Abstract: A method and apparatus for a wireless receiver are described herein. A user equipment (UE) may process control information in a first time slot of a transmission time interval (TTI) having a plurality of time slots. The UE may, in response to the control information including valid resource assignment information for the UE, receive data in the first time slot and another time slot of the TTI. The UE may, in response to the control information not including valid resource assignment information for the UE, discontinue reception in the TTI. The UE may discontinue reception for another time slot of the TTI. The circuitry may be further configured to receive a transmission indicating that a base station will discontinuously transmit to the UE. The control information may be processed prior to processing any of the data symbols of the TTI.

Abstract: Methods and apparatus are described for providing compatible mapping for backhaul control channels, frequency first mapping of control channel elements (CCEs) to avoid relay-physical control format indicator channel (R-PCFICH) and a tree based relay resource allocation to minimize the resource allocation map bits. Methods and apparatus (e.g., relay node (RN)/evolved Node-B (eNB)) for mapping of the Un downlink (DL) control signals, Un DL positive acknowledgement (ACK)/negative acknowledgement (NACK), and/or relay-physical downlink control channel (R-PDCCH) (or similar) in the eNB to RN (Un interface) DL direction are described. This includes time/frequency mapping of above-mentioned control signals into resource blocks (RBs) of multimedia broadcast multicast services (MBMS) single frequency network (MBSFN)-reserved sub-frames in the RN cell and encoding procedures for these. Also described are methods and apparatus for optimizing signaling overheads by avoiding R-PCFICH and minimizing bits needs for resource allocation.

Abstract: A system and a method of controlling transmitter power in a wireless communication system in which user data is processed as a multirate signal in which the user data signal having a first rate is converted into a transmission data signal having a faster second rate for transmission. The transmission power is adjusted on a relatively slow basis based on quality of data received by a receiver of the transmitted data. The transmitter power is determined as a function of the first and second rates such that a change in the data rate in the multiple channels or the rate of the transmission data signal is compensated in advance of a quality of data based adjustment associated with such data rate change.

Abstract: A method for determining the validity of a most significant path in a wireless communication system wherein data is transmitted in frame units in a multipath environment begins by accumulating a correlated data sequence N times, each time at a frame offset apart from the previous time. A preliminary noise estimate (PNE) is calculated as an average of the accumulated data values. A preliminary noise threshold (PNT) is calculated according to the equation C1×PNE. A final noise estimate (FNE) is calculated as the average of accumulated data values below the PNT. A final noise threshold (FNT) is calculated according to the equation C2×FNE. The validity of the most significant path is determined if the most significant path value is greater than the FNT.
