Description

Technical Field

[0001] The present invention relates to the field of electronic communication technologies, and particularly relates to a transmission channel configuration method, system, network-side device, and terminal device based on wireless communication. Background Art

[0002] In the downlink transmission of 5G NR (a global 5G (fifth-generation mobile communication technology) standard with a new air interface design based on OFDM (orthogonal frequency division multiplexing)), network-side devices such as base stations can perform downlink data transmission by scheduling the PDSCH (physical downlink share channel, used to carry downlink data messages) of semi-persistent scheduling (SPS). The PDSCH of semi-persistent scheduling is configured with a transmission period and a configuration index by RRC (radio resource control), and performs periodic transmission after being activated by DCI (downlink control information, which consists of multiple parameter fields and is sent to the user through PDCCH). In the 3GPP Rel-16 (standard specification) version, up to 8 groups of PDSCHs of semi-persistent scheduling can be configured simultaneously.

[0003] During semi-persistent scheduling transmission, the time slot offset value K1 between the PDSCH and the PUCCH is indicated by DCI. The set of K1 values, dl-DataToUL-ACK, is configured by RRC, and a certain value in the set is indicated by the PDSCH-to-HARQ_feedback timing indicator field of DCI.

[0004] In a TDD (time division duplex) system, if the PUCCH resources for reporting HARQ (hybrid automatic repeat request)-ACK (Acknowledgement) of semi-persistent scheduling may conflict with the RRC-configured semi-static downlink / flexible symbols, the PUCCH will be discarded at this time, and the semi-persistent scheduling cannot perform HARQ-ACK feedback, and the transmission performance will be affected.

[0005] When the PUCCH resources fed back by one or more PDSCHs of semi-persistent scheduling are delayed to a later uplink time slot or symbol transmission due to TDD conflict problems, the current protocol discussion does not consider the impact caused by TRP (transmission reference point) / beam switching. That is, the current protocol discussion assumes that all beams corresponding to the PUCCH resources belong to the same TRP.

[0006] As described above, for each UCI (Uplink Control Indication) size, there is only one candidate PUCCH for the semi-statically scheduled PUCCH resource. When the beam of the PUCCH originally indicated by the activation DCI of the semi-statically scheduled PDSCH corresponds to TRP1, but after postponement, due to a change in the UCI size or a change in the semi-statically scheduled PUCCH resource in the SPS-PUCCH-List (list) configured by RRC, the beam of the reselected PUCCH resource may correspond to TRP2. In this case, the terminal device (UE) can only feedback to continue postponing or dropping, which will cause excessive transmission delay or significant performance loss. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the defect that in the prior art, uplink PUCCH transmission may be at different TRPs, and the terminal device can only feedback to continue postponing or dropping, resulting in excessive transmission delay or significant performance loss, and to provide a transmission channel configuration method, system, network-side device, and terminal device.

[0104] The present invention will be further described below by way of embodiments, but the present invention is not limited thereto.

[0105] In semi-static scheduling transmission, the time slot offset value K1 between the PDSCH and the PUCCH is indicated by DCI. The set of K1 values, dl-DataToUL-ACK, is configured by RRC, and a certain value in the set is indicated by the PDSCH-to-HARQ_feedback timing indicator field of DCI.

[0106] In a TDD system, if the PUCCH resources for semi-static scheduling of HARQ-ACK reporting may conflict with the RRC-configured semi-static downlink / flexible symbols, the PUCCH will be discarded at this time, and semi-static scheduling cannot perform HARQ-ACK feedback, and the transmission performance will be affected.

[0107] Refer to the agreement reached in the 3GPP Re-17 RAN1#104-e meeting to solve the problem of HARQ-ACK discarding in semi-static scheduling in TDD systems. The HARQ-ACK of semi-static scheduling can be postponed to the available time slots later, but how to specifically select the PUCCH resources for carrying still needs further discussion.

[0108] Refer to the relevant protocol for HARQ-ACK PUCCH resource selection in Rel-16 URLLC (ultra-reliable low latency communications): In the selection of PUCCH resources for HARQ-ACK of dynamic PDSCH, RRC will configure up to four groups of PUCCH resource sets for dynamic PDSCH. There are multiple PUCCH resources in each group. The UE determines the resource group according to the size of the UCI of the feedback bits, and then determines the selected PUCCH resource according to the PRI (primary rate interface) field in the DCI. In the selection of PUCCH resources for HARQ-ACK of semi-static scheduled PDSCH, RRC will configure a semi-static scheduled SPS-PUCCH-AN list (SPS-PUCCH-AN-List) for the semi-static scheduled PDSCH, which contains up to 4 semi-static scheduled PUCCH resources. The UE determines the semi-static scheduled PUCCH resource for transmission according to the size of the UCI of the feedback bits.

