Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and related apparatus for transmitting response information based on an uplink control channel. Background Technology

[0002] Base stations transmit directional beams to achieve network coverage, and user terminals (UEs) located within this coverage area can communicate with the base station. Therefore, network coverage is a key factor in communication networks. Base station network coverage refers to the transmission range of the base station's signal source to enable wireless access for user terminals. To support the normal operation of the uplink / downlink shared channel, user terminals need to send control information related to uplink and downlink data transmission to the base station. This uplink data transmission control information is transmitted through the Physical Uplink Control Channel (PUCCH). Currently, enhancing the coverage of the Physical Uplink Control Channel is an important research direction in the field of communications.

[0003] In 5G New Radio (NR), user terminals access the communication network through a random access procedure with the base station. During this procedure, the hybrid automatic repeat request-acknowledgment (HARQ-ACK) message 4 (Msg4) is carried by the PUCCH. During wireless signal transmission, signal power experiences spatial diffusion and absorption, resulting in path loss. In current 5G NR, with significant path loss and limited transmit signal power from the user terminal, the base station may fail to correctly detect the PUCCH, thus preventing the base station from responding to message Msg4 during the random access procedure and ultimately hindering the user terminal's access. Summary of the Invention

[0040] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0042] Please see Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the method for transmitting response information based on the uplink control channel according to this application.

[0043] Step S11: The number of transmissions of the transmission response information sent by the base station to the user terminal is configured by the base station through the system information block.

[0044] In one embodiment, the response information is a hybrid automatic repeat request-acknowledgement (HARQ-ACK) for message 4 (Msg4) during the random access process. During the random access process, the hybrid automatic repeat request-acknowledgement (HARQ-ACK) for message 4 (Msg4) is carried by PUCCH. In this embodiment, the response information is represented as PUCCH for Msg4 HARQ ACK.

[0045] In one embodiment, the base station configures the number of transmissions of PUCCH for Msg4 HARQ ACK in the System Information Block (SIB).

[0046] The System Information Block (SIB) includes System Information Block 1 (SIB1) and other system information (OSI). In an optional embodiment, the base station can configure the number of transmissions in SIB1 and broadcast it to the user terminal, or it can configure the number of transmissions in the OSI and broadcast it to the user terminal.

[0047] In one embodiment, the field representing the number of times the response information has been transmitted is represented as:

[0048] PUCCH-Repetitionfactor-for-Msg4-HARQ-ACK ENUMERATED{n2,n4,n8}.

[0049] Where {n2,n4,n8} represents the number of transmissions, and the possible values ​​are one of {2, 4, 8}.

[0050] When the PUCCH-Repetitionfactor-for-Msg4-HARQ-ACK field is not configured, the default number of response message transmissions is 1. When the PUCCH-Repetitionfactor-for-Msg4-HARQ-ACK field is configured to 2, the number of response message transmissions is 2. When the PUCCH-Repetitionfactor-for-Msg4-HARQ-ACK field is configured to 4, the number of response message transmissions is 4.

[0051] Step S12: The user terminal transmits the response information to the base station based on the number of transmissions.

[0052] After receiving the number of transmissions sent by the base station, the user terminal transmits response information to the base station based on the number of transmissions.

[0053] For example, if the user terminal receives the information PUCCH-Repetitionfactor-for-Msg4-HARQ-ACKENUMERATED{2}, then the transmission count is determined to be 2, and the user terminal will transmit the response information to the base station twice. Similarly, if the user terminal receives the information PUCCH-Repetitionfactor-for-Msg4-HARQ-ACKENUMERATED{4}, then the transmission count is determined to be 4, and the user terminal will transmit the response information to the base station twice. As another example, if the user terminal receives the information PUCCH-Repetitionfactor-for-Msg4-HARQ-ACK ENUMERATED{1}, then the transmission count is determined to be 1, and the user terminal will transmit the response information to the base station once.

[0054] In this embodiment of the application, the base station configures the number of transmissions of the response information through the system information block and sends the number of transmissions to the user terminal. The user terminal transmits the response information to the base station based on the number of transmissions to increase the probability that the base station detects the response information carried by the PUCCH, thereby completing the response of the random access procedure Msg4.

[0055] In an optional embodiment, even with path loss, the base station can still detect the response information carried by the PUCCH when the user terminal sends it once, and the base station can be configured to transmit once.

[0056] Please see Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of the method for transmitting response information based on the uplink control channel according to this application.

[0057] Step S21: The number of transmissions of the transmission response information sent by the base station to the user terminal is configured by the base station through the system information block.

