  • Patent number: 10764833
    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).

  • Patent number: 10757718
    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipment (UEs). The base station may transmit an indication of the reassigned resources in a transmission time interval (TTI) that is subsequent to a TTI reassigned (or punctured) for low latency communications (e.g., a post indication). The base station may transmit the post indication in a retransmission grant of a physical downlink control channel (PDCCH) or in downlink control information (DCI) of a PDCCH.

  • Publication number: 20200266932
    Abstract: Methods, systems, and devices for wireless communications are described that provide for acknowledging receipt of a transmission, or triggering a retransmission, based on an initial decoding or measurement of the transmission. A user equipment (UE) may receive a downlink transmission and perform initial decoding or a measurement on the downlink transmission to determine an initial feedback for the downlink transmission. The initial feedback may be provided to a base station in a first set of uplink resources configured for initial feedback transmissions. The base station may receive the initial feedback, and may initiate a retransmission of the downlink transmission before a final feedback determination is made at the UE. In cases where a UE transmits an uplink transmission, the base station may perform initial decoding and may allocate retransmission resources to the UE prior to completing a final decoding of the uplink transmission.
