Definitions

  • the invention generally relates to wireless communication systems.
  • the invention relates to point to multi-point services in such systems.
  • point to multi-point services there is a growing desire to use point to multi-point services in wireless communication systems. As shown in FIG. 1 in point to multi-point, one service is sent from a single point, such as a base station, to multiple points, such as user equipments. Examples of point to multi-point services are multimedia broadcasts and multicast services.
  • FACH forward access channel
  • TrCH downlink common transport channel
  • S-CCPCH secondary common control physical channel
  • the S-CCPCH data rate is limited.
  • a high data rate service was transmitted over the S-CCPCH, it would need to be transmitted using a low data redundancy to achieve that high data rate.
  • the S-CCPCH is transmitted to the entire cell, it is transmitted at a power level sufficient for reception by a user at the periphery of the cell at a desired quality of service (QOS). Broadcasting a high data rate service at this power level would increase interference to other users reducing the capacity of system, which is extremely undesirable.
  • QOS quality of service
  • the modulation and coding set (MCS) and transmission power level used by the S-CCPCH needs to be sufficient to maintain a desired QOS at the periphery of the cell.
  • a shared channel proposed for use in the 3GPP system is the high speed downlink shared channel (HS-DSCH).
  • the HS-DSCHs are high speed channels which are time shared by the cell users (user equipments). Each transmission is targeted to a separate user and each user's transmission over the HS-DSCH is separated by time.
  • the HS-DSCH transmissions to a user are associated with an uplink and a downlink dedicated control channels. Each user sends measurements via layer 1 and layer 3 signaling in the uplink control channel. Using these measurements, a modulation and coding set (MCS) is selected for that user's transmissions.
  • MCS modulation and coding set
  • the MCS can be changed every 2 to 10 milliseconds.
  • the HS-DSCH allows for a more efficient utilization of radio resources, only point to point services can be handled by the HS-DSCH. To handle multiple reception points, multiple transmissions must be made over the HS-DSCH. Such multiple transmissions utilize a large amount of radio resources, which is undesirable.
  • Service data is transferred in a wireless communication system.
  • a first service identification is transmitted for reception by a group of users of a cell in the system.
  • the group of users does not include all of the users of the cell.
  • Each of the group of users receives the service identification.
  • Each of the group of users monitors for a second service identification being transmitted over a high speed downlink shared channel (HS-DSCH).
  • the service data is transmitted over the HS-DSCH with the second service identification.
  • Each of the group of users detects the second service identification and receives the service data of the HS-DSCH.
  • FIG. 1 is an illustration of a point to multi-point service.
  • FIG. 2 are illustrations of a preferred HS-DSCH and associated control channels.
  • FIG. 3 is simplified diagram of a preferred Node-B and user equipment.
  • FIG. 4 is a simplified diagram of a preferred Node-B with a scheduling mechanism for the preferred HS-DSCH.
  • FIGS. 5A and 5B are illustrations of preferred HS-DSCH signaling for the HSDSCH.
  • FIG. 6 is an illustration of preferred signals for establishment and transmission of a point to multi-point service over a HS-DSCH.
  • FIG. 7 is an illustration of channel mapping performed by the radio network controller and the user equipment for a point to multi-point service over a HS-DSCH.
  • FIG. 2 is an illustration of a preferred HS-DSCH 16 and its associated downlink control channel(s) 13 for use in transmitting a point to multi-point (PtM service.
  • a group of users UE 1 12 1 , . . . , UE J 12 J , . . . , UE N 12 N , are to receive the service over the HS-DSCH 16 .
  • a downlink common control channel (CCC) 13 is utilized to allocate the HS-DSCH 16 for the users, UE 1 12 1 , . . . , UE J 12 J , . . . , UE N 12 N .
  • CCC downlink common control channel
  • the HS-DSCH 16 is sent by a base station 10 and is received by the group of UEs 12 1 - 12 N .
  • UEs such as UE X 12 X , not registered for the service do not match the service identifier on the CCC 13 . Therefore, this UE, UE X 12 X , is not configured to receive data of the HS-DSCH 16 .
  • FIG. 3 is a simplified diagram of a Node-B 18 and one of the UEs, UE J 12 J , for use in transferring data over the HS-DSCH 16 .
  • a downlink control channel generator 24 produces the CCC signal for each UE 12 1 - 12 N .
