Embodiments for Carrying Out the Invention

[0019] Detailed Description The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts fall within the protection scope of the present disclosure.

[0020] Terms such as "first", "second", etc. are used only for the purpose of explanation and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the technical features shown. Therefore, the features limited by "first", "second", etc. may explicitly or implicitly include one or more features. In the description of the present disclosure, unless otherwise specified, "a plurality of / many" means two or more.

[0021] In the embodiments of the present disclosure, words such as "exemplary (exemplarily)" or "for example" are used to represent examples, exemplifications, or explanations. The embodiments or design solutions described as "exemplary (exemplarily)" or "for example" in the embodiments of the present disclosure should not be construed as being more preferable or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary (exemplarily)" or "for example" is intended to present related concepts in a specific manner.

[0022] For the RedCap UE in Release 18, when processing the PDSCH corresponding to the random access response (RAR), if the bandwidth of the RAR PDSCH is greater than the maximum bandwidth supported by the Release 18 RedCap UE, the processing waiting time of the Release 18 RedCap UE will increase. For example, the Release 18 RedCap UE has a maximum bandwidth of 20 MHz and a data buffering capacity of 5 MHz for the physical downlink shared channel. Then, when the Release 18 RedCap UE buffers PDSCH data with a bandwidth greater than 5 MHz, it is necessary to process the PDSCH data multiple times, and each process does not exceed the 5 MHz bandwidth of the data. Therefore, when the Release 18 RedCap UE processes a physical channel with a relatively large bandwidth, the processing waiting time becomes relatively large, which may affect the scheduling of uplink physical channels or downlink physical channels that compete in the time domain. Furthermore, the transmission time of the PDSCH for Message 3 (Msg3) scheduled by the RAR will be affected by the waiting time. Alternatively, when another PDSCH is continuously scheduled within a time period, the processing times of the two PDSCHs may overlap with each other, so there is a possibility that the UE cannot process all the PDSCHs.

[0023] In consideration of this, embodiments of the present disclosure provide a physical channel reception method. The physical channel reception method includes that a first communication node first determines a first processing duration, and according to the first processing duration, determines physical channels to be decoded from a first physical channel and a second physical channel, and decodes the physical channels to be decoded. In this way, when the first physical channel and the second physical channel may compete with each other in the time domain, an appropriate physical channel to be decoded is selected from the first physical channel and the second physical channel for decoding, thereby ensuring normal communication of the communication system.

[0024] In addition, embodiments of the present disclosure also provide a physical channel transmission method which includes determining a second processing duration if a first communication node receives a third physical channel and the bandwidth of the third physical channel is greater than the target bandwidth of the first communication node, determining a transmission time for a fourth physical channel according to the second processing duration, and transmitting the fourth physical channel based on the transmission time. Thus, if the bandwidth of the third physical channel is greater than the target bandwidth of the first communication node, a reasonable transmission time for the fourth physical channel is determined based on the second processing duration to avoid the transmission of the fourth physical channel being affected by further processing duration for processing the third physical channel.

[0025] The technical solutions provided in embodiments of this disclosure may be applied to a variety of mobile communication networks, such as New Radio (NR) mobile communication networks using 5th generation mobile networks (5G), future mobile communication networks, or multiple converged communication systems, and are not limited to embodiments of this disclosure.

[0026] The network architecture of a mobile communication network in embodiments of this disclosure (including, but not limited to, 3G, 4G, 5G, and future mobile communication networks) may include network-side devices (including, but not limited to, base stations) and receiving-side devices (including, but not limited to, terminals). Furthermore, in embodiments of this disclosure, the first communication node (also referred to as the first node device) may be a receiving-side device, and the second communication node (also referred to as the second node device) may be a network-side device. Alternatively, the first communication node may be a network-side device, and the second communication node may be a receiving-side device. Further alternatively, in device-to-device communication, both the first and second communication nodes may be terminals or base stations.

[0027] Exemplary, Figure 1 shows a schematic diagram of the structure of a communication system provided in embodiments of the present disclosure. As shown in Figure 1, the communication system 100 may include one or more first communication nodes 11 and a second communication node 12. The second communication node 12 may be communicably connected to one or more first communication nodes 11.

