36.1013GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TSUser Equipment (UE) radio transmission and reception

When UE is configured for E-UTRA ProSe sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA ProSe operating bands specified in Table 5.5D-1, the configured maximum output power P_CMAX,c and power boundary requirement specified in subclause 6.2.5 shall apply to UE supporting ProSe, where

– MPR_c is specified in subclause 6.2.3D;

– A-MPR_c is specified in subclause 6.2.4D;

– T_ProSe = 0.1 dB.

For and, P_EMAX,c is the value given by IE P-Max for serving cell c, defined by [7], when present. P_EMAX,c is the value given by IE maxTxPower, defined by [7], when the UE is not associated with a serving cell on the ProSe carrier .

For, P_EMAX,c is the value given by the IE discMaxTxPower in [7].

For, P_EMAX,c is the value given by the IE maxTxPower in [7] when the ProSe UE is not associated with a serving cell on the ProSe carrier. When the UE is associated with a serving cell, then P_EMAX,c is the value given by the IE P-Max when PSBCH/SLSS transmissions is triggered for ProSe Direct communication as specified in [7], and is the value given by the IE discMaxTxPower in [7] otherwise.

For, the value is as calculated for and applying the MPR for SSSS as specified in Section 6.2.3D.

When a UE is configured for simultaneous E-UTRA ProSe sidelink and E-UTRA uplink transmissions for inter-band E-UTRA ProSe / E-UTRA bands specified in Table 5.5D-2, the UE is allowed to set its configured maximum output power P_{CMAX,c,E-UTRA} and P_CMAX,c,ProSe for the configured E-UTRA uplink carrier and the configured E-UTRA ProSe carrier, respectively, and its total configured maximum output power P_CMAX,c.

The configured maximum output power P_{CMAX c,E-UTRA}(p) in subframe p for the configured E-UTRA uplink carrier shall be set within the bounds:

P_{CMAX_L,c,E-UTRA} (p) ≤ P_{CMAX,c,E-UTRA} (p) ≤ P_{CMAX_H,c,E-UTRA} (p)

where P_{CMAX_L,c,E-UTRA} and P_{CMAX_H,c,E-UTRA} are the limits for a serving cell c as specified in subclause 6.2.5.

The configured maximum output power P_{CMAX c,ProSe} (q) in subframe q for the configured E-UTRA ProSe carrier shall be set within the bounds:

P_CMAX,c,ProSe (q) ≤ P_{CMAX_H,c,ProSe} (q)

where P_{CMAX_H,c,ProSe} is the limit as specified in subclause 6.2.5D.

The total UE configured maximum output power P_CMAX (p,q) in a subframe p of an E-UTRA uplink carrier and a subframe q of an E-UTRA ProSe sidelink that overlap in time shall be set within the following bounds for synchronous and asynchronous operation unless stated otherwise:

P_{CMAX_L} (p,q) ≤ P_CMAX (p,q) ≤ P_{CMAX_H} (p,q)

with

P_{CMAX_L} (p,q) = P_{CMAX_L,c,E-UTRA} (p)

P_{CMAX_H} (p,q) = MIN {10 log₁₀ [p_{CMAX_H,c,E-UTRA} (p) + p_{CMAX_H,c,ProSe} (q)], P_PowerClass}

where p_{CMAX_H,c,ProSe} and p_{CMAX_H,c,E-UTRA} are the limits P_{CMAX_H,c,ProSe} (q) and P_{CMAX_H,c,E-UTRA} (p) expressed in linear scale.

The measured total maximum output power P_UMAX over both the E-UTRA uplink and E-UTRA ProSe carriers is

P_UMAX = 10 log₁₀ [p_{UMAX,c,E-UTRA} + p_UMAX,c,ProSe],

where p_{UMAX,c,E-UTRA} denotes the measured output power of serving cell c for the configured E-UTRA uplink carrier, and p_UMAX,c,ProSe denotes the measured output power for the configured E-UTRA ProSe carrier expressed in linear scale.

When a UE is configured for synchronous ProSe and uplink transmissions,

P_{CMAX_L}(p, q) – T_LOW (P_{CMAX_L}(p, q)) ≤ P_UMAX ≤ P_{CMAX_H}(p, q) + T_HIGH (P_{CMAX_H}(p, q))

where P_{CMAX_L} (p,q) and P_{CMAX_H} (p,q) are the limits for the pair (p,q) and with the tolerances T_LOW(P_CMAX) and T_HIGH(P_CMAX) for applicable values of P_CMAX specified in Table 6.2.5C-1. P_{CMAX_L} may be modified for any overlapping portion of subframes (p, q) and (p +1, q+1).

When a UE is configured for asynchronous ProSe and uplink transmissions, the carrier configured for uplink transmission is taken as the reference. If subframe p for the E-UTRA uplink carrier and subframe q for the E-UTRA ProSe carrier overlap in time and

1. if uplink carrier leads in time over q, then p is the reference subframe and, the (p,q) and (p,q-1) pairs are considered for determining the P_CMAX tolerance

2. if ProSe carrier leads in time over p, then p is the reference subframe and, the (p,q) and (p,q+1) pairs are considered for determining the P_CMAX tolerance

For the reference subframe p duration when uplink carrier leads:

P’_{CMAX_L} = P_{CMAX_L,,cE-UTRA} (p)

P’_{CMAX_H} = MAX {P_{CMAX_H} (p,q-1) , P_{CMAX_H} (p,q)}

For the reference subframe p duration when ProSe carrier leads:

P’_{CMAX_L} = P_{CMAX_L,cE-UTRA} (p)

P’_{CMAX_H} = MAX {P_{CMAX_H} (p,q) , P_{CMAX_H} (p,q+1)}

where P_{CMAX_L,,cE-UTRA} (p) and P_{CMAX_H} are the applicable limits for each overlapping subframe pairs (p,q) , (p, q+1) , (p, q-1). The measured total configured maximum output power P_UMAX shall be within the following bounds:

P’_{CMAX_L} – T_LOW (P’_{CMAX_L}) ≤ P_UMAX ≤ P’_{CMAX_H} + T_HIGH (P’_{CMAX_H})

with the tolerances T_LOW(P_CMAX) and T_HIGH(P_CMAX) for applicable values of P_CMAX specified in Table 6.2.5C-1.
