1. A communications apparatus, comprising:

  • a first radio module providing a first wireless communications service and communicating with a first communications device in compliance with a first protocol;

    a second radio module providing a second wireless communications service and communicating with a second communications device in compliance with a second protocol; and

    a Co-Located Coexistence (CLC) radio manager detecting activities of the first radio modules, obtaining a first traffic pattern describing downlink and/or uplink traffic allocations of the first radio module from the first radio module, and generating a second traffic pattern of the second radio module according to the first traffic pattern to coordinate operations of the first and second radio modules,wherein the second traffic pattern describes recommended downlink and/or uplink traffic allocations to a plurality of sub-frames for the second radio module, and wherein each sub-frame defined by the second protocol comprises a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols,wherein the second traffic pattern is a sub-frame bitmap describing recommended downlink and/or uplink traffic allocations for the sub-frames by a bit sequence, wherein each bit of the sub-frame bitmap set to a first logic level indicates that the second communications device is recommended to not allocate downlink and/or uplink traffic for the second radio module during the corresponding sub-frame, and each bit of the sub-frame bitmap set to a second logic level indicates that the second communications device is free to allocate downlink and/or uplink traffic for the second radio module during the corresponding sub-frame.
