摘要： Transmission of random access preamble structures within a cellular wireless network is based on the use of cyclic shifted constant amplitude zero autocorrelation ("CAZAC") sequences to generate the random access preamble signal. A pre-defined set of sequences is arranged in a specific order. Within the predefined set of sequences is an ordered group of sequences that is a proper subset of the pre-defined set of sequences. Within a given cell, up to 64 sequences may need to be signaled. In order to minimize the associated overhead due to signaling multiple sequences, only one logical index is transmitted by a base station serving the cell and a user equipment within the cell derives the subsequent indexes according to the pre-defined ordering. Each sequence has a unique logical index. The ordering of sequences is identified by the logical indexes of the sequences, with each logical index uniquely mapped to a generating index. When a UE needs to transmit, it produces (1410) a second sequence using the received indication of the logical index of the first sequence and an auxiliary value and then produces a transmission signal by modulating the second sequence. The auxiliary value is selected (1408) from one of two sets based on a set indicator broadcast (1404) by the eNB.

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 cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). UEs are synchronized to the eNB upon entry to the cell. If a particular UE has data to transmit, it will be placed in a connected state and scheduled for transmission. Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked (402) as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained (404) between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed in response to receiving a scheduled transmission from each respective UE in the scheduled portion; Synchronization is maintained (406) between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.

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 (100) 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： Transmission of sequences in wireless networks from a user equipment (UE) includes various types of reference signals, such as a sounding reference signal (SRS) and a physical uplink control channel (PUCCH) symbol. The UE receives (402) an indication of a reference signal sequence group number u , wherein physical uplink control channel (PUCCH) sequences are divided into groups having at least one sequence each and wherein sounding reference signal (SRS) sequences are divided into groups having at least one sequence each. The UE produces (414) a sequence from an SRS sequence group with the sequence group number u when an SRS is to be transmitted and produces (412) a sequence from a PUCCH sequence group with the sequence group number u when a PUCCH symbol is to be transmitted. The UE produces (416) a transmission signal using the produced sequence.

摘要： Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information (1304). Digital samples are produced using an element of prioritized information (1306). One or more priority symbols are generated using the digital samples (1308). Other symbols are generated using the other data (1310). Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. The other symbols are transmitted in available locations (1312).
