Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly to a transmission method and terminal, network equipment, storage medium, and computer program product. Background Technology

[0002] Msg3 typically refers to "Message 3," which is used by a terminal during the handshake process with the base station to inform the terminal of its identity and request to establish a connection. Repeated transmission of Msg3 can be used to improve Msg3 coverage.

[0003] In Subband Full Duplex (SBFD) systems, uplink (UL) subbands can be configured in downlink time slots for uplink transmission, and uplink resources can also be used for random access. Since neighboring base stations can transmit downlink on SBFD symbols, the Physical Random Access Channel (PRACH) and Msg3 Physical Uplink Shared Channel (PUSCH) received by base stations on SBFD symbols suffer from cross-link interference (CLI), resulting in a degradation in Msg3PUSCH demodulation performance.

[0007] The terminal receives a signal strength parameter sent by the network device, corresponding to a first threshold and a second threshold. The first threshold is used to indicate that the terminal does not initiate a random access request or initiates the random access request on a first time domain resource. The second threshold is used to indicate that the terminal initiates the random access request on the first time domain resource or the second time domain resource. The random access request is used to request the repeated transmission of the first message.

[0008] Secondly, this application proposes a transmission method applied to a network device, the method comprising:

[0009] Configure a first threshold and a second threshold corresponding to the signal strength parameter for the terminal; the first threshold is used to indicate that the terminal does not initiate a random access request or initiates the random access request on the first time domain resource, and the second threshold is used to indicate that the terminal initiates the random access request on the first time domain resource or the second time domain resource; the random access request is used to request the repeated transmission of the first message.

[0010] Thirdly, this application proposes a terminal, the terminal comprising:

[0011] The receiving unit is configured to receive a first threshold and a second threshold corresponding to the signal strength parameters sent by the network device; the first threshold is used to instruct the terminal not to initiate a random access request or to initiate the random access request on a first time domain resource, and the second threshold is used to instruct the terminal to initiate the random access request on the first time domain resource or the second time domain resource; the random access request is used to request the repeated transmission of the first message.

[0012] Fourthly, this application provides a network device, the network device comprising:

[0013] The configuration unit is used to configure a first threshold and a second threshold corresponding to the signal strength parameter for the terminal; the first threshold is used to indicate that the terminal does not initiate a random access request or initiates the random access request on the first time domain resource, and the second threshold is used to indicate that the terminal initiates the random access request on the first time domain resource or the second time domain resource; the random access request is used to request repeated transmission of the first message.

[0014] Fifthly, this application proposes a terminal, the terminal comprising: a first processor, a first memory, and a first communication bus; the first communication bus is used to realize the connection and communication between the first processor and the first memory; when the first processor executes the running program stored in the first memory, it implements the above-described transmission method applied to the terminal.

[0016] In a seventh aspect, this application proposes a storage medium storing a computer program that, when executed by a first processor, implements the aforementioned transmission method applied to a terminal, or when executed by a second processor, implements the aforementioned transmission method applied to a network device.

[0017] Eighthly, this application proposes a computer program product, including a computer program that, when executed by a first processor, implements the above-described transmission method applied to a terminal, or, when executed by a second processor, implements the above-described transmission method applied to a network device.

It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

The terminal may be a Personal Communication Service (PCS) telephone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), or other similar devices. It may also be a smartphone, tablet, handheld computer, mobile station (MS), mobile terminal, etc. The terminal can communicate with one or more network devices via a Radio Access Network (RAN). For example, the terminal may be a mobile phone (or "cellular" phone) or a computer with a terminal. It may also be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the RAN. The terminal may also be a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, or a terminal in future network evolutions; the implementation of this application is not limited to these.

[0029] Network equipment is a device that provides wireless communication functions for terminal devices, including but not limited to: evolved Node Bs (eNBs or e-NodeBs), macro base stations, micro base stations (also known as "small base stations"), pico base stations, base transceiver stations (BTSs), base band units (BBUs), access points (APs), transmission points (TPs), or new generation Node Bs (gNodeBs) in Long-Term Evolution (LTE), New Radio (NR) systems, or Licensed-Assisted Access using Long-Term Evolution (LAA-LTE) systems.

[0030] This application provides a transmission method, such as... Figure 1 As shown, when applied to a terminal, the method may include:

[0031] S101. Receive the first threshold and the second threshold corresponding to the signal strength parameters sent by the network device; the first threshold is used to instruct the terminal not to initiate a random access request or to initiate a random access request on the first time domain resource, and the second threshold is used to instruct the terminal to initiate a random access request on the first time domain resource or the second time domain resource; the random access request is used to request the repeated transmission of the first message.

