Abstract
A device and method for transmission and reception of control and data channels with a group reference signal (GRS). A GRS may include a first common reference signal associated with a first group of users and a second common reference signal associated with a second group of users. Some users or channels can be grouped to use one set of common reference signals and other users or channels can be grouped to use another set of common reference signals.
Claims25
A method for wireless communications, the method comprising:
- transmitting, by a network controller to a user equipment (UE), a first set of reference signals;
- receiving, by the network controller, feedback information from the UE of a first subset of the first set of reference signals selected by the UE;
- transmitting, by the network controller to the UE, a second set of reference signals;
- and
- indicating, by the network controller to the UE, a linkage of same receive beams at the UE being used for each reference signal in the second set of reference signals and one reference signal of the first subset of the first set of reference signals.
A network controller in a wireless network for communicating with a user equipment (UE), the network controller comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- transmit a first set of reference signals to the UE and a second set of reference signals to the UE;
- receive feedback information from the UE of a first subset of the first set of reference signals selected by the UE;
- and
- indicate, to the UE, a linkage of same receive beams at the UE being used for each reference signal in the second set of reference signals and one reference signal of the first subset of the first set of reference signals.
A method in a user equipment (UE) for communicating in a wireless network, the method comprising:
- receiving, by the UE, a first set of reference signals from a network controller;
- transmitting, by the UE, feedback information to the network controller of a first subset of the first set of reference signals selected by the UE;
- receiving, by the UE, a second set of reference signals from the network controller;
- and
- receiving, by the UE, an indication of a linkage of same receive beams at the UE being used for each reference signal in the second set of reference signals and one reference signal of the first subset of the first set of reference signals.
A user equipment (UE) for communicating in a wireless network, the UE comprising:
- a non-transitory memory storage comprising instructions;
- and
- one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to:
- receive a first set of reference signals from a network controller;
- transmit feedback information to the network controller of a first subset of the first set of reference signals selected by the UE;
- receive a second set of reference signals from the network controller;
- and
- receive an indication of a linkage of same receive beams at the UE being used for each reference signal in the second set of reference signals and one reference signal of the first subset of the first set of reference signals.
