Abstract
Certain aspects of the present disclosure provide a method for wireless communication by a wireless device. The method generally includes selecting multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria. The multiple TRPs of the group of TRPs are selected such that levels of communication delay between each of the multiple TRPs and the UE are within a defined delay range. The method further includes communicating on an uplink using a single timing advance between the UE and the group of TRPs.
Claims27
A method of wireless communication by a wireless device, the method comprising:
- selecting multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria, wherein the information indicative of the relative positions comprises reference signal time difference measurements (RSTDs) between the UE and each of the plurality of TRPs, wherein a first TRP is selected for the group of TRPs based on the first TRP having a signal quality between the UE and the first TRP that satisfies a threshold, and wherein remaining TRPs of the multiple TRPs are selected to maximize a number of the plurality of TRPs that satisfy the criteria;
- and
- communicating on an uplink using a single timing advance between the UE and the group of TRPs.
A wireless device comprising:
- a memory;
- and
- a processor coupled to the memory, the processor and memory configured to:
- select multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria, wherein the information indicative of the relative positions comprises reference signal time difference measurements (RSTDs) between the UE and each of the plurality of TRPs, wherein the processor and memory are further configured to select a first TRP for the group of TRPs based on the first TRP having a signal quality between the UE and the first TRP that satisfies a threshold and to select remaining TRPs of the multiple TRPs to maximize a number of the plurality of TRPs that satisfy the criteria;
- and
- communicate on an uplink using a single timing advance between the UE and the group of TRPs.
A wireless device comprising:
- means for selecting multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria, wherein the information indicative of the relative positions comprises reference signal time difference measurements (RSTDs) between the UE and each of the plurality of TRPs, wherein a first TRP is selected for the group of TRPs based on the first TRP having a signal quality between the UE and the first TRP that satisfies a threshold, and wherein remaining TRPs of the multiple TRPs are selected to maximize a number of the plurality of TRPs that satisfy the criteria;
- and
- means for communicating on an uplink using a single timing advance between the UE and the group of TRPs.
A non-transitory computer-readable medium that comprises instructions that when executed by a wireless device, cause the wireless device to perform a method of wireless communication, the method comprising:
- selecting multiple transmission reception points (TRPs) of a plurality of TRPs to form a group of TRPs based on information indicative of relative positions between a user equipment (UE) and each of the plurality of TRPs such that the relative positions between the UE and the multiple TRPs satisfy a criteria, wherein the information indicative of the relative positions comprises reference signal time difference measurements (RSTDs) between the UE and each of the plurality of TRPs, wherein a first TRP is selected for the group of TRPs based on the first TRP having a signal quality between the UE and the first TRP that satisfies a threshold, and wherein remaining TRPs of the multiple TRPs are selected to maximize a number of the plurality of TRPs that satisfy the criteria;
- and
- communicating on an uplink using a single timing advance between the UE and the group of TRPs.
