Abstract: Methods, systems, and apparatus for supporting uplink Transmission Time Interval (TTI) bundling in Long Term Evolution (LTE) are provided. Methods, systems, and apparatus for signaling, activation/deactivation, and wireless transmit/receive unit (WTRU) behavior are also provided. In an example, a downlink control information (DCI) associated with a repeated physical uplink shared channel (PUSCH) transmission may be received. A hybrid acknowledgment repeat request (HARQ) process information may be determined using the received DCI. A repeated PUSCH transmission may be sent in accordance with one or more time units, the repetition configuration, and the HARQ process information.

Abstract: Embodiments herein relate to a method performed by a transmitting device (120) for handling communication in a wireless communications network, wherein the transmitting device (120) comprises at least two radio link control, RLC, entities and is configured with a split bearer to a receiving device (100). The transmitting device (120) identifies that a last transmitted protocol data unit, PDU, of one of the at least two RLC entities, is lacking a poll indicator requesting a status of one or more transmitted PDUs. When identifying that the last transmitted PDU lacks the poll indicator, the transmitting device transmits to the receiving device (100), a PDU comprising a poll indicator.

Abstract: Methods, systems, and devices for wireless communications are described in which sidelink communications between devices may be retransmitted using one or more nodes. A first user equipment (UE) may transmit a broadcast, multicast, or groupcast communication to a set of other UEs using sidelink resources. A node may monitor the communications and store the first UE transmission. UEs of the set of other UEs may transmit feedback reports to the node that indicate one or more missing packets of the first UE transmission. The node may retransmit one or more of the stored packets to the set of other UEs based on the feedback reports. In some cases, the sidelink communications may be encoded using a network coding algorithm, and the node may retransmit network coded packets based on the feedback reports, may transmit newly encoded packets based on the feedback reports, or combinations thereof.

Abstract: The present invention relates to a network device comprising: a first input interface, a first output interface, and a second output interface, wherein the network device is configured to change from a first state, referred to as a time state, to a second state, referred to as a spatial state, and vice versa, wherein the network device is configured to generate each of a first output message and a second output message based on a first input message, wherein the network device is configured to transmit, in the time state, both, the first output message and the second output message, offset in time either via the first output interface or second output interface, and wherein the network device is configured to transmit, in the spatial state, the first output message via the first output interface and the second output message via the second output interface. The present invention also relates to a communication system comprising the network device and to a method for the network device.

Abstract: A method for collecting duplicated packets from a plurality of nodes provided on a network includes receiving a traffic profile which includes one or more parameters of packets which are to be captured by the plurality of nodes. The method further includes transmitting the traffic profile to each of the plurality of nodes provided on the network and receiving duplicated packets from the plurality of nodes. The duplicated packets correspond to packets which have been duplicated from packets which are captured by the plurality of nodes and satisfy the traffic profile.

Abstract: A communications method includes: sending a scheduling request to a terminal device through a PDCCH, where the scheduling request indicates the terminal device to send data to a network device based on a preset time interval; in response to not receiving the data that is sent by the terminal device through a PUSCH, determining, based on measurement gap configuration information of the terminal device, whether a time point at which the terminal device does not send the data is within a measurement gap window; and if it is determined that the time point at which the terminal device does not send the data is within the measurement gap window, sending, to the terminal device, a redundancy version number used for a next HARQ retransmission.

Abstract: Disclosed is a method comprising receiving a data packet from an access node, combining the received data packet with previous repetitions of the data packet to obtain a combined data packet, attempting to decode information comprised in the combined data packet, determining that the attempt to decode was not successful, determining an estimate of energy required for a correct reception of the data packet and based, at least partly, on the determined estimation for the energy, determining an additional number of repetitions of the data packet.

Abstract: Wireless communications systems and methods related to unscheduled uplink hybrid automatic repeat request (HARQ) data transmissions in a shared radio frequency band are provided. A user equipment (UE) determine priorities for a plurality of transport blocks (TBs) associated with a plurality of hybrid automatic repeat request (HARQ) processes for transmission during configured transmission periods. The UE transmits, to a base station (BS), the plurality of TBs in a shared radio frequency band during the configured transmission periods based on the determined priorities.

Abstract: Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a system information block (SIB) that indicates a selected set of message repetition numbers from a plurality of sets of message repetition numbers. The UE may receive, from the base station, a bit field in a random access response (RAR) or downlink control information (DCI) that indicates a selected message repetition number from the selected set of message repetition numbers indicated in the SIB. The UE may transmit, to the base station, a message during a random access procedure based at least in part on the selected message repetition number. Numerous other aspects are described.
