Description

Technical Field

[0001] This application belongs to the field of wireless communication, specifically relating to a downlink transmission method, terminal, and network-side equipment. Background Technology

[0002] With the development of communication technology, a new type of terminal device—the reduced capability (RedCap) terminal—has been introduced into the New Radio (NR) system. These terminals have narrower bandwidth or fewer receiving antennas than ordinary terminals. For example, Release 18 discloses that the maximum bandwidth capability of a RedCap terminal in frequency range 1 (FR1) is only 5MHz. This results in a lower terminal capability for RedCap terminals. In this situation, ensuring that RedCap terminals can effectively process multiple received downlink transmissions (especially when downlink transmissions overlap in the time domain but not in the frequency domain) to ensure communication quality remains a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0030] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0031] like Figure 2 The diagram shown illustrates a flowchart of a downlink transmission method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0032] S210, if the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but not in the frequency domain (e.g., located in different Physical Resource Blocks (PRBs)), the terminal determines the processing method of the first downlink transmission and the second downlink transmission based on whether the total frequency domain resources occupied (or used) by the first downlink transmission and the second downlink transmission are greater than (or exceed) the terminal's bandwidth capacity.

[0033] The bandwidth capability (or baseband bandwidth) of the terminal can be understood as the terminal's ability to receive, process, or buffer signals. Therefore, as a possible implementation, the bandwidth capability of the terminal may include, but is not limited to, at least one of the following (a)-(c).

[0034] (a) The receiving bandwidth N1 of the terminal, wherein N1 is not greater than 20MHz, such as 5MHz, 10MHz, etc.

[0035] (b) The cache bandwidth N2 of the terminal, wherein N2 is not greater than 20MHz, such as 5MHz, 10MHz, etc.

[0036] (c) The processing bandwidth N3 of the terminal, wherein N3 is not greater than 5MHz, such as 1MHz, 5MHz, etc.

[0037] It should be noted that the terminal mentioned in this embodiment can be a Redcap terminal with reduced capabilities, a terminal with a bandwidth capability of only 5MHz, or a terminal with a bandwidth capability of less than 20MHz, etc.

[0038] Based on this, assuming that when the network-side device sends the first downlink transmission and the second downlink transmission, there is a situation where the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but not in the frequency domain, then for the terminal described in this embodiment, due to its reduced or limited capabilities, it will be unable to process the received downlink transmissions that overlap in the time domain but not in the frequency domain according to the downlink transmission processing methods in related technologies. To address this problem, this embodiment defines the terminal's behavior by judging the relationship between the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission and the terminal's bandwidth capability, such as whether the terminal demodulates or does not demodulate the first downlink transmission and the second downlink transmission, so that the terminal can effectively process multiple received downlink transmissions, thereby ensuring communication quality.

[0039] Of course, when the terminal determines the processing method of the first downlink transmission and the second downlink transmission based on whether the total frequency domain resources occupied (or used) by the first downlink transmission and the second downlink transmission are greater than the terminal's bandwidth capacity, it may determine whether to demodulate or not demodulate the first downlink transmission and the second downlink transmission based on whether the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission in the first time unit are greater than the terminal's bandwidth capacity (such as receiving bandwidth, buffer bandwidth, and processing bandwidth) in the second time unit. The first time unit and the second time unit may each include one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, one or more time slots, one or more sub-time slots, etc., and the first time unit may be the same as or different from the second time unit.

[0040] It should be noted that the number of symbols, time slots, or sub-time slots included in the first time unit and the second time unit are different for different subcarrier spacings (SCS).

[0041] In addition, the first downlink transmission and the second downlink transmission mentioned in this embodiment can be a physical downlink shared channel (PDSCH), a physical broadcast channel (PBCH), etc., and are not limited here.

[0042] In this embodiment, when the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but not in the frequency domain, the behavior of the terminal is defined by judging the relationship between the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission and the bandwidth capability of the terminal, so that the terminal can effectively process the received multiple downlink transmissions and thus ensure communication quality.

[0043] like Figure 3 The diagram shown illustrates a flowchart of a downlink transmission method 300 provided in an exemplary embodiment of this application. This method 300 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0044] S310, if the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but not in the frequency domain, the terminal determines the processing method of the first downlink transmission and the second downlink transmission based on whether the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal.

[0045] The bandwidth capability of the terminal is N, where N is less than 20MHz.

