Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

Abstract: It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.
Abstract translation: 即使在传播路径中引起延迟，导致发送定时误差，或者在不同ZC序列的循环移位量之间产生残留干扰，也可以提高CQI接收性能。 对于由CQI的RS复用的ACK / NACK信号的第二符号和第六符号，（+，+）或（ - ， - ）被应用于沃尔什序列的部分序列。 对于从移动站发送的CQI的RS，将+作为第二符号的RS相位相加，并且作为第六符号的RS相加。 基站（100）接收从多个移动台发送的ACK / NACK信号和CQI信号的复用信号。 RS合成单元（119）通过对齐CQI的RS相位进行合成。

Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

Abstract: Systems, methods, and instrumentalities for a WTRU to perform channel estimation and/or noise estimation are provided. The techniques described herein may be used to perform channel estimation and/or noise estimation that meet certain performance and latency goals while utilizing a lower cost design than previous channel/noise estimation techniques. For example, the channel estimation/noise estimation techniques described herein may be implemented using less memory (e.g., less memory for storing filter coefficients) while still achieving the desired latency and performance goals. The techniques described herein may be implemented by any WTRU and/or by a WTRU specifically designed to be low-cost.

Abstract: A method for transmitting channel status information (CSI) via uplink in a wireless communication system includes transmitting a first precoding matrix indicator (PMI) and a second PMI at a subframe. A subsampled codebook for each of a precoding codebook for Rank-1 and a precoding codebook for Rank-2 is determined based on at least the first PMI or the second PMI. In case of the Rank-1 or the Rank-2, a number of elements for the first PMI is 8.
