Radio resource allocation in a narrowband communication system
摘要
說(shuō)明書(shū)
In another system-level consideration, any cell-specific resource allocation structure may or may not be communicated to other network devices that are not associated with a particular cell implementing the specific resource allocation structure. Accordingly, in some examples, the possible uplink resource allocation configurations of a cell (or sector, or any other discrete service area maintained by a particular radio network node 10) are not specified explicitly in a predefined manner and not communicated within the network. It is then up to an individual scheduler (i.e., a radio network node 10 or a scheduling component therein) to determine the allocations in line with the possible configurations allowed by constraints described herein. However, this does not guarantee the mitigation of inter-cell interference since one or more radio network nodes (or schedulers) can also allocate uplink radio resources freely (i.e., without being limited by the scheduling constraints presented herein).
In other embodiments, the uplink resource configurations are not specified explicitly in a predefined manner, but are communicated across radio network nodes 10 via the X2 interface (i.e., inter-eNodeB interface). The radio network nodes 10 can then determine uplink resource configurations and associated possible resource allocations that can help mitigate inter-cell interference.
In another embodiment, the NB-PUSCH resource configurations are specified explicitly and/or signaled using control information signaling (e.g., system information or other RRC signaling). Such an implementation is described, for example in the embodiments of
