Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a determination method, a sending method, a terminal device and a network device. Background Art

[0002] In the prior art, in order to save the control signaling overhead of the network, in addition to dynamic scheduling, the NR (New Radio) R15 standard also provides a semi-persistent scheduling (Semi-Persistent Scheduling, referred to as SPS) method, which allows network equipment (for example, base stations) to perform SPS configuration on users through high-level signaling, and activate it through the downlink control information (Downlink Control Information, referred to as DCI) of the physical layer, so as to achieve the purpose of periodically allocating wireless resources to specific users. It can be seen that semi-persistent scheduling has the characteristics of "one scheduling, multiple uses".

[0003] R15 SPS is mainly aimed at Voice over Internet Protocol (VoIP) services. The minimum period of SPS supports 10ms, and only one activated SPS configuration is supported on a BWP (bandwidth Part). In order to use SPS to support Industrial Internet of Things (IIoT) services, the R16 standard enhances SPS in two directions: on the one hand, it supports multiple simultaneously activated SPS configurations on a BWP, and on the other hand, it shortens the SPS period from the minimum 10ms of Rel 15 to the shortest 1 slot of Rel 16.

[0004] At present, there are IIoT with irregular periods. Regardless of whether it is the above-mentioned SPS configuration method that supports multiple simultaneous activations or a SPS configuration with a smaller period, there will be an activated SPS PDSCH (Physical Downlink Shared Channel) when there is no data packet transmission. In this case, the terminal device does not know that the network device has no downlink data packet, and it will still receive the SPS PDSCH or report HARQ-ACK (Hybrid automatic repeat request acknowledgement) for the SPS PDSCH, which will cause energy waste of the terminal device.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In an embodiment of the present invention, a determination method, a repeated transmission control method and related equipment are proposed to solve the problem that in the existing repeated transmission scheme, the transmitting end cannot distinguish the number of times the target receiving end correctly demodulates the physical channel, making it difficult to reasonably adjust the number of repeated transmissions of subsequent physical channels, which easily causes a waste of physical resources.

[0048] See also Figure 1 , Figure 1 is a flow chart of a determination method provided by an embodiment of the present invention, which is used in a terminal device, such as Figure 1 As shown, the method comprises the following steps:

[0049] Step S101: according to the first indication information or the first rule, determine to receive or mediate the first physical downlink shared channel PDSCH or the first PDSCH group, and / or generate or report a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group; or,

[0050] like Figure 2 As shown, the method comprises the following steps:

[0051] Step S201: According to the first indication information or the first rule, determine not to receive or modulate the first physical downlink shared channel PDSCH or the first PDSCH group, and / or do not generate or report a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group;

[0052] Among them, the first PDSCH is a PDSCH without a corresponding physical downlink control channel PDCCH transmission, and the first PDSCH group includes at least two PDSCHs without a corresponding physical downlink control channel PDCCH transmission. The above-mentioned first physical downlink shared channel PDSCH is the first PDSCH, a PDSCH without a corresponding physical downlink control channel PDCCH transmission. It should be noted that the first PDSCH can also be a candidate PDSCH reception opportunity, and the first PDSCH group can also include at least two candidate PDSCH reception opportunities.

[0053] The first indication information may be indication information sent by a network device (e.g., a base station) to a terminal device, and may be used to indicate receiving or modulating a first PDSCH or a first PDSCH group, and / or generating or reporting a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, or to indicate not receiving or modulating the first PDSCH or the first PDSCH group, and / or not generating or reporting a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group. In this embodiment, the terminal device may determine to receive or modulate the first PDSCH or the first PDSCH group, and / or generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, according to the first indication information or the first rule, or determine not to receive or modulate the first PDSCH or the first PDSCH group, and / or not generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, according to the first indication information or the first rule.

[0054] For example, the first indication information may indicate receiving the first PDSCH or the first PDSCH group, and the terminal device may determine to receive the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate demodulating the first PDSCH or the first PDSCH group, and the terminal device may determine to demodulate the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate generating a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, and the terminal device may determine to generate a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate reporting (for example, reporting to a network device, i.e., sending to a network device) a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, and the terminal device may determine to report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first indication information.

[0055] For another example, the first indication information may indicate that the first PDSCH or the first PDSCH group is not received, and the terminal device may determine not to receive the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate that the first PDSCH or the first PDSCH group is not demodulated, and the terminal device may determine not to demodulate the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate that a hybrid automatic repeat request response HARQ-ACK is not generated for the first PDSCH or the first PDSCH group, and the terminal device may determine not to generate a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first indication information. The first indication information may also indicate that a hybrid automatic repeat request response HARQ-ACK is not reported for the first PDSCH or the first PDSCH group, and the terminal device may determine not to report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first indication information.

[0056] Among them, the first rule can be understood as a first rule based on a reference signal, and the reference signal is received by the terminal device from the network device. As an example, the reference signal may include a second reference signal and at least one item in a second reference signal group as well as the first reference signal.

