Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to a random access method and apparatus. Background Technology

[0002] In wireless communication systems, the process of establishing a connection between a terminal device and a network device is commonly referred to as random access (RA). The terminal device can send a random access message to the network device to initiate random access. For coverage enhancement, the transmission of the random access message can be improved. For example, repeated transmission of the random access message can enhance coverage. The terminal device can use the same transmission beam to repeatedly transmit the random access message, or it can use different transmission beams. When the terminal device supports both using the same and different transmission beams to repeatedly transmit the random access message, it cannot determine how to transmit the random access message. Summary of the Invention

[0003] This application provides a random access method and apparatus, which enables the terminal device to determine how to transmit random access messages when the terminal device supports both using the same transmission beam to repeatedly transmit random access messages and using different transmission beams to repeatedly transmit random access messages.

[0004] Firstly, this application provides a random access method applied in a terminal device, the method comprising:

[0005] During the initial random access process, random access messages may be repeatedly transmitted using the same transmission beam, or repeatedly transmitted using different transmission beams, or a single random access message may be sent. The terminal device supports both repeatedly transmitting random access messages using the same transmission beam and repeatedly transmitting random access messages using different transmission beams.

[0006] Based on the method described in the first aspect, when the terminal device supports both using the same transmission beam to repeatedly transmit random access messages and using different transmission beams to repeatedly transmit random access messages, it is possible to determine how to transmit the random access messages.

[0007] In one possible implementation, a system message sent by a network device may also be received, indicating that: the random access message is repeatedly transmitted using the same transmission beam during the initial random access process, or the random access message is repeatedly transmitted using different transmission beams during the initial random access process, or the random access message is sent once during the initial random access process.

[0008] Based on this possible implementation, random access messages can be sent more flexibly during the initial random access process.

[0009] In one possible implementation, when a first random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process; when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using different transmission beams during the initial random access process; wherein, the first random access resource is the random access resource used for repeatedly transmitting the random access message using the same transmission beam, and the second random access resource is the random access resource used for repeatedly transmitting the random access message using different transmission beams.

[0010] Based on this possible implementation, the method of sending random access messages can be implicitly indicated, which helps to reduce the indication overhead.

[0011] In one possible implementation, when neither the first nor the second random access resource is configured in the system message, the system message indicates that a random access message should be sent during the initial random access process. Based on this possible implementation, the method of sending the random access message can be implicitly indicated, which helps to reduce indication overhead.

[0012] In one possible implementation, when the system message is configured with a first random access resource, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process; when the system message is not configured with a first random access resource, the system message indicates that a random access message is sent once during the initial random access process; wherein, the first random access resource is the random access resource used to repeatedly transmit the random access message using the same transmission beam.

[0013] Based on this possible implementation, the method of sending random access messages can be implicitly indicated, which helps to reduce indication overhead.

[0014] In one possible implementation, when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using different transmission beams during the initial random access process; when no second random access resource is configured in the system message, the system message indicates that a random access message is sent once during the initial random access process; the second random access resource is the random access resource used to repeatedly transmit the random access message using different transmission beams.

[0015] Based on this possible implementation, the method of sending random access messages can be implicitly indicated, which helps to reduce the indication overhead.

[0016] In one possible implementation, the system message is either a System Information Block (SIB) or a Master Information Block (MIB).

[0017] Secondly, this application provides a random access method applied in a network device, the method comprising:

[0018] A system message is sent to the terminal device, indicating that: the random access message is repeatedly transmitted using the same transmission beam during the initial random access process, or the random access message is repeatedly transmitted using different transmission beams during the initial random access process, or the random access message is sent once during the initial random access process; wherein, the terminal device supports repeatedly transmitting the random access message using the same transmission beam, and also supports repeatedly transmitting the random access message using different transmission beams.

[0019] In one possible implementation, when a first random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process; when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using different transmission beams during the initial random access process; wherein, the first random access resource is the random access resource used for repeatedly transmitting the random access message using the same transmission beam, and the second random access resource is the random access resource used for repeatedly transmitting the random access message using different transmission beams.

