Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage media for determining a transport block size (TBS) for Contention Free Random (CFRA) in a random access procedure. In example embodiments, a CFRA request is transmitted by a terminal device to a network device during a random access procedure. The terminal device receives a random access to the CFRA request from the network device. The random access response indicates a TBS granted by the network device for use in transmission. Based on the granted TBS, the terminal device transmits, to the network device, a first data block with the granted TBS or a second data block to be transmitted and stored in a buffer. In the way, the data may be avoided, and the data transmission efficiency may be improved.

Abstract: Example embodiments relate to communication of uplink control information. A method implemented at a terminal device comprises obtaining a plurality of uplink grants available for uplink transmission to a network device, the plurality of uplink grants indicating resources for the uplink transmission; determining prioritization of the plurality of uplink grants in transmission of uplink control information based on a predetermined prioritization policy; and selecting, based on the determined prioritization, an uplink grant from the plurality of uplink grants for transmission of the uplink control information to the network device. In such a way, it is possible to increase a probability of transmission of the uplink control information and/or a probability of improving power efficiency of the terminal device.

Abstract: Embodiments of the present disclosure relate to mechanism for first random access mode falling back to second random access mode. According to embodiments of the present disclosure, the fallback to second random access mode is indicated in messageB and the user equipment only needs to monitor the messageB for the quick mode on the downlink control signal which is addressed to an identifier. The user equipment does not need to monitor the downlink control channel for the second random access mode. In this way, the user equipment is allowed to fall back to the second random access mode without further retry of the quick mode, thereby reducing overload and latency.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for random access procedure. The method comprises transmitting, at a terminal device, a random access request in a random access procedure to a network device; in response to receiving, in the random access procedure, from the network device an uplink grant for the terminal device, determining whether a first size of a first data unit indicated by the uplink grant matches a second size of a second data unit stored in a buffer of the terminal device; in response to determining that the first size mismatches the second size, determining a first part of the second data unit for subsequent transmissions.

Abstract: A technique of performing a handover within a 5G network include at least one of the following approaches. In one approach, a source gNB resets any mapping indicators from the forwarded SDAP PDUs, i.e., forwarded downlink data packets. Accordingly, subsequent uplink data packets will not be mapped according to the mapping tables of the source gNB. In another approach, the UE is configured to ignore mapping indicators of the forwarded downlink data packets. That is, in response to receiving a handover command message from the source gNB, the UE does not respond to updates of mapping tables from the source gNB. Again, subsequent uplink data packets will not be mapped according to the mapping tables of the source gNB.

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: Systems, methods, apparatuses, and computer program products for user equipment are provided. A method may include determining to transmit, upon data arrival on a logical channel, the data on a configured grant for the logical channel. The method may also include transmitting, based on the determination, the data on the configured grant to activate a cell. In an example embodiment, the transmission on the configured grant may be performed regardless of a current activation status of the cell for which the configured grant is configured, or a suspend status of the configured grant.

Abstract: Embodiments of the present disclosure relate to mechanism for providing multiple transmission opportunities. According to embodiments of the present disclosure, the network device transmits the random access response which includes an indication as to the number of transmission opportunities. If the random access response includes the preamble of the terminal device, the indication as to the number of transmission opportunities is applied to the terminal device. In this way, overheads are saved and the flexibility is improved.

Abstract: Various communication systems may benefit from improved random access operations. For example, certain embodiments may benefit from improved random access in which multiple bandwidth parts are configured to a user equipment within one cell. A method, in certain embodiments, may include triggering a random access procedure at a user equipment. The method may also include switching at the user equipment from a first uplink bandwidth part that does not support a random access channel to a second uplink bandwidth part that has the random access channel configured after the triggering of the random access procedure. The switching may be autonomously performed by the user equipment. In addition, the method may include performing the random access procedure at the user equipment using the random access channel configured at the second uplink bandwidth part.