[0057] In the determination method of this embodiment, the first PDSCH is a PDSCH without a corresponding physical downlink control channel PDCCH transmission, and the first PDSCH group includes at least two PDSCHs without a corresponding physical downlink control channel PDCCH transmission. Through the first indication information or the first rule, it can be determined to receive or modulate the first physical downlink shared channel PDSCH or the first PDSCH group, and / or generate or report a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group; or, it can be determined not to receive or modulate the first physical downlink shared channel PDSCH or the first PDSCH group, and / or not to generate or report a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group. In the method of this embodiment, not all PDSCHs are received or demodulated, and / or HARQ-ACK is reported, but the terminal device needs to determine, based on the first indication information or the first rule, to receive or modulate the first PDSCH or the first PDSCH group without the corresponding physical downlink control channel PDCCH transmission, and / or generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group; or, determine not to receive or modulate the first PDSCH or the first PDSCH group without the corresponding physical downlink control channel PDCCH transmission, and / or not generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, so that the PDSCH that needs to be received or demodulated is received or demodulated, and the first PDSCH or the first PDSCH group that needs to generate or report HARQ-ACK is generated or reported, so that the energy consumption of the terminal device can be reduced. At the same time, the transmission reliability of PUCCH (Physical Uplink Control Channel) can be improved.

[0058] Optionally, according to a first rule, determining to receive or modulate a first PDSCH or a first PDSCH group, and / or generating or reporting a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group;

[0059] The first rule includes at least one of the following:

[0061] A ratio of the RSRP or RSRQ or RSSI or SINR of the first reference signal to an average value or a weighted value of the RSRP or RSRQ or RSSI or SINR of the second reference signal group is greater than or equal to a first threshold;

[0062] A difference between RSRP, RSRQ, RSSI, or SINR of the first reference signal and the second reference signal is greater than or equal to a second threshold;

[0063] A difference between the RSRP or RSRQ or RSSI or SINR of the first reference signal and an average value or a weighted value of the RSRP or RSRQ or RSSI or SINR of the second reference signal group is greater than or equal to a second threshold.

[0064] In this embodiment, the terminal device determines to receive or mediate the first PDSCH or the first PDSCH group, and / or generates or reports a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first rule. The first rule is related to the reference signal, specifically to the RSRP or RSRQ or RSSI or SINR of the reference signal. RSRP is full spelling of Reference Signal Received Power, and its Chinese name is reference signal received power. RSRQ is full spelling of Reference Signal Received Quality, and its Chinese name is reference signal received quality. RSSI is full spelling of Received Signal Strength Indication, and its Chinese name is received signal strength indication. SINR is full spelling of Signal to Interference plus Noise Ratio, and its Chinese name is signal to interference plus noise ratio.

[0065] As long as the first rule includes at least one of the above four items, it means that the conditions for receiving or modulating the first PDSCH or the first PDSCH group, and / or generating or reporting the hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group are met. Then, it can be determined to receive or modulate the first PDSCH or the first PDSCH group, and / or generate or report the hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group, that is, to receive or modulate the first PDSCH or the first PDSCH group that meets the first rule, and / or report HARQ-ACK, thereby reducing energy consumption and improving PUCCH transmission reliability.

[0067] Taking the example of an item in which the difference between the RSRP or RSRQ or RSSI or SINR of the first reference signal and the second reference signal is greater than or greater than or equal to the second threshold, when the first rule includes this item, it can be determined that the first PDSCH or the first PDSCH group is received or mediated, and / or a hybrid automatic repeat request response HARQ-AC is generated or reported for the first PDSCH or the first PDSCH group, wherein the difference being greater than or greater than or equal to the second threshold can be understood as the difference being greater than the second threshold, or the difference being greater than or equal to (≥) the second threshold.

[0068] It should be noted that the ratio of the RSRP or RSRQ or RSSI or SINR of the first reference signal to the average value or weighted value of the RSRP or RSRQ or RSSI or SINR of the second reference signal group can be understood as the ratio of the RSRP of the first reference signal to the average value or weighted value of the RSRP of the second reference signal group, the ratio of the RSRQ of the first reference signal to the average value or weighted value of the RSRQ of the second reference signal group, the ratio of the RSSI of the first reference signal to the average value or weighted value of the RSSI of the second reference signal group, or the ratio of the SINR of the first reference signal to the average value or weighted value of the SINR of the second reference signal group. The difference between the average value or weighted value of RSRP or RSRQ or RSSI or SINR of the first reference signal and the RSRP or RSRQ or RSSI or SINR of the second reference signal group is greater than or equal to the second threshold value, which can be understood as the difference between the average value or weighted value of RSRP of the first reference signal and the RSRP of the second reference signal group, the difference between the average value or weighted value of RSRQ of the first reference signal and the RSRQ of the second reference signal group, the difference between the average value or weighted value of RSSI of the first reference signal and the RSSI of the second reference signal group, or the difference between the average value or weighted value of SINR of the first reference signal and the SINR of the second reference signal group.