[0020] In one possible implementation, if the system message does not specify a first random access resource and a second random access resource, the system message indicates that a random access message should be sent during the initial random access process.

[0021] In one possible implementation, when the system message is configured with a first random access resource, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process; when the system message is not configured with a first random access resource, the system message indicates that a random access message is sent once during the initial random access process; wherein, the first random access resource is the random access resource used to repeatedly transmit the random access message using the same transmission beam.

[0022] In one possible implementation, when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using different transmission beams during the initial random access process; when no second random access resource is configured in the system message, the system message indicates that a random access message is sent once during the initial random access process; the second random access resource is the random access resource used to repeatedly transmit the random access message using different transmission beams.

[0023] In one possible implementation, the system message is either a System Information Block (SIB) or a Master Information Block (MIB).

[0024] The beneficial effects in the second aspect can be found in the beneficial effects in the first aspect, and will not be repeated here.

[0025] Thirdly, this application provides a random access method applied in a terminal device, the method comprising:

[0026] Receive Radio Resource Control (RRC) signaling sent by the network device. The RRC signaling indicates that the random access message should be repeatedly transmitted using the same transmission beam during a non-initial random access process, or indicates that the random access message should be repeatedly transmitted using different transmission beams during a non-initial random access process.

[0027] During non-initial random access procedures, random access messages are sent based on RRC signaling.

[0028] Among them, the terminal equipment supports repeating random access messages using the same transmission beam, and also supports repeating random access messages using different transmission beams.

[0029] Based on the method described in the third aspect, the terminal device can send random access messages more flexibly during non-initial random access processes.

[0030] Fourthly, this application provides a random access method applied in a network device, the method comprising:

[0031] Send Radio Resource Control (RRC) signaling to the terminal device. The RRC signaling indicates that the random access message is repeatedly transmitted using the same transmission beam during a non-initial random access process, or indicates that the random access message is repeatedly transmitted using a different transmission beam during a non-initial random access process.

[0032] Among them, the terminal equipment supports repeating random access messages using the same transmission beam, and also supports repeating random access messages using different transmission beams.

[0033] Based on the method described in the fourth aspect, terminal devices can send random access messages more flexibly during non-initial random access processes.

[0034] Fifthly, this application provides a random access method applied in a terminal device, the method comprising:

[0035] Multiple reference signals are measured to obtain the measurement results for multiple reference signals;

[0036] During random access, random access messages are repeatedly transmitted using the same or different transmission beams based on the maximum value among multiple reference signal measurement results; wherein, the terminal device supports repeatedly transmitting random access messages using the same transmission beam as well as repeatedly transmitting random access messages using different transmission beams.

[0037] Based on the method described in the fifth aspect, the terminal device can flexibly determine the sending method of the random access message on its own, without requiring the network device to instruct the sending method of the random access message, which is beneficial to saving transmission resources.

[0038] In one possible implementation, random access messages are repeatedly transmitted using the same or different transmission beams based on the maximum value among multiple reference signal measurements, including:

[0039] If the maximum value among the measurement results of multiple reference signals is greater than or not less than the first threshold, the random access message is repeatedly transmitted using the same transmission beam.

[0040] If the maximum value among the multiple reference signal measurement results is less than or not greater than the first threshold, then random access messages are repeatedly transmitted using different transmission beams.

[0041] In one possible implementation, random access messages are repeatedly transmitted using the same or different transmission beams based on the maximum value among multiple reference signal measurements, including:

[0042] If the maximum value among the multiple reference signal measurement results is greater than or not less than the first threshold, then random access messages are repeatedly transmitted using different transmission beams;

[0043] If the maximum value among multiple reference signal measurement results is less than or not greater than the first threshold, the random access message is repeatedly transmitted using the same transmission beam.

For example, a terminal device is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (such as on airplanes, balloons, and satellites).

This device can be installed in the network equipment. The embodiments of this application do not limit the specific technology or specific equipment form used in the network equipment.

