Embodiment Construction

[0017] The operating frequency bands for single carrier cellular operation are described below.

[0018] For LTE-based cellular networks, Rel-12 D2D-capable nodes or UEs can be designed to support any of the E-UTRA operating frequency bands listed in the table below.

[0019] Table 1 E-UTRA operating frequency band [3GPP TS 36.101, v12.3.0]

[0020]

[0021]

[0022]

[0023] The operating frequency bands for CA cellular operation are described below. In order for a D2D-enabled node or UE to support CA (Carrier Aggregation) on a combination of frequency bands, it is not enough for the D2D-enabled node or UE to support only each individual frequency band in the combination, instead it must also support specific additional RF requirements to determine the frequency band combination.

[0024] The following are Rel-12 D2D-capable nodes or UEs that can support intra-band continuous and non-continuous CA and operating band combinations for intra-band CA.

Abstract

A D2D-enabled node or user equipment UE (10) for a wireless communication network is disclosed, the D2D-enabled node or user equipment UE (10) being adapted to communicate to at least one other node (12, 100) (eg another A user equipment UE (12) or eNodeB (100)) indicates at least one unidirectional frequency capability of a node or user equipment UE (10) capable of implementing D2D. The unidirectional frequency capability may indicate a capability of supporting unidirectional D2D operation (ie, D2D transmission or D2D reception) on a specific frequency (frequency band). Related devices and methods are also disclosed.

Description

technical field [0001] The present disclosure relates to a D2D operation of a D2D-capable node or UE of a wireless communication network. Background technique [0002] The introduction of D2D capabilities into wireless communication technologies (eg the introduction of LTE Rel. 12) has presented new challenges regarding the use or sharing of resources between cellular and D2D operations. This is partly due to performing D2D operations using the same or similar carriers or frequency bands as cellular operations. In order to provide enough radio circuit resources to fully support simultaneous D2D operation and cellular operation (especially multi-carrier operation), a significant increase in the cost of a D2D-capable node may be required. Contents of the invention [0003] It is desirable to provide methods that allow the use of cellular operation as well as D2D operation with limited resource requirements. Accordingly, a method of managing or handling D2D operations and r...
