[0032] Figure 1 1 is a schematic diagram of an example communication network 100 in which embodiments of the present disclosure may be implemented. Figure 1 As shown, the communication network 100 may include a network device 110 and a terminal device 120 served by the network device 110. It should be understood that Figure 1 The number of devices in is given for illustrative purposes and does not imply any limitation of the present disclosure. The communication network 100 may include any suitable number of network devices and / or terminal devices suitable for implementing the present disclosure.
[0033] like Figure 1 As shown, the network device 110 can communicate with the terminal device 120 via a downlink channel such as a wireless communication downlink channel, and the terminal device 120 can communicate with the network device 110 via an uplink channel such as a wireless communication uplink channel. For example, the network device 110 can send resource scheduling information to the terminal device 120 via a downlink control channel such as a physical downlink control channel (PDCCH), and the terminal device 120 can perform data transmission or reception based on the resource scheduling information. In some embodiments, the network device 110 can send uplink resource allocation information to the terminal device 120 in the PDCCH, and the terminal device 120 can send uplink data in the PUSCH based on the uplink resource allocation information. In some alternative embodiments, the network device 110 can send downlink resource allocation information to the terminal device 120 in the PDCCH, and the terminal device 120 can receive downlink data in the PDSCH based on the downlink resource allocation information.
[0034] The communications in the communication network 100 may conform to any suitable standard, including but not limited to: Global System for Mobile Communications (GSM), Long Term Evolution (LTE), LTE Evolution, Advanced LTE (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), GSM EDGE Radio Access Network (GERAN), Machine Type Communication (MTC), etc. In addition, the communications may be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include but are not limited to: first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols, sixth generation (6G) communication protocols, or more communication protocols.
[0035] As described above, new parameter sets for operating in the frequency range of 52.6 GHz to 71 GHz have been studied, and in this case, timeline-related aspects adapted to each new parameter set should also be studied.
[0036] More specifically, given the feature reusability in the requirements for NR above 52.6 GHz in TR38.807 and design commonality with existing NR specifications, it would be good to be able to support the features of FR1 and FR2 defined in NR with minimal changes (if possible) and to support a common design structure that can support a variety of use cases.
[0037] In this sense, further considerations of integer ratios between the clock rates for NR below 52.6 GHz and NR above 52.6 GHz should be investigated. One possibility to achieve this is to keep the NR parameter set scaling principle, but extend to higher parameter sets, i.e., Δf = 2μ × 15 kHz, where μ has a suitable range of possible integer values. For example, more subcarrier spacings (SCSs) have been proposed, such as 480 KHz, 960 KHz, 1920 KHz, and 3840 KHz, and the corresponding number of available subcarriers, number of discrete Fourier transform (IDFT) points, and sampling frequency have also been proposed.
[0038] However, the current sampling time still cannot be suitable for the new parameter set, the current range defined for K0, K1 and K2 is too small to schedule all time slots in carrier frequencies above 52.6 GHz, and the current N1 and N2 defined based on SCS cannot be suitable for the new parameter set. Here, K0 represents the timing between downlink resource grant on PDCCH and downlink data transmission on PDSCH, K1 represents the timing between downlink data reception and hybrid automatic repeat request acknowledgment (HARQ-ACK) transmission on PDSCH, and K2 represents the timing between uplink resource grant on PDCCH and uplink data transmission on PUSCH. N1 represents the PDSCH decoding time of the terminal device, and N2 represents the PUSCH preparation time of the terminal device.
[0039] In view of the above, embodiments of the present disclosure provide an improved communication scheme by extending the definition of time units and the ranges of K0, K1, K2, N1 and N2. First, the extension of these parameters will be described below.
[0040] Time unit (hereinafter also referred to as second information)
[0041] In the current NR Release 15 and Release 16, the time unit Tc is defined as equation (1).
[0042] T C =1 / (Δf max ·N f ) (1)
[0043] where Δf max =480·10 3 Hz and N f =4096. Constant κ = T s / T c =64, where T s =1 / (Δf ref ·N f,ref ), Δf ref =15·10 3 Hz and N f,ref =2048.
