[0055] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0056] For traditional unicast transmission, the Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH) are typically scrambled using the Cell Radio Network Temporary Identifier (C-RNTI) and are usually used for a single UE. The corresponding HARQ-ACK feedback is usually based on ACK / NACK, and the UE needs to feed back HARQ-ACK on the PUCCH. The PUCCH power control is based on a mechanism of open-loop slow power control combined with fast power compensation. The target received power P0 and the reference signal used for path loss measurement in the open-loop slow power control can be flexibly set. Fast power compensation is mainly implemented through closed-loop power control commands. Specifically, for adjusting the uplink transmit signal power through the TPC command carried in the DCI, the PUCCH closed-loop power control TPC command uses an cumulative adjustment method. That is, based on the original transmit power, the adjustment value corresponding to the TPC command is accumulated and summed for use in the next uplink signal transmission.

[0057] In practical applications, the network configures the starting positions of the TPC command fields for each UE, namely tpc-IndexPCell and tpc-IndexPUCCH-Scell, corresponding to the primary cell (PCell) or PUCCH-secondary cell (PUCCH-SCell). Each TPC Command field is 2 bits in size. If the UE supports two PUCCH power control adjustment states (via twoDifferentTPC-Loop-PUCCH) and the UE is configured with two PUCCH power control adjustment states (via twoPUCCH-PC-AdjustmentStates), a closed loopindex field (indicating 0 or 1) will be appended after the TPC Command field.

[0058] However, for multicast transmission, the PDCCH and PDSCH corresponding to the initial transmission are usually scrambled with G-RNTI and are sent to a group of users. They can be received by all users in a multicast broadcast service (MBS) group. Therefore, if the scheduling DCI of PDCCH and PDSCH carries a TPC command, it may be received by a group of users. Different users may have different power adjustment requirements due to different channel conditions. Therefore, the power adjustment of each terminal should be different.

[0059] Based on this, in various embodiments of this application, the network side sends an indication message to the terminal, instructing the terminal to use independent TPC adjustment for the PUCCH carrying HARQ-ACK multicast PTM transmission.

[0060] The solution provided in this application uses independent TPC adjustment for HARQ-ACK feedback in multicast transmission to meet the power adjustment requirements of different terminals, thus achieving more efficient HARQ-ACK feedback for multicast transmission.

[0061] This application provides an information indication method applied to a terminal, such as... Figure 1 As shown, the method includes:

[0062] Step 101: Receive the first information sent by the network side, the first information indicating that the PUCCH carrying the HARQ feedback information of PTM transmission should be adjusted with an independent TPC value.

[0063] In practical applications, the terminal can be referred to as a UE or a user.

[0064] The first information indicates that an independent TPC value is used to adjust the PUCCH carrying HARQ feedback information for PTM transmission. This can also be understood as the first information indicating that an independent TPC command is used for the PUCCH carrying HARQ feedback information for PTM transmission.

[0065] In practical applications, the terminal can adjust the uplink transmit signal power using the TPC command carried in DCI format 1_0 / 1_1 / 1_2 or DCI format 2_2. The closed-loop power control TPC command of PUCCH uses a cumulative adjustment method, that is, based on the original transmit power, the adjustment value corresponding to the TPC command is accumulated and summed for the next uplink signal transmission. Here, DCI format 1_0 / 1_1 / 1_2 is UE-specific, and the TPC command in it is used to adjust the PUCCH uplink transmit power of that UE. For DCI format 2_2, it can be used for a group of UEs, with the scrambling code TPC-PUCCH-RNTI, indicating the PUCCH transmit power control command sent by each UE in the group on a certain carrier set.

[0066] On the other hand, for multicast transmission, different terminals may have different power adjustment requirements due to different channel conditions. Therefore, DCI format 2_2 can be enhanced to support the transmission of PUCCH for HARQ-ACK in multicast transmission, that is, the TPC command of PUCCH for multicast transmission of HARQ-ACK can be sent using DCI format 2_2.

[0067] Based on this, in one embodiment, the specific implementation of step 101 may include:

[0068] The network side receives the DCI sent by the network side, the DCI carries the first information, and the DCI is in DCI format 2_2.