[0069] To enable a terminal device to determine how to transmit random access messages when it supports both repeating random access messages using the same transmission beam and repeating random access messages using different transmission beams, this application provides a random access method, apparatus, chip, and module device. The random access method, apparatus, chip, and module device provided in the embodiments of this application are further described in detail below.

[0070] Figure 2 This is a flowchart illustrating a random access method provided in an embodiment of this application. Figure 2As shown, the random access method includes the following step 201. Figure 2 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 2 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 2 The method will be explained using terminal devices and network devices as examples.

[0071] 201. During the initial random access process, the terminal device may repeatedly transmit random access messages using the same transmit beam, or the terminal device may repeatedly transmit random access messages using different transmit beams, or the terminal device may send a random access message only once. Correspondingly, the network device can receive the random access messages transmitted by the terminal device. The random access information may refer to the physical random access channel (PRACH), Message-1 (Msg.1), or a preamble sequence.

[0072] Among them, the terminal equipment supports repeating random access messages using the same transmission beam, and also supports repeating random access messages using different transmission beams.

[0073] For ease of description later, the use of the same transmission beam to repeatedly transmit random access messages by the terminal device is called transmission mode 1, the use of different transmission beams to repeatedly transmit random access messages by the terminal device is called transmission mode 2, and the use of the terminal device to send a random access message once is called transmission mode 3.

[0074] In one possible implementation, during the initial random access process, the terminal device may default to sending mode 1. Alternatively, the terminal device may default to sending mode 2. Or, the terminal device may default to sending mode 3. Since the network device is unaware of the terminal device's capabilities during the initial access process—that is, it does not know which random access message sending modes the terminal device supports—it is impossible for the network device to instruct the terminal device which mode to use for initial random access. Therefore, the terminal device may default to sending mode 1, mode 2, or mode 3 during the initial random access process.

[0075] In one possible implementation, the network device may also send a system message to the terminal device, indicating that: the random access message may be repeatedly transmitted using the same transmission beam during the initial random access process; or, the random access message may be repeatedly transmitted using different transmission beams during the initial random access process; or, the random access message may be transmitted only once during the initial random access process. Correspondingly, the terminal device may also receive the system message sent by the network device. During the initial random access process, the terminal device transmits the random access message according to the transmission method indicated by the system message. Based on this possible implementation, the terminal device can transmit the random access message more flexibly during the initial random access process.

[0076] In this possible implementation, the network device defaults to supporting at least two of the following methods: sending method 1, sending method 2, and sending method 3.

[0077] Assuming that the network device defaults to supporting both sending mode 1 and sending mode 2 for the terminal device, the network device can instruct the terminal device to use either sending mode 1 or sending mode 2 through system messages.

[0078] Assuming that the network device defaults to supporting both sending mode 1 and sending mode 3 for the terminal device, the network device can instruct the terminal device to use either sending mode 1 or sending mode 3 via system messages.

[0079] Assuming that the network device defaults to supporting both sending mode 2 and sending mode 3 for the terminal device, the network device can instruct the terminal device to use either sending mode 2 or sending mode 3 through system messages.

[0080] Assuming that the network device defaults to supporting sending methods 1, 2, and 3 for the terminal device, the network device can instruct the terminal device through system messages whether to use sending method 1, 2, or 3.

[0081] I. The following section describes the specific implementation method for instructing terminal devices to use either sending method 1 or sending method 2 for system messages:

[0082] Method 1: The system message explicitly indicates whether the terminal device should use sending method 1 or sending method 2.

[0083] For example, when the system message includes an identifier for sending method 1, it instructs the terminal device to use sending method 1; when the system message includes an identifier for sending method 2, it instructs the terminal device to use sending method 2.

[0084] Method 2: Implicitly indicate in the system message whether the terminal device should use sending method 1 or sending method 2.

[0085] For example, when a first random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process (i.e., transmission mode 1 is used); when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using a different transmission beam during the initial random access process (i.e., transmission mode 2 is used); wherein, the first random access resource is the random access resource used for repeatedly transmitting random access messages using the same transmission beam, and the second random access resource is the random access resource used for repeatedly transmitting random access messages using a different transmission beam.

