TW201735676A - Devices and methods for providing 5G uplink request - Google Patents

Abstract

Devices and methods of scheduling uplink data requests in 5G systems are generally described. A UE transmits a scheduling request (SR) or an 5G physical random access channel (xPRACH) to an eNB on a 5G or LTE link resource reserved for 5G scheduling requests or unreserved. The message is dependent on which of link is used for the transmission. Depending on whether a reserved resource and a reserved logical channel ID is used, the UE transmits the eNB with a BSR and perhaps a beam measurement report after sending an SR and in response to receiving an uplink grant for the same. The UE then transmits a 5G physical uplink shared channel in response to receiving on an optimal beam an 5G physical downlink control channel containing a 5G uplink grant for the data. When an xPRACH is transmitted, a reduced random access response is used.

Description

Apparatus and method for providing 5G uplink request

The embodiment belongs to a radio access network. Some embodiments provide information on cellular and wireless local area network (WLAN) networks, including 3rd Generation Partnership Project Long Term Evolution (3GPP LTE) networks and LTE Upgraded (LTE-A) networks, and fourth Generation (4G) network and fifth generation (5G) network. Some embodiments relate to uplink request design in a 5G network.

The use of 3GPP LTE systems has increased with the proliferation of different types of devices communicating with multiple network devices. With the advent of services such as video streaming, this has increased both the number of user equipments (UEs) and the broadband used by these user devices, and has made the LTE network increasingly tight. To increase capacity, next-generation LTE networks may be capable of applying Multiple Input Multiple Output (MIMO). MIMO systems use multipath signal propagation to communicate with UEs over the same or overlapping frequencies via multiple signals from the same evolved Node B (eNB), which will interfere with each other (if they are on the same path on). This increase in uplink or downlink data can be dedicated to one UE to increase that by the number of beams. The effective bandwidth of the UE (single-user MIMO or SU-MIMO) may be distributed across multiple UEs (multiple user MIMO or MU-MIMO) using different beams for each UE.

However, beam formation can complicate many transmission and reception issues. For example, when a UE intends to request a resource for uplink data transmission, the eNB cannot know the beam used by the UE for scheduling request reception. To address this, repeated schedule request transmissions may be used to allow the eNB to perform beam scanning for stable scheduling request detection. This can undesirably increase the system management burden associated with scheduling request delivery.

SUMMARY OF THE INVENTION AND EMBODIMENT

The following embodiments and figures are illustrative of the specific embodiments so that those of ordinary skill in the art will practice. Other embodiments may incorporate structural, logical, electrical processes, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. The embodiments set forth in the scope of the patent application cover all available equivalents of those claims.

1 shows an example of a portion of an end-to-end network architecture for a Long Term Evolution (LTE) network with multiple components of a network, in accordance with some embodiments. As used herein, an LTE network refers to both LTE and LTE Upgraded (LTE-A) networks and other versions of the LTE network to be developed. Network 100 may include a Radio Access Network (RAN) (e.g., as described, E-UTRAN or Evolved Universal Land Radio Access Network) 101 and core network 120 (e.g., display) coupled together via S1 interface 115. For evolution Package Core (EPC)). For convenience and simplicity, in this example, only a portion of the core network 120 and the RAN 101 are displayed.

The core network 120 may include a Mobility Management Entity (MME) 122, a Serving GW 124, and a Packet Data Network Gateway (PDN GW) 126. The RAN 101 may include an evolved Node Bs (eNB) 104 (which is operable as a base station) for communicating with User Equipment (UE) 102. The eNB 104 may include a jumbo eNB 104a and a low power (LP) eNB 104b. The eNB 104 and UEs 102 can apply the synchronization techniques described herein.

The MME 122 is functionally similar to the control plane of the legacy Serving GPRS Support Node (SGSN). The MME 122 can manage mobility aspects in access, such as gateway selection and tracking area list management. The Serving GW 124 can terminate the interface towards the RAN 101 and the routing data is encapsulated between the RAN 101 and the core network 120. In addition, the Serving GW 124 may be a local mobility anchor for inter-eNB handover, and may also provide anchoring for inter-GPP mobility. Other responsibilities may include legal interception, fees, and some policy enforcement. Serving GW 124 and MME 122 may be implemented in one physical node or in separate physical nodes.

