 5 MHz or less, or the bandwidth of the second frequency domain resource allocation range is 20 MHz or less, and / or when the bandwidth of the first frequency domain resource allocation range is 5 MHz or less, the bandwidth of the second frequency domain resource allocation range is 5 MHz or less.

[0046] For example, when the resource allocation range of the control channel in the frequency domain is 20 MHz or less (e.g., more than 5 MHz and less than 20 MHz), the terminal determines that the resource allocation range in the frequency domain of the channel or signal (e.g., data channel or reference signal) scheduled by the control channel is 5 MHz or less, and 20 MHz or less (e.g., more than 5 MHz and less than 20 MHz), and recognizes or desires that it may be at least one of them.

[0047] For example, when the resource allocation range of the control channel in the frequency domain is 5 MHz or less, the terminal does not desire that the resource allocation range in the frequency domain of the channel or signal (e.g., data channel or reference signal) scheduled by the control channel is more than 5 MHz.

[0048] In this embodiment, it is possible to directly determine the bandwidth of the second frequency domain resource allocation range based on the bandwidth of the first frequency domain resource allocation range, thereby reducing the complexity of determining the bandwidth.

[0049] As an optional embodiment, the first frequency region resource allocation range includes the frequency region resource allocation range of a first control resource set (CORESET) associated with the control channel. The first control resource set is a control resource set for scheduling a target system information block (SIB). The bandwidth of the frequency region resource allocation range of the first control resource set is 20 MHz or less. The target SIB includes SIB1. Under a first condition, the second frequency region resource allocation range is equal to the frequency region resource allocation range of the first control resource set, and / or Under a second condition, the bandwidth of the second frequency region resource allocation range is 5 MHz or less, and / or the start position of the second frequency region resource allocation range is the same as the start position of the first control resource set.

[0050] The first control resource set may be CORESET0 defined by the protocol. CORESET0 is a special CORESET for scheduling SIB1. However, it is not limited here. The first control resource set may be a control information resource set for scheduling the target SIB defined by a subsequent protocol. The target SIB may or may not include other SIBs other than SIB1. SIB1 is SIB1 defined by the protocol.

[0051] The first condition is Receiving PDCCH in a first common search space (CSS), The PDCCH received by the terminal is scrambled by a first radio network temporary identifier (RNTI), The terminal is in an idle state or an inactive state, including at least one of: the terminal not reporting to the network side the capability information of the terminal that supports up to 5 MHz.

[0052] Here, the first CSS includes: a CSS for scheduling a target SIB including SIB1, a CSS for scheduling other SIBs that are SIBs other than the target SIB, a CSS for receiving a PDCCH of information 2 (MSG2) in a random access process, a CSS for receiving a PDCCH of information B (MSGB) in a random access process, a CSS for receiving a PDCCH of information 4 (MSG4) in a random access process, a CSS for receiving a PDCCH for paging, a CSS for receiving a PDCCH for paging early identification information, including at least one of them.

[0053] The CSS for scheduling the above-mentioned target SIB may be a Type 0 CSS defined by the protocol, and the CSS for scheduling the above-mentioned other SIBs may be a Type 0A CSS defined by the protocol. The CSS for receiving the PDCCH of information 2 (MSG2) in the above-mentioned random access process may be a Type 1 CSS defined by the protocol, the CSS for receiving the PDCCH of information B (MSGB) in the above-mentioned random access process may be a Type 1 CSS defined by the protocol, and the CSS for receiving the PDCCH of information 4 (MSG4) in the above-mentioned random access process may be a Type 1 CSS defined by the protocol. The CSS for receiving the above-mentioned PDCCH for paging may be a Type 2 CSS defined by the protocol. The CSS for receiving the PDCCH that pages the above-described early identification information may be a Type 2 CSS defined by the protocol.

[0054] It should be noted that the specific type of the above CSS is not limited in the embodiments of the present application. For example, in addition to the above Type 0 CSS, Type 0A CSS, Type 1 CSS, and Type 2 CSS, the above first CSS may be other types of CSS.

