    METHOD AND APPARATUS FOR TRANSMISSING A RACH PREAMBLE ON A WIRELESS NETWORK
    BACKGROUND
    1. Field
    [001] The present disclosure is directed to a method and apparatus for transmitting a RACH preamble over a wireless network.
    2. Introduction
    [002] Currently, wireless communication devices, such as user equipment, communicate with other communication devices using wireless signals. When a Network Entity (NE), such as a Base Station (BS) or gNodeB (gNB), can create a number of narrow beams using a large number of antenna elements, the NE can transmit more than one Sync Signal block (SS) per period. Each SS block carries primary and secondary synchronization signals (PSS / SSS) and a Physical Diffusion Channel (PBCH) that can be transmitted (Tx) in the form of a beam. A set of SS bursts including one or more SS blocks, such as up to 64 SS blocks, can cover different spatial directions.
    [003] With potentially transmitting multiple SS blocks according to a predefined standard for SS block locations, the NE may need to provide a User Equipment (UE) SS block timing information, as an index for a given SS block of the SS burst set, and / or SS burst set timing information, as an SS burst set index. After detecting at least one SS block associated with the UE's NE Tx beams, the UE can determine
    Petition 870190113330, of 11/05/2019, p. 15/78
    2/44 full or partial timing, using at least knowledge of the predefined potential SS block locations, such as the SS block locations assumed by the UE, and the received SS block timing information. Full or partial information can include symbol timing, as a symbol limit, can include interval timing, as an interval limit, and can include frame timing, as a frame limit.
    [004] For mobility measurement and reporting, the UE can perform mobility measurement for one or more SS blocks in the SS burst set based on the signals in each SS block, such as SSS and / or Demodulation Reference Signal (DMRS ) of the PBCH. In addition, a measurement report can include measurement quantities, such as Reference Signal Received Power (RSRP), of one or more detected and measured SS blocks and corresponding SS block indices.
    [005] In Long Term Evolution (LTE), a RACH configuration index, such as Table 5.7.1-2 / 3/4 in 3GPP TS 36.211, determines the RACH preamble format and the preamble frequency and time resources RACH. In the new fifth generation RAT (5G), support for Dynamic Time Division Duplex (TDD) operation and potential Ultra Reliable Low Latency Communication (URLLC) services make it difficult to preset an uplink interval or the number of symbols uplink in a range. Consequently, the semi-static configuration of the RACH time and frequency resources may not

    3/44 be sufficient for the flexible use of radio resources.

    DETAILED DESCRIPTION
    [0017] Some modalities may provide a method and apparatus for communicating over a wireless network. According to a possible embodiment, an SS from an SS block of a set of SS bursts can be received. A measurement can be performed on at least the SS received from the SS block. A PBCH from the SS block can be received. The PBCH can include a first portion of the PBCH and a second portion of the PBCH. The first portion of the PBCH can carry at least a portion of the minimum system information. The second portion of the PBCH can carry timing information. Timing information may include information that includes at least an indication of an SS block index of the SS block within the SS burst set. The second
    Petition 870190113330, of 11/05/2019, p. 18/78
    5/44 portion of the PBCH can be demodulated and decoded. The SS block index of the SS block within the SS burst set can be determined at least based on demodulation and decoding. A measurement report can be transmitted. The measurement report may include a measurement quantity of the measurement in the SS received from the SS block and may include the determined SS block index.
    [0018] According to another possible modality, an indication of a set of RACH resources configured semi-statically can be received through an upper layer signaling. The top layer can be taller than a physical layer. An indication of the availability of a RACH resource of at least one RACH resource of the set of semi-statically configured RACH resources can be received via dynamic physical layer signaling. Dynamic physical layer signaling can be in several ranges, including a RACH range. The RACH range can include at least one RACH resource from the set of semi-statically configured RACH resources. A RACH resource available in the RACH interval can be determined based on the indication received from the set of semi-statically configured RACH resources and based on the indication received of the availability of the RACH resource from at least one RACH resource from the set of semi-statically configured RACH resources. . A RACH preamble can be transmitted on the RACH resource available in the RACH interval.
