Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method and apparatus for determining PUCCH power control parameters. Background Technology

[0002] In New Radio (NR), the Physical Uplink Control Channel (PUCCH) is used to carry Uplink Control Information (UCI). The transmission power of PUCCH is determined based on the number of bits corresponding to the UCI. When PUCCH uses PUCCH format 2 / 3 / 4 and carries HARQ-ACK feedback information determined using the Type-2 Hybrid Automatic Repeat reQuest-ACK knowledge (HARQ-ACK) codebook, control parameters are used to calculate the PUCCH power.

[0003] However, the current method for determining the control parameters of PUCCH power cannot accurately obtain the number of downlink control information (DCI) messages that the terminal (UE) actually misses. This results in the determined PUCCH power being less than the power required for actual PUCCH transmission, thus affecting PUCCH transmission performance. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0118] This invention provides a method and apparatus for determining PUCCH power control parameters. The method and apparatus are based on the same concept, and since the principles underlying the problem are similar, their implementations can be mutually referenced; repeated details will not be elaborated further.

[0119] like Figure 1 As shown, an embodiment of the present invention provides a method for determining PUCCH power control parameters, comprising:

[0120] Step 101: The terminal obtains the number of downlink allocation index (DAI) cycles, the number of downlink control information (DCI) receptions, and the DAI value in the last received DCI.

[0121] The feedback information of the DCI is transmitted on the same Physical Uplink Control Channel (PUCCH). That is, the number of DCIs received by the terminal is the number of DCIs corresponding to the same PUCCH. Furthermore, the last DCI received by the terminal also corresponds to that PUCCH.

[0122] Step 102: The terminal determines the number of unreceived DCIs based on the DAI cycle count, the number of DCIs received, and the DAI value.

[0123] In this step, the terminal determines the number of unreceived DCIs based on the DAI loop count, the number of DCIs received, and the DAI value obtained in step 101. Of course, the determined number of unreceived DCIs refers to DCIs that were not received but correspond to the same PUCCH as the received DCIs.

[0124] Step 103: The terminal determines the control parameters of PUCCH power based on the number of DCIs that were not received.

[0125] In this step, the terminal can further determine the control parameters of the PUCCH power based on the number of DCIs that were not received as determined in step 102. At this time, the PUCCH power is the PUCCH transmission power, which transmits the feedback information of the DCIs.

[0126] Thus, following the steps described above, after obtaining the DAI cycle count, the number of DCI receptions, and the DAI value in the last received DCI, the terminal can accurately determine the number of unreceived DCIs by combining these information, thereby clarifying the control parameters for PUCCH power. Consequently, subsequent transmission of feedback information based on the PUCCH power determined by these control parameters avoids performance degradation because the determined PUCCH power will not be less than the actual power required for PUCCH transmission.

[0127] It should be understood that in this embodiment, the DAI cycle count is the number of times the terminal records the DAI value based on the DAI of the DCI transmitting feedback information in the same PUCCH. When the DAI in the current DCI is less than or equal to the DAI in the previous DCI, the DAI cycle count is incremented by 1. For example, in a single-carrier scenario (where the DCI only has Counter-Downlink Assignment Indication (C-DAI) and no Total-Downlink Assignment Indication (T-DAI)), such as... Figure 2As shown, the base station sends six DCIs for scheduling the Physical Downlink Shared Channel (PDSCH), namely DCI-1, DCI-2, ..., DCI-6. For these six DCIs, the base station instructs that their corresponding Hybrid Automatic Repeat Request-ACK (HARQ-ACK) be fed back on PUCCH-1. Assuming that the DAI counting bit width is 2 bits, i.e., the maximum counting range is 4, then the C-DAI values ​​in DCI-1, DCI-2, ..., DCI-6 are 1, 2, 3, 4, 1, 2 respectively. Thus, after the terminal receives DCI-1, DCI-2, DCI-3, and DCI-4, the DAI cycle count is 0, while after receiving DCI-5 and DCI-6, the DAI cycle count is 1. If a terminal misses a DCI, such as missing DCI-1 and DCI-2, the terminal can determine the number of unreceived DCIs by the number of DAI cycles, the number of DCIs received, and the DAI value in the last received DCI (the value of C-DAI in DCI-6).

