The base station allocates a logical channel group (LCG) to which the logical channel (LCH) belongs, and one LCG may include one or more LCHs. The terminal may request an uplink transmission resource by sending a Buffer Status Report (BSR) to the base station, where the buffered data amount may be reported in units of LCG.

The new BSR is triggered only if the data of the LCH is reached and the priority is higher than any LCH included in the LCG of the current BSR. Otherwise, the BSR (regular BSR) will not be triggered. In this way, if different BSRs are used to request uplink transmission resources corresponding to different numerology or physical transmission parameter values, the received UL Grant may be used only for allocating uplink transmission resources requested by some BSRs, and the uplink transmission resources correspond to some Specific numerology or physical transfer parameter values.

可选地,如果收到针对某个numerology的UL grant,则可以停止或重启该numerology对应的BSR重传定时器。此时,可选地,如果有需要,终端设备可以再次触发或发送关联该numerology的BSR。Optionally, if the UL grant for a certain numerology is received, the BSR retransmission timer corresponding to the numerology may be stopped or restarted. At this time, optionally, the terminal device may trigger or send the BSR associated with the numerology again if necessary.
可选地,无论某个numerology对应的BSR重传定时器是否超时,终端设备都可以触发或发送关联另一个numerology的BSR。Optionally, the terminal device may trigger or send a BSR associated with another numerology regardless of whether the BSR retransmission timer corresponding to a numerology expires.
可选地,若在该第一numerology对应的BSR重传定时器超时时,该终端设备未从该网络设备收到用于分配对应于该第一numerology的上行传输资源的UL Grant,即未收到针对该第一numerology的UL Grant,则该终端设备可以重传该第一BSR或者重传该第一numerology对应的缓存数据量,并且可以重启该第一numerology对应的BSR重传定时器。Optionally, if the BSR retransmission timer corresponding to the first numerology expires, the terminal device does not receive the UL Grant for allocating the uplink transmission resource corresponding to the first numerology from the network device, that is, the unreceived To the UL Grant for the first numerology, the terminal device may retransmit the first BSR or retransmit the buffer data corresponding to the first numerology, and may restart the BSR retransmission timer corresponding to the first numerology.
可选地,在该第一numerology对应的BSR重传定时器未超时时,如果有属于某个LCH的数据到达并且需要请求对应于第二numerology的上行传输资源,无论是否收到针对该第一numerology的UL Grant,都可以触发新的BSR。此时,可选地,该终端设备可以向该网络设备发送第二BSR,该第二BSR请求对应于第二numerology的上行传输资源,即第二BSR关联第二numerology,但本申请不限于此。Optionally, when the BSR retransmission timer corresponding to the first numerology does not time out, if data belonging to a certain LCH arrives and an uplink transmission resource corresponding to the second numerology needs to be requested, whether or not the first transmission is received The UL Grant of numerology can trigger a new BSR.

可选地,也可以直接设置LCH所属的LCG,例如网络设备预先配置或者预先定义。此时,LCG的numerology属性可以依赖于其上报的LCH的numerology。可选地,当该LCG的BSR上报多个LCH的待发送数据量时,即该LCG对应的Buffer Size为多个LCH的待发送数据量之和,则该LCG的numerology属性可以依赖于其上报的LCH中具有最高优先级的LCH的numerology。例如,BSR中与LCG 1对应的Buffer Size包含LCH 1和LCH 2的待发送数据量,如表5所示的例子,第三列的数值越小,对应的优先级越高, 则LCH 1的优先级高于LCH 2的优先级。LCG 1对应的TTI长度可以等于LCH的maximum TTI duration,即4ms,但本申请不限于此。Optionally, the LCG to which the LCH belongs may also be directly set, for example, the network device is pre-configured or pre-defined. At this point, the numerology attribute of the LCG can depend on the numerology of the LCH it reports. Optionally, when the BSR of the LCG reports the amount of data to be sent of the multiple LCHs, that is, the Buffer Size corresponding to the LCG is the sum of the data volumes of the multiple LCHs to be sent, the numerology attribute of the LCG may depend on the report. The numerology of the LCH with the highest priority in the LCH. For example, the Buffer Size corresponding to the LCG 1 in the BSR includes the amount of data to be sent of LCH 1 and LCH 2, as shown in the example in Table 5. The smaller the value of the third column, the higher the corresponding priority, the LCH 1 The priority is higher than the priority of LCH 2. The TTI length corresponding to LCG 1 may be equal to the maximum TTI duration of the LCH, that is, 4 ms, but the application is not limited thereto.

