Resource allocation indication method, base station and terminal

Abstract

The invention discloses a resource allocation indication method, a base station and a terminal. The method comprises the following steps of allocating corresponding target transmission resources to the terminal when a target service occurs; and sending resource indication information to the terminal according to the target transmission resources, wherein the target transmission resources include uplink transmission resources or downlink transmission resources, the resource indication information includes first indication information and second indication information, the first indication information is used for indicating bandwidth parts of the target transmission resources, the bandwidth parts are part or all of the total bandwidth, and the second indication information is used for indicating position information of physical resource blocks (PRBs) allocated to the terminal in the PRBs corresponding to the bandwidth parts. In this way, the base station flexibly allocates the transmission resources for the target service based on the terminal capability, and sends the resource indication information to the terminal, so that the terminal can obtain frequency domain resources corresponding to the target transmission resources, and utilize the resources to transmit the target service, and thus the flexibility of frequency domain resource allocation and the system frequency utilization rate are improved.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a method for indicating resource allocation, a base station and a terminal. Background technique

[0002] Compared with traditional mobile communication systems, future New Radio (NR) mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of NR include mobile broadband enhanced eMBB, large-scale Internet of Things mMTC, and ultra-high reliability and ultra-low latency communication URLLC. These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. In order to meet different needs of services and different application scenarios, the subcarrier spacing of the NR system no longer adopts a single 15kHz like the traditional LTE system, but can support multiple subcarrier spacings, and different subcarrier spacings can be applied to different...

[0044] In this embodiment, the resource allocation indication method at the base station side of the present invention will be briefly introduced and explained in conjunction with the accompanying drawings.

[0045] Such as figure 2 As shown, the embodiment of the present invention provides a resource allocation indication method, which is applied to the base station side, and specifically includes the following steps:

[0046] Step 21: When a target service occurs, allocate corresponding target transmission resources to the terminal.

[0047] Here, the target service includes uplink service or downlink service. When a target service occurs, it means that the base station needs to send the target service to the terminal, or the terminal needs to send the target service to the base station. Correspondingly, the target transmission resources include uplink transmission resources or downlink transmission resources. Specifically, when the base station needs to send a target ser...
