摘要:
A wireless transmit/receive unit (WTRU) and a method implemented in the WTRU for receiving a plurality of messages from a base station. The messages include an indication of a synchronization signal (SS) and physical broadcast channel (PBCH) (SS/PBCH) block to be monitored. The SS/PBCH block may be used by the WTRU to acquire the primary synchronization signal (PSS) and secondary synchronization signal (SSS) at a fixed location within the indicated SS/PBCH block. Next the WTRU may acquire one or more PBCHs and then an entire SS/PBCH block based on the determined SS/PBCH block type. The SS/PBCH block includes 4 symbols and the PBCH may be located on 3 of the 4 symbols and the PSS and SSS are each located on a different one of the four symbols from each other. The PBCH symbols may each include its own frequency-multiplexed demodulation reference symbols (DMRS).

Aspects of the present disclosure provide techniques for dynamic channel selection for devices communicating via neighbor aware network (NAN) data link (NDL). As described herein, a NAN apparatus may evaluate a condition of one or more channels available for use by other devices of a cluster and the apparatus, select one of the one or more channels as an operating channel for the cluster and the apparatus based, at least in part, on the evaluated condition, and output an indication of the selected operating channel for transmission to the other devices in the cluster. The operating channel may be dynamically selected after determining a current operating channel has deteriorated, is unusable, and/or if performance of the current operating channel falls below a threshold. According to aspects, a channel hopping schedule may be used by devices communicating via the NDL to switch operating channels.

REGs are mapped to REs for UEs to all available OFDM symbols for a subframe, which includes a time-frequency resource space comprising the OFDM symbols in time and subcarriers in frequency. The mapping is performed to form a portion of a control channel and the available symbols are OFDM symbols not used for another control channel. The REs are populated in the portion of the control channel with control information for the UEs using corresponding ones of the REGs. The mapping and the populating are performed to form a complete control channel over one or more subframes, wherein the complete control channel can span a single subframe or multiple subframes. The one or more subframes with the complete control channel are transmitted. A UE will blind decode received subframe (s) in order to determine the control information, which is to be subsequently used by the UE to receive or transmit data.

A user equipment (400) comprising a narrowband receiver (12) is configured to search among different possible narrowband allocations (16) for a narrowband carrier (14) having a specific characteristic. The narrowband receiver (12) in particular is configured to search a wideband frequency grid for a narrowband portion of a wideband carrier (20) that the narrowband carrier (14) is permitted to lie in-band with or adjacent to, to obtain one or more candidate wideband gridpoints (18). The narrowband receiver (12) prioritizes one or more of the possible narrowband allocations (16) based on their proximity to the one or more candidate wideband gridpoints (18). The narrowband receiver (12) then searches among the different possible narrowband allocations (16) for the narrowband carrier (14) having the specific characteristic, based on the specific characteristic and that prioritization.