    [0019] FIG. 1 is an example block diagram of a system 100 according to a possible embodiment. System 100 can include user equipment (UE)

    110, at least one network entity 120 and 125, as a base station and a network 130. The UE 110 can be a wireless wide area network device, a user device, wireless terminal, a wireless communication device portable cord, a smartphone, a cell phone, a flip phone, a personal digital assistant, a personal computer, a selective call receiver, an Internet of Things (loT) device, a tablet, a laptop or any other user device capable of sending and receiving communication signals over a wireless network. At least one network entity 120 and 125 can be wireless wide area network base stations, can be NodeBs, can be enhanced NodeBs (eNBs), can be New Radio (NR) NodeBs (gNBs), such as 5G NodeBs , can be unlicensed network base stations, can be access points, can be base station controllers, can be network controllers, can be TRPs (transmit / receive points), can be different types of base stations and / or any other entities on the network that can provide wireless access between an UE and a network.
    [0020] Network 130 can include any type of network capable of sending and receiving wireless communication signals. For example, network 130 may include a wireless communication network, a cell phone network, a Time Division Multiple Access (TDMA) based network, a Code Division Multiple Access (CDMA) based network, a network based on Multiple Access by Orthogonal Frequency Division (OFDMA), Long Term Evolution network (LTE), NR network, network based on Third Generation Partnership Project (3GPP), communications network

    Ί / 44 via satellite, high-altitude platform network, Internet and / or other communication networks.
    [0021] In operation, the UE 110 can communicate with network 130 through at least one network entity 120. For example, the UE can send and receive control signals on a control channel and user data signals on a data channel.
    [0022] The methods can be used to transmit a PBCH with support for broadband and narrowband UEs. Two different SS block transmission modes can be used, depending on the cell's operating mode and / or the deployment scenarios and related configuration signaling. Modalities can provide an efficient way to deliver the SS timing information in a PBCH to a UE without requiring complete decoding of the PBCH.
    [0023] Modalities can also provide indication of SS timing and configuration of RACH resources. Some modalities may provide SS timing information, such as an SS block index and / or an SS burst set index, for transmission in a PBCH that does not require a UE to decode a Master Cell Block (MIB) of the neighboring cell prior to transfer and supports combining multiple PBCHs within a Transmission Time Range (TTI) PBCH to obtain reliable PBCH decoding. Some modalities may provide adaptation of periodicities of sets of SS bursts, such as 5, 10, 20, 40, 80 and 160 ms, with a fixed TCH PBCH. Some modalities can provide a determination
    Petition 870190113330, of 11/05/2019, p. 21/78
    8/44 flexible RACH time and frequency capabilities with support for dynamic TDD operation.
    [0024] If the SS block time information bits, such as an SS block index within a set of SS bursts, are encoded together with other minimum System Information (SI) bits carried by the PBCH, the PBCH information may be different for each SS block within the SS burst set. In addition, if more than one set of SS bursts can be transmitted by PBCH TTI and if its timing information, such as an index of set of SS bursts within PBCH TTI, is also explicitly indicated and encoded along with the other SI in the PBCH, then the number of Transport Blocks (TB) of the Diffusion Channel (BCH), at least different in the timing information, per PBCH TTI, can be very large. For example, the number of BCH TBs can reach the maximum number of SS blocks in the SS burst set multiplied by the maximum number of SS burst sets per PBT TTI. This can significantly increase the complexity of PBCH encoding in a Network Entity (NE), such as a gNodeB, and can negatively affect the power consumption of the network. In addition, it may be difficult or impracticable for an UE to combine multiple PBCHs within a given set of SS bursts and between sets of SS bursts within the TCH PBCH for reliable PBCH decoding. Thus, the PBCH resource may have to be over-provisioned to achieve a certain target coverage, which potentially leads to greater overhead of PBCH resources. In addition, a UE in a mode connected by Control
    Petition 870190113330, of 11/05/2019, p. 22/78
    9/44 Radio Resource (RRC) may have to perform full PBCH decoding for each detected neighbor cell in order to report measurement quantities along with the corresponding SS block indices. Forcing the UE connected to the RRC to decode the entire PBCH of a neighboring cell to run the report and the mobility measurement can result in a longer measurement gap or delay due to the complete decoding of the PBCH by the UE. In addition, PBCH decoding for each detected cell can increase the energy consumption of the UE.
