摘要： Uplink resources for semi-persistent channel state information (SP-CSI) reports and other uplink transport block transmissions may be managed. If resources allocated to the SP-CSI reports overlap, in time, with resources allocated to the uplink transport block transmissions, a determination of whether to drop an SP-CSI report may be made. Various selection criteria may be used to make this determination.

摘要： Embodiments of this application disclose a packet transmission method and a related apparatus. An access network device receives a first packet from an Internet-of-things (IoT) function network element; the access network device obtains first information, where the first information indicates that the first packet includes a passive or semi-active IoT instruction; and the access network device performs a passive or semi-active IoT operation based on the first packet. According to the foregoing method, the access network device learns that the packet from the IoT function network element is related to a passive or semi-active internet of things, and the access network device performs the passive or semi-active IoT operation based on the first packet. This resolves a packet transmission problem in a scenario in which a passive or semi-active IoT system is converged with a cellular network.

摘要： Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

摘要： According to an aspect, a wireless device sends, while in an RRC inactive state, a message requesting resumption of an RRC connected state. Upon sending the message, the wireless device starts a timer according to a predetermined value. While the timer is running, the wireless device attempts decryption and integrity check handling for packets subsequently received from the wireless network.

摘要： A method for operating a user equipment (UE) comprises receiving configuration information for a CSI report. The configuration information includes information to: configure a codebook and parameters for the codebook, the codebook comprising a precoding matrix indicator (PMI) indicating a set of components S to represent N3 precoding matrices, where N3≥1; and partition the PMI into two subsets, a first PMI subset indicating a first subset of components S1 from the set of components S, and a second PMI subset indicating a second subset of components S2 from the set of components S different from the first subset of components S1. The method further comprises determining the CSI report based on the configuration information, the CSI report including the second PMI subset indicating the second subset of components S2, and transmitting the determined CSI report over an uplink (UL) channel.

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.