[0069] Optionally, according to the first rule, determining not to receive or modulate the first PDSCH or the first PDSCH group, and / or not to generate or report a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group;

[0075] That is, in this embodiment, the terminal device determines not to receive or modulate the first PDSCH or the first PDSCH group, and / or not to generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first rule. As long as the first rule includes at least one of the above four items, it means that the conditions for receiving or modulating the first PDSCH or the first PDSCH group, and / or generating or reporting a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group are not met, and it can be determined not to receive or modulate the first PDSCH or the first PDSCH group, and / or not generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group. That is, the first PDSCH or the first PDSCH group that does not meet the first rule is not received or modulated, and / or HARQ-ACK is not reported, thereby reducing energy consumption and improving PUCCH transmission reliability.

[0076] Taking the example that the ratio of the reference signal received power RSRP or the reference signal received quality RSRQ or the received signal strength indication RSSI or the signal to interference plus noise ratio SINR of the first reference signal to the second reference signal is less than or less than or equal to the first threshold, when the first rule includes this item, it can be determined that the first PDSCH or the first PDSCH group is not received or modulated, and / or the hybrid automatic repeat request acknowledgement HARQ-ACK is not generated or reported for the first PDSCH or the first PDSCH group, wherein the ratio is less than or less than or equal to the first threshold can be understood as the ratio can be less than the first threshold, or the ratio can be less than or equal to (≤) the first threshold.

[0077] Taking the example of an item in which the difference between the RSRP or RSRQ or RSSI or SINR of the first reference signal and the second reference signal is less than or less than or equal to the second threshold, when the first rule includes this item, it can be determined that the first PDSCH or the first PDSCH group is not received or modulated, and / or the hybrid automatic repeat request acknowledgement HARQ-ACK is not generated or reported for the first PDSCH or the first PDSCH group, wherein the difference being less than or less than or equal to the second threshold can be understood as the difference being less than the second threshold, or the difference being less than or equal to (≤) the second threshold.

[0078] Optionally, according to a first rule, determining to receive or modulate a first PDSCH or a first PDSCH group, and / or generating or reporting a hybrid automatic repeat request acknowledgment HARQ-ACK for the first PDSCH or the first PDSCH group;

[0079] The first rule includes at least one of the following:

[0084] In this embodiment, the terminal device determines to receive or modulate the first PDSCH or the first PDSCH group, and / or to generate or report a hybrid automatic repeat request response HARQ-ACK for the first PDSCH or the first PDSCH group according to the first rule.

[0132] Receiving first indication information configured by the network device through high-layer signaling;

[0133] A plurality of candidate first indication information is received and configured by a network device through high-layer signaling; and a second DCI is received and sent by the network device, where the second DCI is used to indicate that the first indication information is one of the plurality of candidate first indication information.

[0134] That is, in this embodiment, the first indication information can be added to the MAC PDU, so there is no need to change the physical layer encoding, mapping and other processes. The first indication information can also be generated at the physical layer, and can be in the form of downlink control information, that is, the first DCI, and the first indication information is carried in the first DCI.

[0135] The first indication information may also be the first indication information configured by the network device through high-layer signaling. For example, the high-layer signaling may include signaling such as SIB (System Information Block), RRC (Radio Resource Control), and MAC (Media Access Control).

[0143] The first PDSCH or the first PDSCH group is excluded.

[0144] When there are multiple PDSCHs without corresponding PDCCH transmission in a time slot, it means that multiple PDSCHs without corresponding PDCCH transmission overlap in the time domain. To reduce collision, the first PDSCH or the first PDSCH group in the multiple PDSCHs in the time slot needs to be excluded first. It can be understood that there is no need to receive or modulate the first PDSCH or the first PDSCH group, and / or there is no need to generate or report HARQ-ACK for the first PDSCH or the first PDSCH group. This reduces energy consumption and improves PUCCH transmission reliability.

[0147] Each PDSCH has a corresponding index. After excluding the first PDSCH or the first PDSCH group from multiple PDSCHs, it is only necessary to receive the PDSCH with the lowest SPS configuration index in the first set. The first set includes multiple PDSCHs without corresponding PDCCH transmissions in a time slot, and after excluding the first PDSCH or the first PDSCH group, the remaining activated PDSCHs without corresponding PDCCH transmissions, that is, it is only necessary to receive the PDSCH with the lowest index among the remaining activated PDSCHs without corresponding PDCCH transmissions after excluding the first PDSCH or the first PDSCH group, thereby reducing the number of PDSCH receptions, reducing energy consumption, and improving PUCCH transmission reliability.

[0148] Optionally, the method may further include: demodulating the PDSCH with the lowest SPS configuration index in the first set, and / or generating or reporting HARQ-ACK for the PDSCH with the lowest SPS configuration index in the first set.
