That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
  • a UE may suffer from link performance drop, limited delivery range, and battery power drain as described above.
  • these issues come from the fact that the transmitter emissions or receiver blocking requirements are defined according to the assumption of non-co-located deployments between operators in adjacent spectrum (i.e., BS sites of different operators are not assumed to be co-located or shared in the same location) , and the need to protect adjacent operator deployments from unacceptable interference.
  • these interference issues may not exist to the same degree in different scenarios of adjacent operator deployment (e.g., the scenario where BS sites deployed by operators of adjacent spectrum are collocated/shared) .
  • the present disclosure proposes a number of schemes pertaining to relaxation in transmitter emissions or receiver blocking requirements.
  • the network node e.g., BS
  • the UE may apply relaxed transmitter emissions requirements for an UL transmission (optionally, the relaxed transmitter emissions requirements may be associated to tighter/decreased MPR requirements to increase maximum output power level) , or apply relaxed receiver blocking requirements for a DL reception.
  • the UE may transmit capability information to the network node, wherein the capability information indicates that the UE supports the relaxation in the transmitter emissions requirements and optionally the corresponding ability to tighten MPR requirements and increase in maximum transmitted output power level, or supports the relaxation in the receiver blocking requirements.
  • the transmitter emissions requirements may include the out-of-band emission requirements and/or the spurious emission requirements that are defined in 3GPP standards (e.g., 3GPP technical specification (TS) 38.101-1) .
  • the receiver blocking requirements may include the out-of-band blocking requirements and/or the adjacent channel selectivity (ACS) requirements that are defined in 3GPP standards (e.g., 3GPP TS 38.101-1) .
  • ACS adjacent channel selectivity
  • the UE may decrease the MPR for UL transmissions (e.g., based on the relaxed transmitter emissions requirements) and therefore increase its maximum transmitted power level.
  • the UE may increase the required utilized spectrum within an operating channel of the UE (e.g., based on the relaxed receiver blocking requirements) .
  • the same level of output power reduction is not required for the UE, and the UL data rate and coverage for the UE can be improved (e.g. depending on the modulation scheme and waveform, a UE operating in the edge resource blocks (RBs) may have an improved UL performance by up to 1.5dB if the MPR was able to be tightened/decreased) .
  • the power consumption of the UE may be reduced for the same coverage and link performance.
  • the proposed schemes of the present disclosure are applicable for the scenario of co-located adjacent operator deployment, as well as the scenario where the operator’s operating spectrum block is wider than the UE’s allocated spectrum block, but the present disclosure is not limited thereto.
  • the proposed schemes of the present disclosure may also be applicable for the scenario of non-co-located adjacent operator deployment or in the case of a Non- Terrestrial Network deployment where near-far interference effects are less of an issue when compared to terrestrial deployments (due to the distance between UE and satellite) , and where spectrum may be partitioned even by the same operator (e.g. frequency reuse factor > 1) .
  • FIG. 2 illustrates an example scenario 200 of co-located adjacent operator deployment in accordance with an implementation of the present disclosure.
  • Scenario 200 involves two networks of different MNOs (denoted as Operator A and Operator B) in adjacent operating channels, and the radio access network (RAN) site is shared between the MNOs (i.e., the BSs of different MNOs are co-located) .
  • MNOs multiple networks of different MNOs
  • RAN site acquisition is a major cost factor, and this has led to initiatives such as selective site sharing among MNO competitors, e.g., in rural and suburban areas. This trend is expected to grow further in the future, possibly with whole RAN infrastructure being shared between MNO competitors.
  • FIG. 3 illustrates an example scenario 300 of operator spectrum block wider than UE spectrum block in accordance with an implementation of the present disclosure.
  • Scenario 300 involves an MNO holding the license for a wider spectrum block than the spectrum block allocated to a UE, and the MNO operates the whole spectrum block from the same network site.
  • relaxation in transmitter emissions requirements and/or receiver blocking requirements may be applied for the UE outside of the allocated spectrum block, since the adjacent spectrum is still within the overall block used by the same operator.
  • FIG. 4 illustrates an example scenario 400 of existing out-of-band and spurious emissions requirements in current 3GPP standards.
  • Scenario 400 depicts the existing out-of-band and spurious emissions requirements for 3GPP NR UE operating in a 20MHz channel bandwidth, with the aforementioned parameters being defined symmetrically relative to the lower edge and the upper edge of the “channel bandwidth” allocated to the UE.
  • ACLR is the ratio of the filtered mean power centered on the assigned channel frequency to the filtered mean power centered on an adjacent channel frequency.
  • the spectrum emission mask of the UE applies to frequencies ( ⁇ f OOB ) starting from the ⁇ edge of the assigned NR channel bandwidth. For frequencies offset greater than ⁇ f OOB , the spurious emission requirements in clause 6.5.3 of TS 38.101-1 are applicable.
  • the out-of-band emission requirements lead to the permitted use of MPR by the UE, whereby the UE is permitted to reduce its maximum transmission power, when operating in certain uplink frequency resources (e.g., resource blocks (RBs) ) , to allow the UE to achieve the out-of-band emission requirements such as ACLR and SEM (i.e., the out-of-band emission requirements are associated with SEM and ACLR) .
  • uplink frequency resources e.g., resource blocks (RBs)
  • SEM i.e., the out-of-band emission requirements are associated with SEM and ACLR
  • TS 38.101-1 e.g., Table 6.2.2-1: MPR for power class 3
  • it is shown that higher MPR is allowed towards the edge frequency resources (e.g., RBs) of the UL operating channel.
  • ACS is a measure of a receiver's ability to receive an NR signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the center frequency of the assigned channel. Specifically, ACS is the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel (s) .
  • a virtual channel bandwidth may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE.
  • This channel bandwidth is virtual because the UE may not have the capability to actually transmit on such a wide channel bandwidth (i.e., the virtual channel bandwidth is larger than the maximum channel bandwidth supported by the UE) .
  • the virtual channel bandwidth is defined for the purpose of establishing the reference and boundary for out-of-band emission requirements and spurious emissions, which is more relaxed than if it was applied to the 20MHz channel bandwidth directly.