[0055] The above first RNTI may include at least one of a System Information RNTI (SI-RNTI), a Paging RNTI (P-RNTI), a Random Access RNTI (RA-RNTI), a Message B MSGB (MSGB-RNTI), and a Temporary Cell-Radio Network Temporary Identifier (TC-RNTI).

[0056] The fact that the above-described terminal has not reported to the network side the capability information of the terminal that supports up to 5 MHz means that when an idle / inactive state terminal starts a random access, depending on the network configuration (a setting that permits or does not permit the terminal to report that type), the terminal may not report to the network the capability to support a bandwidth of up to 5 MHz in MSG1 or MSGA or MSG3.

[0057] The above second condition is that the PDCCH is received with a second CSS, the PDCCH is received in a UE-specific search space (USS), the PDCCH received by the terminal is scrambled by a second RNTI, and the terminal is in a connected state. The terminal has reported to the network side the capability information of the terminal that supports up to 5 MHz, and includes at least one of Here, the second CSS includes a CSS for receiving common downlink control information (DCI) of a set of terminals.

[0058] The CSS for receiving the common downlink control information (DCI) of the above-mentioned set of terminals may be a Type 3 CSS defined by the protocol.

[0059] The second RNTI may include at least one of a cell radio network temporary identifier (Cell RNTI, C-RNTI), a modulation and coding scheme cell radio network temporary identifier (Modulation and Coding Scheme Cell-RNTI, MCS-C-RNTI), and a configured scheduling RNTI (Configured Scheduling RNTI, CS-RNTI).

[0060] As an alternative embodiment, the first frequency region resource allocation range includes the frequency region resource allocation range of a second control resource set associated with the control channel. The second control resource set is not for scheduling the target SIB. The bandwidth of the frequency region resource allocation range of the second control resource set is 20 MHz or less. The target SIB includes SIB1. The bandwidth of the second frequency region resource allocation range is 5 MHz or less, and / or the start position of the second frequency region resource allocation range is the same as the start position of the control resource set or the current active bandwidth part (Bandwidth Part, BWP), and / or Under a third condition, the bandwidth of the second frequency region resource allocation range is 5 MHz or less, or the bandwidth of the second frequency region resource allocation range is 20 MHz or less. The third condition is The slot in which the PDCCH received by the terminal on the control channel is located does not overlap with the slot in which the transmission target is located.

[0061] The second control resource set may be a control resource set other than those for scheduling the target SIB, such as CORESET i where i≠0.

[0062] The PDCCH received by the terminal on the control channel as described above may be such that the control channel received by the terminal includes the PDCCH. For example, the control channel is a PDCCH.

[0063] In one embodiment, it is as follows.

[0064] When 5 MHz ≤ CORESET0 ≤ 20 MHz, when the terminal detects a PDCCH for scheduling data in CORESET0, the following terminal behaviors 1 to 4 may occur to the terminal.

[0065] In terminal behavior 1, the terminal recognizes that the frequency domain resource range scheduled / assigned to the data is the same as the frequency domain resource range where CORESET0 is located, or In terminal behavior 2, the terminal does not desire that the frequency domain resource range scheduled / assigned to the data exceeds 5 MHz, and the start position of the 5 MHz is the same as the start position of CORESET0, or In terminal behavior 3, the detected PDCCH is at least Type0 CSS, or Type0 / 0A / 1 / 2 CSS, or is scrambled by SI-RNTI, or is a PDCCH scrambled by SI-RNTI / P-RNTI / RA-RNTI / MSGB-RNTI / TC-RNTI. Or, when the terminal is in the idle / inactive state, the terminal behavior is the above terminal behavior 1. The detected PDCCH is Type3 CSS or USS, or is a PDCCH scrambled by C-RNTI, MCS-C-RNTI, CS-RNTI. Or, when the terminal is in the connected state, the terminal behavior is the above terminal behavior 2. In terminal behavior 4, when a terminal in the idle / inactive state starts random access, according to the network configuration (a setting that permits or does not permit the terminal to report its type), if the terminal reports its type, that is, its ability to support a bandwidth of up to 5 MHz, to the network in MSG1, or MSGA, or MSG3, the subsequent terminal behavior in MSG2, MSG3, and MSG4 transmissions is terminal behavior 2. Otherwise, the terminal behavior is terminal behavior 1.

