Abstract

Claims (28)

1 . A wireless communication method, comprising:

receiving, by a reduced capability (RedCap) device from a wireless communication node, information associated with sounding reference signal (SRS) hopping, via a radio resource control (RRC) signaling,

wherein the RRC signaling includes frequency resource related information which indicates a start resource block (RB) number and a number of overlapped RB;

wherein the RRC signaling further includes time resource related information which indicates at least one of a periodicity or a slot offset for each hop; and

transmitting by the RedCap device, a SRS outside a configured bandwidth part (BWP).

2 . The wireless communication method of claim 1 , further comprising:

transmitting, by the RedCap device, the SRS in a SRS transmission window where no other signal is transmitted.

3 . The wireless communication method of claim 1 further comprising:

determining, by the RedCap device, to drop the SRS if the SRS collides with a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).

4 . A reduced capability (RedCap) device, comprising:

at least one processor configured to:

receive, via a transceiver from a wireless communication node, information associated with sounding reference signal (SRS) hopping, via a radio resource control (RRC) signaling,

wherein the RRC signaling includes frequency resource related information which indicates a start resource block (RB) number and a number of overlapped RB;

wherein the RRC signaling further includes time resource related information which indicates at least one of a periodicity or a slot offset for each hop; and

transmit, via the transceiver, a SRS outside a configured bandwidth part (BWP).

5 . The RedCap device of claim 4 , wherein the at least one processor is configured to:

transmit, via the transceiver, the SRS in a SRS transmission window where no other signal is transmitted.

6 . The RedCap device of claim 4 , wherein the at least one processor is configured to:

determine to drop the SRS if the SRS collides with a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).

7 . A wireless communication method, comprising:

sending, by a wireless communication node to a reduced capability (RedCap) device, information associated with sounding reference signal (SRS) hopping, via a radio resource control (RRC) signaling,

wherein the RRC signaling includes frequency resource related information which indicates a start resource block (RB) number and a number of overlapped RB;

wherein the RRC signaling further includes time resource related information which indicates at least one of a periodicity or a slot offset for each hop; and

receiving, by the wireless communication node from the RedCap device, a SRS outside a configured bandwidth part (BWP).

8 . The wireless communication method of claim 7 , further comprising:

receiving, by the wireless communication node from the RedCap device, the SRS in a SRS transmission window where no other signal is transmitted.

9 . A wireless communication node, comprising at least one processor configured to perform the method of claim 7 .

10 . A wireless communication node, comprising at least one processor configured to perform the method of claim 8 .