Optionally, the terminal device may randomly select the transmitted BSR. Alternatively, the terminal device may select a priority according to the LCH included in the LCG corresponding to the multiple BSRs. For example, the terminal device may select a BSR of the LCG corresponding to the high priority LCH to transmit. Optionally, if the multiple BSRs are long-form BSRs, and there is an intersection between the numerology attributes of the multiple BSRs, the LCH with the highest priority among the LCHs reported by the same numerology may be selected from the multiple BSRs. The corresponding BSR is sent. As shown in Table 6 and Table 7, both BSR 1 and BSR 2 contain the Buffer Size of LCG 3, assuming that the Buffer Size of LCG 3 in BSR 1 is the amount of data to be transmitted of LCH 3, and the amount of LCG 3 in BSR 2 The Buffer Size is the amount of data to be sent of the LCH 1. According to Table 5, the priority of the LCH 1 is higher than the priority of the LCH 3. The terminal device can select the BSR 2 to transmit, but the application is not limited thereto.

可选地,BSR关联的numerology属性可以根据该BSR包括的LCG所对应的numerology属性要求来确定。Optionally, the numerology attribute of the BSR association may be determined according to a numerology attribute requirement corresponding to the LCG included in the BSR.
可选地,与该BSR匹配的上行传输资源可以是对应的numerology与该LCG的numerology属性匹配的上行传输资源。Optionally, the uplink transmission resource that matches the BSR may be an uplink transmission resource whose corresponding numerology matches the numerology attribute of the LCG.
作为一个可选例子,终端设备可以将最低限度地满足该LCG对应的numerology属性要求的上行传输资源确定为与该BSR匹配的上行传输资源。As an optional example, the terminal device may determine, as the uplink transmission resource that matches the requirement of the numerology attribute corresponding to the LCG, the uplink transmission resource that matches the BSR.
LCG的numerology属性要求可以用于确定与BSR匹配的上行传输资源。可选地,LCG对应的numerology属性要求可以具体为上述实施例中的LCG对应的numerology属性。或者,也可以依赖于该BSR中包含的该LCG的Buffer Size对应的LCH的numerology属性要求,例如,若该BSR包含属于该LCG的至少一个LCH的待发送数据量,该终端设备可以将该至少一个LCH中具有最高优先级的LCH的numerology属性要求确定为该LCG的numerology属性要求,但本申请不限于此。或者,LCG对应的numerology属性要求也可以是额外定义的参数,具体可以由网络设备预先配置或者预先定义,例如终端设备可以接收网络设备发送的第四指示信息,该第四指示信息可以用于指示该LCG对应的numerology属性要求,本申请不限于此。The LCG's numerology attribute requirement can be used to determine the uplink transmission resources that match the BSR. Optionally, the numerology attribute requirement corresponding to the LCG may be specifically the numerology attribute corresponding to the LCG in the foregoing embodiment. Alternatively, the terminal device may also depend on the numerology attribute requirement of the LCH corresponding to the Buffer Size of the LCG included in the BSR. For example, if the BSR includes the amount of data to be sent of the at least one LCH belonging to the LCG, the terminal device may The numerology attribute of the LCH having the highest priority in one LCH is determined to be the numerology attribute requirement of the LCG, but the application is not limited thereto. Alternatively, the numerology attribute requirement corresponding to the LCG may also be an additional defined parameter, which may be pre-configured or pre-defined by the network device. For example, the terminal device may receive the fourth indication information sent by the network device, and the fourth indication information may be used to indicate The numerology attribute corresponding to the LCG is required to be, and the application is not limited thereto.
