Abstract: Determining, at a base station, to modify at least one parameter associated with semi-persistent scheduling (SPS) of traffic for one or more user equipments (UEs). Generating a reconfiguration control message to transmit to the one or more UEs to signal the modification of the at least one parameter. The reconfiguration control message is one of a reconfigured downlink control information (DCI) that modifies an activation DCI or a redesigned format for DCI or MAC-CE. Transmitting the reconfiguration control message to the one or more UEs.

Abstract: Certain aspects of the present disclosure provide techniques for selectively activating physical downlink control channel (PDCCH) repetition for retransmissions in wireless communications systems. In an exemplary method, a base station (BS) may transmit, without repetition, a physical downlink shared channel (PDSCH) to a user equipment (UE) in a set of initial transmissions in a period of a transmission cycle; and activate repetition including multiple transmissions for physical downlink control channels (PDCCHs) in a potential retransmission slot for the UE during the period.

Abstract: Systems and methods establishing and maintain a direct User Equipment to User Equipment communication link are disclosed. A User Equipment (UE) may receive a Sounding Reference Signal (SRS) from a neighboring UE. The UE may determine from the SRS that the UE is a good candidate for a direct link. The UE may also determine from the SRS an ID associated with the neighboring UE. The UE may send a direct link request to the UE serving gNB. The serving gNB may forward the request to a gNB serving the neighboring UE. The gNBs may negotiate a joint schedule for a beam a UE to UE beam search. The beam search may be conducted using SRS resources. The results of the beam search may be sent to the gNB and the gNB may determine a beam pair for a direct link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and/or a base station (BS) may identify in connection with a link failure of a primary cell, a resource in a secondary cell. The UE and/or the BS may communicate control signaling with the BS using the resource in the secondary cell as a response to the link failure of the primary cell. Numerous other aspects are provided.

Abstract: A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement procedures including dynamic signaling and/or selection of beam-switching latency for beam refinement procedures using inter- and/or intra-antenna module beam switching. A method by a base station (BS) includes configuring a user equipment (UE) with one or more reference signal (RS) resource sets. Each of the one or more RS resource sets is associated with a first or second type of beam refinement procedure. The BS receives an indication from the UE of at least a first latency and a second latency, longer than the first latency. The BS dynamically selects, for each RS transmission using one of the configured resource sets, the first or second latency. The BS sends the RS transmissions at the selected latency with respect to downlink control information (DCI) triggering the RS transmissions for the first or second type of beam refinement procedure.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication comprising repetitions that provide a solution to the problem of identifying and refining a repetition configuration at a transmitter. A transmitter receives repetition configuration information from a receiver and transmits repetitions of a signal to the receiver based on the received repetition configuration information. The repetition configuration information comprises an indication of at least one of a repetition frequency hopping indicator, at least one beam index, a repetition type or whether repetition is enabled.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication by a wireless device with a first AP are provided. In one aspect, an apparatus is configured to receive a valid Overlapping Basic Service Set (OBSS) PPDU transmission, e.g., transmitted by a second wireless device to a second AP. The apparatus may regard the valid OBSS PPDU as not having been received when a received power of the OBSS PPDU is below an OBSS Packet Detection (PD) level, and determine a transmission power (TXPWR) for a reuse transmission from the wireless device to the first AP based on an OBSS Packet Detection (PD) threshold and based on a TXPWR definition.