[0066] When CORESET i, i≠0 and 5 MHz ≤ CORESET i = 20 MHz, when the terminal detects a PDCCH that schedules data in CORESET i, the following terminal behaviors 1' to 2' may occur to the terminal.

[0067] In terminal behavior 1', the terminal does not desire that the frequency domain resource range scheduled / assigned to the data exceeds 5 MHz, and the start position of the 5 MHz is the same as the start position of the current active BWP. In the terminal behavior 2', when the slot where the PDCCH is located and the slot where the scheduled data / reference signal is located do not overlap in the time domain, the terminal recognizes / desires that the resource allocation range in the frequency domain of the channel / signal scheduled by the control channel, for example, the data channel / reference signal, may exceed 5 MHz. Otherwise, the terminal behavior becomes the terminal behavior 1'.

[0068] As an alternative embodiment, the first frequency domain resource allocation range includes the frequency domain resource allocation range of a third control resource set associated with the control channel.

[0069] The third control resource set associated with the control channel may be a control resource set associated with the CSS corresponding to the control channel. Thus, it is possible to realize the determination of the bandwidth of the second frequency domain resource allocation range based on the bandwidth of the control resource set associated with the CSS corresponding to the control channel.

[0070] As an alternative embodiment, the time domain parameter of the control channel includes the time domain interval between the last time domain symbol and the first time domain symbol where the PDCCH received by the terminal on the control channel is located, and the first time domain symbol is the first time domain symbol where the transmission target is located.

[0071] As an alternative embodiment, the scheduling information of the control channel is the scheduling ability information of the terminal that schedules the transmission target for the control channel, which is the scheduling ability information for indicating whether to support the cross-slot scheduling between the control channel and the transmission target, and the cross-slot scheduling setting information of the network side that schedules the transmission target for the control channel, and at least one of the transmission mode information of the transmission target scheduled by the control channel.

[0072] In some embodiments, under the fourth condition, the bandwidth of the second frequency region resource allocation range is 5 MHz or less.

[0073] Here, the fourth condition is the CSS corresponding to the control channel is the CSS for scheduling the target SIB, the third control resource set is the control resource set for scheduling the target SIB, the bandwidth of the frequency region resource allocation range of the third control resource set is 5 MHz or less, the target SIB includes SIB1, the time domain interval is the first time or less, and the first time is the time required for the terminal to demodulate the PDCCH, the scheduling capability information indicates that the terminal does not support cross-slot scheduling between the control channel and the transmission target, or the terminal has not reported the capability information for supporting cross-slot scheduling between the control channel and the transmission target, the cross-slot scheduling setting information indicates that cross-slot scheduling between the control channel and the transmission target is not set, the transmission mode information indicates that the transmission target is not repeatedly transmitted, the transmission mode information may include at least one of indicating that frequency hopping transmission of the transmission target in the time domain is not performed.

[0074] The CSS for scheduling the above-mentioned target SIB may be Type0 CSS defined by the protocol. As a result, when the resource allocation range in the frequency domain of CORESET0 (or described as CORESET#0) associated with the Type0 CSS is 5 MHz or less, the terminal does not desire that the resource allocation range in the frequency domain of the channel or signal (e.g., data channel or reference signal) scheduled by the control channel exceeds 5 MHz, or it is possible to realize recognizing or desiring that the resource allocation range in the frequency domain of the channel or signal (e.g., data channel or reference signal) scheduled by the control channel is 5 MHz or less.