[0069] In practical applications, a new field can be added to the DCI to indicate that the TPC value indicated by the TPC Commandfield in the DCI is applied to the PUCCH carrying HARQ-ACK for multicast transmission.

[0070] Based on this, in one embodiment, the first information indicates that the TPC command carried by the DCI is applied to the PUCCH carrying the HARQ feedback information of the PTM transmission.

[0071] For example, an indicator field (e.g., with a value of 0 or 1) is added after the TPC Command field or the closed loop index field. This indicator field is used to indicate that the TPC indicated by the TPC Command field is applied to the PUCCH carrying HARQ-ACK for multicast PTM transmission. For example, a value of 1 indicates that the TPC Command field is applied to the PUCCH transmission carrying HARQ-ACK for multicast PTM transmission, and a value of 0 indicates that the TPC Command field is applied to other PUCCH transmissions.

[0072] The TPC value can also be called the TPC command value, TPC adjustment value, or TPC adjustment amount, etc., and this application embodiment does not limit it in this way.

[0073] In practical applications, a TPC command field can be added to the existing DCI format, such as the second TPC command field. This second TPC command field is applied to the PUCCH that carries HARQ-ACK for multicast PTM transmission.

[0074] Based on this, in one embodiment, the DCI carries a first TPC command, and the second TPC command corresponding to the first information is applied to the PUCCH carrying the HARQ feedback information transmitted by the PTM.

[0075] The first TPC command (corresponding to the second TPC Command field) is applied to the PUCCH of the HARQ feedback information transmitted via unicast.

[0076] For example, a second TPC Command field can be added after the TPC Command field or the closed loop index field. This second TPC Command field is applied to the PUCCH carrying HARQ-ACK for multicast PTM transmission.

[0077] In the above implementation, the network sends two types of TPC commands to the terminal: a TPC command for the PUCCH used for HARQ feedback information in unicast transmission and a TPC command for the PUCCH used for HARQ feedback information in multicast transmission.

[0078] In practical applications, the second TPC Command field and the existing TPC Command field in the DCI format (which can be referred to as the first TPC Command field) can be encoded and indicated independently, meaning the first information indicates the TPC value of the second TPC command. For example, the mapping relationship between the value of the second TPC Command field and the power adjustment amount can be shown in Table 1.

[0079] Second TPC Command Field <![CDATA[Accumulatedδ PUCCH,b,f,c [dB]]]> 0 -1 1 0 2 1 3 3

[0080] Table 1

[0081] In practical applications, the second TPC Command field can also be differentially indicated with the first TPC Command field. That is, the power adjustment amount corresponding to the value of the second TPC Command field represents the difference relative to the power adjustment amount corresponding to the first TPC Command field. In other words, the first information indicates the difference between the TPC value of the second TPC command and the TPC value of the first TPC command. For example, the mapping relationship between the value of the second TPC Command field and the difference is shown in Table 2.

[0082]

[0083] Table 2

[0084] As can be seen from the above description, the first information sent by the network to the terminal is configuration information, which configures the terminal to use independent TPC adjustments for the PUCCH carrying multicast PTM transmission.

[0085] For HARQ-ACK feedback in multicast transmission, it can be HARQ-ACK feedback based on ACK / NACK. That is, the HARQ feedback information in the PTM transmission includes HARQ-ACK feedback information based on ACK / NACK. In other words, for the received multicast service, the terminal sends ACK or NACK feedback to the network.

[0086] For HARQ-ACK feedback in multicast transmission, it can also be based on NACK-only HARQ-ACK feedback. That is, the HARQ feedback information in the PTM transmission includes: NACK-only HARQ-ACK feedback information. That is, for the received multicast service, the terminal only feeds back NACK to the network, and does not feed back ACK for correctly received data.

[0087] In practical applications, the network side can configure the HARQ-ACK feedback for terminal multicast transmission to be either ACK / NACK based or NACK-only. For example, the HARQ-ACK feedback for terminal multicast transmission can be configured via Radio Resource Control (RRC) signaling or DCI to be either ACK / NACK based or NACK-only.

