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: Example embodiments relate to wideband communications based on availability assessment. A method for communication comprises performing availability assessment on a set of configured frequency subbands to obtain an availability result, the availability result indicating that at least one of the set of configured frequency subbands is available for a period of time for transmission of intended information and transmitting supplementary information that has been prepared using the at least one frequency subband during a first portion of time within the period of time. The method also comprises preparing the intended information based on the availability result and transmitting the prepared intended information using the at least one frequency subband during a second portion of time following the first portion of time within the period of time. As such, the processing of the intended information can be adapted depending on the dynamic available subband(s) indicated by the availability result.

Abstract: Methods include performing, by a terminal device, downlink control channel monitoring according to a first time pattern. The methods include determining that data has been transmitted on downlink on a number of symbols and based on the determination that the data is transmitted, suspending the performing of downlink control channel monitoring according to the first time pattern. The methods also include performing downlink control channel monitoring on at least one symbol after transmission of the data.

Abstract: Apparatuses, methods and software are provided. The first apparatus 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 transmit a transport block of a HARQ process on preconfigured resources for an uplink transmission to a second apparatus while starting a first timer and a second timer for the HARQ process. The first timer indicates a time period during which the transport block is able to be retransmitted, and wherein the second timer is configured to expire before the first timer; monitor a response associated with the transport block from the second apparatus; and in response to the second timer expiring before receiving the response and before expiry of the first timer, retransmit the transport block while restarting the second timer.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission mechanism for configured grant uplink transmission. The method comprising transmitting, to a second device, a transport block while starting a configured grant retransmission timer for autonomous retransmission of the transport block; in response to receiving, from the second device, a feedback indicating unsuccessful reception of the transport block, adjusting expiry time of the configured grant retransmission timer without starting the autonomous retransmission of the transport block; determining whether scheduling information for retransmission of the transport block is received before the adjusted configured grant retransmission timer expires; and in response to determining that the scheduling information is received, retransmitting the transport block while stopping the configured grant retransmission timer. In this way, the retransmission in the Hybrid Automatic Repeat Request process could be performed according to the uplink grant scheduled by the network device and therefore the retransmission efficiency for configured grant uplink transmission in unlicensed spectrum can be improved.
