A method of wireless communications by a user equipment (UE) determines whether a downlink positioning reference signal (PRS) overlaps in time with an uplink transmission within a full duplex slot. The method adjusts the uplink transmission to address the overlap. The adjusting can use an uplink grant to achieve a gap between the PRS and the uplink transmission. The adjusting can puncture a number of resource elements assigned for the uplink transmission. The resource elements are positioned adjacent to the PRS. The adjusting can reduce transmit power. The method can include receiving a priority order for the PRS and multiple uplink transmission types. In this case, the adjusting comprises dropping the uplink transmission in accordance with the priority order.

An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: receiving at least one signal comprising control information; determining data to transmit using grant-free data transmission; determining whether grant-free data transmission using time-frequency repetition is permitted for the grant-free data transmission in dependence on the received control information; if it is determined that use of time-frequency repetition for the grant-free data transmission is permitted, causing transmission of grant-free data transmission using time-frequency repetition; and if it is determined that use of time-frequency repetition for the grant-free data transmission is not permitted, causing transmission of grant-free data transmission without using time-frequency repetition.

Certain aspects of the present disclosure propose methods for improving phase continuity in an uplink transmit time interval (TTI) bundle. A first method may include identifying a segment of UL subframes in the TTI bundle and maintaining substantially the same transmit power/timing/frequency when transmitting data to a node over the segment of UL subframes in the TTI bundle. Another method may include ignoring reception of downlink subframes for a duration of the TTI bundle.

Techniques are directed to using communication metric data associated with multiple modulation schemes to achieve a link quality metric that is representative of the link as a whole, across the multiple modulation schemes that may be employed on the link. A calculation of a link quality metric may be triggered by a network layer transmission attempt, with communication metrics accumulated at the link layer of the link. A filter used to calculate the link quality metric may be updated based on network layer transmission attempts, based on successful and/or unsuccessful transmissions at a Media Access Control (MAC) layer of the link. More generally, a calculation of link quality may be triggered by a higher layer transmission attempt while being calculated based on transmission attempts at a lower layer of the link.

Certain aspects of the present disclosure relate to methods and apparatus for flexible resource mapping and modulation and coding scheme (MCS) determination in wireless communication systems. According to certain aspects, a method for wireless communications that may be performed by a transmitter is provided. The method generally includes determining MCSs to use for each of multiple portions of a transport block and transmitting the portions of the transport block according to the determined MCSs to a wireless node. Flexible MCS and resource mapping determination may improve demodulation performance for code blocks that are far from pilots.

A method of wireless communication may include monitoring, by a first device, a medium for frames in response to preparing to transmit a first frame to a second device. The method may also include while monitoring the medium and before transmitting the first frame, obtaining a second frame transmitted by a third device in the medium and adjusting a transmission of the first frame to the second device in the medium based on obtaining the second frame.

Aspects relate to adaptation of the modulation and coding scheme (MCS) of a downlink transmission to a scheduled entity that overlaps in time with an uplink transmission from the scheduled entity when the scheduled entity is operating in a full-duplex mode. A transport block corresponding to the downlink transmission may include a plurality of code block groups (CBGs). When at least a portion of the CBGs overlap in time with the uplink transmission, the MCS of the entire transport block or the MCS of the overlapping CBGs may be adjusted to accommodate and/or mitigate interference between downlink and uplink transmissions. The CBGs may further be time-interleaved over a plurality of symbols allocated for the downlink transmission to accommodate and/or mitigate interference between downlink and uplink transmissions. Other aspects, features, and embodiments are also claimed and described.
