[0015] The following briefly describes related art to the embodiments of the present application.
[0016] Machine Type Communications (MTC), also known as Machine to Machine (M2M), is the main application form of IoT. MTC devices deployed in the market are mainly based on the Global System of Mobile communication (GSM) system. Due to the high spectral efficiency of Long Term Evolution (LTE) / LTE-Advanced (LTE-A), more and more mobile communication operators choose LTE / LTE-A as the evolution direction of future broadband wireless communication systems, and the various types of data traffic of MTC based on LTE / LTE-A also become more attractive.
[0017] A Half Duplex-Frequency Division Duplex User Equipment (HD-FDD UE) supports up to 10 Hybrid Automatic Repeat reQuest (HARQ) processes, as shown in FIG. 1.
[0018] As can be seen from FIG. 1, the scheduling delay between MPDCCH and PDSCH is fixed at 2, and the HARQ-ACK feedback delay is as shown in Table 1.
[0019] [Table 1]
[0020] The group of HARQ-ACK delays to be selected is set by higher layer signaling ce-SchedulingEnhancement, and then timing is determined by the control domain of the HARQ-ACK delay in the downlink control information DCI.
[0021] In the Rel-17 MTC system, for half-duplex terminals, the downlink needs to support 14-HARQ processes in order to further increase the downlink peak rate and apply to more scenarios. However, there is no indication method for the PDSCH schedule delay, especially in the scenario where invalid subframes exist.
[0022] As shown in Fig. 2, assuming that the DCI carried by MPDCCH0 indicates that the schedule delay is 7, the UE does not know the unit of the schedule delay value, and therefore cannot determine the subframe in which the corresponding PDSCH0 is located based on the schedule delay value. When the subframe is taken as the unit, PDSCH0 is transmitted in subframe 7 of radio frame h, and since subframe 7 is an invalid downlink subframe, PDSCH0 is transmitted in subframe 8, which is an uplink-downlink switching subframe and PDSCH transmission cannot be performed. When the valid downlink subframe is taken as the unit, PDSCH0 is transmitted in subframe 1 of radio frame h+1, which causes the later PDSCH to be unable to be transmitted or to be postponed to be transmitted, which affects the maximum downlink peak rate.
[0023] Compared with conventional communication systems, new radio access technology (NR) systems have higher configuration flexibility and larger bandwidth range, and correspondingly, the terminal capabilities are also required to be higher, and the terminals need to be more expensive than conventional ones. However, in various scenes supported by NR systems, such high terminal capabilities are not required in all scenes, for example, smart wearable devices, industrial sensors, etc. Therefore, for such scenes, low-spec terminal equipment types such as smaller bandwidth, fewer antennas, half duplex FDD (HD-FDD), relaxed UE processing time, and relaxed UE processing capabilities are defined to reduce the manufacturing cost and complexity of the terminal. Such terminals may be called low-spec terminals or lightweight NR (NR reduced capability, NR RedCap) user terminals.
[0024] For UE processing capability, the standard defines the PDSCH processing time (N1) and the PUSCH preparation time (N2), where: N 1 occupies the major part of the minimum time Tproc,1 between the PDSCH and the corresponding HARQ-ACK, N 2 is the major part of the minimum time Tproc,2 between PDCCH and PUSCH. Depending on the UE capabilities, N 1 / N The two values are different. Tables 2 and 3 correspond to UE processing capability 1. N 1 and N 2. In the case of RedCap UE, the processing time is further reduced, i.e., N 1 / N 2, but does not show the impact on timing in the HARQ process after further relaxing the processing time.

[0068] In one embodiment, the second subframe determined according to the first unit corresponding to the PDSCH schedule delay value includes one downlink valid subframe after the first subframe, one physical subframe, three valid uplink subframes, and a first downlink valid subframe after the one physical subframe, and the second subframe determined according to the second unit corresponding to the PDSCH schedule delay value includes one physical subframe after the first subframe, three valid uplink subframes, and a second downlink valid subframe after the one physical subframe.
[0069] In one exemplary embodiment, a method for implicitly determining a PDSCH scheduling delay is provided.
[0070] The terminal detects an MPDCCH in subframe n, where the DCI indicates that the PDSCH schedule delay value is 7, and the terminal determines a subframe in which the PDSCH transmission is located based on at least one of the following schemes, and the terminal receives the PDSCH:
[0071] Method 1: When the terminal detects an MPDCCH in subframe n+k, the terminal determines the subframe in which the PDSCH transmission is located according to a first unit corresponding to a schedule delay value, where subframe n+k is the first valid downlink subframe after subframe n.
[0072] Method 2: If the terminal does not detect an MPDCCH in subframe n+k, the terminal determines the subframe in which the PDSCH transmission is located according to a second unit corresponding to the schedule delay value, where subframe n+k is the first valid downlink subframe after subframe n.
[0073] Scheme 3: If the number of valid downlink subframes between subframe n and subframe n+r is b1, the terminal determines the subframe in which the PDSCH transmission is located according to a first unit corresponding to the schedule delay value, where subframe n+r is the first downlink-to-uplink conversion subframe after subframe n, and b1 may be 1.
[0074] Scheme 4: If the number of valid downlink subframes between subframe n and subframe n+r is b2, the terminal determines the subframe in which the PDSCH transmission is located according to a second unit corresponding to the schedule delay value, where subframe n+r is the first downlink-to-uplink conversion subframe after subframe n, and b2 may be 0.
