Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a method, device and terminal for determining the number of PUCCH repeated transmissions. Background Art

[0002] In the communication system, the number of repeated transmissions of the Physical Uplink Control Channel (PUCCH) is semi-statically configured, and the number of repeated transmissions is associated with the format of the PUCCH. The number of repeated transmissions corresponding to each PUCCH format is fixed and is a value configured by high-level signaling. This makes it impossible for the terminal to dynamically adjust the number of repeated transmissions of the PUCCH based on the transmission scenario, resulting in the number of repeated transmissions of the PUCCH not necessarily being adapted to the transmission scenario, affecting the transmission performance of the terminal.

[0039] In conjunction with the accompanying drawings, the method, device and terminal for determining the number of PUCCH repeated transmissions provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0040] Please refer to Figure 2 , Figure 2 1 is a flow chart of a method for determining the number of PUCCH repetition transmissions provided in an embodiment of the present application, and the method may be applied to a terminal. Figure 2 As shown, the method comprises the following steps:

[0041] Step 202: The terminal determines the number of PUCCH repetition transmissions based on the target information.

[0042] The target information includes at least one of the following:

[0043] The number of bits of uplink control information (UCI);

[0044] First target bit rate;

[0045] Number of PUCCH symbols;

[0046] The number of resource elements (RE) of PUCCH;

[0047] Preset time;

[0048] Reference Signal Received Power (RSRP);

[0049] Path loss;

[0050] The number of repeated transmissions of other physical channels or messages during random access.

[0051] For example, the terminal may determine the number of repeated transmissions of the PUCCH based on the number of bits of the UCI; or, the terminal may determine the number of repeated transmissions of the PUCCH based on the number of bits of the UCI and the number of symbols of the PUCCH; or, the terminal may determine the number of repeated transmissions of the PUCCH based on the path loss (Pass-loss); or, the terminal may determine the number of repeated transmissions of the PUCCH based on the number of repeated transmissions of other physical channels or messages (e.g., message 1, message 3, message B, etc.) during the random access process. Of course, the terminal may also determine the number of repeated transmissions of the PUCCH based on the other target information mentioned above, which are not listed here one by one. How the terminal determines the number of repeated transmissions of the PUCCH based on the target information will be specifically described in the subsequent implementation methods.

[0052] It should be noted that the preset time may refer to the delay of UCI transmission, and the preset time will be specifically described in the subsequent implementation manner.

[0053] In an embodiment of the present application, the terminal can determine the number of repeated transmissions of the PUCCH based on at least one of the target information such as the number of UCI bits, the number of REs of the PUCCH, the number of PUCCH symbols, and thus the terminal no longer needs to determine the number of repeated transmissions based on the high-level signaling configuration, so that the terminal can autonomously and implicitly determine the number of repeated transmissions of the PUCCH. The terminal can also dynamically adjust the number of repeated transmissions of the PUCCH based on the target information to meet the corresponding transmission performance requirements and ensure the transmission performance of the terminal.

[0054] Optionally, when the target information includes the number of bits of the UCI and the first target code rate, and the PUCCH is repeatedly transmitted N times, N is determined based on the following method:

[0055] The ratio of the number of bits of the PUCCH repeated transmission to the number of bits that the resources can carry for N PUCCH repeated transmissions is less than or equal to the first target code rate, and the ratio of the number of bits of the PUCCH repeated transmission to the number of bits that the resources can carry for N-1 PUCCH repeated transmissions is greater than the first target code rate.

[0056] In this implementation, the terminal determines the number of repeated transmissions of the PUCCH N according to the number of bits of the UCI and the first target code rate. Specifically, in the case of repeated transmission of the PUCCH N times, it is necessary to satisfy that the ratio of the number of bits of the repeated transmission of the PUCCH to the number of bits that can be carried by the resources for the N repeated transmissions of the PUCCH is less than or equal to the first target code rate, and the ratio of the number of bits of the repeated transmission of the PUCCH to the number of bits that can be carried by the resources for the N-1 repeated transmissions of the PUCCH is greater than the first target code rate.

