摘要： This invention measures the propagation delay τ1 between the user equipment and a first cooperating unit and the propagation delay τ2 between the user equipment and a second cooperating unit. These propagation delays are used to compute a timing advance amount to the user equipment to enable coordinated multi-point reception. In a first embodiment one cooperating unit receives a function of the propagation delay, computes the timing advance amount and transmits a timing advance command to the user equipment. In a second embodiment a central unit performs these operations.

摘要： A transmission of information between a secondary to a primary node in a wireless network occurs in a plurality of N logical time durations. Bundled feedback information for multiple DL transmissions is provided in one UL transmission. Each DL transmission is indicated by a DL grant comprising an M-bit downlink assignment indicator (DAI) field. The primary node increments the value of the M-bit DAI field in successively transmitted DL grants. The secondary node examines the value of the M-bit DAI field in received DL grants, to determine the bundled feedback information.

摘要： This invention is a transmission scheme for multi-ACK/NAK and SRI in TDD. The described scheme enables using DAI as pure counter. QPSK is adopted as the modulation scheme in this invention which guarantees satisfactory detection performance. Link level simulations show that the event of one DL grant pass followed by three consecutive DL grant misses is of low probability.

摘要： ACK/NAK repetition may be necessary to provide sufficient coverage for cell edge UEs. For a coverage limited UE, a NodeB may inform the UE that ACK/NAK repetition is needed. Such information can be explicitly signaled to the UE via DL control channels or conveyed through higher layer signaling. Further, a specific resource for ACK/NAK repetition and the number of repeated transmissions of ACK/NAK are further signaled to the UE.

摘要： Apparatus and methods for accessing a wireless telecommunications network by transmitting a random access signal. The random access signal includes a random access preamble signal selected from a set of random access preamble signals constructed by cyclically shift selected root CAZAC sequences. The random access signal may be one or more transmission sub-frames in duration, the included random access preamble sequence's length being extended with the signal to provide improved signal detection performance in larger cells and in higher interference environments. The random access signal may include a wide-band pilot signal facilitating base station estimation of up-link frequency response in some situations. Each of the plurality of available random access preamble sequences may be assigned a unique information value. The base station may use the information encoded in the random access preamble to prioritize responses and resource allocations. Random access signal collisions are dealt with by a combination of preamble code space randomness and back-off procedures.

摘要： A method is described for operating a cellular network, where the cellular network uses a plurality of frequency division multiplexing (FDM) bands for wireless communication from user equipment (UE) to a base station (NodeB). At least one band-specific cell parameter is computed for at least one the plurality of FDM bands by a serving NodeB. The band-specific cell parameters are transmitted from the NodeB serving a first cell to a NodeB serving a second cell. The band-specific cell parameters may be computed in response to scheduling information and/or channel specific measurements made by the NodeB. A UE receives a first Power Configuration, a Second Power Configuration, and a Scheduling Message indicative of an FDM band from the set comprising at least from First FDM band and Second FDM band. The UE transmits with the First Power Configuration if the Scheduling Message was indicative of First FDM band, and with the Second Power Configuration otherwise.
