摘要： A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is obtained using a first and a second sequence. Embodiments of the present invention mitigate interference by restricting the choice of the first sequence. Thus, in an embodiment of the invention, the first sequence is selected from a set of M sequences wherein M is strictly less than N. In order to accommodate high-velocity users, the restricted set contains a pair of sequences whose element-wise product is mirror symmetric. In other embodiments of the invention, the choices of the first sequence and second sequence in a time-frequency resource is arranged such that interference is mitigated. A transmission component for K-th logical time duration is obtained from the entire second sequence and K-th element of the first sequence.

摘要： A method of transmitting signals in a communication system over at least two time periods including generating a base signal comprising of at least two samples in each time period, selecting a scrambling sequence of length equal to or greater than the number of time periods, scaling all samples in said signal in a time period with one element of said scrambling sequence and transmitting the scaled signal in said time period. Different elements of the scrambling sequence are used to scale the base signal in different time periods. The signal in each time period is obtained by scaling a base signal. The scrambling sequence is preferably a pseudo-random sequence. The step of scaling all samples in said signal in a time period consists of multiplying all samples of said signal with an element of said scrambling sequence.

摘要： This invention is a method for time-sharing sounding resources. This invention time-shares one sounding source across plural user equipment for different sub-frames. This invention uses different sounding periods which are periodic and either non-changing in time or changing in time. Different user equipment have sounding periodicities where one is an integral multiple of the other. This invention also allocates and updates a sub-frame offset for each user equipment.

摘要： A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).

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.