The PDN GW 126 can terminate the SGi interface towards the Packet Data Network (PDN). The PDN GW 126 can route data between the EPC 120 and the external PDN, and can perform policy enforcement and charging data collection. The PDN GW 126 may also provide anchor points for mobility devices with non-LTE access. The external PDN can be any kind of IP network, as well as an IP Multimedia Subsystem (IMS) domain. PDN GW 126 and service GW 124 can be in a single Implemented in an entity node or in a separate entity node.

The eNB 104 (mega and mini) may terminate the air interface protocol and may be the first contact for the UE 102. In some embodiments, eNB 104 may implement various logic functions for RAN 101, including but not limited to RNC (Radio Network Controller Function), such as radio bearer management, uplink and downlink dynamic radio resource management and Data packet scheduling, and mobility management. According to an embodiment, the UEs 102 may be configured to communicate orthogonal frequency division multiplexing (OFDM) communication signals with the eNB 104 over a multi-carrier communication channel in accordance with OFDMA communication techniques. The OFDM signal can include a plurality of orthogonal subcarriers.

The S1 interface 115 may be an interface separating the RAN 101 from the EPC 120. It can be divided into two parts: S1-U, which can carry traffic information between the eNB 104 and the serving GW 124; and an S1-MME, which can be a signal transmission interface between the eNB 104 and the MME 122. The X2 interface can be an interface between several eNBs 104. The X2 interface can consist of two parts: X2-C and X2-U. X2-C may be a control plane interface between several eNBs 104, and X2-U may be a user plane interface between several eNBs 104.

With a cellular network, the LP unit 104b can generally be used to extend coverage to indoor areas where there is insufficient outdoor signal, or to increase network capacity in densely populated areas. In particular, it is desirable to use different sized cells, jumbo cells, microcells, picocells, and femtocells to amplify the coverage of a wireless communication system to improve system performance. Units of different sizes may operate on the same frequency band, or may operate on different frequency bands, each unit operating in a different frequency band, or only units of different sizes Operate on different frequency bands. As used herein, the term LP eNB means any fairly suitable LP eNB for implementing a smaller unit (less than a jumbo unit), such as a femto unit, a pico unit, or a micro unit. A femto unit eNB is typically provided by a mobile network operator to its home or business customer. A femtocell may generally be the size of a home gateway or smaller and is typically connected to a broadband line. The femtocell can be connected to the mobile operator's mobile network and provides additional coverage typically in the range of 30 to 50 feet. Thus, LP eNB 104b may be a femto eNB because it is coupled through PDN GW 126. Similarly, a picocell may be a wireless communication system that typically covers small areas, such as within a building (office, shopping center, station, etc.) or the nearest aircraft. A pico unit eNB can typically be connected to another eNB via an X2 link (such as via its base station controller (BSC) function to a jumbo eNB). Therefore, the LP eNB may be implemented with the pico unit eNB because it can be coupled to the jumbo eNB 104a via the X2 interface. The pico unit eNB or other LP eNB 104b may incorporate some or all of the functionality of the jumbo eNB LP eNB 104a. In some cases, this may be referred to as an access point base station or an enterprise femto unit.

The communication on the LTE network can be divided into several 10ms frames, each of which can contain 10 1ms subframes. Each sub-frame of the frame may have two 0.5ms slots in sequence. Each subframe can be used for uplink (UL) communication from the UE to the eNB or downlink (DL) communication from the eNB to the UE. In one embodiment, the eNB may allocate a greater number of DL communications than the UL communication in a particular frame. The eNB can schedule transmissions over multiple frequency bands (f ₁ and f ₂ ). Resources are allocated for use in subframes in a frequency band, which may be different from those in another frequency band. Depending on the system used, each slot of the subframe may contain 6 to 7 OFDM symbols. In one embodiment, the subframe may contain 12 subcarriers. The downlink resource grid may be used for downlink transmission from the eNB to the UE, while the uplink resource grid may be used for uplink transmission from the UE to the eNB or from the UE to another UE. The resource grid may be a time-frequency grid, which is an entity resource in the lower row in each slot. The smallest time-frequency unit in the resource grid can be represented as a resource element (RE). Each row and column of the resource grid may correspond to one OFDM symbol and one OFDM subcarrier, respectively. The resource grid may contain resource blocks (RBs) that describe the mapping of physical channels to resource elements and entity RBs (PRBs). The PRB may be the smallest unit resource that can be allocated to the UE. The resource block may be 180 kHz wide in frequency and 1 slot long in time. In frequency, the resource block may be a 12 x 15 kHz subcarrier or a 24 x 7.5 kHz subcarrier width. For most channels and signals, 12 subcarriers can be used per resource block depending on the system bandwidth. In Frequency Division Duplex (FDD) mode, both the uplink and downlink frames may be 10 ms and separate frequencies (full duplex) or time (half duplex). In Time Division Duplex (TDD), the uplink and downlink subframes can be transmitted on the same frequency and multiplexed in the time domain. The duration of the resource grid 400 in the time domain corresponds to one subframe or two resource blocks. Each resource grid may contain 12 (subcarriers) * 14 (symbols) = 168 resource elements.

