摘要： One out of sixteen preamble signatures is selected. A code is produced based on the selected preamble signature. The produced code is phase rotated to produce a processed preamble signature signal. The processed preamble signature signal is used in processing the CDMA RACH signal and the CDMA RACH signal is used to access a CDMA system.

摘要： A circuit for use in a receiver receives a plurality of code division multiple access data signals simultaneously. Each data signal experiences a similar channel response. The circuit receives a combined signal over the shared spectrum in a time slot. The combined signal comprises the plurality of data signals. The combined signal is sampled at a multiple of a chip rate of the combined signal. The similar channel response is estimated. A channel response matrix or a channel correlation matrix is constructed based in part on the estimated channel response. A spread data vector is determined based in part on a fast Fourier transform (FFT) decomposition of a circulant version of the channel response matrix or channel correlation matrix. The spread data vector is despread to recover data from the matrix.

摘要： K data signals are transmitted over a shared spectrum in a code division multiple access communication system. A combined signal is received and sampled over the shared spectrum. The combined signal has the K transmitted data signals. A combined channel response matrix is produced using the codes and impulse responses of the K transmitted data signals. A block column of a combined channel correlation matrix is determined using the combined channel response matrix. Each block entry of the block column is a K by K matrix. At each frequency point k, a K by K matrix &Lgr;(k) is determined by taking the fourier transform of the block entries of the block column. An inverse of &Lgr;(k) is multiplied to a result of the fourier transform. Alternately, forward and backward substitution can be used to solve the system. An inverse fourier transform is used to recover the data from the K data signals.

摘要： Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.
摘要翻译：在无线通信网络中分割数据。数据可以被拆分为使用多个基站来传输到用户设备，以便如果UE处于小区边缘，则可以改善带宽，或者可以由用户设备拆分以传输到多个基站，以便改善切换。数据分割可以在分组数据收敛协议层，无线电链路控制层或用户设备或基站上的媒体访问控制层执行。为了减少X2接口负载或延迟载波聚合，数据可以替代地分成网络节点，例如在服务网关中。

摘要： Methods and systems are disclosed facilitate differentiated QoS service for packets within a single packet stream. For example, extended QCI values may be used to differentiate service of video packets associated with different priorities. A flexible representation of QoS requirements/parameters is disclosed where QoS may be defined as a hyperspace that is a function of base QoS parameters. A WTRU may explicitly specify and/or request desired QoS parameters. A WTRU may be configured to perform one or more of video packet separation into a plurality of video packet sub-streams, merging of the video packet sub-streams, and/or reordering of the packets included in the video packet sub-streams. Techniques may be utilized to exposing more information to a data transmission network regarding the type of video packets (and/or other packets) being transmitted.

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.

摘要： The present invention is a receiver which includes a blind code detection device for determining the identity of a plurality of channels over which information is to be transmitted when the identity of all channels is not known by the receiver. The blind code detection device generates a candidate channel list filled with the identify of selected channels out of the plurality of channels. A multi-user detection device, responsive to the blind code detection device, processes those channels in the candidate code list.
