[0123] MAC subPDU including padding.

[0124] Wherein, each MAC subPDU needs to include 1 subheader.

[0125] In the embodiments of the present disclosure, the dual connectivity (DC) is introduced as follows:

[0126] The terminal can be configured with two cell groups at the same time, namely:

[0127] Master Cell Group (MCG): including at least 1 primary cell (PCell). In addition, it can include 1 or more secondary cells (SCell).

[0128] Secondary Cell Group (SCG): including at least 1 primary secondary cell (PSCell). In addition, it can include 1 or more SCell.

[0129] Wherein, the network node for managing MCG is the master node (MN), and the network node for managing SCG is the secondary node (SN). Wherein, the PCell and the PSCell can be collectively referred to as a special cell (SpCell).

[0130] In the embodiments of the present disclosure, the semi-persistent resource configuration is introduced as follows:

[0131] In order to support faster data management, a semi-persistent resource configuration method is provided for uplink data, including:

[0132] Configured Grant (CG): used for uplink data transmission.

[0133] Wherein, the CG includes the following types:

[0134] Configured Grant Type-1 (CGT-1): The uplink resource configuration provides the periodicity of uplink resource and the specific allocation of uplink time-frequency resource through a radio resource control (RRC) message. After receiving the configuration, the terminal directly uses the configured uplink resource to send uplink data (i.e., the uplink resource is activated immediately after RRC configuration).

[0135] Configured Grant Type-2 (CGT-2): The RRC message configures the periodicity of uplink resource, and the physical downlink control channel (PDCCH) control signaling activates and indicates the specific allocation of uplink time-frequency resource. The terminal needs to use the configured uplink resource to send uplink data after the PDCCH control signaling activates the uplink resource configuration.

[0136] In addition, a semi-persistent resource configuration method is provided for downlink data, including:

[0137] Semi-Persistent Scheduling (SPS): The RRC message configures the periodicity of downlink resource, and the PDCCH control signaling activates and indicates the specific allocation of downlink time-frequency resource. The terminal needs to use the configured downlink resource to receive downlink data after the PDCCH control signaling activates the downlink resource configuration.

[0138] In the embodiments of the present disclosure, the radio link control (RLC) entity is introduced as follows:

[0139] The RB of the terminal has a corresponding RLC entity for data transmission and reception. The types of RLC entities include the following:

[0140] Transparent Mode (TM): The RLC data does not have a packet header, and is directly transmitted through the RLC layer;

[0141] Unacknowledged Mode (UM): The data transmitted by the RLC layer does not require the sending end to receive the confirmation information of the receiving end.

[0142] Acknowledged Mode (AM): The data transmitted by the RLC layer requires the sending end to receive the confirmation information of the receiving end.

[0143] In some embodiments, when the terminal's transceiving data packet type (e.g., data size and service type) is of a specified type (e.g., transparent MAC PDU type), the MAC PDU format still needs to include a large amount of control auxiliary information, such as MAC CEs and padding bits, etc., resulting in a large amount of signaling loss, affecting data transceiving efficiency, and affecting spectrum usage.

[0144] To reduce the loss of control information during data transceiving and improve data transceiving efficiency, the present disclosure provides a communication method, a terminal, a network device, a system, and a storage medium.

[0181] The uplink resource type can comprise, but is not limited to, at least one of the following: a (semi-persistent) configured uplink resource type; a dynamically scheduled uplink resource type.

[0182] The configured uplink resource type can comprise, but is not limited to, any one of the following: Type-1 (e.g. Configured Grant Type-1); Type-2 (Configured Grant Type-2).

[0183] The dynamically scheduled uplink resource type can comprise, but is not limited to: an uplink grant dynamically indicated by a downlink control information (DCI) of a PDCCH.

[0184] The uplink resource configuration information can comprise, but is not limited to, at least one of the following: a configured uplink resource configuration identifier; configured uplink time domain resource information; configured uplink frequency domain resource information.

[0185] The configured uplink time domain resource information can comprise, but is not limited to, at least one of the following: a starting time domain resource position; a number of continuous time domain resources; a period.

[0186] The configured uplink frequency domain resource information can comprise, but is not limited to: cell information used to determine the uplink frequency domain resource.

[0190] Exemplarily, the first resource comprises a downlink resource.

[0191] Exemplarily, the first resource comprises a time domain resource and / or a frequency domain resource.

[0192] When the first resource comprises a downlink resource, the configuration information can comprise at least one of the following: a downlink resource type; and downlink resource configuration information.

[0193] The downlink resource type can comprise, but is not limited to, at least one of the following: a (semi-persistent) configured downlink resource type; and a dynamically scheduled downlink resource type.

[0194] The configured downlink resource type can comprise, but is not limited to, at least one of the following: an SPS resource.

