REDUCING OVERHEAD IN SIDELINK TRANSMISSIONS
First Claim
1. A method by a user equipment, UE, comprising:
- receiving a first transmission;
assessing a channel property of the first transmission;
receiving a second transmission;
determining if a corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission;
in response to determining that the corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission, estimating the corresponding channel property of the second transmission based on the channel property of the first transmission; and
detecting the second transmission using the estimated corresponding channel property of the second transmission;
wherein determining if a corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission comprises determining that transmission resources used for the first and second transmissions are sufficiently close in time and/or frequency domains that a channel property is common to both transmissions.

Abstract
A method includes receiving a first transmission; assessing a channel property of the first transmission; receiving a second transmission; determining if a corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission; in response to determining that the corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission by determining that transmission resources used for the first and second transmissions are sufficiently close in time and/or frequency domains that a channel property is common to both transmissions, estimating the corresponding channel property of the second transmission based on the channel property of the first transmission; and detecting the second transmission using the estimated corresponding channel property of the second transmission.

11. A user equipment, UE comprising:
-
a transceiver; at least one processor circuit; and at least one memory coupled to the at least one processor circuit and the transceiver, and storing program code that when executed by the at least one processor circuit causes the at least one processor circuit to perform operations comprising; receiving a first transmission; assessing a channel property of the first transmission; receiving a second transmission; determining if a corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission; in response to determining that the corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission, estimating the corresponding channel property of the second transmission based on the channel property of the first transmission; and detecting the second transmission using the estimated corresponding channel property of the second transmission; wherein determining if a corresponding channel property of the second transmission can be estimated based on the channel property of the first transmission comprises determining that transmission resources used for the first and second transmissions are sufficiently close in time and/or frequency domains that a channel property is common to both transmissions. - View Dependent Claims (24, 25, 26)

12. A method by a scheduler, comprising:
-
scheduling first and second sidelink transmissions of a wireless transmitting node such that they are close enough in a dimension that they will be regarded at a wireless receiving node as quasi co-located transmissions; and causing the wireless transmitting node to transmit the second sidelink transmission to the wireless receiving node without at least one overhead symbol that is present in the first transmission. - View Dependent Claims (28)
