[0003] The present application belongs to the field of communication technology, and specifically relates to an information transmission method, device, terminal and network side equipment. BACKGROUND

[0004] In related technologies, when the resources of an uplink (UL) grant for new data transmission scheduled by a network are insufficient to carry all the data to be newly transmitted of a logical channel, if a buffer status report (BSR) is triggered, the terminal will preferentially use the resources of the UL grant to carry the BSR, and then carry part of the remaining data, that is, the transmission priority of the BSR is higher than that of the data to be newly transmitted. However, preferential transmission of the BSR will cause a relatively high probability of delay transmission of some important service data, resulting in poor information transmission effect.

[0063] For the convenience of understanding, some contents related to the embodiments of the present application are explained as follows:

[0064] 1、BSR

[0065] When a user equipment (UE, i.e., terminal) and a network (e.g., a base station) interact data, in order to assist the network to perform uplink scheduling, the UE needs to inform the network of the amount of uplink data to be transmitted (Buffer Status) in the buffer of the UE. After obtaining the amount of uplink data to be transmitted, the network can allocate appropriate uplink resources for the UE. The reporting process of Buffer Status is called BSR (Buffer Status Reporting).

[0066] At a time point, a UE can have uplink data of multiple services to be transmitted, and these data have different Quality of Service (QoS) requirements. In order to allow the network to implement different scheduling strategies for data with different QoS requirements, the UE can map the uplink data to different logical channels according to the configuration of the network, different logical channels correspond to the same or different scheduling priorities, and the priority of the logical channel is configured by the network (NW). The network can map one or more logical channels with similar QoS requirements to a logical channel group. In NR, the UE supports a maximum of 16 logical channels (Logical Channel, LCH) and 8 logical channel groups (Logical Channel Group, LCG). The UE reports BSR according to the logical channel group, and the purpose of the UE reporting BSR according to the logical channel group (rather than the logical channel) is to reduce the overhead of BSR reporting.

[0067] The UE reports BSR with the logical channel group as the basic granularity, that is, the amount of uplink data to be transmitted of all logical channels in each logical channel group (LCG) is added and summed, and the obtained result is mapped to a BS index according to the mapping table defined by the protocol (the mapping table indicates the correspondence between the BS value and the index). In the process of BSR, the UE reports the index value corresponding to the BS value of each LCG. In NR, the BS index value has two formats, and the lengths are 5 bits or 8 bits.

[0068] Table 1 gives an example of the mapping relationship between the BS index value and the BS value: according to the example, when the BS value is 50 bytes, the corresponding BS index value is 6.

[0069] Table 1

[0070] A triggering condition of BSR is as follows:

[0071] When a new data packet arrives in the buffer of the UE, and the following two conditions are met at the same time, the logical channel to which the new data packet belongs will trigger BSR:

[0072] - the logical channel to which the new data belongs has no data buffered (i.e. is empty);

[0073] - the priority of the above logical channel is higher than all other logical channels with data buffered or all other logical channels have no data buffered (i.e. are empty).

[0074] 2. Uplink data scheduling

[0075] When a UE receives an uplink (UL) grant from the network to schedule uplink new transmission, the UE Medium Access Control (MAC) layer needs to determine the content to be transmitted on the uplink resources scheduled by the UL grant according to the size of the UL grant and the priority of the data and control signaling to be transmitted. In NR, the priority rule used by the related art is as follows:

[0076] Logical channels shall be prioritised in accordance with the following order (highest priority listed first):

[0077] C-RNTI MAC CE or data from UL-CCCH;

[0078] Configured Grant Confirmation MAC CE or BFR MAC CE or Multiple Entry Configured Grant Confirmation MAC CE;

[0079] Sidelink Configured Grant Confirmation MAC CE;

[0080] LBT failure MAC CE;

[0081] MAC CE for SL-BSR prioritized;

[0082] BSR MAC CE, with exception of BSR included for padding;

[0083] Single Entry PHR MAC CE or Multiple Entry PHR MAC CE;

[0084] MAC CE for the number of Desired Guard Symbols;

[0085] MAC CE for Pre-emptive BSR;

[0086] MAC CE for SL-BSR;

[0087] Data from any Logical Channel, except data from UL-CCCH;

[0088] MAC CE for Recommended bit rate query;

[0089] BSR MAC CE included for padding;

[0090] SL-BSR MAC CE included for padding.

[0091] It can be seen that in the related art, when there is a BSR MAC CE (except padding BSR MAC CE) and data from a logical channel other than UL-CCCH to be transmitted, the UE should preferentially transmit the BSR MAC CE.

[0092] Meanwhile, the related art describes an exception:

[0093] All triggered BSRs may be cancelled when the UL grant(s) can accommodate all pending data available for transmission but is not sufficient to additionally accommodate the BSR MAC CE plus its subheader.

[0094] The information transmission method, device and related equipment provided by the embodiments of the present application are described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.