[0046] It is understood that, in addition to referring to the relevant description in method embodiment 200, as a possible implementation, when the terminal determines the processing method of the first downlink transmission and the second downlink transmission based on whether the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, the implementation process may include, but is not limited to, the following: Figure 3 S311 and S312 are shown.

[0047] S311, if the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, the processing method determined by the terminal includes the first processing method. The first processing method may include, but is not limited to, at least one of the following methods 1-5.

[0048] Method 1, expect (or anticipate), or prioritize demodulation of the third downlink transmission.

[0049] The third downlink transmission is the downlink transmission scheduled (or scrambled) by the first radio network temporary identifier (RNTI) in the first downlink transmission and the second downlink transmission.

[0050] Optionally, when the terminal is in an idle state (e.g., Radio Resource Control (RRC) - Idle) or an inactive state (e.g., RRC - Inactive), the first RNTI may include Random Access (RA) RNTI, Message B (Msg B) RNTI, or Temporary Cell (TC) RNTI, etc. When the terminal is in a connected state (or active state), the first RNTI may include System Information (SI) RNTI, etc.

[0051] In other words, when the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, if the terminal is in an idle or inactive state, it expects (or anticipates) to be able to decode downlink transmissions scheduled or scrambled by RA-RNTI (or Msg B-RNTI or TC-RNTI), or the terminal preferentially decodes downlink transmissions scheduled or scrambled by RA-RNTI (or Msg B-RNTI or TC-RNTI). If the terminal is in a connected state, it expects (or anticipates) to be able to decode downlink transmissions scheduled or scrambled by SI-RNTI, or the terminal preferentially decodes downlink transmissions scheduled or scrambled by SI-RNTI.

[0052] Alternatively, the third downlink transmission is the downlink transmission with higher priority between the first downlink transmission and the second downlink transmission. In other words, when the first downlink transmission and the second downlink transmission overlap at least partially in the time domain, do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, the terminal expects (or anticipates) to be able to decode the downlink transmission with higher priority, or the terminal prioritizes decoding the downlink transmission with higher priority.

[0053] Based on this, in this embodiment, the terminal can determine the priority of the first downlink transmission and the second downlink transmission according to any one of the following (11)-(16).

[0054] (11) The priority of downlink transmissions scheduled by P-RNTI > the priority of downlink transmissions scheduled by SI-RNTI > the priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI.

[0055] (12) The priority of downlink transmissions scheduled by P-RNTI > the priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI > the priority of downlink transmissions scheduled by SI-RNTI.

[0056] (13) The priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI > the priority of downlink transmissions scheduled by P-RNTI > the priority of downlink transmissions scheduled by SI-RNTI.

[0057] (14) The priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI > the priority of downlink transmissions scheduled by SI-RNTI > the priority of downlink transmissions scheduled by P-RNTI.

[0058] (15) The priority of downlink transmissions scheduled by SI-RNTI > the priority of downlink transmissions scheduled by P-RNTI > the priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI.

[0059] (16) The priority of downlink transmissions scheduled by SI-RNTI > the priority of downlink transmissions scheduled by RA-RNTI or Msg B-RNTI or TC-RNTI > the priority of downlink transmissions scheduled by P-RNTI.

[0060] It is worth noting that, for the aforementioned (11)-(16), if the first downlink transmission and the second downlink transmission are scheduled by TC-RNTI and the other by RA-RNTI or Msg B-RNTI, then the terminal can autonomously determine which downlink transmission to demodulate first. That is, in this embodiment, the downlink transmission scheduled by RA-RNTI or Msg B-RNTI has a higher priority than the downlink transmission scheduled by TC-RNTI, or the downlink transmission scheduled by TC-RNTI has a higher priority than the downlink transmission scheduled by RA-RNTI or Msg B-RNTI.

[0061] Furthermore, when processing the first downlink transmission and the second downlink transmission according to priority, for another downlink transmission with lower priority, the terminal is not required to demodulate the downlink transmission with lower priority, or the terminal does not expect to demodulate the downlink transmission with lower priority, or the terminal can skip the downlink transmission with lower priority.

[0062] Method 2: Skip or do not expect (or do not anticipate) demodulation of the fourth downlink transmission.

[0063] The fourth downlink transmission is the downlink transmission scheduled or scrambled by the second RNTI in the first downlink transmission and the second downlink transmission.

[0064] Optionally, when the terminal is in an idle or inactive state, the second RNTI may include SI-RNTI or Paging (P)-RNTI; or, when the terminal is in a connected state, the second RNTI may include Cell C-RNTI, Modulation and Coding Scheme (MCS)-C-RNTI, or Configured Scheduling (CS)-RNTI.

