    摘要: A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

    摘要: A user equipment (UE) for controlling transmission power levels in a system employing a spread spectrum time division duplex (TDD) technique having frames with timeslots for communication comprises a measuring device configured to receive, during a first time slot, a communication including a power level and measure the power level of the received communication and an interference power level. A pathloss estimation device determines a pathloss estimate and a long term pathloss estimate, based in part on the measured power level and the received power level. A quality measurement device determines a first quality factor, α, and a second quality factor, 1−α, of the pathloss estimate based in part on a number of timeslots, D, between the first and a second timeslot. A transmit power calculation device sets a transmission power level for transmission during the second timeslot.

    摘要: Data of a time transmission interval is to be transmitted in a wireless communication system. The wireless communication system uses adaptive modulation and coding and has automatic repeat request mechanism. A transmission time interval has a plurality of transport block sets. The transport block sets are transmitted with a first specified modulation and coding scheme. Each transport block set is received and a determination is made as to whether the transport block sets meet a specified quality. When the specified quality is not met, a repeat request is transmitted. The specified modulation and coding scheme is changed to a second specified modulation and coding scheme that may support a reduced number of TBS's within the transmission time interval. In response to the repeat request, at least one of the transport block sets is retransmitted. The retransmitted transport block set is received. The retransmitted transport block set may be combined with a corresponding previously received transport block set.

The first specified modulation and coding set is changed to a second specified modulation and coding set. In response to the repeat request, the transmit block set is segmented into a plurality of segments supported by the second specified modulation and coding set in accordance with the provided segmentation information. The segments are transmitted and at least two of the segments are transmitted separately. The transmitted segments are received. The segmentation process may be applied more than once for a particular TBS transmission.

    摘要: A user equipment comprises a transmitter and an adaptive modulation and coding controller. The transmitter is configured to transmit data over an air interface in a single transmission time interval with a first specified modulation and coding scheme, where the single transmission time interval has a plurality of transport block sets. In response to receiving a repeat request for retransmission of at least one particular transport block set, the transmitter retransmits the at least one of the particular transport block sets. The adaptive modulation and coding controller is configured to change the specified modulation and coding scheme to a second specified modulation and coding scheme, enabling a combining of a particular transport block set transmitted at the first specified modulation and coding scheme with a retransmitted version of the particular transport block set transmitted at the second specified modulation and coding scheme.
