Description

TECHNICAL FIELD

[0001] The present specification relates to the technical field of communication, and particularly relates to an uplink resynchronization method and device. BACKGROUND

[0002] In the process of mobile network communication, the terminal device needs to re-enter the network after being disconnected from the network due to the terminal device not communicating with the network for a long time, or reasons such as power-off, network switching, network failure, etc. In this case, the configuration information of the terminal device in the base station device needs to be resynchronized, that is, the terminal device that re-enters the network is restored to the previous configuration. In this way, the base station device can allocate communication resources to the terminal device based on the configuration information of the uplink resynchronization, so that the terminal device can reconnect to the network and communicate based on the configuration information of the uplink resynchronization.

[0003] However, after the configuration information of the terminal device is resynchronized, the trigger reason for the uplink resynchronization is usually not determined. In this case, the base station device is difficult to determine the communication service after the uplink resynchronization, and cannot effectively meet the communication demand. SUMMARY

[0013] Optionally, the trigger cause is carried in a MAC PDU and sent to a base station device, and specifically comprises:

[0014] If it is determined that the MAC PDU is configured with a specified field length, a padding PADDING field is filled in the MAC PDU, so that the field length of the MAC PDU is the same as the specified field length, and the trigger cause is carried in the MAC PDU filled with the PADDING field and sent to the base station device.

[0015] The present specification provides an uplink resynchronization method, which is applied to a base station device, and comprises:

[0016] Receiving a MAC PDU sent by a terminal device;

[0017] Parsing fields in the MAC PDU in sequence;

[0018] When a MAC CE field in the MAC PDU is parsed, uplink resynchronization is performed according to indication information carried by the MAC CE field;

[0020] When a MAC SDU field in the MAC PDU is parsed, service data carried by the MAC SDU field is obtained.

[0021] The present specification provides an uplink resynchronization device, which comprises:

[0022] An obtaining module, configured to obtain a trigger cause of current uplink resynchronization to be performed when it is determined that a TBS satisfies a preset condition;

[0023] The sending module is configured to carry the trigger cause in a MAC PDU and send the MAC PDU to the base station device, wherein the MAC PDU comprises a plurality of fields organized in sequence, wherein the plurality of fields comprise a UE access Control MAC CE field, a MAC CE field, and a MAC SDU field, the MAC CE field is before the MAC SDU field, the UE access Control MAC CE field is before the MAC SDU field, and the UE access Control MAC CE field carries the trigger cause and is used to indicate the trigger cause to the base station device.

[0024] The specification provides an uplink resynchronization device, comprising:

[0025] The receiving module is configured to receive a MAC PDU sent by a terminal device.

[0026] The parsing module is configured to parse fields in the MAC PDU in sequence.

[0027] The resynchronization module is configured to, when a MAC CE field in the MAC PDU is parsed, perform uplink resynchronization according to indication information carried by the MAC CE field.

[0034] As can be seen from the above method, in the uplink resynchronization of the configuration information of the terminal device, the MAC PDU sent to the base station device carries not only the MAC CE field and the MAC SDU field, but also the trigger cause information of the uplink resynchronization. In this way, after receiving the MAC PDU, the base station device can not only perform uplink resynchronization of the terminal device based on the analysis result of the MAC CE field, but also perform the current communication service according to the trigger cause information carried by the MAC PDU, so as to fully meet the communication demand of the current communication service.

[0043] For the purpose, technical solutions and advantages of the specification to be clearer, the technical solutions of the specification will be described clearly and completely in the following with reference to the specific embodiments of the specification and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the specification, rather than all the embodiments. Based on the embodiments in the specification, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the specification.

[0044] Medium Access Control (MAC) Protocol Data Unit (PDU) as a unit of data transmission between peer-to-peer levels plays an important role in the process of data communication. In order to facilitate understanding, the specification provides a structure schematic diagram of a conventional MAC PDU, as shown in Figure 1 .

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

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

[0047] In the actual process of communication, the MAC sub PDU can be processed independently, and the UL MAC sub PDU containing MAC CE(s) is located after the UL MAC sub PDU containing MAC SDU.

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

[0049] In addition, since the MAC CE is located after the MAC SDU, when the base station device parses the MAC PDU, the MAC SDU will be parsed first, and 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, the parsing result of the next MAC subPDU (i.e., the MAC CE) still needs to be suspended and waited.

[0050] The technical solutions provided by the embodiments of the present specification will be described in detail below with reference to the accompanying drawings.

[0051] Figure 2 A flowchart of an uplink resynchronization method provided in the present specification includes the following steps:

[0052] S201: When it is determined that the transport block size TBS meets the preset condition, the trigger cause of the current to-be-executed uplink resynchronization is obtained.

