Abstract:
1. A method for determining a number of coded control information symbols in a spatial layer, in a communication system wherein a User Equipment (UE) is assigned by a base station transmission of a Physical Uplink Shared CHannel (PUSCH) from multiple transmitter antennas over a number of sub-carriers M sc PUSCH in a frequency domain and over a number of symbols in a time domain, the PUSCH being transmitted over multiple spatial layers and including two Codewords (CWs), CW 0 and CW 1 , each conveying a corresponding Transport Block (TB) of data information, TB 0 and TB 1 , with each TB being associated with a respective Hybrid Automatic Repeat reQuest (HARQ) process, and with CW 0 having a first Modulation and Coding Scheme (MCS), MCS 0 , and CW 1 having a second MCS, MCS 1 , and wherein the UE multiplexes control information of O bits with data information in all spatial layers, the method comprising the steps of: computing by the UE, an average MCS from the first MCS MCS determining by the UE, the number of coded control information symbols Q′ in each spatial layer to be proportional to a product of a number of the control information bits O and a parameter β wherein the parameter β
