Pusch frequency hopping enhancements

A wireless transmit/receive unit (WTRU) comprising:

• a receiver configured to:
• receive, from a network element, Physical Resource Block (PRB) exclusion information, the PRB exclusion information identifying PRBs excluded from a Physical Uplink Shared Channel (PUSCH) frequency hopping transmission;
• and
• receive, from the network element, a signal to trigger PUSCH frequency hopping transmission with PRB exclusion;
• a processor configured to;
• store the received the PRB exclusion information;
• and
• retrieve a most recently stored PRB exclusion information when the signal to trigger the PUSCH frequency hopping with PRB exclusion is received;
• and
• a transmitter configured to transmit a frequency hopping PUSCH signal with PRB exclusion according to the retrieved PBR exclusion information.

A method of triggering Physical Uplink Shared Channel (PUSCH) frequency hopping transmission implemented by a network element, the method comprising:

• identifying an interference signal;
• determining the interference signal is equal to or greater than a threshold value;
• determining one or more wireless transmit/receive units (WTRUs) capable of incurring the interference signal at a level equal to or greater than the threshold value;
• generating Physical Resource Block (PRB) exclusion information, the PRB exclusion information identifying PRBs excluded from the PUSCH frequency hopping transmission;
• and
• transmitting a signal to trigger the PUSCH frequency hopping transmission with PRB exclusion.
