Description
本发明涉及无线通信***中的无线信号的传输方案,特别是涉及基于蜂窝网通信的上行传输的方法和装置。The present invention relates to a transmission scheme for wireless signals in a wireless communication system, and more particularly to a method and apparatus for uplink transmission based on cellular network communication.
传统的基于数字调制方式的无线通信***,例如3GPP(3rd Generation Partner Project,第三代合作伙伴项目)蜂窝***中,上行无线信号的发送是基于基站的调度。而对下一代无线通信***而言,IoT(Internet of Things,物联网)通信可能会成为一个重要的应用场景。In a conventional digital modulation-based wireless communication system, such as a 3GPP (3rd Generation Partner Project) cellular system, uplink wireless signal transmission is based on base station scheduling. For the next generation of wireless communication systems, IoT (Internet of Things) communication may become an important application scenario.
IoT通信的特征包括:终端设备的数量非常巨大,终端设备所支持的待机时间较长(功耗要低),终端设备的成本较低等方面。传统的基于调度的上行发送不再适用于IoT,原因包括:The characteristics of IoT communication include: the number of terminal devices is very large, the standby time supported by the terminal device is long (low power consumption), and the cost of the terminal device is low. Traditional scheduling-based uplink transmission is no longer applicable to IoT, for the following reasons:
-.下行调度所需要的信令会严重降低传输效率。尤其考虑到典型的一次IoT的上行发送所包括的信息比特数量通常比较少。- The signaling required for downlink scheduling can severely reduce transmission efficiency. In particular, it is considered that the number of information bits included in the uplink transmission of a typical primary IoT is usually small.
-.增加终端设备的功耗,降低待机时间。现有的***中,终端设备首先通过例如SR(Scheduling Request,调度请求)等信令,然后才能发送上行传输。- Increase the power consumption of the terminal device and reduce the standby time. In the existing system, the terminal device first transmits signaling such as an SR (Scheduling Request) before transmitting the uplink transmission.
-.增大了上行传输延时。一些特殊场景中,IoT通信需要较低的传输延时,而现有的基于调度的上行传输不能满足这一需求。-. Increased uplink transmission delay. In some special scenarios, IoT communication requires a lower transmission delay, and existing scheduling-based uplink transmissions cannot meet this requirement.
针对上述问题,CB(Contention Based,基于内容的)上行传输被提出,即UE不需要基站的调度即可发送上行信息。如果没有发生(两个或者多个UE之间的)冲突,则基站能够正确译码上行信息。In response to the above problem, CB (Contention Based) uplink transmission is proposed, that is, the UE does not need the scheduling of the base station to transmit uplink information. If no collision occurs (between two or more UEs), the base station can correctly decode the uplink information.
发明内容Summary of the invention
发明人通过研究发现,基站需要为CB上行传输预留相应的时频资源。然而,由于基站不确定真实传输的上行信息所需的时频资源的尺寸,因此无法预留合适数量的时频资源。The inventors found through research that the base station needs to reserve corresponding time-frequency resources for CB uplink transmission. However, since the base station is not sure of the size of the time-frequency resource required for the real-transmitted uplink information, it is impossible to reserve an appropriate number of time-frequency resources.
进一步的,当两个或者多个UE(User Equipment,用户设备)发送
的上行信号发生冲突的时候,基站无法正确译码,降低了传输效率。尤其当UE的数量非常大的时候,冲突的概率显著增加。Further, when two or more UEs (User Equipments) send
When the uplink signals collide, the base station cannot decode correctly, which reduces the transmission efficiency. Especially when the number of UEs is very large, the probability of collisions increases significantly.
针对上述问题,本发明提供了解决方案。需要说明的是,在不冲突的情况下,本申请的实施例和实施例中的特征可以任意相互组合。例如,本申请的UE中的实施例和实施例中的特征可以应用到基站中,反之亦然。In response to the above problems, the present invention provides a solution. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily. For example, features in embodiments and embodiments in the UE of the present application may be applied to a base station, and vice versa.
本发明公开了一种用于无线通信的UE中方法,其中,包括如下步骤:The invention discloses a method in a UE for wireless communication, which comprises the following steps:
-步骤A.接收第一信令和第二信令。Step A. Receive the first signaling and the second signaling.
-步骤B.确定目标时频资源块,在目标时频资源块上发送第一无线信号。Step B. Determine the target time-frequency resource block and transmit the first wireless signal on the target time-frequency resource block.
其中,第一信令被用于确定所述第一资源池,第二信令被用于确定所述第二资源池。所述目标时频资源块属于所述第一资源池,或者所述目标时频资源块属于所述第二资源池。{所述第一信令,所述第二信令}中的所述第一信令是小区特定(Cell Specific)的。The first signaling is used to determine the first resource pool, and the second signaling is used to determine the second resource pool. The target time-frequency resource block belongs to the first resource pool, or the target time-frequency resource block belongs to the second resource pool. The first signaling in the {first signaling, the second signaling} is Cell Specific.
