Precoding and SDMA support
First Claim
1. A method for enhancing performance in a wireless communication environment, comprising:
- receiving one or more signals indicative of a user preference associated with a user device for a transmission mode;
associating the user preference with at least one entry in a first codebook comprising one or more entries corresponding to a plurality of transmission modes for a first base station, wherein the first codebook is changed for a second codebook comprising one or more entries corresponding to a plurality of transmission modes for a second base station at least in part in response to the user device transitioning from communicating with the first base station to communicating with the second base station, wherein the first codebook comprises one or more entries that differ from one or more corresponding entries of the second codebook; and
assigning the user device to the transmission mode corresponding to the at least one entry in the first codebook.

Abstract
Embodiments are described in connection with enhancing performance in a wireless communication system using codebook technology. According to an embodiment is a method for enhancing performance in a wireless communication environment. The method can include receiving a user preference for a transmission mode, associating the user preference with an entry or entries in a codebook, and assigning the user to a transmission mode corresponding to the entry or entries. The transmission mode can be one of a precoding, space division multiple access (SDMA), SDMA precoding, multiple input multiple output (MIMO), MIMO precoding, MIMO-SDMA and a diversity. Each entry can correspond to a transmission mode.

7. A method of determining a user'"'"'s preference of a transmission mode at a wireless communication device in communication with a user, comprising:
-
receiving the user preference of the transmission mode and associating the user preference with at least one entry in a first codebook comprising one or more entries corresponding to a plurality of transmission modes for a first base station; determining one or more channel characteristics of the user wireless communication device; selecting the transmission mode from the first codebook, wherein the first codebook is changed for a second codebook comprising one or more entries corresponding to a plurality of transmission modes for a second base station at least in part in response to the wireless communication device transitioning from communicating with the first base station to communicating with the second base station, wherein the first codebook comprises one or more entries that differ from one or more corresponding entries of the second codebook; and transmitting an identifier of the selected transmission mode from the wireless communication device to the first base station. - View Dependent Claims (8, 9, 10, 11, 12)