Each OFDM symbol may contain a cyclic prefix (CP) that can be used to effectively remove inter-symbol interference (ISI) and fast Fourier transform (FFT). cycle. The duration of the CP can be determined by the delay spread of the highest degree of prediction. Although distortion from previous OFDM symbols may exist within the CP (CP with sufficient duration), the previous OFDM code does not enter the FFT period. Once the FFT period signal is received and digitized, the receiver can ignore the signal in the CP.

There may be many different physical downlink channels that are passed using these resource blocks, including the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH). Each downlink subframe can be divided into a PDCCH and a PDSCH. The PDCCH can normally occupy the first two symbols of each subframe, and carries information about the transport format and resource allocation related to the PDSCH channel and H-ARQ related to the uplink shared channel, among other things. News. The PDSCH can transmit user data and higher layer signals to the UE and occupy the rest of the subframe. In general, based on channel quality information provided from the UEs to the eNB, downlink scheduling (dispatching control and sharing channel resource blocks to UEs within the cell) may be performed at the eNB, and then downlink resource assignment information may be transmitted. To each UE on the PDCCH used (assigned to) the UE. The PDCCH may contain Downlink Control Information (DCI) in one of a number of formats indicating how the UE discovers and decodes material transmitted from the resource grid on the PDSCH in the same subframe. The DCI format may provide details such as the number of resource blocks, the type of resource allocation, the modulation scheme, the transport block, the redundancy version, the coding rate, and the like. Each DCI format may have a Cyclic Redundancy Code (CRC) and be agitated with a Radio Network Temporary Identifier (RNTI) that identifies the target UE for which the PDSCH is intended. specific The use of the RNTI of the UE may limit the decoding of the DCI format (and thus the corresponding PDSCH) to only the intended UE.

In addition to the PDCCH, an enhanced PDCCH (EPDCCH) can be used by the eNB and the UE. Unlike the PDCCH, the EPDCCH can be configured to allocate resources blocks for PDSCH under normal conditions. Different UEs may have different EPDCCH configurations that are configured via Radio Resource Control (RRC) signal transmission. Each UE may be configured with an EPDCCH of an array, and the configuration may also be different between the groups. Each EPDCCH group may have 2, 4, or 8 PRB pairs. In some embodiments, in a particular subframe, the resource blocks configured for EPDCCHs may be used for PDSCH transmission, and if within the subframe, the resource blocks are not used for EPDCCH transmission.

The term "transmission medium" will be used to include any intangible medium capable of storing, encoding, or transporting instructions executed by communication device 400, and including digital or analog communication for facilitating communication of the software. Signal or other intangible media.

In addition to the many types of MIMO that can be used by 5G systems, it is also possible for 5G systems to use high frequency bands (cm and millimeter waves) for communication between the eNB and the UE (or UE to UE) because these wavelengths can provide Wider bandwidth to support future integrated communications systems. Due to the combination of MIMO, the use of high frequency bands can be reduced due to increased bandwidth availability Reduce the amount of variables on multiple networks. In order to implement communication using high frequency bands, the MIMO beam forming the gain can compensate for potentially severe path loss caused by atmospheric attenuation at these higher frequency bands, as well as improve signal to noise ratio (SNR) and amplify the coverage area. By aligning a particular transmitted beam to the target UE, the radiated energy can be concentrated for higher energy efficiency and mutual UE interference is suppressed.