[0201] The cell type identifier can comprise, but is not limited to, at least one of the following: a PCell, an SCell, a PSCell, and a SpCell.

[0202] The above is only an example, and the disclosure does not limit the specific content of the first resource information.

[0203] When the configuration information comprises the first resource information, it can mean that the type of data packets transmitted and / or received when data is transmitted and / or received on the first resource is the first type.

[0204] For example, considering that the priority of the MAC CE is higher than that of the data packets of the first type, in order to avoid the MAC CE from preoccupying the first resource, the first resource configured by the configuration information can be limited to not being used for transmitting the MAC CE, or the first resource configured by the configuration information can be limited to being used only for transmitting the data packets of the first type.

[0205] In one example, the configuration information can include a first type. Wherein, the first type can be a type of RLC entity of the first type of data packet.

[0206] Exemplarily, the RLC entity of the first type can adopt a transparent mode, i.e., TM mode.

[0207] For example, the configuration information indicates that the data of DRB-1 uses the first type of data packet for transmission, and the RLC entity corresponding to the DRB-1 is of RLC TM.

[0208] For another example, the configuration information indicates that the data of DRB-1 in logical channel-1 (LCH-1) uses the first type of data packet for transmission, and the RLC entity corresponding to the DRB-1 in the LCH-1 is of RLC TM.

[0209] In one example, the configuration information can include a first data amount. Wherein, the first data amount is the number of the first type of data packet transmitted each time.

[0210] Exemplarily, the first data amount can be 1.

[0211] That is, the service corresponding to the configuration information can transmit 1 first type of data packet each time.

[0212] For example, the configuration information indicates that the data of DRB-1 uses the first type of data packet for transmission, and when the transmission data amount of the DRB-1 is 1 (e.g., one MAC SDU or one PDCP SDU), the first type of data packet can be used for transmission.

[0213] The above is only an exemplary description, and the specific content of the configuration information is not limited in the disclosure.

[0214] In some embodiments, the name of the configuration information is not limited, and can be interchangeable with data configuration information, data type configuration information, etc.

[0215] In some embodiments, the related configuration of the first type of data packet can be bound or associated with a semi-persistent resource.

[0216] Exemplarily, the network device 102 provides a semi-persistent resource configuration to support faster data management. In the embodiment of the present disclosure, the network device 102 can bind or associate the provided semi-persistent resource with the first type of data packet when providing the semi-persistent resource configuration. So that the terminal 101 transmits uplink data using the first type of data packet on the semi-persistent resource, and / or receives downlink data on the semi-persistent resource, and the type of the downlink data packet is the first type, thereby further reducing the loss of control information during data transmission and reception, especially the loss of dynamic control information, improving the efficiency of data transmission and reception while supporting faster data management.

[0217] In step S2102, the network device 102 sends DCI to the terminal 101.

[0218] In some embodiments, the terminal 101 receives the DCI.

[0219] In some embodiments, the DCI can be used to dynamically schedule the terminal 101 to transmit and / or receive the first type of data packet.

[0220] In some embodiments, the related configuration of the first type of data packet can be bound or associated with the dynamically scheduled resource, wherein the dynamic scheduling of the resource can be performed through the DCI.

[0221] In some embodiments, the DCI can include but is not limited to at least one of the following: first indication information; second indication information.

[0222] In one example, the first indication information can be used to indicate that the type of the transmitted and / or received data packet is the first type.

[0223] In one example, the second indication information can be used to indicate first data information, and the first data is the data transmitted by the first type of data packet. The specific content of the first data information has been introduced in the foregoing step S2101, and will not be repeated here.

[0224] In one example, the DCI dynamically schedules a first resource, wherein the specific content of the first resource information has been introduced in the foregoing step S2101, and will not be repeated here.

[0225] Exemplarily, the first indication information can be used to indicate that the type of the data packet transmitted and / or received using the first resource is the first type.

[0226] Exemplarily, the second indication information can be used to indicate first data information transmitted using the first resource.

[0227] In step S2103, the terminal 101 transmits the first type of data packet to the network device 102.

[0228] In some embodiments, the network device 102 receives the first type of data packet.

[0229] In some embodiments, the terminal 101 can send the first type of data packet to the network device 102 based on the configuration information.

[0230] In some embodiments, if the uplink data to be sent matches the first data configured by the configuration information, the uplink data is encapsulated into the first type of data packet, and then the first type of data packet is sent to the network device 102. The first data is the data transmitted by the first type of data packet. The uplink data can be submitted by a specified bearer, and the specified bearer can be a bearer corresponding to the first resource.

