Description

Technical Field

[0001] The present specification relates to the field of communication technology, and in particular to an uplink resynchronization method and device. Background Art

[0002] During mobile network communication, the terminal device usually needs to reconnect to the network after being disconnected from the network because the terminal device has not communicated with the network for a long time, or due to reasons such as shutdown, network switching, and network failure. In this case, it is necessary to perform uplink resynchronization on the configuration information of the terminal device in the base station device, that is, restore the terminal device that has reconnected to the network to the previous configuration, so that the base station device can re-allocate communication resources to the terminal device based on the uplink resynchronization configuration information, so that the terminal device can reconnect to the network and communicate based on the uplink resynchronization configuration information.

[0003] However, currently after completing uplink resynchronization of the configuration information of the terminal device, the triggering cause of the uplink resynchronization is usually not determined. In this case, it is difficult for the base station device to determine how to process the communication service after the uplink resynchronization, and communication needs cannot be effectively met.

[0024] This specification provides an uplink resynchronization device, including:

[0025] A receiving module, used for receiving a MAC PDU sent by a terminal device;

[0026] A parsing module, used for parsing the fields in the MAC PDU in order;

[0034] It can be seen from the above method that when the configuration information of the terminal device is uplink resynchronized, the MAC PDU sent to the base station device carries not only the MAC CE field and the MAC SDU field, but also the triggering cause information of the uplink resynchronization. In this way, after receiving the MAC PDU, the base station device can not only perform uplink resynchronization on the terminal device based on the analysis result of the MAC CE field, but also execute the current communication service according to the triggering cause information carried by the MAC PDU, thereby fully meeting the communication needs of the current communication service.

[0043] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0044] The Media Access Control (MAC) Protocol Data Unit (PDU) is a unit for transmitting data between peer levels and plays an important role in the process of data communication. For ease of understanding, this specification provides a schematic diagram of the structure of a conventional MAC PDU, such as Figure 1 shown.

[0045] Figure 1 A schematic diagram of the format of a conventional MAC PDU provided in this specification.

[0046] Among them, the MAC PDU contains several MAC sub PDUs, and the contents contained in each MAC sub PDU are different, including: a MAC subheader; a MAC subheader and a MAC service data unit (ServiceData Unit, SDU); a MAC subheader and a MAC control element (Control Element, CE); or, a MAC subheader and padding PADDING, where the subheader is the subheader corresponding to each MAC sub PDU.

[0047] During actual communication, the MAC subPDU may be processed independently, and the UL MAC subPDU(s) including the MAC CE(s) is located after the UL MAC subPDU(s) including the MAC SDU.

[0048] When uplink resynchronization is triggered, the terminal device can send a MAC PDU in the above format to the base station device through the Msg3 Physical Uplink Shared Channel (PUSCH). After receiving the MAC PDU, the base station device cannot further process the service based on the triggering cause because the MAC PDU cannot carry the triggering cause of uplink resynchronization.

[0049] Moreover, since the MAC CE is located after the MAC SDU, when the base station device processes the MAC PDU, it will first parse the MAC SDU. At this time, since the MAC CE has not been parsed, the uplink resynchronization of the terminal device configuration information cannot be completed. In this case, although the MAC SDU data is located at the front end of the MAC PDU, since the uplink resynchronization has not been completed, it still needs to suspend and wait for the parsing result of the next MAC subPDU (ie, MAC CE).

[0050] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0051] Figure 2 A schematic diagram of a flow chart of an uplink resynchronization method provided in this specification includes the following steps:

[0052] S201: When it is determined that the transport block size TBS meets a preset condition, a triggering cause for the uplink resynchronization to be currently executed is obtained.

[0053] Typically, there are a variety of reasons for uplink resynchronization of configuration information of a terminal device (such as a user equipment (UE)) in a base station device (such as a GNB), such as the terminal not communicating with the network for a long time, the terminal being disconnected from the network due to some reason (such as terminal shutdown, network failure, etc.), the terminal switching networks (such as the terminal device moving from one base station coverage area to another, or switching from one network type to another), the terminal configuration information being lost or damaged, the network being updated or the software being upgraded, etc. In this case, the base station device needs to identify the identification information of the terminal through the signaling sent by the terminal, and restore the configuration information of the terminal based on the identification information, thereby achieving uplink resynchronization of the configuration information so that the terminal can re-establish communication with the base station.

