Title:
共有周波数スペクトル帯域上のサウンディング基準信号の送信を管理するための技法
Document Type and Number:
Japanese Patent JP7198842
Kind Code:
B2
Abstract:
A network may use enhanced reference signal transmission techniques to support reference signal transmissions over shared spectrum. For example, a wireless device may identify an uplink transmission time period associated with an unlicensed radio frequency spectrum band, wherein said uplink transmission time period corresponds to a duration of an assigned physical uplink shared channel, PUSCH, transmission, or an assigned physical uplink control channel, PUCCH, transmission. Then, the wireless device may receive an indicator in a downlink transmission associated with an uplink transmission of a sounding reference signal, wherein the indicator alerts to transmit the sounding reference signal without designating a location of a sounding reference signal time period relative to the uplink transmission time period. Finally, the wireless device may transmit the sounding reference signal over the unlicensed radio frequency spectrum band according to a predetermined configuration, wherein the predetermined configuration includes the location of the sounding reference signal time period to be following the conclusion of the PUSCH/PUCCH assignment.