[0057] Among them, the number of bits of the PUCCH repeated transmission may be related to the number of bits of the UCI, the number of bits that can be carried by the resources for the N times of PUCCH repeated transmission may be related to the number of symbols of the PUCCH transmission UCI, or may also be related to the PUCCH format (format), such as the number of bits that can be carried by the resources for the N times of PUCCH repeated transmission corresponding to PUCCH format 2 and PUCCH format 3 may be different.

[0058] In this implementation manner, the number of bits of the PUCCH repeated transmission is related to at least one of the following:

[0059] The number of bits of the UCI, the number of bits of a cyclic redundancy check (CRC);

[0060] and / or,

[0061] The number of bits that can be carried by the resource for repeated PUCCH transmission is related to at least one of the following:

[0062] The modulation order of the PUCCH, the number of symbols of UCI transmitted by the PUCCH, the PUCCH format, and the number of resource blocks (RBs) configured by the PUCCH.

[0063] That is to say, when the target information is related to the number of UCI bits, the number of UCI bits may affect the number of PUCCH bits for repeated transmission, or the number of PUCCH bits for repeated transmission may also be related to the number of CRC bits; or the number of PUCCH bits for repeated transmission is related to the number of UCI bits and the number of CRC bits.

[0064] In addition, the number of bits that can be carried by resources for N times of PUCCH repetition transmission and the number of bits that can be carried by resources for N-1 times of PUCCH repetition transmission can be related to at least one of the modulation order of the PUCCH, the number of symbols of UCI transmitted by the PUCCH, the PUCCH format, and the number of RBs configured by the PUCCH. For example, the number of bits that can be carried by resources for N times of PUCCH repetition transmission can be related to the number of symbols of UCI transmitted by the PUCCH, or the number of bits that can be carried by resources for N times of PUCCH repetition transmission can be related to the modulation order of the PUCCH, etc., which are not listed one by one in this embodiment.

[0065] Wherein, in the case where the number of bits that can be carried by the resource for repeated transmission of the PUCCH is related to the number of RBs configured by the PUCCH, the number of RBs is determined based on any one of the following:

[0066] Configuration information of network-side devices;

[0067] The number of RBs for a single PUCCH transmission.

[0068] For example, the terminal may determine the number of RBs according to the configuration information of the network side device. For example, when the configuration information sent by the network side device indicates that the terminal implicitly determines the number of PUCCH repetition transmissions, the terminal determines the number of PUCCH RBs based on the configuration information.

[0069] Alternatively, the number of RBs of the PUCCH for N repeated transmissions may also be determined based on the number of RBs for a single PUCCH transmission. For example, the number of RBs of the PUCCH for N repeated transmissions may be the same as the number of RBs for a single PUCCH transmission, and the terminal determines the number of RBs of the PUCCH for N repeated transmissions by obtaining the number of RBs for a single PUCCH transmission.

[0070] It should be noted that the number of RBs for the single PUCCH transmission is determined based on the number of UCI bits and the number of UCI symbols transmitted by PUCCH, and the number of RBs for the single PUCCH transmission is less than the minimum number of RBs for the second target code rate, and the second target code rate is the UCI code rate for the single PUCCH transmission.

[0071] For example, for PUCCH format 2, PUCCH format 3 or PUCCH resources, a second target code rate will be configured. Before sending PUCCH, the terminal can determine the number of RBs required for a single PUCCH transmission based on the number of UCI bits and the number of UCI symbols transmitted by PUCCH, and make the determined number of RBs less than the minimum number of RBs for the second target code rate.

[0072] It should be noted that since the number of symbols transmitted by each PUCCH may be different, in the process of determining the number of RBs for a single PUCCH transmission, the number of symbols of the PUCCH UCI transmission may be configured by the network side device, or determined based on a preset number of PUCCH symbols.

[0073] The following will specifically illustrate how the terminal determines the number of PUCCH repetition transmissions N based on the number of UCI bits and the first target code rate through a specific implementation method.