作为一个可选例子,LCG对应的numerology属性要求可以具体为物理传输参数的值等于某个选择门限,即LCG对应的numerology属性要求可以具体为上文所述的LCG对应的numerology属性。此时,可以将对应的numerology属性与LCG对应的numerology属性相同的上行传输资源确定为与BSR匹配的上行传输资源,作为一个可选例子,可以将对应的第一物理传输参数(例如TTI长度)的值等于LCG对应的第一物理传输参数的 值的上行传输资源确定为LCG的BSR匹配的上行传输资源。例如,终端设备当前可用的上行传输资源如表8所示,其中UL Grant 1分配的上行传输资源对应的TTI长度为4ms,UL Grant 2分配的上行传输资源对应的TTI长度为2ms。LCG对应的TTI长度如表9所示,通过比较表8和表9的前两列,可以确定LCG 1的BSR匹配的上行传输资源为UL Grant1分配的上行传输资源,由于当前可用的上行传输资源中不存在TTI长度等于1的传输资源,LCG 2的BSR无匹配的上行传输资源,LCG 3的BSR匹配的上行传输资源为UL Grant2分配的上行传输资源,但本申请不限于此。As an example, the value of the numerology attribute of the LCG may be specifically that the value of the physical transmission parameter is equal to a certain selection threshold, that is, the numerology attribute of the LCG may be specifically the numerology attribute corresponding to the LCG described above. In this case, the uplink transmission resource with the same numerology attribute and the same numerology attribute as the LCG may be determined as the uplink transmission resource that matches the BSR. As an optional example, the corresponding first physical transmission parameter (for example, TTI length) may be used. The uplink transmission resource whose value is equal to the value of the first physical transmission parameter corresponding to the LCG is determined to be the uplink transmission resource matched by the BSR of the LCG. For example, the uplink transmission resources currently available to the terminal device are as shown in Table 8. The length of the TTI corresponding to the uplink transmission resource allocated by the UL Grant 1 is 4 ms, and the length of the TTI corresponding to the uplink transmission resource allocated by the UL Grant 2 is 2 ms. The length of the TTI corresponding to the LCG is as shown in Table 9. By comparing the first two columns of Table 8 and Table 9, it can be determined that the uplink transmission resource of the BSR matching of the LCG 1 is the uplink transmission resource allocated by the UL Grant1, because the currently available uplink transmission resource There is no transmission resource with a TTI length equal to 1. The BSR of the LCG 2 has no matching uplink transmission resources, and the uplink transmission resource matched by the BSR of the LCG 3 is an uplink transmission resource allocated by the UL Grant 2. However, the present application is not limited thereto.

作为另一个可选例子,可以将最低限度地满足LCG对应的numerology属性要求的上行传输资源确定为该LCG的BSR匹配的上行传输资源。LCG对应的numerology属性要求可以包括:小于或等于LCG对应的最大TTI长度,或者大于或等于LCG对应的最小SCS,最低限度地满足的含义可以参见上文实施例的描述,为了简洁,这里不再赘述。例如,LCG对应的numerology属性要求可以如表10所示,此时,由于当前可用的上行传输资源中不存在对应的TTI长度小于或等于1的传输资源,LCG 2的BSR无可用资源。As another optional example, the uplink transmission resource that meets the minimum requirement of the numerology attribute corresponding to the LCG may be determined as the uplink transmission resource of the BSR matching of the LCG. The numerology attribute requirement corresponding to the LCG may include: less than or equal to the maximum TTI length corresponding to the LCG, or greater than or equal to the minimum SCS corresponding to the LCG. The meaning of the minimum satisfaction may be referred to the description of the above embodiment. Narration. For example, the numerology attribute requirement of the LCG can be as shown in Table 10. In this case, since there is no corresponding transmission resource with a TTI length less than or equal to 1 in the currently available uplink transmission resource, the BSR of the LCG 2 has no available resources.
