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: In accordance with an embodiment, a method may include determining, by a user equipment, a beam management group comprising one or more serving cells. The method may further include detecting, by the user equipment, a beam failure on at least one serving cell of the beam management group. The method may further include transmitting, by the user equipment, a beam failure recovery request to the at least one serving cell of the beam management group.

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.

Abstract: Example embodiments of the present disclosure relate to beam failure recovery mechanism. According to embodiments of the present disclosure, there are provided an improved solution for reporting candidate beams in serving cells. If a beam failure occurs in a serving cell, the first device determines a candidate beam for beam failure recovery from a plurality of beams in the serving cell based on link qualities of the plurality of beams. The first device also determines a resource configuration for a random access for the beam failure recovery for the first device or a resource to be used for the random access, The first device further generates an indication for indicating a characteristic of the candidate beam or a characteristic of a beam for performing the random access, based on at least one of the determined resource configuration or the determined resource. The first device also transmits an identity of the candidate beam and the indication to a second device. The second device performs the beam failure recovery based on the candidate beam and the characteristic of the candidate beam.