[0028] The first communication node 11 may also be referred to as a terminal device, user equipment, mobile station, or mobile terminal. Exemplary examples of terminals may include mobile phones, tablet computers, computers with wireless transceiver capabilities, virtual reality terminals, augmented reality terminals, wireless terminals for industrial control, wireless terminals for autonomous driving, wireless terminals for remote surgery, wireless terminals for traffic safety, wireless terminals for smart cities, or wireless terminals for smart homes. Embodiments of this disclosure do not limit the device form used for a terminal.

[0029] In embodiments of this disclosure, the first communication node 11 may be a RedCap UE of release 18. That is, the number of PRBs that the first communication node 11 can process for the PDSCH within a slot is less than or equal to the target bandwidth. If the number of PRBs transmitted in the physical channel is greater than the target bandwidth, the processing latency of the RedCap UE of release 18 increases.

[0030] In addition, the second communication node 12 may be used to perform functions such as terminal resource scheduling, radio resource management, and radio access control. For example, the base station may be any one of a small base station, a radio access point, a transmission receive point (TRP), a transmission point (TP), and several other access nodes.

[0031] Figure 1 is merely an illustrative frame diagram, and the number and names of the devices included in Figure 1 are not limited. In addition to the devices shown in Figure 1, the communication system may also include other devices such as core network devices.

[0032] The embodiments of this disclosure do not limit application scenarios. The system architectures and traffic scenarios described in the embodiments of this disclosure are intended to more clearly illustrate the technical solutions of the embodiments of this disclosure and do not limit the technical solutions provided in the embodiments of this disclosure. Those skilled in the art will know that, with the evolution of network architectures and the emergence of new traffic scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0033] Exemplary embodiments of this disclosure provide a physical channel receiving method applicable to a first communication node. As shown in Figure 2, the physical channel receiving method may include the following S101-S103.

[0034] In S101, the first communication node determines the first processing duration.

[0035] The first processing duration is the additional processing duration required for the first type of communication node to process a physical channel larger than the target bandwidth.

[0036] In some embodiments, the target bandwidth may be the number of physical resource blocks (PRBs) in the frequency domain. For example, with a subcarrier interval of 15 kHz, the target bandwidth for a first type of communication node is 25 physical resource blocks. Alternatively, with a subcarrier interval of 30 kHz, the target bandwidth for a first type of communication node is 12 physical resource blocks.

[0037] In some embodiments, the communication node may include a first type of communication node and a second type of communication node.

[0038] In some embodiments, a first type of communication node has at least one of the following characteristics 1 and 2. Therefore, if a first communication node has the following characteristics 1 and / or characteristics 2, it may be determined that the first communication node is a first type of communication node. In addition, if a first communication node does not have characteristics 1 and 2, it may be determined that the first communication node is a second type of communication node.

[0039] Characteristic 1: The first type of communication node satisfies the bandwidth requirement. The bandwidth requirement includes the processing bandwidth of the physical downlink shared channel (PDSCH) being less than or equal to the target bandwidth described above. The processing bandwidth of the PDSCH represents the number of PRBs that the first type of communication node can process for the PDSCH within the slot.

[0040] Bandwidth requirements may also include ensuring that the transmission bandwidth of the physical uplink shared channel (PUSCH) is less than or equal to the target bandwidth described above. The transmission bandwidth of the PUSCH represents the number of PRBs that a first type of communication node can transmit for the PUSCH within a slot or frequency hopping resource.

[0041] Furthermore, since the bandwidth of PDSCH that can be processed or PUSCH that can be transmitted is reduced, the first type of communication node can be less complex.

[0042] Characteristic 2: The first type of communication node meets the peak data rate requirement. The peak data rate requirement includes the product of the number of transmission layers, modulation order, and adjustment factor being less than 4.