[0128] It should also be known that the number of DCIs received and the number of DAI cycles obtained by the terminal in step 101 are as follows: For TB-based transmissions, these are the number of DCIs detected out of the M PDCCH detection opportunities corresponding to the HARQ-ACK carried by the PUCCH for scheduling TB-based PDSCH transmissions, or for instructing SPS PDSCH release, or for instructing SCell sleep, and the number of cycles of the DAI value contained in the DCI. For CBG-based transmissions, these are the number of DCIs detected out of the M PDCCH detection opportunities corresponding to the HARQ-ACK carried by the PUCCH for scheduling CBG-based PDSCH transmissions, and the number of cycles of the DAI value contained in the DCI.

[0129] Furthermore, considering that the serving cell of the terminal may be configured (or configured) to perform transport block (TB) based transmission, or it may also be configured (or configured) to perform code block group (CBG) based transmission, in this embodiment, optionally, when the serving cell of the terminal is not configured to perform code block group (CBG) based transmission, the number of DCIs not received is the number M1 of DCIs scheduled for transport block (TB) based transmission that the terminal has not received; or,

[0130] When at least one cell of the serving cell of the terminal is configured with CBG-based transmission, the number of DCIs not received is related to the number M1 of DCIs not received by the terminal and scheduled with TB-based transmission, and the number M2 of DCIs not received by the terminal and scheduled with CBG-based transmission.

[0131] Where M1 is an integer greater than or equal to 0, and M2 is an integer greater than or equal to 0.

[0132] In other words, if none of the terminal's serving cells are configured for CBG-based transmission, the number of DCIs not received by the terminal is the number of DCIs scheduled for TB-based transmission that the terminal has not received (M1). If at least one of the terminal's cells is configured for CBG-based transmission, the number of DCIs not received by the terminal is related to the number of DCIs scheduled for TB-based transmission that the terminal has not received (M1) and the number of DCIs scheduled for CBG-based transmission that the terminal has not received (M2). That is, the calculation of the PUCCH power control parameter formula is based on the values ​​of two parameters, M1 and M2. In one implementation, the number of DCIs not received includes both M1 and M2, but is not limited to M1+M2, or either M1 or M2.

[0133] Optionally, in this embodiment, the number of DCIs that the terminal did not receive and that were scheduled based on TB transmissions is determined by the formula... Calculated;

[0134] Specifically, when the terminal is configured to transmit on a serving cell... It is the last scheduled TB-based PDSCH transmission detected by the terminal in M ​​physical downlink control channel (PDCCH) monitoring opportunities, or an indication of semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release, or an indication of the C-DAI value in the DCI of the secondary cell SCell during sleep.

[0135] If the terminal is configured to transmit on at least two serving cells, and if the terminal does not detect any DCI containing T-DAI during the first PDCCH monitoring opportunity, then It is the C-DAI value in the last DCI detected by the terminal during the first PDCCH monitoring opportunity; if the terminal detects at least one DCI containing T-DAI during the first PDCCH monitoring opportunity, then It is the T-DAI value in the DCI detected by the terminal in the first PDCCH monitoring opportunity; if the terminal does not detect any scheduled TB-based PDSCH transmission, or indicates SPS PDSCH release, or indicates SCell sleep in the M PDCCH monitoring opportunities, then Wherein, the first PDCCH monitoring opportunity is the last of the M PDCCH monitoring opportunities to detect the scheduling of TB-based PDSCH transmission, or to indicate the release of SPS PDSCH, or to indicate the DCI of SCell sleep.