[0075] Method 5: When the HARQ process index indicated in the DCI is a first predetermined value (an odd number or a specific process index), the terminal determines the subframe in which the PDSCH transmission is located according to a first unit corresponding to the schedule delay value, and when the HARQ process index indicated in the DCI is a second predetermined value (an even number or another specific process index), the terminal determines the subframe in which the PDSCH transmission is located according to a second unit corresponding to the schedule delay value, and vice versa.
[0076] Scheme 6: When the HARQ-ACK delay value indicated in the DCI is greater than or equal to M, the terminal determines the subframe in which the PDSCH transmission is located according to a first unit corresponding to the schedule delay value; when the HARQ-ACK delay value indicated in the DCI is smaller than M, the terminal determines the subframe in which the PDSCH transmission is located according to a second unit corresponding to the schedule delay value, where M is a preset value or a value set by a higher layer.
[0077] Scheme 7: If the number of valid downlink subframes between subframe n and subframe n+r is greater than or equal to b3, the terminal determines the subframe in which the PDSCH transmission is located according to a first unit corresponding to the schedule delay value, where subframe n+r is the first downlink-to-uplink conversion subframe after subframe n.
[0078] Scheme 8: If the number of valid downlink subframes between subframe n and subframe n+r is less than b3, the terminal determines the subframe in which the PDSCH transmission is located according to a second unit corresponding to the schedule delay value, where subframe n+r is the first downlink-to-uplink conversion subframe after subframe n.
[0079] The first unit corresponding to the schedule delay is one downlink enabled subframe, one physical subframe, three uplink enabled subframes, one physical subframe, and one downlink enabled subframe, and the second unit is one physical subframe, three uplink enabled subframes, one physical subframe, and two downlink enabled subframes.
[0080] The first unit corresponding to the schedule delay means that if the terminal detects the MPDCCH in subframe n, it transmits the PDSCH in one downlink valid subframe, one physical subframe, three valid uplink subframes, and the first downlink valid subframe after the one physical subframe after the subframe. The second unit means that if the terminal detects the MPDCCH in subframe n, it transmits the PDSCH in one physical subframe, three valid uplink subframes, and the second downlink valid subframe after the one physical subframe after the subframe n.
[0081] Alternatively, the first unit corresponding to the schedule delay is two physical subframes, three uplink valid subframes, or two physical subframes, and the second unit is one physical subframe, three uplink valid subframes, or three physical subframes.
[0082] The first unit corresponding to the schedule delay means that if the terminal detects an MPDCCH in subframe n, it transmits a PDSCH in the two physical subframes after subframe n and the second physical subframe after the three valid uplink subframes. The second unit means that if the terminal detects an MPDCCH in subframe n, it transmits a PDSCH in the first physical subframe after subframe n and the third physical subframe after the three valid uplink subframes.
[0083] In one exemplary embodiment, a method is provided for explicitly determining a PDSCH scheduling delay.
[0084] The terminal detects the MPDCCH in subframe n, the terminal determines the subframe in which the PDSCH transmission is located based on the schedule delay value indicated by the DCI, and the terminal receives the PDCCH.
[0085] The PDSCH schedule delay value is indicated by the first signaling domain of 2 bits in the DCI as shown in Table 4.
[0086] [Table 4]
[0087] Wherein, the first signaling domain of 2 bits may be a signaling domain indicating the number of PDSCH repetitions or may be an additional signaling domain, or when configuring a 14-HARQ process, the first signaling domain is 2 bits and the signaling domain indicating the number of PDSCH repetitions is 0 bits.
[0088] In one exemplary embodiment, a method is provided for explicitly determining the HARQ-ACK delay value.
[0089] The terminal receives a PDSCH in subframe m, and determines the subframe in which the HARQ-ACK corresponding to the PDSCH is located based on the HARQ-ACK feedback delay value indicated by the DCI, and transmits the HARQ-ACK according to the PDSCH reception status.
[0090] The HARQ-ACK feedback delay value is determined by k1 indicated by the HARQ-ACK delay indication domain in DCI and k2 indicated by the second signaling domain, i.e., the UE receives a PDSCH in subframe m and sends a HARQ-ACK in subframe m+k1+k2.
[0091] The second signaling domain indicates the number of disabled subframes between the PDSCH and the corresponding HARQ, and the terminal determines the value of k2 based on the uplink / downlink disabled subframe configuration and the value indicated by the second signaling domain, assuming that the second signaling domain is 2 bits, and its meaning is as shown in Table 5.
[0092] [Table 5]
[0093] The second signaling domain may be a signaling domain indicating the number of PDSCH repetitions, or may be an additional signaling domain, or when configuring a 14-HARQ process, the second signaling domain is 2 bits and the signaling domain indicating the number of PDSCH repetitions is 0 bits.
[0094] In a specific embodiment, as shown in FIG. 4, the UE obtains the attribute of the subframe according to the downlink validity indication signaling and the uplink validity indication signaling set by the higher layer, that is, if the value indicated by the downlink validity indication is 1, it is a valid downlink subframe, and if it is 0, it is an invalid downlink subframe, and the meaning of the uplink validity indication is the same. wireless Suppose that PDSCH0 is received in subframe 2 of frame h, and the HARQ-ACK delay indication domain indication k1 in the corresponding DCI is k1=11, and the second signaling domain is 00, and the UE can obtain the invalid subframe configuration, so the UE determines that k2=4, in this case, the UE sends the corresponding HARQ-ACK in subframe 7 of radio frame h+1.
