    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.

    摘要: A Long Term Evolution Advanced (LTE-A) location server, user equipment (UE) and evolved Node-B (eNB) are generally described. Information may be transmitted to the UE from the location server. The transmission may be triggered by the location server or another entity requesting the UE location. The information may permit the UE to receive a discovery reference signal (DRS) from at least one eNB. The information may contain an indication of measurements to be performed using the DRS. The UE may measure Reference Signal Received Power (RSRP) or Reference Signal Time Difference (RSTD) of the DRS. The UE may send the measurement information to the location server where the UE location is estimated. The UE location may be based on measurements of the DRS and a positioning reference signal (PRS) from one or more eNBs to obtain the Observed Time Difference of Arrival (OTDOA) or Enhanced Cell ID (ECID).

    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.

    摘要: Disclosed in some examples is a method of wireless resource block assignment in a long term evolution wireless network including creating a downlink control information message for a user equipment, the downlink control information message comprising: a resource block assignment field which indicates up to N physical resource blocks scheduled to the user equipment by specifying an index into a plurality of all possible physical resource block allocations of between 1 and N resource blocks, wherein the resource block assignment field comprises at most a number of bits necessary to address all of the possible physical resource block allocations for assignments of 1 to N physical resource blocks, and wherein N is less than a total number of physical resource blocks; and sending the downlink control information over a physical downlink control channel using orthogonal frequency division multiplexing.
