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.
MT (terminal function) of relay node (relay node) in Rel15, indicating time domain resources including: downlink time resources (DL, abbreviated as D), uplink time resources (UL, abbreviated as U), flexible time resources (Flex, abbreviated as F); the DU (base station function) of the relay node has the following time domain resources: downlink time resource (DL, abbreviated as D), uplink time resource (UL, abbreviated as U), flexible time resource (Flex, abbreviated as F), and unavailable time resource (resource that cannot be used for base station function).
Types of time resources for the base station function at least include one of the following types, one is Hard (abbreviated as H): the corresponding time resource type is always determined to be available for the base station function; one type is Soft (abbreviated as S): whether the respective time resources of the base station are available for the base station function, either by explicit or implicit control (IA or INA); yet another special type is unavailable (NA), i.e. the base station functionality is disabled.
The following table gives possible combinations of DU and MT behaviour, taking into account the half-duplex characteristics of the relay node. The definitions in the table are as follows:
MT: tx-terminal function: sending;
MT: rx-terminal function: receiving;
MT: tx/Rx — terminal devices can transmit or receive (but cannot transmit and receive simultaneously);
MT: NULL-terminal function is invalid;
DU: tx-base station function: sending;
DU: rx-base station function: receiving, that is, the relay device may schedule uplink transmission from or the terminal device;
DU: tx/Rx — base station functionality includes transmit and receive, meaning that base station functionality can be used to transmit and scheduled uplink transmissions (but Tx and Rx cannot be done simultaneously);
IA: means for indicating that a relay is available as a function of the base station indicates explicitly or implicitly; INA denotes that a relay explicitly or implicitly indicates unavailability as a unit of a base station function;
DU: NULL means that the base station function does not send, nor does it schedule uplink transmission with the terminal device.
The above functions apply to TDM operation, and the DU and MT cannot transmit and receive simultaneously. The following table lists the relay node base station functionality and terminal functionality configuration combinations.
TABLE 1 base station function and terminal function configuration of relay nodes
Because the uplink and the downlink of the subframe of the relay node are semi-static and even dynamically variable, but the binding relationship between the uplink random access signal transmission time and the downlink synchronous sequence block is required, the patent provides a method for determining the uplink random access signal transmission time of the relay node.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 shows an example of the function type of a relay node base station.
From left to right, the resource configuration types of the relay node base station functions are:
F-Hard, flexible-deterministic, to be confirmed for receiving uplink traffic or sending downlink traffic;
UL-H-uplink-determined, for reception;
DL-H-downlink-deterministic, for transmission;
DL-S + IA-downlink-undetermined + enable base station function for transmission;
F-S + IA-flexible-undetermined + enabling base station function, to be confirmed for uplink receiving or downlink sending service;
DL-S + IA-downlink-undetermined + enabling base station function for transmitting;
F-S + IA-flexible-undetermined + enabling base station function, to be confirmed for uplink receiving or downlink sending service;
fig. 2 shows an example of the function types of the relay node terminal.
When the relay node implements the terminal function, the transmission function cannot be implemented. When the relay node realizes that the terminal functions are respectively DL (downlink), UL (uplink) and F (flexible), the resource configuration type of the base station function of the relay node is DL-S-INA (downlink-undetermined-prohibited base station function) or UL-S-INA (uplink-undetermined-prohibited base station function).
Fig. 3 is a flowchart of an embodiment of the method of the present invention applied to a relay device.
In the embodiment, the relay equipment determines the sending time of a random access signal (PRACH) according to a semi-static signaling of an upper link. The method specifically comprises the following steps:
the type includes a first type, or the type includes a first type and a second type. The following step 12 specifies the first type, and the step 23 specifies the second type.
for the terminal function of the relay node, the resource of the uplink random access signal and the Synchronization Sequence Block (SSB) from the previous node have a binding relationship, such as the number of times and time of transmission.
And 14, when the symbol type of the sending time is an unavailable type, sending an uplink random access signal.
In step 14, the relay node sends the uplink random access signal only when the configured base station function has no data to send.
Because the uplink random access transmission resource of the relay node and the downlink synchronization sequence block transmission have a certain binding relationship, in order to ensure that the uplink access signal transmission resource of the relay node is effective, the terminal function of the relay node needs to be changed according to the uplink and downlink frame structure configured by the base station function of the relay node. When determining the resource bound with the synchronization sequence block, if the resource is available for the base station function, the terminal function is unavailable to send the random access signal, and the uplink random access signal can only be sent when the resource of the base station function is unavailable.
Further, the method also comprises the following steps:
and step 14A, when the symbol type of the sending time is determined or to be determined, forbidding sending the uplink random access signal.
