Description

Method for determining resources, resource configuration method and equipment

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method for determining resources, a method for configuring resources, and a device for determining resources.

Background

With the rapid development of the information industry, especially the growing demand from the mobile internet and internet of things (IoT, internet of things), the future mobile communication technology is challenged unprecedented. As per the international telecommunications union ITU report ITU-R M [ imt. Beyond 2020.Traffic ], it is expected that in 2020, mobile traffic will increase approximately 1000 times as compared to 2010 (4G age), the number of user equipment connections will also exceed 170 billions, and the number of connected devices will be even more dramatic as the vast number of IoT devices gradually penetrate into the mobile communication network. To address this unprecedented challenge, the communications industry and academia have developed a wide range of fifth generation mobile communication technology research (5G), oriented in the 2020 s. The framework and overall goals of future 5G have been discussed in ITU report ITU-R M [ imt.vision ], where the requirements expectations, application scenarios and important performance metrics of 5G are specified. For new demands in 5G, ITU report ITU-R M [ imt.future TECHNOLOGY TRENDS ] provides information about technical trends for 5G, aiming at solving significant problems of significant improvement of system throughput, user experience consistency, scalability to support IoT, latency, energy efficiency, cost, network flexibility, support of emerging services, flexible spectrum utilization, etc.

The performance of random access directly affects the user experience. In conventional wireless communication systems, such as LTE and LTE-Advanced, a random access procedure is applied to various scenarios, such as initial link establishment, cell handover, uplink re-establishment, RRC connection reestablishment, etc., and is classified into Contention-based random access (content-based Random Access) and non-Contention-based random access (content-free Random Access) according to whether a user monopolizes a preamble sequence resource. In the random access based on competition, each user equipment selects a preamble sequence from the same preamble sequence resource in the process of attempting to establish uplink, and a plurality of user equipments may select the same preamble sequence to send to the network equipment, so that a conflict resolution mechanism is an important research direction in the random access, and how to reduce the conflict probability and how to quickly resolve the conflict which has occurred is a key index affecting the random access performance.

The contention-based random access procedure in LTE-a is divided into four steps as shown in fig. 1. In the first step, the user equipment randomly selects a preamble sequence from the preamble sequence resource pool and sends the preamble sequence to the network equipment. The network equipment carries out correlation detection on the received signals so as to identify a preamble sequence sent by the user equipment; in a second step, the network device sends a random access response (Random Access Response, RAR) to the user device, including a random access preamble sequence identifier, a timing advance instruction determined according to a delay estimate between the user device and the network device, a temporary Cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI), and a time-frequency resource allocated for a next uplink transmission by the user device; in a third step, the user equipment sends a third message (Msg 3) to the network equipment according to the information in the RAR. The Msg3 contains information such as a user equipment identifier, an RRC (radio resource control) link request and the like, wherein the user equipment identifier is unique to a user and is used for resolving conflicts; in the fourth step, the network device sends the conflict resolution identification to the user device, including the identification of the user device that wins the conflict resolution. After detecting the self-contained identification, the user equipment upgrades the temporary C-RNTI into the C-RNTI, sends an ACK signal to the network equipment, completes the random access process, and waits for the scheduling of the network equipment. Otherwise, the ue starts a new random access procedure after a delay.

For non-contention based random access procedures, the user equipment may be assigned a preamble sequence since the network equipment knows the user equipment identity. The user equipment does not need to randomly select a sequence when transmitting the preamble sequence, but uses the allocated preamble sequence. After detecting the allocated preamble sequence, the network device sends a corresponding random access response including information such as timing advance and uplink resource allocation. After receiving the random access response, the user equipment considers that the uplink synchronization is completed and waits for further scheduling of the network equipment. Thus, the non-contention based random access procedure only comprises two steps: step one, transmitting a preamble sequence; and step two, sending a random access response.

The random access procedure in LTE is applicable to the following scenarios:

initial access under rrc_idle;

2. reestablishing the RRC connection;

3. cell switching;

the RRC connection state downlink data arrives and requests a random access procedure (when the uplink is asynchronous);

the RRC connection state downlink and uplink data arrives and requests a random access process (when the uplink is asynchronous or the resource is not allocated to the scheduling request in the PUCCH resource);

6. and (5) positioning.

