Abstract: Methods, systems, and devices for wireless communications are described that provide for indicating transmit power control information to a user equipment (UE) for semi-persistent scheduling (SPS) transmissions in short transmission time intervals (TTIs) from the UE, and for configuring reference signal transmissions in SPS transmissions of short TTIs. A UE may be configured with uplink power control information for SPS transmissions that use sTTIs that is separate from uplink power control for longer TTIs. A UE may receive the power control information and apply it in SPS transmissions that use sTTIs. Uplink transmit power for SPS sTTI transmissions may be independent of power control for regular sTTI transmissions and independent of power control for long TTI transmissions. UEs may apply a cyclic shift to reference signals transmitted is SPS transmissions according to a SPS configuration, rather than a cyclic shift indicated in a SPS activation command.

Abstract: In narrowband communication, channels may use repetitions in multiple subframes. SPS and DRX for the narrowband communication may not accommodate such repetitions, because repetitions for a channel may fall only partially within a DRX ON duration. An apparatus addresses this problem by determining a DRX ON duration, determining a set of subframes carrying a narrowband PDCCH candidate and determining that the DRX ON duration at least partially overlaps with the set of subframes of the narrowband PDCCH. The apparatus then refrains from decoding the first narrowband PDCCH candidate, decodes the first narrowband PDCCH candidate, or extends the DRX ON duration to include the set of subframes entirely and decoding the first narrowband PDCCH candidate carried in the set of subframes in the extended DRX ON duration. The apparatus may also determine DRX configuration parameters based on parameters of bundled channels, and handle invalid subframes for an SPS grant. X (4 o 0o let0. It 0p 4 C 9u 0 1 4 cc E]~

Abstract: Methods, systems, and devices for wireless communication are described. A base station may broadcast a synchronization signal using a narrowband portion of a bandwidth of a cell. The synchronization signal may include a sequence repeated over several symbol periods using a cover code to support power-efficient cell acquisition. A user equipment (UE) receiving the synchronization signal may determine frequency and timing information for a cell by performing a weighted combination and accumulation of low complexity autocorrelation and cross-correlation procedures on the synchronization signal. The reduced complexity correlation procedures may be enabled based on the use of the cover code and a base sequence. In some cases, the cross-correlation may be performed at multiple sampling rates. The use of the cover code within the synchronization signal may also support correlation procedures that use recursive or repeated updates, which may allow for further reduced computational complexity relative to other cell search procedures.
