Abstract:
Systems and methods relating to reconfiguration of a Carrier Aggregation (CA) enabled wireless device using a measurement gap are disclosed. In some embodiments, a method of operation of a CA enabled wireless device in a cellular communications network comprises reconfiguring the wireless device during a measurement gap such that the wireless device is enabled to receive a first set of one or more carriers after the measurement gap that are different than a second set of one or more carriers that the wireless device was receiving before the measurement gap. In some embodiments, the reconfiguration of the wireless device during the measurement gap enables reconfiguration of the wireless device for measurements on a Secondary Component Carrier (SCC) of a configured and deactivated Secondary Cell (SCell) of the wireless device without serving cell interruption.
Abstract:
A network node that serves a host cell in a cellular communication system transmits, at (a) first time interval(s), first control channel information on a control channel that extends over a first bandwidth of a radiofrequency spectrum. The first control channel communicates information necessary to enable a first type of communication device to receive data from the host cell. The first type of communication device can receive first bandwidth-wide signals. At (a) second time interval(s), second control channel information is transmitted on a second control channel of a first M-cell. The second control channel occupies a second bandwidth that is smaller than the first bandwidth. The second time interval(s) do(es) not coincide with any of the first time interval(s). A second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device is thereby made capable of being served by the node.

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration (18210). The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing, OFDM transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology (18220). Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed. (Figure 8)

Metode şi dispozitive într-o comunicaţie fără fir de generaţia a cincea, un exemplu al unei astfel de metode include recepţionarea unui semnal pe legătura descendentă cuprinzând un indice de configurare acces pe legătura ascendentă, utilizarea indicelui de configurare acces pe legătura ascendentă pentru a identifica o configuraţie de acces pe legătura ascendentă dintr-o multitudine predeterminată de configuraţii de acces pe legătura ascendentăşi transmiterea către reţeaua de comunicaţii fără fir în conformitate cu configuraţie de acces pe legătura ascendentă identificată. Metoda include, de asemenea, recepţionarea, într-un prim sub-cadru al legăturii descendente, a unei prime transmisii OFDM formatată în conformitate cu o primă numerologie şi recepţionarea, într-un al doilea sub-cadru al legăturii descendente, a unei a doua transmisii OFDM formatată în conformitate cu o a doua numerologie, a doua numerologie diferind de prima numerologie. Prima numerologie are o primă distanţare a sub-purtătoarelor, iar cea de-a doua numerologie are o a doua distanţare a sub-purtătoarelor, unde prima distanţare a sub-purtătoarelor fiind diferită de a doua distanţare a sub-purtătoarelor. Sunt prezentate, de asemenea, variante ale acestei metode, aparate corespunzătoare,metode şi aparate corespunzătoare din reţea.
