    摘要: An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a first communication, associated with a first subscriber identity module (SIM) operating in a connected mode, that is at least partially overlapping in a time domain with a second communication associated with a second SIM operating in an idle mode. The UE may detect that a transmit chain associated with the first SIM and a receive chain associated with the second SIM are sharing an antenna switch. The UE may perform a preventive action based at least in part on the first communication associated with the first SIM overlapping in the time domain with the second communication associated with the second SIM while the transmit chain associated with the first SIM and the receive chain associated with the second SIM are sharing the antenna switch. Numerous other aspects are described.

    摘要: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first frequency band, a first communication connection on a first subscriber identity module (SIM). The UE may establish, using a second frequency band, a second communication connection on a second SIM in a multi-SIM dual receive mode that includes the first SIM and the second SIM having concurrent activity. The UE may switch from a first antenna to a second antenna for the first SIM in accordance with an antenna switching capability that is based at least in part on whether the first communication connection and the second communication connection are time division duplex (TDD) synchronized. The UE may transmit one or more communications associated with the first SIM using the second antenna. Numerous other aspects are described.
