Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit, to a user equipment (UE), a configuration including a parameter indicating a quantity of scheduled measurement gaps that may be used for performing measurements. The UE may apply the parameter by suppressing one or more measurement gaps and may receive data from the network entity via one or more time resources (e.g., a slot, a symbol) associated with the suppressed measurement gaps.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: A first user equipment (UE) that does not support cross-slot scheduling (CSS) and a second UE that supports the CSS may share a paging occasion (PO), and a base station that supports CSS may configure a set of variable K0 greater than zero to the second UE. The base station may page both the first UE and the second UE in the shared PO by transmitting a first paging message for the first UE in the shared PO with K=0, and transmitting a second paging message for the second UE transmitted in the subsequent PO. The first UE may receive a paging scheduling physical downlink control channel (PDCCH) with K0=0 in the shared PO and monitor consecutive POs subsequent to the shared PO to receive the paging message. The base station may also assign separate sets of POs to the CSS-capable UE and the CSS-incapable UE.
