摘要： Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that improve data packet exchange between a UE in an inactive mode and a network. In certain configurations, the apparatus may receive, from a user equipment (UE) in an active mode, a first packet including a first identifier associated with an anchor base station, a second identifier associated with a UE context, and a payload. The apparatus may identify the anchor base station based at least in part on one or more of the first identifier associated with the anchor base station or the second identifier associated with the UE context. The apparatus may transmit a second packet to the anchor base station. The second packet may include at least a portion of the first packet.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for enabling access control in a connected mode, idle mode, and an inactive state. An exemplary method generally includes receiving access control information associated with one or more services used by the UE for communicating with the wireless communications network, receiving a request to transmit traffic using the one or more services, checking a type of the traffic against the access control information, and scheduling the traffic for transmission if the type of the traffic satisfies one or more criteria in the access control information based on the checking.

摘要： The invention concerns a method and an apparatus implementing the method. In the method is received a neighbor cell relation list and a request to report new cells not included in the neighbor cell relation list to the mobile node to a mobile node. The mobile node detects at least one new cell not included in the neighbor cell relation list and stores information regarding the at least one new cell not included in the neighbor cell relation list in a memory. The mobile node determines whether a threshold number of new cells not included in the neighbor cell relation list have been stored in the memory of the mobile node. In response to reaching the threshold number, the mobile node preparing for transmitting the information regarding the at least one new cell not included in the neighbor cell relation list to a radio network node.

摘要： Systems and techniques for management of network resource access attempts. In response to identifying that a radio bearer has failed, a radio resource associated with the radio bearer is released, either through request by a user equipment or direction by the network. Attempts at regaining access to the released radio bearer are inhibited during conditions recognized as potentially leading to excessively frequent unsuccessful attempts. Inhibition of attempts at regaining access to the released radio bearer may comprise imposing a backoff timer to inhibit reestablishing access to the released radio link for the duration specified by the backoff timer.

摘要： In a wireless communications network, a user equipment is capable of operating in a first mode in which uplink signals are transmitted using a single antenna and in at least a second mode in which uplink signals are transmitted using two or more antennas. It is determined at the user equipment whether to request activation of the first or second mode and a first message is sent to a network node requesting activation of the first or second mode together with Medium Access Control (MAC) Scheduling Information (SI). Alternatively, the user equipment sends, to the network node, an indication of a threshold for use in determining whether to activate the first or second mode together with user equipment capability information. A second message is received at the user equipment from the network node indicating whether the first or second mode should be activated.

摘要： A wireless transmitter transmits a plurality of data blocks defined in a transmission window for receipt by a receiver. The transmitter transmits a status request to the receiver for positive acknowledgement of successful receipt of the status request, the status request identifying a data block. The transmitter updates the transmission window upon receipt of a positive acknowledgement of receipt of a data block or upon receipt of a positive acknowledgement of receipt of a status request relating to a data block. The updating removes the record of the data block from the transmission window and adds a record of at least one different data block to the transmission window.
