Method and device for determining physical uplink control channel PUCCH

Abstract

The present application provides a method and device for determining a physical uplink control channel PUCCH, which is applied to a user equipment supporting multiple carriers and includes: when a first DCI that triggers HARQ ACK information feedback is detected, a step of determining a timer timeout moment based on the first DCI and a step of detecting a second DCI when the timer timeout moment has not arrived, wherein the second DCI triggers HARQ ACK information feedback, and the HARQ ACK information feedback triggered by the second DCI corresponds to the same time slot as the HARQ ACK information feedback triggered by the first DCI. The method avoids repeated configuration of the PUCCH channel by setting a timeout moment, and all HARQ‑ACK information that meets the protocol multiplexing timing is fed back on the selected PUCCH resource, thereby avoiding the loss of HARQ‑ACK information of certain TBs and causing downlink retransmission, thereby improving the downlink rate.

Description

Technical Field

[0001] The present application relates to the field of communications, and in particular, to a method for determining a physical uplink control channel PUCCH, an apparatus for determining a physical uplink control channel PUCCH, a computer-readable storage medium, and an electronic device. Background Art

[0002] When the user equipment receives a PDSCH dynamically scheduled by downlink control information and corresponding to a certain HARQ ProcessID, or receives an SPSPDSCH configured by a higher layer and activated by specific downlink control information, or receives a special downlink control information that does not schedule PDSCH but indicates SPSPDSCH Release or SCell Dormancy, the user equipment needs to feedback the HARQ-ACK information of these downlink receptions on the PUCCH resources configured on the network side, including two cases:

[0003] The first case: the uplink control information that the user equipment needs to feedback in a certain time slot only includes the HARQ-ACK information and / or SR corresponding to the SPSPDSCH. The user equipment determines the PUCCH resource based on the dedicated PUCCH resource set configured by the network side and the number of bits of the uplink control information, and does not need downlink control information to indicate the PUCCH resource.

[0004] The second case: the user equipment needs to include the HARQ-ACK information triggered by the downlink control information in the uplink control information fed back on a certain time slot. The user equipment needs to generate a HARQ-ACK codebook corresponding to multiple PDSCH reception opportunities, and select a PUCCH resource set with a suitable bit capacity from the PUCCH resource set list configured on the network side according to the number of bits in the HARQ-ACK codebook, and then select a PUCCH resource from the selected PUCCH resource set to carry the generated HARQ-ACK codebook. The HARQ-ACK codebook here contains the HARQ-ACK information of the SPSPDSCH.

[0005] For the second situation mentioned above, there are roughly two existing solutions:

[0006] Solution 1: Every time a downlink control message that feeds back HARQ-ACK information in the same time slot is detected, the user equipment regards this downlink control message as the last downlink control message and calculates the PUCCH resource selection once;

[0007] Solution 2: Trigger PUCCH resource selection in an interruption message with a time slot period. This resource selection solution is not based on the last downlink control information.

[0008] The above two solutions are simple in logic and easy to implement, but have the following disadvantages:

[0009] Solution 1 is only applicable to scheduling scenarios where downlink control information is relatively sparse. For scenarios where downlink control information is densely scheduled, such as multi-carrier and multi-HARQ processes, before sending the PUCCH channel, it is highly likely that the PUCCH resources will be repeatedly calculated multiple times, thereby triggering multiple PUCCH resource conflict resolutions, multiple PUSCH and PUCCH resource conflict resolutions, multiple PUCCH / PUSCH channel configurations and other operations. This solution will greatly increase the amount of calculation for HARQ-ACK feedback or uplink control information feedback, which is not conducive to saving chip power consumption and may cause tight processing timing.