    [0025] The implicit indication of SS block timing information, such as the use of different versions of PBCH redundancy, may allow an UE to combine multiple PBCHs into the SS burst set. Therefore, a UE can improve the demodulation performance of PBCH. However, the implicit indication method may still require full PBCH decoding to obtain SS timing information.
    [0026] FIG. 2 is an example of illustration 200 of the SS timing information block (STIB) and MIB RE mapping on the PBCH according to a possible embodiment. A PBCH can carry two blocks of information, such as a STIB and a MIB. In addition, each block of information can be coded separately, modulated to a separate set of Quadrature Amplitude Modulation (QAM), such as Quadrature Phase Shift Switching (QPSK), symbols, and mapped to a different set of Elements of Resource (REs) in the PBCH. The set of REs assigned to the MIB in the PBCH can be indicated as M-PBCH REs, and another set of REs assigned to the STIB can be indicated
    Petition 870190113330, of 11/05/2019, p. 23/78
    10/44 be indicated as S-PBCH REs, where M-PBCH can carry MIB and S-PBCH can carry STIB. M-PBCH REs and S-PBCH REs can be mutually exclusive. The partition of resources between M-PBCH and S-PBCH in the PBCH may depend on the sizes of MIB and STIB and the required code rates of S-PBCH and M-PBCH in each SS block, taking into account different levels of combination for M -PBCH and S-PBCH. For example, an S-PBCH carrying a 6-bit STIB can occupy 144 REs on 72 subcarriers (SCs) and an M-PBCH carrying a 50-bit MIB can occupy 432 REs on 288 SCs minus the SCs for the STIB, as shown in illustration 200 S-PBCH REs and / or M-PBCH REs can be mapped to one or more OFDM symbols, such as 2 OFDM symbols. In one example, S-PBCH REs can be mapped to one symbol after the SSS, while M-PBCH REs can be mapped to multiple OFDM symbols. In another example, S-PBCH REs can be mapped only to REs in the frequency band / region corresponding to the PSS / SSS. Assuming QPSK modulation, the example allocation of RE can result in a code rate of 0.021 for S-PBCH and a code rate of 0.058 for M-PBCH, in an SS block. With the combination of 3 or more M-PBCHs, a UE can achieve similar decoding performances for M-PBCH and S-PBCH. In addition, the number of REs allocated to S-PBCH can be determined so that the performance of STIB decoding on a given SS block can be similar to or better than a single PSS / SSS detection rate. Alternatively, M-PBCH REs can overlap partially or completely with S-PBCH REs, and a UE can first decode S-PBCH and cancel S-PBCH interference to decode M-PBCH.

    [0027] FIG. 3 is an example, illustration 300 of jointly coding STIB and MIB according to a possible embodiment. The STIB and MIB can be encoded together, but the resulting channel bits can be separated into two self-decoding units, where a UE can decode the STIB from a first unit and can decode the MIB from a second unity. The first unit can include at least the STIB as systematic bits and can include a fractional part of the MIB and parity bits, which are generated using the STIB and the fractional part of the MIB. In one example, the parity bits included in the first unit can be a portion of the jointly encoded parity bits that are based primarily on the systematic STIB bits and an optional fractional part of the MIB. For example, parity bits can make a significant contribution from the systematic STIB bits and optional fractional part of the MIB included in the first unit. The second unit can include at least the MIB as systematic bits and can include a total or part of the STIB and parity bits resulting from the MIB and all or part of the STIB. In another example, the second unit may include at least the remaining portion of the encoded bits together that were not included in the first unit, such as at least the portion of the systematic MIB bits and at least the portion of the encoded parity bit sets not included in the first unit. The first and second units can be modulated to different sets of modulation symbols and mapped to different sets of REs in the PBCH. Illustration 300 shows the coding together of
    Petition 870190113330, of 11/05/2019, p. 25/78
    12/44
    STIB and MIB. S-PBCH can represent the set of REs corresponding to the first unit and M-PBCH can represent the set of REs corresponding to the second unit.