[0044] According to an embodiment of the present disclosure, the time unit is extended to change according to the parameter set used. In some embodiments, the scaling factor s (hereinafter also referred to as the second scaling factor) can be determined based on the sampling frequency and the associated mapping from a set of SCS to a set of scaling factors, and the time unit is determined based on the second scaling factor. In the present disclosure, the sampling frequency refers to a parameter such as Δf maxThe group of SCSs is applicable to the new parameter set. In some embodiments, the group of SCSs may include at least one SCS equal to or greater than a first predetermined value. In some embodiments, the first predetermined value may be selected from the group including 480KHz, 960KHz, 1920KHz and 3840KHz.
[0045] In some example embodiments, Δf max and κ can be defined as equation (2) and equation (3), respectively.
[0046] Δf max =480·10 3 (1+s) (2)
[0047] κ=T s / T c =64(1+s) (3)
[0048] where s is based on the SCS used.
[0049] In some embodiments, s may be in the range [0, 0.5, 1, 1.5, 2 ...] or a portion of this range. In this case, in some embodiments where the sampling frequency is the same as the SCS used, the mapping between SCS and s may be represented as Table 1.
[0050] Table 1 Mapping between SCS and s (where the sampling frequency is the same as the SCS used)
[0051] SCS s 480KHz 0 720KHz 0.5 960KHz 1 1200KHz 1.5
[0052] In some embodiments where the sampling frequency is higher than the SCS used, the mapping between SCS and s may be represented as in Table 2.
[0053] Table 2 Mapping between SCS and s (where the sampling frequency is higher than the SCS used)
[0054] SCS s 480KHz 0.5 720KHz 1 960KHz 1.5 1200KHz 2
[0055] In some alternative embodiments, s may be in the range [0, 1, 2, 3, 4 ...] or a portion of this range. In this case, in some embodiments where the sampling frequency is the same as the SCS used, the mapping between SCS and s may be represented as Table 3.
[0056] Table 3 Mapping between SCS and s (where the sampling frequency is the same as the SCS used)
[0057] SCS s 480KHz 0 960KHz 1 1440KHz 2 1920KHz 3 2400KHz 4
[0058] In some embodiments where the sampling frequency is higher than the SCS used, the mapping between SCS and s may be represented as in Table 4.
[0059] Table 4 Mapping between SCS and s (where the sampling frequency is higher than the SCS used)
[0060]
[0061]
[0062] In some alternative example embodiments, Δf max and κ can be defined as equation (4) and equation (5) respectively.
[0063] Δf max =480·10 3 *2 s (4)
[0064] κ=T s / T c =64*2 s (5)
[0065] where s is based on the SCS used.
[0066] In some embodiments, s may be in the range [0, 1, 2, 3, ...] or a portion of this range. In this case, in some embodiments where the sampling frequency is the same as the SCS used, the mapping between SCS and s may be represented as Table 5.
[0067] Table 5 Mapping between SCS and s (where the sampling frequency is the same as the SCS used)
[0068] SCS s 480KHz 0 960KHz 1 1920KHz 2 3840KHz 3
[0069] In some alternative example embodiments, Δf max and κ can be defined as equation (6) and equation (7), respectively.
[0070] Δf max =480·10 3 *2 (s+1) (6)
[0071] k=T s / T c =64*2 (s+1) (7)
[0072] Where s is based on the SCS used. In some embodiments, s may be in the range [0, 1, 2, 3 ...] or a portion of the range. In this case, in some embodiments where the sampling frequency is 2 times the SCS used, the mapping between SCS and s may be as shown in Table 6.
[0073] Table 6 Mapping between SCS and s (where the sampling frequency is twice the SCS used)
[0074]
[0075]
[0076] So far, the above describes the time unit that changes according to the parameter set used. It should be noted that the examples listed above are only for illustration, and any other suitable manner similar to the above is also feasible.
[0077] Alternatively, the time unit may be extended to a fixed value suitable for a new parameter set. In some embodiments, the time unit may be predefined for at least one subcarrier spacing equal to or greater than a first predetermined value. In some embodiments, the first predetermined value may be selected from a group consisting of 480 KHz, 960 KHz, 1920 KHz, and 3840 KHz.
[0078] For example, in some embodiments, the time unit T C_new They can be defined as equation (8) and equation (9) respectively.
