Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.

Abstract: Aspects relate to signaling at least one relaying parameter for a wireless communication device that supports relaying operations. In some examples, the wireless communication device may send such a relaying parameter to a scheduling entity. The scheduling entity may then schedule a relaying operation for the wireless communication device based on the relaying parameter. For example, the scheduling entity may select the resources to be used for the relaying operation based on the relaying parameter. In some examples, a relaying parameter may indicate one or more of a relaying capability of a wireless communication device, an operational condition (e.g., requirement) for relaying by a wireless communication device, a relaying configuration for a wireless communication device, or a combination thereof.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for dynamically updating a set of cells activated to serve a user equipment (UE) and the cell in the set of cells designated as the primary cell (PCell). An example method includes receiving signaling indicating a set of cells supported by one or more distributed units (DUs) under a common central unit (CU); identifying a subset of the set of cells activated to serve the UE, wherein a first cell of the activated cells comprises a primary cell selected from cells included in a candidate set of primary cells (PCells); and identifying another one of the activated cells to serve as the PCell if the first cell is re-designated as a secondary cell (SCell), wherein the other one of the activated cells comprises a cell selected from the candidate set of PCells.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring reference signal (RLM-RS) determination using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications from a UE generally includes determining resources to monitor for radio link monitoring (RLM) prior to being configured with resources to monitor for RLM after establishing a radio resource control (RRC) connection with a network, and performing RLM based on the determined resources.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive, from a network entity, a control message for a radar reference signal (RRS) configuration associated with the wireless device. The wireless device may set a timing pattern for the RRS based on the control message and one or more timing parameters for the RRS configuration. The wireless device may transmit the RRS according to the timing pattern. The RRS may include one or more cyclic prefix (CP) sub-symbols and one or more RRS sub-symbols. The wireless device may receive one or more reflections of the RRS and may perform one or more processing operations on the one or more reflections of the RRS using a plurality of sampling windows. A quantity of sampling windows may be equal to a quantity of CP sub-symbols.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.

Abstract: Apparatus, methods, and computer-readable media for facilitating indicating cancelation of transmissions of sidelink messages are disclosed herein. An example method for wireless communication at a sidelink device includes transmitting SCI reserving a set of resources for one or more retransmissions of a message, the set of resources identifying one or more reserved resources in a time domain. The example method also includes identifying a skipped transmission associated with one or more of the set of resources reserved by the sidelink device. Additionally, the example method includes transmitting a cancelation indication indicating the skipped transmission, the cancelation indication indicating that the skipped transmission corresponds to a previous reserved resource in the time domain, a current reserved resource in the time domain, or a future reserved resource in the time domain.
