摘要:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting channel state information, wherein the method comprises the steps of: receiving configuration information for a period report of CSI from a first transmission point; and transmitting, to said first transmission point, a CSI report for the downlink of a transmission point corresponding to a corresponding subframe among a plurality of transmission points through each subframe that is periodically set according to said configuration information, wherein: one or more subframes corresponding to a second transmission point are used to transmit a CSI report for multi-transmission point cooperative transmission, if rank information reported to said first transmission point prior to said CSI report is a critical value or less; and one or more subframes corresponding to said second transmission point are used to transmit a CSI report for single-transmission point transmission, if the rank information reported to said first transmission point prior to said CSI report is said critical value or more.

The present invention relates to a method for enabling a terminal to report channel state information in a wireless communication system for supporting coordinated multi point (CoMP) transmission. Specifically, the method for enabling the terminal to report the channel state information in the wireless communication system for supporting CoMP transmission includes the steps of: receiving a reference signal from a serving cell and one or more cooperated cells; forming the channel state information for the CoMP transmission on the basis of the reference signal; and reporting the channel state information through a physical uplink shared channel to the serving cell, wherein the channel state information includes channel quality indicator (CQI) information and precoding matrix index (PMI) information, and the CQI information includes a wideband CQI and a CQI for each selected sub-band of the CoMP transmission.

摘要:
A wireless device receives one or more messages including configuration parameters, for transmission configuration indicator (TCI) indication, of a first control resource set (coreset) and a second coreset. The wireless device receives, via the first coreset and based on a first TCI state, a first control command indicating a second TCI state. In response to the receiving the first control command: downlink transport blocks are received via a downlink shared channel and based on the second TCI state, a first downlink control channel is received via the first coreset and based on the first TCI state; and a second downlink control channel is received via the second coreset and based on the second TCI state.

Described are embodiments for selecting a preamble for a random access procedure. In an embodiment, a wireless device receives one or more configuration parameters of physical random access channel (PRACH) occasions for the random access procedure. One or more PRACH occasions of the PRACH occasions correspond to a respective RS of a plurality of RSs. The wireless device determines a RS, from the plurality of RSs, based on a reference signal received power (RSRP) value of the RS, and a transmission power reduction value associated with the RS. The wireless device determines a PRACH occasion, associated with the RS, from the PRACH occasions. Then, the wireless device transmits, via the PRACH occasion, a preamble for the random access procedure.

A multi-cell electrochemical reaction cell structure for a flow battery or fuel cell having a plurality of cells electrically connected in series or parallel. A first housing has a pair of mating end plates assembled together, each forming a plurality of recesses in which one of the cells is received. One of the end plates has a projection along its perimeter and the other one of the end plates has a groove along its perimeter. The projection is configured to fit within the groove in a mating relationship to seal the housing when the end plates are engaged with each other. A second housing is a tubular shell in which a plurality of tubular flow cell units electrically connected in parallel are housed. Catholyte flows in the tubular flow cell units and anolyte flows in the tubular shell.
