摘要： 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.

摘要： Methods and apparatus are provided contention based uplink data transmission. In one novel aspect, the contention-based uplink data channel is used to transmit the data directly to the network. In one embodiment, the UE selects an UL data channel from a set of preconfigured uplink contention based data channels and sends the UL data transmission on the selected UL data channel. In one embodiment, the contention based UL data has a narrow bandwidth with a long CP such that the TA is not needed from the base station. In another embodiment, a small signaling payload is included in the CB UL data transmission if the size of the data contents cannot be fit in the UL data channel. In one embodiment, the signaling payload is the BSR. The UE, subsequently, receives an UL grant and sends the remaining data contents using the allocated data channel in the UL grant.

摘要： A method of scheduling transmitting and receiving communication slots for co-located radio devices is provided. A Bluetooth (BT) device first synchronizes its communication time slots with a co-located radio module, and then obtains the traffic pattern of the co-located radio module. Based on the traffic pattern, the BT device selectively skips one or more TX or RX time slots to avoid data transmission or reception in certain time slots and thereby reducing interference with the co-located radio module. In addition, the BT device generates a co-located coexistence (CLC) bitmap and transmits the CLC bitmap to its peer BT device such that the peer BT device can also skip data transmission or reception in certain time slots affected by the co-located radio module. The skipped time slots are disabled for TX or RX operation to prevent interference and to achieve more energy saving.

摘要： A coexistence interference mitigation method is provided. In a wireless network, a wireless device is equipped with multiple radios in the same device platform. The wireless device also has a control entity that communicates with the multiple co-located radio modules. A first radio module receives a notification from the control entity. The notification informs a critical signaling status of a second radio module co-located with the first radio module. Upon receiving the notification, the first radio module stops uplink transmission due to coexistence interference and transmits a coexistence indicator to its serving eNB. After a certain period, the first radio module receives a second notification that informs a completion status of the critical signaling of the second radio module. Upon receiving the second notification, the first radio module resumes uplink transmission and transmits a coexistence resume indicator to the eNB.

摘要： Carrier pre-assignment is applied in multi-carrier handover operation to mitigate the impact to the user experience during handover and to achieve various objectives of call admission control in wireless multi-carrier OFDM networks. With carrier pre-assignment, a mobile station communicates its multi-carrier information to a target base station. The target base station pre-assigns secondary carriers to fulfill the requirements of the mobile station. In a first embodiment, a break-before-entry (BBE) multi-carrier handover procedure with carrier pre-assignment is provided. In a second embodiment, an entry-before-break (EBB) multi- carrier handover procedures for both inter-FA and intra-FA with carrier pre-assignment are provided. The multi-carrier handover procedures with carrier pre-assignment may be applied to 2-to-2 or N-to-N carriers handover situation. Because target secondary carriers are pre- assigned before handoff, the mobile station is ready for data transmission over multiple carriers after handover without additional carrier assignment procedure.

摘要： A communications apparatus is provided. A receiving module receives a signal with a predetermined signal bandwidth. A low pass filter filters the signal to obtain a filtered signal. A filter bandwidth of the low pass filter is wide enough to pass the regular sub-carrier frequency components and at least half of the guard sub-carrier frequency components of the signal. An analog to digital converter samples the filtered signal with a sampling rate exceeding a standard sampling rate defined in accordance with the predetermined signal bandwidth of the signal to obtain a plurality of digital samples. A Fast Fourier Transform module performs a fast Fourier transform on a predetermined number of points of the digital samples to obtain a plurality of transformed samples. The predetermined number exceeds a standard number defined in accordance with the predetermined carrier bandwidth. A sub-carrier collector collects the data from the transformed samples.