[0053] In general, there are various reasons for the base station device (such as GNB) to perform uplink resynchronization on the configuration information of the terminal device (such as User Equipment (UE)), 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 base station coverage area, or switching from one network type to another network type), the terminal configuration information being lost or damaged, network updating or software upgrading, 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 according to the identification information, so as to realize the 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 performs communication services such as user paging, terminal uplink calling signaling, terminal uplink main voice service, terminal key service, etc., the uplink resynchronization will be triggered.

[0055] When the UE side has a demand for uploading a triggering cause, the terminal device can first determine whether a transport block size (TBS) satisfies a preset condition, and when it is determined that the preset condition is satisfied, the terminal device can obtain a triggering cause for uplink resynchronization. The triggering cause is used to indicate that the uplink resynchronization is triggered when the terminal device performs a communication service.

[0056] In the present specification, the above preset condition can mean that the total size of the UE access Control MAC CE field, the MAC CE field and the MAC SDU field is not greater than the TBS, at which time the TBS is sufficient to carry the MAC CE field, the MAC SDU field and the newly added UE access Control MAC CE field. For details of the content related to the UE access Control MAC CE field, please see S202, which will not be described in detail here.

[0057] Of course, in actual application, a threshold value can also be set in advance according to actual conditions, and when the TBS is greater than the threshold value, it can be determined that the TBS satisfies the preset condition, otherwise it does not satisfy.

[0058] S202: carrying the triggering cause in a MAC protocol data unit PDU and sending 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 UE access Control MAC control element CE field, a MAC CE field and a MAC service data unit SDU field, the MAC CE 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 triggering cause, which is used to indicate the triggering cause to the base station device.

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

[0060] Specifically, in the MAC PDU sent by the terminal device to the base station device, a plurality of fields organized in sequence can be included, which include the MAC CE field, the MAC SDU field and the UE access Control MAC CE field. In order to facilitate understanding, the present specification provides a structure diagram of a MAC PDU carrying a triggering cause, as shown in Figure 3

[0061] ​Figure 3 A structure diagram of a MAC PDU carrying a triggering factor is provided in the present specification.

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

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

[0064] The UE access Control MAC CE field can carry a triggering factor, which is used to indicate the triggering factor to the base station device.

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

[0066] Therefore, in the present specification, the UE access Control MAC CE field described above can carry an LCGID and / or a UE access Control ID. When the base station device parses the UE access Control MAC CE field, the triggering factor can be determined only according to the LCGID, only according to the UE access Control ID, or in combination with the LCGID and the UE access Control ID.

[0067] The logical channel identifier (LCID) of the UE access Control MAC CE field can be set as 42. When the LCGID and the UE access Control ID are carried in the UE access Control MAC CE field, the total field size of the UE access Control MAC CE field can be 16 bits, the subheader field occupies 8 bits, the LCGID field occupies 3 bits, and the UE access Control ID field occupies 5 bits.

[0068] Further, in the MAC PDU sent by the terminal device to the base station device, the MAC CE field can be before the MAC SDU field, and the UE access Control MAC CE field can be before the MAC SDU field. In this way, when the base station device parses the received MAC PDU, the MAC CE field can be parsed first to realize the uplink resynchronization of the terminal device, and the MAC SDU field is parsed and the communication data therein is processed, effectively avoiding the time loss caused by the suspension of the MAC SDU waiting for the parsing result of the MAC CE, and further improving the communication performance.

[0069] The UE access Control MAC CE field can be before the MAC CE field or after the MAC CE field.

[0070] In addition, when there is a demand for uploading a trigger cause on the UE side, but the TBS does not meet the preset condition (such as insufficient to carry the MAC CE field, the MAC SDU field, and the UE access Control MAC CE field), the MAC PDU cannot carry the trigger cause at this time. Therefore, the MAC PDU sent by the terminal device to the base station device can 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 application, there are usually some communication scenarios that require the MAC PDU to maintain 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 under the condition that the TBS meets the above preset condition, 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, i.e., PADDING MAC CE, in order to distinguish from the MAC CE containing C-RNTI, i.e., C-RNTI MAC CE, the PADDING field mentioned in this specification can refer to PADDING MAC CE.

[0073] When there is a need to upload the trigger cause, and the TBS meets the preset condition, the fields and order contained 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-mentioned preset condition, if it is determined that the field length of the MAC PDU needs to be kept as a specified field length and there is a remaining padding space in the TBS, the terminal device can fill the PADDING field into the MAC PDU to keep the MAC PDU at the specified field length, and carry the trigger cause in the MAC PDU filled with the PADDING field to the base station device. At this time, the MAC PDU contains: MAC CE field, MAC SDU field and PADDING field. Wherein 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 in the above different communication scenarios and conditions, the specified field length required to be kept by the MAC PDU will also be different.

