Description

Uplink transmission method, device and user equipment

Technical Field

The present application belongs to the technical field of communications, and in particular, relates to an uplink transmission method, an uplink transmission device, and user equipment.

Background

In general, a network device may configure a channel state information reference signal (CHANNEL STATE information REFERENCE SIGNAL, CSI-RS) for a User Equipment (UE) in a connected state, so that the UE may perform functions such as time-frequency synchronization, measurement, and the like according to the received CSI-RS. Specifically, the network device may configure a corresponding transmission resource (e.g., flexible symbol) for the CSI-RS to perform transmission of the CSI-RS on the transmission resource.

However, when the UE receives the dynamic indication of the network device to perform uplink transmission, if the transmission resource of the uplink transmission overlaps with the transmission resource of the CSI-RS, the UE performs uplink transmission, and does not perform reception of the CSI-RS; however, since the CSI-RS is configured by the network device to the UE in the connected state, the UE in the connected state still needs to receive the CSI-RS, and therefore the network device still needs to send the CSI-RS, which may cause collision between uplink and downlink transmissions when the UE still performs uplink transmission.

The following explains some concepts and/or terms related to the uplink transmission method, the uplink transmission device and the user equipment provided by the embodiment of the present application.

1. Method for determining available uplink transmission resources

When determining resources for Physical Uplink SHARED CHANNEL (PUSCH), physical uplink control channel (physical uplink control channel, PUCCH) transmission or repeated transmission, determining available uplink transmission resources in uplink symbols (symbols) and flexible symbols configured by a network device, and when the following condition is satisfied, determining that the uplink transmission resources are available uplink transmission resources by the UE:

(1) The resources allocated by the PUSCH and the PUCCH are flexible symbols or uplink symbols;

(2) There is no synchronization signal block (synchronization signal block, SSB) transmission on flexible symbols.

If the UE receives a dynamic slot format indicator (slot format indicator, SFI) indicated by the PDCCH indicating that the flexible symbol is a downlink symbol and the resources of PUXCH (i.e., PUSCH or PUCCH) overlap with the downlink symbol, the PUXCH is not transmitted.

2. CSI-RS configured by network equipment for idle/inactive (idle) UE

At present, network equipment is supported to configure CSI-RS for idle/inactive UE, the CSI-RS is configured for connected UE, and the network equipment can also configure the CSI-RS for the idle/inactive UE. Since the UE in the connected state may release the connection or switch to other cells at any time, the network device may indicate to the UE whether the network device has transmitted CSI-RS through an indication of layer 1, such as a paging advance indication (PAGING EARLY indication (PEI) or paging downlink control information (PAGING DCI). If the CSI-RS is indicated not to be transmitted, the UE does not receive the CSI-RS.

The network device may configure CSI-RS to the idle/inactive UE through system information or RRC information. PEI is indicated by a physical channel or physical signal to indicate whether the UE needs to receive the paging PDCCH. The PEI may also carry information indicating whether the CSI-RS configured to the idle/inactive UE by the network device is transmitted.

The uplink transmission method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

In the prior art, if the UE receives a dynamic instruction to perform uplink transmission, and the uplink transmission overlaps with a symbol transmitted by the CSI-RS, the UE performs uplink transmission and does not perform reception of the CSI-RS. However, the CSI-RS is first the CSI-RS that the network device configures to the connected UEs, which still need to receive the CSI-RS, so the network device still needs to send out the CSI-RS. If the UE is still transmitting uplink, then the uplink and downlink transmissions collide at that time. In the conventional scheme, in case that dynamic uplink transmission and CSI-RS configured by a network device overlap on flexible symbols, if uplink transmission resources indicated by dynamic indication information such as downlink control information (downlink control information, DCI), random access response uplink scheduling grant (RAR UL grant) include flexible symbols, and the network device configures reception of CSI-RS on the flexible symbols, the UE does not receive the CSI-RS and transmits uplink transmission.

