Abstract
Aspects of the present application provide methods and devices in a communication network that aid in implementing sounding reference signal (SRS) measurement by multiple cells (i.e. serving cells and non-serving cells, also known as “neighbor cells”) as well as NR LMUs. This enhanced SRS measurement based on multiple cell and/or NR LMU measurements may facilitate more beneficial usages such as UL-based positioning and UL-based mobility.
Claims28
A method comprising:
- receiving, by a user equipment (UE), downlink (DL) reference signal (RS) configuration information from a serving cell network device, the DL RS configuration information associated with the serving cell network device or a non-serving cell network device, for configuring the UE to receive a DL RS from the non-serving cell network device;
- receiving, by the UE, the DL RS from the non-serving cell network device;
- and
- transmitting, by the UE, a sounding reference signal (SRS), the SRS transmitted in accordance with a transmission parameter based on the received DL RS.
1 more element
A user equipment (UE) comprising:
- a processor;
- a computer-readable storage medium having stored thereon, computer-executable instructions that when executed by the processor cause the UE to:
- receive, by the UE, downlink (DL) reference signal (RS) configuration information from a serving cell network device, the DL RS configuration information associated with the serving cell network device or a non-serving cell network device, for configuring the UE to receive a DL RS from the non-serving cell network device;
- receive, by the UE, the DL RS from the non-serving cell network device;
- and
- transmit, by the UE, a sounding reference signal (SRS), the SRS transmitted in accordance with a transmission parameter based on the received DL RS.
3 more elements
A method comprising:
- in response to a user equipment (UE) failing to detect a first SS/PBCH block configured to the UE for pathloss estimation, receiving, by the UE, a second SS/PBCH block from a serving cell network device, the second SS/PBCH used for obtaining a Master Information Block (MIB);
- estimating, by the UE, the pathloss from the second SS/PBCH block;
- and
- transmitting, by the UE, a sounding reference signal (SRS) to at least one of the serving cell network device or a non-serving cell network device using a transmit power based on the estimated pathloss.