[0010] Solution 2 does not comply with the protocol first, and cannot select PUCCH resources based on the last downlink control information. Moreover, in the tight timing scenario of K1=0 or K1=1 (where K1 is the feedback timing interval of HARQ-ACK, i.e., the timing interval of PDSCH and PUCCH), it is possible that some HARQ-ACK information for emergency downlink scheduling may be lost due to too early determination of PUCCH resources and too early configuration of PUCCH channel transmission, resulting in the network side failing to receive the HARQ information of some downlink TBs in time, causing TB retransmission, which will increase the downlink transmission delay and reduce the downlink transmission rate, and fail to achieve the ultra-low delay and ultra-reliability indicators of URLLC. Summary of the invention

[0011] The main purpose of the present application is to provide a method for determining a physical uplink control channel PUCCH, a device for determining a physical uplink control channel PUCCH, a computer-readable storage medium and an electronic device, so as to at least solve the problem that the existing HARQ-ACK PUCCH resource selection scheme has the risk of timing compression.

[0055] As introduced in the background technology, in the prior art, when a new wireless (5G) user equipment detects multiple downlink control information that triggers HARQ-ACK feedback and feeds back HARQ-ACK in the same time slot, the user equipment should sort these downlink control information in ascending order of the serving cell index and then in ascending order of the receiving start timing, and determine the last received downlink control information to obtain the PUCCH resource indication field therein. In particular, in the multi-carrier multi-HARQ process scenario, the number of the above downlink control information can be large, and the NR user equipment needs to determine the Last downlink control information in a timely manner before it can determine the PUCCH resource for feedback HARQ-ACK.

[0056] For new wireless (5G) user equipment, downlink control information detection is bursty, and the user equipment cannot predict which OFDM symbols the network side sends downlink control information. To determine the last downlink control information, the user equipment must limit a time range in which the downlink control information can be detected. To this end, the new wireless (5G) protocol defines a minimum protection interval between the end of the last downlink control information and the start of the last determined PUCCH resource. Based on this, the new wireless (5G) user equipment can determine the limit timing of the last downlink control information and start PUCCH resource selection in time.

[0057] In order to solve the problem of the risk of timing compression in the existing HARQ-ACK PUCCH resource selection scheme, the embodiments of the present application provide a method for determining a physical uplink control channel PUCCH, an apparatus for determining a physical uplink control channel PUCCH, a computer-readable storage medium and an electronic device.

[0058] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0059] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal according to an embodiment of the present invention, in accordance with a method for determining a physical uplink control channel PUCCH. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1The structure shown is for illustration only and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0060] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for determining the physical uplink control channel PUCCH in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0061] In this embodiment, a method for determining a physical uplink control channel PUCCH running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0062] Figure 2 FIG. 1 is a flow chart of a method for determining a physical uplink control channel PUCCH according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0063] Step S201, when a first DCI that triggers HARQ ACK information feedback is detected, a step of determining a timer timeout moment is performed based on the first DCI, and a step of detecting a second DCI when the timer timeout moment has not been reached, wherein the second DCI triggers HARQ ACK information feedback, and the HARQ ACK information feedback triggered by the second DCI corresponds to the same time slot as the HARQ ACK information feedback triggered by the first DCI.

[0064] Specifically, the NR protocol defines a Last DCI restricted timing condition applicable to multi-carrier multi-HARQ process scenarios: After the UE selects a PUCCH resource 0 (i.e., the initial PUCCH), this PUCCH0 can be triggered by the downlink DCI detected in the past or by the SPS PDSCH. Determining the initial PUCCH can determine the target time slot, which can more accurately determine the target PUCCH and avoid repeated configuration.

[0065] The step of determining the timeout moment of the timer includes:

[0066] Step S301, determining a PUCCH resource for feeding back HARQ ACK information according to the currently detected DCI;

[0067] Step S302, determining the end times corresponding to the carriers with different subcarrier spacings respectively according to the currently determined start time of the PUCCH resource;

[0068] Step S303: determining a timer expiration time according to the latest cut-off time among all the currently determined cut-off times, wherein the timer expiration time is later than the latest cut-off time and earlier than the currently determined start time of the PUCCH resource.

