    Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

    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: Wireless communications systems and methods related to system information communications and decoding are provided. In one embodiment, a wireless communication device receives one or more known bits. The wireless communication device receives a first encoded information block. The wireless communication device decodes the first encoded information block to generate a first information block based on the one or more known bits. In one embodiment, a wireless communication device receives a first encoded information block including a first bit pattern. The wireless communication device receives a second encoded information block including a second bit pattern. The wireless communication device jointly decodes the first encoded information block and the second encoded information block based on an assumption that a difference between the first bit pattern and the second bit pattern is within a subset of a plurality of bit-change patterns.

    Abstract: A method for obtaining flight path information comprises: receiving, at a network entity, a capability report indicating a capability of a UE to report a flight path of the UE; and transmitting, from the network entity, a flight path report message that requests the UE to provide: partial-path reporting by reporting first flight path information indicative of a portion of the flight path of the UE that is less than all of the flight path; or triggered reporting by reporting second flight path information in response to occurrence of a trigger event, the second flight path information indicative of at least some of the flight path of the UE; or differential reporting by reporting third flight path information indicative of a difference between a present flight path of the UE and a previous flight path of the UE; or any combination thereof.