[0058] For the specific implementation method of this step, please refer to Figure 1 Step S11, as described in the embodiments, will not be repeated here.

[0059] Step S22: The user terminal confirms whether it has the ability to repeatedly transmit based on the number of transmissions, wherein the number of transmissions is greater than 1.

[0060] In one optional embodiment, the user terminal confirms the number of times it supports transmitting response information based on parameter information; and confirms whether the user terminal has the ability to repeatedly transmit based on the confirmed number of transmissions and the number of transmissions received from the base station.

[0061] Repeatable transmission capability refers to the ability of a user terminal to repeatedly send response information to the base station. Understandably, if the base station is configured to transmit only one number of times, it means the user terminal does not need to repeatedly transmit the response information. If the base station is configured to transmit more than one number of times, it means the user terminal needs to repeatedly transmit the response information.

[0062] The parameter information may include the user terminal's memory utilization, signal transmission power, processor parameters, etc., and is not specifically limited. For example, if the remaining memory is insufficient to cache physical layer data for repeated transmissions that are greater than or equal to the predetermined duration, then repeated transmissions cannot be performed; if the processor's processing capacity is insufficient to complete the processing required for repeated transmissions within the required time, then repeated transmissions cannot be performed.

[0063] In one embodiment, if the number of transmissions confirmed by the user terminal is 1, or if the number of transmissions confirmed is different from the number of transmissions sent by the base station, it indicates that the user terminal does not have the ability to repeatedly transmit. If the number of transmissions confirmed by the user terminal is greater than 1 and is the same as the number of transmissions sent by the base station, it is confirmed that the user terminal has the ability to repeatedly transmit.

[0064] It should be noted that repeated transmission requires consensus between the user terminal and the base station; that is, the number of transmissions confirmed by the user terminal must be the same as the number of transmissions configured by the base station. If the number of transmissions confirmed by the user terminal is different from the number of transmissions configured by the base station, then the user terminal is determined to lack the ability to repeatedly transmit. It is understood that the "repeated transmission capability" in this application refers to the repeated transmission capability configured by the base station. If the user terminal can transmit with the number of transmissions configured by the base station (the number of transmissions is greater than 1), then the user terminal has the ability to repeatedly transmit; if the user terminal cannot transmit with the number of transmissions configured by the base station, then the user terminal does not have the ability to repeatedly transmit.

[0065] Step S23: If the user terminal has the capability to retransmit, the user terminal sends a first feedback message to the base station. The first feedback message is used to indicate that the user terminal has the capability to retransmit.

[0066] Understandably, if the number of transmissions confirmed by the user terminal is greater than 1 and the same as the number of transmissions received from the base station, then the user terminal is confirmed to have the capability for repeated transmissions. At this point, the user terminal sends a first feedback message to the base station. This first feedback message includes confirmation that the user terminal has the capability for repeated transmissions, informing the base station so that the base station can prepare to receive response information based on the number of transmissions. Then, the user terminal transmits the response information to the base station based on the number of transmissions.

[0067] In one embodiment, if the number of transmissions confirmed by the user terminal is 1, it indicates that the user terminal does not have the capability for repeated transmissions. The user terminal then sends a second feedback message to the base station, informing the base station that it lacks the capability for repeated transmissions. In this case, the user terminal sends a response message to the base station once. Optionally, if the number of transmissions confirmed by the user terminal is different from the number of transmissions received from the base station, the user terminal does not send feedback information to the base station.

[0068] In practical applications, the number of transmissions confirmed by the user terminal is determined based on its own parameter information, such as memory utilization, signal transmission power, and processor parameters. If the user terminal's own parameter information changes, the number of transmissions confirmed will also change. If the changed number of transmissions differs from the number of transmissions configured by the base station, no feedback information will be sent to the base station. Understandably, if the changed number of transmissions is greater than 1 and the same as the number of transmissions configured by the base station, a second feedback information will be sent to the base station to report the repeated transmission capability and perform repeated transmissions.

[0069] In one embodiment, the first or second feedback information transmitted by the user terminal is transmitted via message 3 (Msg3) during the random access procedure. Specifically, Msg3 is transmitted via PUSCH (Physical Uplink Shared Channel), and the information transmitted by Msg3 includes MAC CE (media access control control element) signaling or RRC (radio resource control) signaling.

