摘要： User Equipment (UE) transmits an acknowledgement signal in response to the reception of multiple Scheduling Assignments (SAs) transmitted by a base station. The SAs consist of Information Elements (IEs) including a Transmission Power Control (TPC) IE providing adjustments for the transmission power of the acknowledgement signal. The TPC IE in a first SA of the multiple SAs is used to provide the previous adjustments and the TPC IEs in the remaining of the multiple SAs are used to provide an indication of the resource used for the transmission of the acknowledgment signal.

摘要： Methods and apparatus are provided for a User Equipment (UE) configured to have multiple cells in a DownLink (DL) of a Time Division Duplex (TDD) communication system so as to determine a power of an acknowledgement signal that the UE transmits in a control channel and to determine a number of acknowledgement information bits that the UE multiplexes with data information bits in a data channel. A transmission power of the control signal is determined based on DL Assignment Index (DAI) Information Elements (IEs) in DL Scheduling Assignments (SAs) that the UE detects through multiple transmission time intervals and through the multiple configured DL cells. The number of acknowledgement information bits in the data channel is determined based on a DAI IE of an UpLink (UL) SA associated with the transmission of the data channel.

摘要： A method and apparatus for transmitting/receiving pilot symbols for demodulation of control channel information in the uplink of a wireless communication system are provided. When an Evolved Node B (ENB) expects to receive both the Channel Quality Information (CQI) and the Acknowledgement (ACK)/Negative ACK (NACK) from a User Equipment (UE) in a certain subframe, if the UE transmits only the CQI channel, the ENB is prevented to detect the nonexistent ACK/NACK information from the CQI channel, thereby avoiding false alarm.

摘要： A system and method for performing Scheduling Assignments (SAs) for User Equipments (UEs) at a base station of a communication system by accounting for the different operating conditions UEs may experience or for the different data rates or data packet sizes UEs may require. This reduces a total size of SAs by introducing compact SAs, in addition to full SAs. For compact SAs, the range for the resource allocation or for the spectral efficiency of the signal transmission is restricted or some fields that exist in the full SA are eliminated without adversely impacting scheduling flexibility or system throughput. By reducing the total size of SAs through the use of compact SAs, the corresponding control signaling overhead is reduced, which improves system throughput, improves scheduling flexibility, or improves coverage.

摘要： Methods and apparatus for transmitting and receiving Downlink Control Information (DCI) in a single cell in order to support communication over multiple cells. The DCI is conveyed by DCI formats transmitted through Physical Downlink Control CHannels (PDCCHs) in a UE-Common Search Space (UE-CSS) and in a UE-Dedicated Search Space (UE-DSS). A distinct UE-DSS is defined in the single cell for each of the multiple cells. Each distinct UE-DSS has the same structure as a conventional UE-DSS and a location that is determined by the same parameters as the location of the conventional UE-DSS and by the respective cell identity (Cell_ID).

摘要： Methods and apparatuses are described for a Node B to transmit Reference Signals (RS) from multiple antennas to enable User Equipments (UEs) to perform demodulation of received information signals and to estimate Channel Quality Indication (CQI) metrics. To minimize overhead and enable backward compatible operation with legacy systems, RS from a first set of Node B antennas are transmitted in every transmission time interval and substantially over the whole operating BandWidth (BW). RS from a second set of Node B antennas serving for CQI estimation are periodically transmitted, substantially over the whole operating BW, with transmission period informed to UEs through broadcast signaling by the Node B and starting transmission sub-frame determined from the identity of the cell served by the Node B. RS from the second set of antennas, and new RS from the first set of antennas, serving for demodulation of information signals have substantially the same BW as the information signals which can be smaller than the operating BW.
