TRANSMISSION OF SOUNDING REFERENCE SIGNALS FROM A USER EQUIPMENT IN RESPONSE TO MULTIPLE REQUESTS
First Claim
1. A method for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS), the method comprising the steps of:
- receiving a first Downlink Control Information (DCI) format with an aperiodic SRS request field indicating aperiodic SRS transmission with first values for aperiodic SRS transmission parameters;
receiving a second DCI format with an aperiodic SRS request field indicating aperiodic SRS transmission with second values for the aperiodic SRS transmission parameters;
comparing the first values for the aperiodic SRS transmission parameters with the second values for the aperiodic SRS transmission parameters; and
transmitting an aperiodic SRS when the first values are identical to the second values; and
suspending transmission of the aperiodic SRS when the first values are not identical to the second values.

Abstract
Methods and apparatus are provided for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS). A first Downlink Control Information (DCI) format with an aperiodic SRS request field indicating aperiodic SRS transmission with first values for aperiodic SRS transmission parameters, is received. A second DCI format with an aperiodic SRS request field indicating aperiodic SRS transmission with second values for the aperiodic SRS transmission parameters, is received. The first values for the aperiodic SRS transmission parameters are compared with the second values for the aperiodic SRS transmission parameters. An aperiodic SRS is transmitted when the first values are identical to the second values. Transmission of the aperiodic SRS is suspended when the first values are not identical to the second values.

5. A method for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS), the method comprising the steps of:
-
receiving a first number of Downlink Control Information (DCI) formats and a second number of DCI formats, wherein each of the first number of DCI formats conveys an aperiodic SRS request field indicating aperiodic SRS transmission and values for aperiodic SRS transmission parameters, and wherein each of the second number of DCI formats conveys an aperiodic SRS request field indicating no aperiodic SRS transmission; comparing the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats; disregarding the aperiodic SRS request field in each of the second number of DCI formats; transmitting an aperiodic SRS, when all of the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats are identical; and suspending transmission of the aperiodic SRS, when all of the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats are not identical. - View Dependent Claims (6, 7, 8)

13. A User Equipment (UE) apparatus for transmitting a Sounding Reference Signal (SRS), the UE apparatus comprising:
-
a receiver for receiving a first number of Downlink Control Information (DCI) formats and a second number of DCI formats, wherein each of the first number of DCI formats conveys an aperiodic SRS request field indicating aperiodic SRS transmission and values for aperiodic SRS transmission parameters, and wherein each of the second number of DCI formats conveys an aperiodic SRS request field indicating no aperiodic SRS transmission; a comparator for comparing the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats, and disregarding the aperiodic SRS request field in each of the second number of DCI formats; and a transmitter for transmitting an aperiodic SRS when all of the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats are identical, and suspending transmission of the aperiodic SRS when all of the values for the aperiodic SRS transmission parameters indicated by the aperiodic SRS request fields of each of the first number of DCI formats are not identical. - View Dependent Claims (14, 15, 16)
