[0083] The communication method, apparatus, device, chip and readable storage medium of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0084] Figure 2 A flow chart of a communication method provided in an embodiment of the present application. It should be noted that the communication method of this embodiment can be applied to a communication device. In some possible embodiments, the device can be configured in an electronic device or a chip so that the electronic device or the chip can perform a communication function. For example, the electronic device can be Figure 1 In addition, in some possible embodiments, the communication device may also be software in an electronic device, etc. The software may be, for example, communication software, etc. In the following embodiments, the execution subject is taken as the first terminal device as an example for description.

[0085] like Figure 2 As shown, the communication method may include the following steps:

[0086] Step 201: Send first request information to a network device, where the first request information is used to request configuration of first system information for a first terminal device.

[0087] In some embodiments, the first terminal device can send first request information to the network device.

[0088] In some embodiments, the first request information is used by the network device to configure the first system information for the first terminal device.

[0089] In some embodiments, the first system information may refer to on-demand system information.

[0090] In some embodiments, the first request information may include an SI list, and the SI list includes identification information of the first system information.

[0091] In some embodiments, the first request information may refer to message MSG3, and the SI list is included in a radio resource control system information request (RRCSystemInfoRequest) message in MSG3.

[0092] In some embodiments, the first terminal device may select a physical random access channel (PRACH) resource, such as a random access preamble, a PRACH transmission timing, etc., and send a first request information to the network device based on the selected PRACH resource.

[0093] Step 202: Receive a contention resolution message sent by a network device.

[0094] In some embodiments, the first terminal device is capable of receiving a contention resolution message sent by the network device.

[0095] In some embodiments, the contention resolution message is used by the first terminal device to determine whether the first terminal device has failed in contention with the second terminal device.

[0096] In some embodiments, the contention resolution message may refer to MSG4.

[0097] Step 203: When the contention resolution message indicates that the first terminal device has failed in contention with the second terminal device, determine at least part of the system information configuration in the first system information according to the second system information configured by the network device to the second terminal device.

[0098] In some embodiments, the first terminal device can determine whether the first terminal device has failed in contention with the second terminal device based on the contention resolution message.

[0099] In some embodiments, the first terminal device can determine whether the first terminal device fails in the competition with the second terminal device based on whether the content of the MAC control element (MAC ControlElement, MAC CE) in MSG4 is consistent with the common control channel (Common Control Channel, CCCH) message in MSG3.

[0100] In some embodiments, if the MACCE content in MSG4 and the CCCH message in MSG3 are inconsistent, the contention resolution message indicates that the first terminal device has failed in the contention with the second terminal device; if the MACCE content in MSG4 and the CCCH message in MSG3 are consistent, the contention resolution message indicates that the first terminal device has succeeded in the contention with the second terminal device.

[0101] In some embodiments, when the first terminal device fails in contention, the first terminal device can determine at least part of the system information configuration in the first system information according to the second system information configured by the network device to the second terminal device.

[0102] In some embodiments, if the second system information includes all the information in the first system information, at least part of the system information configuration may refer to the first system information; if the second system information includes part of the information in the first system information, at least part of the system information configuration may refer to part of the information in the first system information. For example, if the first system information includes B, C, and D, and the second system information includes A, B, and C, at least part of the system information configuration refers to B and C; if the first system information includes A and B, and the second system information includes A, B, and C, at least part of the system information configuration refers to A and B.

[0103] The embodiment of the present application sends a first request message to a network device, where the first request message is used to request configuration of the first system information to the first terminal device; receives a contention resolution message sent by the network device; and determines at least part of the system information configuration in the first system information according to the second system information configured by the network device to the second terminal device when the contention resolution message indicates that the first terminal device has failed in contention with the second terminal device; and enables the first terminal device to read part of the system information configuration in advance according to the second system information configured by the network device to the second terminal device when the contention resolution message indicates that the first terminal device has failed in contention with the second terminal device, thereby reducing the delay in the first terminal device acquiring the first system information in this scenario.

[0104] Figure 3 A flow chart of another communication method provided in an embodiment of the present application. The communication method of this embodiment can be applied to a communication device. In some possible embodiments, the device can be configured in an electronic device or a chip so that the electronic device or the chip can perform a communication function. For example, the electronic device can be Figure 1 In addition, in some possible embodiments, the communication device may also be software in an electronic device, etc. The software may be, for example, communication software, etc. In the following embodiments, the execution subject is taken as the first terminal device as an example for description.