[0043] If the product of the number of transmission layers, modulation order, and adjustment factor is less than 4, the peak data rate decreases. It should be understood that the aforementioned peak data rate is determined based on the product of three capability parameters: the number of transmission layers, modulation order, and adjustment factor. Normally, the product of the three capability parameters is 4 or greater. However, the product of the three capability parameters reported by the first type of communication node, namely modulation order, number of transmission layers, and adjustment factor, is less than 4, and the minimum value of the product is equal to 3.2 or 0.8. In the case of the first type of communication node, the product of the three capability parameters is reduced to 3.2 or 0.8, so the peak data rate is reduced accordingly. Furthermore, the first type of communication node has lower complexity.

[0044] In some embodiments, the first processing duration may be determined based on the type of the first communication node.

[0045] In one implementation, the first communication node is a first type of communication node. Furthermore, a first processing duration is determined for the first type of communication node. It should be understood that the first communication node either has characteristic 1 described above, or has characteristic 2 described above, or has both characteristic 1 and characteristic 2 described above.

[0046] In some embodiments, if the first communication node is a first type of communication node, the first processing duration decreases as the subcarrier interval increases.

[0047] For example, with a subcarrier interval of 15 kHz, the first processing duration A is 1 millisecond, which is equal to 14 orthogonal frequency division multiplexing (OFDM) symbols or 1 slot. With a subcarrier interval of 30 kHz, the first processing duration A is 0.5 milliseconds, which is equal to 14 OFDM symbols or 1 slot.

[0048] In another example, for a subcarrier interval of 15 kHz, the first processing duration A is 0.5 milliseconds, or equal to 7 OFDM symbols. For a subcarrier interval of 30 kHz, the first processing duration A is 0.25 milliseconds, or equal to 7 OFDM symbols.

[0049] In another implementation, the first communication node is a second type of communication node, and the first processing duration is 0 milliseconds.

[0050] In the case of the second type of communication node, it should be noted that the processing bandwidth of the physical downlink shared channel and the transmission bandwidth of the physical uplink shared channel are greater than the target bandwidth. The first processing duration can be understood as the additional processing duration required for the first type of communication node to process physical channels that are larger than the target bandwidth. In the case of the first type of communication node, the processing bandwidth of the PDSCH is small and the processing bandwidth of a single PDSCH is limited, so PDSCHs larger than the target bandwidth must be processed multiple times, resulting in additional processing duration, i.e., the first processing duration described above. On the other hand, in the case of the second type of communication node, the processing bandwidth of the PDSCH is not limited and no additional processing duration is generated, so the first processing duration A is equal to 0.

[0051] In S102, the first communication node determines the physical channel to be decoded from the first physical channel and the second physical channel according to the first processing duration.

[0052] In some embodiments, the first physical channel and the second physical channel compete with each other in the time domain. Therefore, the first communication node may determine which physical channel should be decoded from the first physical channel and the second physical channel.

[0053] Note that since the single processing bandwidth of a physical channel of the first type of communication node is limited, physical channels with a bandwidth greater than the target bandwidth of the first type of communication node require additional processing duration. If two physical channels are scheduled consecutively within a given time window, and the transmission bandwidth of the first physical channel is greater than the target bandwidth, the processing times of the two physical channels will overlap due to the longer processing duration of the first physical channel; that is, the processing times of the two physical channels will compete with each other in the time domain. Therefore, the first communication node may determine the decoding priority of the physical channels and prioritize decoding one of the two physical channels.

[0054] In some embodiments, the first or second physical channel may be a physical uplink shared channel, a physical downlink shared channel, or other physical channels, not limited to these.

[0055] In some embodiments, the first communication node may determine which physical channel to decode from the first and second physical channels according to a first processing duration. Exemplarily, at least three decision modes exist.

[0056] Decision Mode 1: If the transmission time period of the second physical channel overlaps with the time period of the first processing duration after the transmission end time domain symbol of the first physical channel, the first communication node can determine that there is a conflict between the first and second physical channels in the time domain, and then the first communication node determines which physical channels should be decoded from the first and second physical channels. The transmission end time domain symbol of the first physical channel can be understood as the last OFDM symbol of the transmitted first physical channel, i.e., the transmission end point of the first physical channel.

