Narrow bandwidth device in a broadband network

摘要

Technology for communicating with a narrow bandwidth wireless device in a broadband network is disclosed. One method can include the wireless device retrieving at least one of secondary narrow bandwidth device region (NBDR) configuration information or primary NBDR configuration information from a primary NBDR located in a physical downlink shared channel (PDSCH) region of a subframe. The primary NBDR and the secondary NBDRs can be subsets of frequency resources within a wide bandwidth subframe. The wireless device can receive data in at least one of the primary NBDR and the secondary NBDR based on the configuration information. The primary NBDR can be located in the central part of a signal bandwidth spectrum including direct current (DC) subcarrier. The secondary NBDR can use frequency resources within the subframe not used by the primary NBDR.

主权项

1. A method for communicating with a narrow bandwidth wireless device in a broadband network, comprising:
retrieving at least one of secondary narrow bandwidth device region (NBDR) configuration information or primary NBDR configuration information from a primary NBDR, wherein the primary NBDR and the secondary NBDR are located in a physical downlink shared channel (PDSCH) region of a subframe and are subsets of frequency resources within a wide bandwidth subframe, and at least one of the primary NBDR and the secondary NBDR includes both an NBDR-control channel and an NBDR data channel; and receiving data in at least one of the primary NBDR and the secondary NBDR based on the configuration information, wherein the primary NBDR is located in a central part of a signal bandwidth spectrum including a direct current (DC) subcarrier, and the secondary NBDR uses frequency resources within the subframe not used by the primary NBDR.
