Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which an embodiment of the present invention is applicable, as shown in fig. 1, including a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: terminal-side devices such as a Mobile phone, a tablet Computer (Tablet Personal Computer), a Laptop (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile internet device (Mobile INTERNET DEVICE, MID), or a wearable device (Wearable Device), it should be noted that the specific type of the terminal is not limited in the embodiments of the present invention. The network-side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, etc., or the network side device may be an Access Point (AP); the base station may also be a network node formed by a Central Unit (CU) together with a plurality of transmission reception points (TRP, transmission Reception Point) which it manages and controls. It should be noted that, in the embodiment of the present invention, the specific type of the network side device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a method for activating repeated transmission according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. The method comprises the steps that a terminal receives an MAC CE sent by network side equipment, wherein the MAC CE comprises RB indication information and logic channel indication information, the RB indication information is used for indicating the RB configured with repeated transmission, and the logic channel indication information is used for indicating the activation state of part or all of logic channels corresponding to the RB configured with repeated transmission.

The RB configured with the retransmission may refer to an RB that has been configured with the retransmission, but is not activated or deactivated, and the RBs are activated or deactivated by the MAC CE.

In addition, the RB indication information described above may indicate that the retransmission is active, and may also indicate that the retransmission is inactive or deactivated. The logical channel indication information may be an activation state indicating a part or all of the logical channels corresponding to each RB, so that it may be determined whether or not those logical channels are activated by using the activation states, and further, whether or not the repeated transmission of the corresponding RBs is activated may be determined by using the activation states of those logical channels, for example: when two or more logical channels corresponding to a certain RB are in an activated state, the repeated transmission of the RB is activated, otherwise, when one logical channel corresponding to the certain RB is in an activated state, the repeated transmission of the RB is not activated.

In addition, in the embodiment of the present invention, the RB configured with repeated transmission may correspond to two or more logical channels.

It should be noted that, in the embodiment of the present invention, the activated state may include two states, that is, activated or deactivated (may also be referred to as not activated).

By the MAC CE, the repeated transmission can be accurately controlled under the condition that one RB configured with repeated transmission corresponds to 2 or more than 2 logic channels, and the resource utilization efficiency can be maximized while the service delay reliability is met. For example: when the logical channel corresponding to a certain RB configured with repeated transmission is 3, 2 or 3 of the logical channels may be indicated by the above logical channel indication information.

As an optional implementation manner, the RB indication information is:

the identity (RB ID) of the RB configured with the repeated transmission.

The RB ID is a unique identifier in a terminal configured by the network side equipment for the RB.

In this embodiment, the RB ID plus logical channel indicating information may be implemented to indicate the activation state of the RB and the activation state of the corresponding logical channel.

In an optional implementation manner, the MAC CE is a variable-length MAC CE, and the MAC sub-header corresponding to the MAC CE includes an LCID indicating the type of the MAC CE and a length indication field, where the length indication field is used to indicate the length of the MAC CE; or alternatively

The maximum length of the variable-length MAC CE may configure the maximum number of RBs that are not repeatedly transmitted, and the length of the MAC CE may be determined according to the current required indication or the number of RBs that need to be activated, so that the overhead of the MAC CE may be saved. The length indication field may indicate 1 byte.

In addition, in the above embodiment, a fixed-length MAC CE may be used, so that the overhead of the MAC sub-header may be saved.

As an optional implementation manner, if the RB indication information is the RB ID of the RB configured with repeated transmission, the activated states of the RBs configured with repeated transmission, which are present in the MAC CE, are all activated.

In this embodiment, it is possible to implement that the RBs configured with repeated transmission, whose active states are all active, are included in the MAC CE, that is, as long as the active states of the RBs configured with repeated transmission, which are included in the MAC CE, are all active. Thereby, overhead of the MAC CE can be reduced and indication of the activation state of the RB can be simply implemented.

Of course, in the embodiment of the present invention, the above is not limited, for example: in some embodiments, the MAC CE may further include RB IDs of RBs configured with repeated transmissions, the RB IDs of which are deactivated in activation states.

As an optional implementation manner, if the RB indication information is the RB ID of the RB configured with repeated transmission, the logic channel indication information is used to indicate respective activation states of all logic channels corresponding to each RB in the RB configured with repeated transmission; or alternatively

In this embodiment, the respective activation states of all the logical channels corresponding to each RB through the above logical channel indication information may be implemented, and the respective activation states of each logical channel may be precisely controlled.

