Disclosed are methods for a random access. One embodiment of the subject application provides a method performed by a gNB, including determining a user equipment (UE) to enter an RRC_INACTIVE state by a gNB central unit (gNB-CU), sending a UE context suspension indication and a UE identification (ID) of small data transmission (SDT) to at least one first gNB distributed unit (gNB-DU) by the gNB-CU, storing the UE ID of SDT and keeping a UE context of SDT by the at least one first gNB-DU, and treating the UE in the RRC_INACTIVE state and forwarding a radio resource control (RRC) release manage to the UE by the at least one first gNB-DU, wherein the UE context suspension indication is for indicating the at least one first gNB-DU to keep a the UE context of SDT in the RRC_INACTIVE state, and the UE ID of SDT is for identifying the UE context of SDT. Related apparatuses are also disclosed.

Methods and apparatuses for small data transmission

The subject application relates to method and apparatus of group-based resource allocation. A method performed by a first Base station (BS), comprises: transmitting a scheduling user equipment (S-UE) qualification criterion to a group of UEs; receiving at least one request for being a first S-UE from at least one member UE (M-UE) in the group that satisfies the S-UE qualification criterion; transmitting a signal indicating the first S-UE based on the at least one request; and transmitting, to the first S-UE, group-based resource information for the group of UEs.

Method and apparatus of group-based resource allocation

Embodiments of the present application are directed to a method and apparatus for sidelink DRX operation. An exemplary method may include: configuring DRX information for sidelink, wherein the DRX information includes a value of DRX on-duration timer, a DRX cycle, and at least one DRX offset value; and starting the DRX on-duration timer from a beginning position based on the DRX cycle and the DRX offset value.

Embodiments of the present application relate to a method and apparatus for data transmission. An exemplary method includes: receiving a data transmission request from a first base station, in a second base station, wherein the data transmission request indicates data transmission information on a data transmission; determining whether to transmit the data transmission by the second base station or make an anchor relocation for the data transmission based on the data transmission information and assistant information associated with the data transmission; and transmitting a data transmission response to the first base station based on the determining.

Method and apparatus for data transmission

Embodiments of the present application relate to a method and an apparatus for or small data transmission of a user equipment (UE) in an RRC_IDLE state or an RRC_INACTIVE state. According to an embodiment of the present application, a method can include: a method may include maintaining a priority variable for each logical channel of at least one logical channel; determining a value of the priority variable for each logical channel after performing a first logical channel prioritization (LCP) procedure; receiving a message indicating a MAC reset; and after receiving the message, in a second LCP procedure subsequent to the first LCP procedure, using the value as an initial value of the priority variable for each logical channel of the at least one logical channel. Embodiments of the present application can satisfy the QoS requirement and fairness for the traffics transmitted in the logical channels in NR systems.

Method and apparatus for small data transmission

Embodiments of the present application are directed to a method and apparatus for restricting access of devices. The receiving cell access related method may include: receiving cell access related information; and information performing an access control based on the cell access related information and a device type of a user equipment (UE).

Method and apparatus for restricting access of devices

Embodiments of the present disclosure relate to methods and apparatuses for absence time request and user equipment (UE) behavior during the absence time. According to an embodiment of the present disclosure, a method performed by a UE for wireless communication includes: transmitting a request for an absence time to a base station (BS); receiving a response assigning the absence time from the BS; suspending a connection to the BS upon receiving the response; and resuming the connection to the BS before or at the end of the absence time.

Method and apparatus for absence time request

The present application relates to a method and apparatus for aligning sidelink DRX configuration. One embodiment of the subject application provides a method for sidelink communication, comprising: receiving, from a second User Equipment (UE), a second request for one or more sidelink Discontinuous Reception (DRX) configurations, wherein the second request includes assisting information; and transmitting, by the first UE, the one or more sidelink DRX configurations determined based on the assisting information to the second UE.

Method and apparatus for aligning sidelink DRX configuration

Embodiments of the present application are directed to a method and apparatus for timely scheduling. The method may include: configuring DRX configuration information; and preventing a MAC entity from entering into inactive time in response to that a first MAC PDU is not transmitted in an uplink grant.