[0057] In other words, the transmission time period of the second physical channel from the start to the end of transmission can be determined. A time range can also be determined, where the start time is the first OFDM symbol after the end of transmission on the first physical channel, and the duration is the first processing duration. If the transmission time period of the second physical channel partially or completely overlaps with the time range, the first communication node can determine that there is a conflict between the first physical channel and the second physical channel in the time domain.

[0058] Decision Mode 2: When the first physical channel is transmitted in slot n and the second physical channel is transmitted in slot n+k, the first communication node can determine that there is a conflict between the first and second physical channels in the time domain, and then the first communication node determines which physical channel should be decoded from the first and second physical channels. k is less than or equal to the first processing duration. Exemplary, when the first physical channel is transmitted in slot n and the second physical channel is transmitted in slot n+A, the physical channel to be decoded is determined from the first and second physical channels. A is the first processing duration described above. In addition, the first processing duration is equal to one slot, i.e., A=1.

[0059] Decision Mode 3: If the transmission time of the second physical channel partially or completely overlaps with the first time window, the first communication node determines the physical channels to be decoded from the first and second physical channels. The start of the first time window described above is the start OFDM symbol of the first physical channel, and the end of the first time window is the point determined by adding the end OFDM symbol of the first physical channel to the first processing duration.

[0060] In some embodiments, the multiple physical channels described above may or may not come from the same transmitting end.

[0061] In some embodiments, a first communication node can obtain scheduling information for a first physical channel and a second physical channel. The scheduling information includes at least one of the time-domain location, bandwidth, and channel type of the physical channel.

[0062] In some embodiments, the time-domain location of a physical channel can be understood as the time-domain symbol occupied by the physical channel in the time domain. For example, the time-domain location of a physical channel may indicate the start time-domain symbol and duration of the physical channel.

[0063] In some embodiments, time-domain symbols may be orthogonal frequency division multiplexing (OFDM) symbols.

[0064] In some embodiments, the channel type includes at least one of a System Information Block (SIB), a terminal-specific physical shared channel, a physical shared channel for paging, Message 4 (Msg4), and a Random Access Response (RAR).

[0065] In some embodiments, the physical channel to be decrypted may be understood as the physical channel that should be given priority for decryption among the first and second physical channels. In other words, the physical channel to be decrypted may be understood as the physical channel that is decrypted first among the first and second physical channels.

[0066] In some embodiments, the first communication node may determine which physical channel to decode from among multiple physical channels, and as a result, there may be one or more physical channels to decode, and not limited to them.

[0067] In some embodiments, if there is a physical channel among the first and second physical channels that should not be decrypted, the first communication node may abandon the physical channel that should not be decrypted. Alternatively, the first communication node may decrypt the physical channel that should be decrypted after it has been completely decrypted.

[0068] In some embodiments, the first communication node may have the following four decoding schemes.

[0069] Method 1: The first communication node can first decode the first physical channel, and then decode the second physical channel.

[0070] Method 2: The first communication node can first decode the second physical channel, and then decode the first physical channel.

[0071] Method 3: The first communication node can decode the first physical channel and abandon the decoding of the second physical channel.

[0072] Method 4: The first communication node can decode the second physical channel and abandon the decoding of the first physical channel.

[0073] In embodiments of this disclosure, the physical channel is scheduled by a Radio Network Temporary Identifier (RNTI). Taking PDSCH as an example, PDSCH can be scheduled by Random Access RNTI (RA-RNTI), Cell RNTI (C-RNTI), Modulation Coding Scheme Cell RNTI (MCS-C-RNTI), Semi-Persistence Scheduling RNTI (SPS-RNTI), Configured Scheduling RNTI (CS-RNTI), Group RNTI (G-RNTI), Multicast Broadcast Service Control Channel RNTI (MCCH-RNTI), and Group Configured Scheduling This may include PDSCH scheduled by RNTI (G-CS-RNTI), PDSCH scheduled by Message B Radio Network Temporary Identifier (Message B RNTI, MsgB-RNTI), or PDSCH scheduled by System Information Radio Network Temporary Identifier (System information RNTI, SI-RNTI).