[0074] Method 1

[0075] The number of PUCCH repetition transmissions N satisfies the following conditions:

[0076]

[0077] and

[0078] Among them, O UCI is the number of bits of UCI, O CRC is the number of bits of CRC, is the number of PUCCH RBs, is the value corresponding to the PUCCH format, Q is the number of symbols used to transmit UCI on PUCCH. m,n is the modulation order of PUCCH, and r is the first target code rate.

[0079] It should be noted that The value is different for different PUCCH formats; for PUCCH format 2: For PUCCH format 3: For PUCCH format 4: in The number of subcarriers in each RB.

[0080] In this implementation, the above parameters used for each transmission of PUCCH may be the same or different, such as the number of PUCCH symbols (including the number of UCI symbols and / or the number of demodulation reference signal (DMRS) symbols). In addition, since some repeated transmissions of PUCCH may conflict with downlink symbols, or some symbols are indicated by uplink signaling as not being available for uplink transmission, the number of symbols actually repeatedly transmitted by PUCCH may be different from the configured number of symbols. Alternatively, in the above formula, the terminal may use the configured number of PUCCH symbols to determine the number of repeated transmissions of PUCCH.

[0081] It should be noted that the above implementation method may be applicable to PUCCH format 1 or PUCCH resource configuration with a determined number of RBs. For example, in the NR system, the number of RBs of PUCCH format 4 is fixed to 1 RB. Optionally, the method 1 may be applicable to PUCCH format 4, PUCCH format 1, and PUCCH format 0; or it may be applicable to PUCCH format 2 and PUCCH format 3 when the number of RBs of PUCCH is a predefined value or is determined based on the configuration information of the network side device.

[0082] In this implementation, the number of RBs of the PUCCH can be determined based on the configuration information of the network side device. For example, the network side device can dynamically indicate the first target code rate after multiple repeated transmissions through high-level indication information or downlink control information (Downlink Control Information, DCI), and the number of repeated transmissions of the PUCCH is determined based on the above-mentioned method one, and the UCI code rate after the repeated transmission of the PUCCH is less than the first target code rate.

[0083] Method 2

[0084] The number of PUCCH repetition transmissions N satisfies the following conditions:

[0085]

[0086] and

[0087] The specific interpretation of each parameter in the above formula can refer to the description in the above method 1. The difference between method 2 and method 1 is that the number of RBs in the N-times repeated transmission of PUCCH in method 2 is determined according to the number of RBs in a single PUCCH transmission.

[0088] In this implementation, the number of RBs for a single PUCCH transmission is determined based on the number of UCI bits and the number of UCI symbols transmitted by the PUCCH, and the determined number of RBs is less than the minimum number of RBs for the second target code rate. Optionally, the second approach may be applicable to PUCCH format 2 and PUCCH format 3.

[0089] It should also be noted that, in the above implementation, the UCI code rate after the PUCCH is repeatedly transmitted N times is determined based on at least one of the following:

[0090] High-level signaling;

[0091] DCI.

[0092] That is to say, the UCI code rate after the terminal repeatedly transmits PUCCH N times needs to meet certain restrictions, which can be indicated by high-level signaling and / or dynamically indicated by DCI. For example, the UCI code rate after PUCCH is repeatedly transmitted N times is determined based on the high-level signaling received by the terminal, and then the specific value of the number of repeated transmissions N of PUCCH can be determined according to the UCI code rate indicated by the high-level signaling.

[0093] It can be understood that both the above-mentioned method 1 and method 2 determine the number of repeated transmissions of PUCCH through the number of UCI bits and the target code rate (such as the first target code rate and the second target code rate), so that the terminal can implicitly determine the number of repeated transmissions of PUCCH, and impose certain restrictions on the number of repeated transmissions to ensure that the delay of PUCCH repeated transmission is acceptable, thereby ensuring the uplink transmission performance of the terminal.

