Problems solved by technology

However, with the improvement of the performance of narrowband terminals, the narrowband bandwidth that can be supported is increasing, so the number of PRBs supported is also increasing, that is to say, the number of bits required for the PRB resource allocation indication field is also increasing , which consumes more resources for DCI

Abstract

The present disclosure relates to a resource allocation indication method and apparatus, a base station, and a terminal. The method is applied to a base station based on a machine type communication MTC, including: limiting an allocation amount and / or an allocation position of a physical resource block PRB in a narrowband allocated by a base station to a terminal; determining the number of bits occupied by the downlink control information DCI of a PRB resource allocation indication field according to the allocated amount and / or the allocated location; and based on the number of bits, establishing a mapping relationship between the PRB resource allocation indication field and the allocation amount and the allocation location of the PRB in the narrowband. With the embodiment method adopted by the present disclosure, the space occupied by the PRB resource allocation indication field in the downlink control information DCI can be compressed.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for indicating resource allocation, a base station, and a terminal. Background technique [0002] In wireless communication systems such as Long Term Evolution (LTE) systems and Long Term Evolution Advanced (LTE-A) systems, support Machine Type Communications (MTC) applications with a large number of terminals , in order to reduce the cost of the MTC terminal, it may be stipulated that the MTC terminal can only perform signaling or data processing in the narrowband (that is, a subband in the system broadband), so the MTC terminal can be called a narrowband terminal. [0003] In related technologies, the base station may send resource indication information (such as downlink control information DCI) to the narrowband terminal through a control channel, so as to schedule the narrowband terminal to perform data transmission within the curre...