In the embodiment of the present application, when the network device configures the transmission resource of the CSI-RS and the CSI-RS is configured on the flexible symbol/slot/subband, if the resource overlaps with the transmission resource of the CSI-RS when determining the resource for transmitting uplink transmission (e.g., PUSCH, PUCCH), it is determined that the resource is not used for uplink transmission, i.e., uplink transmission is not performed on the resource, so as to avoid collision between uplink and downlink transmissions.

The uplink transmission method provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

An embodiment of the present application provides an uplink transmission method, and fig. 2 shows a flowchart of the uplink transmission method provided by the embodiment of the present application. As shown in fig. 2, the uplink transmission method provided in the embodiment of the present application may include the following steps 201 and 202.

Step 201, the UE acquires target information.

Step 202, the UE determines whether to perform uplink transmission on the first resource according to the target information.

In an embodiment of the present application, the target information includes at least one of the following: type information of the first resource and target indication information of the CSI-RS. Wherein the target indication information includes at least one of: the system comprises first indication information and second indication information, wherein the first indication information is used for indicating transmission resources of the CSI-RS, and the second indication information is used for indicating whether the CSI-RS is transmitted or not.

In the embodiment of the application, the network equipment can configure the CSI-RS to the UE (for example, idle state/non-active state UE), and the UE can receive the CSI-RS and perform functions such as time-frequency synchronization, measurement, automatic gain control (automatic gain control, AGC) and the like according to the CSI-RS.

It should be noted that the embodiment of the present application may also be applied to a phase tracking reference signal (TRACKING REFERENCE SIGNAL, TRS), which is an embodiment of CSI-RS, where one TRS is formed by combining multiple CSI-RS.

Alternatively, in the embodiment of the present application, the CSI-RS may be configured by the network device through a system information or radio resource control (radio resource control, RRC) release (release) message.

Optionally, in an embodiment of the present application, the type information of the first resource includes at least one of the following: uplink resources, downlink resources, flexible symbols, flexible time slots, and flexible subbands.

It should be noted that, the first resource may be understood as: the UE may determine whether the first resource can perform uplink transmission, i.e. whether the condition for performing uplink transmission is met.

It should be noted that, on the flexible symbol/flexible time slot/flexible subband, the network device may configure the UE to perform uplink transmission, or may configure the UE to perform downlink reception; further, the network device may indicate the transmission direction of the flexible symbol/flexible slot/flexible sub-band as uplink, downlink or still flexible with dynamic signaling, for indicating that no uplink transmission or no downlink reception is performed on the symbol/slot/sub-band.

Optionally, in the embodiment of the present application, the first indication information is indicated by system information or is indicated by higher layer signaling.

Optionally, in the embodiment of the present application, the second indication information is transmitted through a downlink control channel (for example, PDCCH), or is transmitted through a sequence.

Optionally, in the embodiment of the present application, the second indication information may specifically be indicated by PEI or paging DCI, where PEI is used to indicate whether the UE monitors a paging downlink control channel.

Optionally, in an embodiment of the present application, the downlink control channel is a paging downlink control channel, and the second indication information is further used to indicate at least one of the following: the UE monitors a paging downlink control channel and monitors a paging downlink data channel.

It should be noted that, the foregoing paging downlink control channel may be understood as: a downlink control channel scrambled with a cyclic redundancy check code (Cyclic Redundancy Check, CRC) is performed using a paging radio network temporary identity (paging radio network temporary identifier, P-RNTI).

Optionally, in an embodiment of the present application, the uplink transmission includes at least one of: transmission of an uplink data channel (e.g., PUSCH), transmission of an uplink control channel (e.g., PUCCH), transmission of a Sounding Reference Signal (SRS) REFERENCE SIGNAL, transmission of a random access channel (e.g., physical Random ACCESS CHANNEL (PRACH)).

Optionally, in an embodiment of the present application, the uplink data channel is at least one of the following: the uplink data channel of repeated transmission, the uplink data channel indicated by downlink control information DCI, the uplink shared channel of configuration authorization, and the uplink data channel corresponding to the random access message (for example, message 3 in the four-step random access process).

