Abstract: Systems, methods, apparatuses, and computer program products for skipping TB transmission depending on UCI transmission are provided. One method includes receiving, by a UE, a configuration message from a network node. The configuration message may indicate to the UE a configuration of skipping uplink (UL) transmission when there is no uplink data. The method may then include determining whether the UE is requested for uplink control information (UCI) transmission for a subframe with UL grant. If it is determined that the UE is requested for UCI transmission, then the method may include generating and transmitting a transport block containing padding buffer status report (BSR).

Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device receives a criterion to select a random access type for performing random access to a second device. The first device further determines whether the first device is allocated a contention-free random access resource for a certain random access type, and then performs the random access to the second device based on the determination and conditionally based on the criterion. As such, in the case where contention-free random access resource has been allocated for a certain random access type, the device can conditionally apply the criterion for selection of the random access type and can thus perform random access with improved efficiency.

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: Various communication systems may benefit from the appropriate control of the timing of communication. For example, certain wireless communication systems may benefit from packet data convergence protocol windows, for example in the case of split bearers being in use. A method can include transmitting a plurality of protocol data units over a bearer mapped to a plurality of logical channels. The protocol data units can be transmitted in a radio link control unacknowledged mode. The method can also include managing at least one transmission characteristic of the transmitted plurality of protocol data units.

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: 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: Embodiments of the present disclosure relate to random access in a communication system. A first device determines whether a contention-free random access resource is allocated from a second device for a first random access type. In accordance with a determination that the contention-free random access resource is allocated, the first device compares a target transport block size corresponding to the contention-free random access resource with a first transport block size configured for a first group of preambles available for the first random access type, and performs random access to the second device based on a result of the comparison.

Abstract: Embodiments of the present disclosure relate to methods and devices for transmission by selecting between uplink resources. According to a method implemented by a terminal device in a communication system, a configuration of a first resource is received from a network device, the first resource being a grant-free resource. An uplink grant is received from the network device, indicating a second resource for use in a transmission time interval. The terminal device determines, based on the configuration of the first resource, whether the first resource is available in the transmission time interval. In response to determining that the first resource is available and possibly in response to a predefined condition associated with a logical channel for the terminal device is met, the terminal device transmits uplink data to the network device using the first resource.