  • the CCC 13 is radiated by an antenna 32 or antenna array through the wireless radio interface 22 , it is received by an antenna 34 or an antenna array of the UE J 12 J and processed by a CCC receiver 36 to recover control information of the channel, such as a modulation and coding set of the HS-DSCH 16 .
  • a HS-DSCH generator 26 produces the HS-DSCH signal for transfer through the wireless interface 22 .
  • the HS-DSCH signal is received by the UE J 12 J using its antenna 34 or antenna array.
  • Information of the HS-DSCH 16 is recovered using the CCC information by a HS-DSCH receiver 38 .
  • a channel quality measuring device 40 takes channel quality measurements/information of the HS-DSCH, such as the signal to interference ratio (SIR) or block error rate (BLER). Channel quality can also be derived from the downlink associated dedicated channel.
  • the measurements/information is sent to the Node-B 18 , by an uplink physical control channel (UCC) transmitter, or by layer 3 signaling procedures.
  • UCC uplink physical control channel
  • an automatic repeat request (ARQ) transmitter 41 at the user equipment 12 transmits acknowledgments (ACKs) and negative ACKs (NAKs) indicating whether the HS-DSCH information was received successfully.
  • the Node-B 18 checks the ACKs/NAKs for all users. Typically, if any user sends a NAK, a retransmission is made. However, a retransmission may only be triggered if only a number of NAKs exceeding a threshold is met. Typically, time limits are set for retransmissions. Preferably, the UEs 12 ACKing ignore subsequent retransmissions saving their power.
  • a channel quality measurement processor 30 recovers the channel quality measurements/information from all the users of the HS-DSCH.
  • a modulation and coding set (MCS) selection device 28 uses the channel measurements/information from each of the users registered to receive the PtM service (user group) to select a MCS for the HS-DSCH transmission.
  • the selected MCS is the least robust (highest data rate) that the channel conditions permit for the user within this PtM user group having the poorest received measured HS-DSCH signal quality.
  • the MCS is updated every transmission time interval (TTI), although a longer time period can be used.
  • the CCC generator 24 produces the CCC indicating the selected MCS to UE 1 12 1 , . . . , UE J 12 J , . . . , UE N 12 N for proper reception of the HS-DSCH.
  • the HS-DSCH generator 26 produces the HS-DSCH 16 using the selected MCS.
  • the transmission characteristics of the various sub-streams may be handled separately.
  • a multimedia service may have an audio, video and text sub-streams.
  • the QOS of each sub-stream may differ allowing different transmission attributes to be used by each sub-stream. This approach allows for better resource efficiency. Instead of transmitting each sub-stream to meet the highest QOS sub-stream requirements, they can be handled separately.
  • the block error rate (BLER) is compared to a BLER quality target for each sub-stream.
  • FIG. 4 is a simplified block diagram of a preferred scheduling mechanism for the Node-B 18 .
  • the scheduling mechanism 46 is preferably used to schedule data every TTI, although a longer scheduling period may be used.
  • the scheduling mechanism 46 receives point to point (PtP) and PtM data to be transmitted over the HS-DSCH.
  • the scheduler is determining which users will receive PtP transmissions and which user groups will receive PtM transmissions in the next TTI.
  • Scheduling the transfer of data over the preferred time period allows for a more efficient utilization of radio resources.
  • the scheduling mechanism 46 may increase the amount of PtM data transmitted through the HS-DSCH channel due to the increased availability of the radio resources in that TTI.
  • the scheduler 46 may choose to transmit PtP services when PtM data is not available.
  • Another scheduling criteria is QoS attributes, such as transmission latency and/or data throughput requirements of the PtP or PtM service. Scheduling on a TTI basis offers a greater ability to achieve these requirements while maintaining high utilization of HS-DSCH cell resources.
  • the scheduler 46 may also take into account physical transmission requirements. For example, one user or user group may require a more robust MCS than another. During the next TTI resources may only be available for a less robust MCS. The scheduler 46 may then schedule transmissions for PtP users or PtM user groups that maximize the use of available resources. Since data available for transmission with specific QOS requirements, available physical resources and channel quality measurements change on a TTI basis, the ability to schedule within this interval improves the number of satisfied users and the overall utilization and efficient use of physical resources.