[0070] For example, when transmitting the first or second feedback information via Msg3's MAC CE signaling, the specific form of the first or second feedback information is as follows:

[0071] PUCCH-Repetitioncapabilityindicator-for-Msg4-HARQ-ACK 1bit,

[0072] This field is 1 bit. A value of "1" indicates the first feedback message, and a value of "0" indicates the second feedback message. The first feedback message indicates that the user terminal has the capability to retransmit data, and the second feedback message indicates that the user terminal does not have the capability to retransmit data.

[0073] For example, when transmitting the first or second feedback information via Msg3's MAC CE signaling, the specific form of the first or second feedback information is as follows:

[0074] PUCCH-Repetitioncapabilityindicator-for-Msg4-HARQ-ACK 2bit

[0075] When this field uses 2 bits to indicate information, its 2-bit value indicates a value from the set of repeated transmission counts {1, 2, 4, 8}. If the value indicated by the field is the same as the number of transmissions configured by the base station, it indicates the first feedback information; if the value indicated by the field is "1", it indicates the second feedback information. When the value indicated by the field is neither the same as the number of transmissions configured by the base station nor "1", it can be reserved for transmitting other information. Alternatively, only 1 bit of the LSB (Least Significant Bit) or 1 bit of the MSB (Most Significant Bit) of this field can be used to indicate information. If its value is "1", it indicates the first feedback information; if its value is "0", it indicates the second feedback information.

[0076] For example, when transmitting the first or second feedback information via Msg3's RRC signaling, the specific form of the first or second feedback information is as follows:

[0077] PUCCH-Repetitioncapabilityindicator-for-Msg4-HARQ-ACK ENUMERATED{Enable,Disable}.

[0078] If its value is "Enable", it indicates the first feedback message; if its value is "Disable", it indicates the second feedback message.

[0079] For example, when transmitting the first or second feedback information via Msg3's RRC signaling, the specific form of the first or second feedback information is as follows:

[0080] PUCCH-Repetitioncapabilityindicator-for-Msg4-HARQ-ACK ENUMERATED{n1,n2,n4,n8}

[0081] If the value of this field is the same as the number of transmissions configured by the base station, it indicates the first feedback information; if the value of this field is "n1", it indicates the second feedback information. When the value of this field is neither the same as the number of transmissions configured by the base station nor "n1", it can be reserved for transmitting other information.

[0082] Step S24: The user terminal transmits the response information to the base station based on the number of transmissions.

[0083] If the user terminal sends the first feedback information to the base station, the user terminal will repeatedly transmit the response information to the base station based on the number of transmissions. If the user terminal sends the second feedback information to the base station, the user terminal will transmit the response information to the base station once based on the number of transmissions.

[0084] In this embodiment, the number of transmissions confirmed by the user terminal and the number of transmissions configured by the base station are used to determine whether the user terminal has the function of repeated transmission. If it has the function of repeated transmission, the response information is transmitted to the base station according to the configured number of repeated transmissions, thereby increasing the probability that the base station detects the response information carried by the PUCCH, and thus completing the response of the random access procedure Msg4.

[0085] Please see Figure 3 The following is a flowchart illustrating a third embodiment of the method for transmitting response information in this application. The transmission method can be as follows.

[0086] Step 31: The number of transmissions the user terminal receives from the base station's transmission response information is configured by the base station through the system information block.

[0087] For the specific implementation method of this step, please refer to Figure 1 Step S11, as described in the embodiments, will not be repeated here.

[0088] Step 32: The user terminal confirms whether it has the ability to repeatedly transmit based on the number of transmissions, wherein the number of transmissions is greater than 1.

[0089] For the specific implementation method of this step, please refer to Figure 2 Step S22, as described in the embodiments, will not be repeated here.

[0090] Step S33: If the user terminal has the capability for repeated transmission, the user terminal confirms whether the user terminal has a need for repeated transmission.

[0091] When it is determined that the user terminal has the capability for repeated transmission, it is further confirmed whether the user terminal has a need for repeated transmission. In one embodiment, the coverage capability of the uplink signal can be inferred from the signal strength of the downlink signal. For example, if the coverage capability of the uplink signal does not meet the preset requirements, it is confirmed that the user terminal has a need for repeated transmission. The downlink signal may be a demodulation reference signal of a synchronization signal block or a reference signal of a synchronization signal, etc.

[0092] In one optional embodiment, if the power of the downlink signal received by the user terminal is less than the signal strength threshold, or if the base station has not configured a signal strength threshold (i.e., the user terminal has not received the signal strength threshold configured by the base station), then the user terminal determines that it has a need for repeated transmission. Here, the signal strength threshold is the signal strength threshold issued by the base station.

