Abstract
Techniques for compensating timing advance for full duplex communications are disclosed. In an example, a user equipment (UE) may receive, from a base station, a timing advance value and a compensation factor. The UE may also determine a timing compensation amount indicating an amount of time to adjust an uplink (UL) transmission based on the timing advance value and the compensation factor. The UE may also transmit, to the base station, the UL transmission according to the timing compensation amount. Other features are also described.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory, the at least one processor configured to cause the apparatus to:
- receive a timing advance value and a compensation factor via a transceiver;
- transmit, via the transceiver, a first uplink (UL) transmission with a partial timing compensation amount based on a range between the timing advance value and a product of the timing advance value and the compensation factor;
- and
- transmit a second UL transmission with a full timing compensation amount equal to the timing advance value.
An apparatus for wireless communication at a network node, comprising:
- memory;
- and
- at least one processor coupled to the memory configured to cause the apparatus to:
- transmit a timing advance value for a user equipment (UE) based on a propagation delay between the network node and the UE;
- transmit, via a transceiver, a compensation factor for the UE to compensate the timing advance value for an uplink (UL) transmission;
- receive, via the transceiver, a first UL transmission with a partial timing compensation amount based on a range between the timing advance value and a product of the timing advance value and the compensation factor;
- and
- receive a second UL transmission with a full timing compensation amount equal to the timing advance value.
A method of wireless communication by a user equipment (UE), comprising:
- receiving a timing advance value and a compensation factor;
- transmitting a first uplink (UL) transmission with a partial timing compensation amount based on a range between the timing advance value and a product of the timing advance value and the compensation factor;
- and
- transmitting a second UL transmission with a full timing compensation amount equal to the timing advance value.
A method of wireless communication by a network node, comprising:
- transmitting a timing advance value for a user equipment (UE) based on a propagation delay between the network node and the UE;
- transmitting a compensation factor for the UE to compensate the timing advance value for an uplink (UL) transmission;
- receiving a first UL transmission with a partial timing compensation amount based on a range between the timing advance value and a product of the timing advance value and the compensation factor;
- and
- receiving a second UL transmission with a full timing compensation amount equal to the timing advance value.
