Abstract: The communication method and the communications apparatus may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: A first terminal apparatus determines a scaling factor based on a subcarrier spacing of a first time-frequency resource to be used to send first data and/or a quantity of slots occupied by the first time-frequency resource. The first data is to-be-sent data of the first terminal apparatus, and the first time-frequency resource occupies a single slot or a plurality of consecutive slots. Then, the first terminal apparatus determines, based on the scaling factor, a size of a transmission block carrying the first data, and sends the transmission block carrying the first data to a second terminal apparatus on the first time-frequency resource.

Abstract: The present invention provides a method and a terminal for adjusting a hybrid automatic repeat request HARQ buffer size, and relates to the field of communications technologies. A rated HARQ buffer size of a code block is reduced according to a rated proportion; then it is determined whether the reduced HARQ buffer size falls in a preset threshold range; and if the reduced HARQ buffer size falls in the preset threshold range, only partial coded data is stored. In this way, it is ensured, by setting a rated proportion, that decoding performance of the reduced coded data does not degrade greatly, and further, setting a threshold range helps to limit conditions under which the HARQ buffer size can be reduced. Consequently, technical solutions provided by embodiments of the present invention can reduce the required HARQ buffer size while ensuring decoding performance.
Abstract translation: 本发明提供了一种用于调整混合自动重传请求HARQ缓冲器大小的方法和终端，并且涉及通信技术领域。 根据额定比例减少代码块的额定HARQ缓冲区大小; 则确定缩减的HARQ缓冲器大小是否落在预设的阈值范围内; 并且如果减少的HARQ缓冲器大小落在预设的阈值范围内，则仅存储部分编码数据。 以这种方式，通过设定额定比例来确保降低的编码数据的解码性能不会大大降低，并且进一步地，设置阈值范围有助于限制可以减少HARQ缓冲器大小的条件。 因此，本发明的实施例提供的技术方案可以在确保解码性能的同时减少所需的HARQ缓冲器大小。

Abstract: This application relates to a communication method and apparatus, and may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V, or may be used in fields such as intelligent driving and intelligent connected vehicles. A first resource is determined in a first resource set, and a jth synchronization signal block in N synchronization signal blocks is sent on a jth candidate resource in N candidate resources. The first resource set includes M groups, and an ith group in the M groups includes X candidate resources. M×X candidate resources included in the first resource set may be used to transmit a synchronization signal block. Each of the N synchronization signal blocks occupies Y symbols in time domain, where Y is an integer greater than or equal to 5. The first resource includes the N candidate resources, and the N candidate resources belong to one or more groups in the M groups.