[0105] like Figure 3 As shown, the communication method may include the following steps:

[0106] Step 301: Send first request information to a network device.

[0107] Step 302: Receive a contention resolution message sent by a network device.

[0108] It should be noted that the specific implementation of steps 301 and 302 can refer to the various embodiments of the present application and will not be described in detail here.

[0109] Step 303: When the contention resolution message indicates that the first terminal device has failed in contention with the second terminal device, the information identifier of the first system information is compared with the information identifier of the second system information to determine a matching target identifier.

[0110] In some embodiments, the first system information and the second system information are respectively associated with information identifiers.

[0111] In some embodiments, the information identifier of the first system information is compared with the information identifier of the second system information to determine whether the first system information is a subset of the second system information; if the first system information is a subset of the second system information, the information identifier of the first system information is the target identifier; if the first system information is not a subset of the second system information, it is determined whether there is an intersection between the first system information and the second system information; if there is an intersection between the first system information and the second system information, the information identifier corresponding to the intersection is the target identifier.

[0112] In some embodiments, an information identifier included in both the first system information and the second system information is used as a target identifier.

[0113] In some embodiments, the request information sent by the first terminal device to the network device and the request information sent by the second terminal device to the network device both belong to system information acquisition requests.

[0114] In some embodiments, the contention resolution message is decoded to determine whether the message type of the contention resolution message is response information to the system information acquisition request; when the message type of the contention resolution message is response information to the system information acquisition request, the information identifier of the second system information is read from the contention resolution message.

[0115] As an example, the MACCE in the contention resolution message is ASN decoded according to the uplink CCCH message. If the decoded message is RRCSystemInfoRequest, the message type of the contention resolution message is determined to be the response information for the system information acquisition request; otherwise, it is determined that the message type of the contention resolution message is not the response information for the system information acquisition request.

[0116] In some embodiments, when the message type of the contention resolution message is response information to a system information acquisition request, an SI list is acquired from the decoded RRCSystemInfoRequest message, where the SI list includes an information identifier of the second system information.

[0117] In an embodiment of the present application, the message type of the contention resolution message is judged, so that the first terminal device can directly obtain the information identifier of the second system information from the contention resolution message when the message type of the contention resolution message is response information to the system information acquisition request, thereby improving the efficiency of determining the target identifier.

[0118] In some embodiments, when the message type of the contention resolution message is not response information to the system information acquisition request, the first terminal device may re-initiate access to reduce the delay for the first terminal device to acquire the first system information.

[0119] Step 304: Determine the system information configuration corresponding to the target identifier in the first system information according to the system information configuration corresponding to the target identifier in the second system information.

[0120] In some embodiments, the first terminal device can configure the system information corresponding to the target identifier in the second system information as the system information configuration corresponding to the target identifier in the first system information. That is, the first terminal device can read the system information configuration corresponding to the target identifier from the second system information configured by the network device to the second terminal device based on the target identifier.

[0121] In an embodiment of the present application, the information identifier of the first system information is compared with the information identifier of the second system information to determine the target identifier, and then the system information configuration corresponding to the target identifier in the first system information is determined based on the target identifier. The identifier comparison process is simple, which improves the efficiency of determining the system information configuration in the first system information.

[0122] In some embodiments, when there is no matching target identifier, the first request information is sent again to the network device, wherein the channel resources occupied by the first request information sent again are different from those of the first request information sent previously.

[0123] In the embodiment of the present application, there is no matching target identifier, indicating that the second system information configured by the network device to the second terminal device does not include the system information requested by the first terminal device.

[0124] In an embodiment of the present application, when there is no matching target identifier, sending the first request information to the network device again can enable the first terminal device to end the random access process ahead of schedule and initiate access again based on new channel resources, thereby reducing the delay for the first terminal device to obtain the first system information.

[0125] In an embodiment of the present application, when a contention resolution message indicates that the first terminal device has failed in contention with the second terminal device, the information identifier of the first system information is compared with the information identifier of the second system information to determine a matching target identifier; based on the system information configuration corresponding to the target identifier in the second system information, the system information configuration corresponding to the target identifier in the first system information is determined; since the information identifier comparison process is simple, the first terminal device can quickly determine the target identifier, thereby improving the efficiency of the first terminal device in determining the system information configuration in the first system information.

