A method to reduce signaling interaction in an access process of a terminal includes: receiving, by a convergent network device, an access request message from a first access device on a first network, where the access request message carries a first globally unique temporary identity (GUTI) of a terminal, which is an old GUTI on the first network or a GUTI on the first network and obtained by mapping a second GUTI on a second network; determining, by the convergent network device, a first target context of the terminal on the first network based on the first GUTI and a device identifier corresponding to the convergent network device when serving as a mobility management device; and sending, by the convergent network device, an access response message to the first access device to indicate that the terminal has successfully accessed the first network.

A wireless access node serves wireless User Equipment (UEs) and wireless Integrated Access and Backhaul Mobile Terminations (IAB MTs). A radio exchanges access communications with the UEs over a frequency channel. The radio receives an IAB request from one of the IAB MTs, and in response, a controller allocates the frequency channel into a UE subchannel and an MT subchannel. The radio now exchanges access communications with the UEs over the UE subchannel and exchanges backhaul communications with the wireless IAB MT over the MT subchannel. The controller reallocates the frequency channel when an IAB MT is added to give the new IAB MT its own MT subchannel. The controller reallocates the frequency channel when an IAB MT is removed to increase the size of the UE subchannel.

A wireless communication network serves user communication devices using Internet Protocol (IP) and Integrated Access and Backhaul (IAB). An IAB Mobile Termination (MT) and an IAB donor establish a wireless IAB link. The IAB MT and a Centralized Unit (CU) establish IP links over the wireless IAB link. The IP links have different QoS levels. The IAB MT exchanges data streams with the user communication devices. The data streams have different QoS requirements. The IAB MT and the CU correlate the QoS requirements of the data streams with the QoS levels of the IP links. The IAB MT and the CU exchange individual ones of the data streams over individual ones of the IP links based on the QoS correlations. The CU exchanges the data streams with a data communication network based on the QoS requirements.

Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a base station of a wireless communications system to determine a configuration for a repeating device to forward signals to another device. In some examples, the configuration may be based on a number of repeating devices in the wireless communications system. The base station may also transmit a message for the repeating device to forward. In some examples, based on a buffering capability of the repeating device, the base station may transmit the message with a zero time offset relative to the control signaling. The repeating device may receive and process the control signaling and receive and buffer the message. In response to processing the control signaling, the repeating device may transmit the buffered message to another device. Implementing aspects of present disclosure may enable an increased efficiency of forwarding in wireless communications systems.

A wireless access node controls Discontinuous Reception (DRX) for User Equipment (UEs). The wireless access node exchanges user data with network elements over backhaul links and determines backhaul link performance. The wireless access node selects DRX schedules for the UEs based on the backhaul link performance and transfers the DRX schedules to the UEs. The UEs power their wireless receivers per their DRX schedules. The wireless access node transfers data notices to the UEs per the DRX schedules. The UEs wirelessly receive the data notices per their DRX schedules. The wireless access node transfers user data to the UEs per the DRX schedules and the data notices. The UEs wirelessly receive the user data per the DRX schedules and the data notices.

A method for restoring a wireless backhaul link includes: measuring the signal quality of a first wireless backhaul link between a first new radio (NR) host station being accessed by a NR wireless backhaul base station and the NR wireless backhaul base station; in a case that the signal quality of the first wireless backhaul link is less than a link reselection threshold corresponding to the NR wireless backhaul base station, beginning a new search for an adjacent NR host station; measuring signal quality of a second wireless backhaul link between the NR wireless backhaul base station and a second NR donor base station; and initiating, when the signal quality of the second wireless backhaul link being greater than a first threshold continues a duration exceeding a first time length, a random access request to the second NR donor base station, so as to establish a wireless backhaul link with the second NR donor base station.