[0093] For example, the downlink signal power received by the user terminal can be the power of the demodulation reference signal (DMRS) of the synchronization signal block (SSB) or the reference signal receiving power (RSRP) of the synchronization signal.

[0094] It should be noted that SSB includes synchronization signals and broadcast signals. The synchronization signals include the primary synchronization signal (PSS) and the secondary synchronization signal (SSS), while the broadcast signals include Physical Broadcast Channel data (PBCH Data) and PBCH DMRS.

[0095] Step S34: If the user terminal has a need for repeated transmission, the user terminal sends a first feedback message to the base station. The first feedback message is used to indicate that the user terminal has the ability to repeat transmission.

[0096] Step S35: If the user terminal does not have a need for repeated transmission, the user terminal sends a second feedback message to the base station. The second feedback message is used to indicate that the user terminal does not have the ability to repeat transmission.

[0097] If it is determined that the user terminal has a repeat transmission function and a repeat transmission requirement, a first feedback message is sent to the base station, and a response message is transmitted to the base station based on the number of transmissions. If the user terminal does not have a repeat transmission requirement, a second feedback message is sent to the base station. In this embodiment, the method of sending the first and second feedback messages to the base station is the same as... Figure 2The descriptions in the Chinese embodiments are the same and will not be repeated here.

[0098] Understandably, if the power of the downlink signal received by the user terminal is greater than or equal to the signal strength threshold, then the coverage capability of the PUCCH is determined to meet the preset conditions, and there is no need for repeated transmission.

[0099] Step S36: The user terminal transmits the response information to the base station based on the number of transmissions.

[0100] In this embodiment, the number of transmissions confirmed by the user terminal and the number of transmissions configured by the base station are used to determine whether the user terminal has the function of repeated transmission. If it has the function of repeated transmission, it is further confirmed whether there is a transmission requirement. If there is a transmission requirement, the response information is transmitted to the base station according to the configured number of repeated transmissions, thereby increasing the probability that the base station detects the response information carried by the PUCCH, and thus completing the response of the random access procedure Msg4.

[0101] Please see Figure 4 , Figure 4 This is a schematic diagram of an embodiment of the apparatus for transmitting response information based on the uplink control channel according to this application, specifically including: a receiving module 41 and a transmitting module 42. The receiving module 41 is used to receive the number of transmissions of the response information sent by the base station, the number of transmissions being configured by the base station through a system information block; the transmitting module 42 transmits the response information to the base station based on the number of transmissions.

[0102] In one embodiment, please refer to Figure 5 The device for transmitting response information also includes a capability confirmation module 43 and a feedback module 44. The capability confirmation module 43 is used to confirm whether the user terminal has the capability of repeated transmission based on the number of transmissions, wherein the number of transmissions is greater than 1. If the capability confirmation module confirms that the user terminal has the capability of repeated transmission, the feedback module 44 is used to send first feedback information to the base station. The first feedback information is used to indicate that the user terminal has the capability of repeated transmission.

[0103] In one embodiment, the capability verification module 43 verifies the number of transmissions supporting the transmission response information based on parameter information; and verifies whether the user terminal has the capability for repeated transmission based on the verified number of transmissions and the number of transmissions sent by the base station. Specifically, if the verified number of transmissions is greater than 1 and is the same as the number of transmissions sent by the base station, the capability verification module 43 determines that the user terminal has the capability for repeated transmission; if the verified number of transmissions is equal to 1 or is different from the number of transmissions sent by the base station, the capability verification module 43 determines that the user terminal does not have the capability for repeated transmission.

[0104] In one embodiment, please refer to Figure 6The device for transmitting response information further includes a capability confirmation module 43, a demand confirmation module 45, and a feedback module 44. The capability confirmation module 43 is used to confirm whether the user terminal has the capability for repeated transmission based on the number of transmissions, wherein the number of transmissions is greater than 1. If the capability confirmation module 43 confirms that the user terminal has the capability for repeated transmission, the demand confirmation module 45 confirms whether the user terminal has a demand for repeated transmission. If the demand confirmation module 45 confirms that the user terminal has a demand for repeated transmission, the feedback module 44 sends first feedback information to the base station, which indicates that the user terminal has the capability for repeated transmission; if the demand confirmation module 45 confirms that the user terminal does not have a demand for repeated transmission, the feedback module 44 sends second feedback information to the base station, which indicates that the user terminal does not have the capability for repeated transmission.