[0065] In other words, if the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, the terminal, if in an idle or inactive state, skips (or does not expect) decoding downlink transmissions scheduled or scrambled by SI-RNTI or P-RNTI. If the terminal is in a connected state, it skips (or does not expect) decoding downlink transmissions scheduled or scrambled by SI-RNTI, or the terminal preferentially decodes downlink transmissions scheduled or scrambled by C-RNTI (or MCS-C-RNTI or CS-RNTI).

[0066] Alternatively, the fourth downlink transmission is the lower-priority downlink transmission between the first and second downlink transmissions. In other words, if the first and second downlink transmissions at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first and second downlink transmissions exceed the bandwidth capacity of the terminal, the terminal skips or does not expect to decode the lower-priority downlink transmission. It should be noted that in this implementation, the terminal determines the priority of the first and second downlink transmissions in a manner similar to that of method 1, as shown in (11)-(16) above, and will not be repeated here.

[0067] It is worth noting that the terminal's statement that it does not expect or skips the demodulation of the fourth downlink transmission can also be understood as the terminal not demodulating the fourth downlink transmission. Correspondingly, if the terminal does not demodulate the fourth downlink transmission, the network side will not receive or demodulate the corresponding information. For example, if the fourth downlink transmission is scheduled by RA-RNTI, the network side will not receive or demodulate the corresponding MSG3 transmission; if the fourth downlink transmission is scheduled by TC-RNTI, C-RNTI, MCS-C-RNTI, or CS-RNTI, the network side will not receive or demodulate the corresponding Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) transmission.

[0068] Furthermore, when determining the processing methods for the first downlink transmission and the second downlink transmission, the terminal can implement either method 1 or method 2 independently, or it can combine methods 1 and 2 to transmit the first downlink transmission and the second downlink transmission; no restrictions are imposed here.

[0069] Method 3: Demodulate the first downlink transmission and / or the second downlink transmission based on the terminal's own implementation information.

[0070] The terminal's own implementation information may be downlink transmission processing information preset inside the terminal at the factory, or communication process information initiated by the terminal, etc., without any restrictions.

[0071] For example, when the implementation information of the terminal itself is the downlink transmission processing information preset inside the terminal at the factory, the downlink transmission processing information preset inside the terminal may be such that when the first downlink transmission and the second downlink transmission at least partially overlap in the time domain, do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are greater than the bandwidth capacity of the terminal, the terminal prioritizes the downlink transmission scheduled or scrambled by a specified RNTI (such as SI-RNTI, C-RNTI, etc.), etc., without any restrictions.

[0072] For example, when the terminal's own implementation information indicates that the communication process is initiated by the terminal, the communication process initiated by the terminal can be a random access process, etc. In one implementation, assuming that the communication process initiated by the terminal is a random access process, then, when the terminal initiates a random access process, it demodulates the first downlink transmission and skips the second downlink transmission. The first downlink transmission is scheduled by a third RNTI, and the second downlink transmission is scheduled by a fourth RNTI. The third RNTI includes RA-RNTI, Msg B-RNTI, or TC-RNTI, and the fourth RNTI includes SI-RNTI, P-RNTI, C-RNTI, MCS-C-RNTI, CS-RNTI, Multicast Broadcast Service Control Channel (MCCH)-RNTI, or Group (G)-RNTI.

[0073] Method 4: Demodulate the first downlink transmission or the second downlink transmission based on the location information of the frequency domain resources occupied by the first downlink transmission and the second downlink transmission.

[0074] In one implementation, the terminal can demodulate a fifth downlink transmission, which is a downlink transmission in which the frequency domain resources occupied by the first downlink transmission and the second downlink transmission largely overlap with the specified frequency domain resources.

[0075] The specified frequency domain resources include at least one of the following: frequency domain resources occupied by the Synchronization Signal Block (SSB), frequency domain resources occupied by the Control Resource Set (CORSET#0), frequency domain resources predefined by the protocol, frequency domain resources configured by SI, and frequency domain resources configured by RRC information.

[0076] Method 5: If the first condition is met, demodulate the first downlink transmission and the second downlink transmission.

[0077] Optionally, the first condition may include, but is not limited to, at least one of the following (21)-(27).

[0078] (21) One of the first downlink transmissions and the second downlink transmission is scheduled by SI-RNTI or P-RNTI, and the other downlink transmission is scheduled by any one of SI-RNTI, P-RNTI, RA-RATI, or TC-RNTI.

