The minimum RB units are pre-allocated to all scheduled UEs when there are not enough resources; otherwise, the average RB per UE obtained in the last step is pre-allocated.
First, the entire tree can be pre-allocated and a function defined to map each position to some node entry.
In one of the scenarios, the spectrum is not pre-allocated to any service in particular (service neutrality) while in the remaining four, blocks of spectrum are pre-allocated to DTT, mobile multimedia and mobile broadband communications.
In order to exploit the benefit of simultaneous transmissions provided by MIMO, researchers have proposed a number of cross-layer optimizations and MAC layer designs to increase the throughput of wireless mesh or ad hoc networks, where the number of elements in the antenna arrays are pre-allocated or evenly assigned to the routers.
PRACHs are pre-allocated to multiple MTC classes by adopting a class dependent backoff procedure.
A motivating real world example could be a sensor network where sensing delays must be limited, data rates may be pre-allocated, and energy consumption should be minimal.
Regarding data traffic, all UEs are pre-allocated the average RBs, unless the required RBs for a user is smaller than the average RBs, in which case the UE is pre-assigned only the required RBs.
In fact, since they are statically placed and they can be connected by a wired infrastructure, service channels can be pre-allocated to RSUs in order to avoid their BSSs to be channel-overlappingc.
The number of points is calculated and memory is pre-allocated using the FillSampleValues function.
Preassignment-and-reassignment algorithms: In preassignment, certain amount of resources, subchannel or power for instance, are initially pre-allocated as base resources to some or all users before the other resources are now optimally shared among the remaining users.
Assume Pmax,b= Pmax for all sectors, and that the total transmit power Pmax in each sector is equally pre-allocated to all the available subchannels.