[0231] In some embodiments, if the resource occupied by the uplink data to be sent matches the first resource configured by the configuration information, the uplink data is encapsulated into the first type of data packet, and then the first type of data packet is sent to the network device 102. The uplink data can be submitted by a specified bearer, and the specified bearer can be a bearer corresponding to the first resource. The first resource is the resource for transmitting the first type of data packet.

[0232] In some embodiments, if the uplink data to be sent matches the first data configured by the configuration information, and the resource occupied by the uplink data to be sent matches the first resource configured by the configuration information, the uplink data is encapsulated into the first type of data packet, and then the first type of data packet is sent to the network device 102. The first data is the data transmitted by the first type of data packet. The uplink data can be submitted by a specified bearer, and the specified bearer can be a bearer corresponding to the first resource. The first resource is the resource for transmitting the first type of data packet.

[0233] The above is only an exemplary description, and the disclosure does not limit the manner in which the terminal 101 sends the first type of data packet to the network device 102.

[0234] For the network device 102, it can submit the data packet received on the first resource configured by the configuration information to the first bearer after unpacking, and the first bearer unpacks according to the first type of data packet format. The first bearer is a bearer corresponding to the first resource.

[0235] In step S2104, the network device 102 sends the first type of data packet to the terminal 101.

[0236] In some embodiments, the terminal 101 receives the first type of data packet.

[0237] In some embodiments, if the downlink data to be sent matches the first data configured by the configuration information, the network device 102 can send the first type of data packet to the terminal 101 after encapsulating the downlink data into the first type of data packet. The first data is the data transmitted by the first type of data packet.

[0238] In some embodiments, if the resource occupied by the downlink data to be sent matches the first resource configured by the configuration information, the network device 102 can send the first type of data packet to the terminal 101 after encapsulating the downlink data into the first type of data packet. The first resource is the resource for transmitting the first type of data packet.

[0239] In some embodiments, if the downlink data to be sent matches the first data configured by the configuration information, and the resource occupied by the downlink data to be sent matches the first resource configured by the configuration information, the network device 102 can send the first type of data packet to the terminal 101 after encapsulating the downlink data into the first type of data packet. The first resource is the resource for transmitting the first type of data packet.

[0240] For the terminal 101, it can submit the data packet received on the first resource configured by the configuration information to the first bearer after unpacking the data packet, and the first bearer unpacks the data packet according to the first type of data packet format. The first bearer is the bearer corresponding to the first resource.

[0241] For example, the network device 102 configures the LCH-1 of the terminal 101 to use the first type of data packet when receiving through the SPS configuration-1. When the terminal 101 receives data on the physical message shared channel (PDSCH) corresponding to the SPS configuration-1, it determines that the type of the received data packet is the first type, and submits the data packet to the DRB corresponding to the LCH-1, and the DRB unpacks the data packet according to the first type of data packet format to obtain the content of the SDU.

[0242] For another example, the network device 102 configures the LCH-1 of the terminal 101 to receive downlink data through DCI scheduling. When the DCI indicates the first data information corresponding to the LCH-1 as the data allocated for downlink at the same time, the terminal determines that the type of the data packet received on the LCH-1 is the first type, and submits the data packet to the DRB corresponding to the LCH-1, and the DRB unpacks the data packet according to the first type of data packet format.

[0243] In some embodiments, the names of information and the like are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "code point", "bit", "data", "program", "chip", and the like can be replaced with each other.

[0244] In some embodiments, terms such as "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI", and the like can be replaced with each other.

[0245] In some embodiments, "acquire", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive", and the like can be replaced with each other, and can be interpreted as receiving from other subjects, acquiring from protocols, acquiring from higher layers, obtaining by self-processing, autonomously implementing, and the like.

[0246] In some embodiments, terms such as "send", "transmit", "report", "issue", "transmit", "bidirectional transmission", "send and / or receive", and the like can be replaced with each other.

[0247] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2104. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, step S2103 can be implemented as an independent embodiment, steps S2102+S2103 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, steps S2102+S2104 can be implemented as an independent embodiment, steps S2101+S2103 can be implemented as an independent embodiment, steps S2101+S2104 can be implemented as an independent embodiment, steps S2101-S2104 can be implemented as an independent embodiment, but not limited thereto.

[0248] In some embodiments, step S2101 and step S2102 can be executed alternatively or both. For example, if the terminal 101 does not need to receive and / or transmit the first type of data packet dynamically scheduled by DCI, step S2102 can not be executed. For another example, if the terminal 101 receives and / or transmits the first type of data packet scheduled by DCI through the configuration information issued by the DCI, step S2101 can not be executed. For another example, if the network device 102 first sends the configuration information and then schedules the terminal 101 to receive and / or transmit the first type of data packet through DCI, steps S2101 and S2102 can both be executed.