[0095] Referring to FIG. 2, FIG. 2 is a flowchart of an information transmission method according to an embodiment of the present application. As shown in FIG. 2, the information transmission method comprises the following steps:

[0096] In step 101, the terminal transmits data on the uplink grant resource according to a first transmission priority rule.

[0097] The first transmission priority rule comprises:

[0098] In the case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal and can carry all the data to be transmitted by a first logical channel (LCH), the transmission priority of the data to be transmitted by the first LCH is higher than that of a triggered buffer status report (BSR) medium access control (MAC) control element (CE).

[0099] The data to be transmitted by the terminal comprises data to be transmitted by at least two LCHs, and the first LCH is an LCH with the highest logical channel priority among the at least two LCHs.

[0100] In addition, insufficient to carry can also be described as unable to carry or cannot carry.

[0101] In addition, can carry can also be described as can carry or sufficient to carry.

[0102] In addition, the uplink grant resource can also be described as a resource scheduled by an uplink grant (UL grant).

[0103] In addition, the resource of the uplink grant, unless otherwise specified, refers to the uplink resource for new transmission scheduled by the uplink grant.

[0104] In an embodiment, the resource of the uplink grant (UL grant) can carry all the data to be transmitted of the first LCH, which means that the resource of the uplink grant can carry the data of the first LCH and the corresponding protocol header overhead, which can include the header overhead of the protocol layer such as Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), or MAC. That is, the size of the resource of the uplink grant is greater than or equal to the sum of the data size of the first LCH and the protocol header size corresponding to the data of the first LCH.

[0105] In an embodiment, the transmission priority of the data to be transmitted of the first LCH is higher than the transmission priority of the triggered BSR MAC Control Element (CE), which means that the terminal preferentially transmits all the data to be transmitted of the first LCH.

[0106] For example, in the case that the resource of the uplink grant is insufficient to carry all the data to be transmitted of the first LCH, the triggered BSR MAC CE, and the MAC subheader thereof, the terminal preferentially transmits all the data to be transmitted of the first LCH on the resource of the uplink grant.

[0107] For example, in the case that the resource of the uplink grant is insufficient to carry all the data to be transmitted of the first LCH, the triggered BSR MAC CE, and the MAC subheader thereof, the terminal transmits the data of the first LCH on the resource of the uplink grant and does not transmit the BSR MAC CE and the MAC subheader thereof.

[0108] It should be noted that the embodiments of the present application only focus on the transmission priority relationship between the BSR MAC CE and the logical channel (the logical channel corresponding to the Signaling Radio Bearer (SRB) and the Data Radio Bearer (DRB)) for carrying user data. With the introduction of new MAC CE, the priority rules in the related art can be increased or adjusted; the priority information of irrelevant MAC CE in the related art is only an example, not a limitation.

[0109] In addition, unless otherwise specified, in the embodiments of the present application, the data to be transmitted refers to the high layer data to be newly transmitted at the MAC layer.

[0110] In addition, the data to be transmitted can also be described as data to be sent, or data to be newly transmitted, or pending data.

[0111] In addition, the data to be transmitted of the terminal can refer to the data to be newly transmitted of all logical channels of the terminal. The data to be newly transmitted of all logical channels can refer to the high layer data to be newly transmitted or retransmitted at the MAC layer.

[0112] In the embodiments of the present application, the newly transmitted corresponds to the retransmission, unless otherwise specified, the newly transmitted by default refers to the initial transmission of HARQ at the MAC layer; the retransmission refers to the retransmission of HARQ at the MAC layer.

[0113] It should be noted that, since the transmission priority of the BSR included for padding is lower than that of any data of the logical channel, unless otherwise specified, the BSR MAC CE in the embodiments of the present application can all refer to the BSR MAC CE other than the BSR included for padding by default.

[0114] In addition, the UL grant can be a dynamic grant or a configured grant, and the embodiments of the present application do not limit whether the resource of the UL grant is a single transmission time-frequency resource or a periodic transmission time-frequency resource.

[0115] In an implementation manner, when the size of the UL grant resource for scheduling a new transmission (which can be briefly described as a new transmission) is not enough to simultaneously carry all the data to be newly transmitted of the terminal and the triggered BSR, the terminal determines the data carried on the UL grant resource according to the following method:

[0116] If the UL grant can carry all the data of the high priority logical channel, but cannot simultaneously carry the BSR and the data of the high priority logical channel, and cannot carry all the data to be transmitted, the terminal transmits the data of the high priority logical channel, and cancels the BSR triggered by the high priority logical channel at the same time;

[0117] Otherwise, the terminal transmits the BSR, and if there is a remaining UL grant resource, continues to carry part of the data of the high priority logical channel, wherein the high priority logical channel can refer to the LCH with the highest logical channel priority.

