Abstract
Methods and apparatus are provided. In an example aspect, a method in a first access point of transmitting a signal is provided. The method includes, for each of a plurality of User Equipments (UEs), determining a phase alignment correction factor (PACF) for the UE based on an access point group associated with the UE, and transmitting a respective first signal to the UE, wherein the first signal is phase adjusted using the PACF determined for the UE.
Claims22
A method in a first access point of transmitting a signal, the method comprising, for each of a plurality of User Equipments:
- obtaining multiple phase alignment correction factors for different access point groups, the first access point belonging to multiple access point groups, the PACF values differing for the different access point groups;
- determining an access point group associated with the UE from the plurality of access point groups, the first access point being in each of the access point groups;
- determining the PACF for the UE based on the access point group associated with the UE;
- and
- transmitting a respective first signal to the UE, the first signal being phase adjusted using the PACF determined for the UE.
(canceled)
A method in a network node of causing an access point to transmit a signal, the method comprising:
- determining access point groups for a plurality of access points, wherein at least one first access point of the plurality of access points being in a plurality of the access point groups, the first access point obtaining multiple phase alignment correction factors (PACFs) for different access point groups, the PACF values differing for the different access point groups;
- and
- for each of the at least one first access points, causing the first access point to transmit a respective first signal to at least one User Equipment (UE) associated with a first access point group of the plurality of access point groups, wherein the first access point group including the first access point, and wherein the first signal is phase adjusted using a respective PACF for the first access point based on the first access point group of the plurality of access point groups.