In addition, in this embodiment, it may be further implemented that the logical channel indication information indicates an active state of a part of the logical channels, because in this embodiment, one primary logical channel may be configured for each RB, and the active state of the primary logical channel is active when the RB is active, so that it is not necessary to indicate the primary logical channel, so as to reduce the overhead of the MAC CE.

The specific logic channel sequence may be ordered according to the logic channel number from small to large, or ordered according to the logic channel configuration sequence, or ordered according to the logic channel number in each base station by first arranging the main base station and then arranging the auxiliary base station according to the corresponding base station node. Preferably, the specific logical channel sequence may be preconfigured, or predefined in a protocol, etc.

In this embodiment, since each RB has corresponding logical channel indication information and indicates the activation states of all or part of the logical channels of the RBs according to a specific logical channel sequence, it is not necessary to increase the identification of the logical channels in the logical channel indication information, thereby reducing the overhead of the MAC CE.

It should be noted that the above-described various alternative embodiments may be implemented in combination with each other, and the following illustrates the above-described various alternative embodiments by way of four examples:

Embodiment one: RB ID + all logical channels indication, MAC CE variable length

In this embodiment, all logical channels corresponding to RBs configured with repeated transmission may be deactivated, i.e., there is no always active primary logical channel. The RB ID is a unique in-UE identity configured by the base station for the RB. The MAC CE only comprises RBs which need to be activated or deactivated and configured with repeated transmission, the length is variable, and the maximum length is the maximum number of RBs capable of configuring the repeated transmission. With this MAC CE format, the MAC sub-header contains a length indication field L, which may be 1byte in length. The duplicate transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC subheader.

As shown in fig. 3, one byte corresponds to repeated transmission activation/deactivation of one RB. Wherein the RB ID length is 5 bits, and one RB is configured with at most 3 logical channels, i.e., one PDCP PDU has at most 3 repeated transmissions, and each logical channel corresponds to one bit. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, RB ID1 configures 3 logical channels, and the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5. If the protocol specifies that the logical channel configuration sequence is followed, L1, L2 and L3 in the first byte correspond to LCID1, LCID2 and LCID3 respectively; if the protocol specifies that the logical channel number is from small to large, L1, L2 and L3 in the first byte correspond to LCID2, LCID3 and LCID1 respectively; if the protocol specifies that L1, L2, L3 in the first byte correspond to LCID1, LCID3, and LCID2, respectively, from large to small in terms of logical channel number. If one RB only configures two logical channels, the third logical channel indication domain corresponding to the RB ID, namely L3 is a reserved bit, the base station gNB fills in any value or a fixed value specified by a protocol, and the terminal ignores the bit.

Embodiment two: RB ID + all logical channel indication, MAC CE fixed length

In this embodiment, all logical channels corresponding to RBs configured with repeated transmission may be deactivated, i.e., there is no always active primary logical channel. The RB ID is a unique in-UE identity configured by the base station for the RB. The MAC CE length is fixed to the maximum number of RBs in which repeated transmission can be configured. The MAC CE only contains the ID of the RB which needs to be activated or deactivated and configured with repeated transmission, if the ID is smaller than the maximum RB number which can be configured with repeated transmission, the remaining bytes are reserved bytes, wherein the bit base station configures any value or a value specified by a configuration protocol, and the terminal ignores the partial bytes. With this MAC CE format, the MAC sub-header does not contain a length indication field L, and for the MAC sub-header indicating a fixed-length MAC CE, the repeated transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC sub-header.

As shown in fig. 4, the number of RBs that can be configured as a maximum of 8 for repeated transmission activation/deactivation of one byte corresponds to one RB, so the MAC CE length is 8 bytes. Wherein the RB ID length is 5 bits, and one RB is configured with at most 3 logical channels, i.e., one PDCP PDU has at most 3 repeated transmissions, and each logical channel corresponds to one bit. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, RB ID1 configures 3 logical channels, and the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5. If the protocol specifies that the logical channel configuration sequence is followed, L1, L2 and L3 in the first byte correspond to LCID1, LCID2 and LCID3 respectively; if the protocol specifies that the logical channel number is from small to large, L1, L2 and L3 in the first byte correspond to LCID2, LCID3 and LCID1 respectively; if the protocol specifies that L1, L2, L3 in the first byte correspond to LCID1, LCID3, and LCID2, respectively, from large to small in terms of logical channel number. If one RB only configures two logical channels, the third logical channel indication domain corresponding to the RB ID, namely L3 is a reserved bit, the base station fills in any value or a fixed value specified by a protocol, and the terminal ignores the bit.

