Apparatuses, methods, and systems are disclosed for system information block sizing. One method includes determining whether a first size of a first SIB is greater than a remaining size in a SI message. The system information message includes a second SIB having a second size. The method includes, in response to the first size of the first SIB being greater than the remaining size in the SI message, segmenting the first SIB into multiple segments including a first segment and at least one second segment. A segment size of the first segment is less than or equal to the remaining size in the SI message. The method includes including the first segment of the multiple segments of the first SIB in a third SIB. The system information message includes the second SIB and the third SIB.

System information block sizing

Apparatuses, methods, and systems are disclosed for enforcing a group-specific maximum bit rate. One method includes receiving a configuration for a set of logical channels (LCHs) and receiving a configuration for a group token bucket associated with a subset of the set of LCHs, the configuration for the group token bucket including an aggregated maximum bit rate and a bucket size duration. The method includes maintaining a variable Bassociated with the group token bucket, the variable Brepresenting a number of bits to be used for transmission of one or more data units of the subset of LCHs. The method includes multiplexing data from the set of LCHs based on the variable Band transmitting the multiplexed data in a transport block.

Aggregated maximum bit rate for logical channels

A method and apparatus are provided, in which a service link path delay relative to a first leg of a communication path of a communication between the user equipment and a network entity via a relay entity is estimated (), where the first leg corresponds to a portion of the communication path between the user equipment and the relay entity. A feeder link path delay relative to a second leg of the communication path is determined (), where the second leg corresponds to a portion of the communication path between the relay entity and the network entity, based upon at least a received signaling indication. A timing advance value is calculated (), based upon the service link path delay and the feeder link path delay. An uplink transmission timing of the user equipment is adjusted (), based upon the calculated timing advance value.

Uplink timing maintenance for communication paths including multiple legs involving a relay entity

Embodiments of the present disclosure relate to methods and apparatuses for multicast and broadcast services (MBS). According to an embodiment of the present disclosure, a method may include: determining whether a user equipment (UE) in an RRC_IDLE state or RRC_INACTIVE state should enter an RRC_CONNECTED state for reception of at least one MBS session; and transmitting indication information for indicating whether the UE should enter the RRC_CONNECTED state.

Methods and apparatuses for multicast and broadcast services

The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method includes: transmitting, at an access node, a failure information message to a base station, wherein the access node is connected to the base station via a master node and a secondary node, and wherein the failure information message includes a failure type of a backhaul link. The failure type is based on a failure type set including at least the following: an expiry of a physical layer problem timer, a random access problem, and reaching a maximum number of retransmission in response to radio link failure (RLF).

An operation mode from a plurality of operation modes can be determined () based on at least one traffic type originated from a UE. The plurality of operation modes can include at least one group operation mode and an individual operation mode. The at least one group operation mode can support a plurality of UEs grouped into a group of UEs. The at least one group operation mode can support at least one network entity communicating associated messages with the group of UEs including the UE. The associated messages can be associated with the group of UEs. A network entity can be informed () of the determined operation mode.

Apparatus and method of determining an operation mode on a wireless network

Various aspects of the present disclosure relate to a UE that receives a group RRC release message that is based on a group mobility configuration, the group RRC release message intended for communication to a group of multiple UEs. The UE can switch to a RRC inactive state based in part on a determination that a RRC connection suspend configuration directed to the UE is included in the group RRC release message. The UE can switch to a RRC idle state based in part on a determination that the RRC connection suspend configuration is not included in the group RRC release message. A network entity can generate the group RRC release message with the group mobility configuration, and the group RRC release message is intended for communication to the group of multiple UEs. The network entity can then transmit the group RRC release message to the group of multiple UEs.

Group-based connection release

A method and apparatus for hybrid automatic retransmission request (HARQ) is provided. The method is performed by a first UE. The method includes receiving, from a NodeB, an acknowledge configuration indicating an HARQ scheme of the first UE and uplink resource for the HARQ scheme; determining whether an acknowledgement for a data block associated with a first downlink control information (DCI) is to be transmitted according to the HARQ scheme.

Method and apparatus for hybrid automatic retransmission request

Apparatuses, methods, and systems are disclosed for transmitting message segments in parallel. One method includes segmenting a first PDCP layer SDU message into a plurality of first segments and transmitting a first set of segmented RRC messages to a second communication entity. The first method includes segmenting a second PDCP layer SDU message into a plurality of second segments and transmitting a second set of segmented RRC messages to the second communication entity in parallel with the first set of segmented RRC messages. Each of the segmented RRC messages includes one of the first or second segments and includes a procedure number that indicates to which procedure the included segment corresponds.

Parallel transmission of segmented RRC messages

Apparatuses, methods, and systems are disclosed for consecutive data packet feedback. One method includes receiving a first set of consecutive data packets. The method includes transmitting feedback corresponding to the first set of consecutive data packets, wherein the feedback comprises: an error indication in response each data packet in the first set of consecutive data packets failing to be received correctly; a non-error indication in response to at least one data packet in the first set of consecutive data packets being received correctly; a counter value that indicates a consecutive number of data packet failures; or some combination thereof.
