Title
(EN) METHOD FOR TRANSMITTING MESSAGE DURING RANDOM ACCESS, AND RELATED DEVICE
(ZH) 随机接入过程中消息传输的方法及相关装置
Abstract
(EN) Provided in the present application are a method for transmitting a message during random access, and a related device. The method comprises: receiving a broadcast system message from a network device, and determining, according to the system message, a maximum transmission block size (TBS) allowed to be used; receiving downlink control information from the network device, wherein the downlink control information comprises a first number of repetition times and a first TBS; determining a second number of repetition times that the scheduling transmission message for random access is re-sent, according to the first number of repetition times, the first TBS, a second TBS used in sending a scheduling transmission message for random access the first time, and the maximum TBS; and re-sending thescheduling transmission message for random access to the network device according to the second TBS and the second number of repetition times. By means of the embodiments of the present application,randomly accessible resources can be scheduled flexibly, avoiding collision between re-transmission of a scheduling transmission message for random access and uplink transmission of other users, and having strong adaptivity. The method and device provided in the embodiments of the present application increase network coverage capability and can be applied to an Internet of Things, for example, anMTC, an IoT, an LTE-M, an M2M, etc.
(ZH) 本申请实施例提供了一种随机接入过程中消息传输的方法及相关装置,其中方法包括:从网络设备接收广播的系统消息,根据该系统消息确定允许使用的最大传输块大小TBS;从网络设备接收下行控制信息,该下行控制信息中包括第一重复次数和第一TBS;根据该第一重复次数、该第一TBS、第一次发送随机接入的调度传输消息所使用的第二TBS和该最大TBS确定重新发送随机接入的调度传输消息的第二重复次数;按照该第二TBS和第二重复次数向网络设备重新发送随机接入的调度传输消息。采用本申请实施例,可随机接入资源的调度灵活性,避免随机接入的调度传输消息重传和其它用户的上行传输之间的冲突,适用性更强。本申请实施例提供的方法和设备提高了网络的覆盖能力,可以应用于物联网,例如MTC、IoT、LTE‑M、M2M等。
