Example embodiments of the present disclosure relate to a solution for determining a set of physical random access channel (PRACH) occasions. In the solution, a first apparatus receives, from a second apparatus, configuration information indicating a plurality of PRACH occasions comprising PRACH occasions in uplink resource and PRACH occasions in sub-band non-overlapping full-duplex (SBFD) resource; determines, based on the configuration information, and for each frequency resource index for frequency multiplexed PRACH occasions, a starting PRACH occasion of a set of PRACH occasions for a PRACH transmission with preamble repetitions from the PRACH occasions in uplink resource and the PRACH occasions in SBFD resource, and performs, to the second apparatus, the PRACH transmission based at least in part on the starting PRACH occasion of the set.

Determination for uplink repetitions

A method and apparatus may include determining, by a network entity, at least one interval of at least one scheduling resource during which the at least one scheduling resource is in at least one of a first status or a second status. The method may further include transmitting, by the network entity, information associated with the at least one interval of at least one scheduling resource to at least one user equipment. The at least one interval may occur periodically, and the at least one of scheduling resource may include at least one of configured grant for uplink or semi-persistent scheduling resource for downlink.

Duty-cycle based configured scheduling

Systems, methods, apparatuses, and computer program products for improved handling of cross-link interference on physical random access channel occasions on flexible or full duplexing slots are provided. For example, a method can include providing a plurality of random access channel configurations to a user equipment. A first random access channel configuration of the plurality of random access channel configurations can be for a first set of symbols or slots and a second random access channel configuration of the plurality of random access channel configurations can be for a second set of symbols or slots. The method can also include providing, to the user equipment, one or more parameters configured to steer the user equipment to select between the first set of symbols or slots or the second set of symbols or slots to be used when performing a random access transmission. The method can further include receiving a random access transmission on the selected set of symbols or slots based on one of the plurality of random access channel configurations.

Handling of cross-link interference on physical random access channel occasions on flexible/full duplexing slots

A method, apparatus, and a computer-readable storage medium are provided for constructing a HARQ-ACK codebook for managing the trade-off between codebook size and feedback granularity. In an example implementation, the method may include a network node determining a second time domain resource allocation table and transmitting configuration information to the UE. The method may further include the network node transmitting downlink data to the UE and receiving the one or more ACKs and/or NACKs from the UE in response to the transmitting of the downlink data, the one or more ACKs/NACKs being generated based at least on the second time resource allocation table. In another example implementation, the method may include a user equipment (UE) receiving configuration information from a network node, receiving downlink data from the network node, and transmitting one or more ACKs/NACKs to the network node.

Flexible semi-static HARQ-ACK codebook overhead

There is provided a method, computer program, and apparatus for causing a network access node to perform: calculating a first offset value based on first acknowledgment and negative acknowledgement information for signals received during subband full duplex, SBFD, slots; calculating a second offset value based on second acknowledgement and negative acknowledgment information for signals received during uplink-only slots or during downlink-only slots; and using the first and second offset values to determine respective first and second modulation and coding schemes, MCS, to be used for transmissions made in a subband full duplex, SBFD, slots and either uplink-only slots or downlink-only slots.

Method, apparatus and computer program

An apparatus including circuitry configured for: transmitting a first data flow in resources of a first periodic resource configuration; and transmitting a second data flow in resources of a second periodic resource configuration, determining that there is an at least partial overlap in time between a first allocation of the first periodic resource configuration and a second allocation of the second periodic resource configuration; and in response to determining that there is the at least partial overlap, transmitting data of the first data flow and data of the second data flow in resources of at least one further periodic resource configuration.

Multi-configured grant support for multiple time-sensitive-network data flows

Various example embodiments provide efficient jitter control by means of a hybrid automatic repeat request (HARQ) process. Abase station may transmit to a UE a forwarding time parameter for data packet(s) associated with a HARQ process. The UEmay store the data packet(s) in a HARQ buffer and determine to hold the data packet(s) in the HARQ buffer until a delivery time determined based on the forwarding time parameter. Once the delivery time has been reached, the UE may forward the data packets to higher protocol layers. This enables efficient jitter control of a data packet flow. Apparatuses, methods, and computer programs are disclosed.

Jitter control with hybrid automatic repeat request process

It is provided a method, including determining a parameter of a data flow to pass through a non-deterministic network and a buffering device; configuring the data flow in at least one of a network element of the non-deterministic network and the buffering device based on the parameter, wherein the parameter is determined based on a capability of the buffering device.

Signalling of dejittering buffer capabilities for TSN integration

Techniques of ensuring that the survival time requirement is fulfilled include applying, by the UE (transmitter), a plurality of different logical channel (LCH) mapping restrictions to the packets on the same data radio bearer (DRB). In some implementations, the LCH mapping restrictions to be applied depend on the SN of the PDCP PDU to be processed. For example, the first LCH mapping restriction may be limited to radio resource with lower reliability (e.g., with the first LCH mapping restriction, the data from this LCH can only be mapped to a CG configuration without repetition and/or high MCS), while the second LCH mapping restriction may be limited to radio resources with extremely high reliability (e.g., with the first LCH mapping restriction, the data from this LCH can only be mapped to a CG configuration with repetitions and/or low MCS).

Packet-dependent logical channel restriction

A user equipment may receive a configuration message comprising at least one of: a configured grant configuration, or a semi-persistent scheduling configuration, wherein configuration may be associated with a cross-division duplexing slot format, wherein the cross-division duplexing slot format may comprise at least one of: a cross-division duplexing time slot for concurrent transmission in a plurality of communication directions, or a cross-division duplexing time slot for transmission in one communication direction; receive an information indicating at least one resource of the configuration; determine whether the at least one resource is valid, based on a comparison between a corresponding cross-division duplexing slot format of the at least one resource and the cross-division duplexing slot format associated with the configuration; and perform communication with the network device on the at least one resource based, at least partially, on a determination that the at least one resource is valid.

In an example implementation, the method may include a user equipment receiving a channel quality report configuration from a network node, the channel quality report configuration including a first transport block size. The method may further include determining a channel quality indicator based at least on the first transport block size and transmitting the channel quality indicator to the network node. In another example implementation, the method may include a network node determining a first transport block size, the first transport block size being a target transport block size, and transmitting a channel quality report configuration to a user equipment, the channel quality report configuration including the first transport block size. The method may further include receiving a channel quality indicator from the user equipment, the channel quality indicator determined at the user equipment based at least on the first transport block size transmitted from the network node.

Certain example embodiments provide systems, methods, apparatuses, and computer program products for enhanced traffic co-existence with multi-panel user equipment (UE). For example, certain embodiments may avoid excess dropping and/or cancellation. Taking inter-UE uplink (UL) prioritization as one example, whenever a network node has to accommodate higher-priority traffic on resources overlapping with ongoing and/or incoming lower-priority transmissions, certain embodiments may instruct a UE to transmit on spare antenna panel(s).
