where PCOD and PDEC are the power required for channel coding and decoding, respectively. Using the expressions in (2) and (3), we can arrive at (13) PSCE in (11) stands for the power required for channel estimation in both the uplink and downlink of the system, and it can be ...
The maximum transmission speed for only 1 user in downlink is calculated as (11) where the primary modulation scheme is 64QAM, the convolutional coding rate is 5/6, and the number of OFDM symbols for data transmission per 1 OFDMA/TDD frame is 23. Because only 23 OFDM symbols are used ...
The common field includes the information for all of the designated users to receive the PPDU in their corresponding bandwidth. The user-specific field consists of the packet size, modulation scheme, and coding level for the packet of the specified user among all simultaneously selected users. The...
(e.g., the UE 100) from the MIMO receiver (e.g., the eNodeB 150). Hence the uplink grant may not contain a PMI field. On the other hand, for CL-SM embodiments, where pre-coding is channel-dependent and dynamically configured by the MIMO receiver, a PMI field is typically ...
The pre-coding vector b is for the single stream mode and is the first column of pre-coding matrix B. For dual stream mode, two sets of combining weights (w1dual,w2dual) are computed. These weights are obtained by solving the following systems of equations (4): ( R u + α PC ...
