Abstract

The invention provides a method and a device for indicating orthogonal cover code (OCC) configuration and frequency hopping configuration. The method comprises the following steps that: a base station indicates the OCC configuration or the frequency hopping configuration to a terminal through a signaling, wherein the other one in the OCC configuration and the frequency hopping configuration is bound with the indicated configuration in a pre-determined mapping relationship; and the terminal performs OCC weighting and determines whether to perform group frequency hopping or series frequency hopping according to the received OCC configuration or the frequency hopping configuration. By the method and the device for the combined indication of the OCC configuration and the frequency hopping configuration, the OCC configuration and the frequency hopping configuration can be indicated simultaneously, so that the utilization flexibility of the OCC is improved, and the signaling overhead is reduced by a binding relationship between the OCC configuration and the frequency hopping configuration.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and a device for indicating orthogonal cover code configuration and frequency hopping configuration. Background technique [0002] In LTE-A, uplink multi-antenna transmission is introduced, and the terminal can use multiple radio frequency channels to send data to achieve higher spectrum efficiency. In order to ensure the performance of single-user multi-layer transmission and multi-user transmission, and reduce inter-layer and inter-user interference, OCC (Orthogonal Cover Code, Orthogonal Cover Code) can be introduced to ensure the orthogonality between layers or users. However, OCC can only be used in a non-slot frequency hopping system. If the cell enables group frequency hopping or sequence frequency hopping, OCC cannot be used. In order to enable users in this type of cell to use OCC, the group frequency hopping and sequence frequency hopping of each user can be ...
