摘要： PROBLEM TO BE SOLVED: To provide a technique for more efficiently transmitting pilot and signaling on the uplink in a wireless communication system. SOLUTION: There is provided the technique for more efficiently transmitting the pilot and signaling on the uplink in an OFDM system. With subband multiplexing, M usable subbands in the system are partitioned into Q disjoint groups of subbands. Each subband group may be assigned to a different terminal for uplink pilot transmission. Multiple terminals may transmit simultaneously on their assigned subbands. The transmit power for the pilot may be scaled higher to attain the same total pilot energy even though S instead of M subbands are used for pilot transmission by each terminal. Pilot transmissions from the terminals are received, and a channel estimate is derived by each terminal. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide techniques with which the frequency response of a wireless channel in an OFDM system is estimated.
SOLUTION: In one method, an initial estimate of the frequency response of the wireless channel is obtained for a first group of subbands on the basis of a pilot transmission received via the subbands in the first group. An estimate of the impulse response of the wireless channel is then derived on the basis of the initial frequency response estimate. An enhanced estimate of the frequency response of the wireless channel is then derived for a second group of subbands on the basis of the impulse response estimate. The first and the second groups may each include all or only a subset of the usable subbands. Subband multiplexing may be used to allow simultaneous pilot transmissions by multiple terminals on their associated groups of subbands.

摘要： PROBLEM TO BE SOLVED: To transmit a pilot and signaling more efficiently on the uplink in a wireless communication system.SOLUTION: With subband multiplexing, M usable subbands in a system are partitioned into Q disjoint groups included in only one group. Each subband group is then assigned to a different terminal. Multiple terminals transmit simultaneously on their assigned subbands. For each terminal, transmit power for a pilot in each subband is set higher so that the same total pilot energy is achieved even though the pilot transmission is over S instead of M subbands. A channel estimate is derived for each terminal on the basis of the pilot received on the subbands assigned to the terminal. The channel estimate for each terminal covers one or more additional subbands. The subband multiplexing is also used for the uplink signaling transmission.
