example 1

[0090] Example 1, when the system bandwidth is 100RB, the configurable values ​​of the first frequency domain resource unit size are 4, 6, 8, 10; when the system bandwidth is 200RB, the configurable values ​​of the first frequency domain resource unit size are 4, 8, 12 , 16. The configurable number of the size of the first frequency domain resource unit is 4, so that the base station can use 2-bit indication information to indicate the value of the currently used first frequency domain resource unit size.

example 2

[0091]Example 2, based on Example 1, when the system bandwidth is 100 RB, if the 2-bit indication information is 00, it means that the selected first frequency domain resource unit size is 4, and if the 2-bit indication information is 01, it means that the selected The size of the first frequency domain resource unit is 6; if the 2-bit indication information is 10, it indicates that the selected first frequency domain resource unit size is 8; if the 2-bit indication information is 11, it indicates that the selected first frequency domain The resource unit size is 10.

example 3

[0092] Example 3, based on Example 1, when the system bandwidth is 200RB, if the 2-bit indication information is 00, it means that the selected first frequency domain resource unit size is 4; if the 2-bit indication information is 01, it means that the selected The size of the first frequency domain resource unit is 8; if the 2-bit indication information is 10, the selected first frequency domain resource unit size is 12; if the 2-bit indication information is 11, it indicates the selected first frequency domain resource The cell size is 16.

[0093] RBG-related configuration information can be carried in at least one of the following: broadcast signaling, high-level signaling (Radio Resource Control (Radio Resource Control, RRC) signaling, etc.), media access control control element (Media Access Control Control Element, MAC CE) signaling, L1 control signaling (DCI, etc.), etc. For example, the high-level signaling includes master information block (Master Information block,...

Abstract

The application discloses a resource allocation method and equipment in a communication system. The method comprises the following steps: a terminal determines the first frequency domain resource unitsize according to configuration information; the configuration information comprises predefined first configuration information; or the configuration information comprises second configuration information sent to the terminal by the base station; or the configuration information comprises the first configuration information and the second configuration information; the terminal determines resource allocation related parameter according to the first frequency domain resource unit size; the terminal determines the first frequency domain resource unit size according to the predefined first configuration information, or determines the first frequency domain resource unit size according to the second configuration information indicated by the base station, or determines the first frequency domain resource unit size according to the second configuration information indicated by the base station and the first configuration information predefined by the terminal, thereby realizing the configurable size of the first frequency domain resource unit. Under the big bandwidth or new application demand scene, the resource allocation granularity flexible configuration can be realized so as to satisfy different service demands.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for resource allocation in a communication system. Background technique [0002] In the LTE-A system, the frequency-domain resource granularity of resources is resource block (resource block, RB). In order to avoid the excessive downlink control information (Downlink Control Information, DCI) overhead caused by the large number of RBs in the system when the bandwidth is large, The standard defines a resource block group (resource block group, RBG), and an RBG is composed of one or more continuous virtual resource blocks (virtual resource block, VRB). In the LTE-A system, in some transmission modes, resource allocation is related to the size of the RBG. Generally, the size of the RBG can be regarded as the basic granularity of resource scheduling. The maximum system bandwidth supported by the LTE-A system is 20MHZ, and under a fixed ...