[0032] The transmission method proposed in this application is applicable to scenarios where Msg3 PUSCH is repeatedly transmitted.

[0033] In this embodiment of the application, the first message is Msg3.

[0034] In the embodiments of this application, the signal strength parameter is a parameter that characterizes the signal strength, such as the reference signal receiving power (RSRP) of the downlink pathloss reference (DPR) of the terminal.

[0035] In this embodiment of the application, the network device configures two RSRP thresholds for the terminal: a first RSRP threshold (the first threshold corresponding to the signal strength parameter) and a second RSRP threshold (the second threshold corresponding to the signal strength parameter).

[0036] It should be noted that the first RSRP threshold is used to determine whether the Msg3 repetition is effective in the random access procedure within the first time domain resource.

[0037] For example, if the RSRP of the terminal's DPR is less than the first RSRP threshold, then Msg3 will be repeatedly effective for random access procedures within the first time domain resource; if the RSRP of the terminal's DPR is not less than the first RSRP threshold, then Msg3 will not be repeatedly effective for random access procedures within the first time domain resource.

[0038] It should be noted that if the terminal determines that Msg3 repeat is not effective for random access procedures within the first time domain resource, then random access resources with Msg3 repeat set to true within the first time domain resource will be unavailable.

[0039] It should be noted that the second RSRP threshold is used to determine whether the Msg3 repetition is effective in the random access procedure within the second time domain resource.

[0040] For example, if the RSRP of the terminal's DPR is less than the second RSRP threshold, then Msg3 will be repeatedly effective for random access procedures within the first time domain resource; if the RSRP of the terminal's DPR is not less than the second RSRP threshold, then Msg3 will not be repeatedly effective for random access procedures within the first time domain resource.

[0041] It should be noted that if the terminal determines that Msg3 repeat is not effective for random access procedures within the second time domain resource, then random access resources within the second time domain resource with Msg3 repeat set to true will be unavailable.

[0042] It should be noted that the terminal transmits a specific preamble within the available random access resources (i.e., the PRACH transmission time), so that when the network device detects the specific preamble, it can determine that the corresponding terminal has sent a Msg3 retransmission request.

[0043] In this embodiment of the application, the first threshold is greater than the second threshold.

[0044] Optionally, the first threshold and the second threshold can be configured using absolute values ​​or relative values. The specific configuration method can be selected according to the actual situation, and this application embodiment does not impose specific limitations.

[0045] In this embodiment of the application, the type of the first time domain resource is a downlink symbol or a flexible symbol configured with uplink frequency domain resources, and the type of the second time domain resource is an uplink symbol.

[0046] Optionally, the first time-domain resource can be of type SBFD symbol, and the second time-domain resource can be of type Time Division Duplex (TDD) symbol. The specific type can be selected according to the actual situation, and this application embodiment does not impose specific limitations.

[0047] Understandably, considering the CLI on the SBFD symbol, if the terminal initiates random access on the SBFD Physical Random Access Channel (PRACH Occasion, PO), its Ms3 coverage performance will be worse. Therefore, the first threshold is set to be greater than the second threshold to ensure the effectiveness of the terminal's Msg3 repetition on the SFBD.

[0048] In one embodiment, when the downlink RSRP of the terminal is greater than the first RSRP threshold, the ROs of Msg3 repetition on the first time domain resource and the second time domain resource are both unavailable, and the terminal cannot request Msg3 repetition.

[0049] In another embodiment, when the downlink RSRP of the terminal is less than or equal to the first RSRP threshold and greater than the second RSRP threshold, the Msg3 repeating RO of the first time domain resource is available, and the Msg3 repeating RO of the second time domain resource is unavailable. The terminal can choose to initiate a non-Msg3 repeating random access on the second time domain resource; or it can choose to initiate a Msg3 repeating random access on the first time domain resource, or it can choose to initiate a non-Msg3 repeating random access on the first time domain resource.

[0050] In another embodiment, when the downlink RSRP of the terminal is less than the second RSRP threshold, the Msg3 repeating RO of the first time domain resource is available, and the Msg3 repeating RO of the second time domain resource is available. The terminal can choose to initiate random access with Msg3 repeating on the second time domain resource, or choose to initiate random access without Msg3 repeating on the second time domain resource; or choose to initiate random access with Msg3 repeating on the first time domain resource, or choose to initiate random access without Msg3 repeating on the first time domain resource.