[0079] T C_new =1 / (Δf max_new ·N f ) (8)
[0080] K new =T s / T C_new (9)
[0081] In some embodiments, Δf max _ new =960·10 3 And K new 128. In some alternative embodiments, Δf max_new =1920·10 3 And K new =256. In some alternative embodiments, Δf max_new =3840·10 3 And K new = 512. It should be noted that the values listed above are for illustration only, and any other suitable values are also possible.
[0082] The extended time unit according to an embodiment of the present disclosure can support a new parameter set while maintaining the original form of the equation, and enables NR to support a large bandwidth with a large subcarrier spacing in frequencies above 52.6 GHz.
[0083] K2 (hereinafter also referred to as the first time slot offset value)
[0084] According to the current specification in TS38.214, the time slot Ks in which the terminal device will send PUSCH is determined by K2 as
[0085]
[0086] where n is the time slot with scheduled DCI, K2 is based on the parameter set of PUSCH, and μ PUSCH and μ PDCCH They are the subcarrier spacing configurations for PUSCH and PDCCH respectively.
[0087] For example, in the case of carrier aggregation (CA) where the scheduled component carrier 1 (CC1) is 15KHz and the scheduled component carrier 2 (CC2) is 960KHz, as shown in FIG. Figure 2 As shown, Figure 2 A schematic diagram 200 illustrating uplink resource scheduling according to some embodiments of the present disclosure is shown, where CC1 210 schedules CC2 220 across carriers if CC1 210 and CC2 220 are frame aligned. The PDCCH duration is 3 symbols in CC1 and 192 symbols (up to 14 slots) in CC2. PUSCH processing time T proc,2 as follows.
[0088] T proc,2 =max((N2+d 2,1 )(2048+144)·κ2 -μ ·T C , d 2,2 ) (11)
[0089] Where T proc,2 Indicates the PUSCH processing time, d 2,1 and d 2,2 Represents the timing offset shown in TS38.214.
[0090] If N2 for 960KHz is 48 symbols and 4 time slots, then time slot Ks is determined by K2 as shown in equation (10), and K2 is selected from (0..32), PDCCH can only schedule time slots from 18 to 32 in CC2 220, but cannot schedule other time slots from 33 to 63.
[0091] According to an embodiment of the present disclosure, K2 is selected from a range (also referred to as a first range) for scheduling all time slots in a carrier frequency, such as in a component carrier (CC) in the case of CA. For example, all time slots from 0 to 63 in CC2 220 may be scheduled.
[0092] In some embodiments, the first range can be from a first starting value of zero to a first ending value equal to or greater than 64. For example, in some embodiments, K2 can be extended to (0..64). In some alternative embodiments, K2 can be extended to (0..128). In some alternative embodiments, K2 can be extended to (0..256). In some alternative embodiments, K2 can be extended to (0..1024).
[0093] For example, K2 may be configured via RRC signaling as follows.
[0094]
[0095] or
[0096]
[0097] In some alternative embodiments, a basic time slot offset value K2 (hereinafter also referred to as a second time slot offset value) and a scaling factor m (hereinafter also referred to as a first scaling factor) may be determined, and k2 may be determined based on the product of the basic time slot offset value and the scaling factor m. In some embodiments, the scaling factor m is a predetermined scaling factor selected from a set of predetermined scaling factors. For example, k2=INTEGER(0..32), and K2 may be defined as follows.
[0098] K2=k2*m=INTEGER(0..32*m), m=1, 2, 3, 4 (12)
[0099] Where m depends on the parameter set used. It should be noted that the value of m is not limited to the listed examples, and any other suitable value is also possible.
[0100] For example, K2 may be configured via RRC signaling as follows.
[0101]
[0102] In some alternative embodiments, a set of K2 values (hereinafter also referred to as a first set of time slot offset values) can be predefined, for example, a set of K2 values {(0..64), (0..128), (0..256)} can be predefined, and the index indicating K2 in the set of K2 values can be configured via RRC signaling.
[0103] With the extension of K2 according to an embodiment of the present disclosure, more uplink time slots can be scheduled and channel utilization can be increased.
[0104] K0 (hereinafter also referred to as the third time slot offset value)
[0105] According to the current specification in TS38.214, the time slot Ks' allocated for PDSCH is determined by K0 as
[0106]
[0107] where n is the time slot with scheduled DCI, K0 is based on the parameter set of PDSCH, and μ PDSCH and μ PDCCH They are the subcarrier spacing configurations for PDSCH and PDCCH respectively.
[0108] For example, in the case of carrier aggregation (CA) where the scheduled CC (CC1) is 15KHz and the scheduled CC (CC2) is 960KHz, Figure 3 As shown, Figure 3 A schematic diagram 300 illustrating downlink resource scheduling according to some embodiments of the present disclosure is shown, where CC1 310 schedules CC2 320 across carriers if CC1 310 and CC2 320 are frame aligned. The PDCCH duration is 3 symbols in CC1 and 192 symbols (14 slots) in CC2. K0 may be RRC configured or use a default TDRA table. If K0 is selected from (0..32), the PDCCH may only schedule slots from 14 to 32 in CC2 320, and may not schedule other slots from 33 to 63.
[0109] According to an embodiment of the present disclosure, K0 is selected from a range (also referred to as a third range) for scheduling all time slots in a carrier frequency, such as in a CC in the case of CA. For example, all time slots from 0 to 63 in CC2 320 may be scheduled. In some embodiments, the third range may be from a third starting value of zero to a third ending value equal to or greater than 64. For example, in some embodiments, K0 may be extended to (0..64). In some alternative embodiments, K0 may be extended to (0..128). In some alternative embodiments, K0 may be extended to (0..256).
[0110] For example, K0 may be configured via RRC signaling as follows.
[0111]
[0112] or
[0113]
[0114] In some alternative embodiments, a basic time slot offset value k0 (hereinafter also referred to as a fourth time slot offset value) and a scaling factor m' (hereinafter also referred to as a third scaling factor) may be determined, and k0 may be determined based on the product of the basic time slot offset value and the scaling factor m'. In some embodiments, the scaling factor m' is a predetermined scaling factor selected from a set of predetermined scaling factors. For example, k0=INTEGER(0..32), and K0 may be defined as follows.
[0115] K0=k0*m'=INTEGER(0..32*m'),m'=1,2,3,4 (14)
[0116] where m' depends on the parameter set used. It should be noted that the value of m' is not limited to the listed examples, and any other suitable value is also possible.
[0117] For example, K0 may be configured via RRC signaling as follows.
[0118]
[0119] In some alternative embodiments, a set of K0 values (hereinafter also referred to as a second set of time slot offset values) can be predefined, for example, a set of K0 values {(0..64), (0..128), (0..256)} can be predefined, and the index indicating K0 in the set of K0 values can be configured via RRC signaling.
[0120] By extending K0 according to an embodiment of the present disclosure, more downlink time slots can be scheduled and channel utilization can be increased.
[0121] K1 (hereinafter also referred to as the fifth time slot offset value)
[0122] In the current specification of TS 38.213, for DCI formats other than format 1_0, HARQ-ACK is sent according to dl-DataToUL-ACK or dl-DataToUL-ACKForDCIFormat1_2 (K1), but the range of these two values is (0..15), which limits the scheduling time. K1 is specified in TS 38.331 as follows. dl-DataToUL-ACKSEQUENCE(SIZE(1..8))OF INTEGER(0..15)OPTIONAL,--Need M.
[0123] According to an embodiment of the present disclosure, K1 is selected from a range (also referred to as a fifth range) of all time slots in a scheduling carrier frequency (such as in a CC). In some embodiments, the fifth range may be a fifth starting value of zero to a fifth ending value equal to or greater than 31. For example, the range of K1 may be extended to (1…P), where P may be any one of 31, 63, 127, 255, 511, or 1023. In some embodiments, P depends on the capabilities of the terminal device. In some embodiments, P depends on the parameter set used. K1 may be specified as follows. dl-DataToUL-ACK SEQUENCE(SIZE(1..8))OF INTEGER(0..P)OPTIONAL,--Need M.
[0124] In some alternative embodiments, a set of K1 values may be defined, and each K1 value has a different range. In some embodiments, the capabilities of the terminal device are used to select a K1 value from the set of K1 values.

[0150] It can be seen that N2 is determined by the PUSCH processing capability and SCS. When a new parameter set is introduced, the value of N2 should be redefined.
[0151] According to an embodiment of the present disclosure, the value of N2 may be defined as in Table 13 and Table 14.

[0161] By utilizing the flexible configuration of N1 and N2 through RRC signaling according to an embodiment of the present disclosure, the terminal device can adjust its processing time based on the network configuration. It should be noted that although the above description is for cross-carrier scheduling, the present solution can also be applied to self-carrier scheduling.
[0162] So far, the expansion of these parameters is as described above. The corresponding operations involving these parameters will be described below. Figure 4 FIG. 4 is a schematic diagram of a process 400 for sending and receiving data according to an embodiment of the present disclosure. For the purpose of discussion, reference will be made to FIG. Figure 1 Process 400 is described. Process 400 may involve Figure 1 Shown are a network device 110 and a terminal device 120. Process 400 is divided into two separate parts, namely an uplink scheduling process 410-415 and a downlink scheduling process 420-426.
[0163] Uplink Scheduling Process
[0164] like Figure 4As shown, the network device 110 determines 410 uplink resource allocation information indicating K2 defined according to the present disclosure. Upon determining K2, the network device 110 sends 411 uplink resource allocation information to the terminal device 120. For example, the network device 110 may send the uplink resource allocation information in a DCI via a downlink channel such as a PDCCH.
[0165] In some embodiments, upon receiving the uplink resource allocation information, the terminal device 120 may determine 412 a preparation time N2 for a channel for transmitting uplink data such as a PUSCH, N2 being defined in accordance with the present disclosure. The terminal device 120 may also determine 413 a corresponding time unit based on the SCS of the channel, the time unit being defined in accordance with the present disclosure. Based on the determined N2 and the time unit, the terminal device 120 may determine 414 whether the uplink data is ready to be sent. The determination 414 may be performed, for example, according to equation (11) above. Other details regarding the determination 414 are similar to those in Section 6.4 of TS 38.214 and are therefore not repeated here.
[0166] After determining that the uplink data is ready to be sent, the terminal device 120 sends 415 the uplink data. In some embodiments, the terminal device 120 can determine a time slot such as Ks allocated for the uplink data based on K2, for example according to the above formula (10), and send 415 the uplink data in the determined time slot via an uplink channel such as PUSCH.
[0167] Downlink Scheduling Process
[0168] like Figure 4 As shown, the network device 110 determines 420 downlink resource allocation information indicating K0 defined according to the present disclosure. Upon determining K0, the network device 110 sends 421 the downlink resource allocation information to the terminal device 120. For example, the network device 110 may send the downlink resource allocation information in a DCI via a downlink channel such as a PDCCH.
[0169] Upon receiving the downlink resource allocation information, the terminal device 120 receives 422 downlink data based on the downlink resource allocation information. For example, the terminal device 120 may determine a time slot allocated to the downlink data, such as Ks', based on K0, for example according to the above equation (13), and receive the downlink data in the determined time slot.
[0170] In some embodiments where the downlink resource allocation information also indicates K1, the terminal device 120 may determine 423 a decoding time N1 for a channel for receiving downlink data such as a PDCCH, N1 being defined above according to the present disclosure. The terminal device 120 may also determine 424 a corresponding time unit based on the SCS of the channel, the time unit being defined above according to the present disclosure. Based on the determined N1 and the time unit, the terminal device 120 may determine 425 whether the downlink data has sufficient processing time to be received. The determination 425 may be performed, for example, according to the following equation (15).
[0171] T proc,1 =(N1+d 1,1 )(2048+144)·κ2 -μ ·T c (IS)
[0172] Where T proc,1 Indicates the PDSCH processing time, d 1,1 represents the timing offset shown in TS 38.214. Other details about the determination 425 are similar to Section 5.3 of TS 38.214 and are therefore not repeated here.
[0173] Upon determining that the downlink data has sufficient processing time to be received, the terminal device 120 may send 426 a HARQ-ACK for reception of the downlink data. In some embodiments, the terminal device 120 may determine a time slot allocated for HARQ-ACK transmission based on K1 and send the HARQ-ACK in the determined time slot via an uplink channel such as PUCCH or PUSCH.