  • the scheduler 46 also gets ACK/NAK feedback from all users in the PtM user group and schedules retransmissions until all users indicate successful reception of the transmission by sending a ACK, or a certain configured threshold is reached, or a service transmission time limit is reached or a retransmission limit is reached.
  • the advantage of this approach is that only segments of a PtM service that are in error are retransmitted, rather than retransmitting the entire service transmission. Preferably, users that have previously generated an ACK will ignore any retransmissions.
  • a benefit of this approach is the ability to dynamically schedule on a TTI basis between PtP and PtM services rather than scheduling S-CCPCH with layer 3 procedures that require the order of 100 s of ms to seconds for channel allocations.
  • This offers improved QOS and physical resource management. Additionally, it allows the UE to receive multiple services without the capability for reception of simultaneous channels, since overlapping physical allocations can be avoided. The multiple services are separated by time.
  • the Node-B 18 signals on the CCC 13 to the UEs 12 1 - 12 N the channel configuration that data for UE 12 1 - 12 N will be sent.
  • the preferred scheduling for each TTI reduces resource conflicts between services, by maximizing use of radio resources.
  • This assignment of channels is signaled to the users via the downlink CCC using a signaling device 48 . Without the mechanism 46 , the channels typically can not be reallocated on a TTI granularity and as a consequence the ability to maintain QOS with high utilization and efficient use of physical resources is restricted.
  • FIGS. 5A and 5B are illustrations of preferred HS-DSCH signaling for the HS-DSCH 16 .
  • each UE 12 1 - 12 N of the PtM user group is notified of the service transmission by detecting a PtM service ID 51 associated with all users of the service. That service ID 51 is encoded on the downlink common control channel 13 . After a predetermined time period, the users receive the HS-DSCH of the authorized service.
  • each UE 12 1 - 12 N is notified of the service transmission by detecting an ID associated with its group of UEs, UE group ID 1 53 1 to UE group ID N 53 N , encoded on the downlink common control channel 13 .
  • the users receive the HS-DSCH 16 indicated by the CCC 13 for a packet having a service ID of the authorized service.
  • FIG. 6 is an illustration of preferred signals for establishment and transmissions of a point to multi-point service over HS-DSCHs.
  • the RAN 70 signals to each user to receive the service the transport attributes of the transmission, 74 .
  • Each user configures itself for reception of the transmission and monitors the CCCs for the PtM service group ID, 72 .
  • Data to be sent for the point to multi-point service is received from the core network by the UMTS radio access network (UTRAN) 70 .
  • the service/group/UE ID on the CCC indicates that the HS-DSCH transmission will occur shortly, after a specified time period on a specified HS-DSCH physical channel.
  • UTRAN UMTS radio access network
  • Each user may send channel quality information to the RAN 70 with layer 3 signaling procedures, 76 .
  • the sending of the channel information is also reported on a TTI basis by physical layer signaling, 78 .
  • the RAN 70 uses the channel quality information for all the users within each PtM user group to determine appropriate MCS of HS-DSCH transmissions to each PtM user group.
  • the RAN 70 would typically set the MCS at a level for reception at a desired QOS by the user having the worst reception quality.
  • these parameters are preferably updated every time transmission interval (TTI), although a longer time period between updates may be used.
  • TTI time transmission interval
  • the UTRAN 70 synchronizes the HS-DSCH allocations, 82 , and each UE 12 configures the HS-DSCH reception, 84 .
  • Service data is transmitted on the HS-DSCH, 86 .
  • the service data transmitted on the HS-DSCH is received by the UE 12 .
  • the service data is forwarded to the common traffic channel.
  • the preferred architecture allows for the flexibility for transferring common traffic channel data over shared or dedicated channels as PtM or PtP transmission. This mapping is performed for both on the transmission and reception side of the wireless interface.
  • FIG. 7 is an illustration of the preferred channel mapping at a radio network controller 19 and UE 12 .
  • PtM data arrives at the RNC on a common traffic channel (CTCH).
  • CTCH is mapped onto the HS-DSCH for transfer to the user over the physical channel, HS-PDSCH.
  • a UE 12 as illustrated here and typically multiple UEs receive the HS-DSCH transmission.
  • UE 12 receives the HS-PDSCH and maps the HS-DSCH to the CTCH for processing by the UE 12 .