Optionally, in an embodiment of the present application, the PUSCH may be at least one of the following: PUSCH without repeated transmission, PUSCH with repeated transmission, PUSCH corresponding to message 3 (Msg 3) (i.e. PUSCH carrying random access message (i.e. Msg 3)), PUSCH configuring grant (configured grant).

Optionally, in the embodiment of the present application, the PUSCH in the repeated transmission is another PUSCH in the K repeated transmissions except the PUSCH in the first transmission. The PUSCH corresponding to message 3 (Msg 3) may be the PUSCH corresponding to Msg3 of the initial transmission or the retransmission.

It can be understood that, for K repeated transmissions, the network device ensures that at least one uplink transmission will actually perform transmission, for example, the first uplink transmission can always ensure transmission, and the first uplink transmission cannot be sent because of CSI-RS transmission, only in the uplink transmission from the second time, the UE performs the above determination, that is, determines whether to perform uplink transmission on the first resource according to the target information.

Optionally, in an embodiment of the present application, the uplink control channel is at least one of the following: the uplink control channel of the repeated transmission, the uplink data channel corresponding to the acknowledgement message of the random access message (e.g. message 4 in the four-step random access procedure or message B in the two-step random access procedure).

Optionally, in an embodiment of the present application, the PUCCH may be at least one of the following: PUCCH that is not repeatedly transmitted, PUCCH that is corresponding to an acknowledgement message of message 4 (Msg 4)/message B (MsgB), e.g. hybrid automatic repeat request acknowledgement information (HARQ-ACK), i.e. PUCCH that transmits HARQ-ACK for Msg 4/MsgB.

Optionally, in the embodiment of the present application, the PUCCH of the repetition transmission is other PUCCHs than the PUCCH of the first transmission in the K repetition transmissions.

Optionally, in an implementation manner of the embodiment of the present application, the target information includes at least type information of the first resource. The above step 202 may be specifically implemented by the following step 202 a.

In step 202a, when the first resource is a target type resource and the first resource overlaps with a transmission resource of the CSI-RS, the UE does not perform uplink transmission on the first resource.

In the embodiment of the present application, the target type resource is any one of the following: flexible symbols, flexible slots, flexible subbands.

It can be appreciated that if the CSI-RS is configured on a flexible symbol/flexible slot/flexible sub-band and the first resource comprises at least one symbol/Resource Element (RE) overlapping the flexible symbol/flexible slot/flexible sub-band, the UE does not send an uplink transmission on the first resource.

It should be noted that, the overlapping of the first resource and the transmission resource of the CSI-RS may be understood as: the first resource is partially overlapped or completely overlapped with the transmission resource of the CSI-RS, that is, at least one RE/Resource Block (RB)/slot/symbol in the transmission resource of the CSI-RS is the RE/RB/slot/symbol in the first resource.

In the embodiment of the application, when the CSI-RS is configured on the flexible symbol/flexible time slot/flexible sub-band, if the network equipment schedules uplink transmission, the uplink transmission resource also comprises the flexible symbol where the CSI-RS resource is located, and the UE does not perform uplink transmission on the flexible symbol/flexible time slot/flexible sub-band.

Optionally, in another implementation manner of the embodiment of the present application, the target information includes at least type information of the first resource. The above step 202 may be specifically implemented by the following step 202 b.

Step 202b, in the case that the first resource is an unavailable type of resource configured by the network device, the UE does not perform uplink transmission on the first resource.

It will be appreciated that if the first resource overlaps with some specific resources (i.e. resources of an unavailable type) configured by the network device, the UE does not perform uplink transmission on the first resource, i.e. the UE does not perform uplink transmission on resources of an unavailable type.

Optionally, in the embodiment of the present application, the unavailable type of resources configured by the network device may include resources of CSI-RS configured by the network device, such as flexible symbols, flexible slots, flexible subbands, and so on.

In the embodiment of the present application, the network device configures an unavailable symbol (invalid symbol), and for uplink transmission, the UE does not perform uplink transmission on an uplink resource overlapping with the unavailable symbol. Note that, for the unavailable symbol configured by the network device, a part of resources (for example, a part of REs, a part of symbols, or a part of RBs) may not be used for uplink transmission, or all of the resources may not be used for uplink transmission.