Embodiment III: RB ID + indication of partial logical channel, MAC CE variable length

In this embodiment, if one of the logical channels corresponding to the RB configured with the retransmission is always an active primary logical channel, only the deactivatable logical channel indication needs to be included in the retransmission activation/deactivation MAC CE. The RB ID is a unique in-UE identity configured by the base station for the RB. The MAC CE only comprises RBs which need to activate or deactivate the repeated transmission, the length is variable, and the maximum length is the maximum number of RBs which can be configured for the repeated transmission. With this MAC CE format, the MAC sub-header contains a length indication field L, which may be 1byte in length. The duplicate transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC subheader.

As shown in fig. 5, one byte corresponds to repeated transmission activation/deactivation of one RB. Wherein the RB ID length is 5 bits, and one RB is configured with at most 3 logical channels, i.e., one PDCP PDU has at most 3 repeated transmissions, and each deactivatable logical channel corresponds to one bit. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, RB ID1 configures 3 logical channels, the order in RRC signaling is lcid1=6, lcid2=5, lcid3=4, where LCID1 is the primary logical channel, and the domain indication is not indicated by the logical channel. If the protocol specifies that the logical channel configuration sequence is followed, L1 and L2 in the first byte respectively correspond to LCID2 and LCID3; if the protocol specifies that the logical channel number is from small to large, L1 and L2 in the first byte respectively correspond to LCID3 and LCID2; if the protocol specifies that the logical channel number is from large to small, L1 and L2 in the first byte correspond to LCID2 and LCID3, respectively. If one RB only configures two logic channels, the logic channel indication domains L1 and L2 corresponding to the RB ID are reserved bits, the base station fills in any value or fixed value specified by a protocol, and the terminal ignores the bit.

Embodiment four: RB ID + indication of deactivatable logical channel, fixed length

In this embodiment, if one of the logical channels corresponding to the RB configured with the retransmission is always an active primary logical channel, only the deactivatable logical channel indication needs to be included in the retransmission activation/deactivation MAC CE. The RB ID is a unique in-UE identity configured by the base station for the RB. The MAC CE only contains RBs which need to activate or deactivate the repeated transmission, and the length is fixed to be the maximum number of RBs capable of configuring the repeated transmission. With this MAC CE format, the MAC sub-header does not contain a length indication field L, and for the MAC sub-header indicating a fixed-length MAC CE, the repeated transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC sub-header.

As shown in fig. 6, one byte corresponds to repeated transmission activation/deactivation of one RB. Wherein the RB ID length is 5 bits, and one RB is configured with at most 3 logical channels, i.e., one PDCP PDU has at most 3 repeated transmissions, and each deactivatable logical channel corresponds to one bit. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, RB ID1 configures 3 logical channels, the order in RRC signaling is lcid1=6, lcid2=5, lcid3=4, where LCID1 is the primary logical channel, and the domain indication is not indicated by the logical channel. If the protocol specifies that the logical channel configuration sequence is followed, L1 and L2 in the first byte respectively correspond to LCID2 and LCID3; if the protocol specifies that the logical channel number is from small to large, L1 and L2 in the first byte respectively correspond to LCID3 and LCID2; if the protocol specifies that the logical channel number is from large to small, L1, L2 in the first byte correspond to LCID2 and LCID3, respectively. If one RB only configures two logic channels, the logic channel indication domains L1 and L2 corresponding to the RB ID are reserved bits, the base station fills in any value or fixed value specified by a protocol, and the terminal ignores the bit.

As an optional implementation manner, the RB indication information is:

In this embodiment, the RB configured with the retransmission may be indicated by a bitmap, and each bit corresponds to one RB configured with the retransmission. The rules indicated by the Bitmap may be preconfigured or pre-agreed in the protocol, for example: the RB in which the retransmission is configured is indicated in the order of RB IDs from large to small, or the RB in which the retransmission is configured may be indicated in the order of RB IDs from small to large.

