DEVICE AND METHOD OF SUPPORTING REDUCED DATA TRANSMISSION BANDWIDTH

摘要

An eNodeB (eNB), user equipment (UE) and method for operating using a reduced data transmission bandwidth are generally described. The UE may receive downlink control information (DCI) that provides a resource allocation (RA) of a reduced physical resource block (PRBmin) of less than 1 PRB for communications in a PRB of a subframe. Whether the RA is localized or distributed may be predefined, configured via system information block or Radio Resource Control signaling, or indicated in the DCI format. The DCI format may specify the resources within the PRB allocated to the UE through a subcarrier block index and total number of subcarrier blocks or a bitmap corresponding to a unique block of subcarriers or block index. An order in a list of cell Radio Network Temporary Identifiers (RNTIs) may be used with a common RNTI to derive the reduced RA from a 1 PRB RA.

1. User equipment (UE) comprising:
a transceiver configured to transmit signals to and receive signals from an enhanced Node B (eNB) in a network; and processing circuitry configured to:
receive downlink control information (DCI) from the eNB, the DCI configured to provide a resource allocation comprising a reduced physical resource block (PRBmin) of less than one PRB for at least one of downlink (DL) and uplink (UL) communications in a PRB of a subframe, wherein the PRB comprises 12 wide subcarriers or 24 narrow subcarriers in frequency, and wherein the PRBmin comprises either fewer than 12 wide subcarriers or fewer than 24 narrow subcarriers; andconfigure the transceiver to communicate with the eNB using the resource allocation.
