  • Patent number: 8804617
    Abstract: A wireless transmission method, a base station, a relay station, and a mobile station using the same methods are proposed. The method is adapted for delivering MBS in a relay system, and includes following procedures. MBS data is transmitted by a base station at a first time point to at least a subordinate mobile station. The MBS data is also transmitted at the first time point or at a later time point from the base station to subordinate relay node(s) thereof. The base station and relay node(s) at an upper hop level decide whether to transmit a duplicate of the MBS data simultaneously with the relay node(s) at a lower hop level when the lower hop level relay node(s) is scheduled to transmit the received MBS data at the later time point. An indicator is used to indicate any two transmissions being identical.

  • Publication number: 20140010172
    Abstract: This disclosure proposes a method to achieve D2D (device to device) communication in LTE system. Traditional communication in LTE systems is based on eNB. UEs (User Equipment) need to connect to eNB to send uplink and downlink transmission. Device to device communication is different from the traditional LTE scheme. UEs may directly connect to other UEs, sending data to each other. The disclosure provides the signaling process, based on LTE network entry procedure, to establish D2D communication in LTE system. D2D UEs send Msg1 to another D2D UE, and the recipient respond with Msg2. After the negotiation between D2D UEs, Msg3 and Msg4 are exchanged between UEs and eNB. Several embodiments are provided for the signaling of Msg3 and Msg4. The D2D data transmission may be enabled after the Msg4 or explicit data session initialization.

  • Publication number: 20120033613
    Abstract: An adaptive RACH operation is proposed for machine-type communications (MTC) in a 3GPP wireless network. The adaptive RACH operation is based on context information to reduce RACH collision probability, to control network overload, and to enhance system performance. The context information includes device related information and network related information. Device related information includes device type and service or application type. Network related information includes network load information and historical statistics information. Based on the context information, an MTC device adjusts various network access and RACH parameters by applying adaptive RACH operation in different levels. For example, in the application level and the network level, the MTC device adjusts its access probability or RACH backoff time for RACH access.

  • Publication number: 20100069083
    Abstract: Burst quality of service (QoS) mode uses a higher modulation rate and coding scheme for transmitting data blocks in a short period of time between a transmitting terminal and a user terminal experiencing a channel state above a certain threshold in a wireless communication system. Burst QoS may reduce data transmission time, thereby achieving a higher level of channel efficiency as well as a reduction in the consumption of power. In burst QoS mode, the channel state information (CSI) may be repeatedly measured. When the CSI is above a certain threshold, a higher rate modulation and coding (MC) scheme is used for burst data transmission. After the burst, a short sleep is triggered to reduce power consumption.
