Abstract
In some implementations, a control device may transmit, to a set of radio units (RUs), an indication of orthogonal codes for respective RUs from the set of RUs, wherein the set of RUs are non-collocated. The control device may transmit, to one or more user equipment (UEs), an indication of the orthogonal codes for the respective RUs from the set of RUs. The control device may transmit, to the set of RUs, control information to cause the set of RUs to transmit orthogonal transmissions, using the orthogonal codes, to at least one UE from the one or more UEs.
Claims20
A method, comprising:
- transmitting, by a control device and to a set of radio units (RUs), an indication of orthogonal codes for respective RUs from the set of RUs,
- wherein the control device is configured to dynamically update the orthogonal codes based on instantaneous channel information as a physical location of a user equipment (UE) changes, and
- wherein the set of RUs are non-collocated;
- transmitting, to one or more UEs, an indication of the orthogonal codes;
- and
- transmitting, by the control device and to the set of RUs, control information to cause the set of RUs to transmit orthogonal transmissions, using the orthogonal codes, to at least one UE from the one or more UEs.
A user equipment (UE), comprising:
- one or more processors configured to:
- receive, from a device, an indication of orthogonal codes for respective radio units (RUs) of a set of RUs, wherein the orthogonal codes are dynamically updated based on instantaneous channel information as the UE moves through coverage areas;
- receive, via a set of non-collocated antenna ports and from one or more RUs of the set of RUs, a set of signals associated with a communication;
- and
- decode, using one or more orthogonal codes of the orthogonal codes, the set of signals to obtain the communication.
A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a control device, cause the control device to:
- transmit, to a set of radio units (RUs), an indication of orthogonal codes for respective RUs from the set of RUs,
- wherein the control device is configured to dynamically update the orthogonal codes based on instantaneous channel information as a user equipment (UE) moves through coverage areas, and
- wherein the set of RUs are non-collocated;
- transmit, to one or more UEs, an indication of the orthogonal codes;
- and
- transmit, to the set of RUs, control information to cause the set of RUs to transmit orthogonal transmissions, using the orthogonal codes, to at least one UE from the one or more UEs.