Since the pending resources are not available at least at some times, it is assumed that these resources to be scheduled (Soft) cannot be used for the terminal function to transmit the random access signal when deciding on the synchronization sequence block bonding relationship.
The binding relation between the random access and the synchronous sequence block is difficult to change according to the change of the dynamic signaling, so when the binding relation between the synchronous sequence block and the terminal function resource is determined, the binding relation is only performed according to the semi-static signaling, and the configuration of the dynamic signaling is not considered.
It is assumed that the semi-static base station function configuration indicates that the resource to be finalized is invalid when the random access signal is transmitted. That is, the symbol determined to be typed is not used as a resource for transmitting the random access signal. Even if the dynamic signaling sets the symbol to be shaped as a terminal function (namely INA), the uplink random access signal is forbidden to be sent.
Fig. 4 is a flow chart of another embodiment of the method of the present application.
In an embodiment of the method of the present application, further, the method comprises step 23:
and 25, when the symbol type of the sending time is unavailable and the symbol type of the sending time is uplink or flexible, sending an uplink random access signal.
When the symbol type is flexible, further, before sending the uplink random access signal, the method embodiment of the present application further includes the following steps:
24A, receiving a third signaling, wherein the third signaling comprises an indication that the flexible symbol is used for uplink or downlink of a terminal, and the third signaling is a semi-static signaling; and setting the flexible symbol for the terminal uplink service according to the third signaling. In this embodiment, the order between step 24A and step 24 is not limited.
It should be noted that, the F-type time unit (e.g. symbol or subframe) may be configured to be used by the determined terminal unit through semi-static signaling, and the third signaling is used to configure the terminal function of the relay device, and the F-type time unit is used and dedicated for uplink data transmission.
Fig. 5 is a functional structure diagram of the relay device.
The embodiment of the present application further provides a mobile communication relay device, which includes a signaling module 51, a configuration module 52, and a transceiver module 53.
The signaling module is configured to receive a first signaling S1, where the first signaling includes an indication of a type for each symbol in a time domain unit; the first signaling is semi-static configuration signaling;
the configuration module is configured to configure the first type T1 of each symbol according to the first signaling; the first type comprises one of three states: determining type, unavailable type and pending type; a symbol of a deterministic type, in a base station function enabled state; an unavailable symbol in a base station function disabled state; the symbol to be shaped is in an undetermined state of a base station function or a terminal function;
the signaling module is further configured to receive a second signaling S2, where the second signaling includes an indication of a sending time of the uplink random access signal of the relay node; the second signaling is semi-static configuration signaling;
the receiving and sending module is used for receiving a synchronous sequence block SSB; and when the symbol type of the sending time is unavailable, sending an uplink random access signal PRACH.
Further, in the mobile communication device of the present application, when the symbol type of the transmission time is a deterministic type or a to-be-finalized type, the transmission of the uplink random access signal is prohibited.
Further, in the mobile communication device of the present application, the configuration module is further configured to configure a second type T2 of the unavailable type symbol according to the first signaling; the second type contains one of three terminal functions: an uplink type, a downlink type and a flexible type; an uplink symbol for transmitting service data; a downlink type symbol for receiving downlink service data; flexible symbols for transmitting or receiving traffic data.
The transceiver module 53 is further configured to transmit an uplink random access signal when the symbol type at the transmission time is uplink type or flexible type.
Further, in the mobile communication device of the present application, the signaling module is further configured to receive a third signaling S3, where the third signaling is a semi-static signaling and includes the flexible symbol for an indication of uplink or downlink of the terminal.
The configuration module is further configured to set the flexible symbol for a terminal uplink service according to the third signaling.
The transceiver module 53 is configured to receive an uplink service and transmit downlink service data when the relay device is used as a base station unit (the function is shown in fig. 1); when used as a terminal unit, the terminal unit is used for receiving downlink traffic and transmitting uplink traffic data (see fig. 2 for functions). And when the transceiver module works, for each time domain unit and symbol, the transceiver module works according to the resource type determined by the determining unit. It should be noted that the transceiver module cannot be used as both a base station unit and a terminal unit.
When the relay equipment determines the binding relationship between the synchronization sequence block and the uplink random access, firstly, the transmission opportunity of the random access signal which is effectively transmitted is determined, and the time unit occupied by the transmission opportunity is at least one of a symbol, a time slot or a subframe. The relay equipment judges effective uplink random access sending time according to time unit (such as symbol) information of a relay node configured by semi-static signaling, if the time unit configured to the base station function is Hard or Soft, the time unit is invalid, if the time unit configured to the base station function is NA, the time unit configured to the terminal function is further judged, and if the time unit is UL or Flex type UL, the time unit is judged to be an effective time unit capable of sending uplink random access. The working process of the relay device is not described herein again, as described in the method embodiment of the present application.