    [0028] According to another possible modality, the STIB and MIB can be encoded together, resulting in the encoder output of a systematic bit stream, such as STIB and MIB, and a parity bit stream. At least the systematic bits corresponding to the STIB and a first portion of the parity bits in the stream of parity bits can be QAM, like QPSK, modulated and mapped to a first set of REs, such as S-PBCH REs, from PBCH REs. The first part of the parity bits can correspond to parity bits that make a significant contribution from at least the systematic STIB bits. The remaining portion of the systematic bit stream and parity bit stream not included in the first set of REs can be QAM, like QPSK, modulated and mapped to the remaining REPs of the PBCH, like M-PBCH REs. This remaining portion may or may not be self-decoding. In one example, at least the systematic bits corresponding to the MIB and a second portion of the parity bits in the stream of parity bits can be QAM, like QPSK, modulated and mapped to the remaining REs of the PBCH. The second portion of the parity bits may correspond to the parity bits of the stream of parity bits not included in the first portion of the parity bits.
    [0029] According to a possible embodiment, at least the STIB bits can be mapped to a portion of the data encoder input bit stream
    Petition 870190113330, of 11/05/2019, p. 26/78
    13/44 junction that has reliability equal to or greater than other information bits in the information bit stream. For example, the joint encoder can be a polar code and the STIB bits can be mapped to virtual channels of the polar code that have equal or less probability of error compared to the other virtual channels of the polar code.
    [0030] According to a possible modality, the STIB and MIB can have separate Cyclic Redundancy Check (CRC) parity bits. In another possible embodiment, the CRC parity bits together can be calculated from the STIB and MIB bits. In another possible modality, the CRC can be based only on MIB bits.
    [0031] The separate encoding of SS timing information from a MIB or the joint encoding of SS timing information and the MIB, such as the generation of two self-decoding units that carry different systematic bits of decoding together, may allow a UE does not perform complete PBCH decoding for reporting and measuring neighboring cells. In addition, an UE can combine several M-PBCHs for MIB decoding, which can increase the reliability of MIB decoding.
    [0032] The MIB may include at least part of a System Frame Number (SFN) and may include other minimum system information. The minimum system information can refer to the essential system information that the UE may need to acquire to access a cell or network. The MIB size, including CRC bits, can be
    Petition 870190113330, of 11/05/2019, p. 27/78
    14/44 less than 100 bits. According to a possible modality, the SFN can be a number between 0 and 1023 indicating a 10 ms radio frame index. The STIB may include at least one SS block index and may also include a portion of the SFN and / or an SS burst set index. The size, like the number of bits, of the STIB can be determined by the maximum number of SS blocks within an SS burst set and the maximum number of SS burst sets whose indexes are explicitly indicated by the STIB. For example, if the MIB carries the most significant 7 bits (MSBs) of the 10-bit SFN, the TCH PBCH is 80 ms, the maximum number of SS blocks per set of SS bursts is 64, and the minimum set frequency of bursts of SS is 5 ms, the STIB can carry at least 6 bits for the SS block index and can have up to 10 bits, such as 6 bits for the SS block index and 4 bits for the SS burst set index on PBCH TTI.
    [0033] Alternative modalities can be used for STIB information elements. A modality for STIB information elements can use an SS block index, such as 6 bits, within a set of SS bursts to support up to 64 SS blocks. A UE can combine several S-PBCHs between sets of SS bursts. According to a possible implementation, an SS burst set index within a PBCH TTI assuming that the shortest SS burst set periodicity can be included in the MIB and can be encoded together with the other SI in the MIB. This can allow an UE to combine multiple MPBCHs within a set of SS bursts, but the UE cannot combine M-PBCHs between multiple sets of SS
    Petition 870190113330, of 11/05/2019, p. 28/78
    15/44 bursts of SS. In some examples, the UE may be able to combine a portion of the M-PBCHs between several sets of SS bursts, for example, depending on how the joint coding is performed.