[0054] In the above case, when the terminal device executes communication services such as user paging, terminal uplink calling signaling, terminal uplink main voice service, terminal key service, etc., uplink resynchronization will be triggered.

[0055] When the UE side has a need to upload a triggering factor, the terminal device can first determine whether the transport block size (TBS) meets the preset conditions. When it is determined that the preset conditions are met, the terminal device can obtain the triggering factor for uplink resynchronization. The triggering factor is used to indicate when the uplink resynchronization is triggered by the terminal device when executing a certain communication service.

[0056] In this specification, the above preset condition may refer to that the total field size of the UE access control MAC CE field, the MAC CE field and the MAC SDU field is not greater than TBS, and TBS is sufficient to carry the MAC CE field, the MAC SDU field and the newly added user equipment media access control (UE access control MAC CE) field. Among them. For details about the UE access control MAC CE field, please refer to S202, and this specification will not go into details here.

[0057] Of course, in practical applications, a threshold may be set in advance according to actual conditions. When TBS is greater than the threshold, it can be determined that TBS meets the preset condition, otherwise it does not meet the preset condition.

[0058] S202: Carry the trigger cause in a MAC protocol data unit PDU and send it to a base station device; wherein the MAC PDU includes a plurality of fields organized in sequence; wherein the plurality of fields include a user equipment media access control UEaccess Control MAC control element CE field, a MAC CE field and a MAC service data unit SDU field, and the MACCE field is before the MAC SDU field; the UE access Control MAC CE field is before the MAC SDU field; the UE access Control MAC CE field carries the trigger cause and is used to indicate the trigger cause to the base station device.

[0059] After obtaining the trigger cause, the terminal device can carry the trigger cause in the MAC PDU and send it to the base station device.

[0060] Specifically, the MAC PDU sent by the terminal device to the base station device may include multiple fields organized in sequence, including: a MAC CE field, a MAC SDU field, and a UE access control MAC CE field. For ease of understanding, this specification provides a schematic diagram of the structure of a MAC PDU carrying a triggering factor, such as Figure 3 shown.

[0061] Figure 3 This is a schematic diagram of the structure of a MAC PDU carrying a triggering factor provided in this specification.

[0062] The MAC CE may carry indication information indicating that the base station device has completed resynchronization. In this specification, the indication information may be the C-RNTI of the terminal device. In this case, the MAC CE is a C-RNTI MAC CE.

[0063] The MAC SDU may carry actual communication data of the current communication service. For example, for a user paging service, the corresponding communication data may include the call address of the paging service, and for a terminal uplink main voice service, the corresponding communication data may include voice data.

[0064] The UE access control MAC CE field may carry a triggering cause, which is used to indicate the triggering cause to the base station device.

[0065] In practical applications, the triggering cause (i.e., the communication service that triggers uplink resynchronization) is usually associated with the logical channel group identifier (Logical Channel Group ID, LCGID) or the user equipment access control identifier (UE access ControlID). On this basis, the triggering cause can be characterized by the logical channel group identifier (Logical Channel Group ID, LCGID) and / or the UE access Control ID.

[0066] Therefore, in this specification, the above-mentioned UE access Control MAC CE field may carry LCGID and / or UE access control identifier access Control ID. When the base station device parses the UE access Control MAC CE field, the trigger cause may be determined only based on the LCGID, or only based on the UE access Control ID. Of course, the trigger cause may also be determined in combination with LCGID and UE access Control ID.

[0067] Among them, the logical channel identifier (Logical Channel ID, LCID) of the UE access Control MAC CE field can be set to 42. When the UE access Control MAC CE field carries both LCGID and UE accessControl ID, the total field size of the UE access Control MAC CE field can be 16 bits, its subheader field occupies 8 bits, the LCGID field occupies 3 bits, and the UE access Control ID field occupies 5 bits.