[0109] Refer to the Rel-16 MIMO (multiple input multiple output technology) multi-TRP related protocol. The base station will configure a set of PUCCH-SpatialRelationInfo for each PUCCH resource through RRC, and then activate one of the PUCCH-SpatialRelationInfo through MAC-CE (MAC Control Element). Each PUCCH-SpatialRelationInfo will configure a reference signal, which indicates the beam used for PUCCH transmission. Among all the beams configured by RRC, a part of the beams will correspond to TRP1 reception, and a part of the beams will correspond to TRP2 reception.

[0110] When the PUCCH resources fed back by one or more semi-static scheduled PDSCHs are postponed to the subsequent uplink time slots or symbols for transmission due to TDD conflict problems, the current protocol discussion does not consider the impact caused by TRP / beam switching. That is, the current protocol discussion assumes that all the beams corresponding to the PUCCH resources belong to the same TRP.

[0111] As described above, for each UCI size, there is only one candidate PUCCH for the semi-statically scheduled PUCCH resource. When the beam of the PUCCH originally indicated by the activation DCI of the semi-statically scheduled PDSCH corresponds to TRP1, but after postponement, due to a change in the UCI size, or a change in the semi-statically scheduled PUCCH resource in the SPS-PUCCH-List configured by RRC, the beam of the reselected PUCCH resource may correspond to TRP2. In this case, the terminal device can only feedback to continue postponing or discarding, which will cause excessive transmission delay or significant performance loss.

[0112] To overcome the above-mentioned existing defects, this embodiment provides a transmission channel configuration method, which is applied to a terminal device. The transmission channel configuration method includes: receiving the PUCCH resource feedback by the semi-statically scheduled PDSCH; in response to the postponement of the PUCCH resource feedback by the semi-statically scheduled PDSCH to a later uplink time slot or symbol transmission and the generation of a change in the PUCCH resource, selecting a PUCCH resource that meets the rule conditions from a dynamic PUCCH resource group according to a predefined rule, so that the transmission of the postponed PUCCH resource and the transmission of the previous PUCCH resource are received by the same TRP.

[0113] In this embodiment, the above-mentioned transmission channel configuration method is implemented based on the FR (Frequency Range) 2 (high frequency) system, but its application scenario is not specifically limited.

[0114] In this embodiment, for the content regarding the high-layer and physical-layer configurations in the 5G NR protocol, reference can be made to: Protocol [1] TS38.331, Radio Resource Control (RRC) protocol specification; Protocol [2] TS 38.213, Physical layer procedures for control.

[0115] As an optional embodiment, as Figure 1 shown, the above-mentioned transmission channel configuration method applied to a terminal device mainly includes the following steps:

[0116] Step 101: Receive the PUCCH resource.

[0117] In this step, based on the network-side device transmitting downlink data by scheduling the semi-statically scheduled PDSCH, receive the PUCCH resource feedback by the semi-statically scheduled PDSCH.

[0118] Step 102: The PUCCH resources in response to the PDSCH feedback of semi-static scheduling are postponed to a later uplink time slot or symbol for transmission, resulting in a change in the PUCCH resources, triggering the selection of the corresponding scenario.

[0119] In this step, considering the possible different TRPs for the FR2 uplink PUCCH resource transmission, different PUCCH resource selection schemes are proposed for different scenarios, thus triggering the selection of the corresponding scenario.

[0120] In this embodiment, mainly the following three different scenarios are provided, namely:

[0121] Scenario 1: The PUCCH resource feedback of other dynamic PDSCHs is not included in the postponed uplink slot or uplink symbol.

[0122] Scenario 2-1: The PUCCH resource feedback of other dynamic PDSCHs is included in the postponed uplink slot or uplink symbol and the corresponding TRP is the same as that of the PUCCH resource of the original dynamically scheduled PDSCH.

[0123] Scenario 2-2: The PUCCH resource feedback of other dynamic PDSCHs is included in the postponed uplink slot or uplink symbol and the corresponding TRP is different from that of the PUCCH resource of the original dynamically scheduled PDSCH.

[0124] Step 103: Select the specific selection scheme of the PUCCH resources according to different scenarios.

[0125] For Scenario 1, in this step, the following two specific selection schemes of the PUCCH resources, namely Scheme 1-1 and Scheme 1-2, are provided.