[0118] In one implementation, when the terminal assembles a protocol data unit (PDU) (such as a MAC PDU) to be transmitted based on an UL grant, there are N LCHs in total with data to be transmitted (N>1, and LCH 1 is the LCH with the highest priority among the N LCHs), and if there is also a triggered BSR at this time:

[0119] If the size of the UL grant cannot simultaneously carry the BSR MAC CE and all data of LCH 1, but can carry all data of LCH 1, the terminal preferentially carries all data of LCH 1 on the UL grant, and does not carry the BSR MAC CE;

[0120] Otherwise: the terminal preferentially carries the BSR MAC CE on the UL grant.

[0121] For example, when the terminal packages data for transmission on resources corresponding to the UL grant, LCH 1 and LCH 2 both have data to be transmitted, and there is a triggered BSR, and LCH 1 is the LCH with the highest logical channel priority. Assuming that the size of the UL grant that can be carried is A, the size required to carry all data to be transmitted of LCH 1 (including the corresponding protocol header overhead, such as a MAC subheader) is B, the size required to carry all data to be transmitted of LCH 2 (including the corresponding protocol header overhead, such as a MAC subheader) is C, and the size required to carry the BSR MAC CE (including the corresponding protocol header overhead, such as a MAC subheader) is D, where B, C, and D are all greater than 0; if A>=B and A<B+D, the terminal preferentially carries all data of LCH 1 to the UL grant. Optionally, in the case where there is still remaining resources in the UL grant, the terminal carries other data on the UL grant.

[0122] In the embodiments of the present application, when the UL grant resources are insufficient to simultaneously transmit the BSR and all data to be transmitted, if the UL grant can transmit all data of the LCH with the highest priority, the UL grant preferentially transmits the data of the LCH with the highest priority to reduce the transmission delay; otherwise, the terminal preferentially transmits the BSR to indicate the amount of data to be transmitted to the network side.

[0123] In an implementation, the terminal can determine whether to enable the highest priority data priority function based on network side configuration, and the highest priority data priority function can be enabled per cell, or per terminal, or per LCG, or per bearer, or per LCH. For example, the highest priority data priority function is enabled for a cell, which means that the function is enabled for all terminals in the cell that support the highest priority data priority function. The highest priority data priority function means that the terminal transmits data on the uplink granted resource according to the first transmission priority rule. The terminal transmits data on the uplink granted resource according to the first transmission priority rule only when the highest priority data priority function is enabled.

[0124] It should be noted that when the network side schedules UL grant resources for new transmission, the resources are sufficient to carry all data to be newly transmitted (the data to be newly transmitted refers to the data to be newly transmitted in the initial transmission of the hybrid automatic repeat request (HARQ) of the MAC layer), but insufficient to carry the triggered BSR at the same time. According to the mechanism in the related art, the terminal carries all data to be newly transmitted using the UL grant and cancels the triggered BSR; when the network side schedules UL grant resources for new transmission, the resources are insufficient to carry all data to be newly transmitted. If a BSR is triggered, according to the mechanism in the related art, the terminal carries the BSR using the UL grant first, and then carries part of the remaining data; that is, the priority of the BSR is higher than that of the data to be newly transmitted.

[0125] The problem of the mechanism in the related art is that if the terminal currently has N logical channels with data to be newly transmitted, the priorities of the N logical channels are different, the UL grant resources are sufficient to carry all data of the highest priority logical channel, but insufficient to carry the BSR and all data of the highest priority logical channel. According to the mechanism in the related art, the terminal will preferentially transmit the BSR and part of the data of the highest priority logical channel; this will cause the remaining data of the highest priority logical channel that is not transmitted to be delayed, resulting in a decrease in user experience. In particular, for ultra-reliable and low latency communication (URLLC) services, additional delays may be caused by BSR transmission.

[0126] In the embodiments of the present application, in the case that the uplink granted resource is insufficient to carry all data to be newly transmitted by the terminal, and the uplink granted resource can carry all data to be transmitted of the first LCH, by preferentially carrying the first LCH, the probability of delaying the transmission of important service data can be reduced, thereby improving the user experience.

[0127] It should be noted that in the related art, when there are N logical channels with different priorities and data to be transmitted, and a BSR is triggered, according to the mechanism in the related art, the terminal needs to transmit the BSR MAC CE first; unless the UL grant can transmit all the data to be transmitted. However, for an UL grant, if it is sufficient to carry all the data of the highest priority logical channel, but insufficient to carry all the data of the highest priority logical channel and the BSR MAC CE; according to the mechanism in the related art, the terminal will preferentially transmit the BSR MAC CE, and all or part of the data of the highest priority logical channel will be left for subsequent transmission. This will increase the delay of the data in the highest priority logical channel.

[0128] In the embodiment of the present application, the terminal transmits data on the uplink grant resource according to a first transmission priority rule; the first transmission priority rule includes: in the case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first logical channel LCH, the transmission priority of the data to be transmitted by the first LCH is higher than the transmission priority of the triggered buffer status report BSR medium access control MAC control element CE; wherein the data to be transmitted by the terminal includes data to be transmitted by at least two LCHs, and the first LCH is the LCH with the highest logical channel priority among the at least two LCHs. In this way, in the case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first LCH, by preferentially carrying the first LCH, the probability of delaying the transmission of important service data can be reduced, thereby improving the information transmission effect.