[0075] The fact that the above-mentioned time domain interval is less than or equal to the first time may mean that the time between the last orthogonal frequency division multiplex (OFDM) symbol where the PDCCH received by the terminal on the above-mentioned control channel is located and the first OFDM symbol where the transmission target scheduled thereby is located is less than or equal to the above-mentioned first time.

[0076] In some embodiments, the above-mentioned first time is determined by at least one of the capability of the terminal, the processing time of the physical downlink shared channel PDSCH set on the network side, the processing time of the physical uplink shared channel PUSCH set on the network side, the subcarrier spacing SCS of the PDCCH and the SCS of the above-mentioned transmission target.

[0077] The capabilities of the terminal may indicate whether the terminal supports a processing time that is more relaxed than the PDSCH / PUSCH processing time capability 1 (which may also be referred to as Cap#1), and in the case of support, the first time is a processing time that is more relaxed than the PDSCH / PUSCH processing time capability 1.

[0078] The processing time of PDSCH / PUSCH set on the network side as described above may be one of the processing time Cap#1, Cap#2, and Cap#3, where Cap#2 is a processing time other than Cap#1 and Cap#3. The first time may be the processing time of PDSCH / PUSCH, or may be a processing time that is more relaxed than the processing time of PDSCH / PUSCH.

[0079] In some embodiments, the first time may be the smaller of the subcarrier spacing SCS of the PDCCH and the SCS of the transmission target.

[0080] The fact that the above scheduling capability information indicates that the terminal does not support cross-slot scheduling between the control channel and the transmission target means that the terminal does not support cross-slot scheduling, that is, the terminal does not support that the slot where the control channel is located and the data channel or reference signal scheduled by it are in the same slot, or the terminal does not support that the slot where the control channel is located and the slot where the data channel or reference signal scheduled by it are located overlap in the time domain.

[0081] The fact that the above terminal has not reported the capability information to support cross-slot scheduling between the control channel and the transmission target may mean that when the terminal does not support cross-slot scheduling between the control channel and the transmission target, it has not reported the capability information to support cross-slot scheduling between the control channel and the transmission target.

[0082] That the above-described cross-slot scheduling setting information indicates that cross-slot scheduling for the control channel and the transmission target is not set means that the network side has not set cross-slot scheduling, that is, the slot where the control channel is located and the data channel or reference signal to be scheduled therewith are in the same slot, or the slot where the control channel is located and the slot where the data channel or reference signal to be scheduled therewith is located overlap in the time domain.

[0083] That the above-described transmission mode information indicates that the transmission target is not repeatedly transmitted may mean that the data or reference signal scheduled by the control channel is not repeatedly transmitted, and that the above-described transmission mode information indicates that frequency hopping transmission of the transmission target in the time domain is not performed may mean that frequency hopping transmission of the data or reference signal scheduled by the control channel in the time domain is not performed.

[0084] In this embodiment, under the fourth condition, it is possible to realize determining that the bandwidth of the second frequency region resource allocation range is 5 MHz or less.

[0085] In some embodiments, under the fifth condition, the bandwidth of the second frequency region resource allocation range is 5 MHz or less, or the bandwidth of the second frequency region resource allocation range is 20 MHz or less.

[0086] That the bandwidth of the second frequency region resource allocation range is 5 MHz or less, or the bandwidth of the second frequency region resource allocation range is 20 MHz or less under the above-described fifth condition means that under the fifth condition, it may be recognized or understood that the resource allocation range of the terminal in the frequency region of the transmission target may exceed 5 MHz.