In LTE, the six scenarios described above use the same random access procedure.

Before the random access procedure, the UE needs to determine available random access resources, however, in the new communication system, the bandwidth is divided into one or more different frequency band parts (BWP), so how the UE determines available random access resources for random access becomes a problem that is put in the eyes of those skilled in the art.

In a new communication system, a network device (e.g., a base station, an access point device) may divide a bandwidth into one or more different frequency band parts (BWP), so that the network device needs to notify the user of frequency band part information used by the initial access and location information of random access resources at the time of the initial access. Therefore, how to inform the user equipment of the frequency band part information used by the initial access and the position information of the random access resource by the network equipment so that the user equipment can determine the position information of the random access resource to perform the initial access becomes a difficult problem put in the eyes of the person skilled in the art.

For a new system, there may be multiple Uplink BWP (UL BWP) available, and at the initial access, the ue does not obtain the configuration of the band portion in the network, nor the configuration of the random access resource in the network, so that the network cannot be normally accessed, and the network device needs to notify the ue of the configuration of the Uplink band portion and the random access resource. The network device informs the user of the configuration information of the initial uplink frequency band part and the frequency domain position information of the random access resource in a combined mode, and the user device can find the position of the available random access resource after acquiring the configuration information of the initial uplink frequency band part and the frequency domain position information of the random access resource.

Based on the technical problems to be solved, the embodiment of the invention provides a resource configuration mode.

The resource allocation method provided by the embodiment of the invention is used for allocating the initial activated uplink frequency band part and the corresponding random access resource, providing a precondition for the subsequent transmission of the allocation information of the initial activated uplink frequency band part and the corresponding random access resource to the UE, and transmitting the allocation information of the initial activated uplink frequency band part and the corresponding random access resource to the UE for random access, thereby informing the user of the frequency band part information used by the initial access and the position information of the random access resource, and enabling the user to acquire the allocation condition of the initial activated uplink frequency band part and the corresponding random access resource in time during the initial access, and normally accessing the network.

Specifically, in an embodiment of the present invention, the network device may divide the available uplink frequency domain resources into a plurality of different frequency band portions, wherein each frequency band portion is identified by an absolute physical resource block (physical resource block, PRB) index (index), as shown in fig. 3. The first band part starts from PRB index 0 to PRB index 99, the second band part starts from PRB index 100 to PRB index 199, and so on. The network device may pre-configure the number of PRBs occupied by each band portion, and the bandwidth occupied by each band portion (i.e., the number of PRBs occupied) may be different. At the initial access, the ue has not been accessed to the system, so the band setting in the system is not obtained, so the initially activated uplink band portion (initial active UL BWP) may not be found, and the location of the random access resource available in the system may not be determined at the same time, so in the embodiment of the present invention, the network device is in the system information:

The above-described embodiments of the present invention are described in full detail below by way of several preferred implementations:

embodiment one:

in the first embodiment, it will be described how a User Equipment (UE) obtains an initial active uplink frequency band portion and an available random access channel frequency domain location through configuration information of a network device. In the present invention, the frequency domain location may be represented by a frequency domain resource unit index, or one or more frequency domain resource unit intervals, where the frequency domain resource unit may be a Subcarrier (Subcarrier), a Subcarrier group (Subcarrier group), a physical resource block (Physical resource block, PRB), a physical resource block group (PRB group), or the like. In the description of the first embodiment, the physical resource blocks PRB are used as frequency domain resource units for simplicity.

Firstly, during initial access, the UE may search for a synchronization signal block (synchronization signal block, SS block) from a cell, find system information configured by the network device by successfully reading a broadcast message in the SS block, and obtain configuration information of an initial active uplink frequency band portion in the system information, that is, receive configuration information of the initial active uplink frequency band portion in the system information, where:

● The method for reading the PRB index (index) of the initial activated uplink frequency band part and the bandwidth of the frequency band part, which are directly configured by the network equipment, specifically comprises the following steps:

the PRB index and bandwidth are indicated directly with N bits. For example, prbindex=200, which is a frequency domain start position of the initially activated uplink band portion, is configured with 9 bits in the system information, and the bandwidth indicated by the 9 bits is 100 PRBs, as shown in fig. 3, that is, it is indicated that the initially activated uplink band portion starts from the 200 th PRB of the uplink bandwidth of the entire system and occupies 100PRB bandwidth.