Optionally, in a further implementation manner of the embodiment of the present application, the target information includes at least target indication information. The above step 202 may be specifically implemented by the following step 202 c.

In step 202c, when the target indication information indicates that the CSI-RS is transmitted on the transmission resource of the CSI-RS, the UE does not perform uplink transmission on the first resource.

In this manner, the target indication information includes at least the second indication information, that is, when the second indication information indicates that the CSI-RS is transmitted on the transmission resource of the CSI-RS, the UE does not perform uplink transmission on the first resource.

In the embodiment of the application, under the condition that the network equipment informs the UE that the CSI-RS can be sent on the transmission resource of the CSI-RS through the second indication information, the UE does not send uplink transmission on the first resource.

Optionally, in the embodiment of the present application, if the UE receives the second indication information and the second indication information indicates that the CSI-RS is transmitted on the transmission resource of the CSI-RS under the condition that the first resource overlaps with the transmission resource of the CSI-RS, the UE does not perform uplink transmission on the first resource.

Optionally, in the embodiment of the present application, if the UE receives the second indication information and the second indication information indicates that the CSI-RS is transmitted on the transmission resource of the CSI-RS, and the first resource is a target type resource and the first resource overlaps with the transmission resource of the CSI-RS, the UE does not perform uplink transmission on the first resource.

Optionally, in a further implementation manner of the embodiment of the present application, the target information includes at least target indication information. The above step 202 may be specifically implemented by the following step 202 d.

In step 202d, when the target indication information indicates that the CSI-RS is not transmitted on the transmission resource of the CSI-RS, the UE performs uplink transmission on the first resource.

In this manner, the target indication information includes at least the second indication information, that is, when the second indication information indicates that the CSI-RS is not transmitted on the transmission resource of the CSI-RS, the UE performs uplink transmission on the first resource.

In the embodiment of the application, under the condition that the network equipment informs the UE that the CSI-RS is not sent on the transmission resource of the CSI-RS through the second indication information, the UE sends uplink transmission on the first resource.

Optionally, in the embodiment of the present application, if the UE receives the second indication information and the second indication information indicates that the CSI-RS is not transmitted on the transmission resource of the CSI-RS under the condition that the first resource overlaps with the transmission resource of the CSI-RS, the UE performs uplink transmission on the first resource.

Optionally, in the embodiment of the present application, if the UE receives the second indication information and the second indication information indicates that the CSI-RS is not transmitted on the transmission resource of the CSI-RS, and if the first resource is a target type resource and the first resource overlaps with the transmission resource of the CSI-RS, the UE performs uplink transmission on the first resource.

In the embodiment of the application, the network device can instruct whether the CSI-RS actually performs uplink transmission through the paging PDCCH or PEI, and the UE can not perform uplink transmission on the first resource (for example, flexible symbol/flexible time slot/flexible sub-band) under the condition that the CSI-RS actually performs transmission according to the instruction of the network device, otherwise, the UE can still perform uplink transmission on the first resource so as to avoid the conflict problem of uplink transmission and CSI-RS transmission.

Alternatively, in yet another implementation manner of the embodiment of the present application, the above step 202 may be specifically implemented by the following step 202 e.

Step 202e, in the case that the UE is not configured to receive the second indication information, the UE does not perform uplink transmission on the first resource.

In the embodiment of the present application, the second indication information may be indicated by PEI or paging DCI, and if the UE is not configured with PEI or receiving paging PDCCH, the UE does not perform uplink transmission on all symbols/slots/subbands of CSI-RS configured by the network device.

The embodiment of the application avoids the problem of resource conflict of the CSI-RS configured in the uplink transmission and idle state non-activated state, ensures the transmission of the CSI-RS, ensures that the UE can perform the functions of time-frequency synchronization, measurement, AGC and the like based on the CSI-RS, and improves the transmission performance.

