Abstract: Techniques are described for wireless communication. A first method may include receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal, and monitoring the unlicensed radio frequency spectrum band during the time window to receive a synchronization signal from a base station. A second method may include transmitting an indication of a time window associated with a transmission of a synchronization signal; performing a plurality of clear channel assessments (CCAs) on an unlicensed radio frequency spectrum band during the time window; and transmitting the synchronization signal over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based at least in part on a result of at least one of the CCAs.

Abstract: The disclosure provides for control plane measurements in a wireless device. The wireless device may perform, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management (RRM) measurements of a cell. The wireless device may identify one or both of a first subset of the RRM measurements associated with a first subset of the sub-frames including opportunistic transmissions (i.e. before the transmission, clear channel assessment, CCA, is carried out) and a second subset of the RRM measurements associated with a second subset of the sub-frames including guaranteed transmissions (i.e. before the transmission, clear channel assessment, CCA, is not carried out). The wireless device may determine one or more RRM measurement values (e.g. RSSI, RSRQ) based on one or both of the first subset of the RRM measurements and the second subset of the RRM measurements. The wireless device may similarly perform radio link management (RLM) measurements and determine RLM measurement values based on the first and second subsets. The wireless device may also use timers (e.g. CCA timer, RLC timer) for uplink transmissions to detect radio link failures, RLFs.

Abstract: The present disclosure, for example, relates to one or more techniques for scaling the bandwidth of a carrier. Available sub-channels of an unlicensed radio frequency spectrum band may be determined, and the available sub-channels may be included in the carrier. The available sub-channels may be adjacent or non-adjacent sub-channels. The bandwidth of the carrier may be determined according to which sub-channels are included in the carrier. In this way, the bandwidth of the carrier may be scaled according to the available sub-channels in the unlicensed radio frequency spectrum band.

Abstract: Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A first method includes generating one or both of physical uplink control channel (PUCCH) signals and physical uplink shared channel (PUSCH) signals based on interleaved signals that increase nominal bandwidth occupancy in an unlicensed spectrum; and transmitting the generated signals in the unlicensed spectrum. A second method includes receiving, in an unlicensed spectrum, one or both of physical uplink control channel (PUCCH) signals and physical uplink shared channel (PUSCH) signals based on interleaved signals that increase nominal bandwidth occupancy in the unlicensed spectrum.

Abstract: Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. A method by a base station includes transmitting an RTS signal in an unlicensed spectrum or a V-RTS signal in a licensed spectrum, addressed to a set of UEs, and transmitting a CTS-to-self signal in the unlicensed spectrum, wherein when the V-RTS signal is transmitted, the CTS-to-self signal is transmitted along with the transmission of the V-RTS signal.

Abstract: Methods and apparatuses arc described in which an unlicensed spectrum is used for Long Tenn Evolution (L TE) communications. A first method includes receiving (1705) feedback information from a user equipment. lJ E ( I I 5, I I 5-a, 115-b, 115-c, I I 5-d, I 15-c) via a primary component carrier (PCC) uplink ( 1605) in a licensed spectrum. A second method includes transmitting ( 1715) feedback infixmation f om a UE to an evolved Node B (eNB) via a PCC uplink in a licensed spectrum. The feedback information may address signals transmitted to the UE via a downlink ( 1610) in an uni icensed spectrum. Figure 1