[0051] In this embodiment of the application, the terminal selects, based on the comparison result between the downlink RSRP and the first threshold and the second threshold, whether to not initiate a random access request, to initiate a random access request for requesting repeated transmission of the first message on the first time domain resource, or to initiate a random access request for requesting repeated transmission of the first message on the second time domain resource.

[0052] Furthermore, in one embodiment, the terminal also receives a first transmission configuration sent by the network device. The first transmission configuration includes: a first repetition count or a first repetition count list and / or a second repetition count or a second repetition count list. The first repetition count or the first repetition count list indicates the number of times the terminal transmits the first message on the first time domain resource, and the second repetition count or the second repetition count list indicates the number of times the terminal transmits the first message on the second time domain resource. The first repetition count or the first repetition count list corresponds to the terminal initiating a random access request on the first time domain resource, and the second repetition count or the second repetition count list corresponds to the terminal initiating a random access request on the second time domain resource. The first message is transmitted according to the first transmission configuration.

[0053] In this embodiment of the application, the network device configures two sets of repetition count lists for the terminal: a first repetition count or a first repetition count list, and a second repetition count or a second repetition count list. The first repetition count or the first repetition count list is indicated by the network device. The second repetition count or the second repetition count list is the number of times the network device instructs the terminal to transmit the first message on the second time domain resource when the terminal initiates a random access request on the second time domain resource.

[0054] It should be noted that when the terminal initiates a random access request on the first time domain resource, the network device selects a repetition number from the first repetition number or the first repetition number list and instructs the terminal to indicate the number of times the terminal transmits the first message on the first time domain resource; when the terminal initiates a random access request on the second time domain resource, the network device selects a repetition number from the second repetition number or the second repetition number list and instructs the terminal to indicate the number of times the terminal transmits the first message on the second time domain resource.

[0055] It should be noted that in the scheme where the network device configures two sets of repeat count lists for the terminal, the network device can configure one RSRP threshold for the terminal to decide whether to select resource indication Msg3 repeat; or the network device can still configure two RSRP thresholds for the terminal to decide whether to select resource indication Msg3 repeat. The specific choice can be made according to the actual situation, and this application embodiment does not impose specific limitations.

[0056] It should be noted that, for scenarios where network devices configure an RSRP threshold for terminals, if the RSRP of the terminal's DPR is less than the configured RSRP threshold, then Msg3 will be repeatedly effective for random access policies within the first time domain resources and / or the second time domain resources; if the RSRP of the terminal's DPR is not less than the configured RSRP threshold, then Msg3 will not be repeatedly effective for random access policies within the first time domain resources and / or the second time domain resources.

[0057] In this embodiment, the ULgrant (uplink grant) in the Random Access Response (RAR) message or the DCI format 0_0 scrambled with the Temporary Cell-Radio Network Temporary Identifier (TC-RNTI) is used to indicate the number of repetitions of Msg3. The RAR UL grant is used for the initial transmission of Msg3, while the DCI format 0_0 scrambled with TC-RNTI is used for repeated transmissions of Msg3.

[0058] For example, if the terminal initiates random access through random access resources within the first time domain resource, then the RARUL grant or the DCI format 0_0 scrambled by TC-RNTI indicates the first repetition number or a repetition number from the list of first repetition numbers.

[0059] For example, if the terminal initiates random access through random access resources within the second time domain resources, then the RARUL grant or the DCI format 0_0 scrambled by TC-RNTI indicates the second number of repetitions or a number of repetitions from the list of second number of repetitions.

[0060] In one embodiment, the first number of repetitions or the first list of repetitions is greater than the second number of repetitions or the second list of repetitions.

[0061] It is understandable that, considering CLI on SBFD symbols, if a terminal initiates random access on SBFD RO, its Msg3 coverage performance will be worse. Therefore, if the RSRP threshold is the same, a larger number of Msg3 repetitions can be configured for SFBD symbols to compensate for the impact of CLI.

[0062] Furthermore, in another embodiment, the terminal also receives a second transmission configuration sent by the network device, the second transmission configuration including: a number of repetitions, and / or one of a first transmission mode and a second transmission mode; the first transmission mode is used to instruct the terminal to transmit a first message on a first time domain resource or on a second time domain resource, and the second transmission mode is used to instruct the terminal to transmit the first message on the first time domain resource and the second time domain resource; the first message is transmitted according to the second transmission configuration.