For example, it is assumed that the transmission mode of the network device is a half duplex mode, that is, the network device cannot transmit and receive simultaneously in the carrier frequency when the time domain symbols overlap. If the network device supports simultaneous transmission and reception, i.e. the network device transmits in a first sub-band (subband) in the carrier, the network device may receive in a second sub-band, and it is assumed that at this time, different sub-bands in frequency include sub-bands with different properties, such as downlink sub-bands, uplink sub-bands, flexible sub-bands, etc. (which may be specifically configured by the network device), at this time, even if CSI-RS and uplink transmission are on the same symbol, but the sub-bands are different, the two may still be transmitted and received simultaneously, and only if the symbol and the sub-band overlap simultaneously, the two cannot be transmitted simultaneously. At this time, the PEI and the paging PDCCH may indicate whether the CSI-RS is actually transmitted with granularity of the subband, if the symbol and the subband of the uplink transmission have no CSI-RS, the UE may perform uplink transmission, otherwise the UE does not perform uplink transmission.

The embodiment of the application provides an uplink transmission method, wherein UE can determine whether uplink transmission is performed on a first resource according to target information, and the target information comprises at least one of the following items: type information of the first resource and target indication information of the CSI-RS. When uplink transmission and CSI-RS transmission are carried out, the UE determines whether uplink transmission is carried out on the first resource according to the type information of the first resource and/or the indication information of the CSI-RS, namely, the UE can determine whether the first resource is an available resource for uplink transmission according to the two information instead of directly carrying out uplink transmission on the first resource, so that the problem that collision occurs in uplink and downlink transmission can be avoided, the transmission of the CSI-RS can be ensured, and the transmission performance is improved.

Optionally, in the embodiment of the present application, after the step 202, the uplink transmission method provided in the embodiment of the present application further includes the following step 301.

Step 301, when the UE performs K repeated transmissions on the uplink transmission and the UE does not perform the uplink transmission for the nth time, the UE ignores the uplink transmission for the nth time, or the UE does not count the uplink transmission for the nth time in the K repeated transmissions.

Wherein K is an integer greater than 1, and n is a positive integer less than or equal to K.

Note that, the UE ignoring the nth uplink transmission may be understood as: the UE does not actually perform the nth uplink transmission, but counts the nth uplink transmission in the K repeated transmissions, that is, the number of times that the UE actually performs the repeated transmission is smaller than K, if n is smaller than K, the UE continues to perform the n+1th uplink transmission after ignoring the nth uplink transmission, and so on until performing the kth uplink transmission, and of course, if n=k, the UE does not continue the kth uplink transmission after ignoring the nth uplink transmission, that is, ends the K repeated transmissions.

Note that, the UE not counting the nth uplink transmission in K repeated transmissions may be understood as: the UE does not actually perform the nth uplink transmission, and does not count the nth uplink transmission, that is, the number of times that the UE actually performs the repeated transmission is equal to K, and the UE may continue to determine the available transmission resources to perform the uplink transmission until the K repeated transmissions are performed, that is, until the K counts are completed.

It can be appreciated that if the UE performs K >1 repeated transmissions on the uplink transmission and the transmission resource at the nth time is not transmitted due to overlapping with the transmission resource of the CSI-RS (e.g., flexible symbol/flexible slot/flexible subband, etc.), the UE may ignore the nth uplink transmission or defer the nth uplink transmission (i.e., the UE does not count the nth uplink transmission in the K repeated transmissions).

It should be noted that, in the uplink transmission method provided in the embodiment of the present application, the execution body may be an uplink transmission device, or a control module in the uplink transmission device for executing the uplink transmission method. In the embodiment of the present application, an uplink transmission device executes an uplink transmission method by using an uplink transmission device as an example, which describes the uplink transmission device provided by the embodiment of the present application.

Wherein the target type resource is any one of the following: flexible symbols, flexible slots, flexible subbands.

The determining module 31 is specifically configured to not perform uplink transmission on the first resource when the first resource is an unavailable type of resource configured by the network device.

In one possible implementation, the target information includes at least target indication information. The determining module 31 is specifically configured to, when the target indication information indicates that the CSI-RS is transmitted on the transmission resource of the CSI-RS, not perform uplink transmission on the first resource.
