Abstract: A method and related apparatuses for Contention Based (CB) uplink transmission are provided by the present invention. And the method includes: configuring CB user group numbers and configuring a same CB Radio Network Temporary Identifier (CB-RNTI) for multiple CB user groups; for the multiple CB user groups having the same CB-RNTI, configuring a same CB Grant. With the present invention, it is not necessary to send a CB Grant for every CB user group, so that the resource overhead for CB Grant transmission is reduced, and thus the occurring probability of scheduling blocking is reduced.

Abstract: A method, an apparatus and a system for selecting a downlink primary carrier for transmitting data are disclosed. The method includes the following steps: A terminal obtains primary carrier selection information configured by a network; and the terminal determines a downlink carrier corresponding to an uplink carrier of the terminal as a downlink primary carrier for transmitting data according to the primary carrier selection information. In the embodiments of the present invention, the network selects a downlink carrier corresponding to an uplink carrier of the terminal as a downlink primary carrier for transmitting data. The terminal needs to detect only the downlink primary carrier, and the downlink carrier needs to be switched or detected only if the primary carrier receives a signaling message for detecting or receiving other carriers, so it is not necessary to switch or detect the downlink carrier frequently, which reduces battery consumption of the terminal.
Abstract translation: 公开了一种用于选择用于发送数据的下行链路主载波的方法，装置和系统。 该方法包括以下步骤：终端获取由网络配置的主载波选择信息; 并且终端根据主载波选择信息确定与终端的上行链路载波对应的下行链路载波作为用于发送数据的下行链路主载波。 在本发明的实施例中，网络选择与终端的上行链路载波对应的下行链路载波作为用于发送数据的下行主载波。 终端只需要检测下行主载波，只有当主载波接收到用于检测或接收其他载波的信令消息时，才需要切换或检测下行链路载波，所以不需要频繁地切换或检测下行链路载波 ，这降低了终端的电池消耗。

Abstract: Example communication methods and apparatus are described. In one example method, a terminal device receives configuration information of a first control resource set, where the configuration information of the first control resource set comprises mapping manner information of the first control resource set. The terminal device determines, based on the mapping manner information, a mapping manner between a control channel element (CCE) and resource element groups (REGs) in the first control resource set, where a REG in the first control resource set occupies one symbol in time domain and one resource block (RB) in frequency domain, and REGs in the first control resource set are numbered in a time-first manner. The mapping manner information indicates that the mapping manner is interleaved mapping.

Abstract: The present disclosure relates to the mobile communications field, and in particular, to a transmission resource determining technology in a wireless communications system. In a data transmission method, a network device determines a transmission resource used for data transmission, and performs data transmission with a terminal device on the determined transmission resource. A time domain resource occupied by the transmission resource in a time domain is one of N types of time domain resources, and a time length of any type of time domain resource in the N types of time domain resources is less than 1 ms. According to this method, a data transmission latency can be effectively reduced, thereby meeting a requirement for a low-latency service.

Abstract: A downlink control information (DCI) sending method and an apparatus are provided. A base station determines a first channel resource, where the first channel resource is located in the ith time unit of a subframe in a time domain, the subframe includes NT time units, NT is an integer greater than or equal to 2, and i is a positive integer less than or equal to NT; and the base station sends DCI to a terminal device on the first channel resource. In this solution, the first channel resource that carries the DCI is located in the ith time unit of the subframe in the time domain, where i is a positive integer less than or equal to NT. That is, there is a first channel resource in each time unit of the subframe.

Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.