The UE receives indication information from the network device indicating a frequency domain start position of the initially activated uplink frequency band portion, wherein the indication information is in the form of an index. The multiple possible PRB indices are indicated by N bits directly or by N-bit indices in a look-up table, and the bandwidth size is indicated by M bits directly or by M-bit indices in a look-up table. For example, four possible PRB indices are indicated by n=2 bits, and as shown in table 1, 2 bits respectively indicate that the possible PRB indices are: 0,100, 200, 300.

Table 1 example table of PRB index indication of frequency domain starting position of initial active uplink band portion

Bit value	PRB index of frequency domain starting position
		00	0
01	100
		10	200
11	300

Similarly, four possible bandwidths are indicated by m=2 bits, as shown in table 2, with 2 bits indicating the possible bandwidths as: 50 PRBs, 100 PRBs, 150 PRBs, 200 PRBs.

Table 2 example table of bandwidth indication for initial active uplink band portion

In addition, the PRB index of the frequency domain starting position of the initial active uplink frequency band portion and the bandwidth occupied by the frequency domain may be indicated by using an index of N bits in combination, and as shown in table 3, 4 possible combinations of PRB indexes and bandwidths occupied by the frequency domain may be indicated by using n=2 bits.

Table 3 example table of PRB index and bandwidth indication occupied by frequency domain for initial activation of frequency domain start position of uplink band portion

● Specifically, the PRB index of the frequency domain start position of the initial active uplink frequency band portion directly configured by the network is read, but the bandwidth of the initial active uplink frequency band portion is preset. For example, the network device presets the bandwidth of the initial active uplink frequency band portion as 100 PRBs, and the PRB index is notified by the above possible manners, which are not described herein.

● Specifically, the bandwidth of the band portion of the initially activated uplink band portion configured directly by the network device is read, but the PRB index of the frequency domain starting position of the initially activated uplink band portion is preset by the network. For example, the network device presets the PRB index of the initial active uplink band portion to start calculation for the 200 th PRB, and the bandwidth (i.e. the number of occupied PRBs) is notified by the above possible manners, which is not described herein.

● Specifically, the PRB index and bandwidth of the initially activated uplink band portion are both preset. For example, PRB index of the frequency domain starting position of the preset initial active uplink band portion is calculated for the 200 th PRB, and the bandwidth is preset to 100 PRBs.

● The index of the initially active upstream band portion of the network device configuration is read. At this time, the configuration information (starting PRB index and/or corresponding band part bandwidth) of all or part of the possible uplink band parts is notified to the ue in a preset manner, or in a system message, and each possible uplink band part corresponds to an index of the uplink band part. Meanwhile, the index (UL BWP index) of the initial active uplink band part, which is notified to the user equipment in the system message, may be notified by directly using the index of N bits, or the index of N bits may be notified in a table look-up manner, as shown in table 4, n=2 bits notify 4 BWP indexes possible as initial active uplink band parts.

Table 4 BWP index example table for initial activation of uplink band part

Bit value	UL BWP index
		00	0
01	1
		10	2
11	3

After the UE obtains the configuration information of the initially activated uplink frequency band portion configured by the network device, a starting position and/or a bandwidth of the initially activated uplink frequency band portion is determined according to the configuration information. Therefore, according to the determined configuration of the initial active uplink frequency band portion and the random access resource configuration information notified in the system information, the frequency domain positions of M (M > =1) available random access channels are determined, and initial access is performed according to the random access channels at the frequency domain positions, specifically:

■ When M random access channel resources are consecutive:

● The preset frequency domain starting point position of the first random access channel is the X th PRB or X PRBs from the starting point position of the initial activated uplink frequency band part.

X is the offset from the starting position of the initial active uplink band segment; for example, x=2, which illustrates that the frequency domain starting position of the first available random access channel is 2 PRBs after the starting position of the initial active uplink band segment.

Specifically, x=0; i.e. the frequency domain start position indicating the first available random access channel starts from the start position of the initial active uplink frequency band part.