[0086] The implicit method of instructing terminal devices to send random access messages helps reduce instruction overhead.

[0087] II. The following section describes the specific implementation methods for instructing terminal devices to use either sending method 1 or sending method 3 for system messages:

[0088] Method 1: The system message explicitly indicates whether the terminal device should use sending method 1 or sending method 3.

[0089] For example, when the system message includes an identifier for sending mode 1, it instructs the terminal device to use sending mode 1; when the system message includes an identifier for sending mode 3, it instructs the terminal device to use sending mode 3.

[0090] Method 2: Implicitly indicate in the system message whether the terminal device should use sending method 1 or sending method 3.

[0091] For example, when the system message is configured with a first random access resource, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process (i.e., transmission mode 1 is used); when the system message is not configured with a first random access resource, the system message indicates that a random access message is sent once during the initial random access process (i.e., transmission mode 2 is used); wherein, the first random access resource is the random access resource used to repeatedly transmit the random access message using the same transmission beam.

[0092] The implicit method of instructing terminal devices to send random access messages helps reduce instruction overhead.

[0093] III. The following section describes the specific implementation of whether the system message instructs the terminal device to use sending method 2 or sending method 3:

[0094] Method 1: The system message explicitly indicates whether the terminal device should use sending method 2 or sending method 3.

[0095] For example, when the system message includes an identifier for sending method 2, it instructs the terminal device to use sending method 2; when the system message includes an identifier for sending method 3, it instructs the terminal device to use sending method 3.

[0096] Method 2: Implicitly indicate in the system message whether the terminal device should use sending method 2 or sending method 3.

[0097] For example, when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using different transmission beams during the initial random access process (i.e., transmission mode 2 is used); when a second random access resource is not configured in the system message, the system message indicates that a random access message is sent once during the initial random access process (i.e., transmission mode 3 is used); the second random access resource is the random access resource used to repeatedly transmit random access messages using different transmission beams.

[0098] The implicit method of instructing terminal devices to send random access messages helps reduce instruction overhead.

[0099] IV. The following section describes the specific implementation methods for instructing terminal devices to use either sending method 1, sending method 2, or sending method 3 for system messages:

[0100] Method 1: The system message explicitly indicates whether the terminal device should use sending method 1, sending method 2, or sending method 3.

[0101] For example, when the system message includes an identifier for sending method 1, it instructs the terminal device to use sending method 1; when the system message includes an identifier for sending method 2, it instructs the terminal device to use sending method 2; when the system message includes an identifier for sending method 3, it instructs the terminal device to use sending method 3.

[0102] Method 2: Implicitly indicate in the system message whether the terminal device should use sending method 1, sending method 2, or sending method 3.

[0103] For example, when a first random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using the same transmission beam during the initial random access process (i.e., transmission mode 1); when a second random access resource is configured in the system message, the system message indicates that the random access message is repeatedly transmitted using a different transmission beam during the initial random access process (i.e., transmission mode 2); when neither a first nor a second random access resource is configured in the system message, the system message indicates that a random access message is sent once during the initial random access process (i.e., transmission mode 3). Here, the first random access resource is the random access resource used for repeatedly transmitting random access messages using the same transmission beam, and the second random access resource is the random access resource used for repeatedly transmitting random access messages using a different transmission beam.

[0104] The implicit method of instructing terminal devices to send random access messages helps reduce instruction overhead.

[0105] In one possible implementation, the system message can be a system information block (SIB) or a master information block (MIB).

[0106] It can be seen that, based on Figure 2 The described method enables the terminal device to determine how to transmit random access messages when the terminal device supports both using the same transmit beam to repeatedly transmit random access messages and using different transmit beams to repeatedly transmit random access messages.

[0107] Figure 3 This is a flowchart illustrating a random access method provided in an embodiment of this application. Figure 3 As shown, the random access method includes the following steps 301 and 302. Figure 3 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 3 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 3 The method will be explained using terminal devices and network devices as examples.