[0079] (22) The first downlink transmission and the second downlink transmission are respectively scheduled by any one of SI-RNTI, P-RNTI, RA-RATI, and TC-RNTI.

[0080] (23) At least one of the first downlink transmission and the second downlink transmission is scheduled by SI-RNTI or P-RNTI.

[0081] (24) The total transport block (TB) size corresponding to the first downlink transmission and the second downlink transmission does not exceed a first predetermined value.

[0082] In one implementation, the first predetermined value is determined based on the capabilities of the terminal, that is, the first predetermined value depends on the capabilities of the terminal, and the terminal reports the first predetermined value to the network-side device after determining the first predetermined value to ensure communication consistency.

[0083] In another implementation, the first predetermined value can also be implemented by a protocol predefined or network agreement. For example, the first predetermined value may include: if the SCS is 30kHz, then the first predetermined value can be 5000 bits; if the SCS is 15kHz, then the first predetermined value can be 10000 bits.

[0084] (25) The total peak data rate of the first downlink transmission and the second downlink transmission does not exceed a second predetermined value.

[0085] Similar to the aforementioned first predetermined value, the second predetermined value can also be determined based on the terminal's capabilities, or it can be implemented through protocol predefinition or network agreement. Specifically, when the second predetermined value is implemented through protocol predefinition or network agreement, the second predetermined value can be 10 Mbps.

[0086] Furthermore, if the second predetermined value is determined based on the terminal's capabilities, the terminal can report the second predetermined value to the network-side device to ensure communication consistency.

[0087] (26) Do not receive the sixth downlink transmission within a predetermined number of time units after the target time unit, wherein the target time unit is the time unit in which the first downlink transmission and the second downlink transmission are located.

[0088] The sixth downlink transmission includes downlink transmissions scheduled by at least one of C-RNTI, MCS-C-RNTI, CS-RNTI, RA-RNTI, TC-RNTI, MCCH-RNTI, and G-RNTI. The downlink transmission may also be PDSCH, etc., and there is no limitation on it.

[0089] The time unit can be a time slot, a sub-time slot, a symbol, a subframe, etc., and there are no restrictions here.

[0090] The predetermined quantity can be determined based on the terminal's capabilities, or it can be predefined by the protocol or agreed upon by the network. When the predetermined quantity is achieved through protocol predefinition or network agreement, it can be 2 time slots or 14 symbols, etc.

[0091] Furthermore, if the predetermined quantity is determined based on the terminal's capabilities, the terminal can report the predetermined quantity to the network-side device to ensure communication consistency.

[0092] (27) The sum of the frequency domain resources occupied by the first downlink transmission and the second downlink transmission does not exceed M, M is greater than N, and M is less than or equal to 20MHz.

[0093] The value of M can be determined based on the terminal's capabilities, or it can be predefined by the protocol or implemented by network agreements. Furthermore, when the predetermined quantity is determined based on the terminal's capabilities, the terminal can report the value of M to the network-side device to ensure communication consistency.

[0094] It is worth noting that during downlink transmission, the first and second downlink transmissions scheduled or configured by the network-side equipment should not result in the following situations: the first and second downlink transmissions partially or completely overlap in the time domain but do not overlap in the frequency domain (i.e., located in different PRBs), and the total frequency domain resources used by the first and second downlink transmissions exceed N (e.g., 5MHz). In other words, if the first and second downlink transmissions at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first and second downlink transmissions exceed the bandwidth capacity of the terminal, this can be considered as a result of the network-side equipment performing an incorrect scheduling or configuration behavior. In this case, the terminal may process the first and second downlink transmissions as described in S311 above, or it may not perform any operation, i.e., the terminal behavior is undefined.

[0095] Of course, for the terminal, it is also not desirable for the total frequency domain resources used by the first and second downlink transmissions received to exceed its own bandwidth capacity.

[0096] In this implementation, in addition to enabling the terminal to effectively process multiple received downlink transmissions and thus ensure communication quality, the restrictions on network scheduling are also relaxed. That is, the network can schedule two downlink transmissions so that they partially or completely overlap in the time domain and are located in non-overlapping PRBs in the frequency domain. Furthermore, the total resources used by these two downlink transmissions in the frequency domain can exceed the maximum bandwidth capacity supported by the terminal. This also relaxes the processing complexity of the terminal for two downlink transmissions whose total resources in the frequency domain exceed its maximum bandwidth capacity, prioritizing the demodulation of important transmissions and ensuring communication performance.

