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.

說明書

Additionally, the index indication can be received in any type of downlink message (including but not limited to broadcast/multicast messages and dedicated control channel messages). These messages may include, but are not limited to, at least one system information block (SIB) transmitted by the base station, message(s) communicated via radio resource control (RRC) signaling, and/or at least one downlink control information (DCI) message transmitted by the base station. In instances wherein the at least one DCI serves as the message vehicle, it/they may have an associated DCI format of N0, though not limited to such a format in all cases.

FIG. 6 presents an example method 600 implemented by a base station 10 (also referred to herein as radio network node 10) for performing wireless communication with a user equipment 12 in a narrowband communication system.
