... in the downlink and hence (1 − t) is that for the second-hop transmission in the downlink. The end- to-end achievable rate of the two-hop downlink transmission from the kth base station to the ... terminals by virtue of self -interference. The performance of the schemes were not optimized here. For example, given the high transmit asymmetry of the ba...