[0087] Here, the fifth condition is The CSS corresponding to the control channel is the CSS for scheduling the target SIB, the third control resource set is the control resource set for transmitting the target system information block SIB, the bandwidth of the frequency domain resource allocation range of the third control resource set is more than 5 MHz, the target SIB includes SIB1, and the time domain interval is equal to or more than a first time, and the first time is the time required for demodulating the PDCCH by the terminal, and the scheduling capability information indicates that the terminal supports cross-slot scheduling between the control channel and the transmission target, and the cross-slot scheduling setting information indicates that cross-slot scheduling between the control channel and the transmission target is set, and the transmission mode information indicates that the transmission target is repeatedly transmitted and the bandwidth of the frequency domain resource range of a single nominal transmission or a single actual transmission is 5 MHz or less, and the transmission mode information indicates that multi-slot transmission (TB processing over multiple slots) by the same transmission block of the transmission target is performed and the bandwidth of the frequency domain resource range of a single slot transmission is 5 MHz or less, and the transmission mode information may include at least one of indicating that frequency hopping transmission in the time domain of the transmission target is performed and the bandwidth of the frequency domain resource range for each hopping transmission is 5 MHz or less.

[0088] The fact that the bandwidth of the frequency domain resource allocation range of the third control resource set described above is more than 5 MHz may mean that the resource allocation range in the frequency domain of CORESET0 associated with the Type0 CSS of the control channel is more than 5 MHz.

[0089] The fact that the above-mentioned time domain interval is equal to or greater than the first time may mean that the time between the last OFDM symbol in which the PDCCH received by the terminal on the above-mentioned control channel is located and the first OFDM symbol in which the transmission target is located is equal to or greater than the first time.

[0090] Here, for the above-mentioned first time, reference may be made to the corresponding description in the above-mentioned embodiment, and detailed description is omitted here.

[0091] The fact that the above-mentioned scheduling capability information indicates that the terminal supports cross-slot scheduling between the control channel and the transmission target may mean that the terminal supports the ability that the control channel and the received transmission target are not located in the same slot, or that the slot in which the control channel is located and the slot in which the transmission target is located do not overlap in the time domain.

[0092] The fact that the above-mentioned cross-slot scheduling setting information indicates that cross-slot scheduling between the control channel and the transmission target is set may mean that the network side has set cross-slot scheduling, that is, the control channel and the transmission target are not located in the same slot, or that the slot in which the control channel is located and the slot in which the transmission target is located do not overlap in the time domain.

[0093] In some embodiments, the frequency domain resources of different nominal transmissions or different actual transmission frequency domain resource ranges are different, and / or the frequency domain resources of different slot transmission frequency domain resource ranges are different, and / or the frequency domain resources of different hopping transmission frequency domain resource ranges are different.

[0094] For example, for the transmission target, repeated transmission or multi-slot transmission (TB processing over multiple slots) by one transmission block is performed, and the frequency domain resource range allocated to a single nominal repeated transmission or a single actual repeated transmission or a single slot is 5 MHz or less. However, the frequency domain resource ranges allocated to different nominal repeated transmissions or different actual repeated transmissions or different slots may be different 5 MHz. Also, for example, frequency hopping transmission of the transmission target in the time domain is performed, and the frequency domain resource range allocated for each frequency hopping transmission is 5 MHz or less. However, the frequency domain resource ranges between different frequency hoppings may be different 5 MHz.

[0095] As an alternative embodiment, the method further includes: Based on reference information, determining a frequency domain position of the second frequency domain resource allocation range by the terminal, where the reference information includes: The frequency domain resource boundary of the fourth control resource set for scheduling a target SIB including SIB1; The frequency domain resource boundary of the active bandwidth part BWP; The frequency domain resource boundary of the initial BWP; The frequency domain resource boundary where the control channel is located; The frequency domain resource boundary set on the network side; The index information of the transmission target; and includes at least one of them.

[0096] In some embodiments, the step of determining the frequency domain position of the second frequency domain resource allocation range may be to determine the frequency domain start position of the second frequency domain resource allocation range. In this way, the specific position of the frequency domain of the second frequency domain resource allocation range can be determined by the start position and the bandwidth.

[0097] In some embodiments, the step of determining the frequency domain position of the second frequency domain resource allocation range may be to determine the frequency domain end position of the second frequency domain resource allocation range, so that the specific position of the frequency domain of the second frequency domain resource allocation range can be determined by the end position and the bandwidth.

