  • Patent number: 11323227
    Abstract: Aspects of the disclosure relate to an apparatus and method for wireless communication. The apparatus receives downlink control information (DCI) or a radio resource control (RRC) message indicating a configuration of an uplink burst region of a downlink-centric slot, the configuration allocating resources within the uplink burst region between a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH) or uplink control information (UCI). The PUSCH is multiplexed with at least one of the PUCCH or the UCI in the uplink burst region. The apparatus further generates a feedback signal (e.g., Transmission Control Protocol (TCP) acknowledgement (ACK)) corresponding to a downlink (e.g., TCP) data packet received from a scheduling entity and transmits the feedback signal to the scheduling entity via the PUSCH configured in the uplink burst region of the downlink-centric slot. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 11317354
    Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

  • Publication number: 20220123870
    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: 11310838
    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

  • Patent number: 11309999
    Abstract: Methods, systems, and devices for wireless communications are described that provide improved repetition techniques for autonomous uplink transmissions. Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

  • Publication number: 20220116920
    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.

  • Patent number: 11265114
    Abstract: Methods, systems, and devices for increasing the reliability of low latency transmissions are described. For example, multiple control messages and/or multiple data messages may be transmitted for a single transport block. Explicit and/or implicit signaling may be used to support the repetition of control and data transmissions in a low latency environment. For example, explicit signaling may be used to indicate a correspondence between repeated control and/or data messages. Additionally or alternatively, particular configurations may be used to implicitly signal a correspondence between repeated control and/or data messages.

  • Patent number: 11265876
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use an increased transmit power for one or more instances of an autonomous uplink transmission. For example, a UE may be configured with a repetition window including multiple transmission time intervals (TTIs) and may identify a subset of TTIs within the window that may be unavailable for autonomous uplink transmissions. The UE may adjust transmit power or transmit a scheduling request based on the presence of unavailable TTIs. In some examples, the UE may increase the transmit power by an amount that is based on a number of unavailable TTIs, or a fixed amount, or a combination thereof. In some examples, a UE with limited transmit power (e.g., under a maximum transmit power) may dynamically transmit a report to a base station that includes a request to modify a communications scheme used by the UE.

  • Publication number: 20210410121
    Abstract: Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.

  • Patent number: 11212807
    Abstract: Systems and techniques are disclosed for selecting service-specific cells that considers additional information about service availability at the cells. A base station stores service availability information in system information. A UE searching for a service-specific cell on which to camp receives the system information with service availability. The UE analyzes its service requirements against the service availability as well as measured radio conditions and selects a cell that enables service-specific support on which to camp. When a change occurs to availability of the service support at the base station, it notifies the camped UE of the change and the UE obtains the changed system information to determine whether to reselect a different cell on which to camp. When a service-specific cell is not available, the UE may select a suitable cell for normal service and periodically perform cell reselection in an attempt to again camp on a service-specific cell.