  • Scenario 500 depicts a 20MHz channel bandwidth being contained within a 40MHz virtual channel bandwidth.
  • the network may transmit a configuration to the UE to indicate the 40MHz virtual channel bandwidth and the center frequency of the virtual channel bandwidth, even though the UE would actually only transmit across a maximum of 20MHz channel bandwidth.
  • this configuration creates a 10MHz gap at both sides of the actually used 20MHz channel bandwidth.
  • the created gaps leave more margin for the UE to perform UL transmission with higher power (i.e., the MPR is tightened/decreased compared to nominal standardized values) , while applying the out-of-band emission requirements and the spurious emission requirements with a 10MHz shift and with the out-of-band emission requirements scaling according to a 40MHz channel bandwidth reference.
  • the center point of the virtual bandwidth may not be equal to the center point of the channel bandwidth, hence leaving different and possibly asymmetrical gaps at each side of the UE channel bandwidth.
  • the virtual channel relaxation scheme may also be applied in the out-of-band blocking and/or ACS requirements to create a similar gap at both sides of the actually used 20MHz channel bandwidth, such that the UE may perform DL reception with more required utilized spectrum (e.g., orthogonal frequency-division multiplexing (OFDM) subcarriers) within the UE’s operating channel, compared to nominal standardized values.
  • OFDM orthogonal frequency-division multiplexing
  • a frequency-shifted out-of-band/spurious emission requirements may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE.
  • This proposed scheme is similar to the first proposed scheme (i.e., using a virtual channel bandwidth) , in that it is defined for the purpose of establishing the reference and boundary for out-of-band emission requirements and spurious emissions, which is more relaxed than if it was applied to the 20MHz channel bandwidth directly.
  • the out-of-band emission requirements are defined with respect to the channel bandwidth actually used by the UE.
  • Scenario 600 depicts a 20MHz channel bandwidth with the reference and boundary of the out-of-band emission requirements shifted by 10MHz away from the channel edge.
  • the network may transmit a configuration to the UE to indicate the frequency-shifted out-of-band/spurious emission requirements (i.e., to indicate a frequency shift at one or both edges of a channel bandwidth of the UE for the transmitter emissions requirements and/or the receiver blocking requirements) .
  • This configuration creates a 10MHz gap at both edges of the actually used 20MHz channel bandwidth.
  • the created gaps leave more margin for the UE to perform UL transmission with higher power (i.e., the MPR is tightened/decreased compared to nominal standardized values) , while applying the out-of-band emission requirements and the spurious emission requirements with a 10MHz shift and with the out-of-band emission requirements scaling according to a 20MHz channel bandwidth reference.
  • the virtual bandwidth As with the virtual bandwidth, other gap sizes for the shift are possible, and may not be symmetrical on both sides of the UE channel bandwidth.
  • the frequency-shifted relaxation scheme may also be applied in the out-of-band blocking and/or ACS requirements to create a similar gap at both sides of the actually used 20MHz channel bandwidth, such that the UE may perform DL reception with more required utilized spectrum (e.g., OFDM subcarriers) within the UE’s operating channel, compared to nominal standardized values.
  • OFDM subcarriers e.g., OFDM subcarriers
  • a one-side relaxed out-of-band/spurious emission requirements may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE.
  • the entire channel bandwidth is not transmitted by the UE, and as defined in 3GPP TS 38.101-1, this is called the “transmission bandwidth configuration” and often called “partial RB allocation” .
  • FIG. 7 illustrates an example scenario 700 of one-side relaxed out-of-band/spurious emission requirements in accordance with an implementation of the present disclosure.
  • Scenario 700 depicts an approximately 10MHz of transmission resources (in red) within a 20MHz channel bandwidth.
  • the left edge of the channel does not need the 10MHz shift described in the second proposed scheme of the present disclosure, because there is already a 10MHz gap between the first transmitted frequency resource and the left edge of the channel.
  • the network may transmit a configuration to the UE to indicate the one-side relaxed out-of-band/spurious emission requirements (i.e., to indicate a channel bandwidth where the UE is only allocated with a partial RB allocation of the channel bandwidth) .
  • the solution of frequency-shifted out-of-band/spurious emission requirements may be applied to create a 10MHz gap at the right edge of the channel.
  • the limitation here is that the one-sided relaxation can only apply when the UE is allocated with a partial RB allocation of transmission bandwidth compared to the configured channel bandwidth.

