Abstract
Techniques described herein describe aspects of signal adjustments in user equipment-coordination set, UECS, joint transmissions. A base station analyzes a first joint transmission from multiple user equipments, UEs, participating in a UECS, where the multiple UEs include a coordinating UE of the UECS and at least one non-coordinating UE participating in the UECS. The base station determines that the first joint transmission fails to meet a performance metric and directs the multiple UEs participating in the UECS to add signal adjustments to a second joint transmission.
Claims20
A method performed by a base station for mitigating signal degradation in joint transmissions from a user equipment-coordination set (UECS) that includes multiple user equipments (UEs) the method comprising:
- analyzing a first joint transmission from multiple UEs in the UECS;
- determining the first joint transmission fails to meet a performance metric;
- and
- directing the multiple UEs participating in the UECS to add signal adjustments to a second joint transmission, the directing comprising directing the multiple UEs in the UECS to add random signal adjustments to their respective uplink signals.
A method performed by a coordinating user equipment (UE) of a user equipment-coordination set (UECS) for mitigating signal degradation in joint transmissions, the method comprising:
- coordinating a first joint transmission of a first uplink signal from the UECS to a base station;
- receiving, from the base station, a command to add signal adjustments to a second joint transmission to the base station, the command comprising a direction to add random signal adjustments to respective uplink signals of one or more UEs in the UECS;
- and
- directing one or more of the UEs in the UECS to add a respective signal adjustment to a respective uplink signal transmitted by the UE as part of a second joint transmission to the base station.
A method performed by a non-coordinating user equipment (UE) in a user equipment-coordination set (UECS) for mitigating signal degradation in joint transmissions, the method comprising:
- transmitting a first uplink signal as part of a first joint transmission to a base station;
- receiving, from a coordinating UE participating in the UECS, a command to add a signal adjustment in a second joint transmission to the base station, the command comprising a direction to add a random signal adjustment to a respective uplink signal of the non-coordinating UE;
- and
- transmitting a second uplink signal as part of a second joint transmission to the base station by adding the random signal adjustment to the second uplink signal.
An apparatus comprising:
- a processor;
- and
- computer-readable storage media comprising instructions, responsive to execution by the processor, for directing the apparatus to:
- analyze a first joint transmission from multiple user equipments (UEs) in a user equipment-coordination set (UECS);
- determine the first joint transmission fails to meet a performance metric;
- and
- direct the multiple UEs participating in the UECS to add signal adjustments to a second joint transmission, the direction comprising directing the multiple UEs in the UECS to add random signal adjustments to their respective uplink signals.