However, in a MIMO system, the UE may select the best of the plurality of beams transmitted by the eNB for receiving the plurality of signals and transmit the signals to the eNB using the direction indicated by the best beam. While it would be desirable to have the eNB know which beam is best for communicating with the UE, unfortunately this information may not be available to the eNB. That is, the eNB may not know which beam is being used by the UE, and therefore which direction is used to receive the scheduling request (SR). The eNB may thus scan all directions of the entire beam, causing the UE to repeatedly transmit the SR many times (at least equal to the number of beams). This can be exacerbated when multiple eNBs (such as LTE eNBs and 5G eNBs) provide different services to the UE and when the UE has a relatively high mobility, so that the optimal beam can be changed quite quickly (eg, the UE is at least Move a few times per hour (say 30) km). To avoid this, a specific SR or 5G Entity Random Access Channel (xPRACH) can be used to initiate 5G data transfer by the UE. In particular, an SR in an LTE link may be used for uplink requests in a 5G link for non-independent deployment, and xPRACH may be used for independent deployment, as explained in relation to the following embodiments .

FIG. 5 illustrates a non-independent LTE system for use in a non-independent LTE system, in accordance with some embodiments. Uplink request design. As shown, the 5G system includes a UE 502 that communicates with the LTE eNB 504 and the 5G eNB 506. UE 502, LTE eNB 504, and 5G eNB 506 may be shown in Figures 1-4. The LTE eNB 504 and the 5G eNB 506 may be connected via an X2 interface such that information provided from the UE 502 to the LTE eNB 504 may be forwarded to the 5G eNB 506 as desired. In some embodiments, the SR is transmitted to the LTE eNB 504 by using dedicated resources on the LTE link, and the UE 502 can initiate a 5G uplink scheduling procedure. The SR can be used for requests for uplink resources for 5G links.

Similar to the above, different physical uplink channels may include a Physical Uplink Control Channel (PUCCH) or a 5G PUCCH (xPUCCH) (hereinafter referred to simply as xPUCCH for convenience), which is used by the UE 502 to transmit uplinks. Route Control Information (UCI) to LTE eNB 504 or 5G eNB 506 and requesting Physical Uplink Shared Channel (PUSCH) or 5G PUSCH (xPUSCH) (hereinafter referred to simply as xPUSCH for convenience) to provide uplink data to LTE eNB 504 or 5G eNB 506. The xPUCCH can be mapped to UL control channel resources defined by orthogonal masks and two resource blocks (continuous in time, potentially hopping on the boundary between adjacent slots). xPUCCH can be used in many different formats, and UCI contains information based on that format. In particular, the xPUCCH may contain an SR that is used by the UE to request resources to transmit uplink data using PUCCH format 1. The xPUCCH may also contain an Acknowledgement/Retransmission Request (ACK/NACK) or Channel Quality Indicator (CQI)/Channel Status Information (CSI). The CQI/CSI may indicate an estimate of the existing downlink channel condition seen by the UE 502 to the LTE eNB 504 or the 5G eNB 506 to assist in channel dependent scheduling, And may include MIMO related feedback (eg, precoder matrix indication, PMI).

As shown in FIG. 5, at operation 512, the UE 502 can request resources using dedicated SR resources. The dedicated SR resources may be configured by the LTE eNB 504 or the 5G eNB 506 via a Radio Resource Control (RRC) signal transmission previously with the UE 502. UE 502 may be configured to have only one SR resource (for 5G links) or have two SR resources (one for uplink requests in LTE links and the other for uplinks for 5G links) request). The dedicated resources may be UE specific and may be related to the resource allocation index. A resource can have one or more of a dedicated time, frequency, or code assignment.

After successfully detecting the SR, at operation 514, the LTE eNB 504 can transmit a PDCCH formed according to the DCI format, the format containing an uplink grant for beam related information. In particular, the LTE eNB 504 can allocate uplink resources for transmitting a Buffer Status Report (BSR) in the LTE link by the UE 502. Although not shown, at this point, the LTE eNB 504 may, on the X2 interface, grant the UE 502 an uplink grant indication to the 5G eNB 506, or may wait until the 5G eNB 506 is notified later.