● The UE receives an offset between the frequency domain starting position of the first random access channel configured by the network device and the starting position of the initial active uplink frequency band portion, and a configuration method of the offset is shown in fig. 3. For example, the network device configures the first available random access channel to be offset from the starting location of the initial active uplink frequency band portion by 3 PRBs, indicating that the frequency domain starting location of the first available random access channel is 3 PRBs after the starting location of the initial active uplink frequency band portion. In particular, the offset may be directly indicated by using N bits, or the offset may be indicated by using a table look-up manner using N bits, which is similar to the table look-up manner described above, and will not be described again.

● The UE reads the frequency domain starting point position of the first random access channel configured by the network device in the initial active uplink frequency band portion, such as the xth PRB of the initial active uplink frequency band portion. For example, the network device configures the first available random access channel to initially activate the 3 rd PRB of the uplink band segment. In particular, the value of X may be directly indicated by N bits, or the value of X may be indicated by using a table look-up manner of N bits, which is similar to the table look-up manner described above, and will not be described again.

● The UE reads the frequency domain starting point position of the first random access channel configured by the network device on the full frequency band, such as the xth PRB for the full frequency band portion. For example, the network device configures the first available random access channel to be the 303 th PRB in the full band portion. In particular, the value of X may be directly indicated by N bits, or the value of X may be indicated by using a table look-up manner of N bits, which is similar to the table look-up manner described above and will not be described in detail.

■ When M random access channel resources are discontinuous:

● The network equipment configures or presets the frequency domain starting point position of the first random access channel as the X PRB of the initial activated uplink frequency band part, or as the X PRB of the full frequency band part, or X PRBs which are far from the starting point position of the initial activated uplink frequency band part; then for other random access channels there are:

The UE reads the network device configuration or the preset interval bandwidth Y PRBs, as shown in fig. 5, and finds the frequency domain starting point of the first random access channel through the preset X value, and then determines the positions of the rest random access channels through the interval bandwidth Y of the configured adjacent random access channels. The value of Y may be directly notified by N bits or may be notified by a table lookup manner of N bits, which is similar to the table lookup manner described above, and will not be described again.

● The UE determines the frequency domain positions of the rest random access channels according to the symmetric frequency hopping rule configured by the network equipment; as described in fig. 6. After the UE determines the first random access channel, the UE symmetrically finds a second random access channel by taking the central position of the initial activated uplink frequency band part as an axis, and the frequency domain end position of the random access channel is different from the end position of the initial activated uplink frequency band part by X PRBs. The third random access channel start position is similarly determined by the frequency hopping rule after being spaced apart from the end position of the first random access channel by Y PRBs, and in the same way, Y may be 0.

In particular, presetting the interval bandwidth on the frequency domain as X PRBs, or configuring the interval bandwidth on the frequency domain as X PRBs by the network equipment; i.e. the starting position of the first random access channel from the initial active uplink frequency band part is X PRBs, and the adjacent random access channels are also spaced by X PRBs in the frequency domain, as shown in fig. 7. Specifically, the foregoing frequency hopping rule may also be used to determine other random access channels except the first random access channel, that is, after the UE determines the first random access channel, the UE symmetrically finds a second random access channel with the initial active uplink frequency band portion center position as an axis, where the frequency domain end position of the random access channel is different from the initial active uplink frequency band portion end position by X PRBs. The third random access channel starting position is similarly determined by the frequency hopping rule after being separated from the ending position of the first random access channel by Y PRBs.

Specifically, x=0; i.e. the network device presets the first random access channel starting from the starting position of the initial activation of the uplink band portion, and then the remaining random access channels are acknowledged with Y PRBs spaced apart by the adjacent random access channel, as shown in fig. 8. Specifically, the foregoing frequency hopping rule may also be used to determine other random access channels except the first random access channel, that is, after the UE determines the first random access channel, the UE symmetrically finds a second random access channel with the initial active uplink frequency band portion center position as an axis, where the frequency domain end position of the random access channel is different from the initial active uplink frequency band portion end position by X PRBs. The third random access channel starting position is similarly determined by the frequency hopping rule after being separated from the ending position of the first random access channel by Y PRBs.

Embodiment two:

in the second embodiment of the present invention, it will be described that the UE determines possible beam failure recovery request resources through the determined random access channel resources and beam failure recovery request resource information preset or configured by the network device.

