US 12,763,840 B2 · Communicating based on quasi-collocation properties

Abstract

Apparatuses, methods, and systems are disclosed for communicating based on quasi-collocation properties. One method includes receiving, at a first wireless communication node, a control message from a second wireless communication node. The control message includes a plurality of reference signal indices indicating quasi-collocation properties according to whether a first communication by a first functional entity and a second communication by a second functional entity is restricted based at least in part on the first communication being simultaneous with the second communication. The method includes determining whether the second functional entity performs the second communication based in part on the control message.

Dependent claims

An apparatus for performing a network function, the apparatus comprising:

at least one memory;
and
at least one processor coupled with the at least one memory and configured to cause the apparatus to:
receive, at a first wireless communication node, a control message from a second wireless communication node, wherein the control message comprises a plurality of reference signal indices indicating quasi-collocation properties according to whether a first communication by a first functional entity and a second communication by a second functional entity is restricted based at least in part on the first communication being simultaneous with the second communication;
and
determine whether the second functional entity performs the second communication based in part on a simultaneous communication of the first communication by the first functional entity and the second communication by the second functional entity being restricted, as indicated by the plurality of reference signal indices.

An apparatus for performing a network function, the apparatus comprising:

at least one memory;
and
at least one processor coupled with the at least one memory and configured to cause the apparatus to:
receive, at an integrated access and backhaul (IAB) node, a medium access control (MAC) control element (CE) message from a parent node, wherein the MAC CE message comprises a plurality of reference signal (RS) indices indicating quasi-collocation properties according to which a first transmission or a first reception by an IAB mobile terminal (IAB-MT) and a second transmission or a second reception by an IAB distributed unit (IAB-DU) is restricted based at least in part on the first transmission or the first reception being simultaneous with the second transmission or the second reception;
and
determine whether the IAB-DU performs the second transmission or the second reception according to a simultaneous communication of a first transmission or a first reception by the IAB-MT and the second transmission or the second reception by the IAB-DU being restricted, as indicated by the plurality of reference signal indices and based in part on the at least one processor being configured to cause the apparatus to:
determine whether the IAB node is configured with a multiplexing case not constrained to time-division multiplexing (TDM) while using at least one reference signal index in the plurality of the reference signal indices;
determine whether a symbol or a group of resource blocks on which to perform the second transmission or the second reception is configured as a soft symbol or a soft group of resource blocks and indicated available by an availability indication;
determine whether a transmission configuration indication (TCI) state, a reference signal (RS) resource index, a sounding reference signal (SRS) resource indicator (SRI), or a combination thereof associated with the IAB-MT is used for the first transmission or the first reception;
determine whether the first transmission or the first reception and the second transmission or the second reception are performed on overlapping symbols, overlapping resource blocks (RBs), overlapping groups of resource blocks, or a combination thereof;
or a combination thereof.
