Abstract
Embodiments of systems and methods for time domain multiplexing solutions for in-device coexistence are generally described herein. Other embodiments may be described and claimed.
Claims15
A method for wireless communications, comprising:
- determining setup information of a user equipment (UE), wherein the setup information includes identification of a plurality of radios including a first radio and a second radio;
- detecting in-device coexistence interference by the (UE), wherein the UE is configured to communicate by a first radio according to a long term evolution (LTE) protocol and communicate by a second radio according to a wireless fidelity (Wi-Fi) protocol;
- transmitting in-device coexistence interference information to a receiver to suggest a first time-division multiplexing (TDM) pattern, wherein the in-device coexistence interference information indicates a subset of allowed hybrid automatic repeat request (HARQ) processes;
- and
- receiving, by the UE, a discontinuous reception (DRX) configuration to monitor a physical downlink control channel (PDCCH) discontinuously, wherein the DRX configuration comprises a second TDM pattern to operate the first radio during a first duration and to provide an opportunity to operate the second radio during a second duration, wherein the DRX configuration provides a DRX timing granularity of one microsecond, wherein the DRX configuration designates a DRX cycle length matching a beacon interval length of a Wi-Fi network.
