    摘要: This invention is a method for extending the coverage and/or improving the capacity of wireless communication networks comprising inserting a Relay Node (RN) in the Radio Access Network (RAN). The relay node relays the signal between the Base Station node (eNB) and the User Equipment (UE). The relay node is wirelessly connected to the base station. The base station uses the same radio access technology (RAT) for the base station to user equipment link and the base station to relay node link. The relay node uses the same radio access technology for the base station to relay node link and the relay node to user equipment link. The relay node is non-transparent and seen as base station by the user equipment.

    摘要: Transmission with multiple antennas in a wireless network is performed by transmitting a plurality of reference sequences (RS) from a UE. A first RS s1[k] is produced using a first cyclic shift and a base sequence s0[k], wherein k={1, 2 . . . K} is an element index. A second RS s2[k] is produced using a second cyclic shift and s0[k]. A first symbol sequence x1[k] is produced using at least s1[k] and s2[k], for at least one k. A second symbol sequence x2[k] is produced using at least s1[k] and s2[k], for at least one k. x1[k] is transmitted using a first transmit antenna and x2[k] is transmitted using a second transmit antenna.

    摘要: A transmission of information within a wireless cellular network may include a first and second type of information. A subframe is produced that includes a plurality of symbols, wherein at least one symbol is designated as a data symbol and at least one symbol is designated as a reference signal symbol that contains a pre-defined reference signal. The first type of information is embedded in the data symbols. If the second type of data is expected, then the second type of information is embedded in at least one reference symbol by quadrature amplitude modulating the pre-defined reference signal. The subframe is then transmitted from one node in the network to a second node. In some embodiments, if it is determined that the second node is not expecting the second type of information, then a discontinuous transmission (DTX) response is embedded in the reference symbol instead of the second type of information.

    摘要: Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. One or more priority symbols are generated using the digital samples of the priority information. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. For example, Rank Indicator (RI) is transmitted using symbol k, ACKNAK is transmitted using symbol k+1; and the reference signal (RS) is transmitted using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time. The other symbols are transmitted in available locations.

    摘要: A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed. Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.

    摘要: This invention is a method for time-sharing sounding resources. A first embodiment defines one common sounding period for all user equipment and all sounding resources. A second embodiment allows for different sounding periods so long as each individual sounding resource uses only one sounding period. A third embodiment offers the most flexibility in sharing of the sounding resources by permitting changes in time. The first option is a special case of the second option. The second option is a special case of the third option.

    摘要: A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). UEs are synchronized to the eNB upon entry to the cell. If a particular UE has data to transmit, it will be placed in a connected state and scheduled for transmission. Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed in response to receiving a scheduled transmission from each respective UE in the scheduled portion; Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.
