  • Publication number: 20190349897
    Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

  • Publication number: 20190335480
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

  • Publication number: 20190320454
    Abstract: Certain aspects of the present disclosure provide techniques for physical downlink shared channel (PDSCH) processing in presence of downlink preemption indication (DLPI). A method for wireless communication by a base station (BS) includes determining a feedback timing indicator associated with a PDSCH transmission to a user equipment (UE) in a first slot. The determination is based on a first number of slots from the first slot until transmission of a DLPI to the UE in a second slot and a second number slots for a minimum processing time associated with the UE. The method includes sending downlink control information (DCI) to the UE scheduling the PDSCH transmission to the UE in the first slot. The DCI includes the feedback timing indicator. The UE determines how to process the PDSCH based on the feedback timing indicator.

  • Publication number: 20190320393
    Abstract: Some wireless communications systems may support mobile broadband (MBB) communications and low latency communications. To facilitate low latency communications, a base station may assign resources allocated for an MBB transmission for a low latency transmission. As described herein, to limit interference between an MBB transmission and a low latency transmission while maximizing the chances that the MBB transmission is received, an MBB user equipment (UE) may be configured to adjust a transmit power for the MBB transmission to limit the impact on a low latency transmission without preempting the MBB transmission. However, if the MBB UE is unable to adjust the transmit power for the MBB transmission prior to the MBB transmission, the MBB UE may determine whether to drop a portion of the MBB transmission on the resources assigned for the low latency transmission (e.g., based on whether a received power of the MBB transmission exceeds a threshold).

  • Publication number: 20190288789
    Abstract: Techniques are described herein related to communicating a quality of service (QoS) class identifier (QCI) for configuring physical (PHY) layer signaling. The QCI may be used to configure one or more transmission parameters of a device (e.g., a user equipment (UE) or a base station) at a PHY layer. The PHY layer may select the one or more transmission parameters to meet the QoS conditions of a given QoS class of a transport block being communicated. A modulation and coding scheme (MCS) value may be used as the QCI for the PHY layer, a channel quality indicator (CQI) value may be used as the QCI for the PHY layer, or a cell radio network temporary identifier (C-RNTI) may be used as the QCI for the PHY layer. In some cases, the QCI may be a single bit included in a downlink control message.

  • Publication number: 20190288800
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.

  • Patent number: 10412632
    Abstract: Dynamically adaptive numerologies for ultra-reliable low-latency communications (URLLC) are discussed in which a base station may determine performance characteristics for each user equipment (UE) that it serves, in addition to detecting any fluctuations in system loading at the base station. Based on this information, the base may be select for each of the served UEs an adapted numerology that provides an optimized set of configurations that assist the communications between the base station and each UE to meet the strict parameters for URLLC. Once selected, the base station signals the selected adapted numerology to the UEs either through broadcast or UE-specific communications.

  • Publication number: 20190268923
    Abstract: The described techniques relate to techniques for determining transmission opportunities and utilization of uplink resources by a user equipment (UE) in communication with a base station. In some examples, a base station may transmit a slot configuration to a UE. The slot configuration may indicate the communication link direction (uplink, downlink, or flexible) associated with each symbol in a given slot. A dynamic slot configuration may indicate which of the flexible symbols are uplink symbols and which are downlink symbols and the UE may determine uplink transmission opportunities based on the slot configuration, the dynamic slot configuration, and a grant free uplink type associated with the UE. The UE may transmit an uplink data message to the base station using the determined set of uplink transmission resources.

  • Publication number: 20190268127
    Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.
