Abstract: Methods, systems, and devices for wireless communications are described. A network entity may output a channel state information (CSI) report message that indicates multiple codebook configurations. A UE may receive the CSI report message indicating a set of codebook configurations associated with a set of antenna port configurations. The UE may transmit a CSI report indicating one or more codebook configurations of the set of codebook configurations, where CSI included in the CSI report is based on the one or more codebook configurations. The UE may then communicate with a network entity based on the channel state information report indicating the one or more codebook configurations.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may select a reference synchronization signal block (SSB) from a set of multiple SSBs that are multiplexed in time and frequency. The UE may select the reference SSB from the set of multiple SSBs based on a rule. The UE may receive a control message that indicates a frequency offset between a reference frequency for a common resource block (CRB) grid and a resource block (RB) that overlaps in frequency with the selected reference SSB. The UE may communicate using the CRB grid in accordance with the frequency offset.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A configuration to determine, by a user equipment, a random access procedure timeline, from multiple random access procedure timelines that each define a different duration between one or more messages that are communicated in a random access procedure can be determined or transmitted. A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: Aspects of the disclosure relate to multiple-input and multiple-output (MIMO) codebook configuration for wireless downlink communications. A user equipment or a scheduled entity receives a reference signal (channel state information reference signal (CSI-RS) and transmits a CSI report based on the reference signal. The CSI report includes a rank indicator configured to indicate one or more ranks among multiple ranks corresponding to multiple antenna panels associated with the reference signal, and a precoding matrix indicator (PMI) corresponding to a codebook for the plurality of antenna panels. In some examples, a first rank of the multiple ranks is different from a second rank of the plurality of ranks. In other examples, a first antenna panel of the multiple antenna panels having a different number of antenna ports than a second antenna panel of the multiple antenna panels. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: A base station may transmit, to a user equipment (UE), an instruction for scheduling a physical uplink shared channel (PUSCH) transmission. The PUSCH transmission may be overlapping with at least one of a slot boundary or a symbol that is configured invalid for a PUSCH by the base station, and the UE may configure a first partial PUSCH and a second partial PUSCH, the second partial PUSCH being a subset of the PUSCH transmission and including a single symbol length. The UE may schedule the second partial PUSCH based on the instruction received from the base station.

Abstract: Methods, systems, and devices for wireless communications are described A user equipment (UE) may receive, from a base station, a first control message that includes a mapping of each security key of a set of security keys to respective security key identifiers. The UE may identify that a first security key identifier is associated with one or more channels to be used for communications between the UE and the base station. In some cases, the UE may receive a control message that schedules communications via the one or more channels. The first security key identifier may be associated with a first security key of the set of security keys. The UE may communicate with the base station using the first security key. The communications with the base station may be secured using the first security key.
