Abstract: Methods, systems, and devices for wireless communication are described to support an indication of one or more carriers of a flexible cell to be used for reception of one or more respective downlink random access messages. A base station may indicate, via system information, a carrier for reception of a downlink control channel scheduling a second random access message. A user equipment (UE) may initiate a random access procedure by transmitting, to the base station, a first random access message. The UE may monitor for and receive the downlink control channel scheduling the second random access message via the carrier indicated in the system information. The UE may receive the second random access message via the same carrier as the associated downlink control channel, or via a different carrier that may be indicated in the system information or in the downlink control channel transmission.

An example method may include transmitting, to a second network entity, a repetition configuration associated with a first PSSCH transmission and a second PSSCH transmission, where the repetition configuration includes information indicative of a frequency hopping pattern associated with the first PSSCH transmission and the second PSSCH transmission. The example method may further include transmitting, to the second network entity, the first PSSCH transmission including a first instance of sidelink information based on the frequency hopping pattern. The example method may further include transmitting, to the second network entity, the second PSSCH transmission including a second instance of the sidelink information based on the frequency hopping pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some examples, the described techniques can be used to perform beam management procedures using a selected configuration of a plurality of configurations, which enables adaptation to changing numbers of channel state information reference signal (CSI-RS) resources. Adapting to changing numbers of CSI-RS resources may enable the network to perform dynamic antenna adaptation, thereby changing the number of active spatial elements used to transmit the CSI-RS resources. Furthermore, signaling the selected configuration enables the network node to change the number of CSI-RS resources at a user equipment (UE) without explicitly reconfiguring the CSI-RS resource set. In some aspects, the UE may determine a configuration including a number of CSI-RS resources using a mapping between the configuration and a configuration of a number of CSI-RS resources for CSI measurement, which enables the UE to determine the selected configuration.

Abstract: A passive multiple-input multiple-output (P-MIMO) method that may be performed by a reconfigurable intelligent surface (RIS) includes applying a first voltage set to one or more unit cells of the RIS for reflecting a downlink signal from a first wireless communication device to a second wireless communication device. The method includes applying a second voltage set to the one or more unit cells of the RIS for reflecting an uplink signal from the second wireless communication device to the first wireless communication device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. Alternatively, the UE may receive, from the network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. The UE may further communicate with the network using the physical channel. Numerous other aspects are described.

Abstract: In an embodiment, a UE determines a timing for a serving cell, obtains a location of a non-serving cell, determines a location of the UE, and estimates a timing for the non-serving cell based at least in part on the timing for the serving cell, the location of the non-serving cell and the location of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for responses to Msg3 PUSCH repetition requests of a UE. In a first aspect, the UE may transmit, to a base station, a request for repetitions of at least one of a PUSCH transmission or a PUSCH retransmission for a random access Msg3 and receive, from the base station, an indication to use one or more fields to determine a number of repetitions of the at least one of the PUSCH transmission or the PUSCH retransmission for the random access Msg3. In a second aspect, the transmitted request may indicate to the base station to use the one or more fields to determine the number of the repetitions of the at least one of the PUSCH transmission or the PUSCH retransmission. The UE may transmit the number of repetitions based on the transmitted indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device (310) may receive multiple reference signals (RSs) from a second device (320) via a plurality of passive devices (410,420), where each RS of the multiple RSs is forwarded individually by one of the plurality of passive devices with a first set of reflection configurations (Slot 502, Slot 504). The first device may receive an additional RS from the second device via the plurality of passive devices, where the additional RS is forwarded jointly by all of the plurality of passive devices with a second set of reflection configurations (Slot 506). The first device may determine information from the plurality of passive devices based on the multiple RSs and the additional RS, where the information is represented by a change between the first set of reflection configurations and the second set of reflection configurations. Numerous other aspects are described.