表10 LCG对应的numerology属性要求以及选择的上行传输资源Table 10 numerology attribute requirements corresponding to the LCG and selected uplink transmission resources
可选地,若根据numerology属性找不到与BSR匹配的可用上行传输资源,可以不发送该BSR,这样可能会引入传输时延。作为另一个可选实施例,在本申请中,可以不约束BSR传输时使用的上行传输资源的numerology属性,即BSR可在任意numerology属性的上行传输资源传输,此时,BSR匹配的上行传输资源的选择可以不依赖于上行传输资源的 numerology属性,例如,BSR匹配的上行传输资源是可以任意选择的。例如,虽然LCG对应TTI duration为2ms,但当UL grant分配的是具有1ms的TTI duration的资源时,该LCG的BSR可以在该资源上发送,但本发明实施例不限于此。Optionally, if the available uplink transmission resource that matches the BSR cannot be found according to the numerology attribute, the BSR may not be sent, which may introduce a transmission delay. As another optional embodiment, in this application, the numerology attribute of the uplink transmission resource used in the BSR transmission may not be constrained, that is, the BSR may transmit the uplink transmission resource in any numerology attribute. In this case, the BSR matches the uplink transmission resource. The selection may not depend on the numerology attribute of the uplink transmission resource. For example, the uplink transmission resource matched by the BSR may be arbitrarily selected. For example, although the LTG corresponding to the TTI duration is 2 ms, when the UL grant allocates a resource having a TTI duration of 1 ms, the BSR of the LCG may be sent on the resource, but the embodiment of the present invention is not limited thereto.
S620,终端设备在该匹配的上行传输资源上发送该BSR。S620. The terminal device sends the BSR on the matched uplink transmission resource.
S630,网络设备接收该BSR,并可选地为终端设备分配上行传输资源。S630. The network device receives the BSR, and optionally allocates an uplink transmission resource to the terminal device.
可选地,该网络设备可以根据该BSR占用的上行传输资源对应的numerology属性,为终端设备分配上行传输资源。例如,该网络设备可以分配对应的numerology与该BSR占用的而上行传输资源相同的资源。此时,可选地,该BSR可以不包含Buffer Size对应的LCG的信息。Optionally, the network device may allocate an uplink transmission resource to the terminal device according to the numerology attribute corresponding to the uplink transmission resource occupied by the BSR. For example, the network device may allocate a resource whose corresponding numerology is the same as the uplink transmission resource occupied by the BSR. In this case, optionally, the BSR may not include information about the LCG corresponding to the Buffer Size.
可选地,该BSR可以确定该BSR中包含的Buffer Size对应的LCG,并根据该LCG对应的numerology属性要求或者该LCG对应的numerology属性,为终端设备分配上行传输资源,本申请对此不做限定。Optionally, the BSR may determine an LCG corresponding to the Buffer Size included in the BSR, and allocate an uplink transmission resource to the terminal device according to the numerology attribute requirement of the LCG or the numerology attribute corresponding to the LCG, and the application does not do this. limited.
因此,本申请提供的用于传输缓存状态报告的方法,通过确定与BSR匹配的上行传输资源,并在与该BSR匹配的上行传输资源上传输该BSR,有利于提高***性能。Therefore, the method for transmitting a buffer status report provided by the present application is beneficial to improving system performance by determining an uplink transmission resource that matches a BSR and transmitting the BSR on an uplink transmission resource that matches the BSR.