[0063] It should be noted that, considering that SBFD terminals can transmit uplink on both SBFD symbols and non-SBFD symbols, it is further possible to consider two repeated transmission modes of Msg3: one with only SBFD symbols and the other with SBFD symbols and non-SBFD symbols interleaved.

[0064] In one embodiment, the Msg3 PUSCH (the PUSCH scheduled by the RAR UL grant) can only be transmitted within the first time domain resource, or only within the second time domain resource. This corresponds to the first transmission method of this application.

[0065] It should be noted that, for the first transmission method, the terminal transmits PUSCH on N time slots, and the N time slots can only be either the first time domain resource or the second time domain resource. N is the number of repetitions, and N is a positive integer.

[0066] In another embodiment, the Msg3 PUSCH (the PUSCH scheduled by the RAR UL grant) can be transmitted within the first time domain resources and the second time domain resources. This corresponds to the second transmission method of this application.

[0067] It should be noted that, for the second transmission method, the terminal transmits PUSCH over N time slots. These N time slots can include both the first and second time domain resources. N represents the number of repetitions, and N is a positive integer.

[0068] For example, a network device is configured with a list consisting of four rows, each containing a repetition count and either a first transmission method or a second transmission method. The list is shown below:

[0069] Line 1: Repeated twice, first transmission method;

[0070] Line 2: Repeated twice, second transmission method;

[0071] Line 3: Repeated 4 times, first transmission method;

[0072] Line 4: Repeated 4 times, second transmission method.

[0073] The 2 bits in the MCS field of the RAR UL grant or the DCI format 0_0 scrambled by TC-RNTI are used to indicate one of the four configurations mentioned above.

[0074] Understandably, network devices can configure a first threshold and a second threshold corresponding to the signal strength parameter for the terminal based on the coverage performance of Msg3 when initiating random access on the first time domain resource and the coverage performance of Msg3 when initiating random access on the second time domain resource. This allows the terminal to compare its own signal strength parameter value with the first threshold and the second threshold respectively, and determine whether to initiate a random access request based on the comparison result, as well as whether to initiate a random access request on the first time domain resource or the second time domain resource. This ensures the effectiveness of Msg3 repetition on SBFD for the terminal, thereby improving the demodulation performance of Msg3 PUSCH.

[0075] Based on the above embodiments, this application also proposes a transmission method applied to network devices, such as... Figure 2 As shown, the method may include:

[0076] S201. Configure a first threshold and a second threshold corresponding to the signal strength parameters for the terminal; the first threshold is used to indicate that the terminal does not initiate a random access request or initiates a random access request on the first time domain resource, and the second threshold is used to indicate that the terminal initiates a random access request on the first time domain resource or the second time domain resource; the random access request is used to request repeated transmission of the first message.

[0077] In this embodiment of the application, the first threshold is greater than the second threshold.

[0078] In this embodiment of the application, the type of the first time domain resource is a downlink symbol or a flexible symbol configured with uplink frequency domain resources, and the type of the second time domain resource is an uplink symbol.

[0079] In one embodiment, the network device is further configured with a first transmission configuration, which includes: a first repetition count and / or a second repetition count or a second repetition count list. The first repetition count or the first repetition count list indicates the number of times the terminal transmits the first message on the first time domain resource, and the second repetition count or the second repetition count list indicates the number of times the terminal transmits the first message on the second time domain resource. The first repetition count or the first repetition count list corresponds to the terminal initiating a random access request on the first time domain resource, and the second repetition count or the second repetition count list corresponds to the terminal initiating a random access request on the second time domain resource.

[0080] It should be noted that the first number of repetitions or the list of first number of repetitions is greater than the second number of repetitions or the list of second number of repetitions.

[0081] In another embodiment, the network device is further configured with a second transmission configuration, which includes: a number of repetitions, and / or a repetition mode of a first repetition mode and a second repetition mode, wherein the first repetition mode is used to instruct the terminal to repeat the first message on a first time domain resource or on a second time domain resource, and the second repetition mode is used to instruct the terminal to repeat the first message on the first time domain resource and the second time domain resource.

[0082] It should be noted that S201 is the network device-side step corresponding to S101. For a detailed description of S201, please refer to the description of S101, which will not be repeated here.

