Section: 6.2.5D Configured transmitted power for ProSe
Content: 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 PCMAX,c and power boundary requirement specified in subclause 6.2.5 shall apply to UE supporting ProSe, where - MPRc is specified in subclause 6.2.3D; - A-MPRc is specified in subclause 6.2.4D; - TProSe = 0.1 dB. For and, PEMAX,c is the value given by IE P-Max for serving cell c, defined by [7], when present. PEMAX,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, PEMAX,c is the value given by the IE discMaxTxPower in [7]. For, PEMAX,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 PEMAX,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 PCMAX,c,E-UTRA and PCMAX,c,ProSe for the configured E-UTRA uplink carrier and the configured E-UTRA ProSe carrier, respectively, and its total configured maximum output power PCMAX,c. The configured maximum output power PCMAX c,E-UTRA(p) in subframe p for the configured E-UTRA uplink carrier shall be set within the bounds: PCMAX_L,c,E-UTRA (p) ≤ PCMAX,c,E-UTRA (p) ≤ PCMAX_H,c,E-UTRA (p) where PCMAX_L,c,E-UTRA and PCMAX_H,c,E-UTRA are the limits for a serving cell c as specified in subclause 6.2.5. The configured maximum output power PCMAX c,ProSe (q) in subframe q for the configured E-UTRA ProSe carrier shall be set within the bounds: PCMAX,c,ProSe (q) ≤ PCMAX_H,c,ProSe (q) where PCMAX_H,c,ProSe is the limit as specified in subclause 6.2.5D. The total UE configured maximum output power PCMAX (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: PCMAX_L (p,q) ≤ PCMAX (p,q) ≤ PCMAX_H (p,q) with PCMAX_L (p,q) = PCMAX_L,c,E-UTRA (p) PCMAX_H (p,q) = MIN {10 log10 [pCMAX_H,c,E-UTRA (p) + pCMAX_H,c,ProSe (q)], PPowerClass} where pCMAX_H,c,ProSe and pCMAX_H,c,E-UTRA are the limits PCMAX_H,c,ProSe (q) and PCMAX_H,c,E-UTRA (p) expressed in linear scale. The measured total maximum output power PUMAX over both the E-UTRA uplink and E-UTRA ProSe carriers is PUMAX = 10 log10 [pUMAX,c,E-UTRA + pUMAX,c,ProSe], where pUMAX,c,E-UTRA denotes the measured output power of serving cell c for the configured E-UTRA uplink carrier, and pUMAX,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, PCMAX_L(p, q) – TLOW (PCMAX_L(p, q)) ≤ PUMAX ≤ PCMAX_H(p, q) + THIGH (PCMAX_H(p, q)) where PCMAX_L (p,q) and PCMAX_H (p,q) are the limits for the pair (p,q) and with the tolerances TLOW(PCMAX) and THIGH(PCMAX) for applicable values of PCMAX specified in Table 6.2.5C-1. PCMAX_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 PCMAX 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 PCMAX tolerance For the reference subframe p duration when uplink carrier leads: P'CMAX_L = PCMAX_L,,cE-UTRA (p) P'CMAX_H = MAX {PCMAX_H (p,q-1) , PCMAX_H (p,q)} For the reference subframe p duration when ProSe carrier leads: P'CMAX_L = PCMAX_L,cE-UTRA (p) P'CMAX_H = MAX {PCMAX_H (p,q) , PCMAX_H (p,q+1)} where PCMAX_L,,cE-UTRA (p) and PCMAX_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 PUMAX shall be within the following bounds: P’CMAX_L – TLOW (P’CMAX_L) ≤ PUMAX ≤ P’CMAX_H + THIGH (P’CMAX_H) with the tolerances TLOW(PCMAX) and THIGH(PCMAX) for applicable values of PCMAX specified in Table 6.2.5C-1.
