Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to an uplink access sharing method, a configuration signaling, and a device.
Background
When both relay devices and terminal devices are present in a cell, both need to access the base station. If the same random access resource is configured, the configuration of the random access parameter is restricted. For example, because the power and capability of the relay device are high, when the relay device is located outside the cell radius of the main base station, it needs to try to access to the main base station, and then the main base station matches the relay device when configuring the random access parameter for the terminal, and GP and CP in the transmitted preamble format are large to meet the access of the relay device, or the number of cyclic shifts is large, thereby reducing the number of available cyclic shifts, and thus it is unreasonable to access to the terminal located within the cell radius. However, if the network configures independent random access resources for the relay device and the terminal device, signaling overhead is greatly increased, and it is not favorable for sharing the random access resources, which affects access capacity.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a cell including a relay device and a terminal device. In the cell there is both a relay device 61 and a terminal device 62, both of which are able to access the base station 60. The relay equipment and the terminal equipment respectively send random access sequences, and the base station equipment sends out random access response after identification.
Random access sequence xu,v(n) is generated as follows, where the base sequence is xu(i)，CvIs a cyclic shift, LRAIs the length of the sequence.
xu,v(n)＝xu((n+Cv)mod LRA)
When LRALength 139, step value N of cyclic shiftcsWhen the number of cyclic shifts is 10, the number v of cyclic shifts is 139/10, the rounding is 13, and CvIs 0, 10, 20, …, 120, with one root sequence, 13 random access sequences are generated. To generate 64 random access sequences, a total of 5 root sequences are required.
It should be noted that the value of the selected cyclic shift is related to the radius of the cell, and assuming that there are two terminals, UE1 is at the edge of the cell, UE2 is closer to eNB, UE1 uses a cyclic shift value of 0, and UE2 uses a cyclic shift value of Ncs. From the eNB perspective, the cyclic shift value of the UE1 is not 0 but other value X due to the existence of transmission delay, as long as the value X is less than Ncs, X and NcsThe autocorrelation value is 0, so the eNB will be able to distinguish between UE1 and UE2 in the access procedure, which is characteristic of ZC sequences. Therefore, the cell maximum coverage radius is limited by the cyclic shift value.
Fig. 2 is a flowchart of an embodiment of a method for uplink access channel sharing according to the present invention.
When the uplink access configuration signaling is sent to the terminal equipment, at least a first step value is included; and when the uplink access configuration signaling is sent to the relay equipment, at least a second step value is included.
Considering that the access radius of the relay device is larger than that of the terminal device, when the terminal and the relay configure the same resource, two cyclic shift step size values N may be defined for the same ZC root sequencecsSmall NcsLarge N for terminal equipment accesscsFor relay device access.
The prior art is to obtain the step size of the cyclic shift by a higher layer configuration parameter (zeroCorrelationZoneConfig). To support different cyclic shift step sizes of the relay and the terminal, two higher layer configuration parameters are introduced, one configuration parameter for the terminal (zeroCorrelationZoneConfig _ UE), i.e. identification of the first step value, for obtaining a relatively small cyclic shift step value, and the other configuration parameter for the relay (zeroCorrelationZoneConfig _ IAB), i.e. identification of the second step value, for obtaining a relatively large cyclic shift step value.
For example, the following table shows that the value of the first step size value identifier (zerocorrelationZoneconfig _ UE) for the terminal device is set to range from 0 to 10, and correspondingly, the first step size value is N in the 0 th to 10 th rows of the tableCSA numerical value; the value of the second step size value identification (zerocorrelationZoneconfig _ IAB) for the relay device is set to range from 11 to 15, and the second step size value is N in the 11 th to 15 th rows of the tablecsA numerical value; therefore, the cyclic shift of the terminal equipment is ensured to be small, and the cyclic shift of the relay equipment is ensured to be large.
TABLE 1 first step value (or second step value) identification index Table
(the above Table values are only examples, and the specific parameters are extracted from "Table 6.3.3.1-7: N" in 3GPP Standard 38.211csfor preamble formats with ΔfRA＝15·2μkHz where μ∈{0,1,2,3}”)
And 20, receiving a configuration signaling, and circularly shifting at least one root sequence by using the first step length value or the second step length value to obtain a random access sequence.
The existing mechanism is to configure parameters for the higher layers to obtain the root sequence and step value for generating random access sequences until a total of 64 random access sequences are generated. For example, 13 random access sequences are generated with one root sequence. To generate 64 random access sequences, a total of 5 root sequences are required.
For example, the relay device receives a configuration signaling, where the configuration signaling includes an identifier for indicating the second step value; circularly shifting at least one root sequence by using the second step value to obtain the second random access sequence; determining all or part of the second random access sequence as the set of second random access sequences.
For another example, the terminal device receives a configuration signaling, where the configuration signaling includes an identifier for indicating the first step size value; cyclically shifting the at least one root sequence by the first step size value to obtain the first machine access sequence; excluding the same portion as the second random access sequence from all the first random access sequences, and determining the portion as the set of the first random access sequences.
A random access sequence for a terminal device belonging to a set of first random access sequences; the random access sequence for the relay device belongs to the set of second random access sequences.
the random access sequence sent by the terminal device is the first random access sequence and is generated by at least one root sequence through cyclic shift under the condition of a first step value.
