摘要： The present methods and apparatus enable transmission of an interlaced reference signal for two UEs using a comb structure. In some aspects, the present methods and apparatus may allocate resources and indicate whether a first UE and a second UE are to transmit DM-RS with a comb structure in a single slot based on the allocation. Further, in some aspects, the present methods and apparatus may allocate resources and transmit information indicating whether a first UE is to transmit DM-RS in a first slot or in both a first slot and a second slot within a subframe.

摘要： The apparatus enables pilot signals, whether single tone or multiple tone, that achieve a very low PAPR. After receiving an allocation for multiple tones, the apparatus determines a pilot signal for transmission. The apparatus may select tones from the allocation for transmission of a pilot signal based on a pilot pattern. The pilot pattern may comprise a tone sequence that identifies a sequences of tones, wherein each tone in the tone sequence of identifies one tone of multiple tones for transmission of a pilot signal during a given pilot symbol period. The pilot signal may also comprise a signal sequence. The apparatus may generate a set of multi-tone modulated pilot sequences, select a pilot sequence based on a cross-correlation property, and transmit a pilot signal using multiple tones of the allocation using the selected pilot sequence.

摘要： Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

摘要： A method of wireless communication at a serving base station identifies a potential interference condition based on an uplink/downlink configuration mismatch. The method includes signaling, to a neighbor base station, to restrict transmissions based on the identified potential interference condition. The transmissions may be restricted by beamforming the transmissions into a different direction and/or blocking transmissions on a frequency. The signaling prompts the neighbor base station to restrict downlink transmissions that will potentially interfere with uplink control channel transmissions received at the serving base station, or to restrict uplink transmissions, intended for the neighbor base station, that will potentially interfere with downlink control channel transmissions from the serving base station.

摘要： Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to sounding reference signal (SRS) transmissions in enhanced machine type communication (MTC). An example method generally includes determining one or more narrowband regions partitioned from wider system bandwidth for communicating with a base station, determining resources, within the one or more narrowband regions of a first subframe, for transmission of sounding reference signals (SRS) by the UE, deciding whether or not to transmit SRS on the determined resources of the first subframe, and transmitting or not transmitting the SRS on the determined resources of the first subframe based on the decision.

摘要： Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation and other clean-slate, OFDM based systems such as enhanced component carrier (eCC) systems. An example method is provided for operations which may be performed by a BS to generate and transmit a dual-layer PSS, and correspondingly, techniques for a UE to detect the dual-layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to a number of symbols within one or more subframes of a frame.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transitions to a dormant state and transmits a very low duty cycle signal (LDCS) while in the dormant state. The apparatus may transmit an LDCS configuration to a second entity, the second entity being one of an LPN that is not in a dormant state and a macro cell. The apparatus may further monitor for a RACH messages at a predetermined RACH delay after transmitting the LDCS. The apparatus may transition to a DRX/DTX mode. The DRX/DTX mode may be matched to at least one connected UE.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives an LDCS configuration for a UE relay from a second entity and monitors for an LDCS from the UE relay based on the received LDCS configuration. The second entity may comprise one of an LPN that is not in a dormant state and a Macro cell. The apparatus may receive LDCS configurations for a plurality of LPNs and monitor for a plurality of LPNs based on the received LDCS configurations. When the apparatus determines a need to connect to a LPN, the apparatus may select an LPN among the plurality of LPNs.
