Licensing Framework for the Auction for Spectrum Licences for Advanced Wireless Services and other Spectrum in the 2 GHz Range

2. Technical Considerations

Details on the band plan and tiers can be found in the AWS Policy Framework, under the headings 'Frequency Blocks' and 'Geographic Tiers'. In summary, the Department will use the same basic block structure as used in the U.S. and described in Figure 1. Figure 1 also shows spectrum blocks B, C and D for the set-aside. The Department is adopting the use of Tier 2 and 3 service areas as described in Figure 2.

2.1 AWS: 1710-1755 MHz/2110-2155 MHz

2.1.1 TDD Operation in the AWS Bands

The Department will allow time division duplexing (TDD) operation in the band if proposed by operators; however, these systems will have to conform to the technical rules established for frequency division duplexing (FDD) operation — i.e. low-power transmissions in the lower sub-band, high-power transmissions in the upper sub-band, out-of-band emission limits, and power flux density limits for coordination purposes. Technical standards are currently being developed in consultation with the Radio Advisory Board of Canada (RABC) and will be published in Standard Radio System Plan 513.

2.1.2 Technical considerations in the AWS Bands

The Department is currently drafting technical standards (Standard Radio System Plan 513 and Radio Standards Specification 139 (RSS-139)) for the AWS band in consultation with the RABC. The SRSP will specify permissible e.i.r.p. (effective isotropic radiated power) limits for mobiles and base stations and the envelope of technical rules for TDD operation. With regard to domestic and international co-channel/adjacent area coordination, the Department will use the same process as it currently uses for the coordination of cellular and PCS systems. This process requires that licensees initiate and coordinate the deployment of systems. In the case of interference resulting from the operation of two AWS systems, licensees are expected to cooperate fully to resolve those conflicts through mutual arrangements. Coordination rules in place for cellular and PCS systems are well established and have been developed in consultation with the industry over the years. Adopting the same rules for the AWS bands received widespread support from respondents to the Consultation.

The Department also notes that as there are a number of systems that operate adjacent channels to the AWS bands, coordination may have to be carried out with these systems. Coordination requirements will be specified in the SRSP.

Radio Standards Specification 113 will provide standards for the certification of transmitters and receivers, including out-of-band emission limits.

2.2 PCS Extension Bands: 1910-1915 MHz/1990-1995 MHz

2.2.1 Technical Standards for the PCS Extension Band

The technical standards for the PCS band (SRSP-510) are currently being updated in consultation with the RABC to include PCS Extension bands 1910-1915 MHz and 1990-1995 MHz. SRSP-510 will provide information on permissible e.i.r.p. limits for mobiles and base stations. Also, as there are a number of systems that operate adjacent-channel to PCS bands, coordination may have to be carried out with these systems. Coordination requirements will be specified in the SRSP. Finally, the SRSP will specify requirements for the domestic and international coordination of cellular and PCS systems that use the same channels in adjacent areas. This process requires that licensees initiate and coordinate the deployment of systems. In the case of interference resulting from the operation of two PCS systems, licensees are expected to cooperate fully to resolve those conflicts through mutual arrangements.

RSS-133 provides standards for the certification of transmitters and receivers, including out-of-band emission limits.

2.3 The Band 1670-1675 MHz

2.3.1 TDD Operation in the Band 1670-1675 MHz

The Department will allow operators to choose whether to deploy FDD or TDD systems in the band. If operators decide to deploy FDD operations, they may use this 5 MHz block paired with another block acquired via auction, and use it for either base or mobile transmissions.

2.3.2 Technical Standards in the Band 1670-1675 MHz

The technical standards for the band 1670-1675 MHz (SRSP-514 and RSS-112) are currently being drafted by the Department in consultation with the RABC. SRSP-514 will provide information on permissible e.i.r.p. limits for mobiles and base stations, as well as coordination requirements for systems in adjacent blocks. Also, the standards will specify the requirements for domestic and international coordination between systems that operate co-channel in adjacent areas.

RSS-112 will provide standards for the certification of transmitters and receivers, including out-of-band emission limits.


Description of Figure 1

This chart shows the general band plan for the AWS commercial mobile spectrum to be auctioned. Six blocks (namely, blocks A, B, C, D, E and F) in the frequency range between 1710-1755 MHz, paired with the same blocks in the frequency range between 2120-2155 MHz.