[0068] Furthermore, in the MAC PDU sent by the terminal device to the base station device, the MAC CE field can be placed before the MAC SDU field, and the UE access control MAC CE field can be placed before the MAC SDU field. In this way, when the base station device parses the received MAC PDU, it can first parse the MAC CE field to achieve uplink resynchronization of the terminal device, and then parse the MAC SDU field and process the communication data therein, effectively avoiding the time loss caused by the MAC SDU hanging up and waiting for the parsing result of the MAC CE, and further improving the communication performance.

[0069] The UE access control MAC CE field may be located before the MAC CE field or after the MAC CE field.

[0070] In addition, when the UE side has a need to upload a triggering cause, but the TBS does not meet the preset conditions (such as insufficient to carry the MACCE field, MAC SDU field, and UE access Control MAC CE field), the MAC PDU cannot carry the triggering cause. Therefore, the MAC PDU sent by the terminal device to the base station device may include the MAC CE field and the MAC SDU field, but does not include the UE access Control MAC CE field. In the MAC PDU, the MAC CE field is before the MAC SDU field.

[0071] In actual applications, there are usually some communication scenarios that require the MAC PDU to be kept at a specified field length. In this case, if it is determined that the MAC PDU is configured with a specified field length and there is still sufficient space when the TBS meets the above preset conditions, the terminal device can fill the PADDING field in the MAC PDU to make the MAC PDU field the same as the specified field length.

[0072] It should be noted that the above PADDING field can be a type of MAC CE, namely, PADDING MAC CE. In order to distinguish it from the MAC CE containing C-RNTI (ie, C-RNTI MAC CE), the PADDING field mentioned in this specification can refer to the PADDING MAC CE field.

[0073] When there is an upload trigger requirement and the TBS meets the preset conditions, the fields and order included in the MAC PDU can be: MAC CE field, UE access Control MAC CE field, MAC SDU field and PADDING field.

[0074] In addition, when there is no need to obtain the trigger cause or the TBS does not meet the above preset conditions, if it is determined that the field length of the MAC PDU needs to be maintained at the specified field length and the TBS has remaining padding space, the terminal device can fill the PADDING field in the MAC PDU to keep the MAC PDU at the specified field length, and send the trigger cause to the base station device by carrying the MAC PDU filled with the PADDING field. The MAC PDU at this time includes: MAC CE field, MAC SDU field and PADDING field. The MAC CE field is before the MAC SDU field, and the PADDING field is after the MAC SDU field.

[0075] It should be noted that under the above different communication scenarios and conditions, the length of the specified field that the MAC PDU needs to maintain will also be different.

[0076] Of course, in actual applications, there are some business scenarios that do not require upload trigger factors, but require the MAC SDU field to be before the MAC CE field. In this scenario, if it is determined that the field length of the MAC PDU needs to be maintained at the specified field length, the fields and order included in the MAC PDU can be: MAC SDU, MAC CE, PADDING. If it is determined that the field length of the MAC PDU does not need to be maintained at the specified field length, the fields and order included in the MAC PDU can be: MAC SDU, MAC CE.

[0077] For ease of understanding, this specification provides a schematic diagram of the sending process of a MAC PDU, such as Figure 4 shown.

[0078] Figure 4 A schematic diagram of a MAC PDU sending process provided in this specification.

[0079] from Figure 4It can be seen that when uplink resynchronization is triggered, there are multiple ways to send MAC PDU, including:

[0080] When there is a need to report the triggering cause and the TBS meets the preset conditions, the fields and order included in the MAC PDU are: MAC CE field, UE access control MAC CE field and MAC SDU field;

[0081] When there is a need to report the triggering cause, but the TBS does not meet the preset conditions, the fields and order included in the MAC PDU are: MAC CE field and MAC SDU field;

[0082] When there is no need to report the triggering cause and there is no other need to prepend the MAC SDU, the fields and order included in the MAC PDU are: MAC CE field and MAC SDU field;

[0083] When there is no need to report a triggering cause and there are other needs to put the MAC SDU in front, the fields and order included in the MAC PDU are: MAC SDU field and MAC CE field.