作为一个实施例,所述步骤B中,所述UE从{所述第一资源池,所述第二资源池}中选出所述目标时频资源块。As an embodiment, in the step B, the UE selects the target time-frequency resource block from the {first resource pool, the second resource pool}.
CB上行传输中,一个直观的解决方案是基站为终端预留资源池,终端自行在预留的时频池中选择合适的时频资源用于发送无线信号。而上述实施例中,所述UE能从两个资源池(而不是一个资源池)中选择合适的时频资源用于发送无线信号。In the CB uplink transmission, an intuitive solution is that the base station reserves a resource pool for the terminal, and the terminal selects an appropriate time-frequency resource in the reserved time-frequency pool for transmitting the wireless signal. In the above embodiment, the UE can select an appropriate time-frequency resource from two resource pools (rather than one resource pool) for transmitting a wireless signal.
作为一个实施例,所述资源池在时域上包括多个时间间隔,所述多个时间间隔中的任意两个时间间隔在时域上是不连续的。作为一个实施例,所述时间间隔的持续时间不超过1毫秒。As an embodiment, the resource pool includes a plurality of time intervals on the time domain, and any two of the plurality of time intervals are discontinuous in the time domain. As an embodiment, the duration of the time interval does not exceed 1 millisecond.
作为一个实施例,所述资源池在频域上包括多个子频带,所述多个子频带中的任意两个子频带在频域上是不连续的。In one embodiment, the resource pool includes a plurality of sub-bands in the frequency domain, and any two of the plurality of sub-bands are discontinuous in the frequency domain.
作为一个实施例,所述资源池在频域上是连续的。As an embodiment, the resource pool is contiguous in the frequency domain.
作为一个实施例,所述第一无线信号包括{上行信息,UCI(Uplink上Control Information,上行控制信息),RS(Reference Signal,参考信号)}中的至少之一。As an embodiment, the first wireless signal includes at least one of {uplink information, UCI (Control Information on Uplink), and RS (Reference Signal).
作为上述实施例的一个子实施例,所述上行信息在PUSCH(Physical Uplink Shared Channel,物理上行共享信道)上传输。As a sub-embodiment of the foregoing embodiment, the uplink information is transmitted on a PUSCH (Physical Uplink Shared Channel).
作为上述实施例的一个子实施例,所述上行信息对应的传输信道是
UL-SCH(UpLink Shared Channel,上行共享信道)。As a sub-embodiment of the foregoing embodiment, the transport channel corresponding to the uplink information is
UL-SCH (UpLink Shared Channel).
作为一个子实施例,所述上行信息对应一个TB(Transport Block,传输块)。As a sub-embodiment, the uplink information corresponds to one TB (Transport Block).
作为一个实施例,所述小区特定的是指:小区中的所有具备相应功能的终端都可能接收到。As an embodiment, the cell-specific means that all terminals in the cell with corresponding functions may receive.
作为一个实施例,所述所述第一信令是小区特定的是指:所述第一信令所占用的逻辑信道是BCCH(Broadcast Control Channel,广播控制信道)。As an embodiment, the first signaling is cell-specific, and the logical channel occupied by the first signaling is a BCCH (Broadcast Control Channel).
作为一个实施例,所述所述第一信令是小区特定的是指:所述第一信令所占用的传输信道是BCH(Broadcast Channel,广播信道)。As an embodiment, the first signaling is cell-specific, and the transmission channel occupied by the first signaling is a BCH (Broadcast Channel).
作为一个实施例,所述所述第一信令是小区特定的是指:所述第一信令被SIB(System Information Block,***信息块)携带。As an embodiment, the first signaling is cell-specific: the first signaling is carried by a SIB (System Information Block).

上述两个实施例中,所述第一资源池可能被小区内所有具备相应功能的终端占用,所述第二资源池仅可能被特定的一个或者多个终端所占用。即:所述第一资源池中的上行传输发生冲突的可能性较高,所述第一资源池中的上行传输发生冲突的可能性较低。然而,所述第一资源池的实时性可能较高,或者所占用的资源(相比为所有终端组所预留的资源池)较少。因此,所述第一资源池和所述第二资源池的结合能在性能和效率之间取得平衡。In the above two embodiments, the first resource pool may be occupied by all terminals in the cell with corresponding functions, and the second resource pool may only be occupied by a specific one or more terminals. That is, the uplink transmission in the first resource pool is highly likely to collide, and the uplink transmission in the first resource pool is less likely to collide. However, the real-time performance of the first resource pool may be higher, or the occupied resources (compared to the resource pool reserved for all terminal groups) are less. Therefore, the combination of the first resource pool and the second resource pool can strike a balance between performance and efficiency.
作为一个实施例,所述步骤B中,所述UE根据{Buffer状态,所述第一资源池中即将到来的第一个时频资源,所述第二资源池中即将到来的第一个时频资源}中的至少之一确定所述目标时频资源块。作为本实施例的一个子实施例,如果所述Buffer状态满足上行传输的触发条件,