本申请还提供了一种传输调度请求(Scheduling Request,SR)的方法。在该方法中,如果终端设备发送了BSR,发现用于传输SR的可用资源,并且SR能够先于BSR被接收,则终端设备可以发送SR,以使得网络设备尽早地收到终端设备的请求,有利于网络设备更早地进行资源调度并且终端设备更早地进行数据传输。The application also provides a method for transmitting a scheduling request (SR). In the method, if the terminal device sends the BSR and finds available resources for transmitting the SR, and the SR can be received before the BSR, the terminal device can send the SR, so that the network device receives the request of the terminal device as soon as possible. It is advantageous for the network device to perform resource scheduling earlier and the terminal device to perform data transmission earlier.
具体地,终端设备可以向网络设备发送BSR,若该BSR对应的BSR重传定时器未超时,并且终端设备发现用于传输SR的可用的上行传输资源,其中,该可用的上行传输资源的结束时刻早于该BSR占用的上行传输资源的结束时刻,则该终端设备可以在该可用的上行传输资源上向该网络设备发送SR。相应地,网络设备可以接收终端设备发送的SR,并根据该SR,为终端设备分配传输资源。Specifically, the terminal device may send a BSR to the network device, if the BSR retransmission timer corresponding to the BSR does not time out, and the terminal device finds an available uplink transmission resource for transmitting the SR, where the available uplink transmission resource ends. When the time is earlier than the end time of the uplink transmission resource occupied by the BSR, the terminal device may send the SR to the network device on the available uplink transmission resource. Correspondingly, the network device can receive the SR sent by the terminal device, and allocate a transmission resource to the terminal device according to the SR.
作为一个例子,如图14所示,numerology 1对应的slot长度为0.5ms,numerology 2对应的slot长度为0.125ms。在t0时刻,终端设备在对应于numerology 1的上行传输资源上发送了BSR,根据numerology 1对应的slot长度,该BSR可以于t0+0.5ms被网络设备接收完毕。在发送该BSR之后,终端设备发现了可用于传输SR的对应于numerology的上行传输资源,该上行传输资源的起始时刻为t0+0.125ms。如果该终端设备在t0+0.125ms发送SR,根据numerology 2对应的slot长度,该SR可以在t0+0.25ms被网络设备接收完毕,即该SR可以先于该BSR被网络设备接收到。此时,该终端设备可以在t0+0.125ms向网络设备发送SR,但本发明实施例不限于此。As an example, as shown in FIG. 14, the slot length corresponding to numerology 1 is 0.5 ms, and the slot length corresponding to numerology 2 is 0.125 ms. At time t0, the terminal device sends a BSR on the uplink transmission resource corresponding to the numerology 1. According to the slot length corresponding to the numerology 1, the BSR can be received by the network device at t0+0.5 ms. After transmitting the BSR, the terminal device discovers an uplink transmission resource corresponding to the numerology that can be used to transmit the SR, and the starting time of the uplink transmission resource is t0+0.125 ms. If the terminal device sends the SR at t0+0.125ms, according to the slot length corresponding to the numerology 2, the SR can be received by the network device at t0+0.25ms, that is, the SR can be received by the network device before the BSR. At this time, the terminal device may send the SR to the network device at t0+0.125 ms, but the embodiment of the present invention is not limited thereto.
在本申请中,在收到SR后,网络设备可能会收到关联同一numerology的BSR,此时,可选地,如果该SR和BSR之间的时间间隔小于某个预设时间段,则该网络设备可以舍弃该BSR,不对该BSR进行响应。这样,该网络设备可以在该预设时间段内仅响应终端设备发送的针对同一numerology的一次资源分配请求。可选地,该预设时间段可以为该numerology对应的BSR重传定时器的时长,或者也可以为SR发送周期,本申请对此不做限定。In this application, after receiving the SR, the network device may receive the BSR associated with the same numerology. In this case, if the time interval between the SR and the BSR is less than a preset time period, The network device can discard the BSR and not respond to the BSR. In this way, the network device can respond to only one resource allocation request for the same numerology sent by the terminal device within the preset time period. Optionally, the preset time period may be the duration of the BSR retransmission timer corresponding to the numerology, or may also be an SR sending period, which is not limited in this application.
