For ease of explanation, we assume that all applications considered for resource allocation have the same number of application tiers.
If a feeder link gets negative weight, then it will not be considered for subchannel allocation and this will prevent transmitting data to the corresponding relay buffer.
Delay-based bandwidth allocation algorithms are proposed in [10, 11], where the delay requirements of the connections are considered for bandwidth allocation.
In the following subsections, two cases are considered for the allocation of random access preamble: single traffic and multiple traffic sources [11].
Although SLNR has been widely used for beamforming design in multi-antenna [15] and multi-cell systems [16], to the best of our knowledge, it has not been considered for resource allocation under the HetNet scenario.
Only CT findings were considered for group allocation: animals with lung opacifications other than small, localized dorsal atelectasis were included in the respective opacified group.
Health professionals suggested various performance indicators related to: 1) maternal; 2) neonatal; and 3) facility management to be considered for incentive allocation.
Hence, the hop length, which indicates the SU's mobility, is considered for the channel allocation.
The sensing function identifies the frequency band which is considered for allocation, but it is also needed for detecting possible other PU's starting to operate in the spectral gap during the SU operation.
While when the limited transmit power and the fairness issue are considered for the resource allocation, it is preferable to minimize the total transmit power of the CR network with considering the fairness of power drain of relay SUs.
A number of points should be considered when selecting an allocation method for use in a particular trial.
