摘要： Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

摘要： An adaptive RACH operation is proposed for machine-type communications (MTC) in a 3GPP wireless network. The adaptive RACH operation is based on context information to reduce RACH collision probability, to control network overload, and to enhance system performance. The context information includes device related information and network related information. Device related information includes device type and service or application type. Network related information includes network load information and historical statistics information. Based on the context information, an MTC device adjusts various network access and RACH parameters by applying adaptive RACH operation in different levels. For example, in the application level and the network level, the MTC device adjusts its access probability or RACH backoff time for RACH access. In the radio access network (RAN) level, the MTC device adjusts its access probability or RACH backoff time, or transmits RACH preambles using adjusted RACH radio resources and preambles.

摘要： A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. In order to reduce the quantity of periodic SI broadcasting, on-demand SI delivery is enabled. With on-demand SI delivery, signaling overhead is proportional to the frequency of SI acquisition. From the network side, the base stations proactively provide SI delivery options and delivers SI over unicast or scheduled broadcast. From the UE side, UE determines how to acquire SI, i.e., by listening to broadcast or by sending an on-demand request via existing procedures such as a random-access procedure over a random-access channel (RACH).

摘要： A method of UE-initiated radio resource control, RRC, connection release procedure in LTE/5G network is proposed. A UE is required to establish RRC connection and enter RRC_Connected state for data communication (501). However, power consumption from functions for UE mobility can be significant, especially in RRC_Connected state. It is thus desirable for the UE to be able leave the RRC_Connected state (503, 504) by triggering an RRC connection release procedure (502). The triggering conditions may include: 1) UE has no data transmission for quite some time; 2) UE is in low battery status; 3) UE has incoming voice/video call from another USIM; or 4) UE has outgoing voice/video call in another USIM.

摘要： Aspects of the disclosure provide a method that includes receiving a measurement configuration message indicating a predetermined number. A measurement event is defined based on the predetermined number of signal beams from a serving base station and the predetermined number of signal beams from a neighboring base station. The method also includes identifying a first number of best signal beams from the serving base station and a second number of best signal beams from the neighboring base station, where the first number and the second number are equal to or less than the predetermined number. The method further includes determining whether the measurement event occurs based on the first number of best signal beams from the serving base station and the second number of best signal beams from the neighboring base station, and sending a measurement report when the measurement event occurs.

摘要： Apparatus and methods are provided to enhance BSR and LCP procedures for the dual connectivity system. In one novel aspect, the BSR is handled for each MAC entity according to one or more allocation rules. In one embodiment, the allocation rule is configured by the network. In another embodiment, the allocation rule is determined by the UE based on historic statics. In yet another embodiment, the allocation rule is determined by the UE based on information from the network. In one embodiment, the allocation rule indicates percentage of traffic allocated to each MAC entity. In another novel aspect, LCP is performed independently for each MAC entity if the split bearer is configured and the prioritized bit rate (PBR) and the bucket size duration (BSD) are signaled for each eNB. In one embodiment, separate sets of LCG variables are maintained independently for each MAC entity.

摘要： A method and apparatus for UE to report preference indication and other UE assistance information to the network is proposed. The UE transmits RRC release assistance information to the network. The assistance information is based on both cell change count and RRC state transition count so that RRC inactivity time can be determined to reduce signaling overhead.
