Abstract: Methods, systems, and devices for wireless communications are described. Random access channel (RACH) occasions may be scheduled on each component carrier (CC) of a carrier aggregation (CA) configuration that includes both a time division duplexing (TDD) TD Raid band and at least one frequency division duplexing (FDD) band based on a synchronization signal/physical broadcast channel block (SSB) received in the TDD band. In some cases, the TDD band may be used to configure the RACH occasions in same and/or different CCs. Additionally or alternatively, the FDD band may configure the RACH occasions on its uplink CC based on SSBs received on other CCs. Additionally, the RACH occasions may be configured such that the UE avoids unavailable uplink slots when transmitting a first RACH message in a RACH occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a negative acknowledgment (NACK) feedback message for a broadcast/multicast communication is to be transmitted. The UE may transmit the NACK feedback message, via a radio access network (RAN), to a broadcast/multicast control plane function device of a core network based at least in part on determining that the NACK feedback message is to be transmitted. The UE may receive a retransmission of the broadcast/multicast communication based at least in part on transmitting the NACK feedback message.

Abstract: Various aspects include methods for supporting Enhancement for Television (ENTV) service delivery to a user equipment (UE) in a fifth generation new radio (5G-NR) radio access network (RAN). Various aspects may include generating an ENTV capability message, the ENTV capability message indicating one or more ENTV parameters of the UE, and sending the ENTV capability message to a Next Generation NodeB (gNB) of the 5G-NR RAN. Various aspects may include receiving a ENTV capability message from the UE, the ENTV capability message indicating one or more ENTV parameters of the UE, determining one or more radio resource configurations for the UE based at least in part on the one or more ENTV parameters of the UE, and generating a configuration message indicating the one or more radio resource configurations for the UE, and sending the configuration message to the UE.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configuring associations between system information of at least one downlink (DL) anchor carrier and at least one random access channel (RACH) occasion (RO) of an uplink (UL) anchor carrier for initial access in flexible multicarrier operations. System information may be transmitted by a base station to a UE over the DL anchor carrier. In aspects, the at least one DL anchor carrier may be mapped to an UL anchor carrier, or to one or more candidate UL anchor carriers from which the UE may configurably select the UL anchor carrier, for initial access operations. In aspects, the UL anchor carrier and/or the one or more candidate UL anchor carriers may be respectively associated with one or more ROs. The UE may perform initial access operations over the UL anchor carrier using the associated one or more ROs.

Abstract: Methods, systems, and devices for wireless communication are described. A device may transmit first control signaling indicating a capability for switching between carriers of a group of carriers during uplink communications using carrier aggregation. The group of carriers include three or more carriers that are each associated with different radio frequency bands. The device may receive second control signaling that includes an indication for the device to switch to a subset of carriers of the group of carriers for transmission of an uplink message. The subset of carriers may be associated with a combination of radio frequency bands. The device may transmit the uplink message on at least one of the subset of carriers in accordance with a mapping between the combination of radio frequency bands and the at least one of the subset of carriers, where the mapping is based on the capability.

Abstract: Embodiments include methods of testing wireless devices for beam forming performance. Various aspects may include determining measurements of communication performance of the wireless device at each of a number of different angular orientations of the wireless device with respect to an antenna within a test chamber, and determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to pass/fail criteria. Further embodiments may include a wireless device testing apparatus configured to perform testing wireless devices for beam forming performance. In some embodiments, a wireless device testing apparatus may include a test chamber, an antenna within the test chamber, a rotatable positioning system within the test chamber configured to hold a wireless device and rotate the wireless device within a range of orientations with respect to the antenna, and a computing device coupled to the antenna and the rotatable positioning system.
