    Abstract: Sounding mechanism for LTE-A systems under carrier aggregation is provided. A UE receives an uplink or downlink grant transmitted from an eNB over a primary carrier in a multi-carrier LTE-A system. The UE determines indicated carrier(s) and detects a triggering condition for aperiodic sounding transmission in the grant. The UE then selects UE-specific sounding reference signal (SRS) parameters. Finally, the UE transmits an aperiodic SRS (ap-SRS) over the indicated carrier(s) using the selected UE-specific SRS parameters. In one embodiment, the uplink or downlink grant is transmitted via a PDCCH carrying various DCI formats. Each DCI format contains a carrier indicator field (CIF) that indicates which carrier is used for ap-SRS transmission if cross-carrier scheduling is enabled. In another embodiment, DCI format 3/3A is transmitted via a PDCCH carrying a plurality of information fields, each field indicates if the UE should enable ap-SRS in a particular carrier.

    Abstract: Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation, a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition, unnecessary re-activation or re-inactivation of a CC is prevented, and explicit feedback for activation/deactivation is considered. For scheduling mechanism, a novel buffer status reporting (BSR) procedure is provided, where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking, various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.

    Abstract: A method for coordinating transmissions between different communications apparatuses in a communications system. The method obtains a sub-frame indicator carried in a first control signal transmitted in a control region of a first sub-frame received from an evolved node B (eNB), wherein the sub-frame indicator indicates resource allocation of one or more sub-frame following the first sub-frame. The method then determines whether a second sub-frame following the first sub-frame and received from the eNB is an almost blank sub-frame according to the sub-frame indicator. When the second sub-frame is not the almost blank sub-frame, obtaining information regarding a start position of a data region of the second sub-frame from a second control signal transmitted in a control region of the second sub-frame.

    Abstract: A communications apparatus is provided. A controller module obtains information regarding a Hybrid Automatic Repeat Request (HARQ) round trip time (RTT) in an HARQ process, arranging one or more almost blank sub-frame(s) in one or more frame(s) according to the HARQ RTT information and generating a sub-frame pattern describing the arrangement of the almost blank sub-frame(s), wherein the HARQ RTT is defined by the communications system. A transceiver module transmits at least a signal carrying information regarding the sub-frame pattern to a peer communications apparatus in the communications system. In addition, at least one almost blank sub-frame in the sub-frame pattern is arranged in a sub-frame for the peer communications apparatus to transmit an uplink grant message for granting an user equipment to transmit uplink data to the peer communications apparatus.