    [0034] According to any other possible implementation, an index of SS burst set within the PBCH TTI, assuming the standard periodicity of the SS burst set, can be included in the MIB and encoded together with the other SI in the MIB . This can allow a UE to combine multiple M-PBCHs between multiple sets of SS bursts within the standard burst interval of the SS burst, if the SS burst interval periodicity is set to be less than the burst burst periodicity. of standard SS. An SS burst set index within the standard SS burst set periodicity can be implicitly indicated. In one example, different scrambling sequences can be applied to M-PBCHs for different sets of SS bursts within the standard periodicity of the SS burst set. In another example, the PSS or SSS strings can be used to indicate the SS burst set index within the standard SS burst set periodicity. In another example, one or more different scrambling sequences applied to M-PBCHs, redundancy version of M-PBCH, PSS, SSS sequences or a combination of them can be used to indicate the different sets of SS bursts within the set interval periodicity. bursts of standard SS. The scramble sequence can be generated from a scramble code generator, such as a gold code generator. THE
    Petition 870190113330, of 11/05/2019, p. 29/78
    16/44 scrambling code generator can be (re) initialized at each burst interval of standard SS or PBCH TTI. In one example, there can be only one set of SS bursts with the standard periodicity of the set of SS bursts. In several instances, the same scrambling sequence can be used for all M-PBCHs within a set of SS bursts. In some instances, the same version of M-PBCH redundancy can be used for all M-PBCHs within a set of SS bursts.
    [0035] FIG. 4 is an example illustration 400 of the PBCH mapping within the PBCH TTI in which the SS burst set periodicity is set to 20 ms and the PBCH TTI is set to 80 ms according to a possible implementation. FIG. 5 is an example illustration 500 of the SSS mapping within the standard 20 ms SS burst set periodicity, where the SS burst set periodicity is set to 5 ms according to a possible implementation. An SS burst set index within a TCH PBCH cannot be included in the MIB, but it can be implicitly indicated. In one example, different scrambling sequences and / or a different version of redundancy can be applied to M-PBCHs by the periodicity of standard SS burst sets within the PBCH TTI, as shown in illustration 400. PSS or SSS sequences can be used to indicate the SS burst set index within the standard SS burst set periodicity, as shown in illustration 500. An UE can combine multiple M-PBCHs between multiple burst sets
    Petition 870190113330, of 11/05/2019, p. 30/78
    17/44 SS within the PBCH TTI. In several instances, the same scrambling sequence can be used for all MPBCHs within a standard SS burst set periodicity. In some examples, the same redundancy version of the M-PBCH can be used for all M-PBCHs within a standard SS burst set periodicity.
    [0036] Another modality for STIB information elements can use an SS block index in a set of SS bursts, such as 6 bits, and use an SS set index in a TCH PBCH assuming the set periodicity of bursts of standard SS, such as 2 bits for the case of PBCH TTI of 80 ms and the periodicity of set of bursts of standard SS of 20 ms. A UE may coordinate several S-PBCHs between the SS burst sets within the standard SS burst set periodicity.
    [0037] Another modality for STIB information elements can use an SS block index within a set of SS bursts, such as 6 bits, and use an SS set index within a TCH PBCH assuming the shortest periodicity set of SS bursts, such as 4 bits for the case of 80 ms PBCH TTI and the smallest set of SS bursts with a 5 ms periodicity. A UE can combine several S-PBCHs between the TCH PBCHs.
    [0038] Another modality for STIB information elements may use an SS block index within a set of SS bursts, such as 6 bits, and use a radio frame index within a TTI PBCH, such as 3 bits, in the 80 ms PBCH TTI case. With the periodicity of
    Petition 870190113330, of 11/05/2019, p. 31/78
    18/44 5 ms SS burst set, the SSS can indicate the frame time limit. A UE can combine multiple S-PBCHs between sets of SS bursts within a radio frame.
