Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station in wireless communication with the UE, an allocation of time and frequency resources for an uplink transmission of a first communication type associated with a threshold reliability or latency metric. The UE may monitor a control channel for an uplink preemption indication from the base station, the uplink preemption indication indicating whether the UE should transmit the uplink transmission using the first communication type associated with the threshold reliability or latency metric. The UE may then process the uplink transmission based on monitoring the control channel for the uplink preemption indication.

Abstract: A wireless communications system may support a large number of user equipment (UEs) and a base station may transmit resource configuration information to a group of UEs, in which the configuration information identifies the group of UEs. In some cases, the base station may receive a data transmission from a UE of the UE group that the base station cannot decode. The base station may then transmit a group-common feedback signal to the UE group. Once the transmitting UE of the UE group receives the group-common signal, the UE may re-transmit the data to the base station. By sending a group-common feedback signal, the base station may conserve resources, improve reliability and increase successful uplink transmissions from UEs.

Abstract: Methods, systems, and devices for wireless communications are described. An uplink preemption indication (PI) may be transmitted from a serving cell to a user equipment (UE), where the uplink PI indicates that uplink traffic is to be preempted. In some cases, the UE may communicate with the serving cell on a first component carrier (CC) according to a first time division duplexing (TDD) configuration, where the first TDD configuration includes uplink and downlink portions. The serving cell may transmit the uplink PI on a second CC, and the UE may monitor for and receive the uplink PI during downlink portions of the second CC during uplink portions of the first CC. In some cases, the UE may monitor the second CC in accordance with a frequency division duplexing (FDD) configuration. Additionally or alternatively, the UE may monitor the second CC in accordance with a second complementary TDD configuration.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARM) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

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).

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.

Abstract: In a network configured to communicate over multiple services, each service may have one or more SR configurations. In embodiments, a processor may detects SR collision in which SR occasions for different services as defined by their corresponding configurations at least partially overlap. Based at least on the detected potential collisions, the processor may take action to resolve the collision