[0074] The following provides an illustrative example of an implementation in which the first communication node determines the physical channel to be decoded, considering different cases of wireless network temporary identifiers for the first and second physical channels.

[0075] In one example, the first physical channel may include a physical downlink shared channel (PDSCH) scheduled by RA-RNTI or MsgB-RNTI, and the second physical channel may include a PDSCH scheduled by C-RNTI, MCS-C-RNTI, CS-RNTI, SPS-RNTI, G-RNTI, MCCH-RNTI, or G-CS-RNTI, and therefore the first communication node may determine the first physical channel as the physical channel to be decoded.

[0076] In another example, the first physical channel includes a PDSCH triggered by a Paging Radio Network Temporary Identifier (P-RNTI) and scheduled by a System Information Radio Network Temporary Identifier (SI-RNTI), and the second physical channel includes a PDSCH scheduled by a C-RNTI, MCS-C-RNTI, SPS-RNTI, or CS-RNTI, and therefore the first communication node may determine the first physical channel as the physical channel to be decoded.

[0077] In yet another example, the first physical channel may include a PDSCH corresponding to system information if system information is automatically acquired, and the second physical channel may include a PDSCH scheduled by C-RNTI, MCS-C-RNTI, SPS-RNTI, or CS-RNTI, and therefore the first communication node may determine the second physical channel as the physical channel to be decoded.

[0078] In yet another example, the first physical channel includes a broadcast PDSCH scheduled by G-RNTI, a multicast PDSCH scheduled by G-RNTI, a PDSCH scheduled by MCCH-RNTI, or a PDSCH scheduled by G-CS-RNTI, and the second physical channel includes a PDSCH scheduled by C-RNTI, CS-RNTI, or SPS-RNTI, and therefore the first communication node may determine the second physical channel as the physical channel to be decoded, or the first physical channel as the physical channel to be decoded.

[0079] In yet another example, the first physical channel includes a PDSCH scheduled by RA-RNTI, SI-RNTI, or MsgB-RNTI, and the second physical channel includes a physical downlink control channel (PDCCH) or a physical broadcast channel (PBCH). Thus, the first communication node may determine the second physical channel to be decoded, or the first physical channel to be decoded.

[0080] In S103, the first communication node decodes the physical channel to be decoded.

[0081] Decoding is the reverse process of encoding. A first communication node can obtain the decoded result by performing channel decoding on the physical channel to be decoded, based on the encoding mode used by the transmitting node that transmits the physical channel to be decoded. In addition, the first communication node has a decoder and performs a decoding operation on the channel to be decoded based on the decoder.

[0082] Based on the above embodiment, the RedCap UE of Release 18 has high processing latency when processing physical channels with high bandwidth, so the first and second physical channels may compete with each other in the time domain, and the first communication node cannot decode the first and second physical channels simultaneously. Therefore, the first communication node can select the appropriate physical channel to be decoded from the first and second physical channels and decode the physical channel to ensure that the first communication node can obtain important information carried by the physical channel to be decoded in a timely manner, thereby ensuring normal communication of the communication system.

[0083] In some embodiments, the disclosure further provides a physical channel transmission method which may be applicable to a first communication node. As shown in Figure 3, the method includes the following S201-S204.

[0084] In S201, the first communication node receives the third physical channel.

[0085] In some embodiments, the bandwidth of the third physical channel is greater than the target bandwidth of the first communication node.

[0086] The target bandwidth can be the number of physical resource blocks in the frequency domain. For example, with a subcarrier spacing of 15 kHz, the target bandwidth is 25 physical resource blocks. Alternatively, with a subcarrier spacing of 30 kHz, the target bandwidth is 12 physical resource blocks.

[0087] In S202, if the bandwidth of the third physical channel is greater than the target bandwidth, the first communication node determines the second processing duration.

[0088] A bandwidth of the third physical channel greater than the target bandwidth indicates that the number of PRBs used to transmit through the third physical channel is greater than the target bandwidth.

[0089] The second processing duration is the additional processing duration required for the first type of communication node to process a physical channel larger than the target bandwidth.