[0094] In the embodiment of the present application, in addition to determining the number of repeated transmissions of the PUCCH according to the above method, the terminal may also determine the number of repeated transmissions of the PUCCH in combination with other target information. For example, the number of repeated transmissions N of the PUCCH may also be determined based on the configuration information sent by the network side device.

[0095] Optionally, the method further comprises:

[0096] Receive configuration information sent by a network side device, where the configuration information is used to indicate that the number of repeated transmissions of the PUCCH is M;

[0097] The step 201 may be:

[0098] Based on the target information, the number of repeated transmissions N of the PUCCH is acquired, and M or N is determined as the number of repeated transmissions of the PUCCH.

[0099] That is, the network side device can configure the number of repeated transmissions of the terminal PUCCH to be M, and the terminal can determine the number of repeated transmissions of the PUCCH N based on the target information, for example, the number of repeated transmissions of the PUCCH N can be determined based on the above-mentioned method 1 or method 2. Finally, the terminal can determine the number of repeated transmissions of the PUCCH to be min(M, N) based on M and N, that is, the smaller value of M and N is determined as the number of repeated transmissions of the PUCCH; or, it can also determine the number of repeated transmissions of the PUCCH to be max(M, N), that is, the larger value of M and N is determined as the number of repeated transmissions of the PUCCH.

[0100] In this implementation mode, when the terminal receives an indication from the network side device that the repetition transmission of the PUCCH is M at this time, the terminal can still determine the number of repetition transmissions of the PUCCH N based on the above target information, and then finally determine M or N as the number of repetition transmissions of the PUCCH. In this way, the terminal can determine the number of repetition transmissions of the PUCCH more flexibly.

[0101] Optionally, the target information may also be related to a preset time; and the method may further include:

[0102] Obtaining the number of repeated transmissions L of the PUCCH of the terminal within the preset time;

[0103] The step 202 may also be:

[0104] Based on the target information, the number of repeated transmissions N of the PUCCH is obtained, and the smaller one of L and N is determined as the number of repeated transmissions of the PUCCH.

[0105] The preset time may also refer to the delay of UCI. In this implementation, the terminal obtains the number of times L that the PUCCH can be repeatedly transmitted within the preset time, and obtains the number of times N that the PUCCH is repeatedly transmitted based on the target information (except the preset time), compares the sizes of L and N, and determines the smaller one as the number of times the terminal can repeatedly transmit the PUCCH.

[0106] For example, the terminal may be required to complete repeated transmission of PUCCH within T time after the first transmission of PUCCH. If the end time of the repeated N transmissions exceeds T time, only the repeated transmissions corresponding to the time within T time are transmitted. That is, the L repeated transmissions that can be performed within T time are determined as the number of repeated transmissions of PUCCH of the terminal.

[0107] Optionally, the preset time is determined based on at least one of the following:

[0108] A first preset time after the start time of the first transmission of the PUCCH;

[0109] A preset number of subframes after the start time of the first transmission of the PUCCH;

[0110] A preset number of time slots after the start time of the first transmission of the PUCCH;

[0111] A preset number of symbols after the start time of the first transmission of the PUCCH.

[0112] For example, the preset time is T time after the start time of the first PUCCH transmission of the terminal; or, the preset time can also be a preset number of subframes (subframe) or a preset number of time slots (slot) or a preset number of symbols (symbol) after the start time of the first PUCCH transmission of the terminal; or, the preset time can also be determined by T time and a preset number of symbols after the start time of the first PUCCH transmission of the terminal; etc., which are not listed one by one in this embodiment.

[0113] Optionally, the preset time may also be determined based on a hybrid automatic repeat request acknowledgement (HARQ-ACK) of the PDSCH contained in the PUCCH. For example, when the PUCCH contains HARQ-ACK feedback of the PDSCH, and the HARQ-ACK is a HARQ-ACK of 1 PDSCH, the preset time may be determined based on at least one of the following:

[0114] A second preset time after the PDSCH transmission end time;

[0115] A preset number of subframes after the PDSCH transmission end time;

[0116] A preset number of time slots after the PDSCH transmission end time;

[0117] A preset number of symbols after the PDSCH transmission end time.