    [0039] According to another possible modality, the symbols modulated for STIB can be mapped to a subband overlapped in the frequency domain with the subband where PSS / SSS are transmitted. Then, a UE can operate with the bandwidth equal to the PSS / SSS bandwidth for measuring neighboring cells between frequencies. If the bandwidth of the PBCH is greater than the bandwidth of the PSS / SSS, the mapping described above the S-PBCH symbols in the frequency domain may allow the UE to operate with the bandwidth less than the bandwidth of the PBCH for measuring neighboring cells. This can reduce the EU's energy consumption.
    [0040] In the example illustration 200 described above, a PBCH bandwidth can correspond to a bandwidth of 288 consecutive subcarriers and the PBCH can cover 2 OFDM symbols within an SS block, while the bandwidth for PSS and SSS can correspond to a bandwidth of 144 consecutive subcarriers. Similar to PSS / SSS, PBCH can be transmitted with predefined sub carrier spacing and predefined transmission bandwidth. The S-PBCH can be mapped to the 72 central subcarriers of the 2 OFDM symbols of the PBCH resource.
    [0041] According to another possible modality, an UE receiver can combine channel bits for STIB only through sets of SS bursts, and gNodeB can
    Petition 870190113330, of 11/05/2019, p. 32/78
    19/44 transmit the STIB with a low code rate by allocating elements of super-provisioned resources to S-PBCH. According to a possible alternative embodiment, a part of the STIB can be encoded, such as 4 6-bit MSBs, and the information corresponding to the remaining least significant bits (LSB) can be implicitly indicated with scrambling sequences applied to the S channel bits -PBCH. Then, a UE can combine a pair of consecutive SS block S-PBCHs within the SS burst set and can potentially exploit the diversity of beams.
    [0042] According to a possible modality, the MIB can have 50 bits, including CRC bits. The DL bandwidth for 2 bits can be 25, 50, 75 or 100 Resource Blocks (RBs). The number of RBs can be a function of the carrier frequency band and the 2 bits can map to a different set of RBs for a different frequency band. For example, 100, 200, 300 or 400 RBs can be used for the 28 to 40 GHz frequency band. The MIB can include a portion of the system frame number information, such as 7 bits. The MIB can include information about the minimum remaining SI transmission, such as 10 bits. The MIB can include configuration information for a Physical Downlink Control Channel (PDCCH) that schedules a Shared Physical Downlink Channel (PDSCH) carrying the minimum remaining SI. Configuration information can include a frequency away from an SS raster, such as a central PSS / SSS frequency, to an initial subcarrier of a Common Control Channel Resource Set (CORESET), which can be used to schedule a common PDSCH . Configuration information can
    Petition 870190113330, of 11/05/2019, p. 33/78
    20/44 include the size of the common CORESET in terms of the number of symbols and the number of Resource Block Groups (RBGs). Configuration information can include the location, such as PRBs or RBGs, of the common CORESET. The MIB can include the SS block transmission mode, such as 1 bit. The MIB can include 14 spare bits. The MIB can include CRC, such as 16 bits.
    [0043] According to a possible modality for the configuration of the Random Access Channel (RACH), a UE can determine a RACH time and frequency resource based on the combination of semi-static configuration signaling and dynamic indication signaling. The RACH semi-static time and frequency resources can be configured specifically per cell and a gNodeB can indicate the real availability of the RACH resources configured in statistical terms through Downlink Control Information (DCI) in a RACH interval or close to the RACH interval, such as one or two intervals before the RACH interval. The RACH range can include one or more common RACH resources configured semi-statically, such as cell-specific. Considering that the number of uplink symbols available in a range can change on a range basis, the UE may have to adjust a preamble format in each RACH range.