[0090] In some embodiments, the first communication node may determine a second processing duration based on the type of the first communication node.

[0091] Since the single processing bandwidth of a PDSCH in the first type of communication node is limited, PDSCHs with a bandwidth larger than the target bandwidth must be processed multiple times, and therefore require additional processing time, i.e., the second processing duration described above.

[0092] The communication nodes may include a first type of communication node and a second type of communication node. The first and second types of communication nodes may be referred to in the relevant description in S101 above, which will not be repeated here.

[0093] In one implementation, the first communication node is a first type of communication node. Furthermore, the second processing duration may be determined based on the first type of communication node, and the second processing duration decreases as the subcarrier interval increases.

[0094] For example, with a 15kHz subcarrier interval, the second processing duration may be equal to 1 millisecond, or it may be represented by 14 OFDM symbols or 1 slot. With a 30kHz subcarrier interval, the second processing duration may be equal to 0.5 milliseconds, or it may be represented by 14 OFDM symbols or 1 slot.

[0095] In another example, for a 15 kHz subcarrier interval, the second processing duration is equal to 0.5 milliseconds, or it may be represented as 7 OFDM symbols. For a 30 kHz subcarrier interval, the second processing duration is equal to 0.25 milliseconds, or it may be represented as 7 OFDM symbols.

[0096] In another possible implementation, the first communication node is a second type of communication node, and the second processing duration is 0 milliseconds.

[0097] In some embodiments, the second processing duration value differs between a separate initial bandwidth part (BWP) corresponding to the RedCap UE and the initial BWP where Control Resource Set 0 (CORESET#0) is located.

[0098] In some embodiments, the bandwidth of the fourth physical channel is also greater than the target bandwidth.

[0099] In S203, the first communication node determines the transmission time of the fourth physical channel according to the second processing duration.

[0100] In some embodiments, the transmission time of the fourth physical channel may be determined based on the second processing duration and transmission time of the third physical channel.

[0101] In some embodiments, the first communication node may determine the transmission time of the fourth physical channel based on at least the following four implementations.

[0102] Implementation form 1: The minimum time interval between the transmission end time domain symbol of the third physical channel and the transmission start time domain symbol of the fourth physical channel is equal to the sum of the preset physical downlink shared channel processing duration, the preset physical uplink shared channel preparation duration, the second processing duration, and the first preset duration.

[0103] In embodiments of the present disclosure, the transmission end time-domain symbol of the third physical channel may be understood as the last OFDM symbol received by the first communication node on the third physical channel, and the reception time of the third physical channel may then be determined based on the OFDM symbol. The transmission start time-domain symbol of the fourth physical channel may be understood as the first OFDM symbol of the transmitted fourth physical channel, and the time for transmitting the OFDM symbol is the transmission time of the fourth physical channel.

[0104] For example, the minimum time interval is equal to A2 + B + C + D1, where A2 is the second processing duration, B is the pre-configured physical downlink shared channel processing duration, C is the pre-configured physical uplink shared channel preparation duration, and D1 is the first pre-configured duration, which may be 0.5 milliseconds.

[0105] In this implementation, the third physical channel is a physical downlink shared channel corresponding to the random access response, and the fourth physical channel is a physical uplink shared channel corresponding to message 3 (Msg3). The first communication node successfully receives the random access response and should be understood to be based on a Type 1 random access procedure (i.e., a 4-step random access process).

[0106] Implementation form 2: The time interval between the transmission end time domain symbol of the third physical channel and the transmission start time domain symbol of the fourth physical channel is greater than or equal to the sum of the pre-set physical downlink shared channel processing duration, the second processing duration, and the first pre-set duration.

[0107] For example, the minimum time interval is equal to A2 + B + D1, where A2 is the second processing duration, B is the pre-configured physical downlink shared channel processing duration, and D1 is the first pre-configured duration, which may be 0.5 milliseconds.

[0108] In this implementation, the third physical channel is a physical downlink shared channel corresponding to the random access response, and the fourth physical channel is a physical uplink control channel that carries the acknowledgment (ACK) information for the correct decoding of the third physical channel. The first communication node successfully receives the random access response and should be understood to be based on a type 2 random access procedure (i.e., a two-step random access process).

