摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides an apparatus, a method and a system for MBS multicast reception and small data transmission. A method performed by a terminal includes receiving, from a BS, an RRC release message including information indicating a suspend configuration for an RRC inactive state; identifying whether an SDT procedure is ongoing in the RRC inactive state, in case that there is a configuration by an upper layer for MBS multicast reception; and monitoring a paging channel for paging using a TMGI associated with an MBS session, based on the SDT procedure being not ongoing. The MBS session is associated with a bearer for the MBS multicast reception.

摘要： A communication system broadcasts utterance voice data of one of users to mobile communication terminals carried by respective users. Responsive to pressing an utterance button during a group calling communication mode in which a reception channel is established for utterance voice data transmitted from a server, the mobile communication terminal establishes a transmission channel transmitting utterance voice data to the server independently of the established reception channel, transmits utterance voice data from that mobile communication terminal, and receives utterance voice data within the communication group simultaneously. The mobile communication terminal stores a simultaneous connection upper limit in full-duplex transmission and a full-duplex transmission log including simultaneously connecting users and number of simultaneously connecting users. Limited full-duplex transmission control is performed on each terminal not permitting establishment of the transmission channel to the server based on the full-duplex transmission log and simultaneous connection upper limit.

摘要： Systems and methods are described for using opportunistically delayed delivery of content to address sub-optimal bandwidth resource usage in network infrastructures that allow subscribers to share forward link resources. According to some embodiments, content is identified as delayable and assigned to a delaycast queue and/or service flow. For example, a server system of a satellite communications system identifies content that can be delayed to exploit future excess link capacity through multicasting and to exploit subscriber-side storage resources. Some implementations attempt to exploit any excess link resources at any time, while others exploit unused bandwidth only during certain times or when a certain threshold of resources is available. Various embodiments also provide content scoring and/or other prioritization techniques for optimizing exploitation of the delaycast queue.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a second user equipment, an indication of a time buffer threshold associated with providing sidelink hybrid automatic repeat request feedback on a physical sidelink feedback channel. The UE may receive, from the second user equipment, an indication of an agreement to use the time buffer threshold. The UE may transmit, to the second user equipment and based at least in part on the indication of the agreement, sidelink hybrid automatic repeat request feedback for a sidelink communication received from the second user equipment, the sidelink hybrid automatic repeat request feedback being transmitted on the physical sidelink feedback channel based at least in part on the time buffer threshold. Numerous other aspects are provided.

摘要： Provided are wireless communication methods for D2D communication and UEs therefor. A wireless communication method involves transmitting either a first DCI or a second DCI based on whether a first UE and a second UE are to be in a communication type of groupcast or unicast. In the wireless communication methods, the first DCI and the second DCI are scrambled by the UE ID of the second UE if the first UE and the second UE are in the communication type of unicast upon transmitting the first DCI and the second DCI, and the first DCI and the second DCI are scrambled by the group ID if the first UE and the second UE are in the communication type of groupcast upon transmitting the first DCI and the second DCI.

摘要： This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a user equipment (UE) is configured to manage a state variable (associated with a radio link control (RLC) entity or a packet data convergence protocol (PDCP) entity) that enables the UE to maintain synchronization with a base station during a communication session. For example, a base station may transmit, to the UE, a control PDU or a synchronization PDU that includes a value of a state variable maintained by a base station to enable the UE to update its state variable to maintain synchronization with the base station. Other aspects and features are also claimed and described.

摘要： This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of control resource sets for reduced bandwidths. In a first aspect, a method of wireless communication includes receiving, from a base station at a user equipment (UE) having a first type, a master information block (MIB) within a physical broadcast channel (PBCH). The MIB includes CORESET size information and search space information for devices having a second type. The method also includes selecting a CORESET size from a plurality of preconfigured CORESET sizes based on a subcarrier spacing used to communicate with the base station. The method further includes monitoring a set of time and frequency resources to receive a message from the base station. The set of time and frequency resources has the selected CORESET size. Other aspects and features are also claimed and described.
