Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to- detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include a user equipment (UE) determining a capability of the UE for at least one modulation order associated with a first transmission time interval (TTI) and a second TTI that is shorter than the first TTI, transmitting a UE capability message based on determining the UE capability, receiving a message including a parameter and a modulation coding scheme (MCS) index based on the UE capability message, and selecting a modulation table for communicating, to a base station, a transmission associated with the first TTI and the second TTI.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

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: Communications data having a reliability and latency threshold may be transmitted within a legacy downlink control channel. For example, a user equipment (UE) may utilize low latency services, such as ultra-reliable low latency communications (URLLC). In such cases, a base station may transmit URLLC data in a legacy physical downlink control channel (PDCCH) of a downlink transmission time interval. The UE may determine that the PDCCH includes downlink data. The downlink data may have a delay tolerance below the threshold level (e.g., URLLC data), and the determination may be based on a downlink control information (DCI) payload within the received PDCCH. The UE may then receive the downlink data within the PDCCH. In some examples, the downlink data may be received within the DCI payload. Additionally or alternatively, the DCI payload may provide an indication of resources within the PDCCH that are utilized for carrying the downlink data.

Abstract: Title: FEEDBACK TECHNIQUES FOR WIRELESS COMMUNICATIONS (57) : Methods, systems, and devices for wireless communication are de- scribed that provide for generation of an encoded transport block (TB) that includes a number of systematic code blocks (CBs) and a number of parity CBs. The systematic CBs may be transmitted to a receiver, and the receiver may attempt to decode the sys- tematic CBs. In some cases, one or more parity CBs may be transmitted with the sys- tematic CBs, and the systematic CBs may be successfully decoded even in the event that one or more of the systematic CBs are not successfully received. In some cases, a receiver may provide feedback that requests that additional CBs be transmitted to decode the systematic CBs that were received, and it is not necessary to retransmit the missing systematic CBs. In some cases, a quantized value of a number of additional CBs needed to decode the TB may be transmitted. 115, 105-c SOC Cannechum Esrnbbslunent 810 Idendfd TB and CBs fan transn and CB Transm n identify umber of missy a CB Identif for cry ' razed va um b. - of n CB, Feedback Transmisslo .„ iaenriry party CBs for transmissio or CB“o be retrensmined 840 CB' iansmi ssimdCB Bet 84\" Decode TB based on reccid d CBs 8c0 Feedback Transmission W O 20 18/ 1480 24 Al FIG. 8 (12) INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (43) International Publication Date 16 August 2018 (16.08.2018) D IV °nolo DID mil mon mum° oimIE (10) International Publication Number WO 2018/148024 Al WIPO I PCT (51) International Patent Classification: HO4L 1/16 (2006.01) H04L 1/18 (2006.01) HO4L 1/00 (2006.01) (21) International Application Number: PCT/US2018/015229 (22) International Filing Date: 25 January 2018 (25.01.2018) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 62/458,568 13 February 2017 (13.02.2017) US 15/713,335 22 September 2017 (22.09.2017) US (71) Applicant: QUALCOMM INCORPORATED [US/US]; ATTN: International IP Administration, 5775 Morehouse Drive, San Diego, California 92121-1714 (US).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may identify a potential collision between a scheduled legacy transmission time interval (TTI) communication and a scheduled shortened TTI (sTTI) communication, the legacy TTI communication having a legacy TTI duration that is longer than an sTTI duration associated with the sTTI communication. The apparatus may determine whether the legacy TTI communication is within a threshold time of being transmitted. The apparatus may transmit at least one of the sTTI communication, the legacy TTI communication, or any combination thereof, based at least in part on the determination.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.