[0069] Specifically, Figure 3 As shown, the latest cut-off time is separated from the start time of the currently determined PUCCH resource by a preset time interval, and the preset time interval Gap is generally calculated by formula 1:

[0070] Gap=N3×(2048+144)×k×2 -μ ×T c (Formula 1)

[0071] Among them, N3 is a value of the protocol, which is related to μ. The value of N3 can be obtained by looking up the table, k = 64, T c is a fixed value. Generally, T c =1 / (480KHz×4096).

[0072] The cut-off time on the current carrier is obtained by taking the time interval of Gap from the start time of PUCCH0; this cut-off time limits the end time of the last DCI, and only the downlink DCI received before this cut-off time can trigger a PUCCH channel sent on the same time slot n. The parameter μ is the minimum value of the SCS of the PDCCH that schedules the above DCI and the SCS of the PUCCH. Therefore, in a multi-carrier multi-downlink SCS scenario, the cut-off time of each carrier may not be aligned at the same time. When a new downlink DCI arrives, it may indicate a new PUCCH resource, so the cut-off time on the current downlink carrier may change relative to the start time of the new PUCCH resource.

[0073] In addition, a timeout point of the registration timer (i.e., the timer timeout moment) is obtained by delaying the time from the deadline (i.e., the latest deadline) by T_Delay, and the UE is triggered to start processing PUCCH resource selection and UCI processing through the timer timeout event. Considering the analysis delay T_Delay of CORESET, the NR UE can delay the above deadline by T_Delay to obtain a time point at which the timer can be registered (i.e., the timer timeout moment). In this way, the timing and result of PUCCH resource selection can be determined very accurately.

[0074] The step of performing the second DCI detection step when the timer timeout moment has not arrived includes:

[0075] Step S401, when the timer timeout moment has not arrived and the second DCI is detected, the step of determining the timer timeout moment is performed based on the second DCI, and when the re-determined timer timeout moment has not arrived, the step of detecting the second DCI is performed;

[0076] Step S402: When the timer times out and the second DCI is not detected, the currently determined PUCCH resource is used to feed back HARQ ACK information corresponding to the first DCI and all the second DCIs.

[0077] Specifically, every time a new downlink DCI is detected and HARQ-ACK is to be fed back on time slot n, the cutoff time on each carrier needs to be refreshed, and then a new timer timeout time (i.e., timer timeout time) is determined according to the above method, which involves the cancellation and re-registration of the timer. This can more accurately determine the timing and result of PUCCH resource selection.

[0078] The specific implementation steps of determining the timeout time of the timer according to the latest deadline among all currently determined deadlines are as follows:

[0079] Step S501, determining the decoding delay of the CORESET corresponding to the PDCCH carrying the currently detected DCI;

[0080] Step S502: determining the timeout time of the timer according to the latest deadline of all currently determined deadlines and the currently determined decoding delay.

[0081] Specifically, in a scenario where there are multiple carriers and the SCSs of the downlink carriers are different, such as Figure 4 As shown, taking 2DL CC as an example, the deadlines on the two CCs can be different; the UE needs to comprehensively consider the deadlines of the two CCs to determine the deadline at which the last DCI may be received; relative to the deadline finally determined on the multi-carrier. Taking into account the parsing delay T_Delay of CORESET (decoding delay of CORESET), the NR UE can delay the above Deadline by T_Delay to obtain a time point at which the timer can be registered; each time a new downlink DCI is detected and HARQ-ACK is also to be fed back on slot n, the Deadline on each carrier needs to be refreshed, and then the new Timer timeout moment is determined according to the above method, which involves the cancellation and re-registration of the Timer. This can be done

[0082] The specific implementation steps of the above step S501 are as follows:

[0083] Step S5011, determining a decoding delay of a CORESET corresponding to the PDCCH according to the number of CCEs corresponding to the PDCCH carrying the currently detected DCI, the aggregation level, and the processing capability of the user equipment.

[0084] Specifically, at the cut-off time, the CORESET decoding delay T_Delay needs to be evaluated based on factors such as the number of CCEs, PDCCH aggregation level, and NR UE processing capability.

