One is cooperative relaying [14 16], where relays cooperate to improve the source destination channel quality.
Another example of network optimization is cooperative communication, where multiple nodes in the network cooperate to improve their error performance.
He adds that last week he sent a letter to the chancellor – unanswered so far – offering to cooperate to improve British productivity.
We proposed a coordinated multipoint transmission technique to enable femtocells to cooperate to improve the network's coverage and capacity.
For instance, Osarenkhoe described how Nokia, Ericsson, and Motorola cooperated to improve the Chinese telecom infrastructure while competing on the same market with different mobile devices [21].
On the other hand, spontaneous networking nodes are willing to further cooperate to improve QoS by better exploiting the currently available networking opportunities.
At last, we proposed a coordinated antenna patterns selection scheme to implement fast resource management for femtocell networks, and make multiple femtocells to cooperate to improve the resource utility and system performance of femtocell networks.
The interference from the strongest interfering BSs that can cooperate to improve the SINR of UE n depends on interference scenario j, and thus, the muting pattern, as I_{n,l,j}^{text{si}}left alpha_{n,m'!,l,j}right) = sumlimits_{m' in mathcal{I}_{n}'} (1-alpha_{n,m'!,l,j}),p_{n,m'!,l}.
In the considered scheme, P MTs share the same physical channel (i.e., the information from all MTs is transmitted at the same frequency band) and, in general, there are R≥P BSs which receive the MTs signals and can efficiently cooperate to improve the system's performance.
Theory predicts that Wolbachia and its hosts should cooperate to improve the transmission of infection to offspring, because only infected eggs are protected from the effects of CI.
