    Abstract: A method for performing wireless communication by a first device is proposed. The method may comprise the steps of: transmitting first sidelink control information (SCI) related to initial transmission, to a second device through a first physical sidelink control channel (PSCCH), wherein the first SCI related to the initial transmission includes scheduling information of second SCI related to the initial transmission, which is transmitted through a first physical sidelink shared channel (PSSCH) related to the first PSCCH; transmitting, to the second device, a medium access control protocol data unit (MAC PDU) and the second SCI related to the initial transmission through the first PSSCH, wherein the second SCI related to the initial transmission includes location information of the first device, which is related to the initial transmission; transmitting first SCI related to retransmission, to the second device through a second PSCCH, wherein the first SCI related to the retransmission includes scheduling information of second SCI related to the retransmission, which is transmitted through a second PSSCH related to the second PSCCH; and transmitting, to the second device, the MAC PDU and the second SCI related to the retransmission through the second PSSCH, wherein the second SCI related to the retransmission includes the location information of the first device, which is related to the initial transmission.

    Abstract: Methods, systems, and devices for wireless communication are described. For a user equipment with a number of M greater than or equal to two antennas, a signal is transmitted from at least a first antenna and a second antenna at a first time with an initial relative phase state including a first relative phase rotation between the signals transmitted by the first and second antennas. In response to a determination that a response signal was not received at the user equipment, the signal is retransmitted from at least the first antenna and the second antenna with a subsequent relative phase state among the transmitting antennas, including a second different relative phase rotation, at a second time. The second time may be the next subsequent retransmission of the signal or may be a retransmission following one or more retransmissions using the first relative phase rotation.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may monitor a search space of a control channel for at least one downlink transmission. The UE may perform a plurality of decoding operations on a plurality of decoding candidates associated with the downlink control information format transmitted in a plurality of transmission time intervals (TTIs). In some cases, the plurality of decoding operations may comprise performing a first decoding on a first decoding candidate received in a current TTI, the first decoding operation applying a first descrambling code to the first decoding candidate, and performing a second decoding operation on a combined decoding candidate that comprises soft combined information from the first and second decoding candidate, the second decoding candidate received in a prior TTI.

    Abstract: Methods and systems of managing data transfers in a fixture. One system includes fixtures comprising: a communication interface; and a processor configured to optimize download efficiency by: receiving, from a remote device via the communication interface, a file comprising a plurality of data blocks, wherein each of the plurality of data blocks comprise a unique cyclical redundancy check (CRC) value and a payload; determining, for each of the plurality of data blocks, a check value based on a polynomial division of the respective payload; determining an error in at least one of the plurality of data blocks based on a comparison between each of the respective CRC values and the respective check values; and providing, to the remote device via the communication interface, a request for retransmission of each of the at least one of the plurality of data blocks with the determined error.
