Abstract: The present invention discloses a method, system and device for determining a bandwidth of an uplink sounding reference signal SRS. The method for determining the bandwidth of the uplink SRS comprises the following steps: determining whether SRS is transmitted with the uplink pilot time slot if the SRS is transmitted with the largest bandwidth level; transmitting SRS with the non-extensive SRS bandwidth if SRS is determined to be transmitted with the uplink pilot time slot and the UE reaches the power limit. In the present invention, the signal-to-noise ratio detected on the bandwidth with which SRS transmitted can be maintained, and the accurate detection of the channel information is thereby realized.

Abstract: An adaptive modulation and coding method includes selecting punctured Physical Resource Blocks (PRBs) to transmit downlink data for User Equipment (UE); determining Transport Block Size (TBS) and number of punctured PRB pairs for transmission to the UE based on the carried service; scheduling downlink data for the UE based on determined TBS, and transmitting the number of used punctured PRB pairs and a Modulation and Coding Scheme (MCS) sequence number to the UE; and the UE converting number of the punctured PRB pairs to number of normal PRB pairs, determining modulation scheme and TBS sequence number based on the MCS sequence number, and determining TBS of the downlink data based on number of normal PRB pairs and TBS sequence number.