As shown in FIG. 5, UE 502 can receive an uplink resource allocation from LTE eNB 504. At operation 516, the UE 502 can responsively transmit a BSR on the PUSCH in the allocated uplink resource, which is carried in a Medium Access Control (MAC) Protocol Data Unit (PDU). The MAC PDU can be used to inform the eNB of the amount of data in the UE buffer to be transmitted. In addition to the BSR, the UE 502 can use the allocated resources to report 5G beam measurements. 5G shot The beam measurement may allow the 5G eNB 506 to transmit signals using the appropriate beam in the 5G link. The 5G beam measurement may contain information obtained from the beam reference signal (BRS) of the best beam received by the UE 502 from the 5G eNB 506, or BRS received power (BRS-RP) measurements by the UE 502. The optimal beam can be represented as a unique identifier that associates the beam with a known transmission point on the network. The UE 506 can continuously monitor the periodic beam transmission (reference signal) by the 5G eNB 506 for this measurement.

When the BSR and 5G beam measurement reports are received by the LTE eNB 504 using the LTE link, the LTE eNB 504 can determine the appropriate location and, in some embodiments, can determine the best beam. Alternatively, the LTE eNB 504 can provide 5G beam measurement report information to the 5G eNB 506 on the X2 interface for the 5G eNB 506 to determine the appropriate allocation and/or optimal beam. At operation 518, the 5G eNB 506 can transmit the xPDCCH using the best beam using the 5G link. The xPDCCH may contain an uplink grant for transmitting uplink data over a 5G link. In particular, based on the BSR information, as indicated by the UE 502, the 5G eNB 506 can allocate appropriate resources and modulation and coding schemes (MCS) included in the uplink grant for uplink data.

After receiving the uplink grant, the UE 502 can transmit the uplink data on the xPUSCH 520 using the 5G link. Thus, although the initial transmit SR and BSR/5G beams are reported on the LTE link, the UE 502 can receive the assignment and transmit the data on both 5G links.

6 illustrates another uplink request design for a non-independent LTE system, in accordance with some embodiments. As shown, the 5G system includes LTE The eNB 604 communicates with the UE 602 of the 5G eNB 606. UE 602, LTE eNB 604, and 5G eNB 606 may be shown in Figures 1 through 4 and may operate in a manner similar to the same entity in Figure 5. In some embodiments, the UE 602 can initiate a 5G uplink scheduling procedure by transmitting the SR to the LTE eNB 604 using dedicated resources on the LTE link. The SR can be used for requests for uplink resources for 5G links. However, unlike the embodiment of Figure 5, resources for the BSR can be allocated using 5G links. In this case, beam alignment between 5G eNB 606 and UE 602 may already be present.

Similar to the above, at operation 612, the UE 602 can request resources using dedicated SR resources. The dedicated SR resources may be configured by the LTE eNB 604 or the 5G eNB 606 via RRC signal transmission with the UE 602. UE 602 may be configured with only one SR resource (for 5G links) or configured with two SR resources, one for uplink requests in the LTE link and the other for 5G links. Uplink request.

After successfully detecting the SR, the LTE eNB 604 can determine that the 5G resource is desirable and provide this information to the 5G eNB 606 on the X2 interface. However, unlike the embodiment shown in FIG. 5, the LTE eNB 504 may not perform further actions. At operation 614, the 5G eNB 606 can transmit an xPDCCH formed according to the DCI format, the format containing an uplink grant for beam related information. The 5G eNB 606 already has information related to the best beam for communicating with the UE 602. For example, from the time the SR is received, the 5G eNB 606 can use beam information that is determined or provided within a predetermined amount of time (which may be based on the UE 602 mobility rate). 5G The eNB 606 can allocate uplink resources for transmitting the BSR in the 5G link by the UE 602. In some embodiments, the 5G eNB 606 can allocate additional uplink resources for transmitting 5G beam measurement reports in the 5G link by the UE 602 to update the information. The 5G eNB 606 can use the best beam to transmit this information to the UE 602.

UE 602 can receive an uplink resource allocation from 5G eNB 606. At operation 616, the UE 602 responsively transmits the BSR to the 5G eNB 606 with the allocated uplink resources on the 5G link. In this case, because the 5G eNB 606 can know the best beam for communicating with the UE 602, the UE 602 can avoid transmitting 5G measurement reports, and thus, fewer resources can be allocated by the 5G eNB 606 and used by the UE 602.