[0126] Figure 4 A flow chart of another communication method provided in an embodiment of the present application. The communication method of this embodiment can be applied to a communication device. In some possible embodiments, the device can be configured in an electronic device or a chip so that the electronic device or the chip can perform a communication function. For example, the electronic device can be Figure 1 In addition, in some possible embodiments, the communication device may also be software in an electronic device, etc. The software may be, for example, communication software, etc. In the following embodiments, the execution subject is taken as the first terminal device as an example for description.

[0127] like Figure 4 As shown, the communication method may include the following steps:

[0128] Step 401: Send first request information to a network device.

[0129] Step 402: Receive a contention resolution message sent by a network device.

[0130] Step 403: When the contention resolution message indicates that the first terminal device has failed in contention with the second terminal device, determine at least part of the system information configuration in the first system information according to the second system information configured by the network device to the second terminal device.

[0131] It should be noted that the specific implementation of steps 401-403 can refer to the various embodiments of the present application and will not be described in detail here.

[0132] Step 404: When the system information configuration is part of the first system information, second request information is sent to the network device, where the second request information is used to request configuration of system information other than the system information configuration in the first system information to the first terminal device.

[0133] In some embodiments, the first terminal device may send the second request information to the network device when the second system information includes part of the information in the first system information.

[0134] In an embodiment of the present application, when the system information is configured as part of the information in the first system information, sending a second request information to the network device can enable the network device to broadcast system information in the first system information that the first terminal device has not obtained, thereby reducing the power consumption of the network device and avoiding the waste of spectrum resources caused by repeated broadcasting of the same system information.

[0135] In some embodiments, the first terminal device may compare the information identifier of the first system information with the information identifier of the second system information to determine a matching target identifier; and send a second request information to the network device based on the information identifier other than the target identifier in the first system information.

[0136] As an example, the second request information includes the information identifier in the first system information except the target identifier.

[0137] Sending a second request message to the network device based on the information identifier other than the target identifier in the first system information can enable the network device to quickly determine the information to be broadcast, that is, the system information in the first system information that the first terminal device has not obtained, based on the information identifier in the second request message, thereby reducing the delay in obtaining the system information.

[0138] In an embodiment of the present application, when the system information is configured as part of the information in the first system information, second request information is sent to the network device, and the second request information is used to request that system information other than the system information configuration in the first system information be configured to the first terminal device; this enables the network device to broadcast system information in the first system information that is not obtained by the first terminal device, thereby reducing the power consumption of the network device and avoiding the waste of spectrum resources caused by repeated broadcasting of the same system information.

[0142] In some embodiments, the network device is capable of receiving request information sent by the first terminal device and the second terminal device.

[0143] In some embodiments, the first terminal device and the second terminal device refer to two different terminal devices, and the first system information and the second system information may refer to the same system information or different system information.

[0144] Step 502: Broadcast contention resolution information based on the request information.

[0145] The contention resolution information is used by the first terminal device to determine whether the first terminal device fails in contention with the second terminal device, and in case of failure, to determine at least part of the system information configuration in the first system information according to the second system information.

[0146] In some embodiments, the network device can determine a terminal device that successfully competes from the first terminal device and the second terminal device based on the request information, and broadcast contention resolution information based on the terminal device that successfully competes.

[0158] In some embodiments, the network device is used to broadcast system information corresponding to the target request information while broadcasting the contention resolution information.

[0159] Based on the maximum value of the number of information identifiers, the network device can respond to the terminal device with the largest set of system information, thereby reducing the amount of repeated broadcasts of system information and reducing the power consumption of the network device.

[0160] In an embodiment of the present application, based on request information, the number of information identifiers of the first system information and the number of information identifiers of the second system information are obtained; according to the number of information identifiers, target request information for which competition has been successful is determined, and based on the target request information, competition resolution information is broadcast; and when competition occurs between the first terminal device and the second terminal device, the request information to be responded to can be determined based on the number of information identifiers, thereby reducing the amount of repeated broadcasts of system information and reducing the power consumption of network devices.
