Abstract
Embodiments of the present disclosure relate to channel state information measurement in communication networks. According to embodiments of the present disclosure, the measurement resource unit, MRU, configuration is determined based on the number of MRU and the identity of the cell. The MRU configuration is scalable and the set of MRUs is reused by the network. In this way, the resources are saved and the accuracy is improved.
Claims18
A device, comprising:
- at least one processor;
- and
- at least one memory including computer program codes;
- the at least one memory and the computer program codes are configured to, with the at least one processor, cause the device to:
- determine a set of measurement resource units, MRUs, shared by a group of cells, the device associated with a cell of the group of cells;
- determine MRU configuration for the group of cells based on the number of MRUs and the number of cells, such that
- one or more cells are assigned with the first number of MRUs for transmission,
- the one or more cells are assigned with the second number of MRUs for measurement, and
- the number of concurrent transmissions caused by any two distinct cells is no more than a threshold number;
- select, based on an identity of the cell and the MRU configuration, a first subset of MRUs from the set of MRUs for the device to perform transmissions;
- select, based on the identity of the cell and the MRU configuration, a second subset of MRUs from the set of MRUs for the device to perform measurements;
- and
- determine, based on the identity of the cell and the MRU configuration, a measurement matrix for the device to perform estimation.