  • the network may transmit a configuration to the UE to indicate the one-side relaxed out-of-band/spurious emission requirements, where corresponding MPR tightening/decreasing may only apply if the UE is allocated with a partial RB allocation of the channel bandwidth.
  • FIG. 8 illustrates an example scenario 800 of one-side relaxed out-of-band/spurious emission requirements in accordance with another implementation of the present disclosure.
  • Scenario 800 depicts a 30MHz virtual channel bandwidth applied around a 20MHz channel bandwidth, with a 10MHz gap created inside the channel due to the partial RB allocation, and another gap outside of the channel (i.e., the gap at the right edge) enabled via the out-of-band emission requirements relaxation with scaling according to a 30MHz channel bandwidth reference.

  • Scenario 900 depicts the frequency-shifted out-of-band/spurious emission requirements, with a 10MHz gap created at both edges of the actually used 20MHz channel bandwidth.
  • the left gap is located between the channel bandwidth actually used by the UE and the edge of the spectrum block provided by the operator.

Abstract

L'invention concerne diverses solutions visant à assouplir des exigences en matière d'émissions d'émetteur ou en matière de blocage de récepteur. Un appareil peut recevoir une signalisation d'un nœud d'un réseau sans fil. La signalisation peut indiquer un assouplissement des exigences en matière d'émissions d'émetteur ou en matière de blocage de récepteur. Ensuite, l'appareil peut appliquer des exigences assouplies en matière d'émissions d'émetteur pour une transmission de liaison montante (UL) ou des exigences assouplies en matière de blocage de récepteur pour une réception de liaison descendante (DL). De plus, ou éventuellement, les exigences assouplies en matière d'émissions d'émetteur peuvent être associées à des exigences de réduction de puissance maximale (MPR) plus strictes/réduites.