[0109] Implementation form 3: If the first communication node fails to correctly decode the third physical channel, or if the third physical channel does not contain a Random Access Preamble Identifier (RAPID) corresponding to the first communication node, the time interval between the transmission time of the fourth physical channel and the transmission end time region symbol of the third physical channel is less than or equal to the sum of the second processing duration, the pre-configured physical downlink shared channel processing duration, and the second pre-configured duration.

[0110] The transmission end time domain symbol for the third physical channel can be understood as the last OFDM symbol at which the first communication node receives the third physical channel, and the reception time for the third physical channel can then be determined based on the OFDM symbol.

[0111] For example, the minimum time interval is equal to A2 + B + D2, where A2 is the second processing duration, B is the pre-configured physical downlink shared channel processing duration, and D2 is the second pre-configured duration, which may be 0.75 milliseconds.

[0112] In some embodiments, upper-layer signaling instructs the first communication node to send PRACH.

[0113] In this implementation, the third physical channel is a PDSCH corresponding to RAR, and the fourth physical channel is a Physical Random Access Channel (PRACH). The first communication node does not receive the third physical channel properly and should be understood to be based on a Type 2 random access procedure (i.e., a 4-step random access process).

[0114] Implementation form 4: If the first communication node fails to correctly decode the third physical channel, or if the third physical channel does not contain a Random Access Preamble Identifier (RAPID) corresponding to the first communication node, the time interval between the transmission time of the fourth physical channel and the final time-domain symbol of the received third physical channel is less than or equal to the sum of the second processing duration, the pre-configured physical downlink shared channel processing duration, and the second pre-configured duration.

[0115] The transmission end time domain symbol for the third physical channel can be understood as the last OFDM symbol at which the first communication node receives the third physical channel, and the reception time for the third physical channel can then be determined based on the OFDM symbol.

[0116] For example, the minimum time interval is equal to A2 + B + D2, where A2 is the second processing duration, B is the pre-configured physical downlink shared channel processing duration, and D2 is the second pre-configured duration, which may be 0.75 milliseconds.

[0117] In some embodiments, upper-layer signaling instructs a first communication node to send PRACH based on a Type 1 random access procedure, or to send PRACH and PUSCH based on a Send Type 2 random access procedure.

[0118] In this implementation, the third physical channel is the physical downlink shared channel corresponding to the Message B Radio Network Temporary Identifier (MsgB-RNTI), and the fourth physical channel is the physical random access channel (PRACH).

[0119] In some embodiments, the values ​​of the second processing duration may be the same or different in the four implementations described above. In some embodiments, at least two of the four implementations described above have different values ​​for the second processing duration.

[0120] In some embodiments, time-domain symbols may be orthogonal frequency-division multiplexing (OFDM) symbols.

[0121] In S204, the first communication node transmits the fourth physical channel based on the determined transmission time.

[0122] Based on the above embodiment, if the bandwidth of the third physical channel is greater than the target bandwidth of the first communication node, the reasonable transmission time of the fourth physical channel is determined based on the second processing duration in order to avoid conflicts between processing of the third physical channel and transmission of the fourth physical channel.

[0123] This disclosure further provides a method for determining the characteristics of a first communication node. The determination method may be applicable to a second communication node and the first communication node. As shown in Figure 4, the method includes the following S301 and S302.

[0124] In S301, the second communication node receives the number of transmission layers, modulation order, and adjustment coefficient transmitted by the first communication node.

[0125] The first communication node can transmit the number of transmission layers, the modulation order, and the adjustment coefficient to the second communication node. The second communication node then receives the number of transmission layers, the modulation order, and the adjustment coefficient.

[0126] The number of transmission layers is the maximum number of transmission layers supported by the PDSCH or PUSCH transmission of the first communication node. For example, in the case of PDSCH, the first communication node supports a maximum of 2 layers of transmission, and the number of transmission layers for transmission is 2.