[0076] Of course, in actual application, there are also some service scenarios that do not need to upload the trigger cause, 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 kept as a specified field length, the fields and order contained in the MAC PDU can be: MAC SDU, MAC CE, PADDING, and if it is determined that the field length of the MAC PDU does not need to be kept as a specified field length, the fields and order contained in the MAC PDU can be: MAC SDU, MAC CE.

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

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

[0079] From Figure 4It can be seen that when the uplink resynchronization is triggered, there are multiple sending modes of MAC PDU, including:

[0080] When there is a demand to report a trigger cause and the TBS meets the preset condition, the fields included in the MAC PDU and the order are: a MAC CE field, a UE access Control MAC CE field, and a MAC SDU field.

[0081] When there is a demand to report a trigger cause, but the TBS does not meet the preset condition, the fields included in the MAC PDU and the order are: a MAC CE field and a MAC SDU field.

[0082] When there is no demand to report a trigger cause, and there is no other demand to preposition a MAC SDU, the fields included in the MAC PDU and the order are: a MAC CE field and a MAC SDU field.

[0083] When there is no demand to report a trigger cause, and there is a demand to preposition a MAC SDU, the fields included in the MAC PDU and the order are: a MAC SDU field and a MAC CE field.

[0084] It should be noted that in the actual process of transmitting the MAC PDU, the length of the MAC SDU field is also required, in which case the fields of the MAC PDU need to be maintained at a specified field length to meet the specific format requirements. For the MAC SDU sent in the above case, the terminal device can determine whether the MAC PDU is configured with a specified field length, if so, a PADDING MAC CE field can be added to the MAC PDU, which can be at the end of the fields of the MAC PDU, otherwise no PADDING MAC CE field is added.

[0085] The above is a description of an uplink resynchronization method provided in the specification from the perspective of a terminal device. In order to facilitate understanding, the following will further describe an uplink resynchronization method provided in the specification from the perspective of a base station device, and the specific steps are shown in 5.

[0086] Figure 5 The flowchart of an uplink resynchronization method provided in the specification includes the following steps:

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

[0088] S502: sequentially parsing the fields in the MAC PDU;

[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, communication services with the terminal device are performed according to the trigger cause carried by the UE access Control MAC CE field.

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

[0092] After the base station device receives the MAC PDU sent by the terminal device, the MAC PDU can be parsed. When the MAC PDU contains the MAC CE field, the MAC SDU field, and the UE access Control MAC CE field organized in order, because the MAC CE field is before the MAC SDU field, the base station device can first parse the MAC CE field.

[0093] In the process of sending the MAC PDU, the indication information (such as old C-RNTI) carried in the C-RNTI MAC CE is scrambled by the PUSCH as new RNTI. When the base station device obtains the MAC PDU, the old C-RNTI can be parsed therefrom. Then, based on the old C-RNTI, the configuration information of the terminal device before is found and restored, thereby completing the uplink resynchronization. The above-mentioned configuration information can include network registration and connection information, communication parameters and settings, terminal identity and state information, and application and service configuration, which are not limited in the specification.

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

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

[0096] In this process, the base station device can allocate communication resources based on the trigger cause for the terminal device, such as adjusting the network bearer level inactivity timer, MSG3 uplink TBS parameter, etc., to provide more reliable, more timely, or more sufficient resources for synchronous users, while statistics UE access Control different resynchronization frequency, latency, data volume, to realize the network optimization between the base station device and the terminal device. Further based on the analysis of the business data to perform communication services with the terminal device.

[0097] For example, for user paging, terminal uplink caller signaling, terminal uplink main voice service, terminal key service and other trigger causes, the terminal key service often has higher priority than other services, and the terminal uplink main voice service often has lower priority than other services, so when the base station device determines the LCGID or UE access Control ID associated with the trigger cause of the terminal key service, it can preferentially allocate communication resources to it, and when the base station device determines the LCGID or UE access Control ID associated with the trigger cause of the uplink main voice service, it can reduce the priority of allocating resources to it.

[0098] As can be seen from the above method, the present scheme adjusts the assembly order between MAC CE and MAC SDU, and optimizes the processing flow of MAC PUD by the base station device. Moreover, the present scheme can report the trigger cause of terminal uplink resynchronization on demand based on the uplink resynchronization demand of different scenarios, thereby triggering different strategies of the base station, effectively improving the communication performance.

[0099] The above is one or more embodiments of the uplink resynchronization method of the present specification. Based on the same idea, the present specification also provides a corresponding uplink resynchronization device, as shown in Figure 6 or Figure 7 .
