摘要： Example embodiments presented herein are directed towards a wireless terminal and base station, and corresponding methods therein, for providing a handover for a subset of bearers associated with the wireless terminal. The subset of bearers is less than a total number of bearers associated with the wireless terminal. Thus, upon the completion of the handover procedure, at least one bearer will stay connected with a source base station.

摘要： A radio access network (RAN) node, a wireless device and various methods are described herein for managing paging bandwidth. In one embodiment, the RAN node transmits a message (e.g., paging message, assignment message) to wireless devices, where the message comprises at least the following: (i) a page mode field which includes information indicating one or more coverage classes for which one or more paging messages were available for transmission during a time interval but were not transmitted to a plurality of wireless devices; and (ii) a used_downlink_coverage_class field which includes information indicating a coverage class associated with the transmitted message.

摘要： A method performed by a radio access network node for paging of a communication device in a coverage area, served by the radio access network node, in a communications network, the method comprising: receiving (401) a page request from a core network node, wherein the page request comprises an indication of a support level of the communication device (140), which support level indicates whether or not the communication device (140) supports a specific mode of operation of a RAT; and determining (402), based on the indication of the support level of the communication device, and based on a capability of the coverage area to support the specific mode of operation of the RAT, a channel for paging the communication device in the coverage area, or not to page the communication device in the coverage area.

摘要： An example method in a user equipment comprises generating a random access preamble signal and transmitting the random access preamble signal. This generating of the random access preamble signal comprises generating a Single-Carrier Frequency-Division Multiple Access (SC-FDMA) random access preamble signal comprising two or more consecutive preamble symbol groups, each preamble symbol group comprising a cyclic prefix portion and a plurality of identical symbols occupying a single subcarrier of the SC-FDMA random access preamble signal. The single subcarrier for at least one of the preamble symbol groups corresponds to a first subcarrier frequency and the single subcarrier for an immediately subsequent one of the preamble symbol groups corresponds to a second subcarrier frequency.

摘要： A user equipment (400) comprising a narrowband receiver (12) is configured to search among different possible narrowband allocations (16) for a narrowband carrier (14) having a specific characteristic. The narrowband receiver (12) in particular is configured to search a wideband frequency grid for a narrowband portion of a wideband carrier (20) that the narrowband carrier (14) is permitted to lie in-band with or adjacent to, to obtain one or more candidate wideband gridpoints (18). The narrowband receiver (12) prioritizes one or more of the possible narrowband allocations (16) based on their proximity to the one or more candidate wideband gridpoints (18). The narrowband receiver (12) then searches among the different possible narrowband allocations (16) for the narrowband carrier (14) having the specific characteristic, based on the specific characteristic and that prioritization.

摘要： The network node of a cellular network assigns a first part of a shared radio resource to a first User Equipment, UE, for uplink transmissions in the cell, and instructs the first UE to apply a first UE-specific Hybrid Automatic Repeat Request, HARQ, process for transmitting on the assigned first part. The network node also assigns a second part of the shared radio resource to a second UE for uplink transmissions in the cell, and instructs the second UE to apply a second UE-specific HARQ process for transmitting on the assigned second part, the second HARQ process being separate from the first HARQ process. The network node then receives data transmitted from the first UE on the assigned first part based on the first HARQ process and data transmitted from the second UE on the assigned second part based on the second HARQ process.

摘要： Systems and methods relating to a narrowband Primary Synchronization Signal (NB-PSS) and a narrowband Secondary Synchronization Signal (NB-SSS) are disclosed. In some embodiments, a base station in a wireless network comprises a processor and storage that stores instructions executable by the processor whereby the base station is operable to transmit a NB-PSS and a NB-SSS in a narrowband portion of a downlink system bandwidth. The NB-PSS and the NB-SSS are transmitted such that more than two occurrences of the NB-PSS and more than two occurrences of the NB-SSS are transmitted over a defined time interval, each occurrence of the NB-PSS is transmitted over multiple contiguous Orthogonal Frequency Division Multiplexing (OFDM) symbols and each occurrence of the NB-SSS is transmitted over multiple contiguous OFDM symbols, and each occurrence of the NB-SSS provides an indication of a location of the occurrence of the NB-SSS within the defined time interval.

摘要： A method in a first base station for determining a spectrum allocation to be used by the first base station in a wireless network is provided. The wireless network is dedicated a spectrum S. The first base station is associated with a first operator. The first base station detects (403) a number N of second signals. Each second signal is transmitted by a respective second base station to announce its intended use of said spectrum at a time t. Each second base station is associated with a respective second operator or the first operator. The first base station then determines (404) the spectrum allocation to be used by the first base station at the time t as a subset of the spectrum S. The subset of the spectrum S is a function of N.

摘要： A method in a node is disclosed. The method comprises receiving a signal, and obtaining a first oversampled received signal by sampling the received signal according to a symbol rate. The method further comprises estimating a first frequency offset based on the first oversampled received signal, the first frequency offset estimated using an estimation range limited to one of a bandwidth of the received signal or the symbol rate of the received signal, and obtaining a second oversampled received signal by sampling the received signal according to N times the symbol rate, wherein N is greater than 1. The method further comprises estimating a true frequency offset based on the first frequency offset estimate and the second oversampled received signal.
