    Abstract: Methods, systems, and devices for wireless communications are described. A parent wireless node may determine that low latency communications having a latency below a threshold are to be performed with a child wireless node. The parent wireless node may modify, by at least one of the first communication link interface of the parent wireless node, or a second communication link interface of the parent wireless node that is different from the first communication link interface, or a combination thereof, a previously configured resource type for the first communication link interface based at least in part on the low latency communications. The parent wireless node may transmit, from the first communication link interface of the parent wireless node, a grant to the child wireless node indicating that the low latency communications are to be performed.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.

    Abstract: A RACH preamble is transmitted from a UE using multiple antenna ports. A UE splits a data stream containing a RACH preamble into multiple streams corresponding to a same number of antenna ports of the UE. The UE multiplexes the copies of the RACH preamble according to a multiplexing scheme that enables a receiving eNB to discern the different channels used to transmit the signal from the different antenna ports. A RACH procedure is further accomplished in two steps instead of four by the UE then splitting a RACH payload to the same number of streams and multiplexing the RACH payload for transmission to the eNB. The eNB receives both transmissions, and may use the RACH preamble as a reference signal, and responds with a combined message with control information, random access response, and contention resolution information.

    Abstract: Methods, systems, and devices for wireless communications are described. In some integrated access and backhaul (IAB) systems, wireless devices may join the system through an initial integration procedure. For example, a base station may power up and detect a reference signal transmitted by a neighboring base station, and may establish a first beam pair link with this base station. In many cases, this first beam pair link may be a relatively “weak” beam pair link according to an associated quality metric. To improve the link, the integrating base station may transmit an indication of a characteristic (e.g., location or categorical information) of the integrating base station over the first beam pair link, and both base stations may perform beam training based on this characteristic. The base stations may establish a second beam pair link with a greater quality metric than the first beam pair link using this beam training.

    Abstract: An apparatus is provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.

    Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may set different transmission rates for different transmission directions, and may transmit initial access signals based on the transmission rates in the different transmission directions The apparatus may be a base station. The base station determines transmission rates for a plurality of transmission directions, where each transmission rate is determined for a respective transmission direction of the plurality of transmission directions. The base station transmits at least one initial access signal in each of one or more of the plurality of transmission directions based on a corresponding transmission rate of the transmission rates.
