摘要： A multiple-input multiple output (MIMO) downlink (DL) data stream control apparatus configured to determine a subset of first and second support angles or support angle pairs for use in downlink transmission from antenna elements of MIMO antenna arrays. The subsets of support angles are determined from one or more uplink signals (UL) received at antenna elements of the MIMO antenna arrays. The elements of the MIMO arrays are arranged in rows and columns being angled to each other. The control apparatus transforms signals received by row and column elements from spatial domain to first and second support signals, respectively, in angular domain. Each support signal is a function of a corresponding support angle, and the magnitude of the support signals is a function of the angle of arrival of the UL signals. Based on magnitudes of the support signals, the control apparatus determines subsets of pairs of support angles.

摘要： The present solution relates to method in a first communication node (105) for enabling use of a subset of code words in a communication network (200). The first communication node (105) comprises a transmission circuit (501) and a receiving circuit (502). Data is transmitted from the transmission circuit to the second communication node (103). The data is sent using a transmission mode. A subset of code words is selected from at least one codebook. The subset of code words is based on the transmission mode. Information of the used transmission mode is provided to the receiving circuit (502). The information enables the receiving circuit (502) to detect a message from the second communication node (103) using the subset of code words. The message from the second communication node (103) is detected in the receiving circuit (502), using the subset of code words.