When the BSR is received by the 5G eNB 606 using the 5G link, at operation 618, the 5G eNB 606 can transmit the xPDCCH using the best beam using the 5G link. The xPDCCH may contain an uplink grant for transmitting uplink data. Based on the BSR information, the appropriate resources and MCS may be allocated by the 5G eNB 606 in the uplink grant transmitted by the 5G eNB 606.

After receiving the uplink grant, the UE 602 can transmit the uplink data on the xPUSCH 620 using the 5G link. Thus, although the SR is initially transmitted on the LTE link, the UE 602 can then communicate with the 5G eNB 606 to transmit the BSR, receive the allocation, and transmit the data on the 5G link.

7 illustrates another uplink request design for a non-independent LTE system, in accordance with some embodiments. The 5G system includes an LTE eNB 704 and The UE 702 communicated by the 5G eNB 706. UE 702, LTE eNB 704, and 5G eNB 706 may be shown in Figures 1 through 4 and perform at least some of the same functions as the similar devices of Figures 5 and 6. In some embodiments, by transmitting the SR to the LTE eNB 704, the UE 702 can initiate a 5G uplink scheduling procedure. The SR can be used to request uplink resources for the 5G link. However, unlike the embodiment shown in FIG. 5 or FIG. 6, the SR in the embodiment shown in FIG. 7 may not be transmitted using resources dedicated to the 5G uplink data transfer request.

That is, at operation 712, the UE 702 may use non-dedicated SR resources to request resources for uplink transmissions using the 5G link's data. In this case, the UE 702 may only have one SR resource configured for the LTE link. Although a non-dedicated SR resource is being used, a new logical channel ID (LCID) in the MAC layer may be defined for the UE 702 to request uplink resources in the 5G link. The LCID can be used to distinguish whether an uplink request is for an LTE link or a 5G link. The UE 702 can therefore use the SRID of the LCID in the LTE link to indicate that 5G resources are being requested. The LCID can be defined in accordance with 3GPP Technical Specification 36.321.

That is, the MAC header can have a variable size (in octets) and contains the LCID, length field, format field, and extended field. The length field may indicate the length (in bytes) of the corresponding MAC SDU or variable size MAC Control Element. The format field indicates the size of the length field. The extended field indicates if any further fields appear in the MAC header. LCID (5-bit) identifies the corresponding MAC SDU The logical channel case, or the type of corresponding MAC control element, or the padding for DL-SCH, UL-SCH, and MCH, respectively.

After successfully detecting the SR, the LTE eNB 704 may extract the LCID and determine that the UE 702 is requesting 5G resources. At operation 714, the LTE eNB 704 may thus transmit a PDCCH containing an uplink grant for beam related information to the 5G eNB 706. The LTE eNB 704 can allocate uplink resources for transmitting beam related information in the LTE link by the UE 702.

The UE 702 can receive an uplink resource allocation from the LTE eNB 704 and operate accordingly. In particular, at operation 716, the UE 702 can transmit BSR and 5G beam measurements on the PUSCH in the allocated uplink resource. As described above, the 5G beam measurement may contain information of the best beam received by the UE 702 obtained from the BRS, or BRS-RP measurements by the UE 702. In addition to the SR at operation 712 (or instead of the SR at operation 712), the BSR and 5G beam reports may use the LCID. In particular, a corresponding MAC control element can be defined, which can include a 5G beam measurement report. This MAC Control Element may be transmitted in operation 716, in an LTE RACH procedure, or transmitted with the BSR for uplink data transmission triggered by the SR at operation 712.

When receiving a 5G beam measurement report via the LTE eNB via the LTE eNB, similar to FIG. 5, the LTE eNB 704 can instruct the 5G eNB 706 to allocate a resource request for the 5G link to the UE 702, and Either or both of the BSR and/or 5G beam reports are provided via the X2 interface. The 5G eNB 706 can subsequently determine the best beam, and at operation 718 The xPDCCH is transmitted using the best beam using a 5G link. The xPDCCH may contain an uplink grant for transmitting uplink data. As described above, based on the BSR information, the 5G eNB 706 can allocate appropriate resources and MCS included in the uplink grant for uplink data based on the BSR.

After receiving the uplink grant, the UE 702 can transmit the uplink data on the xPUSCH 720 using the 5G link. As in Figures 5 and 6, in Figure 7, although the SR and BSR/5G beams are initially transmitted on the LTE link, the UE 702 can receive the allocation and transmit the data on both 5G links.

