Abstract: Systems, methods, apparatuses, and computer program products for prioritized random access during handover are provided. One method may include transmitting, by a source network node, a handover request to a target network node. The handover request may include an indication of a recognition of prioritized random access for a user equipment. The method may also include receiving an acknowledgement from the target network node, building a reconfiguration message, for the user equipment, comprising a prioritized set of random access parameters, and transmitting, to the user equipment, the reconfiguration message comprising the prioritized set of random access parameters.

Abstract: Method, apparatuses, and computer program product for addressing random access responses with extended response windows. One method may include accessing, by a user equipment, a network by sending a random access channel preamble to a network element. The method may also include receiving, in response to the random access channel preamble, a random access response from the network element. The random access response provides an indication of which random access channel occasion in time within a span of one or a plurality of radio frames the random access response applies.

Abstract: In accordance with some embodiments, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least receive at least one random access preamble from user equipment. The at least one memory and the computer program code can be further configured to, configure at least one backoff indicator. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least transmit the at least one backoff indicator and at least one backoff configuration indicator to the user equipment. The at least one backoff configuration indicator is used to indicate how the at least one backoff indicator is applied.

Abstract: Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.

Abstract: Embodiments of the present disclosure relate to contention resolution in random access procedure. An apparatus transmits a random access request to a further apparatus, and the random access request comprises a random access preamble and an identifier of the apparatus for a random access procedure. The apparatus then receives, from the further apparatus, control information on a control channel addressed to the identifier, and the control information indicates at least one of a resource and timing information for communication between the apparatus and the further apparatus. Next, the apparatus determines a result of the random access procedure based at least in part on the control information.

Abstract: A method is provided including determining a mapping of a scheduling request to one or more logical channels configured for a user equipment; in response to a received scheduling request, allocating an uplink radio resource such that a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and receiving data on the allocated uplink radio resource. A further method includes transmitting a scheduling request mapped to one or more logical channels configured for a user equipment; receiving an allocation of an uplink radio resource wherein a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and sending data on the allocated uplink radio resource.

Abstract: Example embodiments of the present disclosure relate to channel information transmitting for dormant bandwidth part. According to embodiments, a solution for channel information transmitting for dormant bandwidth part has been proposed. A terminal device is configured a periodicity when an active downlink (DL) bandwidth part (BWP) is a dormant BWP. The periodicity is different from a further periodicity which is configured and used when the active DL BWP is a non-dormant BWP. The terminal device uses resourced configured for the active uplink (UL) BWP but with the different periodicity. In this way, it allows sounding reference signal (SRS)/channel state information (CSI) reporting without duplicating configurations of BWPs. It can configure a required longer periodicity but reduce the SRS configuration for each UL BWP.