[0098] In some embodiments, the step of determining the frequency domain position of the second frequency domain resource allocation range may be to determine the discrete frequency domain position of the second frequency domain resource allocation range.

[0099] It should be noted that in the embodiments of the present application, it is not limited to the terminal determining the frequency domain position of the second frequency domain resource allocation range based on the reference information. For example, in some embodiments, the correspondence between the bandwidth and the frequency domain position may be set in advance. That is, when the bandwidth of the second frequency domain resource allocation range is determined, the frequency domain position of the second frequency domain resource allocation range can be directly determined based on the bandwidth.

[0100] In some embodiments, the fourth control resource set includes a control resource set of CSS for scheduling the target SIB including SIB1.

[0101] The CSS of the target SIB may be a CSS set, for example, a Type0-PDCCH CSS set, and the fourth control resource set may be CORESET0 where the Type0-PDCCH CSS set is located.

[0102] In some embodiments, the frequency domain resource boundary where the control channel is located includes at least one of the frequency domain resource boundary where the PDCCH received on the control channel is located and the frequency domain resource boundary of the control resource set where the PDCCH received on the control channel is located.

[0103] In some embodiments, the frequency domain resource boundary includes a starting PRB or an ending PRB.

[0104] For example, if the terminal recognizes or desires that the resource allocation range in the frequency domain of the transmission target is 5 MHz or less, the terminal determines the specific position within the 5 MHz range (i.e., the starting PRB of the 5 MHz is the target PRB) based on at least one of the starting PRB or the ending PRB of CORESET0 where the Type0-PDCCH CSS set is located, the starting PRB or the ending PRB of the active BWP or the initial BWP, the starting PRB or the ending PRB where the detected PDCCH for scheduling the transmission target is located, and the starting PRB or the ending PRB of the CORESET where the detected PDCCH for scheduling the transmission target is located.

[0106] TIFF2025523491000003.tif73170

[0107] In some embodiments, the index information of the transmission target may include at least one of the time domain index of the transmission target, the frequency hopping count index of the transmission target, and the transmission count index where the transmission target is located.

[0108] TIFF2025523491000004.tif24170

[0109] In this embodiment, it is possible to determine the frequency domain position of different second frequency domain resource allocation ranges based on the index. Specifically, it is possible to determine the frequency domain starting position of the second frequency domain resource allocation range. For example, different starting PRBs are determined based on the index. ​

[0110] In some embodiments, when the time domain index, the frequency hopping count index, or the transmission count index is even, the starting PRB of the second frequency domain resource allocation range is the starting PRB.

[0111] In some embodiments, when the time domain index, the frequency hopping count index, or the transmission count index is odd, the starting PRB of the second frequency domain resource allocation range is the combination of the starting PRB and the resource block RB offset, or when the time domain index, the frequency hopping count index, or the transmission count index is odd, the starting PRB of the second frequency domain resource allocation range is determined based on the ending PRB.

[0114] By determining the frequency domain position of the second frequency domain resource allocation range based on the above-mentioned reference information, the terminal can know in advance the target frequency domain position (for example, know which 5 MHz to transmit on), thereby the terminal can relax the buffer requirements of the terminal and can also save power.

[0115] As an example, it is as follows.

[0116] For example, for the SCS of CORESET0 being 30 KHz, and its bandwidth > 5 MHz, the detected aggregation level (AL) of the PDCCH being 8, and for the SIB1 PDSCH scheduled by CORESET0, if the terminal can know where / how on which 5 MHz the SIB1 is transmitted, the buffer requirements of the terminal can be relaxed and power can also be saved.

[0117] In the scenario shown in FIG. 3, for the 5 MHz for scheduling SIB1, its starting PRB is the starting PRB of CORESET0. The terminal receives the SIB1 PDSCH in slot0 and does not need to receive the SIB1 PDSCH in slot1.

