Embodiment

[0174] According to some embodiments, a method for configuring beamforming paging transmissions to a UE comprises the steps of:

[0175] Configure paging occasions and configure [multiple beamforming] paging transmissions per 1 paging occasion,

[0176] taking into account the capabilities of the UE when configuring paging occasions and / or paging transmissions within each paging occasion,

[0177] Optionally, [at least some] paging occasions coincide with [or overlap] with SS block beam scanning [forming SS burst sets]

[0178] {This should not rule out that paging occasions may not coincide with SS block beam scan},

[0179] Optionally, the capabilities of the UE include the maximum receive bandwidth of the UE [for example, whether the UE is a narrowband UE or a wideband UE],

[0180] • Optionally, POs are placed differently in the time domain [vs. SS block beam scan / SS burst set] depending on UE capabilities. {This pseudo-claim is intended to support moving the PO to imme...

Abstract

According to certain embodiments, a method performed by a network node is provided for configuring beamformed paging transmissions to user equipment (UE). The method includes obtaining information identifying at least one capability of the UE and taking into account the at least one capability of the UE when configuring at least one of the at least one paging occasion and the at least one paging transmission within each paging occasion.

Description

Background technique [0001] An important property of upcoming 5G systems such as NR is the use of high carrier frequencies, such as those in the 6-100GHz range. For such a high frequency spectrum, the atmospheric, penetration and diffraction attenuation properties may be much worse than for the lower frequency spectrum. In addition, receiver antenna aperture, which is a measure describing the effective receiver antenna area to collect electromagnetic energy from incoming electromagnetic waves, is inversely proportional to frequency. For example, if omnidirectional receive and transmit antennas are used, the link budget will be worse for the same link distance even in a free-space scenario. This motivates the use of beamforming to compensate for the loss of link budget in the high frequency spectrum. This is especially important when communicating with user equipment (UE) with poor receivers (eg, low cost / low complexity UEs). Other means to improve the link budget include re...