[0108] 301. The network device sends an RRC signaling message to the terminal device, which instructs the terminal device to repeatedly transmit random access messages using the same transmission beam during non-initial random access procedures, or instructs the terminal device to repeatedly transmit random access messages using different transmission beams during non-initial random access procedures. Accordingly, the terminal device can receive the RRC signaling message.

[0109] Among them, the terminal equipment supports repeating random access messages using the same transmission beam, and also supports repeating random access messages using different transmission beams.

[0110] 302. During a non-initial random access process, the terminal device sends a random access message based on RRC signaling. Correspondingly, the network device can receive this random access message.

[0111] For example, if the RRC signaling instructs the terminal device to repeatedly transmit random access messages using the same transmission beam during a non-initial random access process, then the terminal device will repeatedly transmit random access messages using the same transmission beam during the non-initial random access process. If the RRC signaling instructs the terminal device to repeatedly transmit random access messages using different transmission beams during a non-initial random access process, then the terminal device will repeatedly transmit random access messages using different transmission beams during the non-initial random access process.

[0112] In this embodiment, after initial random access, the terminal device can report its capability information to the network device via higher-layer signaling. This allows the network device to determine whether the terminal device supports repeated transmission of random access messages using the same transmission beam or different transmission beams. The network device can then instruct the terminal device on which transmission method to use for sending random access messages during non-initial random access processes. Alternatively, the terminal device may not need to report capability information. The network device can assume that the terminal device supports both repeated transmission of random access messages using the same and different transmission beams.

[0113] based on Figure 3 The described method enables terminal devices to send random access messages more flexibly during non-initial random access processes.

[0114] Figure 4 This is a flowchart illustrating a random access method provided in an embodiment of this application. Figure 4 As shown, the random access method includes the following step 401. Figure 4 The method shown can be implemented by terminal devices and network devices. Alternatively, Figure 4 The method shown can be executed by a chip in a terminal device or a chip in a network device. Figure 4 The method will be explained using terminal devices and network devices as examples.

[0115] 401. The terminal equipment measures multiple reference signals and obtains multiple reference signal measurement results.

[0116] The measurement result can be the reference signal receiving power (RSRP) or other reference signal measurement results, which are not limited in the embodiments of this application.

[0117] Optionally, the reference signal can be a synchronous signal block (SSB) or a channel state information reference signal (CSI-RS).

[0118] 402. During the random access process, the terminal device repeatedly transmits the random access message using the same or different transmission beams based on the maximum value among the multiple reference signal measurement results.

[0119] Among them, the terminal equipment supports repeating random access messages using the same transmission beam, and also supports repeating random access messages using different transmission beams.

[0120] Optionally, during the initial random access process or non-initial random access process, the terminal device may repeatedly transmit random access messages using the same or different transmission beams based on the maximum value among the multiple reference signal measurement results.

[0121] In one possible implementation, the terminal device repeatedly transmits random access messages using the same or different transmission beams based on the maximum value among multiple reference signal measurement results.

[0122] If the maximum value among multiple reference signal measurement results is greater than or not less than the first threshold, the terminal device uses the same transmission beam to repeatedly transmit random access messages;

[0123] If the maximum value among multiple reference signal measurement results is less than or not greater than the first threshold, the terminal device repeatedly transmits random access messages using different transmission beams.

[0124] In one possible implementation, the terminal device repeatedly transmits random access messages using the same or different transmission beams based on the maximum value among multiple reference signal measurement results.

[0125] If the maximum value among the multiple reference signal measurement results is greater than or not less than the first threshold, the terminal device repeatedly transmits random access messages using different transmission beams.

[0126] If the maximum value among multiple reference signal measurement results is less than or not greater than the first threshold, the terminal device repeatedly transmits random access messages using the same transmission beam.

[0127] Optionally, the first threshold can be predefined by the protocol or configured by the network device.

[0128] Optionally, if the physical random access occasion (RO) resource or the preamble resource is independent, the network device can distinguish which transmission method the terminal device used to send the random access message by the resource location or resource index number received from the random access message.

[0129] based on Figure 4 The described method allows the terminal device to flexibly determine the sending method of random access messages without requiring the network device to instruct it, which helps save transmission resources.
