Problems solved by technology

Spectrum sharing between existing and new RANs offers certain advantages, but in the case of spectrum sharing between NR and fourth generation (4G) RAN using the Long Term Evolution (LTE) air interface, there is a lack of support for spectrum sharing. The realization of the layout requires a lot more work

Embodiment Construction

[0029] Spectrum sharing allows operators to use existing long-term evolution (LTE) conventional spectrum for the fifth generation (5G) radio (NR) service without obtaining the initial cost of new 5G NR spectrum or 5G radio and baseband hardware. In addition to shared LTE and NR operations in a single frequency band, the operator also expresses interests for shared operations of NR bands, which spans more than one LTE band.

[0030] By flexible allocation of NR and LTE control channels and signals, and surrounding public reference signals (CRS) and synchronization signals (eg, the primary synchronization signal (PSS), auxiliary signal (SSS), a secondary signal (SSS), a secondary signal (SSS), and a public broadcast channel ( PBCH) Signal) The rate matching, the spectrum in the shared frequency band between the LTE and NR transmission is possible.

[0031]The rate matching is described in Section 5.1.4.1 and 5.1.4.2 of 3GPP TS 38.214V15.3.0. In short, an example of a rate match rela...

Abstract

Regarding a first radio frequency (RF) carrier, a network node of a wireless communication network configures two or more bandwidth parts (BWPs) in the first RF carrier, each BWP aligning with a respective one of two or more other RF carriers positioned within the RF spectrum spanned by the first RF carrier. The node determines a frequency-sharing configuration for each BWP, in dependence on radio resource usage of the respective other RF carrier and configures wireless communication devices to use respective ones of the BWPs. For example, the node determines a resource-usage pattern for control-related signaling conveyed on the other RF carriers and transmits rate-matching information for the BWPs of the first RF carrier. Each BWP occupies RF spectrum used by a respective one of the other RF carriers, and the rate-matching information transmitted for each BWP depends on the resource-usage pattern determined for the respective other RF carrier.

Description

Technical field [0001] The present disclosure generally relates to the field of wireless network communication, and more particularly to network nodes involving dynamic spectrum sharing (DSS) allocated by a bandwidth portion (BWP). Background technique [0002] Key Challenges appear in the context of deploying new wireless communication technologies (eg, based on the fifth generation (5 g) radio access network (RAN)). RANs configured for 5G operations use a air interface called new radio (NR). The existing RAN and new RAN spectral sharing provide some advantages, but in the case of NR and the spectrum sharing between the fourth generation (4G) RAN using long-term evolution (LTE) air interface, the lack of spectrum sharing The implementation of the arrangement requires a lot of more work. Inventive content [0003] One or more embodiments of the present invention relate to a first RF carrier spanning an RF spectrum comprising two or more other radio frequency (RF) carriers. Speci...