[0129] Optionally, the terminal transmits data on the uplink grant resource according to a first transmission priority rule, including:

[0130] In the case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first logical channel LCH, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource.

[0131] In an implementation, in the case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first logical channel LCH, if the uplink grant resource is insufficient to carry all the data to be transmitted by the first LCH and the BSR MAC CE and its MAC subheader, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, and the terminal does not transmit the BSR MAC CE and its MAC subheader.

[0132] In an implementation, in a case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first logical channel LCH, if the uplink grant resource can carry all the data to be transmitted by the first LCH and the BSR MAC CE and the MAC subheader thereof, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, and the terminal transmits the BSR MAC CE and the MAC subheader thereof.

[0133] It should be noted that the terminal can determine a low-priority LCH (or bearer) or a high-priority LCH (or bearer) based on network side configuration; when data transmission of the high-priority LCH (or bearer) only causes delay in reporting of the BSR corresponding to the low-priority LCH (or bearer), the data transmission of the high-priority LCH (or bearer) is prioritized.

[0134] In this implementation, in a case that the uplink grant resource is insufficient to carry all the data to be transmitted by the terminal, and the uplink grant resource can carry all the data to be transmitted by the first logical channel LCH, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, and the data to be transmitted by the first LCH is usually important service data, thereby reducing the probability of delay in transmission of important service data, improving information transmission effect, and improving user experience.

[0135] Optionally, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, including:

[0136] In a case that the uplink grant resource is insufficient to carry all the data to be transmitted by the first LCH and the BSR MAC CE and the MAC subheader thereof, the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, and the terminal does not transmit the BSR MAC CE and the MAC subheader thereof.

[0137] It should be noted that the terminal does not transmit the BSR MAC CE and the MAC subheader thereof on the uplink grant resource. Since the terminal transmits the data to be transmitted by the first LCH on the uplink grant resource, even if the BSR MAC CE is reported, in the reported BSR MAC CE, the data to be transmitted corresponding to the first LCH is 0 byte, and the BSR index corresponding thereto is 0, so the terminal can not transmit the BSR MAC CE, and the transmission of high-priority data will not be affected.

[0138] In the embodiment, if the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH and the BSR MAC CE and the MAC subheader thereof, the terminal transmits the data to be transmitted of the first LCH on the resources of the uplink grant, and the terminal does not transmit the BSR MAC CE and the MAC subheader thereof. In this way, high-priority data can be transmitted preferentially, the impact of delaying the transmission of the BSR MAC CE is lower than the impact of delaying the data of the LCH1, the transmission delay of high-priority data can be reduced, and user experience can be improved.

[0139] Optionally, the terminal transmits on the resources of the uplink grant according to the first transmission priority rule, and the method further includes:

[0140] In a case where the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH, the terminal transmits the BSR MAC CE on the resources of the uplink grant.

[0141] In an embodiment, the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH can mean that the resources of the uplink grant are too small (or insufficient) to carry all the data to be transmitted of the first LCH, or the maximum amount of data allowed to be transmitted of the first LCH is limited, so that all the data to be transmitted of the first LCH cannot be carried. For example, the maximum amount of data allowed to be transmitted can be limited based on the transmission fairness between LCHs.

[0142] For example, when there are multiple LCHs with data to be transmitted, if the resources are always occupied in order of the absolute priority of the LCHs from high to low, the low-priority LCHs can always fail to obtain a transmission opportunity. Therefore, a token bucket mechanism can be introduced, and each LCH corresponds to a token bucket. Tokens are added to the token bucket according to the prioritized bit rate (PBR). For example, the PBR of LCH1 is 5 Mbps, and the PBR of LCH2 is 1 Mbps. The logical channel priority of LCH1 is higher than that of LCH2. When the UL grant resources are allocated:

[0143] If there are 8M bits of tokens in the bucket corresponding to LCH1 and 0.5M bits of tokens in the bucket corresponding to LCH2; the UL grant can carry 9M bits of data; LCH1 has 9M bits of data. At this time, the terminal allocates UL grant resources in the following manner: first, allocate resources carrying 8M bits of data to LCH1, and at the same time, reduce the tokens in the bucket corresponding to LCH1 to 0; then allocate resources carrying 0.5M bits of data to LCH2, and at the same time, reduce the tokens in the bucket corresponding to LCH2 to 0; then allocate the remaining 0.5M bits of resources to LCH1, at which time the resources are exhausted, and LCH1 still has data that has not been allocated resources. In this case, it also belongs to: the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH (i.e., LCH1).

[0144] In this embodiment, in the case that the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH, the terminal transmits the BSR MAC CE on the resources of the uplink grant, so that when the resources of the uplink grant are insufficient to carry all the data to be transmitted of the first LCH, the terminal preferentially transmits the BSR MAC CE on the resources of the uplink grant, so that the network side device can allocate appropriate uplink resources to the terminal according to the BSR MAC CE reported by the terminal to transmit the remaining data to be transmitted of the terminal.

