[0083] The communication method, device, equipment, 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 flowchart of a communication method provided by the embodiments of the present application. It should be noted that the communication method of the present embodiment can be applied to a communication device, which can be configured in an electronic device or a chip in some possible embodiments, so that the electronic device or the chip can perform a communication function, for example, the electronic device can be a first terminal device in Figure 1 In addition, in some possible embodiments, the communication device can also be software and the like in an electronic device. For example, communication software and the like. In the following embodiments, the execution subject is taken as an example of the first terminal device.

[0085] As shown in Figure 2 The communication method can include the following steps:

[0086] Step 201, sending first request information to a network device, the first request information is used to request to configure first system information to the first terminal device.

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

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

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

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

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

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

[0093] Step 202, receiving the contention resolution message sent by the network device.

[0094] In some embodiments, the first terminal device can receive the contention resolution message sent by the network device.

[0095] In some embodiments, the contention resolution message can be used by the first terminal device to determine whether the first terminal device fails in the competition with the second terminal device.

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

[0097] Step 203, in the case that the contention resolution message indicates that the first terminal device fails in the competition with the second terminal device, determining at least part of the system information configuration in the first system information according to the second system information configured by the network device for the second terminal device.

[0098] 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 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 according to whether the MAC control element (MAC CE) content in MSG4 is consistent with the common control channel (CCCH) message in MSG3.

[0100] In some embodiments, if the MAC CE content in the MSG4 and the CCCH message in the MSG3 are inconsistent, the contention resolution message indicates that the first terminal device fails in the contention with the second terminal device; if the MAC CE content in the MSG4 and the CCCH message in the MSG3 are consistent, the contention resolution message indicates that the first terminal device succeeds in the contention with the second terminal device.

[0101] In some embodiments, 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 for the second terminal device in the case of contention failure.

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

[0103] The embodiments of the present application can make the first terminal device read part of the system information configuration in advance according to the second system information configured by the network device for the second terminal device in the case of contention failure, and reduce the time delay of the first terminal device in acquiring the first system information in this scenario, by sending the first request information to the network device, the first request information being used to request to configure the first terminal device with the first system information; receiving the contention resolution message sent by the network device; and determining at least part of the system information configuration in the first system information according to the second system information configured by the network device for the second terminal device in the case of the contention resolution message indicating that the first terminal device fails in the contention with the second terminal device.

[0104] Figure 3 Another flowchart of a communication method provided by the embodiments of the present application is shown. The communication method of the present embodiment can be applied to a communication device, which may, in some possible embodiments, 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 may Figure 1 be the first terminal device in the communication system 1000. In addition, in some possible embodiments, the communication device may

[0105] As shown in Figure 3 , the communication method may

[0106] Step 301, sending first request information to a network device.

[0107] Step 302, receiving a contention resolution message sent by the network device.

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

[0109] Step 303, in the case that the contention resolution message indicates that the first terminal device fails in the contention with the second terminal device, comparing the information identifier of the first system information with the information identifier of the second system information, and determining the matching target identifier.

[0110] In some embodiments, the first system information and the second system information correspond to information identifiers respectively.

[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 the first system information and the second system information have an intersection, and if the first system information and the second system information have an intersection, the information identifier corresponding to the intersection is the target identifier.

[0112] In some embodiments, the information identifier contained in both the first system information and the second system information is taken as the 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 for the system information acquisition request; in the case that the message type of the contention resolution message is response information for 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 MAC CE in the contention resolution message is decoded according to the uplink CCCH message in ASN, and if the decoded result is RRCSystemInfoRequest, it is determined that the message type of the contention resolution message is response information for the system information acquisition request; otherwise, it is determined that the message type of the contention resolution message is not response information for the system information acquisition request.

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

[0117] In the embodiments of the present application, the message type of the contention resolution message is judged, so that the first terminal device directly acquires the information identifier of the second system information from the contention resolution message in a case where the message type of the contention resolution message is response information to the system information acquisition request, and the determination efficiency of the target identifier is improved.

[0118] In some embodiments, in a case where the message type of the contention resolution message is not response information to the system information acquisition request, the first terminal device can reinitiate access to reduce the time delay of the first terminal device in acquiring the first system information.

[0119] In step 304, the system information configuration corresponding to the target identifier in the first system information is determined 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 take the system information configuration 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 the embodiments of the present application, the target identifier is determined by comparing the information identifier of the first system information with the information identifier of the second system information, and then the system information configuration corresponding to the target identifier in the first system information is determined based on the target identifier, so that the identification comparison process is simple and the determination efficiency of the system information configuration in the first system information is improved.

[0122] In some embodiments, in a case where there is no matching target identifier, the first request information is sent to the network device again, wherein the channel resource occupied by the first request information sent again is different from that occupied by the first request information sent previously.

[0123] In the embodiments of the present application, the absence of the matching target identifier indicates 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 the embodiment of the present application, the first terminal device sends the first request information to the network device again in the case that there is no matched target identifier, which can make the first terminal device end the current random access process in advance, and initiate access again based on new channel resources, thereby reducing the time delay of the first terminal device in acquiring the first system information.

[0125] In the embodiment of the present application, in the case that the contention resolution message indicates that the first terminal device fails in the 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 the matched target identifier, and the system information configuration corresponding to the target identifier in the first system information is determined according to the system information configuration corresponding to the target identifier in the second system information. 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 Another flowchart of a communication method is provided in the embodiment of the present application. The communication method of the embodiment can be applied to a communication device, which can be configured in an electronic device or a chip in some possible embodiments, so that the electronic device or the chip can perform a communication function. For example, the electronic device can be the first terminal device in the embodiment of the present application. Figure 1 In addition, in some possible embodiments, the communication device can also be software and the like in an electronic device. For example, the software can be communication software and the like. In the following embodiments, the first terminal device is taken as an example for description.

[0127] As shown in Figure 4 , the communication method can include the following steps:

[0128] Step 401, sending first request information to a network device.

[0129] Step 402, receiving a contention resolution message sent by the network device.

[0130] Step 403, in the case that the contention resolution message indicates that the first terminal device fails in the contention with the second terminal device, determining at least part of the system information configuration in the first system information according to the second system information configured by the network device for the second terminal device.

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

[0132] Step 404, in the case that the system information configuration is part of the information in the first system information, sending second request information to the network device, the second request information being used to request to configure the first terminal device with the system information in the first system information except the system information configuration.

[0133] In some embodiments, the first terminal device can send the second request information to the network device in a case where the first system information includes part of the second system information.

[0134] In the embodiments of the present application, in a case where the system information is configured as part of the first system information, the second request information is sent to the network device, which can make the network device broadcast the system information in the first system information that is not acquired by the first terminal device, reduce the power consumption of the network device, and avoid the waste of spectrum resources caused by repeated broadcasting of the same system information.

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

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

[0137] Based on the information identifiers in the first system information except the target identifier, the second request information is sent to the network device, which can make the network device quickly determine the information to be broadcast based on the information identifiers in the second request information, i.e., the system information in the first system information that is not acquired by the first terminal device, and reduce the acquisition delay of the system information.

[0138] In the embodiments of the present application, in a case where the system information is configured as part of the first system information, the second request information is sent to the network device, which is used to request the network device to configure the first terminal device with the system information in the first system information except the system information configuration; this can make the network device broadcast the system information in the first system information that is not acquired by the first terminal device, reduce the power consumption of the network device, and avoid the waste of spectrum resources caused by repeated broadcasting of the same system information.