[0083] Based on the above embodiments, this application provides a terminal. For example... Figure 3 As shown, the terminal 1 includes:

[0084] The receiving unit 10 is used to receive a first threshold and a second threshold corresponding to the signal strength parameters sent by the network device; the first threshold is used to instruct the terminal not to initiate a random access request or to initiate the random access request on the first time domain resource, and the second threshold is used to instruct the terminal to initiate the random access request on the first time domain resource or the second time domain resource; the random access request is used to request the repeated transmission of the first message.

[0085] Optionally, the first threshold is greater than the second threshold.

[0086] Optionally, the first time-domain resource is a downlink symbol or a flexible symbol configured with uplink frequency domain resources, and the second time-domain resource is an uplink symbol.

[0087] Optionally, the terminal further includes: a transmission unit;

[0088] The receiving unit 10 is further configured to receive a first transmission configuration sent by the network device. The first transmission configuration includes: a first repetition count or a first repetition count list and / or a second repetition count or a second repetition count list. The first repetition count or the first repetition count list indicates the number of times the terminal transmits the first message on the first time domain resource, and the second repetition count or the second repetition count list indicates the number of times the terminal transmits the first message on the second time domain resource. The first repetition count or the first repetition count list corresponds to the terminal initiating the random access request on the first time domain resource, and the second repetition count or the second repetition count list corresponds to the terminal initiating the random access request on the second time domain resource.

[0089] The transmission unit is used to transmit the first message according to the first transmission configuration.

[0090] Optionally, the receiving unit 10 is further configured to receive a second transmission configuration sent by the network device, the second transmission configuration including: a number of repetitions, and / or one of a first transmission method and a second transmission method; the first transmission method is configured to instruct the terminal to transmit the first message on the first time domain resource or on the second time domain resource, and the second transmission method is configured to instruct the terminal to transmit the first message on both the first time domain resource and the second time domain resource;

[0091] The transmission unit is further configured to transmit the first message according to the second transmission configuration.

[0092] This application provides a terminal that receives a first threshold and a second threshold corresponding to signal strength parameters sent by a network device. The first threshold is used to instruct the terminal not to initiate a random access request or to initiate a random access request on a first time domain resource, and the second threshold is used to instruct the terminal to initiate a random access request on either the first or second time domain resource. The random access request is used to request the repeated transmission of a first message. Therefore, the terminal proposed in this embodiment allows the network device to configure a first threshold and a second threshold corresponding to the signal strength parameters for the terminal based on the coverage performance of Msg3 when initiating random access on the first time domain resource and the coverage performance of Msg3 when initiating random access on the second time domain resource. This allows the terminal to compare its own signal strength parameter value with the first and second thresholds respectively, and determine whether to initiate a random access request based on the comparison result, and whether to initiate a random access request on the first or second time domain resource. This ensures the effectiveness of Msg3 repetition on SBFD, thereby improving the demodulation performance of Msg3PUSCH.

[0106] Optionally, the first number of repetitions or the first list of repetitions is greater than the second number of repetitions or the second list of repetitions.

[0107] Optionally, the configuration unit 20 is further configured to configure a second transmission configuration, the second transmission configuration including: a number of repetitions, and / or a repetition mode of a first repetition mode and a second repetition mode, the first repetition mode being used to instruct the terminal to repeat the first message on the first time domain resource or on the second time domain resource, and the second repetition mode being used to instruct the terminal to repeat the first message on both the first time domain resource and the second time domain resource.

[0108] This application provides a network device that configures a first threshold and a second threshold corresponding to signal strength parameters for a terminal. The first threshold is used to instruct the terminal not to initiate a random access request or to initiate a random access request on a first time domain resource. The second threshold is used to instruct the terminal to initiate a random access request on either the first or second time domain resource. The random access request is used to request the repeated transmission of a first message. Therefore, the network device proposed in this embodiment can configure a first threshold and a second threshold corresponding to signal strength parameters for the terminal based on the coverage performance of Msg3 when initiating random access on the first time domain resource and the coverage performance of Msg3 when initiating random access on the second time domain resource. This allows the terminal to compare its own signal strength parameter value with the first and second thresholds respectively, and determine whether to initiate a random access request based on the comparison result, and whether to initiate a random access request on the first or second time domain resource. This ensures the effectiveness of Msg3 repetition on SBFD, thereby improving the demodulation performance of Msg3PUSCH.
