Methods and apparatuses are disclosed for network triggered service restoration (NTSR). According to an embodiment, a serving gateway (SGW) obtains, from a mobility management entity (MME), information capable of indicating whether to apply NTSR for a terminal device. In response to detecting a failure of the MME, the SGW determines whether to apply NTSR for the terminal device based on the obtained information.

A communication apparatus operable to communicate with a plurality of terminal stations capable of operating in a Doze state and in an Awake state in an IEEE 802.11ba standard, obtains, from each of the plurality of terminal stations, a value of a Transition delay indicating a time period required to switch from the Doze state to the Awake state, groups the plurality of terminal stations into a plurality of groups based on the value of each of the plurality of terminal stations, sets an order for transmitting the Wake-up frame for causing a transition from the Doze state to the Awake state for each of the plurality of groups, and transmits, according to the set order, the Wake-up frame to one or more terminal stations belonging to each of the plurality of groups.

A communications device including a receiver configured to receive signals from one or more of a plurality of other communications devices within sidelink communications resources of a plurality of instances of a resource pool of a sidelink interface, the resource pool being formed of a plurality of time-divided slots and a plurality of frequency-divided regions, and a controller. The controller is configured in combination with the receiver to monitor for one or more first current signals transmitted by at least a first transmitting communications device in a first subset of the time-divided slots and the frequency-divided regions of the resource pool during a first of the resource pool instances.

An STA MLD can receive traffic indication map (TIM) information from an access point (AP) MLD in a wireless local area network (LAN) system. The TIM information can include a TIM bitmap and a link bitmap. The TIM bitmap includes a bitmap related to whether data to be transmitted by the AP MLD to each receiving MLD is present, and the receiving MLD can include the STA MLD. The link bitmap can include information related to a link of the receiving MLD, in which the data to be transmitted by the AP MLD is present, from among the receiving MLDs. The STA MLD can receive wake-up link information from the AP MLD. The wake-up link information can include information related to a link to be woken up from among links of the STA MLD.

In an example, a User Equipment (UE) receives and/or detects a transmission of data from a network. The transmission of the data is addressed to a Group Radio Network Temporary Identifier (G-RNTI) for a Hybrid Automatic Repeat Request (HARQ) process. In response to receiving and/or detecting the transmission of the data, the UE (i) starts a first HARQ Round Trip Time (RTT) timer associated with the G-RNTI for the HARQ process, and (ii) starts a second HARQ RTT timer associated with a Cell Radio Network Temporary Identifier (C-RNTI) for the HARQ process. The UE starts a multicast retransmission timer for the HARQ process in response to expiry of the first HARQ RTT timer. The UE starts a unicast retransmission timer for the HARQ process in response to expiry of the second HARQ RTT timer. The UE receives and/or detects a first retransmission of the DL data addressed to the G-RNTI for the HARQ process. In response to receiving and/or detecting the first retransmission of the data, the UE (i) stops the multicast retransmission timer, and (ii) stops the unicast retransmission timer.

A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.

Apparatus, methods, and computer-readable media for autonomous physical uplink shared channel repetition cancellation for energy-limited devices are disclosed herein. A user equipment (UE) may transmit, to a base station, a plurality of uplink channel repetitions. The UE may determine that a device power level associated with the UE does not exceed a predetermined threshold that corresponds to a power requirement to transmit a number of uplink channel repetition instances in the plurality of uplink channel repetitions. The UE may determine to not transmit the number of uplink channel repetition instances based on the device power level falling below the predetermined threshold. The UE may modify the device power level through an energy harvesting operation. Thus, the power efficiency and reliability of uplink channel repetitions can be increased.

A discontinuous reception (DRX) parameter configuration method includes a first communication apparatus that sends data to a second communication apparatus on a sidelink based on a DRX parameter. The second communication apparatus determines an active time and a sleep period of the second communication apparatus based on the DRX parameter, and receives the data in the active time.

The present disclosure relates to a carrier information indication method and apparatus, a cell search method and apparatus, a base station, a user equipment and a computer-readable storage medium. The carrier information indication method includes setting independent machine-type communication (MTC) carrier information; and transmitting the independent MTC carrier information to a user equipment (UE). In the aspects of the disclosure, by means of setting independent MTC carrier information and transmitting the independent MTC carrier information to a UE, the UE does not need to search for an independent MTC carrier when searching for a cell, thereby saving on the electricity of the UE.

A method of wirelessly providing a multiplexed wake-up packet for waking up a plurality of wireless communication receivers from a low-power state to a normal state is provided. The multiplexed wake-up packet comprises a composite of individual wake-up packets, wherein each individual wake-up packet is addressed to one of the plurality of wireless communication receivers. The method comprises determining a number N of individual wake-up packets of the multiplexed wake-up packet, determining a time offset T.sub.o(n) for each of the individual wake-up packets, where n=1 . . . N, generating the multiplexed wake-up packet as a time domain multiplexed signal comprising all the N individual wake-up packets with the time offsets T.sub.o(n), and transmitting the multiplexed wake-up packet. A network node is arranged to perform the method.
