Transmission and detection of overhead channels and signals in a wireless network

摘要

Techniques for transmitting and detecting for overhead channels and signals in a wireless network are described. In an aspect, a base station may blank (i.e., not transmit) at least one overhead transmission on certain resources in order to detect for the at least one overhead transmission of another base station. In one design, the base station may (i) send the overhead transmission(s) on a first subset of designated resources and (ii) blank the overhead transmission(s) on a second subset of the designated resources. The designated resources may be resources on which the overhead transmission(s) are sent by macro base stations. The base station may detect for the overhead transmission(s) from at least one other base station on the second subset of the designated resources. In another aspect, the base station may transmit the overhead transmission(s) on additional resources different from the designated resources.

1. A method for wireless communication, comprising:
sending, by a base station, at least one overhead transmission on a first subset of designated resources, wherein the designated resources are designated for overhead transmissions to be sent by macro base stations on the same designated resources, such that two or more of the macro base stations both transmit on the first subset of the designated resources; blanking, by the base station, the at least one overhead transmission on a second subset of the designated resources, wherein the second subset of the designated resources is selected pseudo-randomly by the base station; and detecting, by the base station, an overhead transmission from at least one other base station on the second subset of the designated resources.
