Abstract
Methods and apparatuses for power headroom report are disclosed. In one embodiment, a method comprises determining one or two PH values when power headroom report triggering condition is satisfied for a serving cell configured with two SRS resource sets used both for codebook based UL transmission or both for non-codebook based UL transmission; and transmitting the determined one or two PH values for the serving cell in one PHR MAC CE.
Claims31
A method of a user equipment (UE), comprising:
- determining one or two power headroom (PH) values when a power headroom report triggering condition is satisfied for a serving cell configured with two sounding reference signal (SRS) resource sets used both for codebook based uplink (UL) transmission or both for non-codebook based UL transmission;
- and
- transmitting the determined one or two PH values for the serving cell in one power headroom report (PHR) medium access control (MAC) control element (CE).

A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- determine one or two power headroom (PH) values when a power headroom report triggering condition is satisfied for a serving cell configured with two sounding reference signal (SRS) resource sets used both for codebook based uplink (UL) transmission or both for non-codebook based UL transmission;
- and
- transmit the determined one or two PH values for the serving cell in one power headroom report (PHR) medium access control (MAC) control element (CE).
A base station for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the base station to:
- receive one or two power headroom (PH) values for a serving cell configured with two sounding reference signal (SRS) resource sets used both for codebook based uplink (UL) transmission or both for non-codebook based UL transmission in one power headroom report (PHR) medium access control (MAC) control element (CE),
- wherein the one PHR MAC CE includes a bitmap with two bits, and each bit indicates a presence or absence of one PH value.
A processor for wireless communication, comprising:
- at least one controller coupled with at least one memory and configured to cause the processor to:
- determine one or two power headroom (PH) values when a power headroom report triggering condition is satisfied for a serving cell configured with two sounding reference signal (SRS) resource sets used both for codebook based uplink (UL) transmission or both for non-codebook based UL transmission;
- and
- transmit the determined one or two PH values for the serving cell in one power headroom report (PHR) medium access control (MAC) control element (CE).
