摘要： A transmission of information within a wireless cellular network may include a first and second type of information. A subframe is produced that includes a plurality of symbols, wherein at least one symbol is designated as a data symbol and at least one symbol is designated as a reference signal symbol that contains a pre-defined reference signal. The first type of information is embedded in the data symbols. If the second type of data is expected, then the second type of information is embedded in at least one reference symbol by quadrature amplitude modulating the pre-defined reference signal. The subframe is then transmitted from one node in the network to a second node. In some embodiments, if it is determined that the second node is not expecting the second type of information, then a discontinuous transmission (DTX) response is embedded in the reference symbol instead of the second type of information.

摘要： A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed. Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.

摘要： This invention extends the coverage and improves the capacity of wireless communication networks using relay nodes. The relay nodes are wirelessly connected to the base station. The base station uses the same radio access technology for a link between the base station and user equipment and between the base station and the relay node. The relay node uses the same radio access technology for a link between the base station and the relay node and between the relay node and the user equipment. The relay node supports at least a Physical Layer (PHY), a Medium Access Control (MAC) sub-layer and a Radio Link Control (RLC) sub-layer protocol.

摘要： Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. One or more priority symbols are generated using the digital samples of the priority information. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. For example, Rank Indicator (RI) is transmitted using symbol k, ACKNAK is transmitted using symbol k+1; and the reference signal (RS) is transmitted using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time. The other symbols are transmitted in available locations.

摘要： A transmitter is for use with multiple transmit antennas and includes a precoder unit configured to precode data for a transmission using a precoding matrix selected from a codebook, wherein the codebook corresponds to the following three transmission properties for an uplink transmission: 1) all precoding elements from the precoding matrix have a same magnitude, 2) each precoding element from the precoding matrix is taken from a set of finite values and 3) there is only one non-zero element in any row of the precoding matrix. The transmitter also includes a transmit unit configured to transmit the precoded data.

摘要： This invention is applicable to wireless communication between a user equipment (UE) and a base station using frames where at least one uplink (UL) is assigned a subframe to respond to a plurality of DL assigned subframes. This invention is an improvement in the acknowledge (ACK) or non-acknowledge (NAK) response by the UE. The UE generates an ACK or NAK dependent upon whether a DL communication is correctly received. For an UL subframe assigned to respond to communications on plural DL subframes, the UE logically combines plural ACK/NAK responses into a single bundled response for transmission to the base station. This logical combining produces a bit in a first digital state if all said responses are ACKs and in a second opposite digital state if any response is a NAK.
摘要翻译： 本发明可应用于使用其中至少一个上行链路（UL）被分配了子帧以响应多个DL分配子帧的帧的用户设备（UE）和基站之间的无线通信。 本发明是对UE的确认（ACK）或非确认（NAK）响应的改进。 UE根据是否正确接收到DL通信产生ACK或NAK。 对于分配用于响应多个DL子帧上的通信的UL子帧，UE将多个ACK / NAK响应逻辑地组合成单个捆绑响应以便传输到基站。 如果所有所述响应都是ACK，则该逻辑组合产生处于第一数字状态的位，并且如果任何响应是NAK，则产生第二相反数字状态。
