Abstract:
PROBLEM TO BE SOLVED: To provide more appropriate resource utilization in MBMS (multimedia broadcasts/multicast services). SOLUTION: The present invention includes MBMS reception scheduling for use when a wireless transmit/receive device receives an MBMS service from multiple transmission sources. The sources transmitting the MBMS service data in differing orders. One embodiment uses in-band segmentation information. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To enable a medium access control (MAC) architecture to allow an scheduling entity to start new transmission at any time, and to restart previously unsuccessful transmission at any time. SOLUTION: The MAC architecture determines transmission latency and block error rate requirements for a plurality of data flows, each data flow having associated priority and each data flow comprising a plurality of data blocks. The MAC architecture specifies a scheduling entity (53) that determines a time when transmission is performed, and by which hybrid automatic repeat request (H-ARQ) entity the transmission is performed. H-ARQ entities (52a, 52b) determine whether each prior block has been successfully transmitted, and if not, request the retransmission of unsuccessfully transmitted data blocks.

Abstract:
PROBLEM TO BE SOLVED: To provide a segmenting for a transport block set (TBS). SOLUTION: A radio communication system (shown in Figure) uses an adaptive type modulation and an encoding (34), and has a physical-layer hybrid automatic retransmission demand mechanism (40). The segmenting information of the TBS is provided (46). The TBS is transmitted by using first modulation and encoding scheme. The TBS is received (38), and whether the TBS matches a specified quality is decided. When the TBS does not match the specified quality, a retransmission demand (40) is transmitted. The modulation and an encoding set are changed into second modulation and encoding set. The transmission block set is segmented into a plurality of segments, supported by the second modulation and encoding set (34), in accordance with the segmenting information, in response to the retransmission demand (48), and at least two segments are transmitted separately. A segmenting process may be applied at a plurality of times regarding a specific TBS transmission. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To realize a method for implementing a mobile incoming process, affected by an integration level of WLAN-mobile telephone joint system for various scenarios between user networks. SOLUTION: In a wireless system, having an integrated wireless local area network (12) and mobile telephone network (14), user traffic and a data signal and control data are routed. The data signal and the control data are transmitted to a user equipment (16), based on the type of user equipment and the integration level, that may include change in the incoming mobile session termination. The user traffic is also routed to the user equipment, based on the type of user equipment and the integration level. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To achieve more excellent peer-to-peer communication between radio network controllers (RNC). SOLUTION: A drifting (WTRU) wireless transmit/receive unit has an associated (D-RNC) drift radio network controller 38 and an associated (S-RNC) servicing radio network controller 40. The D-RNC 38 sends a request message to the S-RNC 40 requesting measurements of the drifting WTRU. The S-RNC 40 receives the request message and sends an information message with the requested measurements to the D-RNC 38. The D-RNC 38 receives the information message. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a base station implementing a physical layer automatic repeat demand. SOLUTION: The base station implementing physical layer automatic repeat demand includes a transmitter (38) and a receiver (52). The transmitter has a physical layer transmitter for receiving data, formatting the received data into packets, transmitting the packets and retransmitting packets, in response to failure to receive a corresponding acknowledgment for a given packet, an acknowledgment receiver (56) for receiving the corresponding acknowledgment, and an adaptive modulation and coding controller for collecting retransmission statistics and adjusting the particular data encoding/modulation, by using the collected statistics. The receiver (52) has a physical layer receiver for demodulating the packets, a combiner/decoder (50-1-50-n) for buffering, decoding and detecting packet errors, and an acknowledgment generator for generating an acknowledgment for each packet, if that packet has an acceptable error rate.

Abstract:
PROBLEM TO BE SOLVED: To reduce signaling in assignment of timeslot and code assignment. SOLUTION: In a wireless hybrid TDMA/CDMA communication system for supporting wireless RF communication, at least one time slot is selected, and at least one code is selected in a transmitter to support communication of a user. If a plurality of codes are selected, consecutive codes are selected from among predetermined sequences (54, 56), and the identifier of the at least one timeslot and a first code and a last code among the consecutive codes are signaled (58).
