Radio resource allocation in a narrowband communication system

摘要
Methods and apparatuses of resource allocation for wireless communication are presented. In an example, a user equipment (12) may contain radio circuitry and processing circuitry such that the user equipment (12) is configured to obtain a set of multiple indices, where each index in the set of multiple indices corresponds to a different uplink resource allocation from a set of uplink resource allocations (11) formed from twelve contiguous subcarriers. In an aspect, the set of uplink resource allocations (11) includes an allocation of the twelve contiguous subcarriers, two allocations of six contiguous subcarriers, four allocations of three contiguous subcarriers, and twelve allocations of a single subcarrier. In a further aspect, the user equipment (12) can receive an index indication corresponding to an index from the set of multiple indices from the base station (10). Also, the user equipment (12) can transmit data to the base station (10) using the resource allocation corresponding to the received index indication.

In some case described above the number of combinations is not a power of two. In this case the representation of the number of combinations using a bit string may result in some potentially unused bit string values in the DCI (e.g. when three possible resource allocations are indicated using two bits in the DCI). In one embodiment these otherwise unused values are used to indicate NB-PUSCH frequency resource allocations outside the UE's default PRB (or ‘anchor PRB’), i.e. to indicate allocations in secondary PRBs. This can be useful in an NB-IoT system that makes use of multiple PRBs either for frequency multiplexing different UEs or for serving a UE with a wider channel bandwidth than a single PRB.
