Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

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: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: Various techniques for narrowband communications in a wireless communications network are provided. Narrowband communications may be transmitted using a single resource block (RB) of a number of RBs used for wideband communications. In order to provide for efficient device discovery and synchronization using narrowband communications, a synchronization signal, such as a primary synchronization signal (PSS) or secondary synchronization signal (SSS), may be transmitted within the single resource block. The synchronization signal may be transmitted, for example, using multiple orthogonal frequency division multiplexing (OFDM) symbols within the single RB. A common reference signal (CRS) may also be present in the single resource block, which may puncture the synchronization signal, in some examples. In other examples, the synchronization signal may be mapped to non-CRS symbols of the single resource block.

Abstract: Aspects of the disclosure relate to obtaining a duplex mode of a scheduled entity, selecting a downlink-uplink (DU) slot interpretation to be applied by the scheduled entity to a slot including a DU symbol based on the duplex mode of the scheduled entity, and transmitting the DU slot interpretation to the scheduled entity. The DU symbol may be configured to include a downlink transmission and an uplink transmission within a same carrier bandwidth. Other aspects relate to receiving a message, indicating that the slot is formatted with a DU symbol, selecting a DU slot interpretation to be applied to the slot including the DU symbol based on a duplex mode of the scheduled entity, and applying the DU slot interpretation to the slot.

Abstract: Aspects provide for wireless communication between a UE and a radio access network (RAN) node in a wireless communication network. The RAN node may generate a re-synchronization signal (RSS) for a bandwidth part (BWP) of a plurality of BWPs and transmit the RSS in the BWP of a downlink to the UE. A first bandwidth of the RSS may be based on a second bandwidth of the BWP. The UE may receive the RSS in different RRC states and perform a measurement of the RSS for synchronization, for an early detection of a paging or wake-up signal, and/or for radio resource management (RRM) measurements or radio link monitoring (RLM) measurements. The UE may utilize a communication link with the RAN node based on the measurement and the RAN node may utilize the communication link to communicate with a group of UEs sharing at least one same RSS beam.
