摘要： Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

摘要： Techniques are provided for single carrier optimization. For example, there is provided a method that involves, in a subframe of a radio spectrum, allocating a first set of resource elements (REs) for multimedia broadcast over a single frequency network (MBSFN) transmissions, each symbol corresponding to each RE of the first set having a first cyclic prefix (CP) type. The method may involve allocating a second set of REs for unicast transmissions, each symbol corresponding to each RE of second set having a second CP type. The method may involve determining whether the first CP type and the second CP type are the same. The method may involve, in response to the first CP type and the second CP type being the same, combining the MBSFN transmissions and the unicast transmissions in the subframe according to the allocated first and second sets of REs.

摘要： Transmission of eMBMS signals by at least one network entity of a wireless communications system may include coordinating transmission of eMBMS signaling with a remote access point of a wireless communications system to broadcast the eMBMS signaling from a multiple antenna matrix comprising at least one antenna of the network entity and at least one antenna of the access node. The network entity may be an access point. The access point may vary a precoding matrix applied to the eMBMS signaling to transmit from the network entity, or use alternative techniques for providing transmit diversity. Accordingly, the access point may provide transmit diversity for the eMBMS signaling transmitted from the multiple antenna matrix implemented between different cells on the wireless communication network. The access point may vary the precoding matrix to cause cyclical rotation of beam direction for the eMBMS transmissions from different cells of the network.

摘要： Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.
