Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing a configurable circular buffer for rate matched transmissions. The circular buffer may be configured based on a selected mother code rate and a fixed circular buffer length. For example, the respective sizes of the systematic and parity bit sections of the circular buffer may be variable based on the selected mother code rate.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a transmission stream processor used to maintain a lower peak-to-average power ratio (PAPR) for uplink transmissions. In some cases, a UE may map modulated symbols of different signals (or waveforms) to interleaved subsets of frequency resources, and this form of frequency division multiplexing (FDM) may increase the PAPR of an uplink transmission. To reduce the PAPR of uplink transmissions, a transmission stream processor at the UE may support techniques for phase ramping modulated symbols in the time domain prior to mapping the symbols to the frequency resources. These techniques may help to ensure that the signals to be included in an uplink transmission are aligned in such a way that the PAPR of the uplink transmission is reduced.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive an uplink control configuration indication in a downlink control portion of a first slot. The first slot may include the downlink control portion, a second portion, and an uplink short burst portion. The second portion may be located between the downlink control portion and the uplink short burst portion. The apparatus may configure a physical uplink control channel (PUCCH), on at least one of the second portion or the uplink short burst portion of the first slot, for transmission of first uplink control information (UCI) based at least in part on the uplink control configuration indication. The first UCI may correspond to second UCI to be transmitted in the first slot or a second slot. The apparatus may transmit the first UCI on the configured UCI.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate to a base station the number of uplink (UL) component carriers (CCs) that the UE is capable of supporting. A base station may configure the UE for carrier aggregation (CA) and for one or more auxiliary UL CCs. The CA configuration may include CCs for UL data transmissions and the auxiliary UL configuration may include CCs for UL reference signals or random access channel transmissions. The auxiliary UL CCs may thus be used for sounding reference signal (SRS) transmissions even if the UE is otherwise not configured for UL data transmissions on those CCs. UL data transmissions on the CA carriers may be sent at the same time as SRS transmissions or during different transmission time intervals (TTIs), depending on UE capability.

Abstract: Methods, systems, and devices are described for wireless communication. Dedicated frequency resources of a physical random access channel (PRACH) may be designated for large and small frequency hops to facilitate the determination of timing offsets for PRACH transmissions. For instance, a frequency hopping pattern within the PRACH channel having a plurality of single tone transmission may include a first number of hops associated with a first frequency hopping distance (e.g., large frequency hops), and a second number of hops associated with a second frequency hopping distance (e.g., small frequency hops).

Abstract: Narrowband communications in a wireless communications system may include a common synchronization signal, such as a primary synchronization signal (PSS), secondary synchronization signal (SSS), or physical broadcast channel (PBCH). Content of the common synchronization signal may indicate a location of narrowband data transmissions in a narrowband region of a system bandwidth. The location of the narrowband region may be in-band within one or more wideband transmissions, within a guard-band bandwidth adjacent to the wideband transmissions bandwidth, or within a stand-alone bandwidth that is non-adjacent to the wideband transmissions. The common synchronization signal may be located within a predefined search frequency and may include an anchor synchronization channel present in certain resources of allocated narrowband communications resources. Narrowband data region resources may be distributed in other portions of the narrowband communications resources, and may be allocated to different users to provide transmit diversity.

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: Techniques for supporting peer-to-peer (P2P) communication and wide area network (WAN) communication are disclosed. In one aspect, a method operable by a network entity to facilitate peer-to-peer (P2P) communication in a wireless network includes designating a first group of subframes in a wide area network (WAN) uplink (UL) spectrum for WAN communication. The method includes designating a second group of subframes in the WAN UL spectrum for P2P communication. The method further includes allowing P2P mobile entities to use WAN physical layer channels in the second group of subframes to communicate P2P control information and P2P data.