[0118] That is to say, if the PUCCH contains HARQ-ACK feedback of the PDSCH, the PUCCH can be restricted to complete transmission within a second preset time after the PDSCH completes transmission; optionally, the second preset time can be in units of the number of subframes, slots or symbols.

[0119] Alternatively, when the PUCCH includes HARQ-ACK feedback of the PDSCH, and the HARQ-ACK is HARQ-ACK of at least two PDSCHs, the preset time is:

[0120] The earliest time among the time points after the delays corresponding to at least two of the PDSCHs; or,

[0121] The latest time among the time points after the delays corresponding to at least two of the PDSCHs.

[0122] That is, if the PUCCH includes HARQ-ACK feedback of multiple (at least two) PDSCHs, the preset time may be the earliest time or the latest time among the time points after the delays corresponding to the multiple PDSCHs.

[0123] In an embodiment of the present application, the terminal can determine the number of repeated transmissions of the PUCCH based on a preset time or a delay of the UCI, and the preset time can be determined according to the time of the first transmission of the PUCCH or the HARQ-ACK feedback of the PDSCH, which provides more implementation methods for determining the number of repeated transmissions of the PUCCH, making the terminal more flexible in determining the number of repeated transmissions of the PUCCH, so as to ensure the uplink transmission performance of the terminal.

[0124] Optionally, the method may further include:

[0125] When the terminal repeatedly transmits the PUCCH for a number of times within the preset duration so that the code rate of the PUCCH transmission is greater than the preset code rate, the number of RBs is increased so that the code rate of the PUCCH transmission is less than the preset code rate.

[0126] That is to say, after the terminal determines the number of repeated transmissions of PUCCH, if the determined number of repeated transmissions does not meet the preset code rate requirement, for example, the number of repeated transmissions may be determined based on a preset time in the above-mentioned implementation manner or explicitly indicated by a network side device, resulting in a small number of repetitions, then the number of RBs for PUCCH transmission may be further increased so that the code rate of PUCCH transmission meets the preset code rate requirement, that is, is less than the preset code rate.

[0127] It can be understood that the terminal may first perform the step of determining the number of PUCCH repetition transmissions, and if the preset code rate requirement cannot be met, then perform the above-mentioned step of increasing the number of RBs, and the number of RBs finally determined is the minimum number of RBs that meets the preset code rate requirement. Among them, the finally determined number of RBs may be determined based on the number of UCI bits and the number of symbols of PUCCH transmitting UCI, and the finally determined number of RBs is less than the minimum number of RBs of the second target code rate, that is, the following conditions are met:

[0128]

[0129] and

[0130] Among them, the interpretation of each parameter in the above formula can refer to the specific description in the aforementioned method one. In this implementation, the method for making the final determined RB number less than the preset bit rate can be specifically referred to the description in the aforementioned method two, which will not be repeated here.

[0131] In the embodiment of the present application, the repeated transmission of the PUCCH may also be related to messages, RSRP, path loss, etc. during the random access process.

[0132] Optionally, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to message 4 in the random access process is located is determined based on at least one of the following:

[0133] the RSRP;

[0134] the path loss;

[0135] Target transmit power;

[0136] The number of repetitions of at least one of message 1, message 2, message 3, and message 4 during the random access process.

[0137] That is to say, for the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message 4 (MSG.4) is located, the terminal can determine it according to at least one of the measured RSRP, path loss, and target transmission power. For example, the measured RSRP and path loss correspond to a number of repetitions in a certain interval, and the corresponding relationship can be indicated by the network side device.

[0138] Alternatively, the number of repeated transmissions of the PUCCH where the HARQ-ACK of MSG.4 is located may be determined based on the number of repeated transmissions of at least one of message 1 (MSG.1), message 2 (MSG.2), message 3 (MSG.3) and message 4 (MSG.4) during the random access process.

