This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.

Disclosed is a wireless communication device including a wireless transceiver, a Bluetooth (BT) transceiver and a BT controller. The wireless transceiver supports at least one wireless communication standard (e.g., at least one of a series of IEEE 802.11 standards) and executes wireless communication via a wireless channel in a period of time. The BT transceiver executes BT communication via a plurality of BT channels successively in the period of time. The BT controller determines that a central-frequency difference between the wireless channel and a BT channel falls within a frequency interval of N predetermined frequency intervals and thereby controls the BT transceiver to use a set of parameters related to the frequency interval, wherein the set of parameters is one of N predetermined sets of parameters.

A method includes determining, by a user equipment (UE), to use a first radio access technology, and triggering, by the UE, a first event to disable a second radio access technology while the UE currently uses the second radio access technology. The first event indicates that a base station fails to configure a secondary cell or instructs the base station to delete a configured secondary cell. The secondary cell is a secondary cell of the second radio access technology on the unlicensed spectrum.

A method includes receiving an absence schedule and storing the absence schedule in a memory. The absence schedule indicates a plurality of absence periods during which a group owner device in a wireless network will be unavailable for receiving transmissions in a frequency band. The method further includes controlling a primary radio transceiver of a wireless device based on the absence schedule, receiving a first request from a secondary radio transceiver of the wireless device to transmit a first wireless message in the frequency band, and granting the first request in response to determining based on the stored absence schedule that a transmission time of the first wireless message is within one of the plurality of absence periods.

A multi-radio device includes two or more radio subsystems coupled to a packet traffic arbitration (PTA) module. The PTA module receives a first request for radio communication from a first radio subsystem, where the first request indicates a first usage duration. After granting the first request, the PTA module receives a second request for radio communication from a second radio subsystem. The second request indicates a second usage duration. The PTA module sends a rejection of the second request to the second radio subsystem, where the rejection indicates a remaining time of the first usage duration.

A method and apparatus are disclosed from the perspective of a network. In one embodiment, the method includes the network configuring a first serving cell and a second serving cell to a UE, wherein a first PDCCH scheduling a first PDSCH on the first serving cell and a second PDCCH scheduling a second PDSCH on the second serving cell are transmitted via a CORESET of the second serving cell. The method further includes the network not configuring a CORESET configuration for the first serving cell. Furthermore, the method includes the network indicating the UE to receive and/or monitor the first PDCCH based on CORESET configuration of the second serving cell.

A method for controlling an active time. The method includes: receiving an indication signal sent by an access network device within a DRX active time; and determining, based on IDC related information of the terminal, whether to extend the DRX active time after receiving the indication signal.

A method of a user equipment (UE) operating with a new radio (NR) radio access technology (RAT). The method comprises receiving synchronization signals and a master information block (MIB) in a first bandwidth (BW) and receiving a physical downlink control channel (PDCCH) in a second BW, wherein the second BW is indicated by an offset in the MIB relative to the first BW and the PDCCH conveys a downlink control information (DCI) format that configures a reception of a first system information block (SIB).

[Object] To simplify the operation of a terminal device for performing D2D communication in which the same communication scheme as the communication scheme of cellular communication is adopted. [Solution] Provided is a terminal device including: a detection unit configured to detect a synchronization signal for wireless communication with a base station; and a control unit configured to control transmission of a synchronization signal for inter-device communication. A radio frame used in the wireless communication with the base station and a radio frame used in the inter-device communication have a same frame structure. A timing of the synchronization signal for the inter-device communication in the same frame structure is same as a timing of the synchronization signal for the wireless communication with the base station in the same frame structure.

Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.