The RB configured with the repeated transmission is indicated by the bitmap, so that the overhead of the MAC CE can be saved.

Also, in this embodiment, the MAC CE is a variable-length MAC CE, and the MAC subheader corresponding to the MAC CE includes a logical channel number LCID indicating the type of the MAC CE and a length indication field, where the length indication field is used to indicate the length of the MAC CE; or alternatively

As an optional implementation manner, the bitmap is further configured to indicate an activation state of the RB configured with repeated transmission, where each bit in the bitmap corresponds to an RB ID of the RB configured with repeated transmission, and whether the corresponding RB activates repeated transmission is determined according to a corresponding bit position of 0 or 1.

Since each bit corresponds to one RB configured with repeated transmission, whether the corresponding RB activates repeated transmission can be represented by the value of the bit, for example: 1 determines whether the corresponding RB activates the retransmission or 0 determines whether the corresponding RB activates the retransmission. This can realize that the activation state of the RB configured with the repeated transmission is indicated by a small number of bits.

The RB capable of repeating transmission may be an RB for activating repeating transmission indicated by the bitmap.

In this embodiment, the respective activation states of all the logical channels corresponding to each activated RB through the above logical channel indication information may be implemented, and the respective activation states of each logical channel may be accurately controlled, and only the respective activation states of all the logical channels corresponding to the activated RB may be indicated, so that the overhead of the MAC CE may be reduced.

In addition, in this embodiment, it may be further implemented that the logic channel indication information indicates an activation state of a part of the logic channels, and because in this embodiment, one main logic channel may be configured for each activated RB, where the activation state of the main logic channel is activated when the RB is activated, it is not necessary to indicate the main logic channel, and only the respective activation states of all the logic channels corresponding to the activated RBs need to be indicated, so that the overhead of the MAC CE may be reduced.

In this embodiment, the order of the logical channel indication information may be implemented to correspond to the order in which the bitmap indicates the activated RBs, because the logical channel indication information of the inactive RBs is not included, and thus the activation status of all or part of the logical channels of each activated RB may be accurately indicated.

In this embodiment, the specific logical channel sequence may be referred to the specific logical channel sequence described in the previous embodiment, which is not described herein.

Also, the various alternative embodiments described above may be implemented in combination with one another, and are illustrated below by way of four examples:

fifth embodiment: RB indication of bitmap+all logical channel indication, MAC CE variable length

All logical channels corresponding to RBs configured for repeated transmission in this embodiment may be deactivated, i.e., there is no always active primary logical channel. The 1 st byte of the repeated transmission activation/deactivation MAC CE indicates whether all RBs configured with repeated transmission activate/deactivate the repeated transmission by using a bitmap, and then sequentially indicates whether corresponding logical channels are activated for activating the RBs configured with repeated transmission. The 1 st byte only indicates that the repeated transmission is configured, and the repeated transmission activated/deactivated RBs can be performed, wherein the correspondence between the RBs and the bit of the 1 st byte corresponds to the repeated transmission RB configuration sequence or the sequence of repeated transmission RB numbers from big to small. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, DRB7 is configured with 3 logical channels, the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5. If the protocol specifies that the sequence is configured according to the logic channel, after the DRB7 activates the repeated transmission (the bit position 1 corresponding to the 1 st byte), the corresponding logic channel indication positions L1, L2 and L3 respectively correspond to LCID1, LCID2 and LCID3; if the protocol specifies that the logical channel number is from small to large, L1, L2 and L3 corresponding to the DRB7 respectively correspond to LCID2, LCID3 and LCID1; if the protocol specifies that L1, L2, L3, which correspond to DRB7, correspond to LCID1, LCID3, and LCID2, respectively, from large to small according to the logical channel number. If one RB only configures two logical channels, the third logical channel indication domain corresponding to the RB, namely L3 is a reserved bit, the base station fills in any value or a fixed value specified by a protocol, and the terminal ignores the bit.

As shown in fig. 7, if the base station configures DRB7, DRB6 and DRB5 for UE to perform retransmission, the first 3 bits of the 1 st byte correspond to DRB7, DRB6 and DRB5, and the subsequent bits of the 1 st byte are reserved bits. The base station instructs DRB7 and DRB5 to activate the repeat transmission (i.e. 1 st and 3 rd bit are set to 1), and RB6 to deactivate the repeat transmission (2 nd bit is set to 0); therefore, as shown in fig. 8, the 1 st to 3 rd bits of the 2 nd byte correspond to the 3 logical channels of RB7, and the 4 th to 6 th bits correspond to the 3 logical channels of RB 5.