8 illustrates another uplink request design for a non-independent LTE system, in accordance with some embodiments. The 5G system may include a UE 802 that communicates with the LTE eNB 804 and the 5G eNB 806. UE 802, LTE eNB 804, and 5G eNB 806 may be shown in Figures 1-4. As in the above embodiment, the UE 802 can initiate a 5G uplink scheduling procedure by transmitting an SR to the LTE eNB 804 for the uplink resources of the 5G link. At operation 812, the UE 802 can request resources using non-dedicated SR resources.

Unlike the previous embodiment, instead of transmitting resources for the BSR and perhaps the 5G beam measurement report, at operation 814, the LTE eNB 804 can responsively transmit the PDCCH sequence for the contention free RACH procedure on the 5G link. In particular, LTE eNB 804 may transmit an xPRACH transmission with a designated preamble to indicate a contention free RACH procedure. Similar to the PDCCH containing the resources for the BSR, the PDCCH order can be transmitted on the LTE link. The preamble index indicating the xPRACH transmission may be a predetermined preamble The reference (eg, defining a single preamble for xPRACH) may be selected from a pre-indexed group that indicates xPRACH transmission. The pre-indexed group ID can be obtained via previous BRS-RP measurements. The information indicating the pre-index or pre-index group ID and the order for transmitting the xPRACH may be obtained by the UE 802 before being transmitted by the RRC signal before transmitting the SR.

In some embodiments, the xPDCCH sequence may be transmitted over the 5G link via the 5G eNB 806, rather than via the LTE link, via the LTE eNB 804, for the SR of the 5G link before transmitting the xPDCCH containing the xPRACH sequence The information is provided from the LTE eNB 804 to the 5G eNB 806 on the X2 interface. Moreover, in some embodiments, if the PDCCH (or xPDCCH) sequence is not received within the configured time window by RRC or other higher layer signaling, the UE 802 may determine that the SR has expired or is not received by the LTE eNB 804. And send another SR. The period of expiration may depend on the type of UE (UE priority), the material to be transmitted by the UE 802 (data priority), the network load measured by interference, for example, and other factors.

The UE 802 can decode the xPDCCH order for initiating a contention free RACH procedure via the 5G link. At operation 816, the UE 802 can transmit an xPRACH to the 5G eNB 806. The UE 802 may select one of a random access radio network temporary identifier (RA-RNTI) that may be determined by the number of slots of the RACH preamble and the preamble.

When receiving the xPRACH, the 5G eNB 806 can then perform a beam scan based on the xPRACH to determine the best beam. 5G eNB806 can The best beam is used to transmit the xPDCCH using the 5G link at operation 818. The xPDCCH may contain an uplink grant for transmitting uplink data. As described above, based on the BSR information, the 5G eNB 806 can allocate the appropriate resources and MCS included in the uplink grant for the uplink data.

After receiving the uplink grant, the UE 802 can transmit the uplink data on the xPUSCH 820 using the 5G link. In some embodiments, the UE 802 can also transmit a BSR with uplink data.

9 illustrates an uplink request design for an LTE-acne system, in accordance with some embodiments. The 5G system includes a UE 902 that communicates with the 5G eNB 904. UE 902 and 5G eNB 904 may be shown in Figures 1 through 4. In general, as discussed above, for 5G systems, repeated xPRACH transmissions can be used to ensure stable detection using beam scanning by 5G eNBs. Similar to the non-independent embodiment described above (where SR can be applied to indicate a request to provide uplink data via a 5G link), in a separate embodiment, the xPRACH can be utilized by the UE 902 for uplink synchronization.

Similar to some of the above embodiments, UE 902 may initiate a 5G uplink contention-free scheduling procedure by transmitting xPRACH to 5G eNB 904 for uplink resources of the 5G link. As illustrated, at operation 912, the UE 902 can use a dedicated xPRACH resource to request an uplink data resource. Information about xPRACH may be transmitted to the UE 902 via RRC or other higher layer signaling. Since the number of users in the 5G unit may be limited, one or more dedicated xPRACH resources are allocated. Used for a resource request to avoid the introduction of dedicated SR channels for 5G systems. The UE 902 may select one of a number of available xPRACH preambles and a Random Access Radio Network Temporary Identifier (RA-RNTI) determined from the number of pre-transmitted time slots.

