摘要： A communication technology that provides for handling of failed packet transmissions to reduce retransmission attempts and uses resynchronization to prevent tearing down of connections. Thereby, providing for more resilient connections. In an implementation, an initiator entity may determine that a negative acknowledgment indicates that an operation for a particular packet is completed in error by a target entity, and transmit to the target entity a resynchronization packet without tearing down the connection.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive a groupcast retransmission from one or more UEs of the group. For example, a base station may transmit a groupcast transmission to the group of UEs. A first UE of the group of UEs may fail to receive the groupcast transmission and, in response, may transmit a feedback message via a sidelink feedback resource to a second UE of the group of UEs. The feedback message may include a negative acknowledgement (NACK) that indicates the failed reception of the groupcast transmission by the first UE, and the sidelink feedback resource may be indicated by the base station. The second UE may transmit a retransmission of the groupcast transmission to the first UE via a sidelink resource based on receiving the feedback message.

摘要： Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.

摘要： A method includes sending wireless data to a receiver node and receiving feedback from the receiver node that identifies a subset of the wireless data that the receiver node failed to receive correctly and that includes a token value as a label for the subset of the wireless data as a group. The method includes constructing retransmission wireless data that includes the subset of the wireless data and the token value. The method includes sending the retransmission wireless data to the receiver node. The receiver node may be a first client device. The method further includes allocating a first set of token values to the first client device and a second set of non-overlapping token values to a second client device in a network. The method includes respectively notifying the first and second client device of the corresponding set of token values for retransmissions requested by the corresponding client device.

摘要： Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, a plurality of first data transmissions scheduled by first DCI and a second data transmission scheduled by second DCI; and transmits, to the network device, a first HARQ feedback for the plurality of first data transmissions and a second HARQ feedback for the second data transmission, the first HARQ feedback comprising a NACK for a first data transmission in the plurality of first data transmissions that is collided with a configured uplink symbol. In this way, a rule is defined for generation of the HARQ feedback for the multiple data transmissions upon the above collision.

摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for allocating Physical Uplink Control Channel (PUCCH) resources, including: a User Equipment (UE) detects a Physical Downlink Control Channel (PDCCH) scheduling a Physical Downlink Shared Channel (PDSCH) in a configured control resource set; the UE analyzes the detected PDCCH, correspondingly receives PDSCH, and determines PUCCH resources feeding back Hybrid Automatic Repeat request-ACK (HARQ-ACK) information; the UE transmits the HARQ-ACK information by using the determined PUCCH resources. By adopting the method in the present disclosure, a method for allocating PUCCH resources is provided. An upper-limit resource utilization is improved. And a method for indicating PUCCH resources in Downlink Control Information (DCI) is put forward, thereby reducing bit overheads of DCI.