[0127] The modulation order is the modulation order used to calculate the peak data rate of the first communication node. The first communication node transmits the modulation order according to its own capabilities. If the transmitted modulation order corresponds to M, the second communication node can calculate the peak data rate supported by the first communication node based on the modulation order M, where M may be equal to 1, 2, 4, 6, or 8.

[0128] The adjustment factor is an adjustment factor used to calculate the peak data rate of the first communication node. For example, the adjustment factor may be a value of 0.4, 0.75, 0.8, or 1. In some embodiments, the adjustment factor may take other values, but is not limited to them. The first communication node transmits the adjustment factor according to its own capabilities.

[0129] In some embodiments, the peak data rate of the first communication node is calculated based on the product of the number of transmission layers, the modulation order, and the adjustment coefficient. The peak data rate of the first communication node increases monotonically with the product of the three parameters described above. The higher the product of the number of transmission layers, the modulation order, and the adjustment coefficient, the higher the peak data rate.

[0130] In S302, the second communication node determines the characteristics possessed by the first communication node according to the product of the number of transmission layers, the modulation order, and the adjustment coefficient.

[0131] The communication node may include a first type of communication node and a second type of communication node. The first communication node has at least one of the following two characteristics:

[0132] Characteristic 1: The first type of communication node satisfies the bandwidth requirement. The bandwidth requirement includes the processing bandwidth of the PDSCH being less than or equal to the target bandwidth described above. The processing bandwidth of the PDSCH represents the number of PRBs that the first type of communication node can process for the PDSCH within a slot.

[0133] Bandwidth requirements may include ensuring that the transmission bandwidth of the PUSCH is less than or equal to the target bandwidth described above. The transmission bandwidth of the PUSCH represents the number of PRBs that a first type of communication node can transmit for the PUSCH within a slot or frequency-hopping resource.

[0134] Characteristic 2: The first type of communication node meets the peak data rate requirement. The peak data rate requirement includes the product of the number of transmission layers, modulation order, and adjustment factor being less than 4.

[0135] If the product of the number of transmission layers, modulation order, and adjustment factor is less than 4, the peak data rate decreases. It should be understood that the aforementioned peak data rate is determined based on the product of three capability parameters: the number of transmission layers, modulation order, and adjustment factor. Normally, the product of the three capability parameters is 4 or greater. However, the product of the three capability parameters reported by the first type of communication node, namely modulation order, number of transmission layers, and adjustment factor, is less than 4, and the minimum value of the product is equal to 3.2 or 0.8. For the first type of communication node, the product of the three capability parameters is reduced to 3.2 or 0.8, thereby reducing the peak data rate accordingly. Furthermore, the first type of communication node has lower complexity.

[0136] It should be understood that the first communication node may have characteristic 1 above, or characteristic 2 above, or both characteristic 1 and characteristic 2 above. The second communication node determines the characteristics possessed by the first communication node according to the number of transmission layers, modulation order, and adjustment coefficient reported by the first communication node.

[0137] In some embodiments, when the product of the number of transmission layers, the modulation order, and the adjustment coefficient is less than 3.2, the first type of communication node has characteristic 2 above, but does not have characteristic 1 above.

[0138] In some embodiments, when the product of the number of transmission layers, the modulation order, and the adjustment coefficient is 3.2 or greater and less than 4, the first type of communication node has the above characteristics 1 and 2.

[0183] In the technical solutions provided in the embodiments of this disclosure, since RedCap UE release 18 has high processing latency when processing physical channels with high bandwidth, the first and second physical channels may compete with each other in the time domain, and the first communication node cannot decode the first and second physical channels simultaneously. Therefore, the first communication node can select the appropriate physical channel to be decoded from the first and second physical channels and decode the physical channel to ensure that the first communication node can obtain important information carried by the physical channel to be decoded in a timely manner, thereby ensuring normal communication of the communication system. In addition, if the bandwidth of the third physical channel is greater than the target bandwidth of the first communication node, a reasonable transmission time for the fourth physical channel is determined based on the second processing duration to avoid competition between processing of the third physical channel and transmission of the fourth physical channel.