[0097] S312, if the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are not greater than the bandwidth capacity of the terminal, the processing method determined by the terminal includes a second processing method, which includes at least one of the following methods 1 to 3.

[0098] Method 1: When the terminal is in an idle or inactive state, the first downlink transmission and the second downlink transmission are decoded, and the first downlink transmission and the second downlink transmission are respectively scheduled by any one of SI-RNTI, P-RNTI, RA-RATI, and TC-RNTI.

[0099] In other words, if the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are not greater than the bandwidth capacity of the terminal, the terminal in the idle or inactive state can (expect or anticipate) decode the first downlink transmission and the second downlink transmission scheduled by any one of SI-RNTI, P-RNTI, RA-RATI, and TC-RNTI.

[0100] Method 2: When the terminal is in a connected state, the first downlink transmission and the second downlink transmission are decoded, wherein the first downlink transmission is scheduled by C-RNTI, MCS-C-RNTI or CS-RNTI, and the second downlink transmission is scheduled by SI-RNTI.

[0101] In other words, if the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are not greater than the bandwidth capacity of the terminal, the terminal in the connected state can (expect, anticipate, or preferentially) decode the first downlink transmission scheduled by C-RNTI, MCS-C-RNTI, or CS-RNTI, and the second downlink transmission scheduled by SI-RNTI.

[0102] Method 3: When the terminal is in a connected state, skip the sixth downlink transmission. The sixth downlink transmission is the downlink transmission scheduled by C-RNTI, MCS-C-RNTI or CS-RNTI in the first downlink transmission and the second downlink transmission, and the processing time of the sixth downlink transmission is required to be less than a third predetermined value.

[0103] In other words, if the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are not greater than the bandwidth capacity of the terminal, then if the processing time of the first downlink transmission and the second downlink transmission scheduled by C-RNTI, MCS-C-RNTI or CS-RNTI is required to be less than a third predetermined value, then the terminal in the connected state skips (does not expect or desire) the downlink transmissions scheduled by C-RNTI, MCS-C-RNTI or CS-RNTI in the first downlink transmission and the second downlink transmission.

[0104] The third predetermined value can be implemented by means of higher-level configuration agreed upon in the protocol. For example, in one implementation, the third predetermined value can be based on the PDSCH second processing capability (PDSCH processingcapability2) specified in TS38.214. This embodiment does not impose specific limitations here.

[0105] It is understood that, for the first downlink transmission and the second downlink transmission mentioned in the foregoing embodiments, as a possible implementation, the first downlink transmission and the second downlink transmission satisfy any one of the following (31)-(35). In other words, the combination of the first downlink transmission and the second downlink transmission can be any one of the following (31)-(35).

[0106] (31) One of the first downlink transmission and the second downlink transmission is a physical downlink shared channel (PDSCH) scheduled by P-RNTI, and the other is a PDSCH scheduled by any one of SI-RNTI, MCCH-RNTI, broadcast group (G)-RNTI, multicast group (G)-RNTI, TC-RNTI, C-RNTI, MCS-C-RNTI, and CS-RNTI;

[0107] (32) One of the first downlink transmission and the second downlink transmission is a PDSCH scheduled by SI-RNTI, and the other is a PDSCH scheduled by any one of P-RNTI, MCCH-RNTI, broadcast G-RNTI, multicast G-RNTI, TC-RNTI, C-RNTI, MCS-C-RNTI, and CS-RNTI.

[0108] (33) One of the first downlink transmission and the second downlink transmission is a PDSCH scheduled by RA-RNTI, and the other is a PDSCH scheduled by any one of SI-RNTI, P-RNTI, MCCH-RNTI, broadcast G-RNTI, and multicast G-RNTI;

[0109] (34) One of the first downlink transmission and the second downlink transmission is a PDSCH scheduled by TC-RNTI, and the other is a PDSCH scheduled by any one of SI-RNTI, P-RNTI, MCCH-RNTI, broadcast G-RNTI, and multicast G-RNTI;

[0110] (35) One of the first downlink transmission and the second downlink transmission is the Physical Broadcast Channel (PBCH), and the other is the PDSCH scheduled by MCCH-RNTI.

[0111] Of course, in the actual downlink transmission process, the combination of the first downlink transmission and the second downlink transmission can be, but is not limited to, the combinations shown in (31)-(35) above, and is not restricted here.