    [0044] According to a possible implementation, the information for RACH resources can be indicated to the UE through a semi-static configuration signal. For example, the rate of occurrence of RACH intervals and an initial index of RACH intervals can be indicated. Like
    Petition 870190113330, of 11/05/2019, p. 34/78
    21/44 alternative, a set of RACH intervals can be indicated. In addition, the number of RACH occasions in the frequency domain per RACH interval (or in a given time instance) for a set of SS blocks, as equivalent to a set of gNodeB transmission beams, associated with the same time resource / RACH frequency can be indicated. This may be related to the average and / or expected number of RACH attempts on the RACH resources associated with the SS block set. In addition, the number of sets of RACH occasions in the frequency domain per RACH interval (or in a given time instance) can be indicated. Each set of RACH occasions that comprises one or more RACH occasions can be associated with a set of SS blocks or a set of gNodeB transmission beams. This may be related to the gNodeB antenna and / or the beam-forming architecture, such as several radio frequency (RF) chains. In addition, one or more RACH preamble formats can be indicated. Each preamble format can determine the number of RACH OFDM / SC-FDMA symbols per RACH preamble, the number of RACH preambles per RACH preamble format, a cyclic prefix length (CP) and a hold time duration. As the number of uplink symbols available in a range can vary dynamically, some RACH preamble formats, each of which may have a different number of RACH preambles and / or a different number of RACH OFDM / SC-FDMA symbols per preamble RACH, may need to be configured semi-statically.

    22/44
    [0045] Information for RACH resources can be indicated through dynamic signaling, such as DCI in the common group PDCCH. The common group PDCCH can be formed by a Tx beam with Tx beams associated with an addressed RACH resource. Similarly, the common group PDCCH can be spatially almost co-located with an SS block and / or a CSI-RS resource that can be associated with the addressed RACH resource. Then, UEs that select the addressed RACH resource based on the downlink link Tx beam selection (equivalently, SS block and / or CSI-RS resource selection) can receive and decode the common group PDCCH and determine whether to transmit RACH preambles or not in the addressed RACH resource. Whether the potential RACH resource configured in an interval is available or not, this can be indicated by explicit or implicit indication. The start and end locations, such as a start symbol index and an end symbol index, RACH resource or uplink OFDM / SC-FDMA symbols within a range can also be indicated. Alternatively, an indication of the RACH preamble format selected from the configured RACH preamble formats can be signaled.
    [0046] According to a possible modality, the UE can be configured by upper layers, such as semi-static RRC signaling, with intervals with RACH resources and periodicity, which can be additional to other RACH configuration signals. The UE can assume that the RACH resources are present in the configured range if the UE is not configured to monitor a common group PDCCH in the range or the UE cannot decode a PDCCH

    23/44 group common in the interval if configured to monitor a group common PDCCH. In one example, the UE can still identify all or part of the RACH resources configured semi-statically, which can be assumed by the UE as always available, based on information from the semi-static uplink / downlink configuration and / or SS blocks actually transmitted in a cell. If the UE decodes the group common PDCCH in the range, the group common PDCCH can include an indication of whether the configured upper layer RACH resource in the range can be used for RACH transmission and / or can signal a new RACH resource in the range UE can use for RACH transmission.
    [0047] According to another possible modality for the RACH configuration, a common RACH resource configuration of a transfer destination cell indicated in a transfer command may be different from a common RACH resource configuration announced in an Information Block. Transfer target cell (SIB) system. A specific EU RACH time / frequency resource for transfer can be selected from the company's RACH resource configuration indicated on the transfer command. Configuring additional RACH intervals for transfer UEs can reduce RACH-related latency during transfer, as a larger number of configured RACH intervals can potentially increase the RACH resources actually available. Thus, the common configuration of RACH resources indicated in the transfer command may have more RACH intervals or more time / frequency resources
    Petition 870190113330, of 11/05/2019, p. 37/78
    24/44
    RACH than the common configuration of RACH resources indicated in the SIB. This can accommodate fast transfer without affecting the UEs in the target cell, as the monitoring occasions of the group common PDCCH for non-transfer UEs in the destination cell and the system information of the destination cell can remain the same. According to a possible implementation, the common configuration of RACH resources indicated in the transfer command may include the common configuration of RACH resources announced in the SIB and an additional common configuration of RACH resources that provides additional RACH time / frequency resources.
