Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARM) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and more specifically to search space configuration in systems utilizing devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. An example method generally includes receiving a physical random access channel (PRACH) signal from a first user equipment (UE) on a first narrowband region within a wider system bandwidth and transmitting, in response to the PRACH signal, a random access response (RAR) signal in a first search space in a second narrowband region in at least a first subframe.

Abstract: Apparatus, methods, and computer-readable media for facilitating serving aperiodic traffic over sidelink using resource adaptation of periodic resource reservations are disclosed herein. An example method for wireless communication at a first device includes reserving periodic resources for sidelink transmission. The example method also includes modifying the reserved periodic resources within a period based on a traffic load for the period. The example method also includes transmitting sidelink communication in the period based on the modified periodic resources. Another example method of wireless communication at a wireless device includes receiving a periodic resource reservation for sidelink transmission. The example method also includes receiving a modification of the periodic resource reservation for a period. Further, the example method includes transmitting or receiving sidelink communication in the period based on a modified periodic resource.

Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. A device may perform rate splitting on a first message for a first user equipment (UE) and a second message for a second UE, the first message comprising a first private portion and a first common portion, and the second message comprising a second private portion and a second common portion. The device may combine the first common portion and the second common portion into a third common portion. The device may generate cyclic redundancy check (CRC) parity bits associated with at least one of the first private portion and the third common portion and attach the generated CRC parity bits to one or more blocks associated with the transmission. The device may transmit the first private portion and the third common portion to the first UE, and the second private portion and the third common portion to the second UE.

Abstract: Method and apparatus for configuring a UE with a relay measurement configuration for measuring one or more candidate relays in preparation of switching to a target relay. The apparatus receives, from a source relay, a candidate relay configuration. The candidate relay configuration including information of candidate relays and a relay measurement configuration. The apparatus measures a reference signal of the source relay and each of the candidate relays based on the candidate relay configuration. The apparatus transmits, to the source relay, a measurement report of the reference signal of the subset of candidate relays. The apparatus establishes a connection with a subset of candidate relays. The apparatus receives, from the source relay, a relay switch command to switch to a target relay from the subset of candidate relays.

Abstract: Methods, systems, and devices for wireless communications are described in which a network entity may output one or more transmissions as part of a beam sweeping operation using transmission parameters that consume less power, less system resources, or both. One or more transmission parameters, such as a modulation and coding scheme, amount of occupied resources, or any combinations thereof, may have a first value on a first subset of the set of system information messages, and a different value on a different subset of the set of system information messages. A synchronization signal block (SSB) transmission associated with an instance of a system information message may provide an indication of the one or more transmission parameters of the system information message. A receiving device, such as a user equipment (UE) may attempt to decode the system information message based on the indication provided in the SSB.
