  • Publication number: 20130051289
    Abstract: A method for partitioning a soft buffer in a time-division duplex system and an apparatus using the same are disclosed. The method includes the following steps. A total number of soft channel bits, a maximum number of transport blocks transmittable to a user equipment (UE) in a transmission time interval (TTI), a maximum number of downlink (DL) hybrid automatic retransmit request (HARQ) processes, and a configured maximum number of HARQ processes are determined. A partition size of the soft buffer is selected according at least to the total number of soft channel bits, the maximum number of transport blocks transmittable to the UE in the TTI, the maximum number of DL HARQ processes, and the preconfigured maximum number of HARQ processes.

  • Publication number: 20120275397
    Abstract: A method of handling a soft buffer of a mobile device in a wireless communication system is disclosed. The mobile device is configured a plurality of component carriers (CCs) by a network of the wireless communication system. The plurality of CCs comprise a primary CC (PCC) and at least one secondary CC (SCC). The method comprises determining a plurality of weightings corresponding to the plurality of CCs according to an indication; determining a plurality of sizes of a plurality of sub-blocks according to the plurality of weightings; and dividing the soft buffer into the plurality of sub-blocks according to the plurality of sizes of the plurality of sub-blocks, to arrange a plurality of hybrid automatic repeat request (HARQ) processes of the plurality of CCs in the plurality of sub-blocks.

  • Publication number: 20120192026
    Abstract: Methods for data transmission management used in a transmitter are provided. The method comprises the steps of: encoding M uncoded packets into N coded packets with Q-packet error correction capability using concatenated encoding, where M?N, and Q?1; sequentially transmitting a set or all of the N coded packets to the at least one receiver; receiving at least one feedback information from the at least one receiver, wherein the at least one feedback information comprises at least one ACK or NACK information for indicating decoding statuses of the transmitted coded packets, each of the transmitted coded packets having one of the decoding statuses corresponding thereto; and determining whether to perform a retransmission procedure to retransmit a dedicated packet to the at least one receiver according to collected ACK/NACK included in the feedback information.

  • Publication number: 20110292891
    Abstract: UE-specific search spaces (UE-SS) for a carrier-aggregated communication system are introduced to decrease the number of blind decoding attempts, decrease downlink control information (DCI) blocking probability, and maintain good blind decoding performance. In the proposed control channel allocation method, the control channel searching method and the communication apparatus thereof, the UE-specific search spaces are extended except control channel element (CCE) aggregation level one. Further, a new CCE aggregation level is created in the UE-specific search spaces. The sum of the number of control channel candidates for all aggregation levels is bounded by the maximum number of PDCCH candidates. In addition, uplink MIMO grant command is just allocated in a pre-configured component carrier or a set of pre-configured component carriers, but uplink MIMO grant command is not allocated in the remaining component carriers.

  • Publication number: 20100239032
    Abstract: A method for a first user terminal to receive data from a second user terminal, wherein the first and second user terminals communicate with a transmitting terminal. The method includes: transmitting a first message to the transmitting terminal; receiving a signal from the transmitting terminal, the received signal including information regarding the first message and a second message transmitted from the second user terminal to the transmitting terminal; and decoding, based on the first message, the received signal to receive the second message.