[0138] It refers to the number of PDSCH transmissions scheduled based on TB, or the number of SPS PDSCH releases, or the number of DCIs that indicate SCell sleep, detected in the M PDCCH monitoring opportunities of the c1th serving cell; c1 is greater than or equal to 0 and less than or equal to 0. Integers; This refers to the number of serving cells that the base station configures for the terminal;

[0139] The M PDCCH monitoring opportunities are the PDCCH monitoring opportunities corresponding to the HARQ-ACK codebook carried by the PUCCH, where M is an integer greater than or equal to 1.

[0140] Here, if the terminal does not detect any scheduled TB-based PDSCH transmissions, or indicates SPS PDSCH release, or indicates SCell sleep DCI during the M PDCCH monitoring opportunities in the c1 serving cell, then

[0141] Optionally, the number of DCIs that the terminal did not receive and that were scheduled for CBG transmission is determined by the formula... Calculated;

[0142] Specifically, when the terminal is configured to transmit on a serving cell... It is the C-DAI value in the DCI of the last scheduled CBG-based PDSCH transmission detected by the terminal in M ​​PDCCH monitoring opportunities; when the terminal is configured to transmit on at least two serving cells. It is the T-DAI value in the DCI of the last scheduled CBG-based PDSCH transmission detected by the terminal in M ​​PDCCH monitoring opportunities;

[0146] The M PDCCH monitoring opportunities are the PDCCH monitoring opportunities corresponding to the HARQ-ACK codebook carried by the PUCCH, where M is an integer greater than or equal to 1.

[0147] Here, similarly, if the terminal does not detect any DCI format for scheduling CBG-based PDSCH transmissions during the M PDCCH monitoring opportunities in the c2th serving cell, then

[0148] After determining the number of unreceived DCIs, step 103 is executed to determine the control parameters for PUCCH power. As can be seen from the above, when the terminal's serving cell is not configured for CBG-based transmission, the number of unreceived DCIs is only the number of DCIs that the terminal has not received and that are scheduled for TB-based transmission. Therefore, optionally, in this embodiment, step 103 includes:

Therefore, optionally, in this embodiment, step 103 includes:

[0156] When at least one cell of the serving cell of the terminal is configured to transmit based on CBG, the terminal determines the control parameters of PUCCH power based on M1 and M2.

[0157] Optionally, the terminal determines the control parameters for PUCCH power based on M1 and M2, including:

[0158] The terminal uses formula n HARQ-ACK =n HARQ-ACK,TB +n HARQ-ACK,CBG The control parameter n of PUCCH power is calculated. HARQ-ACK ;

Integers; M is the number of serving cells configured by the base station for the terminal; M is the number of PDCCH monitoring opportunities in the PDCCH monitoring opportunity set corresponding to the HARQ-ACK codebook carried by the PUCCH, and M is an integer greater than or equal to 1.

[0160]

[0161] yes Each service area corresponds to The maximum value in, This refers to the number of transmission codewords configured for the c2th serving cell. This is the maximum number of CBGs configured for the c2th serving cell; It is the number of CBGs contained in the PDSCH used for scheduling DCI scheduling based on CBG transmission detected by the terminal during the m-th PDCCH detection time of the c2-th serving cell, and the terminal transmits the corresponding HARQ-ACK on the PUCCH; c2 is greater than or equal to 0 and less than or equal to Integers; It is the number of serving cells that the base station configures for the terminal to use CBG transmission; m is an integer greater than or equal to 0 and less than or equal to M-1.

