摘要： Embodiments include methods performed by a wireless device for random access to a wireless communications network. Such methods include transmitting a random access preamble in a first uplink (UL) bandwidth part (BWP) of a carrier and selecting a first downlink (DL) BWP of the carrier based on an association between the first UL BWP and the first DL BWP. Such methods include monitoring the first DL BWP for a random access response from the wireless communication network to the transmitted random access preamble. Other embodiments include complementary methods for a base station configured to support random access by wireless devices, as well as wireless devices and base stations configured to perform such methods.

摘要： One aspect of the disclosure provides a method for a terminal device in a wireless communications network, wherein the terminal device is configurable with a plurality of logical channel groups. The method comprises generating buffer status information and transmitting a message to a network node operative in the wireless communications network. The message comprises a buffer status report comprising the buffer status information. The buffer status report comprises respective indications, for each of the plurality of logical channel groups, of the availability of data to transmit in the terminal device for the logical channel group. The buffer status report further comprises respective buffer size fields, for one or more of the logical channel groups for which data is available to transmit, indicating an amount of data which is available to transmit.

摘要： Embodiments described herein provide methods and apparatus for performing a random access procedure to access a wireless communications network. A method in a wireless device comprises responsive to transmitting a first random access preamble to a base station using first random access resources in an uplink, UL, bandwidth part, BWP, of a carrier: selecting, based on an association, a first downlink, DL, BWP of the carrier, wherein the association maps a plurality of DL BWPs of the carrier to different values of a parameter related to physical random access configurations and/or to different UL BWPs of the carrier; and monitoring the first DL BWP in order to receive a random access response from the base station.

摘要： The present disclosure relates generally to wireless devices (e.g., Internet of Things (IoT) devices) and, more particularly, to improving the capacity of a logical channel such as the Random Access Channel (RACH) to cater to wireless traffic (e.g., IoT traffic). In one embodiment, a wireless device, when deciding to attempt a system access in accordance with the present disclosure, would first select a Training Sequence Code (TSC) based on the device's coverage class and then transmit one or more access request bursts (each including the selected TSC) on a logical channel to a wireless access node.

摘要： Exemplary embodiments include methods for paging of a communication device in a coverage area served by a radio access network (RAN) node. Such embodiments include receiving, from a core network node, an indication of which of the following modes of operation are supported by the communication device: Extended-Coverage Global System for Mobile communications Internet of Things (EC-GSM-IoT) mode; and General Packet Radio Services (GPRS) and/or Enhanced GPRS (EGPRS) mode. Embodiments also include, based on the indication and on a capability of the coverage area to support said following modes of operation, determining at least one of the following: whether to page the communication device in the coverage area; and a channel for paging the communication device in the coverage area. Other embodiments include complementary methods performed by a core network node, as well as RAN nodes and core network nodes configured to perform any of the exemplary methods.

摘要： A radio access network node (e.g., base station system), a mobile station, and various methods are described herein that increase the size and/or efficiency of an ack/nack bitmap in one or more control messages (e.g., Packet Downlink Ack/Nack message(s)). The mobile station when operating in a Downlink Multi Carrier mode sends the one or more control messages to the radio access network node.