One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or Code Division Multiplexing (CDM) may be used to multiplex the SR with xPRACH resources for random access. The configuration of the xPRACH resource for the SR can be configured via RRC signal transmission from a fixed anchor LTE unit or 5G unit. In one embodiment, the frequency resources and sequence groups of the xPRACH for random access may be mapped one-to-one to the frequency resources and sequence groups of the BRS. Additional resources may be allocated to the xPRACH for the SR, such as the n+1th subframe, where n is the subframe index for the xPRACH for random access. In another embodiment, the dedicated xPRACH preamble signature may be allocated for UE-specific manner of the SR (eg, RRC signal transmission).

The 5G eNB 904 can detect the xPRACH. In response, at operation 914, the 5G eNB 904 can transmit the xPDCCH with the uplink grant via the 5G link. The xPDCCH may contain resources for BSR and possibly 5G beam reporting. However, unlike the conventional RACH procedure, in response to xPRACH, the xPDCCH may contain a reduced random access response (RAR). In general, the full RAR may be addressed to the RA-RNTI and may include a Temporary Cellular Radio Network Temporary Identifier (C-RNTI) and a timing advance value in addition to the uplink granting resources to compensate for the UE 902 and the 5G eNB 904. Round trip delay between. In some embodiments, instead of full RAR information, Such as timing advance and C-RNTI may already be known before transmitting xPRACH, such as via an RRC_CONNECTED message. Therefore, the 5G eNB 904 can avoid transmitting this information to save management burden and simplify the procedure. Furthermore, because the C-RNTI can be known by the UE 902, the reduced RAR message carried in the xPDCCH can be agitated using the C-RNTI in the Cyclic Redundancy Check (CRC).

When receiving the xPDCCH at operation 914, the UE 902 may decode the xPDCCH and determine resource allocation. At operation 916, the UE 902 may subsequently transmit the BSR and/or 5G beam measurement report to the 5G eNB 904 using the 5G link.

Upon receiving the xPRACH, the 5G eNB 904 may subsequently perform a beam scan based on the xPRACH to determine an optimal beam for communicating with the UE 902. At operation 918, the 5G eNB 904 can use the best beam to transmit the xPDCCH using the 5G link. The xPDCCH may contain an uplink grant for transmitting uplink data. As described above, based on the BSR information, the 5G eNB 904 can allocate the appropriate resources and MCS included in the uplink grant for the uplink data.

After receiving the uplink grant, at operation 920, the UE 902 can transmit uplink data on the xPUSCH. The uplink data can be transmitted to the 5G eNB 904 using a 5G link.

FIG. 10 illustrates another uplink request design for an independent LTE system in accordance with some embodiments. The 5G system may include a UE 1002 in communication with the 5G eNB 1004. UE 1002 and 5G eNB 1004 can be displayed in Figures 1 through 4. In this embodiment, the competition-free with fast uplink access is introduced. The xPRACH program.

By transmitting an xPRACH for the uplink resource of the 5G link to the 5G eNB 1004 at operation 1012, the UE 1002 can initiate a 5G uplink contention-free scheduling procedure. The xPRACH can be transmitted with the BSR (and perhaps the 5G beam measurement report). UE 1002 may use dedicated xPRACH resources to request uplink data resources. Information about xPRACH can be transmitted to the UE 1002 via RRC or other higher layer signaling.

The 5G eNB 1004 can detect the xPRACH and perform a beam scan based on the xPRACH to determine the best beam for communication with the UE 1002. At operation 1014, the 5G eNB 1004 may transmit an xPDCCH with an uplink grant for transmission of uplink data via a 5G link. The xPDCCH may contain reduced RAR information, as in Figure 9. The xPDCCH may contain an uplink grant. As described above, based on the BSR information, the 5G eNB 1004 can allocate the appropriate resources and MCS included in the uplink grant for the uplink data.

After receiving the uplink grant, at operation 1016, the UE 1002 can transmit uplink data on the xPUSCH. The uplink data can be transmitted to the 5G eNB 1004 using a 5G link. Because the number of messages between the UE 1002 and the 5G eNB 1004 is reduced compared to FIG. 9, the uplink access delay can also be substantially reduced.
