摘要： Systems and methods of providing a NPRACH preamble in a multefire system are described. A UE configured for multefire NB-IoT or eMTC operation receives, from an eNB, access information that includes a SIB on a narrowband channel of an unlicensed band. Based on the access information, the UE transmits a NPRACH preamble in two or six contiguous uplink subframes. The NPRACH preamble is transmitted in two or six contiguous subframes. When two subframes are used, four symbol groups each having a 266.7 μs CP and two symbols are transmitted without a gap therebetween. When six subframes are used, four symbol groups each having a 266.7 μs CP and five symbols are transmitted without a gap therebetween.

摘要： Systems and methods of using a frame structure by a NB-IoT UE are described, The UE receives an anchor segment on an anchor channel and a data segment on a data channel both in an unlicensed spectrum. If a 3N1 frame structure is used: a NPSS, NSSS and NPBCH are in a highest index anchor carrier of contiguous anchor carriers and SIB in a lowest index anchor carrier, and if a 3N2 frame structure is used a single narrowband carrier comprising the NPSS, NSSS, NPBCH and SIB. The data channel is a FHSS single carrier other than the anchor carriers if the 3N1 frame structure is used and the single narrowband carrier if the 3N2 frame structure is used. A NPDCCH or NPDSCH is received on a middle index anchor carrier or in the data segment. The NPSS overrides a TDD configuration indicated by the eNB.

摘要： An apparatus and method for CSI reporting in the unlicensed band are described. CRS-RSs are transmitted from a RAN in narrowband data channels in the unlicensed band to an eMTC UE. The UE determines the CQI and PMI from the CRS-RSs and transmits a periodic CSI report to the RAN that contains the CQI and PMI. The periodic CSI report is received at a nsfrel th subframe of a nmframe th mframe, where nmframe satisfies nmframe mod Npd,mframe=NOFFSET,mframe where Nmframe is a reporting period in terms of mframes and NOFFSET,mframe is a reporting period offset in terms of mframes, and nsfrel satisfies nsfrel−20=NOFFSET,CQI where NOFFSET,CQI is a reporting period offset in subframes.

摘要： An apparatus and method for frequency hopping in the unlicensed band are described. A NB-IoT UE receives a MIB from a RAN. The MIB includes a DL/UL configuration for communication with the RAN. Frequency hopping information is preconfigured in the UE. The MIB is received in an anchor segment of a fixed NB anchor channel in the unlicensed band. The frequency hopping sequence is determined based on timing information carried in a PBCH on the anchor channel. Data is communicated between the NB-IoT UE and the RAN in data segments on the data channels in accordance with the frequency hopping sequence.

摘要： The methods and configurations herein provide for analysis of microplate based assays. Certain aspects include: an optical illumination panel; a plurality of sample wells configured to receive light from the optical illumination panel, and wherein the plurality of sample wells is configured with a first field of view; at least one aperture array configured to isolate directed light therethrough the plurality of sample wells; at least one optical array configured to receive optical information from the plurality of sample platforms, wherein the at least optical array comprises an array of individual microprisms configured with equal apex angles at distal equidistances along a row, wherein the individual microprism apex angles decrease toward the center of the row culminating in at least one flat surface along a center portion of the row; and a detector configured to capture the optical information with a second field of view as provided by the at least one optical array.