With this MAC CE format, the MAC sub-header contains a length indication field L, which may be 1byte in length. The duplicate transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC subheader.

In the embodiment of the present invention, the RB may be a data radio bearer (Data Radio Bearer, DRB), but this is not a limitation.

Example six: RB indication+all logical channel indication of bitmap, fixed length

In this embodiment, all logical channels corresponding to RBs configured with repeated transmission may be deactivated, i.e., there is no always active primary logical channel. The 1 st byte of the repeated transmission activation/deactivation MAC CE indicates whether all RBs configured with repeated transmission activate/deactivate the repeated transmission by using a bitmap, and then sequentially indicates whether corresponding logical channels are activated for activating the RBs configured with repeated transmission. The 1 st byte only indicates that the repeated transmission is configured, and the repeated transmission activated/deactivated RBs can be performed, wherein the correspondence between the RBs and the bit of the 1 st byte corresponds to the repeated transmission RB configuration sequence or the sequence of repeated transmission RB numbers from big to small. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, RB7 configures 3 logical channels, and the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5. If the protocol specifies that the sequence is configured according to the logic channel, after the RB7 activates the repeated transmission (the 1 st byte corresponds to the bit position 1), the corresponding logic channel indication positions L1, L2 and L3 respectively correspond to LCID1, LCID2 and LCID3; if the protocol specifies that the logical channel number is from small to large, L1, L2 and L3 corresponding to RB7 respectively correspond to LCID2, LCID3 and LCID1; if the protocol specifies that L1, L2, L3, which correspond to DRB7, correspond to LCID1, LCID3, and LCID2, respectively, from large to small according to the logical channel number. If one RB only configures two logical channels, the third logical channel indication domain corresponding to the RB, namely L3 is a reserved bit, the base station fills in any value or a fixed value specified by a protocol, and the terminal ignores the bit.

As shown in fig. 9, if the base station configures DRB7, DRB6 and DRB5 for UE to perform retransmission, the first 3 bits of the 1 st byte correspond to DRB7, DRB6 and DRB5, and the subsequent bits of the 1 st byte are reserved bits. The base station instructs DRB7 and DRB5 to activate the retransmission (i.e. bit 1, bit 3 is set to 1), and DRB6 to deactivate the retransmission (bit 2 is set to 0); thus, as shown in fig. 10, the 1 st to 3 rd bits of the 2 nd byte correspond to the 3 logical channels of DRB7, and the 4 th to 6 th bits correspond to the 3 logical channels of DRB 5.

With this MAC CE format, the MAC subheader does not contain a length indication field L. The duplicate transmission activation/deactivation MAC CE is indicated with a specific LCID in the MAC subheader.

Embodiment seven: RB indication+deactivatable logical channel indication, variable length of bitmap

In this embodiment, if one of the logical channels corresponding to the RB configured with the retransmission is always an active primary logical channel, only the deactivatable logical channel indication needs to be included in the retransmission activation/deactivation MAC CE. The 1 st byte of the repeated transmission activation/deactivation MAC CE indicates whether all RBs configured with repeated transmission activate/deactivate the repeated transmission by using a bitmap, and then sequentially indicates whether corresponding logical channels are activated for activating the RBs configured with repeated transmission. The 1 st byte only indicates that the repeated transmission is configured, and the repeated transmission activated/deactivated RBs can be performed, wherein the correspondence between the RBs and the bit of the 1 st byte corresponds to the repeated transmission RB configuration sequence or the sequence of repeated transmission RB numbers from big to small. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, DRB7 is configured with 3 logical channels, the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5, where LCID1 is the primary logical channel, always active. If the protocol specifies that the sequence is configured according to the logic channel, after the DRB7 activates repeated transmission (the 1 st byte corresponds to the bit position 1), the corresponding logic channel indication positions L1 and L2 respectively correspond to the LCID2 and the LCID3; if the protocol specifies that the logical channel number is from small to large, L1 and L2 corresponding to the DRB7 respectively correspond to LCID2 and LCID3; if the protocol specifies that the logical channel number is from large to small, L1 and L2 corresponding to DRB7 correspond to LCID3 and LCID2 respectively. If one RB is configured with only two logical channels, the RB has no corresponding logical channel indication field.

