Abstract
A method and apparatus for determining power, in which whether to increase target received power is determined according to a change of either of a selected SSB and a selected CSI-RS. Hence, the selected CSI-RS is taken into account, and power is increased as necessary and useless retransmission is avoided, thereby increasing the success rate of random access and reducing power consumption of the UE.
Claims18
An apparatus for determining power, comprising:
- a memory that stores a plurality of instructions;
- a processor that couples to the memory and is configured to execute the instructions to:
- select either a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) and determine whether to increase target received power according to a change of either of the selected SSB and the selected CSI-RS, wherein,
- the selected CSI-RS is used for determining the random access resource, and the change of either of the selected SSB and the selected CSI-RS at least comprises, a second CSI-RS is selected for a last Random Access Preamble transmission;
- or a second SSB is selected for a last Random Access Preamble transmission;
- or
- the selected SSB is used for determining the random access resource, and the change of either of the selected SSB and the selected CSI-RS at least comprises, a third CSI-RS is selected for a last Random Access Preamble transmission;
- the target received power is used for determining transmitting power of a random access preamble.

An apparatus for determining power, comprising:
- a memory that stores a plurality of instructions;
- a processor that couples to the memory and is configured to execute the instructions to:
- configure UE with a counter related to power ramping commonly used by a synchronization signal block (SSB) and a channel state information reference signal (CSI-RS);
- wherein the processor is further configured to:
- configure the UE with a rule that whether a quasi co-location relationship between the CSI-RS and the SSB is taken into account in determining whether a selected CSI-RS is changed, and/or configure the UE with a rule for determining whether a selected CSI-RS is changed when the quasi co-location relationship between the CSI-RS and the SSB is taken into account and/or the quasi co-location relationship between the CSI-RS and the SSB.
