APPARATUS AND METHOD FOR COMMUNICATING AND PROCESSING A REFERENCE SIGNAL BASED ON AN IDENTIFIER ASSOCIATED WITH A BASE STATION
First Claim
1. A method for a wireless communication device to process a subframe of orthogonal frequency division multiplexed (OFDM) symbols transmitted by any one of a plurality of base stations in a wireless communication system, the method comprising:
- receiving at least a section of the subframe, the subframe including a plurality of transmission resources multiplexed onto subcarriers of a plurality of OFDM symbols such that a first set of OFDM symbols includes a reference signal and at least a second set of OFDM symbols includes information other than the reference signal;
determining which OFDM symbols of the subframe constitute the first set of OFDM symbols based on an identifier associated with a base station that transmitted the subframe; and
processing the reference signal from OFDM symbols that are determined to be the first set of OFDM symbols.

Abstract
A wireless communication device receives at least a section of a subframe from a base station in a wireless communication system. The subframe includes transmission resources multiplexed onto subcarriers of orthogonal frequency division multiplexed (OFDM) symbols. A first set of OFDM symbols includes a reference signal and at least a second set of OFDM symbols includes information other than the reference signal (e.g., channel-coded data). The wireless device determines which OFDM symbols of the subframe constitute the first set of OFDM symbols based on an identifier associated with a base station that transmitted the subframe. The wireless device may then process the reference signal from the OFDM symbols that are determined to be the first set of OFDM symbols. The wireless device may also determine which OFDM symbols of the subframe constitute the second set of OFDM symbols and process non-reference signal information from OFDM symbols of the second set.

14. A method for a wireless communication device to process a subframe of orthogonal frequency division multiplexed (OFDM) symbols transmitted by any one of a plurality of base stations in a wireless communication system, the method comprising:
-
receiving at least a section of the subframe, the subframe including a plurality of transmission resources multiplexed onto subcarriers of a plurality of OFDM symbols, each transmission resource of the plurality of transmission resources occupying a predetermined amount of time on a respective one of the subcarriers, the plurality of transmission resources being arranged into at least a first set of transmission resources that includes a reference signal and a second set of transmission resources that includes channel-coded data, the first set of transmission resources having been multiplexed into a first set of OFDM symbols and the second set of transmission resources having been multiplexed into a second set of OFDM symbols, the first set of OFDM symbols being different from the second set of OFDM symbols; and determining which OFDM symbols of the subframe constitute the first set of OFDM symbols based on an identifier associated with a base station that transmitted the subframe. - View Dependent Claims (15, 16, 17)