[0126] Scheme 1-1: In this step, 2 semi-static scheduled SPS-PUCCH-AN resource IDs are configured in the semi-static scheduled SPS-PUCCH-AN list on each slot to correspond to different TRP receptions.

[0127] Specifically, in the SPS-PUCCH-AN-list on each slot configured by RRC, 2 SPS PUCCH resources are configured corresponding to 2 SpatialRelationInfo respectively under each maximum payload size, where each SpatialRelationInfo corresponds to a different TRP reception. The following gives specific codes as an example, but is not limited to this code form.

[0128]

[0129] That is, an additional semi-static scheduling SPS-PUCCH-AN resource ID is added to the signaling.

[0130] When selecting the above Scheme 1-1, the transmission opportunity after the semi-static scheduling feedback is postponed is increased in the FR2 scenario, ensuring that a PUCCH resource for semi-static scheduling with the same TRP can be found for feedback transmission in any UCI size case, thereby effectively reducing the latency and improving the transmission reliability.

[0131] Scheme 1-2: In this step, if the PUCCH resource feedback for other dynamic PDSCHs is not included in the postponed uplink slot or uplink symbol, a PUCCH resource that meets the rule conditions is selected from the dynamic PUCCH resource group according to the predefined rules.

[0132] Among them, the predefined rules include any one or more of the following rules: Rule 1, select the PUCCH resource with the earliest start symbol corresponding to the same TRP from the PUCCH resource group corresponding to the UCI bit size; Rule 2, select the PUCCH resource with the earliest end symbol corresponding to the same TRP from the PUCCH resource group corresponding to the UCI bit size; Rule 3, select the PUCCH resource with the smallest PUCCH resource index corresponding to the same TRP from the PUCCH resource group corresponding to the UCI bit size.

[0133] Preferably, the predefined rules at least include: Rule 1, select the PUCCH resource with the earliest start symbol corresponding to the same TRP from the PUCCH resource group corresponding to the UCI bit size.

[0134] Preferably, the predefined rules further include: in response to the non-existence of a PUCCH resource corresponding to the same TRP in the PUCCH resource group corresponding to the UCI bit size, select according to the above various rules from the PUCCH resource group corresponding to a larger UCI bit size.

[0135] The above Scheme 1-2 is based on the premise that the PDSCH feedback of the postponed semi-static scheduling can use the PUCCH resources configured by the dynamic PDSCH.

[0136] When selecting the above Scheme 1-2, there are more candidate resources and higher flexibility, effectively reducing the transmission latency and ensuring the transmission performance.

[0137] Specifically, referring to Figure 2 As shown, the PUCCH corresponding to the PDSCH activation DCI of the semi-static scheduling indicates TRP1. Therefore, after postponement, the one selected according to Rule 1 of Scheme 1-2 is PUCCH2, the one selected according to Rule 2 is PUCCH1, and the one selected according to Rule 3 is PUCCH1.

[0138] For scenario 2-1, according to the existing Rel-16 / Rel-17 rules, that is, find the PUCCH resource set according to the total size of the UCI bits fed back in the current slot, and determine the transmitted PUCCH resource according to the PRI indication.

[0139] However, there may be a problem: if the multiplexed UCI payload size exceeds the current maxpayloadsize, it is necessary to find the PUCCH resource from the upper-level PUCCH resource set. At this time, the PUCCH resource corresponding to the PRI may correspond to the beams of different TRPs.

[0140] Therefore, in this step, the following two specific selection schemes for PUCCH resources, namely Scheme 2-1-1 and Scheme 2-1-2, are provided.

[0141] Scheme 2-1-1: In this step, if the PUCCH resource indicated in the original DCI corresponds to the beams of different TRPs, it is directly discarded (dropped). This scheme is relatively simple to implement and improves efficiency.

[0142] Scheme 2-1-2: In this step, if the PUCCH resource feedback of other dynamic PDSCHs is included in the postponed uplink slot or uplink symbol and the corresponding TRP is the same as that of the PUCCH resource of the originally dynamically scheduled PDSCH, and if the PUCCH resource indicated in the original DCI corresponds to the beams of different TRPs, select the PUCCH resource that meets the rule conditions from the dynamic PUCCH resource set according to the predefined rules.

[0143] Among them, the predefined rules are similar to those in Scheme 1-2, and the predefined rules include any one or more of the following rules: Rule 1: Select the PUCCH resource with the earliest start symbol corresponding to the same TRP from the PUCCH resource set; Rule 2: Select the PUCCH resource with the earliest end symbol corresponding to the same TRP from the PUCCH resource set; Rule 3: Select the PUCCH resource with the smallest PUCCH resource index corresponding to the same TRP from the PUCCH resource set.