[0145] Optionally, the method further comprises:

[0146] The terminal receives first configuration information sent by the network side device, and the first configuration information is used to configure the terminal to apply the first transmission priority rule or configure the terminal not to apply the first transmission priority rule.

[0147] The terminal transmits on the resources of the uplink grant according to the first transmission priority rule, comprising:

[0148] If the first configuration information is used to configure the terminal to apply the first transmission priority rule, the terminal transmits on the resources of the uplink grant according to the first transmission priority rule.

[0149] In an embodiment, the first configuration information can be used to turn on a target feature or not to turn on the target feature, the terminal that turns on the target feature can apply the first transmission priority rule to transmit on the resources of the uplink grant; the terminal that does not turn on the target feature does not apply the first transmission priority rule to transmit on the resources of the uplink grant, and the terminal can apply a second transmission priority rule to transmit on the resources of the uplink grant, for example.

[0150] In one embodiment, the terminal can start the target feature based on network side configuration; the terminal that does not start the target feature transmits the BSR MAC CE according to the mechanism in the related art; unless the UL grant can carry all the data to be newly transmitted of the LCH of the terminal.

[0151] In one embodiment, the UE receives the configuration signaling of the network side (NW) side, and the configuration signaling is used to start the target feature, and the highest priority logical channel with data to be transmitted is transmitted before the BSR MAC CE transmission under the target feature.

[0152] The UE has two LCHs (such as LCH1 and LCH2) with data to be transmitted, wherein the priority of LCH1 is higher than that of LCH2.

[0153] At time T1, the UE has an uplink resource UL grant available: the UL grant can be a dynamic grant or a configured grant, and the present application does not limit whether the UL grant is a single transmission time-frequency resource or a periodic transmission time-frequency resource.

[0154] When the UE packetizes for transmission on the resource corresponding to the UL grant, both LCH1 and LCH2 have data to be transmitted, and there is a triggered BSR: the UE preferentially transmits the data of LCH1.

[0155] Suppose the data size that can be carried by the UL grant is A; the size required to carry all the data of LCH1 (including the corresponding protocol header overhead, such as the MAC subheader) is B; the size required to carry all the data of LCH2 (including the corresponding protocol header overhead, such as the MAC subheader) is C; the size required to carry the BSR MAC CE (including the corresponding protocol header overhead, such as the MAC subheader) is D; wherein B, C, and D are all greater than 0.

[0156] If A >= B and A < B + D, the UE preferentially carries all the data of LCH1 on the UL grant, and in the case that there is still a remaining UL grant, the UE carries other data on the UL grant.

[0157] In this way, the high-priority data can be preferentially transmitted. Since the unsent BSR MAC CE only indicates that the NW has data to be transmitted of the low-priority LCH (in this embodiment, it indicates that LCH2 has data to be transmitted), the impact of the delayed indication is lower than the impact of the delayed data of LCH1.

[0158] In this embodiment, the NW configures to apply the target feature to all the highest priority logical channels, and in this embodiment, the transmission of the highest priority data is prior to the BSR function.

[0159] In an embodiment, the UE receives a configuration signaling from the NW side, which is used to turn on a target feature, under which a highest priority logical channel with data to be transmitted is transmitted before a BSR MAC CE; the NW also configures a low priority logical channel list for the UE, such as LCH2 and LCH3.

[0160] The UE has three LCHs (such as LCH1, LCH2 and LCH3) with data to be transmitted, wherein the priority of LCH1 is higher than that of LCH2 and LCH3.

[0161] At time T1, the UE has an uplink resource UL grant available: the UL grant can be a dynamic grant or a configured grant, and the present embodiment does not limit whether the UL grant is a single transmission time-frequency resource or a periodic transmission time-frequency resource.

[0162] When the UE groups packets for transmission on the resource corresponding to the UL grant, LCH1 and LCH2 both have data to be transmitted, and there is a triggered BSR: the UE preferentially transmits the data of LCH1.

[0163] Suppose the data size that can be carried by the UL grant is A; the size required to carry all data of LCH1 (including the corresponding protocol header overhead, such as a MAC subheader) is B; the size required to carry all data of LCH2 (including the corresponding protocol header overhead, such as a MAC subheader) is C; and the size required to carry a BSR MAC CE (including the corresponding protocol header overhead, such as a MAC subheader) is D; wherein B, C and D are all greater than 0.

[0164] If A >= B and A < B + D, and other LCHs (i.e. LCH2) with data to be transmitted are all LCHs in the low priority logical channel list configured by the NW in step 1, the UE preferentially carries all data of LCH1 onto the UL grant, and in the case that there is still remaining resource on the UL grant, the UE carries other data using the remaining resource.