[0249] In some embodiments, steps S2101 to S2104 are optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0250] In some embodiments, the execution order of steps S2101 to S2104 is not limited.

[0251] In the above embodiments, the terminal transmits and / or receives the first type of data packet based on the configuration information sent by the network device, and the first type of data packet can only include service data without control information, thereby reducing the loss of control information during data transmission and reception, improving data transmission and reception efficiency, improving spectrum utilization, and having high availability.

[0252] In some embodiments, the above step S2101 can be executed alone. For example, when the related configuration of the first type of data packet is bound or associated with the semi-persistent resource, the network device 102 can provide the terminal 101 with the semi-persistent resource configuration, wherein the semi-persistent resource configuration can include but is not limited to at least one of the following: the configured semi-persistent resource; and indication information, which can be used to indicate that when the semi-persistent resource is used for data transmission and reception, the type of data packet is the first type. Accordingly, when the semi-persistent resource is not needed for data transmission and reception, the above steps S2102 to S2104 can be omitted. This reduces the loss of control information during data transmission and reception, especially the loss of dynamic control information, and has high availability.

[0375] Wherein, further, the RLC entity type of the DRB corresponding to the “transparent MAC PDU” configuration information can be limited to RLC TM. For example, the network side configures the terminal to use “transparent MAC PDU” for DRB-1 (or, DRB-1 of logical channel-1), then the RLC entity type of the DRB corresponding to the “transparent MAC PDU” configuration information is RLC TM.

[0376] Wherein, further, the number of data transmitted by the service corresponding to the “transparent MAC PDU” configuration information each time can be limited to 1. For example, the network side configures the terminal to use “transparent MAC PDU” for DRB-1 (or, DRB-1 of logical channel-1), then only when the current data amount of the DRB is 1 data packet, for example, 1 MAC SDU (or, 1 PDCP SDU), can “transparent MAC PDU” be used.

[0377] Wherein, further, when a “transparent MAC PDU” is received (Uplink grant) or transmitted (Downlink assignment) through dynamic scheduling, the content of the dynamic scheduling information (e.g., DCI) can include at least one of the following:

[0378] “transparent MAC PDU” type indication;

[0379] "Data information using "transparent MAC PDU". Wherein the "Data information using "transparent MAC PDU" is the same as above.

[0380] Step S4102: According to the configuration information in step S4101, the terminal receives or transmits data through "transparent MAC PDU".

[0381] For uplink data transmission, when the data type sent by the terminal matches the "Data information using "transparent MAC PDU", and the uplink resource type for sending the data matches the "Uplink resource information using "transparent MAC PDU", the terminal uses "transparent MAC PDU" for data transmission.

[0382] For example, the network configures the terminal's logical channel-1 to use "transparent MAC PDU" when sending data through configuredGrantConfiguration-1. Then, when the terminal's logical channel-1 has data to send, and the data of "logical channel-1" is sent through the uplink resource configured by configuredGrantConfiguration-1, the terminal uses "transparent MAC PDU" to send the data of "logical channel-1" through the uplink resource configured by configuredGrantConfiguration-1.

[0383] For another example, the network configures the terminal's logical channel-1 to use "transparent MAC PDU" when sending data through Dynamic grant. Then, when the terminal's logical channel-1 has data to send, and the DCI indicates the uplink grant while indicating that the "Data information using "transparent MAC PDU" is the data corresponding to logical channel-1, the terminal uses "transparent MAC PDU" to send the data of "logical channel-1" through the uplink resource indicated by the DCI.

[0384] For downlink data reception, when the downlink resource type received by the terminal matches the "downlink resource information using transparent MAC PDU" specified in the "transparent MAC PDU configuration information for downlink reception", the terminal uses the "transparent MAC PDU" for downlink data reception. Further, the terminal submits the received downlink data to the bearer corresponding to the "transparent MAC PDU" downlink resource information.

[0385] For example, the network configures the terminal to use the "transparent MAC PDU" when receiving the logical channel-1 through the spsConfiguration-1. Then, when receiving data through the PDSCH corresponding to the spsConfiguration-1, the terminal uses the "transparent MAC PDU" for data reception, and submits the MAC SDU to the DRB corresponding to the logical channel-1.

[0386] For example, the network configures the terminal to use the "transparent MAC PDU" when receiving the logical channel-1 through the DCI scheduling. Then, when the DCI indicates the Downlink assignment and indicates the "data information using transparent MAC PDU" for the data corresponding to the logical channel-1, the terminal uses the "transparent MAC PDU" for reception, and submits the MAC SDU to the DRB corresponding to the logical channel-1.

[0387] Further, it can be limited that when the terminal transmits the DRB data through the "transparent MAC PDU", the uplink resource corresponding to the "transparent MAC PDU" cannot transmit the MAC CE.
