摘要： This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

摘要： Wireless communications systems and methods related to network power saving are provided. In one embodiment, a base station (BS) of a wireless communication network determines to enter a sleep mode. The BS transmits, to one or more user equipment (UEs) of the wireless communication network, a communication signal indicating that the BS will enter the sleep mode. The BS operates in the sleep mode for a sleep mode period. In one embodiment, a UE receives, from a BS, a communication signal indicating that the BS will enter a sleep mode for a sleep mode period. The UE refrains, during one or more sleep windows of the sleep mode period, from performing uplink communications.

摘要： A first access node receives, from a second access node, at least one message comprising configuration parameters of a first cell of a third access node. The third access node is a child node associated with the second access node. The third access node communicates with the second access node via at least one backhaul link. The configuration parameters comprise an identifier indicating the first cell and backhaul information of the at least one backhaul link. The first access node determines, based on the backhaul information, a handover of a wireless device to the first cell. The first access node transmits, to the second access node, a message requesting the handover of the wireless device to the first cell.

摘要： Technology for a user equipment (UE) operable to decode a resource mapping pattern of a phase tracking reference signal (PT-RS) received from a base station in a wireless network is disclosed. The UE can decode control signaling received in a downlink from the base station. The control signaling can indicate a resource mapping pattern for a PT-RS. The UE can identify the resource mapping pattern for the PT-RS based on the control signaling received from the base station. The UE can encode one or more PT-RS for transmission to the base station in an uplink in accordance with the resource mapping pattern for the PT-RS.

摘要： A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to receive a higher layer signalling to configure the UE with a code block group (CBG). The instructions are also executable to receive one or more downlink (DL) transmissions. Hybrid automatic repeat request acknowledgement (HARQ-ACK) of the one or more DL transmissions are multiplexed and reported in a single uplink (UL) reporting. The instructions are also executable to generate a HARQ-ACK codebook comprises a first HARQ-ACK sub-codebook and a second HARQ-ACK sub-codebook.

摘要： Apparatus and methods are provided to support dual active protocol stacks (DAPS) to reduce mobility interruption time in both LTE and NR system. In novel aspect, the PDCP reconfiguration includes reconfiguring a normal PDCP to an DAPS PDCP for DAPS such that the DAPS PDCP is associated with both the source cell and the target cell, and reconfiguring an DAPS PDCP to the a normal PDCP by releasing the association with the source cell. In one embodiment, the PDCP entity receives a PDCP reconfiguration request from upper layers of the UE configured with DAPS establishes a header compression protocol, a ciphering function, and an integrity protection function for the target cell. In one embodiment, the PDCP reconfiguration request triggers the DAPS PDCP to be released. The DAPS PDCP resets and releases the source header compression, ciphering and integrity protection functions.