[0119] TIFF2025523491000008.tif31170

[0120] As an alternative embodiment, the method further includes the step of the terminal receiving at the target resource and storing all received transmissions, wherein the frequency domain resources of the target resource include the second frequency domain resource range, and the time domain resources of the target resource include at least Y symbols, and Y is a positive integer.

[0121] The above transmission may be a downlink transmission, may be a downlink data transmission such as PDSCH, or may be a downlink signaling such as SIB1 or PDCCH.

[0122] The above step of the terminal receiving at the target resource and storing all received transmissions may be that the terminal receives all transmissions at the target resource and stores all received transmissions. For example, when the terminal receives or detects potential PDCCH in slot ns, the terminal receives all transmissions at the target resource and stores all received transmissions.

[0123] In some embodiments, the starting position of the second frequency domain resource range is the starting PRB of the control resource set where the PDCCH to be received by the terminal is located, or the starting position of the second frequency domain resource range is the starting PRB of the active BWP or the initial BWP, and the active BWP or the initial BWP includes all or part of the resources in the control resource set where the PDCCH to be received by the terminal is located.

[0124] The control resource set where the above-mentioned PDCCH to be received by the terminal is located may be the control resource set where the PDCCH detected by the terminal is located, and the above-mentioned PDCCH to be received by the terminal may be referred to as the PDCCH to be detected by the terminal.

[0125] For example, the terminal receives and stores all transmissions of 5 MHz in the frequency domain, and the starting position of the 5 MHz is the starting PRB of the CORESET where the PDCCH detected by the terminal is located, or the starting PRB of the active BWP or the initial BWP, and the active BWP or the initial BWP includes all or part of the frequency domain resources of the CORESET where the PDCCH to be detected is located.

[0126] In some embodiments, the starting position of the Y symbols is the first symbol or the last symbol where the PDCCH received on the control channel is located, where the value of Y is equal to the number of symbols required for demodulating the PDCCH by the terminal, or the value of Y is equal to the number of symbols in one slot minus the symbol index - 1 of the first symbol where the PDCCH is located.

[0127] For example, the terminal receives and stores at least Y symbols in the time domain. The start position of the Y symbols is the first or last OFDM symbol where the PDCCH is located in the detected control channel. The value of Y is all the OFDM symbols in one slot, or the value of Y is the number of symbols in one slot minus the symbol index -1 of the first symbol where the PDCCH is located, or the value of Y is determined by the first time described in the above embodiment, i.e., the time required for the terminal to demodulate the PDCCH.

[0128] By receiving on the target resource and storing all the received transmissions, it can be guaranteed that the terminal can receive the transmissions corresponding to the terminal.

[0129] As an example, it is as follows.

[0130] For example, the SCS of CORESET0 is 30KHz, and its bandwidth > 5MHz, and the detected PDCCH aggregation level AL = 8. For the SIB1 PDSCH scheduled by CORESET0, as shown in FIG. 6, when the UE does not know where / which 5MHz the SIB1 is transmitted on, the terminal needs to receive and store all the transmissions of 5MHz in the frequency domain in all the OFDM symbols in slot 0 and slot 1.

[0131] In an embodiment of the present application, a terminal determines related information of a control channel, where the related information of the control channel includes at least one of a first frequency domain resource allocation range of the control channel, a time domain parameter of the control channel, and scheduling information of the control channel. The terminal determines a bandwidth of a second frequency domain resource allocation range based on the related information. The second frequency domain resource allocation range is a frequency domain resource allocation range of a transmission target, and the transmission target is an object transmitted and received by the terminal based on the received control channel. The transmission target includes at least one of a channel and a signal. Here, the bandwidth of the second frequency domain resource allocation range is 5 MHz or less, or the bandwidth of the second frequency domain resource allocation range is 20 MHz or less. In this way, it is possible to realize the determination of the bandwidth of the second frequency domain resource allocation range based on the related information of the control channel.