[0165] In this way, high priority data can be guaranteed to be transmitted. Since the unsent BSR MAC CE only indicates that the NW has low priority LCHs (configured by the NW in step 1) with data to be transmitted (in the present embodiment, this means that LCH2 has data to be transmitted), the impact of the delayed indication is lower than the impact of the delayed data of LCH1.

[0166] In this embodiment, the terminal receives first configuration information sent by the network side device, and if the first configuration information is used to configure the terminal to apply the first transmission priority rule, the terminal transmits data on the uplink granted resource according to the first transmission priority rule. In this way, the terminal can apply or not apply the first transmission priority rule based on the configuration of the network side device, thereby improving the flexibility of information transmission.

[0167] Optionally, the method further comprises:

[0168] If the first configuration information is used to configure the terminal to not apply the first transmission priority rule, the terminal transmits data on the uplink granted resource according to a second transmission priority rule, which is different from the first transmission priority rule.

[0169] In this embodiment, if the first configuration information is used to configure the terminal to not apply the first transmission priority rule, the terminal transmits data on the uplink granted resource according to a second transmission priority rule. In this way, the terminal can transmit data to be transmitted according to the first transmission priority rule or according to the second transmission priority rule based on the configuration of the network side device, thereby improving the flexibility of information transmission.

[0170] Optionally, the method further comprises:

[0171] The terminal receives second configuration information sent by the network side device, and the second configuration information is used to configure the terminal to apply the first transmission priority rule to the transmission of a target LCH or to configure the terminal to not apply the first transmission priority rule to the transmission of the target LCH.

[0172] The second configuration information can include indication information of the target LCH, which indicates that when the target LCH is an LCH with the highest logical channel priority, the transmission priority of the target LCH is higher than the transmission priority of the BSR MAC CE; or the indication information of the target LCH indicates that when the target LCH is an LCH with the highest logical channel priority, if the uplink granted resource is insufficient to carry all data to be transmitted by the terminal and the uplink granted resource can carry all data to be transmitted by the target LCH, the data to be transmitted by the target LCH is preferentially transmitted on the uplink granted resource.

[0173] For example, the indication information of the target LCH can include a number, an index, or an identifier of the target LCH. The second configuration information can configure or indicate the target LCH through the indication information of the target LCH.

[0174] The target LCH can include one or more LCHs, so that the network side can configure whether the first transmission priority rule is applied to the terminal according to the LCH; or the target LCH can include all LCHs of one or more LCGs, so that the network side can configure whether the first transmission priority rule is applied to the terminal according to the LCG.

[0175] In an embodiment, the terminal transmits on the resource of the uplink grant according to the first transmission priority rule, including: if the target LCH includes the first LCH, and the second configuration information is used to configure the terminal to apply the first transmission priority rule to the transmission of the target LCH, the terminal transmits on the resource of the uplink grant according to the first transmission priority rule.

[0176] In an embodiment, the second configuration information can be used to turn on or not turn on the target feature for the target LCH, and for the terminal with the target feature turned on for the target LCH, if the target LCH includes the first LCH, the first transmission priority rule can be applied to transmit on the resource of the uplink grant.

[0177] In an embodiment, the terminal turns on the feature for LCH1 based on the network side configuration; and for the LCH (such as LCH3) without the feature turned on, even if the highest priority logical channel has data to be transmitted, the terminal should preferentially carry the BSR MAC CE on the UL grant. For example, LCH3 and LCH1 have data to be transmitted at the same time, the priority of LCH3 is higher than that of LCH1, the network side does not turn on the feature for LCH3, and the terminal preferentially carries the BSR MAC CE on the UL grant.

[0178] In an embodiment, the UE receives the configuration signaling of the network side, and the configuration signaling is used to turn on the target feature for LCH1. When LCH1 is the highest priority logical channel with data to be transmitted under the target feature turned on, LCH1 is transmitted before the BSR MAC CE.

[0179] The UE has two LCHs (such as LCH1 and LCH2) with data to be transmitted, wherein the priority of LCH1 is higher than that of LCH2.

[0180] At time T1, the UE has an uplink resource UL grant available: the UL grant can be a dynamic grant or a configured grant, and the application embodiments do not limit whether the UL grant is a single transmission time-frequency resource or a periodic transmission time-frequency resource.

[0181] In the case that the UE packetizes data for transmission on the resources corresponding to the UL grant, both LCH1 and LCH2 have data to transmit, and there is a triggered BSR, the UE transmits LCH1 first.

[0182] Assume that the data size that can be carried by the UL grant is A; the size required to carry all data of LCH1 (including the corresponding protocol header overhead, such as MAC subheader) is B; the size required to carry all data of LCH2 (including the corresponding protocol header overhead, such as MAC subheader) is C; the size required to carry the BSR MAC CE (including the corresponding protocol header overhead, such as MAC subheader) is D; wherein B, C, D are all greater than 0;

[0183] If A >= B and A < B+D, the UE carries all data of LCH1 first on the UL grant, and does not transmit the BSR MAC CE on the UL grant.