And the random access sequence sent by the relay equipment is the second random access sequence and is generated by cyclic shift of the at least one root sequence under the condition of a second step value.
fig. 3 is a diagram illustrating a set of random access sequences when the second step size is a multiple of the first step size.
As an optimized embodiment of the invention, the second step value is a multiple of the first step value. Excluding, from the set of first random access sequences, a first random access sequence that is identical to any one of the set of second random access sequences. The total number of random sequences contained in the first random sequence set and the second random sequence set is 64.
In order to support different cyclic shifts of the relay device and the terminal device, the base station side configures the cyclic shift step length of the relay device to be a multiple N (N is a positive integer) of the cyclic shift of the terminal device according to the coverage of the covered relay device, so as to ensure that the relay device generates a random access sequence by using the cyclic shift step length which is N times larger than that of the terminal device, and thus, the requirement that the coverage of the relay device is inconsistent with that of the terminal device is met.
It should be noted here that since the random access rate of the relay device is relatively low, a smaller number of random access sequences can be generated than the terminals.
As shown in FIG. 3, for a terminal device, N is configured when the higher layercsWhen 10, each ZC sequence needs 13 cyclic shifts to generate a random access sequence, and a total of 5 ZC sequences need to generate a total of 64 random access sequences according to the cyclic shifts, where each square indicates a random access sequence;
according to the high-level configuration of this patent, the relay device configures a step size value of 4 times, i.e., NcsEach root sequence generates 3 cyclically shifted random access sequences, and 15 random access sequences for relay devices may be generated. Specific cyclic shift value CvIs 0, 40 and 80. Each box in the figure represents one random access sequence and the grey boxes represent the set of second random access sequences. In the embodiment shown in fig. 3, the set of second random access sequences includes all of the second random access sequences.
To avoid collision, all N times of cyclic shifts are used for the relay device, and the remaining cyclic shifts are used for the terminal. C in the examplesvFinally, the number of random access sequences for relaying is 15 and the number of random access sequences for the terminal is 49, i.e. in all the first random sequences, the part (indicated by the dash ×) coinciding with the grey square is removed, resulting in a set of first random sequences.
Fig. 4 is a diagram of a set of second random access sequences including a portion of the second random access sequence.
Preferably, the set of second random access sequences comprises part of the second random access sequence. Excluding, from the set of first random access sequences, a first random access sequence that is identical to any one of the set of second random access sequences. The total number of random sequences contained in the first random sequence set and the second random sequence set is 64.
The base station configures the root sequence and cyclic shift special for the terminal and the relay to ensure the access sequence special for the terminal and the relay, and still takes the high-level configuration N of the terminal equipment as shown in FIG. 4cs10, relay device N cs40. C for terminal to generate random access sequence at second root sequencevRelay C, 40, 50, …, 120, which generates a random access sequence at the second root sequence v0. The terminal generates a cyclic shift value C of the random access sequence in the fourth root sequence v0, 10, 20, 30, 80, 90, 100, 110, 120; c of relay generating random access sequence at third root sequence v40. The terminal generates a cyclic shift value C of a random access sequence in a fifth root sequence v0, 10, 20, 30, 40, 50, 60, 70, 120; c of relay generating random access sequence in fifth root sequencevEach square in the figure represents one random access sequence, the grey squares represent the set of second random access sequences, being the part designated in all the second random access sequences (represented by the remaining dash ×.) the number of random access sequences used for relaying in this example is 3 in all the first random sequences, the part coinciding with the grey squares (represented by the dash ×) is removed, resulting in a set of first random sequences, the number of random access sequences used for the terminal being 61.
In the invention, the terminal and the relay device share the same sequence, two cyclic shift step values are introduced, and the design principle is that a small step value is used for the terminal device and a large step value is used for the relay device. There are three methods for indicating, one is to divide the configurable step value into two categories, such that one category is larger step value for the relay device, the other category is smaller step value for the terminal device, the other is to give the indication that the step value of the relay device is a multiple of the step value of the terminal device, and the third is to directly configure a part of the generated 64 access sequences to be used by the relay device according to the random access sequence with the larger step value.
An apparatus is further provided in an embodiment of the present application, where the apparatus is configured to receive a configuration signaling, where the configuration signaling includes an identifier for indicating the second step value; circularly shifting at least one root sequence by using the second step value to obtain the second random access sequence; determining all or part of the second random access sequence as the set of second random access sequences.
Preferably, the apparatus is configured to receive configuration signaling, the configuration signaling including an identifier indicating the first step size value; performing cyclic shift on the at least one root sequence by using the first step size value to obtain the first random access sequence; excluding the same portion as the second random access sequence from all the first random access sequences, and determining the portion as the set of the first random access sequences.
Further preferably, the device sends the random access sequence belonging to the set of the first random access sequence or the set of the second random access sequence. The random access sequence belongs to the set of first random access sequences when the device is provisioned in a terminal device 62; the random access sequence belongs to the set of second random access sequences when the device is provided in a relay device 61.
The embodiment of the present application further provides a device, which, when being configured in the base station device 60, sends the configuration signaling, receives the random access sequence, and determines that the random access sequence belongs to the set of the first random access sequence or the set of the second random access sequence.