[0162] The application of the embodiments of the present invention is illustrated below with specific scenarios:

[0163] Scenario 1, with Figure 2As shown, assuming the terminal is configured with a serving cell and uses single-codeword transmission, the DCI contains 2 bits of C-DAI. The base station sends a total of 6 DCIs for scheduling PDSCH, namely DCI-1, DCI-2, ..., DCI-6, and for these 6 DCIs, the base station instructs that their corresponding HARQ-ACKs be fed back on PUCCH-1. However, the terminal only receives DCI-4 and DCI-6, as shown in Table 1 below:

[0164] Table 1

[0165] DCI DCI-1 DCI-2 DCI-3 DCI-4 DCI-5 DCI-6 C-DAI 1 2 3 4 1 2 j1 0 0 0 0 1 1 Terminal receiving N N N Y N Y

[0166] at this time, The value of C-DAI in DCI-6 (the last received DCI), i.e. For 2, T D =4, j1=1. Therefore, the terminal determines the number of DCIs sent by the base station as follows: Since the terminal only receives DCI-4 and DCI-6, Therefore, according to The calculation yields M1 = 6 - 2 = 4, which matches the actual situation.

[0167] Then, based on According to Determine the control parameter n for obtaining PUCCH power. HARQ-ACK =6.

[0168] Scenario 2: Assume the terminal is configured with two serving cells. Serving cell 1 is configured for TB-based dual-codeword transmission, and serving cell 2 is configured for CBG-based single-codeword transmission, with 4 CBGs. The DCI contains 2 bits of C-DAI. The base station transmits a total of 7 DCIs for scheduling TB-based PDSCH transmission on serving cell 1, namely TBDCI-1, TBDCI-2, TBDCI-4, TBDCI-5, TBDCI-6, TBDCI-7, and TBDCI-8; and transmits a total of 1 DCI for scheduling TB-based PDSCH transmission, namely TBDCI-3, and 6 DCIs for scheduling CBG-based PDSCH transmission on serving cell 2 (namely CBGDCI-1, TBDCI-3, CBGDCI-2, CBGDCI-3, CBGDCI-4, CBGDCI-5, and CBGDCI-6). Of these 14 DCIs, the corresponding HARQ-ACK feedbacks are transmitted on the same PUCCH. However, the UE receives TBDCI-1 / 2 / 5 / 8 on serving cell 1 and CBGDCI-2 / 6 on serving cell 2, as shown in Table 2 below:

[0169] Table 2

[0170]

[0171]

[0172] First, through Depend on The value of C-DAI in the last received TB DCI, i.e. For 4, T D =4, j1=1. Therefore, the terminal determines the number of DCIs sent by the base station as follows: Since the terminal received TBDCI-1 / 2 / 5 / 8, Therefore, M1 = 8 - 4 = 4, which matches the actual situation.

[0173] pass Depend on The value of C-DAI in the last received CBGDCI, i.e. For 2, T D =4, j2=1. Therefore, the terminal determines the number of DCIs sent by the base station as follows: Since the terminal received CBGDCI-2 / 6, Therefore, according to M2 = 6 - 2 = 4, it matches the actual situation.

[0174] Then, using formula n HARQ-ACK =n HARQ-ACK,TB +n HARQ-ACK,CBG The control parameter n of PUCCH power is calculated. HARQ-ACK .

[0175] in, In this scenario, Then n can be determined HARQ-ACK,TB =4*2+6=14.

[0176] In this scenario, Then n can be determined HARQ-ACK,CBG =4*4+7=23.

[0177] Therefore, n HARQ-ACK 14 + 23 = 37. The terminal determines the PUCCH transmission power according to the control parameter of 37 for PUCCH power.

[0178] In summary, the method of this embodiment of the invention allows the terminal to determine the control parameters of PUCCH power based on the number of DAI cycles, the number of DCI receptions, and the DAI value in the last received DCI. Subsequently, feedback information is transmitted according to the PUCCH power determined by these control parameters. Since the determined PUCCH power will not be less than the power required for actual PUCCH transmission, the problem of reduced PUCCH transmission performance is avoided.

[0184] When at least one cell of the serving cell of the terminal is configured with CBG-based transmission, the number of DCIs not received is related to the number M1 of DCIs not received by the terminal and scheduled with TB-based transmission, and the number M2 of DCIs not received by the terminal and scheduled with CBG-based transmission.
