Abstract: Disclosed are apparatuses and methods for a signaling procedure. An example method may include transmitting a first portion of a signaling message in a first sub-band and transmitting a second portion of the signaling message in a second sub-band, the second portion including an indication to the first portion transmitted in the first sub-band. Related apparatuses and computer readable medium are also disclosed.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.

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: A method and apparatus for communicating on multiple channels, perhaps in data duplication communications in unlicensed spectrum. The method comprises scanning a plurality of channels in unlicensed spectrum to determine whether the plurality of channels are available. In response to determining at least one of the channels is available determining when a transmitting opportunity may occur and estimating at least one delay between said transmitting opportunity and at least one further transmitting opportunity at which it is estimated that the apparatus may be able to transmit a signal on at least one other of said multiple channels. Determining hether any of said at least one delays lie within a current deferral allowance and where not transmitting the signal on the available hannel; and where so delaying transmitting the signal until a further transmitting opportunity within the current deferral allowance.

Abstract: A method, apparatus and computer program product are provided to receive, at a user equipment, an indication providing a cell location to which the user equipment, operating in a dual connectivity mode, should transmit a buffer status report for one or more bearers, the cell location being one of a first location, a second location, or a first location and second location and in response to being triggered, causing buffer status report to be transmitted to the location provided in the indication. In some embodiments, the bearer may be a split bearer. In some embodiments, the indication may be provided by RRC signaling, MAC signaling or physical layer signaling.

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform receiving, by a network device, information comprising a multiple transmission time interval uplink grant with cyclic redundancy check bits scrambled by a radio network temporary identifier; determining, by the network device of a communication network, a subset of data transmissions of a previous burst of data transmissions to be retransmitted by the network device; and performing by the network device retransmission of the subset of data transmissions using scheduled resources of the uplink grant. In addition, to perform determining, by a network node of a communication network, information comprising a multiple transmission time interval uplink grant with cyclic redundancy check bits scrambled by a radio network temporary identifier to identify a subset of data transmissions of a previous burst of data transmissions to be retransmitted by a network device; and sending the information towards the network device for use in retransmission of the subset of data transmissions using scheduled resources of the uplink grant.

Abstract: Apparatuses, methods and software for configured grant operation 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, wherein 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.