[0085] This can support the PUCCH emergency feedback mechanism of K1=0 and K1=1, avoid losing the HARQ-ACK information of the emergency scheduled downlink T, reduce TB retransmission, and improve the downlink rate, where K1 is the HARQ-ACK feedback timing interval (i.e., the timing interval of PDSCH and PUCCH).

[0086] The specific implementation steps of using the currently determined PUCCH resource to feed back the HARQ ACK information corresponding to the first DCI and all the second DCIs are as follows:

[0087] Step S601, performing conflict processing and multiplexing processing on the UCI including the HARQ ACK information corresponding to the first DCI and several UCIs including the HARQ ACK information corresponding to the second DCI on the currently determined PUCCH resource to obtain processed UCI;

[0088] Step S602: Feedback the processed UCI using the currently determined PUCCH resource.

[0089] Specifically, in this way, UCI conflicts and multiplexing can be calculated at one time to avoid repeated calculations, and all HARQ-ACK information that meets the protocol multiplexing timing can be fed back on the selected PUCCH resources to avoid the loss of HARQ-ACK information of some TBs and cause downlink retransmission, thereby avoiding a decrease in downlink rate.

[0090] The above-mentioned method for determining the physical uplink control channel PUCCH of the present application is applied to a user equipment supporting multiple carriers. When the first DCI that triggers the HARQ ACK information feedback is detected, the step of determining the timer timeout moment is performed based on the first DCI, and the step of detecting the second DCI is performed when the timer timeout moment has not arrived, wherein the second DCI triggers the HARQ ACK information feedback, and the HARQ ACK information feedback triggered by the second DCI corresponds to the same time slot as the HARQ ACK information feedback triggered by the first DCI. The method calculates the UCI conflict and multiplexing at one time by setting the timer timeout moment to avoid repeated calculations; avoids repeated configuration of the PUCCH channel, and feeds back all the HARQ-ACK information that meets the protocol multiplexing timing on the selected PUCCH resource, avoids the loss of HARQ-ACK information of some TBs and causes downlink retransmission, and improves the downlink rate. The problem of the existing HARQ-ACKPUCCH resource selection scheme with low downlink rate and the risk of timing squeeze is solved.

[0091] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for determining the physical uplink control channel PUCCH of the present application will be described in detail below in combination with specific embodiments.

[0092] This embodiment relates to a specific method for determining a physical uplink control channel PUCCH, such as Figure 5 As shown, the following steps are included:

[0093] Step S1: When determining for the first time that HARQ-ACK information needs to be fed back on PUCCH slot n, for example, when receiving downlink DCI that triggers HARQ-ACK information feedback on PUCCH slot n for the first time or needs to feed back HARQ-ACK information of SPSPDSCH on PUCCH slot n, the NR UE may first determine a PUCCH resource;

[0094] Step S2: Calculate the deadline on each CC according to the deadline calculation formula and take the latest deadline and combine it with the CORESET decoding delay evaluation value to determine a timer timeout moment, and register the timer;

[0095] Step S3: If the Timer times out, the PUCCH resource can be directly selected according to the PUCCH resource indication field of the last DCI, and the UCI conflict processing and UCI multiplexing processing on the PUCCH channel can be started;

[0096] Step S4: If the PDSCH decoding information has been collected and filled into the HARQ-ACK codebook, then configure the PUCCH channel and prepare to send the PUCCH; otherwise, loop step 4;

[0097] Step S5: If the timer has not timed out and a downlink DCI is received, a new PUCCH resource (which may remain unchanged) is selected according to the PUCCH resource indication field therein, and then the deadlines of each carrier are refreshed and the timer is re-registered; go to step 3.

[0098] Based on the LastDCI timing defined by the protocol and the Timer registration and triggering mechanism, the timing and result of PUCCH resource selection can be determined very accurately. Calculating UCI conflicts and multiplexing at one time can avoid repeated calculation and repeated configuration of PUCCH channels; and all HARQ-ACK information that meets the protocol multiplexing timing can be fed back on the selected PUCCH resources, avoiding the loss of HARQ-ACK information of some TBs and causing downlink retransmission, thereby avoiding a drop in downlink rate.

[0099] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