[0084] It should be pointed out that in the actual MAC PDU transmission process, there is also a requirement for the MAC SDU field length. In this case, the MAC PDU field needs to be kept at a specified field length to meet specific format requirements. For the MAC SDU sent in the above situation, the terminal device can determine whether the MAC PDU is configured with a specified field length. If so, the PADDING MAC CE field can be added to the MAC PDU. The field can be at the end of the MAC PDU field. Otherwise, the PADDING MAC CE field is not added.

[0085] The above is an explanation of an uplink resynchronization method provided in this specification based on the perspective of the terminal device. For ease of understanding, the following will further explain an uplink resynchronization method provided in this specification from the perspective of the base station device. The specific steps are shown in 5.

[0086] Figure 5 A schematic diagram of a flow chart of an uplink resynchronization method provided in this specification includes the following steps:

[0087] S501: receiving a MAC PDU sent by a terminal device;

[0088] S502: Parse the fields in the MAC PDU in order;

[0089] S503: When the MAC CE field in the MAC PDU is parsed, uplink resynchronization is performed according to the indication information carried by the MAC CE field;

[0090] S504: When the UE access control MAC CE field in the MAC PDU is parsed, a communication service with the terminal device is performed according to a triggering cause carried by the UE access control MAC CE field;

[0091] S505: When the MAC SDU field in the MAC PDU is parsed, the service data carried by the MAC SDU field is obtained.

[0092] After receiving the MAC PDU sent by the terminal device, the base station device can parse the MAC PDU. When the MAC PDU contains the MAC CE field, MAC SDU field and UE access Control MAC CE field organized in sequence, since the MAC CE field is before the MAC SDU field, the base station device can parse the MAC CE field first.

[0093] In the process of sending MAC PDU, the indication information (such as old C-RNTI) carried in C-RNTI MAC CE will be scrambled by PUSCH as new RNTI. When the base station device obtains MAC PDU, it can parse out the old C-RNTI from it, and then find the previous configuration information of the terminal device based on the old C-RNTI and restore it, so as to complete uplink resynchronization. Among them, the above configuration information may include: network registration and connection information, communication parameters and settings, terminal identity and status information, and application and service configuration, etc. This manual does not make specific restrictions on this.

[0094] When parsing the UE access Control MAC CE field in the MAC PDU, the base station device can parse the trigger cause from the UE access Control MAC CE field, and then execute the communication service with the terminal device.

[0095] When parsing the MAC SDU field in the MAC PDU, the base station device can obtain the service data carried by the MAC SDU field.

[0096] In this process, the base station equipment can allocate communication resources to the terminal equipment based on the triggering factors, such as adjusting the network planning bearer level inactivity timer, MSG3 uplink TBS parameters, etc., so as to provide more reliable, timely, or sufficient resources for the synchronous users, and at the same time count the frequency, delay, and data volume of different resynchronization of UE access control to achieve network optimization between the base station equipment and the terminal equipment. Then, the communication service between the base station equipment and the terminal equipment is executed based on the parsed service data.

[0097] For example, for triggering factors such as user paging, terminal uplink calling signaling, terminal uplink main voice service, terminal key service, etc., the terminal key service often has a higher priority than other services, and the terminal uplink main voice service often has a lower priority than other services. Therefore, when the base station device determines that the triggering factor is the LCGID or UE access Control ID associated with the terminal key service, it can prioritize the allocation of communication resources for it, and when the base station device determines that the triggering factor is the LCGID or UE access Control ID associated with the uplink main voice service, it can reduce the priority of allocating resources to it.

[0098] From the above method, it can be seen that this solution adjusts the assembly order between MAC CE and MAC SDU, and optimizes the processing flow of MAC PUD by the base station equipment. In addition, this solution can report the triggering cause of terminal uplink resynchronization on demand based on the uplink resynchronization requirements of different scenarios, thereby triggering different strategies of the base station and effectively improving communication performance.

[0099] The above are one or more uplink resynchronization methods implemented in this specification. Based on the same idea, this specification also provides a corresponding uplink resynchronization device, such as Figure 6 or Figure 7 shown.
