Abstract: Embodiments of the present disclosure relate to apparatuses, methods and computer readable storage media for contention window size (CWS) adjustment feedback. The first device comprises at least one processor; and at least one memory including computer program codes; the at least one memory and the computer program codes are configured to, with the at least one processor, cause the device at least to receive at least one transport block from a second device on a predetermined bandwidth part for a transmission from the second device to the first device, the at least one transport block transmitted in a set of subbands of the predetermined bandwidth part; generate a feedback based on a set of reception states of the at least one transport block in the set of subbands; and transmit the feedback to the second device so that the second device adjusts a contention window size (CWS) for a further transmission from the second device to the first device. In this way, a feedback corresponding to interference conditions with a certain subband may be provided for the CWS adjustment and the signalling overhead is significantly reduced.

Abstract: A method may include receiving, by a user equipment from a network entity, a first downlink (DL) control signal activating semi-persistent scheduling (SPS) of a first set of downlink data transmissions, the downlink control signal indicating an applicable hybrid automatic repeat request (HARQ) feedback timing for the first set of downlink data transmissions and receiving one or more of the first set of downlink data transmissions. The user equipment may determine that an applicable HARQ feedback timing for a second set of downlink data transmission previously received with an inapplicable HARQ feedback timing has not been provided. In response to the determination, the user equipment may determine a HARQ feedback timing for the one or more of the first set of downlink data transmissions based a second DL control signal indicating an applicable HARQ feedback timing received after reception of the one or more of the first set of downlink data transmissions.
