    摘要: Techniques for transmitting data using a combination of explicit cyclic delay and implicit cyclic delay are described. A transmitter may perform first processing for cyclic delay diversity (or explicit cyclic delay processing) based on a first set of cyclic delay values known to a receiver. The transmitter may perform precoding based on a precoding matrix either before or after the explicit cyclic delay processing. The transmitter may perform second processing for cyclic delay diversity (or implicit cyclic delay processing) based on a second set of cyclic delay values unknown to the receiver. The transmitter may perform both explicit and implicit cyclic delay processing for data and may perform only implicit cyclic delay processing for pilot. One entity may select the first set of cyclic delay values and inform the other entity. The transmitter may autonomously select the second set of cyclic delay values without informing the receiver.

    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: In a wireless communication system unused resource elements are utilized to transmit additional pilot and control signals. The additional pilot and control signals may mitigate the impact of interference. The unused resource elements may be in a downlink pilot timeslot (DwPTS) in a time division duplex system.

    摘要: Different sequence resources can be allocated to a mobile device where the mobile device can exclusively uses the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place—moreover, a cyclic shift result can be employed in sequence resource allocation to attempt to minimize interference.
