Resource specification for broadcast/multicast services

摘要

Techniques for supporting multimedia broadcast/multicast services (MBMS) are described. In an aspect, resources used for MBMS services may be provided with a multi-tier structure. In the first tier, resources (e.g., subframes) used for a multicast control channel (MCCH) for MBMS services may be signaled in a system information block (SIB). In the second tier, resources (e.g., subframes) for channels carrying data for MBMS services may be signaled via the MCCH. In one design, a base station/cell may determine resources used to send a MCCH. The cell may generate a SIB comprising information indicative of the resources used to send the MCCH. The cell may send the SIB in a broadcast control channel (BCCH). The cell may send the MCCH on the resources indicated by the information sent in the SIB. The cell may send other channels carrying data for MBMS services based on information sent in the MCCH.

1. A method of supporting multimedia broadcast/multicast services (MBMS), comprising:
determining resources used to send a multicast control channel (MCCH); generating a system information block (SIB) comprising information indicative of the resources used to send the MCCH; sending the SIB in a broadcast control channel (BCCH), wherein the SIB is a system information block type x (SIBx), where x is a value greater than 2; determining at least one multicast channel (MCH) subframe allocation pattern (MSAP) for at least one MCH carrying data for MBMS services, each MSAP indicating subframes used for a corresponding MCH, wherein the subframes indicated by each MSAP comprise a subset of subframes available to send the MBMS services; and sending the at least one MSAP in the MCCH.