As shown in fig. 11, if the base station configures DRB7, DRB6, DRB5 and DRB4 for the UE to perform retransmission, the first 4 bits of the 1 st byte correspond to DRB7, DRB6, DRB5 and DRB4, and the subsequent bits of the 1 st byte are reserved bits. The base station instructs DRB7, DRB5 and DRB4 to activate the retransmission (i.e. bit 1, 3, 4 is set to 1), and DRB6 to deactivate the retransmission (bit 2 is set to 0); thus, as shown in fig. 12, the 1 st and 2 nd bits of the 2 nd byte correspond to the 2 active/inactive retransmission logical channels of DRB7, the 3 rd and 4 th bits correspond to the 2 logical channels of DRB5, and in particular, DRB4 is configured with only two logical channels, and active retransmission means that both logical channels are active without additional indication, so that no subsequent logical channel indication field corresponds to DRB 4.

Example eight: RB indication+deactivatable logical channel indication of bitmap, fixed length

In this embodiment, if one of the logical channels corresponding to the RB configured with the retransmission is always an active primary logical channel, only the deactivatable logical channel indication needs to be included in the retransmission activation/deactivation MAC CE. The 1 st byte of the repeated transmission activation/deactivation MAC CE indicates whether all RBs configured with repeated transmission activate/deactivate the repeated transmission by using a bitmap, and then sequentially indicates whether corresponding logical channels are activated for activating the RBs configured with repeated transmission. The 1 st byte only indicates that the repeated transmission is configured, and the repeated transmission activated/deactivated RBs can be performed, wherein the correspondence between the RBs and the bit of the 1 st byte corresponds to the repeated transmission RB configuration sequence or the sequence from big to small of the RB numbers configured with the repeated transmission. The corresponding relation between the logic channel sequence and the bit is arranged according to the sequence of logic channel configuration or the size of logic channel numbers. For example, DRB7 is configured with 3 logical channels, the order in RRC signaling is lcid1=6, lcid2=4, lcid3=5, where LCID1 is the primary logical channel, always active. If the protocol specifies that the sequence is configured according to the logic channel, after the DRB7 activates repeated transmission (the bit corresponding to the 1 st byte is set to be 1), the corresponding logic channel indication positions L1 and L2 respectively correspond to LCID2 and LCID3; if the protocol specifies that the logical channel number is from small to large, L1 and L2 corresponding to the DRB7 respectively correspond to LCID2 and LCID3; if the protocol specifies that the logical channel number is from large to small, L1 and L2 corresponding to DRB7 correspond to LCID3 and LCID2 respectively. If one RB is configured with only two logical channels, the RB does not need to perform a corresponding logical channel activation indication. In the eighth embodiment, a fixed-length MAC CE format is adopted, the fixed-length MAC CE format is fixed to be 3 bytes, the 1 st byte indicates that the RB of the repeated transmission is activated/deactivated, and the 2 nd and 3 rd bytes indicate that the logical channel of the RB of the repeated transmission is activated sequentially. The unused bits are reserved bits and may be padded with any value or protocol specified value, such as 0. After the UE receives the MAC CE, the reserved domain is ignored.

As shown in fig. 13, if the base station configures DRB7, DRB6, DRB5 and DRB4 for the UE to perform retransmission, the first 4 bits of the 1 st byte correspond to DRB7, DRB6, DRB5 and DRB4, and the subsequent bits of the 1 st byte are reserved bits. The base station instructs DRB7, DRB5 and DRB4 to activate the retransmission (i.e. bit 1, 3, 4 is set to 1), and DRB6 to deactivate the retransmission (bit 2 is set to 0); thus, as shown in fig. 14, the 1 st and 2 nd bits of the 2 nd byte correspond to the 2 active/inactive retransmission logical channels of DRB7, the 3 rd and 4 th bits correspond to the 2 logical channels of DRB5, and in particular, DRB4 is configured with only two logical channels, and active retransmission means that both logical channels are active without additional indication, so that no subsequent logical channel indication field corresponds to DRB 4.

As an optional implementation manner, if the terminal is connected to a plurality of network side devices, the MAC CE sent by each network side device only includes RB indication information and logic channel indication information of the MAC entity that sends the MAC CE.