[0139] Optionally, when the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message 4 is located is determined based on the number of repeated transmissions of message 1 or message 3 in the random access process, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message 4 is located is any one of the following:

[0140] The number of repeated transmissions of the message 1;

[0141] The number of repetitions of the message 3;

[0142] The product of the number of repeated transmissions of the message 1 and the first coefficient;

[0143] The product of the number of repeated transmissions of the message 3 and the second coefficient.

[0144] That is, the number of repetitions of the PUCCH where the HARQ-ACK of MSG.4 is located may be the same as the number of repetitions of MSG.1 or MSG.3, or may be the number of repetitions of MSG.1 or MSG.3 multiplied by a coefficient. For example, if the number of repetitions of MSG.3 is 4, and the second coefficient is 0.5, which may be predefined or indicated by a network-side device, the number of repetitions of the PUCCH where the HARQ-ACK of MSG.4 is located is 2.

[0145] Alternatively, the number of repeated transmissions of the PUCCH where the HARQ-ACK of MSG.4 is located may also be associated with the resource of the PUCCH. For example, each PUCCH resource is associated with a number of repetitions, and the network indicates the corresponding PUCCH resource in the PDCCH scrambled by the test cell radio network temporary identifier (TC-RNTI), and determines the number of repeated transmissions of the PUCCH where the HARQ-ACK of MSG.4 is located according to the resource.

[0146] Optionally, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message B of the random access process is located is determined based on at least one of the following:

[0147] the RSRP;

[0148] the path loss;

[0149] target transmit power;

[0150] The number of repetitions of message A or message B during random access.

[0151] That is to say, for the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to message B (MSG.B) is located, the terminal can determine it according to at least one of the measured RSRP, pathloss, and target transmit power. For example, the measured RSRP and pathloss correspond to a number of repetitions in a certain interval, and the corresponding relationship can be indicated by the network side device.

[0152] Alternatively, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to MSG.B is located may be determined based on the number of repeated transmissions of message A (MSG.A), for example, it may be the same as the number of repeated transmissions of MSG.A.

[0153] Optionally, when the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message B is located is determined based on the number of repeated transmissions of message A in the random access process, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to the message B is located is any one of the following:

[0154] The number of repetitions of the physical random access channel (PRACH) preamble in the message A;

[0155] The number of repeated transmissions of the physical uplink shared channel (PUSCH) in the message A;

[0156] The product of the number of PRACH preamble or PUSCH repetition transmissions of the message A and the third coefficient.

[0157] That is to say, the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to MSG.B is located is related to the number of repeated transmissions of MSG.A, for example, it may be the same as the number of repeated transmissions of the PRACH preamble or PUSCH in MSG.A, or it may be the number of repeated transmissions of the PRACH preamble or PUSCH in MSG.A multiplied by a coefficient. For example, the number of repeated transmissions of the PUSCH in MSG.A is 4, and the third coefficient is 0.5, which may be predefined or indicated by the network side device, then the number of repeated transmissions of the PUCCH where the HARQ-ACK corresponding to MSG.B is 2.

[0158] Alternatively, the number of repeated transmissions of the PUCCH where MSG.B's HARQ-ACK is located is associated with the PUCCH resources. The network indicates the corresponding PUCCH resource in the PDCCH encrypted by MSGB-RNTI, and then can determine the number of repeated transmissions of the PUCCH where MSG.B's HARQ-ACK is located based on the resource.

[0159] In the solution provided in the embodiment of the present application, the terminal can determine the number of repeated transmissions of PUCCH based on at least one of the target information such as the number of UCI bits, the number of REs of PUCCH, the preset time, the message in the random access process, etc., and thus the terminal no longer needs to determine it according to the number of repetitions configured by the high-level signaling, so that the terminal can autonomously and implicitly determine the number of repeated transmissions of PUCCH. The terminal can also actively and dynamically adjust the number of repeated transmissions of PUCCH based on the target information to meet the corresponding transmission performance requirements and ensure the transmission performance of the terminal.