[0184] In this way, high-priority data can be transmitted first. Since the BSR MAC CE that is not transmitted only indicates that the NW has data to transmit for a low-priority LCH (in this embodiment, LCH2), the impact of the delayed indication is lower than the impact of the delayed data of LCH1.

[0185] In this implementation, the NW configures the target feature to be applied to a specified LCH, i.e., if a PDU to be transmitted is generated based on the UL grant, the specified LCH has the highest priority among all LCH channels that have new data to transmit, the target feature is applied.

[0186] In this implementation, the terminal receives second configuration information transmitted by the network side device, and if the target LCH includes the first LCH and the second configuration information is used to configure the terminal to apply the first transmission priority rule to transmission of the target LCH, the terminal transmits on the resources of the uplink grant according to the first transmission priority rule. In this way, the network side device can configure the terminal to apply the first transmission priority rule or not to apply the first transmission priority rule according to LCH or LCG, and the configuration flexibility is higher.

[0187] Optionally, in the case that the second configuration information is used to configure the terminal to apply the first transmission priority rule to transmission of the target LCH, the terminal transmits on the resources of the uplink grant according to the first transmission priority rule, including: if the target LCH includes the first LCH, the terminal transmits on the resources of the uplink grant according to the first transmission priority rule; or the method further includes: if the target LCH does not include the first LCH, the terminal transmits on the resources of the uplink grant according to a second transmission priority rule;

[0188] Or,

[0189] In a case where the second configuration information is used for configuring that the terminal does not apply the first transmission priority rule to transmission of the target LCH, the method further includes:

[0190] If the target LCH includes the first LCH, the terminal transmits according to a second transmission priority rule on resources of the uplink grant;

[0191] The second transmission priority rule is different from the first transmission priority rule.

[0192] In an implementation, the second configuration information can be used for enabling or not enabling a target feature for a target LCH. For a terminal that enables the target feature for the target LCH, if the target LCH does not include the first LCH, the first transmission priority rule is not applied for transmission on resources of the uplink grant. For example, a second transmission priority rule can be applied for transmission on resources of the uplink grant.

[0193] In an implementation, a UE receives configuration signaling on a network side. The configuration signaling is used for enabling a target feature for an LCH1 (or a bearer corresponding to the LCH1). When the LCH1 is a highest-priority logical channel with data to be transmitted in a case where the target feature is enabled, the LCH1 is transmitted before a BSR MAC CE.

[0194] There are two LCHs (such as LCH1 and LCH2) with data to be transmitted in the UE. The priority of the LCH2 is higher than that of the LCH1.

[0195] At time T1, the UE has uplink resources UL grant available. The UL grant can be a dynamic grant or a configured grant. The present application does not limit whether the UL grant is a single transmission time-frequency resource or a periodic transmission time-frequency resource. When the UE packetizes data for transmission on resources corresponding to the UL grant, the LCH1 and the LCH2 both have data to be transmitted, and there is a triggered BSR: the UE preferentially transmits the BSR.

[0196] This is because the priority of the LCH2 is higher than that of the LCH1. Therefore, the UE should preferentially transmit the LCH2. Meanwhile, the network does not enable the target feature for the LCH2. Therefore, the transmission priority of the BSR is higher than that of data in the LCH2.

[0197] In this way, it can be ensured that high-priority data is preferentially transmitted.

[0198] In this embodiment, the NW configures to apply the target feature to the specified LCH, i.e. if the target feature is applied when generating the PDU to be transmitted based on the UL grant, the specified LCH has the highest priority among all LCH channels with new data to be transmitted.

[0199] In this embodiment, if the target LCH does not include the first LCH, the terminal transmits on the resource of the uplink grant according to the second transmission priority rule; or if the target LCH includes the first LCH and the second configuration information is used to configure the terminal not to apply the first transmission priority rule to the transmission of the target LCH, the terminal transmits on the resource of the uplink grant according to the second transmission priority rule; in this way, only when the network side configures the first transmission priority rule to be applied to the LCH with the highest logical channel priority, the terminal applies the first transmission priority rule, otherwise, the terminal applies the second transmission priority rule, thereby ensuring that the data to be transmitted of the LCH with the highest logical channel priority is transmitted in priority.

[0200] Optionally, the terminal transmits on the resource of the uplink grant according to the second transmission priority rule, comprising:

[0201] In the case that the resource of the uplink grant can carry all the data to be transmitted of the terminal, and the resource of the uplink grant is insufficient to carry all the data to be transmitted of the terminal and the BSR MAC CE and its corresponding MAC subheader, the terminal does not carry the BSR MAC CE on the resource of the uplink grant;

[0202] Or,

[0203] In the case that the resource of the uplink grant is insufficient to carry all the data to be transmitted of the terminal, or the resource of the uplink grant can carry all the data to be transmitted of the terminal and the BSR MAC CE and its corresponding MAC subheader, the terminal carries the BSR MAC CE on the resource of the uplink grant.