[0112] Furthermore, based on the foregoing description of the downlink transmission method, the implementation process of the downlink transmission provided in this embodiment will be explained below for terminals in different states or modes (such as idle state, inactive state, and connected state) in conjunction with Examples 1 and 2.

[0113] Example 1

[0114] Assuming the terminal is in RRC_IDLE and RRC_INACTIVE modes, the terminal's bandwidth capability N is 5MHz and M is 20MHz, and the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but do not overlap in the frequency domain, then:

[0115] (41) If the total frequency domain resources used by the first downlink transmission and the second downlink transmission are not greater than N = 5MHz (or, for a 15kHz SCS, no more than 25 PRBs, and for a 30kHz SCS, no more than 11 or 12 PRBs), then the terminal can decode the first downlink transmission and the second downlink transmission in mode 1 of S132.

[0116] (42) If the total frequency domain resources used by the first downlink transmission and the second downlink transmission are greater than N = 5MHz (or more than 25 PRBs for 15KHz SCS, and more than 11 or 12 PRBs for 30KHz SCS), then the terminal may process the first downlink transmission and the second downlink transmission in at least one of the methods 1-5 shown in S131.

[0117] The specific implementation process of (41)-(42) can be referred to the relevant descriptions in S131 and S132 above. To avoid repetition, it will not be repeated here.

[0118] Example 2

[0119] Assuming the terminal is in RRC_ACTIVE mode, with a bandwidth capability N of 5MHz and M of 20MHz, the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but not in the frequency domain, and both the first and second downlink transmissions are PDSCH, then, in a cell with frequency range 1, during the SI acquisition process triggered by P-RNTI, then:

[0120] (51) If the total frequency domain resources used by the first downlink transmission and the second downlink transmission are not greater than N = 5MHz (or, for a 15kHz SCS, no more than 25 PRBs, and for a 30kHz SCS, no more than 11 or 12 PRBs), then the terminal may decode the first downlink transmission and the second downlink transmission in accordance with mode 2 and / or mode 3 in S132.

[0121] (52) If the total frequency domain resources used by the first downlink transmission and the second downlink transmission are greater than N = 5MHz (or more than 25 PRBs for 15KHz SCS, and more than 11 or 12 PRBs for 30KHz SCS), then the terminal may process the first downlink transmission and the second downlink transmission in at least one of the methods 1-5 shown in S131.

[0122] The specific implementation process of (51)-(52) can be referred to the relevant descriptions in S131 and S132 above. To avoid repetition, it will not be repeated here.

[0123] It is worth noting that during downlink transmission, if the first downlink transmission and the second downlink transmission overlap at least partially in the time domain but not in the frequency domain, and the total frequency domain resources occupied by the first downlink transmission and the second downlink transmission are not greater than or greater than the bandwidth capacity of the terminal, the terminal may adopt, but is not limited to, the processing methods in Examples 1 and 2 above. This embodiment does not impose any restrictions here.

[0124] Furthermore, for the various implementation methods mentioned in this embodiment, such as the implementation processes involved in the first processing method and the second processing method, the processing method selected by the terminal can be implemented by protocol agreement, high-level configuration or network-side configuration, or it can be determined by the terminal itself and then sent to the network side, thereby ensuring the consistency between the network side and the terminal side, and thus improving the communication quality.

[0125] In this embodiment, when the first downlink transmission and the second downlink transmission at least partially overlap in the time domain but not in the frequency domain, the terminal's behavior is defined by determining the relationship between the total frequency domain resources occupied by the first and second downlink transmissions and the terminal's bandwidth capability. This allows the terminal to effectively process multiple received downlink transmissions, thereby ensuring communication quality. Furthermore, it relaxes network scheduling restrictions, allowing the network to schedule two downlink transmissions that partially or completely overlap in the time domain, are located in non-overlapping frequency bands (PRBs), and whose combined frequency domain resources exceed the terminal's maximum supported bandwidth capability. Simultaneously, it reduces the processing complexity for the terminal dealing with two downlink transmissions whose total frequency domain resources exceed its maximum bandwidth capability, prioritizing the demodulation of important transmissions and ensuring communication performance.

[0131] It is understood that the implementation methods mentioned in method embodiment 400 have the same or corresponding technical features as the implementation methods in the aforementioned method embodiments 200 or 300. Therefore, the implementation process of the implementation methods mentioned in method embodiment 400 can be referred to the relevant descriptions in method embodiments 200 or 300 to achieve the same or corresponding technical effects. To avoid repetition, it will not be described again here.