Preferably, the initial active uplink frequency band portion and the frequency domain position of the corresponding available beam failure recovery request resource may be obtained through a similar method in the previous embodiment through configuration information of the network device, where the configuration method of the frequency domain position of the beam failure recovery request resource is the same as the configuration method of the frequency domain position of the random access resource, which is not described herein, and the time domain position of the available beam failure recovery request resource is the same as the time domain position of the available random access resource.

Preferably, the frequency domain location of the available beam failure recovery request resource may also be determined by the determined initial active uplink frequency band portion and the frequency domain location of the corresponding available random access channel resource, and the configured beam failure recovery request resource configuration information, where:

■ When the determined M available random access channels are consecutive:

● The UE finds the first available beam failure recovery request resource by spacing Z PRBs between the first beam failure recovery request resource and the frequency domain end position of the last random access channel, which is preset or configured by the network device, as shown in fig. 9. For example, if the network device presets or configures X to be 3PBR and each random access channel occupies 6 PRBs, the network device configures 4 available continuous random access channel resources at this time and configures Z to be 3 PRBs, it indicates that the frequency domain location of the first available beam failure recovery request resource starts from the 30 th PRB from the initial position of the initial active uplink band portion. The specific Z value may be notified by N bits, or the configured Z value may be obtained by looking up N bits, which is similar to that described in the above embodiment, and will not be described again.

In particular, Z may be preset or configured to 0, indicating that the random access channel and the beam failure recovery request resource are contiguous in the frequency domain.

● In addition, the UE may determine the subsequent available beam failure recovery request channels by presetting or configuring the interval between the adjacent two beam failure recovery request channels notified by the network device to be D PRBs, as shown in fig. 9. For example, if D preset or configured by the network device is 1 PRB, the end position of the previous beam failure recovery request channel frequency domain is added with d=1 PRB, and then the end position of the next beam failure recovery request channel frequency domain is the start position. The specific D value may be notified by N bits, or the configured D value may be obtained by looking up N bits, which is similar to that described in the above embodiment, and will not be described again.

In particular, D may be preset or configured to 0, indicating that the available beam failure recovery request resources are contiguous in the frequency domain.

■ When the determined M available random access channels are discontinuous:

● The UE finds the first available beam failure recovery request resource by a preset or network device configuration informing interval of the first beam failure recovery request resource and the frequency domain end position of the last random access channel of Z PRBs, as shown in fig. 10. For example, if X preset or configured by the network device is 3PBR, y=1 PRB is spaced between every two adjacent random access channels, and each random access channel occupies 6 PRBs, the network device configures 4 available continuous random access channel resources at this time, and Z configured is 3 PRBs, which indicates that the frequency domain position of the first available beam failure recovery request resource is from the 33 th PRB of the initial position of the initial active uplink frequency band portion. The specific Z value may be notified by N bits, or the configured Z value may be obtained by looking up N bits, which is similar to that described in the above embodiment, and will not be described again.

In particular, Z may be preset or configured to 0, indicating that the beam failure recovery request resource is immediately after the end of the random access channel in the frequency domain.

● In addition, the UE may determine the subsequent available beam failure recovery request channels by presetting or configuring the interval between the adjacent two beam failure recovery request channels notified by the network device to be D PRBs, as shown in fig. 10. For example, if D preset or configured by the network device is 1 PRB, the end position of the previous beam failure recovery request channel frequency domain is added with d=1 PRB, and then the end position of the next beam failure recovery request channel frequency domain is the start position. The specific D value may be notified by N bits, or the configured D value may be obtained by looking up N bits, which is similar to that described in the above embodiment, and will not be described again.

● Specifically, in both the above two methods, the frequency domain location of the beam failure recovery request resource is relatively determined by the location corresponding to the last random access channel. In the following manner, the present invention proposes a method for determining a frequency domain position of a corresponding beam failure recovery request resource according to each random access channel, that is, a distance value between a preset or network device configuration notification adjacent next random access channel and adjacent next beam failure recovery request resource and the random access channel is Y PRBs and D PRBs, respectively. As shown in fig. 11, when the ue confirms the first random access channel (prach#1) position, then according to y=5 PRBs and d=1 PRBs notified by the preset or network device configuration, the frequency domain starting position of the corresponding beam failure recovery request resource (bfrq#1) is known after 1 PRB from the random access channel ending position, and the frequency domain starting position of the corresponding next random access channel (prach#2) is after 5 PRBs from the random access channel ending position.
