Each of the foregoing applications are incorporated by reference as if fully set forth.
For the UL E-UTRA, there are several intra-cell PC proposals, which have been submitted to third generation partnership project (3GPP) long term evolution (LTE) work group (WG) #1. These proposals can be generally divided into slow open loop PC and slow closed loop, (or CQI based PC). Open loop PC can compensate for long-term channel variations, (e.g., pathloss and shadowing), in an effective way, for instance, without the history of the transmit power, but it typically suffers from errors in pathloss measurement and transmit power setting. On the other hand, slow closed loop or CQI based PC is less sensitive to errors in measurement and transmit power setting, because it is based on feedback signaled from the eNodeB. However, it degrades performance when there is no available feedback due to UL transmission pause or pauses in the feedback transmission.
PSD Tx ⁡ ( n ) = ⁢ PSD open ⁡ ( n ) + α · Δ closed ⁡ ( n ) + Δ MCS ⁡ ( n ) = ⁢ PSD TX ′ ⁡ ( n - 1 ) + ⁢ ( PSD open ⁡ ( n ) - PSD open ⁡ ( n - 1 ) ) + ⁢ α · ( Δ closed ⁡ ( n ) - Δ closed ⁡ ( n - 1 ) ) + ⁢ Δ MCS ⁡ ( n ) ; Equation ⁢ ⁢ ( 2 )
PSDopen=PSDtarget+L(dBm); Equation (3)
Lk=ρ·Lk−1+(1−ρ)·Lk; Equation (4)
where Lk−1 and Lk represent the filtered pathloss at the (k−1)-th instance and instantaneous pathloss at the k-th instance; ρ is a filter coefficient, 0≤ρ≤1, which is generally determined by WTRU 20, depending on pathloss variation, fast fading rate, the time of UL transmission, and others, for example. The filtering for pathloss can be done in PHY layer and/or L 2/3 layer.
Δclosed=f(PC correctioncommand(s)); Equation (5)
f(UL grant assignment SINTT)=SINRT−E{SINRest(UL grant assignment)}; Equation (10)
Similar to Equation (1), the correction factor in Equation (8) may be used to compensate for open loop errors. The main advantage to using Equation (8) is that it does not require explicit correction command signaling in the UL grant in the DL L1/L2 control channel (resulting in reduced signaling overhead), while Equation (1) (and Equation (2)) needs the explicit command to be signaled in the UL grant (and/or the DL scheduling). Using Equation (3), the closed loop component may be based on the UL grant assignment (e.g., MCS and/or TB S), without the explicit correction command signaling in the UL grant in the DL L1/L2 control channel.
PSD Tx = P 0 + SINR Target + α · PL ︸ PSD open + β · Δ closed + Δ MCS ⁢ ⁢ ( dBm ) ; Equation ⁢ ⁢ ( 12 )
PSD Tx ⁡ ( n ) = ⁢ PSD open ⁡ ( n ) + α · Δ closed ⁡ ( n ) + Δ MCS ⁡ ( n ) = ⁢ PSD TX ′ ⁡ ( n - 1 ) + ⁢ ( PSD open ⁡ ( n ) - PSD open ⁡ ( n - 1 ) ) + ⁢ α · ( Δ closed ⁡ ( n ) - Δ closed ⁡ ( n - 1 ) ) + ⁢ Δ MCS ⁡ ( n ) ; Equation ⁢ ⁢ ( 13 )
PTx=min{Pmax,(10·log10(M)+PSDTx)} (dBm); Equation (14)
PLk=ρ·PLk−1+(1−ρ)·PLk Equation (17)
where PLk and PLk−1 represent the filtered pathloss at the k-th instance and (k−1)-th instant, respectively. Lk is the instantaneous pathloss at the k-th instant. ρ is a filter coefficient, 0≤ρ≤1, which is generally determined by WTRU 20, depending on pathloss variation, fast fading rate, the time of UL transmission, etc. Alternatively, a moving averaging method may be considered for the pathloss filtering.
Δclosed=└ESINRest−SINRtarget┘ Equation (18)
PSDTX(n)=PSD′Tx(n−1)+(PSDopen(n)−PSDopen(n−1))+ΔMCS(n); Equation (19)
Δ ⁡ ( IoT S ) = { δ < 0 , when ⁢ ⁢ IoT S = 1 ⁢ ⁢ or ⁢ ⁢ “ down ⁢ ⁢ command ” 0 , when ⁢ ⁢ IoT S = 0 , “ DTX , ” ⁢ ⁢ or ⁢ ⁢ “ up ⁢ ⁢ command ”
δ = { δ , for ⁢ ⁢ WTRUs ⁢ ⁢ at ⁢ ⁢ cell ⁢ ⁢ edge δ x , for ⁢ ⁢ cell ⁢ ⁢ interior ⁢ ⁢ WTRUs ⁢ ⁢ where ⁢ ⁢ x > 1
If (pathloss_serving_cell−pathloss_strongest_neighboring_cell)<R (dB), x=4; where R represents the virtual boundary layer between the cell interior zone and cell edge zone. The parameter R may be broadcast by eNodeB 30 semi-statically.
f(CQI,SINTT)=SINRT−E{SINRest(CQI)} (dB); Equation (25)
E{SINRest(CQIk)}=ρ·E{SINRest(CQIk−1)}+(1−ρ)·E{SINRest(CQIk)}; Equation (26)
eNodeB 30 preferably signals parameters, including a target SINR level, SINRT, which is a WTRU (or a sub-group of WTRUs)-specific parameter, where the target SIR may be adjusted through an outer loop mechanism based on QoS like target BLER. The target SINR may be also a function of the pathloss measurement. The signaling of the target SIR is done via in-band L1/2 control signaling upon its adjustment. A power control margin, K, which is an eNodeB-specific parameter is also signaled by eNodeB 30. K is preferably semi-static and signaled via the broadcast channel (BCH). It should be noted that even though K is assumed to be separately signaled along with the other parameters, it may be embedded in the target SINR, i.e., SINRT(after embedding)=SINRT+K (dB). In this case, explicit signaling of K to WTRU 20 is not required.
