Abstract: A cooperative sensing technique (300) operates by selecting a group of subscribers (302) from a secondary system, measuring a cooperative sensing metric (306) and then using the metric to identify an achievable spatial diversity gain for the group of selected subscribers (308). Once an achievable spatial diversity gain is determined for the group (308/412), it is compared to a required spatial diversity gain (310), and if the condition is met at (310), the validated group can begin spectrum sensing (314) to identify a vacant/suitable channel for operation. If the achievable spatial diversity gain is insufficient, then a new group of users is selected (312) within the secondary system and the process repeats itself.

A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator.

The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.

Abstract: In a wireless communication system a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that &; of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes˜results in failure of data recovery.