[0088] In practical applications, for a terminal, the network may use a wider receive beam to receive the PUCCH transmissions corresponding to HARQ-ACK based on ACK / NACK for multicast transmissions of that terminal, while using a narrower receive beam to receive the PUCCH transmissions corresponding to unicast transmissions of that terminal. Alternatively, the base station may use a wider receive beam to receive the PUCCH transmissions corresponding to HARQ-ACK based on NACK-only for multicast transmissions of that terminal (because a group of MBS users may use the same PUCCH resource for HARQ-ACK feedback based on NACK-only), while using a narrower receive beam to receive other types of PUCCH transmissions.

[0089] Upon receiving the first information, the terminal can use the first information to adjust the power of the PUCCH that carries the HARQ feedback information transmitted by the PTM.

[0090] Based on this, in one embodiment, such as Figure 1 As shown, the method may further include:

[0091] Step 102: Using the first information, determine the TPC value of the PUCCH that carries the HARQ feedback information transmitted by the PTM;

[0092] Step 103: Using the determined TPC value, adjust the power of the PUCCH that carries the HARQ feedback information transmitted by the PTM.

[0093] In step 102, when the first information indicates that the TPC command carried by the DCI is applied to the PUCCH carrying the HARQ feedback information transmitted by the PTM, the terminal uses the TPC value of the TPC command carried by the DCI as the TPC value of the PUCCH carrying the HARQ feedback information transmitted by the PTM.

[0094] When the first information indicates the TPC value of the second TPC command, the terminal uses the TPC value of the second TPC command as the TPC value of the PUCCH of the HARQ feedback information transmitted by the PTM.

[0095] When the first information indicates the difference between the TPC value of the second TPC command and the TPC value of the first TPC command, the terminal uses the difference and the TPC value of the first TPC command to determine the TPC value of the PUCCH carrying the HARQ feedback information of the PTM transmission.

[0096] In step 103, after the terminal determines the TPC value, it can accumulate and sum the adjustment value corresponding to the TPC command based on the original transmit power, thereby adjusting the power of the PUCCH carrying the HARQ feedback information transmitted by the PTM, so as to use it for the next transmission of the PUCCH carrying the HARQ feedback information transmitted by the PTM.

[0097] For multicast transmission, the typical transmission method is PTM transmission. When the initial transmission uses PTM transmission, retransmission can use either PTM transmission or point-to-point (PTP) transmission.

[0098] Accordingly, this application also provides an information indication method, applied to a network device, specifically a base station, such as a gNB, the method comprising:

[0099] Send a first message to the terminal, the first message indicating that the PUCCH carrying HARQ feedback information for PTM transmission should be adjusted with an independent TPC value.

[0100] In practical applications, the network device needs to determine the first information first. However, the network device can determine the first information as needed, and this embodiment does not limit this determination.

[0101] In one embodiment, sending the first information to the terminal includes:

[0102] A DCI is sent to the terminal, the DCI carrying the first information, and the DCI is in DCI format 2_2.

[0103] This application also provides an information indication method, such as... Figure 2 As shown, the method includes:

[0104] Step 201: The network device sends first information to the terminal, the first information indicating that the PUCCH carrying HARQ feedback information for PTM transmission should be adjusted with an independent TPC value;

[0105] Step 202: After receiving the first information, the terminal uses the first information to determine the TPC value of the PUCCH that carries the HARQ feedback information transmitted by the PTM.

[0106] Step 203: The terminal uses the determined TPC value to adjust the power of the PUCCH that carries the HARQ feedback information transmitted by the PTM.

[0107] It should be noted that the specific processing procedures of the terminals and network devices have been detailed above and will not be repeated here.

[0108] The information indication method provided in this application embodiment involves the network sending first information to the terminal. The first information indicates that the PUCCH carrying HARQ feedback information for PTM transmission adopts independent TPC value adjustment, and the HARQ-ACK feedback for multicast transmission adopts independent TPC adjustment, so as to meet the power adjustment requirements of different terminals. In this way, more efficient HARQ-ACK feedback for multicast transmission can be achieved.
