Abstract: A method and apparatus for performing signal-to-interference ratio (SIR) estimation in wireless communications, using a demodulator output, such as a Rake output or a multi-user detection (MUD) receiver output. The demodulator output is fed into a SIR estimator to perform the SIR estimation based on estimated average signal power and estimated average effective interference power. The estimated average signal power is based on a minimum value function used for determining a minimum value between a median based average power value and a mean based average power value. The SIR estimator reduces bias effects on SIR estimation, and is applicable to BPSK and QPSK modulation schemes, as well as higher order modulation schemes such as 8-PSK and 16-QAM. A correction term is used as a function of the mean and median values to further mitigate the bias effect.

The produced sequences for different user identification codes have a high separation. A base station uses the UEIDSS to scramble a high speed shared control channel (HSSSCH) and a user equipment (UE) uses the UEIDSS to descramble the HSSSCH. The embodiments utilize various blocks for producing the codes. These blocks include Reed-Muller encoding (22), concatenation (24), rate matching (26), segmentation (20), convolutional encoding (44); tail bit discarding (46), zero padding (76), repeating (74), CRC calculation (62), quadratic residue coding (78), parity-check bit (80), shortening (82), puncturing (40) and BCH encoding blocks (86).

Abstract: An ACK/NACK method and system for use in time division duplex (TDD) and frequency division duplex (FDD) systems. In high speed downlink packet access (HSDPA), based on the assignment of timeslots for the high speed shared information channel (HS-SICH), each user equipment (UE) can be assigned two (2) different channelization codes. It is then possible to adopt the signaling convention that one code represents acknowledge error-free (Ack) and the other code shall represent acknowledge error condition (Nack). The Node B is able to distinguish the presence of the transmitted channelization code as opposed to the channelization code which is not transmitted. The probability of error, using this invention, is an order of a magnitude smaller than if the Ack/Nack were signaled using typical modulation techniques.

Abstract: In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.

Abstract: A wireless communication method and apparatus for decoding an enhanced uplink dedicated channel (E-DCH) absolute grant channel (E-AGCH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-AGCH data which includes a cyclic redundancy check (CRC) part and a data part. The CRC part is masked with a WTRU identity (ID) at a Node-B. The CRC part and the data part are demultiplexed and the CRC part is demasked with the WTRU ID. A CRC is then performed with the demasked CRC part. If the CRC passes the data part is sent to an enhanced uplink medium access control (MAC-e) entity. The WTRU ID may be a primary E-DCH radio network temporary identity (E-RNTI) or a secondary E-RNTI. When the E-AGCH data is transmitted over a 10ms frame, if the CRC fails, E-AGCH data via subsequent subframe may be soft combined with the previous E-AGCH data.

Abstract: A method, components and a system are provided for implementing power control for wireless communication transmissions that provides, inter alia, a remedy for the mismatch of initial transmission power (312) for NRT data by estimating a bias error (324) based and adjusting the transmission power by a compensation amount for an averaged bias error estimation (323) over all data set transmissions, such as sequential Temp-DCH allocations in a UMTS system. An alternative approach for a UMTS system estimates the bias error at a RNC based on an averaged transmit code power measurement by a base station (310) and applies a bias error compensation to the initial DL transmit power at the RNC.