[0144] Preferably, the predefined rules at least include: Rule 1: Select the PUCCH resource with the earliest start symbol corresponding to the same TRP from the PUCCH resource set.

[0145] When Scheme 2-1-2 is selected, the transmission delay is effectively reduced and the transmission performance is guaranteed.

[0146] Specifically, refer to Figure 3As shown, there is originally a PUCCH 5 indicated by DCI in the uplink time slot. However, after multiplexing, the UCI becomes larger, and the corresponding PUCCH resource group changes. But the PUCCH 5 corresponding to the upper-level PUCCH resource group is TRP2. Therefore, the PUCCH resource needs to be reselected. According to Rule 1 of Scheme 2-1-2, the selected one is PUCCH2; according to Rule 2, the selected one is PUCCH1; and according to Rule 3, the selected one is PUCCH1.

[0147] For Scenario 2-2, in this step, the following four specific selection schemes for PUCCH resources are provided: Scheme 2-2-1, Scheme 2-2-2, Scheme 2-2-3, and Scheme 2-2-4.

[0148] Scheme 2-2-1: In this step, if the PUCCH resource corresponds to beams of different TRPs, it is directly discarded. This scheme is relatively simple to implement and improves efficiency.

[0149] Scheme 2-2-2: In this step, the PUCCH resource is postponed to the next available uplink slot. This scheme is relatively simple to implement and improves efficiency.

[0150] Scheme 2-2-3: Search for PUCCH resources with the same TRP in the PUCCH resource group. If it overlaps (partially overlaps) with the existing PUCCH in the current time slot, it is directly discarded. The search scheme is similar to Scheme 1-2, so it will not be elaborated one by one. This scheme has good generality, effectively reduces the transmission delay, and ensures the transmission performance. Moreover, it is compatible with Solution 1-2 in Scenario 1 and Solution 2-1-2 in Scenario 2-1.

[0151] Scheme 2-2-4: Search for PUCCH resources with the same TRP in the PUCCH resource group and without overlap with the current existing PUCCH (that is, PUCCH resources that do not overlap with the PUCCH resources of other dynamic PDSCHs). The search scheme is similar to Scheme 1-2, so it will not be elaborated one by one. This scheme can achieve the maximum performance gain, effectively reduces the transmission delay, and ensures the transmission performance.

[0152] Specifically, referring to Figure 4 As shown, there is originally a PUCCH5 indicated by DCI in the uplink time slot and it corresponds to TRP2. Then, according to the rule of Scheme 2-2-3, PUCCH2 is found. However, PUCCH2 and PUCCH5 conflict in the time domain, so it is discarded.

[0153] Referring to Figure 4As shown in the figure, PUCCH5 indicated by DCI originally exists in the uplink time slot and corresponds to TRP2. Then, according to the rules of Solution 2-2-4, PUCCH1 is found, that is, PUCCH1 corresponding to TRP1 that does not conflict with PUCCH5 is found for transmission.

[0154] Step 104: Select and configure appropriate PUCCH resources so that the transmission of the postponed PUCCH resources and the transmission of the previous PUCCH resources are received by the same TRP.

[0155] In this step, appropriate PUCCH resources are selected and configured according to Step 103 so that the transmission of the postponed PUCCH resources and the transmission of the previous PUCCH resources are received by the same TRP.

[0156] This embodiment also provides a transmission channel configuration method applied to a network-side device. The transmission channel configuration method includes the following steps: performing downlink data transmission by scheduling a semi-statically scheduled PDSCH to configure PUCCH resources according to the above-mentioned transmission channel configuration method.

[0157] This embodiment also provides a transmission channel configuration method, including the steps in the transmission channel configuration method applied to a network-side device as described above and the steps in the transmission channel configuration method applied to a terminal device as described above.

[0158] The transmission channel configuration method provided in this embodiment takes into account the possible situations of FR2 uplink PUCCH transmission at different TRPs, and provides effective solutions for selecting and configuring PUCCH resources for different situations, thereby effectively ensuring that the transmission of the postponed PUCCH resources and the transmission of the previous PUCCH resources are received by the same TRP, achieving the minimum transmission delay, and thus avoiding performance loss.

[0163] Among them, the predefined rule further includes: in response to the non-existence of a PUCCH resource corresponding to the same TRP in the PUCCH resource group corresponding to the UCI bit size, select from the PUCCH resource group corresponding to a larger UCI bit size.
