Embodiments of the present disclosure relate to communications with preconfigured uplink resources (PUR). A method implemented at a terminal device comprises identifying a need to change a transmission configuration of the terminal device, the terminal device being in a transmission mode with a set of preconfigured uplink resources (PURs) allocated for the terminal device to transmit user data to a network device; and in response to identifying the need to change the transmission configuration, transmitting control information to the network device using a first PUR in the set of PURs, the control information comprising information relevant to the change of the transmission configuration. In this way, it is possible to enable the terminal device to save power, time, and resources by bypassing a full random access procedure when the transmission configuration is needed to be changed.

Communications with preconfigured uplink resources

According to an example aspect of the present invention there is provided apparatus including means for monitoring a physical downlink control channel of a cell for downlink control information; and means for, in response to detecting the downlink control information, determining whether a field of the downlink control information indicates that a reduced capability user equipment is supported in the cell.

Method to indicate cell support for reduced capability UE

According to a first embodiment, a method may include transmitting to at least one user equipment at least one configuration of channel quality indication comprising at least one indication of whether downlink transmissions associated with 16-quadrature amplitude modulation is supported. The method may further include receiving, based upon at least one condition being satisfied, from the at least one user equipment, at least one extended channel quality indication report.

Systems, methods, apparatuses, and computer program products for physical broadcast channel (PBCH) extension to manage extended master information block (MIB) are provided. A user equipment (UE) may determine whether an MIB extension exists. If the MIB extension exists, then the UE may determine an extended PBCH time-frequency location.

Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for channel state information (CSI) reporting. According to embodiments of the present disclosure, a first device receives from a second device a configuration for CSI reporting. The configuration comprises at least a block error rate target and an indication of a number of HARQ transmissions. The first device determines Channel Quality Indicator (CQI) based on the block error rate target and the number of HARQ transmissions indicated by the configuration and transmits a CSI report comprising the CQI to the second device. The solution enables CSI feedback that is suitable for spectrally efficient and reliable delivery of Point to Multipoint services while meeting the delay requirement, in particular in the context of NACK-only feedback on common feedback resources.

Channel state information reporting for point-to-multipoint operation

Techniques of transmitting and receiving HARQ feedback for point to multipoint data packets include using two different PUCCHs for providing ACK/NACK feedback to a sequence of point-to-multipoint (PTM) data packets. For example, when a gNB sends PTM data packets (e.g., as part of a subscription) to subscriber UE's, each UE sends ACK/NACK messages in response over a first PUCCH which has a smaller bandwidth than a conventional PUCCH under which full uplink control information (UCI) may be sent. In some implementations, the ACK/NACK messages are a single bit. In response to a NACK message from a UE, the gNB allocates a second PUCCH to the UE. The UE then send additional details to explain the NACK message. In some implementations, the additional details include an identifier of a missing data (e.g., packet m of n).

Method for efficient HARQ feedback using two levels of PUCCH reporting for multicast/broadcast users in NR

A system, apparatus, method, and non-transitory computer readable medium for system information acquisition for reduced capability NR devices may include a UE device which is caused to, determine a plurality of physical downlink control channel (PDCCH) candidates from a control resource set (CORESET), monitor a PDCCH from the plurality of PDCCH candidates, determine reduced capability (REDCAP) scheduling information from a downlink control information (DCI) received on the PDCCH, and receive REDCAP system information based on the determined REDCAP scheduling information.

Embodiments of the present disclosure relate to frequency domain resource allocation for multicast traffic. A method comprises: receiving, at a first device and from a core network element, multicast traffic to be scheduled for a second device; generating assistance information for the second device, the assistance information enabling the second device to identify, within a bandwidth part configured for the second device, a frequency domain resource allocated for the multicast traffic; and transmitting the assistance information to the second device. The method further comprises: receiving, at the second device, the assistance information from a first device; and determining the frequency domain resource from downlink control information based on the assistance information. In this way, a significant flexibility to schedule multicast traffic can be provided, and a significant complexity reduction to a terminal device can be provided.

Frequency domain resource allocation for multicast traffic

Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for counting of devices. In example embodiments, a first device receives, from a second device, a first configuration associated with an event to trigger transmission of a counting signal from the first device to the second device. When the event occurs, the first device transmits, to the second device, at least the counting signal to enable the second device to count the number of devices for determining a type of signals.

Counting of devices

At a UE configured with an idle-mode configuration for using a PUR, determining that data not associated with the PUR is to be transmitted or received via an RRC connection. The UE performs an initial access to a network for the radio resource control connection. The UE transitions from RRC idle mode to RRC connected mode. The UE performs one of suspending the idle-mode configuration or maintaining the idle-mode configuration, for at least a duration of the RRC connected mode. A base station received the initial access, determines the UE is configured with the idle-mode configuration for using a PUR and transitions the UE from RRC idle mode to RRC connected mode. The base station performs communication between the base station and the UE to perform action(s) to modify one or both of the idle-mode configuration or an RRC connection corresponding to the transition into the RRC connected mode.

Maintaining, suspending, or modifying existing PUR configuration in response to a UE entering into RRC connected mode

One method may include receiving an allocation of a preconfigured uplink resource and a preconfigured uplink resource radio network temporary identifier associated with the preconfigured uplink resource. The method may also include receiving an assignment of a control channel search space associated with the preconfigured uplink resource. The method may further include monitoring, according to a specified occasion cycle, the control channel search space for a message. In addition, the message may be received according to a specific receive pattern.

Preconfigured uplink resource control signaling enhancements

Embodiments of the present disclosure relate to methods, devices and computer readable storage medium for transport block size (TBS) configuration. In example embodiments, a terminal device transmits a random access preamble to a network device. The terminal device receives a random access response from the network device. The random access response includes a resource allocated for a reference TBS. Based on the reference TBS, the terminal device determines a TBS for transmitting data to the network device. Then, the terminal device transmits the data to the network device by using the determined TBS and the allocated resource. This TBS configuration is more flexible.

Configuration of transport block size

Such a transmission includes system information for a second radio access technology, wake-up signal, synchronization signal, and/or extension of the data transmission. Thereafter, the base station transmits such a transmission in the at least one time-frequency region that was indicated.
