摘要： PROBLEM TO BE SOLVED: To provide techniques to more efficiently transmit pilots on demand on a reverse link.SOLUTION: Pilots are transmitted on demand on a reverse link and used for channel estimation and data transmission on a forward link. A base station selects at least one terminal for on-demand pilot transmission on the reverse link (210). Each of the at least one selected terminal is a candidate for receiving data transmission on the forward link. The base station assigns each of the at least one selected terminal with a time-frequency allocation (212), which may be for a wideband pilot, a narrowband pilot, or some other type of pilot. The base station receives and processes an on-demand pilot transmitted from each of the at least one selected terminal (216) and derives a channel estimate for the terminal based on the received pilot (218).

摘要： PROBLEM TO BE SOLVED: To provide a system and method for power control and scheduling of sub-carriers in an OFDM communication system.SOLUTION: A receiver dynamic range can be minimized by a power control loop that attempts to maintain received power over a noise floor in a predetermined range. If the received power relative to the noise floor in allocated sub-carriers exceeds the predetermined range and the total received power is at a minimum, a scheduling system allocates an additional sub-carrier to a communication link. Additionally, if the received power relative to the noise floor is less than the predetermined range minimum and the total received power is at a maximum, the scheduling system de-allocates the sub-carrier from the communication link. The scheduling system may also adjust an encoding rate to maintain a relatively constant symbol rate in each of the sub-carriers.
摘要翻译：要解决的问题：提供一种用于OFDM通信系统中的子载波的功率控制和调度的系统和方法。解决方案：可以通过功率控制回路来最小化接收机动态范围，该功率控制环路试图将接收到的功率保持在预定范围内的本底噪声。如果所分配的子载波中相对于本底噪声的接收功率超过预定范围并且总接收功率处于最小，则调度系统向通信链路分配附加子载波。此外，如果相对于本底噪声的接收功率小于预定范围最小值并且总接收功率处于最大值，则调度系统从通信链路去分配子载波。调度系统还可以调整编码速率以在每个子载波中维持相对恒定的符号率。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a quick paging channel with reduced probability of missed page.
SOLUTION: The quick paging channel in a random-connection radio communication system includes at least one bit in a quick paging frame, which can discriminate the existence of a paging message to an access terminal or an access terminal group. A quick paging bit to discriminate the existence of the paging message to the first access terminal is encoded together with one or more quick paging bits corresponding to one or more additional access terminals to constitute one or more forward error correction bit. The quick paging bit encoded at the same time is broadcast to a plurality of access terminals, by time-division multiplexing of the quick paging frame together with an additional information frame. Moreover, a paging block can be compressed.

摘要： PROBLEM TO BE SOLVED: To provide efficient pilot transmission system for multi-antenna communication systems. SOLUTION: In one pilot transmission system, a first set of T scaled pilot symbols is generated with a first training vector and transmitted (e.g., continuously) from T transmit antennas, where T>1. If MIMO receiver(s) are to be supported by the system, then at least T-1 additional sets of T scaled pilot symbols are generated with at least T-1 additional training vectors and transmitted from the T transmit antennas. The training vectors are for different (e.g., orthogonal) spatial directions. Each MISO receiver can estimate its MISO channel based on the first set of scaled pilot symbols. Each MIMO receiver can estimate its MIMO channel based on the first and additional sets of scaled pilot symbols. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for using different modulation schemes for retransmission of a packet. SOLUTION: A plurality of modulation schemes are used for a single packet, so that each data packet is processed and transmitted in up to T(T>1) blocks. The plurality of modulation schemes are used for the T blocks. A transmitter encodes a data packet to generate code bits. The transmitter then forms a block of code bits using the code bits generated for the packet, determines the modulation scheme to use for the block (e.g., based on a mode/rate), maps the code bits for the block based on the modulation scheme to obtain data symbols, and processes the block of data symbols and transmits the block to a receiver. The transmitter generates and transmits another block in similar manner until the data packet is decoded correctly or all T blocks have been transmitted. The receiver performs complementary processing to receive and decode the packet. COPYRIGHT: (C)2009,JPO&INPIT