[0204] In one implementation, the second transmission priority rule can be described as: the BSR MAC CE is not carried on the resource of the uplink grant in the case that the resource of the uplink grant can carry all the data to be transmitted by the terminal and is insufficient to carry all the data to be transmitted by the terminal and the BSR MAC CE and the corresponding MAC subheader; otherwise, the BSR MAC CE is carried on the resource of the uplink grant; or, the second transmission priority rule can be described as: all triggered BSRs can be cancelled when the UL grant(s) can accommodate all pending data available for transmission but is not sufficient to additionally accommodate the BSR MAC CE plus its subheader.

[0205] In this implementation, the terminal does not carry the BSR MAC CE on the resource of the uplink grant in the case that the resource of the uplink grant can carry all the data to be transmitted by the terminal and the resource of the uplink grant is insufficient to carry all the data to be transmitted by the terminal and the BSR MAC CE and the corresponding MAC subheader; otherwise, the terminal carries the BSR MAC CE on the resource of the uplink grant. In this way, when the resource of the uplink grant is insufficient to carry all the data to be transmitted by the terminal, the terminal preferentially transmits the BSR MAC CE on the resource of the uplink grant, so that the network side device can allocate an uplink resource of a proper size to the terminal according to the BSR MAC CE reported by the terminal to transmit all the data to be transmitted by the terminal.

[0206] The embodiments of the present application can make the highest priority logical channel (usually used to carry services with high delay requirement) be transmitted to the network side preferentially to the BSR, so as to avoid the high-priority data being delayed due to the preferential transmission of the BSR.

[0207] Referring to FIG. 3, FIG. 3 is a flowchart of an information transmission method according to an embodiment of the present application. As shown in FIG. 3, the information transmission method comprises the following steps:

[0208] In step 201, the network side device sends first configuration information or second configuration information to the terminal.

[0209] The first configuration information is used for configuring the terminal to apply a first transmission priority rule or configuring the terminal not to apply the first transmission priority rule.

[0210] The second configuration information is used for configuring the terminal to apply the first transmission priority rule to transmission of a target LCH or configuring the terminal not to apply the first transmission priority rule to transmission of the target LCH.

[0211] The first transmission priority rule includes:

[0212] In a case where resources of the uplink grant are insufficient to carry all the to-be-transmitted data of the terminal and the resources of the uplink grant can carry all the to-be-transmitted data of a first LCH, a transmission priority of the to-be-transmitted data of the first LCH is higher than a transmission priority of triggered BSR MAC CE.

[0213] The to-be-transmitted data of the terminal includes to-be-transmitted data of at least two LCHs, the first LCH is an LCH with a highest logical channel priority in the at least two LCHs, and the target LCH is an LCH in the at least two LCHs.

[0214] It should be noted that the embodiment is an implementation of a network side device corresponding to the embodiment shown in FIG. 2, and the specific implementation can be referred to the related description of the embodiment shown in FIG. 2. To avoid repeated description, the embodiment will not be described herein.

[0215] The information transmission method provided in the embodiment can be executed by an information transmission device. In the embodiment, the information transmission method is executed by the information transmission device, and the information transmission device is described.

[0216] Referring to FIG. 4, FIG. 4 is a structure diagram of an information transmission device provided in the embodiment, and the terminal includes the information transmission device. As shown in FIG. 4, the information transmission device 300 includes:

[0217] The transmission module 301 is configured to perform transmission on resources of an uplink grant according to a first transmission priority rule.

[0218] The first transmission priority rule includes:

[0219] In a case where resources of the uplink grant are insufficient to carry all the to-be-transmitted data of the terminal and the resources of the uplink grant can carry all the to-be-transmitted data of a first LCH, a transmission priority of the to-be-transmitted data of the first LCH is higher than a transmission priority of triggered BSR MAC CE.

[0220] The data to be transmitted of the terminal includes data to be transmitted of at least two LCHs, and the first LCH is an LCH with the highest logical channel priority among the at least two LCHs.

[0221] Optionally, the transmission module is specifically configured to:

[0222] In a case where the resource of the uplink grant is insufficient to carry all the data to be transmitted of the terminal, and the resource of the uplink grant can carry all the data to be transmitted of a first logical channel (LCH), the data to be transmitted of the first LCH is transmitted on the resource of the uplink grant.

[0223] Optionally, the transmission module is specifically configured to:

[0224] In a case where the resource of the uplink grant is insufficient to carry all the data to be transmitted of the terminal, and the resource of the uplink grant can carry all the data to be transmitted of a first logical channel (LCH), the data to be transmitted of the first LCH is transmitted on the resource of the uplink grant.

[0225] If the resource of the uplink grant is insufficient to carry all the data to be transmitted of the first LCH and the BSR MAC CE and the MAC subheader thereof, the data to be transmitted of the first LCH is transmitted on the resource of the uplink grant, and the terminal does not transmit the BSR MAC CE and the MAC subheader thereof.

[0226] Optionally, the transmission module is specifically configured to:
